-Guard admin endpoints structurally (#514). An `onRequest` hook enforces `ADMIN_TOKEN` over every route that declares `{ admin: true, auth: 'admin' }` or is registered under `/admin/`, so a new admin endpoint is protected by where it lives rather than by its handler remembering to call `isAdminAuthorized`. `public: true` now means genuinely unauthenticated, and all seven admin routes declare the admin tier instead. The guard reads the matched route pattern, not `req.url`, so a percent-encoded path cannot route to an admin handler while reading as non-admin.

-Distinguish an unconfigured admin surface from a rejected token (#508). `checkAdminAuth` returns `authorized` / `unauthorized` / `not_configured`, and admin routes answer 503 `admin_not_configured` when `ADMIN_TOKEN` is unset, blank or an obvious placeholder, instead of a 401 that tells an operator their correct token is wrong. The structural admin hook makes the same three-way distinction, startup logs a warning when the surface is disabled, and `GET /status` reports `adminConfigured` — whether a token is set, never any part of its value.

-Ship the first real centralized-exchange adapter in `src/ingest/cex/` (issue #215). The directory previously held only the `CexAdapter` interface and a mock, so every cross-venue comparison compared Stellar venues against nothing. `CoinbaseAdapter` implements `CexAdapter` in full — `fetchTicker` and `fetchOrderBook` against Coinbase Exchange's public market-data endpoints — and is built and registered through a new exchange-agnostic `createCexAdapter(name)` factory (`registerCexAdapterFactory` wires concrete exchanges in).

Requests are throttled to Coinbase's published public limit (10 req/s per IP, burst up to 15) with a token bucket; a `429` honours `Retry-After` when present and otherwise backs off exponentially. Any outage, timeout, non-2xx, or malformed body degrades to a `null` return — the adapter never throws, so a dead exchange cannot take down the process or surface an error response. Prices carry a distinct `source` (`coinbase_cex`) and take the `network` from the caller rather than hard-coding it, so a CEX number is never mistaken for, or silently blended with, an on-chain one.

-The MCP server's spend cap is now cumulative, not just per call. `maxPrice`
-bounded a single payment, so an agent in a retry loop — or one told to "try each
-of these endpoints" — could pay that amount arbitrarily many times: every
-payment individually inside the limit, the sum unbounded. A per-call limit
-answers "how much can one mistake cost"; an operator's question is "how much can
-today cost".
-
-`SpendBudget` (`src/mcp/budget.ts`) adds a ceiling on the total paid by
-`paid_call` within one UTC day, configured with `MCP_DAILY_SPEND_CEILING`
-(default `$10.00`) alongside the per-call `MCP_MAX_PAYMENT_PRICE`. The day window
-was chosen over a sliding 24 hours because it answers the operator's question
-directly, needs one stored number rather than one entry per payment, and rolls
-over from the wall clock — so a restarted server resumes the same day's total and
-resets it after 00:00 UTC.
-
-Before a call is made the budget reserves its worst case, the per-call maximum,
-and refuses when that no longer fits what is left. It refuses with the new
-`ERR_BUDGET_EXCEEDED` code carrying the spent, ceiling, remaining and reset time
-in `details.budget`, so an agent can report being out of budget instead of
-looking broken; the refusal happens before the payment fetch, so no money moves.
-Both limits are in the `paid_call` description and the live totals are readable
-without spending, through the new `payment_budget` tool. The running total
-persists to `MCP_SPEND_STATE_FILE` (default `~/.lens-mcp/spend-state.json`) and is
-read back at startup, because a restart does not refund what the previous process
-already spent.
-

+
+The MCP server's spend cap is now cumulative, not just per call. `maxPrice`
+bounded a single payment, so an agent in a retry loop — or one told to "try each
+of these endpoints" — could pay that amount arbitrarily many times: every
+payment individually inside the limit, the sum unbounded. A per-call limit
+answers "how much can one mistake cost"; an operator's question is "how much can
+today cost".
+
+`SpendBudget` (`src/mcp/budget.ts`) adds a ceiling on the total paid by
+`paid_call` within one UTC day, configured with `MCP_DAILY_SPEND_CEILING`
+(default `$10.00`) alongside the per-call `MCP_MAX_PAYMENT_PRICE`. The day window
+was chosen over a sliding 24 hours because it answers the operator's question
+directly, needs one stored number rather than one entry per payment, and rolls
+over from the wall clock — so a restarted server resumes the same day's total and
+resets it after 00:00 UTC.
+
+Before a call is made the budget reserves its worst case, the per-call maximum,
+and refuses when that no longer fits what is left. It refuses with the new
+`ERR_BUDGET_EXCEEDED` code carrying the spent, ceiling, remaining and reset time
+in `details.budget`, so an agent can report being out of budget instead of
+looking broken; the refusal happens before the payment fetch, so no money moves.
+Both limits are in the `paid_call` description and the live totals are readable
+without spending, through the new `payment_budget` tool. The running total
+persists to `MCP_SPEND_STATE_FILE` (default `~/.lens-mcp/spend-state.json`) and is
+read back at startup, because a restart does not refund what the previous process
+already spent.

+Accounting is deliberately conservative: the wrapped x402 transport exposes only

-the execution price was compared with itself. It is now the shortfall of the
-execution price against the AMM reserve-ratio spot price, so it grows with
-order size against a fixed pool. Route selection and `estimatedOutput` are
-unchanged. Slippage is only reported for an AMM route; SDEX and SPLIT routes
-(and pairs with no AMM pool) have no size-independent spot reference, so the
-value stays 0 rather than reporting a cross-venue spread as slippage.

-# Changelog
-
-## 0.2.0
-
-### Minor Changes
-
-- bbe48e4: Add `/prices/history` endpoint backed by 1-minute price snapshots. A new `price_snapshots` table is appended to every minute by a snapshot ingester, queryable over a `[from, to]` window with optional `5m`/`1h` aggregation. A retention job prunes snapshots older than 30 days.
-
-### Patch Changes
-
-- 5a68745: Adopt changesets for versioning and release notes. Adds `@changesets/cli`, a release GitHub Actions workflow that opens a "Version Packages" PR for pending changesets and tags releases on merge, and contributor docs for the workflow.
-
-All notable changes to Lens are documented in this file.
-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).

-- Contributor documentation, issue templates, PR template
-- This changelog
-
-## [0.1.0] — 2025 initial deployment
-
-### Added
-
-- Fastify REST API with `GET /price/:assetA/:assetB`, `GET /status`, `GET /pools`
-- GraphQL endpoint via Mercurius
-- SDEX trade ingestion with checkpoint tracking
-- AMM pool snapshot ingestion
-- Best-route price calculation across SDEX and AMM
-- x402 micropayment gating via `@x402/stellar`
-- Prisma schema for price points, pools, and checkpoints
-- BullMQ aggregate refresh worker (optional, requires Redis)
-- Supabase Postgres support with scoped SSL handling
-- Deployed on Render at https://lens-ldtu.onrender.com
-
-### Fixed
-
-- `bestRoute.ts` AMM lookup — was using broken `code:code` join format; now queries via `pool_id`
-- Prisma binary target on Render (`debian-openssl-3.0.x`)
-- Supabase SSL cert error (scoped to supabase.com hosts)
-- BullMQ blocking startup — wrapped in try/catch, ingesters auto-restart

-
-## Development setup
-
-### Prerequisites
-- **Node.js 20+**
-- **PostgreSQL** (local or Supabase)
-- **Redis** (optional — for BullMQ workers)
-- A Stellar testnet account for x402 payments (if testing paid endpoints)
-
-### Clone and install
-
-```bash
-git clone https://github.com/Miracle656/Lens.git
-cd Lens
-npm install
-cp .env.example .env   # fill in DATABASE_URL, REDIS_URL, WATCHED_PAIRS
-npm run db:migrate     # apply committed migrations (prisma migrate dev) — do NOT `db push`
-npm run dev
-```
-
-API runs on `http://localhost:3002`.
-
-### Environment variables
-- `DATABASE_URL` — Postgres connection string (Supabase or local)
-- `REDIS_URL` — optional, enables aggregate refresh worker
-- `WATCHED_PAIRS` — comma-separated `CODE:ISSUER/CODE:ISSUER` (e.g. `XLM:native/USDC:GBBD...`)
-- `STELLAR_NETWORK` — this instance's default network, `testnet` or `mainnet` (default: `testnet`)
-- `ENABLED_NETWORKS` — optional, comma-separated networks to ingest (`testnet,mainnet`); falls back to `STELLAR_NETWORK`
-
-Per-network overrides use a `_TESTNET` / `_MAINNET` suffix (e.g. `HORIZON_URL_MAINNET`, `WATCHED_PAIRS_TESTNET`); see `.env.example` for the full list.
-
-## Commit conventions
-
-- `feat:`, `fix:`, `docs:`, `test:`, `refactor:`, `chore:`
-- Keep PRs focused
-
-## Before opening a PR
-
-```bash
-npx prisma generate
-npx tsc --noEmit
-npm run build
-npm test --if-present
-```
-
-## Testing
-
-Tests run under [Vitest](https://vitest.dev):
-
-```bash
-npm test                          # full suite (vitest run)
-npx vitest run path/to/file.test.ts   # a single file
-```
-
-The suite is ~53 files / ~520 tests covering route handlers, price math
-(including property-based tests with [fast-check](https://fast-check.dev)),
-the x402 flow, per-network config and ingesters, HTTP metrics, and integration
-scenarios under `tests/`. Open test work is tracked under
-[`area:tests`](https://github.com/Miracle656/Lens/labels/area%3Atests).
-
-## Releases
-
-Lens uses [changesets](https://github.com/changesets/changesets) for versioning and changelog generation.
-
-### Adding a changeset
-
-When you make a change that should appear in the changelog (a feature, fix, or any user-facing change), add a changeset in the same PR:
-
-```bash
-npx changeset
-```
-
-Pick the bump type (`patch` / `minor` / `major`) and write a short summary. This creates a markdown file under `.changeset/` — commit it alongside your change.
-
-### How a release happens
-
-1. When PRs with changesets are merged into `main`, the release workflow (`.github/workflows/release.yml`) opens (or updates) a **"Version Packages"** PR.
-2. That PR consumes the pending changeset files, bumps the version in `package.json`, and updates `CHANGELOG.md`.
-3. Merging the Version Packages PR bumps the version and creates a matching git tag and GitHub release.
-
-Lens is not published to a registry, so there is no publish step — releases are tag-only (`changeset tag`).

+Lens is not published to a registry, so there is no publish step — releases are tag-only (`changeset tag`).

-
-## Quickstart
-
-### REST
-
-```bash
-curl http://localhost:3002/status
-# {
-#   "ok": true,
-#   "network": "testnet",
-#   "watchedPairs": ["XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN"],
-#   "lastIndexedLedger": 53842917,  // illustrative — actual value depends on when /status is queried
-#   "lastProcessedAt": "2026-05-07T18:45:11.220Z",  // illustrative — actual value depends on when /status is queried
-#   "ingestLagSeconds": 4  // illustrative — actual value depends on when /status is queried
-# }
-#
-# /status answers for one network — pass ?network=mainnet (or the
-# x-network header) to check the mainnet indexer instead. ingestLagSeconds is
-# null until that network has ingested, and lastIndexedLedger is null until
-# its SDEX ingester has recorded a trade.
-```
-
-### GraphQL
-
-```bash
-curl -X POST http://localhost:3002/graphql \
-  -H "Content-Type: application/json" \
-  -d '{"query":"{ getPrice(assetA:\"XLM\", assetB:\"USDC\") { price assetA assetB pairKey bestRoute lastUpdated } }"}'
-# {
-#   "data": {
-#     "getPrice": {
-#       "price": 0.1245,
-#       "assetA": "XLM",
-#       "assetB": "USDC",
-#       "pairKey": "XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN",
-#       "bestRoute": "amm",
-#       "lastUpdated": "2026-05-07T18:46:02.114Z"
-#     }
-#   }
-# }
-```
-
-### MCP
-
-```bash
-# By default the MCP server speaks over stdin and stdout and listens on no
-# port; MCP_TRANSPORT=http serves Streamable HTTP on MCP_HTTP_PORT instead
-# (see "MCP server" below). Port 3002 is the HTTP API, which knows nothing
-# about MCP either way.
-npm run mcp:server
-
-# To drive it interactively, point the inspector at that command:
-npx @modelcontextprotocol/inspector npm run mcp:server
-# Tools and the keys it needs: examples/mcp-server/README.md
-# [
-#   {
-#     "name": "bazaar_search",
-#     "description": "Search for resources in a Stellar Bazaar node"
-#   },
-#   {
-#     "name": "paid_call",
-#     "description": "Make a paid API call to a Bazaar resource"
-#   }
-# ]
-```
-
-**What Horizon doesn't do:** Horizon's `/trade_aggregations` only covers SDEX. AMM pool prices (derived from reserve ratios) are not aggregated anywhere. Lens fills this gap.

-
-Every non-internal route above has a matching entry in [`openapi.yaml`](openapi.yaml);
-`tests/openapi.test.ts` boots the server and fails if a registered route is
-missing from the spec. Operator-only and non-HTTP routes (`/admin/keys*`,
-`/admin/usage*`, `/admin/webhook-delivery-failures`, `/metrics`, `/ws`, `/graphiql*`) are deliberately excluded via
-the commented allow-list in [`src/openapi/coverage.ts`](src/openapi/coverage.ts).
-In addition, live service responses are verified against their published schemas on a daily schedule (`05:00 UTC`) via `npm run spec:validate-live` — see [docs/live-spec-validation.md](docs/live-spec-validation.md).
-
-The `?network=testnet\|mainnet` query param (or `x-network` header) selects the
-Stellar network. It is validated on every request — an unrecognised value gets a
-`400` — and defaults to this instance's `STELLAR_NETWORK`. Only the routes whose
-spec entry declares a `network` parameter answer for the selected network; the
-ones listed below still read a single instance-wide network.
-
-Per-request today: `/price/:assetA/:assetB` (its VWAP, OHLCV, AMM and
-best-route reads), `/price/:assetA/:assetB/route`, `/price/:assetA/:assetB/depth`, `/book/:assetA/:assetB`,
-`/prices/history`, `/screener`, `/pools`, `/pairs`, `/spreads/:asset`,
-`/volumes/:asset`, `/status`, and the x402 payment `network`/`payTo`. That list
-is the same one `openapi.yaml` declares a `network` parameter on — if they ever
-disagree, the spec is the thing to fix.
-
-`GET /volumes/:asset` also reports the trade count, median trade size, largest
-trade's volume share, and `volumeConcentration`. Concentration is the HHI: the
-sum of squared individual trade volume shares (0 to 1; 1 means one trade
-accounted for all volume). The `provenance` object gives the venues and
-positive-volume sample count used and the total observed sample count
-(including zero-volume rows), plus the latest trade time and its age at the
-response's `endTime`.
-When the window has no trades, or its samples have no positive volume, derived
-size and concentration metrics are `null` and `status` explains why.
-
-Still reading across both networks, and ignoring the parameter:
-`/candles/:assetA/:assetB`, `/price/twap/*`, and `/price/vwap/*`.
-
-### API key authentication errors
-
-API-key authentication failures return HTTP 401 with a machine-readable `code`:
-
-| Code | Meaning |
-|---|---|
-| `missing` | No Authorization header was supplied. |
-| `malformed` | The Authorization header is not a valid Bearer header. |
-| `unknown` | The key was not recognized; never-issued and unknown keys have the same response. |
-| `revoked` | The recognized key has been revoked. |
-| `expired` | The recognized key has passed its expiry time. |
-
-Unknown keys always receive the same response, regardless of whether the key
-ever existed. Admin-token failures use `admin_unauthorized`.
-
-Admin key creation accepts an optional future ISO date-time in `expiresAt`.
-Omitting it creates a key without an expiry.
-
-```bash
-curl "https://api.example.com/price/XLM/USDC?network=mainnet"
-```
-
-### Data Quality Guarantees
-For formal guarantees on pricing freshness (including the 300s staleness threshold), completeness (venue diversity and outlier filtering), precision (PostgreSQL Decimal(36,18) and negotiated decimal strings), venue inclusion across SDEX and AMMs, and deterministic violation semantics, see [`docs/data-quality.md`](docs/data-quality.md).
-
-### GraphQL
-Available at `/graphql` with GraphiQL IDE at `/graphiql`. Real-time price
-streaming is available via the `priceUpdated` [subscription](#graphql-subscriptions-live-prices).
-
-For complete GraphQL schema documentation, all queries with runnable `curl` examples, WebSocket `graphql-transport-ws` handshake specifications, and an explicit comparison against the REST surface, see [`docs/graphql.md`](docs/graphql.md).
-
-```graphql
-query {
-  getPrice(assetA: "XLM", assetB: "USDC") {
-    price
-    bestRoute
-    vwap1h
-    volume24h
-    priceChange24h
-  }
-  getBestRoute(assetA: "XLM", assetB: "USDC", amount: 500) {
-    route
-    sdexPrice
-    ammPrice
-    estimatedOutput
-    slippagePct
-    recommendation
-  }
-}
-```
-
-#### Schema Definition & SDL Artifact
-The GraphQL schema is exported as a canonical Schema Definition Language (SDL) artifact committed at [`schema.graphql`](schema.graphql).
-
-- **Location**: [`schema.graphql`](schema.graphql)
-- **Regenerate / Refresh**:
-  ```bash
-  npm run graphql:schema:gen
-  ```
-- **Drift Guard & Validation**: CI runs `src/__tests__/graphqlSchemaDrift.test.ts` to assert that `schema.graphql` matches the code-defined schema in `src/api/graphql.ts`, guarantees deterministic output, validates SDL syntax for client generators, and detects breaking schema changes.
-
-
-## Observability
-
-Prometheus metrics are exposed on `GET /metrics` (public, no API key required).
-The MCP server is a separate process with its own `GET /metrics` on its own
-port, and that one does require its bearer token — see
-[MCP server](#mcp-server).
-
-Alongside the ingestion and database metrics, Lens exports HTTP request,
-latency, authentication and rate-limit signals:
-
-| Metric | Type | Labels |
-|---|---|---|
-| `http_requests_total` | Counter | `method`, `route`, `status_class` |
-| `http_request_duration_seconds` | Histogram | `method`, `route` |
-| `api_key_auth_failures_total` | Counter | `reason` |
-| `admin_auth_failures_total` | Counter | — |
-| `rate_limit_rejections_total` | Counter | `scope` |
-| `global_shed_requests_total` | Counter | — |
-
-`route` is the matched route **template** (`/price/:assetA/:assetB`), never the
-resolved URL, so the number of time series stays bounded no matter how many
-distinct assets are queried. `status_class` is `2xx`/`4xx`/`5xx` rather than the
-exact code, for the same reason.
-
-```promql
-# Request rate
-sum(rate(http_requests_total[5m])) by (route)
-
-# Error rate
-sum(rate(http_requests_total{status_class="5xx"}[5m]))
-  / sum(rate(http_requests_total[5m]))
-
-# p95 latency
-histogram_quantile(0.95,
-  sum(rate(http_request_duration_seconds_bucket[5m])) by (le))
-```
-
-See [`docs/http-metrics.md`](docs/http-metrics.md) for the full label reference,
-the bucket rationale and suggested alerting rules.
-
-The websocket stream carries its own signals — `ws_clients_total`,
-`ws_messages_sent_total`, `ws_messages_dropped_total`, `ws_clients_dropped_total`
-and `ws_buffered_bytes` — which exist to make slow subscribers visible instead
-of silent. See [`docs/websocket-backpressure.md`](docs/websocket-backpressure.md).
-
-The ingestion metrics are labelled by `network` as well, so a dual-network
-deployment reports each network separately:
-
-| Metric | Type | Labels |
-|---|---|---|
-| `trades_ingested_total` | Counter | `pair`, `network` |
-| `amm_snapshots_total` | Counter | `pool`, `network` |
-| `price_snapshots_total` | Counter | `network` |
-| `last_trade_timestamp` | Gauge | `pair`, `network` |
-
-`last_trade_timestamp` is a gauge, so without the `network` label one network's
-ingester overwrites the other's value for the same pair — which would make the
-staleness signal silently unusable. See
-[`docs/ingest-metrics.md`](docs/ingest-metrics.md) for the cardinality notes
-(`pairs x networks`) and a staleness alert.
-
-### Database Connection Pool & Shared Architecture
-
-> **Important architectural note**: The ingester loops (SDEX, AMM, Soroswap, Snapshot, Aquarius), background workers (retention, partitions), and the HTTP/GraphQL API handlers **run in a single process and share one connection pool**.
-
-Because deployments often scale across multiple instances, total database connections against Postgres equal:
-$$\text{Total Connections} = \text{Instances} \times \text{DB\_POOL\_SIZE} + \text{Superuser/Admin Headroom}$$
-
-Configure `DB_POOL_SIZE` and `DB_POOL_TIMEOUT_MS` appropriately so the aggregate across all running instances stays safely beneath PostgreSQL's `max_connections` (typically 100).
-
-Pool utilisation and exhaustion metrics are exposed on `GET /metrics`:
-- `db_pool_connections_in_use`: Number of active connections checked out.
-- `db_pool_connections_idle`: Number of idle connections ready in pool.
-- `db_pool_connections_waiting`: Requests queued waiting for an available connection.
-- `db_pool_exhaustion_errors_total`: Counter incremented whenever connection acquisition times out. Requests encountering pool exhaustion fail with an explicit `503 Service Unavailable` (`DB_POOL_EXHAUSTED`) rather than generic latency or unhandled timeouts.
-
-### GraphQL Subscriptions (live prices)
-
-Lens exposes a `priceUpdated(pair)` subscription that pushes a message every time
-an ingester (SDEX, Horizon AMM, or Soroswap) records a new price for the pair.
-It runs over the same `/graphql` endpoint using the `graphql-transport-ws`
-protocol, so any [`graphql-ws`](https://github.com/enisdenjo/graphql-ws) client works.
-
-```graphql
-subscription {
-  priceUpdated(pair: "XLM/USDC", network: "mainnet") {
-    pair
-    price
-    ts
-    network
-  }
-}
-```
-
-```bash
-npm install graphql-ws ws
-```
-
-```typescript
-import { createClient } from "graphql-ws";
-import WebSocket from "ws"; // browsers already have WebSocket globally
-
-const client = createClient({
-  url: "ws://localhost:3002/graphql",
-  webSocketImpl: WebSocket, // omit in the browser
-});
-
-// `subscribe` returns an unsubscribe function — call it to close the channel.
-const unsubscribe = client.subscribe(
-  {
-    query: `subscription ($pair: String!, $network: String) {
-      priceUpdated(pair: $pair, network: $network) { pair price ts network }
-    }`,
-    variables: { pair: "XLM/USDC", network: "mainnet" },
-  },
-  {
-    next: ({ data }) => console.log("price:", data.priceUpdated),
-    error: (err) => console.error("subscription error:", err),
-    complete: () => console.log("subscription closed"),
-  },
-);
-
-// Later — stop receiving updates and close the socket cleanly:
-// unsubscribe();
-```
-
-> **`network` is optional but you almost always want it.** Since #117 every
-> enabled network runs its own ingester loop and they all publish to the same
-> stream, so omitting it interleaves testnet and mainnet prices for the same
-> pair. Every message carries its own `network` field, so an omitted argument
-> is safe *if* you read that field — and misleading if you do not.
-
-> **Note:** the `pair` argument is the canonical `pairKey` (alphabetically
-> sorted, e.g. `USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN/XLM`). Use the `listPairs` query to discover
-> the exact keys being indexed. Only the pair you subscribe to is delivered;
-> updates for other pairs are filtered out server-side. For full protocol handshake details and a raw WebSocket implementation, see [`docs/graphql.md`](docs/graphql.md#live-price-subscriptions-graphql-transport-ws).
-
-## MCP server
-
-`npm run mcp:server` starts the Bazaar MCP server ([src/mcp/server.ts](src/mcp/server.ts), wired up in [examples/mcp-server/run.ts](examples/mcp-server/run.ts)). It advertises:
-
-| Tool | What it does | Spends? |
-| --- | --- | --- |
-| `bazaar_search` | Reads a Bazaar base URL's `/discovery/resources` or `/discovery/search?q=` and lists what is available. | No |
-| `paid_call` | Fetches an x402-gated URL and handles the `402 → sign → retry` loop. | **Yes — it signs with a real Stellar key** |
-| `payment_budget` | Reports the configured limits and what is left of today's budget. | No |
-| `lens_get_price` | Reads Lens's own aggregated price for a watched pair. | No |
-
-`payment_budget` appears whenever a spend budget is configured, which the example always sets, and `lens_get_price` only where the server can reach Lens's own price data. Every one of them is served over **either** transport, and the tool list, schemas and error codes are identical whichever you pick. Which transport runs is selected by configuration; **stdio is the default**, so an existing setup needs no changes.
-
-**⚠️ Warning:** the mainnet key signs with real XLM. Read the configuration,
-spending warning, and worked example before running.
-
-The server signs with a real Stellar key, so it needs `MCP_AGENT_SECRET_KEY_TESTNET`
-and `MCP_AGENT_SECRET_KEY_MAINNET` in the environment — keep them in `.env`
-(`run.ts` loads it with `dotenv`) rather than in a shell history line or a
-client config file that gets shared. Never commit them. Optional spend
-controls: `MCP_MAX_PAYMENT_PRICE` (per call, default `$1.00`),
-`MCP_DAILY_SPEND_CEILING` (default `$10.00`) and `MCP_SPEND_STATE_FILE` — the
-running total survives a restart, because a restart does not refund what the
-previous process spent.
-
-Full documentation: [examples/mcp-server/README.md](examples/mcp-server/README.md)
-
-### stdio (default)
-
-For a client that spawns the server itself as a child process — Claude
-Desktop, Cursor, or the runnable [agent example](examples/mcp-server/agent.ts)
-(`npm run mcp:agent`, which prints discovery and a paid call end to end).
-
-```bash
-npm run mcp:server   # reads MCP_TRANSPORT=stdio, talks JSON-RPC on stdin/stdout
-```
-
-Point a client at the command — the keys come from `.env`, so nothing secret
-has to be written into client config. This is the same invocation
-[agent.ts](examples/mcp-server/agent.ts) uses:

-
-Because the process is spawned by the client, there is no port, no token and
-no remote attack surface: whoever can spawn it can spend, so keep it to
-your own machine.
-
-### Streamable HTTP
-
-For a client that connects over the network instead of spawning a process —
-a hosted agent, a shared dev box, a container. Set `MCP_TRANSPORT=http`:
-
-```bash
-# MCP_AGENT_SECRET_KEY_TESTNET / MCP_AGENT_SECRET_KEY_MAINNET live in .env
-export MCP_TRANSPORT=http
-export MCP_HTTP_AUTH_TOKEN="$(openssl rand -hex 32)"   # required, see below
-export MCP_HTTP_HOST=127.0.0.1                   # default
-export MCP_HTTP_PORT=3003                        # default
-export MCP_HTTP_PATH=/mcp                        # default
-npm run mcp:server
-# [mcp-server] Listening at http://127.0.0.1:3003/mcp
-```
-
-**Authentication is mandatory and fails closed.** Without a non-empty
-`MCP_HTTP_AUTH_TOKEN` the process exits before it builds a signer, so an
-unauthenticated remote server with `paid_call` on its tool list can never come
-up. Every request must then carry it as a bearer token; anything else gets a
-JSON-RPC error with `ERR_UNAUTHORIZED` and is rejected before the payment path
-is reached:
-
-```bash
-curl -sS -X POST http://127.0.0.1:3003/mcp \
-  -H "Authorization: Bearer $MCP_HTTP_AUTH_TOKEN" \
-  -H "Content-Type: application/json" \
-  -H "Accept: application/json, text/event-stream" \
-  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
-```
-
-A client connects the same way:
-
-```ts
-import { Client } from '@modelcontextprotocol/sdk/client/index.js';
-import { StreamableHTTPClientTransport } from '@modelcontextprotocol/sdk/client/streamableHttp.js';
-
-const transport = new StreamableHTTPClientTransport(new URL('http://127.0.0.1:3003/mcp'), {
-  requestInit: { headers: { authorization: `Bearer ${process.env.MCP_HTTP_AUTH_TOKEN}` } },
-});
-
-const client = new Client({ name: 'lens-agent', version: '1.0.0' }, { capabilities: {} });
-await client.connect(transport);
-```
-
-Notes for this transport:
-
-- It binds `127.0.0.1` unless you set `MCP_HTTP_HOST` deliberately. Do not
-  expose it on a routable address over plain HTTP: the bearer token and every
-  paid result cross the wire, so terminate TLS in a reverse proxy and forward
-  to loopback.
-- The token is a credential — the bearer who holds it can spend. Keep it out
-  of URLs, logs, and shell history; rotate it if it leaks.
-- Requests are stateless: no `Mcp-Session-Id` is issued and each `POST` is
-  served by a fresh transport, so a client cannot hold a session open across
-  requests. Every MCP message must be a `POST` (`GET` returns `405`, which
-  spec-compliant clients treat as "no server-initiated stream"). Bodies are
-  capped at 1 MiB.
-- The daily spend ceiling is shared across everything this process serves, so
-  one HTTP client cannot spend past a budget another one already used up.
-
-#### Payment spend metrics
-
-What the agent spent is scrapeable from the same listener, at `GET /metrics`,
-guarded by the same bearer token — it is operator data about a key that moves
-money, so there is no anonymous scrape:
-
-```bash
-curl -sS http://127.0.0.1:3003/metrics \
-  -H "Authorization: Bearer $MCP_HTTP_AUTH_TOKEN"
-```
-
-| Metric | Type | Labels |
-| --- | --- | --- |
-| `mcp_payment_attempts_total` | Counter | `host`, `network`, `outcome` |
-| `mcp_payment_amount_usd_total` | Counter | `host`, `network` |
-| `mcp_payment_unquantified_total` | Counter | `host`, `network` |
-
-A refused payment is an attempt (`outcome="failure"`) and adds nothing to
-`mcp_payment_amount_usd_total`. `host` may only be a value from
-`MCP_METRIC_HOSTS` and `network` only one from `MCP_METRIC_NETWORKS` (default
-`stellar:testnet,stellar:pubnet` — the networks this server signs for):
-Prometheus series are permanent, so anything outside an allow-list is reported
-as `unknown` instead of letting one caller mint a time series per URL an agent
-tries. Amounts that are not a USD money string cannot join the USD sum, so they
-are counted in `mcp_payment_unquantified_total` rather than dropped silently.
-Per-payment detail — full URL, transaction hash, asset, error code — is in the
-`MCP_PAYMENT_LEDGER_FILE` audit trail, which keeps the real host whatever the
-allow-list says.
-
-`MCP_HTTP_PATH` cannot be `/metrics`; the process exits at boot rather than
-answering MCP and Prometheus on one path. Under **stdio** there is no listener
-to scrape, so read the running total from the `payment_budget` tool or the
-audit file.
-
-### WebSocket backpressure
-
-`/ws` counts a message as sent only once the socket reports the write completed,
-and bounds what a client that stops reading can cost: past 256 KiB of queued
-bytes updates are coalesced to the newest one, past 1 MiB — or congested for 30s
-— the client is closed with `1013` and counted. A truncated feed is visible in
-`ws_messages_dropped_total` rather than silent, and one slow client cannot affect
-any other. See [`docs/websocket-backpressure.md`](docs/websocket-backpressure.md).
-
-## Usage Examples
-
-Lens gates `/price`, `/pools`, and `/candles` behind x402 micropayments on Stellar (testnet by default). The `/status` endpoint is free.
-
-### 1. Free health check & status monitoring (`/status`)
-
-`/status` provides a structured, comprehensive health contract separating **process health** (runtime container, memory, uptime) from **data health** (ingestion currency, last ledger, ingest lag).
-
-```bash
-curl http://localhost:3002/status
-```
-
-```json
-{
-  "ok": true,
-  "status": "healthy",
-  "network": "testnet",
-  "health": {
-    "process": "healthy",
-    "data": "healthy"
-  },
-  "process": {
-    "uptimeSeconds": 86420,
-    "memoryUsageMb": 18.42,
-    "status": "healthy"
-  },
-  "data": {
-    "lastIndexedLedger": 53842917,
-    "lastProcessedAt": "2026-05-07T18:45:11.220Z",
-    "ingestLagSeconds": 4,
-    "isStale": false
-  },
-  "watchedPairs": ["XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN"],
-  "lastIndexedLedger": 53842917,
-  "lastProcessedAt": "2026-05-07T18:45:11.220Z",
-  "ingestLagSeconds": 4
-}
-```
-
-#### Health Differentiation & Paging Conditions
-- **Process Health vs Data Health:** The HTTP status code distinguishes service availability from data staleness.
-  - `HTTP 200 OK` (`status: "healthy"`): Both process runtime and data feeds are functioning normally.
-  - `HTTP 200 OK` (`status: "degraded"`, `health.data: "stale"`): The API server is healthy and responding, but ingestion lag exceeds 300 seconds. **Do not page engineers for intermittent upstream ledger delays.**
-  - `HTTP 200 OK` (`status: "degraded"`, `health.process: "degraded"`): the port answers but boot has not finished, so not every ingester is running yet. Normal for the first seconds of a deploy — gate rollouts on `/ready`, which stays 503 until boot completes, rather than paging on this.
-  - `HTTP 503 Service Unavailable` (`pagingCondition: "DATABASE_DOWN"`): Critical infrastructure failure (e.g. Postgres is down or unreachable). **Uptime monitors should page on HTTP 503.** The body carries `error: "Database unavailable"` and nothing more — `/status` is public, so the driver's own message (which can contain the host, the user and the connection string) goes to the server log only.
-
-#### Monitoring Configuration Example (Datadog / Prometheus / BetterStack)
-Configure your synthetic monitor / HTTP probe:
-```yaml
-# Prometheus Blackbox / Uptime monitor probe example
-probe:
-  target: "http://lens-api.internal:3002/status?network=mainnet"
-  method: "GET"
-  expect_status: 200
-  alert_conditions:
-    - severity: critical # Page on-call
-      condition: "status_code == 503 || body.pagingCondition == 'DATABASE_DOWN'"
-    - severity: warning  # Slack notification only
-      condition: "body.health.data == 'stale' || body.data.ingestLagSeconds > 300"
-```
-
-### 2. Paid request without `X-PAYMENT` → `402` with payment requirements
-
-```bash
-curl -i http://localhost:3002/price/XLM/USDC
-# HTTP/1.1 402 Payment Required
-# content-type: application/json
-#
-# {
-#   "x402Version": 1,
-#   "accepts": [
-#     {
-#       "scheme": "exact",
-#       "price": "$0.10",
-#       "network": "stellar:testnet",
-#       "payTo": "G...your-oracle-address..."
-#     }
-#   ],
-#   "error": "Payment required",
-#   "description": "Unified SDEX+AMM price with VWAP and best route"
-# }
-```
-
-The `accepts[]` array lists every payment requirement the server will honor. Sign one of them, encode as JSON, base64-encode, and resend with the `X-PAYMENT` header.
-
-### 3. Paid request with `X-PAYMENT` → `200` with price data
-
-```bash
-# X-PAYMENT is base64(JSON(signed payment payload — see @x402/stellar))
-curl -H "X-PAYMENT: $(cat payment.b64)" \
-     http://localhost:3002/price/XLM/USDC
-# {
-#   "assetA": "XLM",
-#   "assetB": "USDC",
-#   "pairKey": "XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN",
-#   "vwap1m": "0.12450000",
-#   "vwap1h": "0.12410000",
-#   "volume24h": "1284390.5500",
-#   "priceChange24h": "0.32",
-#   "bestRoute": "amm",
-#   "lastUpdated": "2026-05-07T18:46:02.114Z"
-# }
-```
-
-### 4. Node.js — automatic payment with `@x402/fetch` + `@x402/stellar`
-
-`@x402/fetch` wraps the native `fetch` so a `402` is intercepted, signed, and retried automatically — your application code looks like a normal request.
-
-```bash
-npm install @x402/fetch @x402/stellar
-```
-
-```typescript
-import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
-import { ExactStellarScheme } from "@x402/stellar/exact/client";
-import { createEd25519Signer } from "@x402/stellar";
-
-// 1. Sign with a Stellar testnet secret (S...). Fund via friendbot first.
-const signer = createEd25519Signer(
-  process.env.STELLAR_SECRET!, // e.g. "SBN...FUNDED..."
-  "stellar:testnet",
-);
-
-// 2. Wrap fetch — `stellar:*` matches both pubnet and testnet.
-const fetchWithPayment = wrapFetchWithPaymentFromConfig(fetch, {
-  schemes: [
-    {
-      network: "stellar:*",
-      client: new ExactStellarScheme(signer),
-    },
-  ],
-});
-
-// 3. Call the gated endpoint. The 402 → sign → 200 dance is automatic.
-const res = await fetchWithPayment("http://localhost:3002/price/XLM/USDC");
-const data = await res.json();
-console.log(`XLM/USDC VWAP-1h: ${data.vwap1h}`);
-```
-
-> **Mainnet:** swap `STELLAR_NETWORK=mainnet` on the server, point the
-> client at `stellar:pubnet`, and supply a custom Soroban RPC URL via
-> `new ExactStellarScheme(signer, { url: "https://your-rpc..." })`.
-> Stellar payments use *ledger-based* expiration (~12 ledgers ≈ 60s),
-> not timestamps.
-
-### 5. GraphQL price query
-
-```bash
-curl -X POST http://localhost:3002/graphql \
-  -H "Content-Type: application/json" \
-  -d '{"query":"{ getPrice(assetA:\"XLM\", assetB:\"USDC\") { price vwap1h volume24h priceChange24h } }"}'
-```
-
-Or interactively at [http://localhost:3002/graphiql](http://localhost:3002/graphiql).
-
-> **Note:** the current `GATED_ROUTES` map in [`src/middleware/x402.ts`](src/middleware/x402.ts) gates `/price`, `/pools`, and `/candles` only — `/graphql` is not gated. If you intend price data from GraphQL to require the same payment as REST, extend `GATED_ROUTES` (or add a per-resolver guard).
-
-## TypeScript Client
-
-A typed TypeScript client is generated from [`openapi.yaml`](openapi.yaml) with
-[`openapi-typescript`](https://github.com/openapi-ts/openapi-typescript) and
-[`openapi-fetch`](https://github.com/openapi-ts/openapi-typescript/tree/main/packages/openapi-fetch).
-It is committed at [`clients/typescript`](clients/typescript) — **no type is
-hand-written**, so a change to the spec is a change to the client.
-
-```bash
-# Regenerate clients/typescript/src/schema.d.ts from the spec
-npm run client:gen
-
-# Type-check the generated client
-npm run client:typecheck
-```
-
-CI runs `npm run client:gen` and fails if the committed client differs from the
-regenerated output, so the client can never drift from `openapi.yaml`.
-
-```typescript
-import { createLensClient } from "./clients/typescript/src/index.js";
-
-const client = createLensClient({ baseUrl: "http://localhost:3002" });
-
-const { data, error } = await client.GET("/price/{assetA}/{assetB}", {
-  params: { path: { assetA: "XLM", assetB: "USDC" } },
-});
-if (error) throw new Error(`request failed: ${error}`);
-
-// `data` is `AggregatedPrice`, derived from the spec.
-console.log(`XLM/USDC vwap1h: ${data?.vwap1h}`);
-```
-
-A runnable version lives in
-[`clients/typescript/src/example.ts`](clients/typescript/src/example.ts); run it
-against a local server with `npx tsx clients/typescript/src/example.ts`.
-
-## Documentation
-Detailed system design and data flow diagrams can be found in the [Architecture Overview](docs/architecture.md).
-Lens also *publishes* prices: [`docs/sep40-oracle-publisher.md`](docs/sep40-oracle-publisher.md) covers the SEP-40 contract in `oracle/contract/`, the deviation-and-interval publication policy in `src/publish/`, deployment, and key handling.
-The API specification is available in [OpenAPI 3.0 format](openapi.yaml) and is auto-published to GitHub Pages at https://miracle656.github.io/lens/openapi.json.
-
-Operators: start with the [Operations runbook](docs/RUNBOOK.md) — what runs, how each external dependency degrades, how to check ingestion health via `/status` and `/metrics`, the known failure modes with their symptoms, and deploy/rollback procedures.
-
-Operational docs: [HTTP metrics](docs/http-metrics.md), [ingest metrics](docs/ingest-metrics.md), [websocket backpressure](docs/websocket-backpressure.md), [health probes](docs/health.md), [GraphQL](docs/graphql.md).
-The MCP server also advertises read-only [resources](docs/mcp-resources.md) — the watched pairs, venues, this OpenAPI document, and service status — each with a stable URI and freshness an agent can cache against.
-
-## Examples
-
-The [oracle relay example](examples/oracle-relay/README.md) shows a minimal Soroban contract plus a Node relay that reads Lens prices and pushes them on chain.
-
-The [price alert bot example](examples/alert-bot/README.md) shows an "if XLM > X notify me" bot built on the WebSocket price stream — see the [cookbook walkthrough](docs/cookbook/alert-bot.md).
-
-## Docker Quickstart
-The fastest way to get Lens running locally is with Docker:
-
-```bash
-# Start Lens, Postgres, and Redis
-docker compose up -d
-
-# Check health
-docker compose ps
-```
-The API will be available at `http://localhost:3002`. Database migrations run automatically on startup.
-
-## Quick Start (Manual)
-
-```bash
-# 1. Start PostgreSQL + Redis
-docker-compose up -d
-
-# 2. Install dependencies
-npm install
-
-# 3. Copy env
-cp .env.example .env
-
-# 4. Apply database migrations
-npm run db:deploy
-
-# 5. Seed the database with fixture data
-npm run seed
-
-# 6. Start dev server
-npm run dev
-```
-
-## Seed & Query
-
-A fresh clone gives an empty database — every price endpoint returns zeros and
-you cannot tell working code from broken code. `npm run seed` writes
-deterministic fixture data so the API is immediately usable.
-
-### What it seeds
-
-| Table | Rows per network | Description |
-|---|---|---|
-| `pair_configs` | 1 | Default pair registration so `/pairs` and `/price` resolve immediately |
-| `price_points` | 36 (24 SDEX + 12 AMM) | Hourly SDEX trades and bi-hourly AMM trades over 24 h |
-| `pool_snapshots` | 6 | AMM pool reserves every 4 h |
-| `price_aggregates` | 49 (12×1m + 12×5m + 24×1h + 1×24h) | Pre-computed OHLCV buckets |
-
-Data is seeded for the default pair on each network:
-- **testnet:** `XLM / USDC:GBBD47IF6LWK7P7MDEVSCWR7DPUWV3NY3DTQEVFL4NAT4AQH3ZLLFLA5`
-- **mainnet:** `XLM / USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN`
-
-### Usage
-
-```bash
-# Seed both networks (default)
-npm run seed
-
-# Seed a single network
-npm run seed -- --network testnet
-npm run seed -- --network mainnet
-```
-
-### Idempotency
-
-The seed guarantees idempotency by **converging to the same deterministic row set**.
-Timestamps are anchored to the current UTC hour (`Math.floor(Date.now() / 3_600_000) * 3_600_000`), keeping fixture data fresh relative to `NOW()` (satisfying service-level queries bounded by 1 h / 24 h intervals).
-
-To prevent duplicate accumulation across runs while keeping timestamps fresh, re-seeding safely cleans up previously seed-owned rows (`where: { id: { startsWith: 'seed-' }, network }`) before inserting the fresh set. Default pair configs use `skipDuplicates: true` on `@@id([network, pairKey])` so existing pairs are preserved.

-return real data:

-
-## Rate Limiting & 429 Handling
-
-Lens enforces rate limits per client IP or authenticated API key to protect system throughput:
-
-| Tier / Endpoint | Window | Limit |
-| :--- | :--- | :--- |
-| **Public Unauthenticated (by IP)** | 1 minute | `100 requests` (`RATE_LIMITS.ipDefault`) |
-| **Authenticated API Keys** | 1 minute | `1,000 requests` (`RATE_LIMITS.authenticatedDefault`) |
-| **Public Health/Monitoring (`/status`)** | 1 minute | `1,000 requests` (`RATE_LIMITS.monitoring`) |
-
-### Handling 429 (Too Many Requests)
-When a client exceeds their allowance, Lens replies with HTTP status `429 Too Many Requests`.
-
-1. **`Retry-After` Header:** Specifies the number of seconds to wait before retrying (e.g., `Retry-After: 42`).
-2. **Standardized Error Body:**
-   ```json
-   {
-     "statusCode": 429,
-     "error": "Too Many Requests",
-     "code": "rate_limited",
-     "message": "Rate limit exceeded, retry in 42 seconds",
-     "retryAfter": 42
-   }
-   ```
-Callers should parse the `Retry-After` header or `retryAfter` field and apply exponential backoff.

-### Deployed smoke check
-
-Run against a real running instance (local, staging or production):
-
-```bash
-SMOKE_MAX_AGE_SECONDS=120 SMOKE_TIMEOUT_MS=8000 npm run smoke -- http://localhost:3002
-```
-
-Validate the smoke checker itself with `npm run test:smoke`.
-
-The check requires public `/status`, `/live` and `/ready`, plus `/price/XLM/USDC`. It uses a
-`graphql-transport-ws` live price subscription at `/graphql`. Both probes must be
-present and healthy — a missing `/ready` fails the run rather than being skipped,
-since a smoke check that silently tolerates an absent probe is how a deployment
-ends up unmonitored while still green. It checks
-indexer and trade freshness, validates price shape, and waits for a real
-subscription event. It fails non-zero, naming the failing check, on timeout,
-stale data, a missing message, or HTTP errors. No synthetic price events are
-generated. On installations where x402 payment gates the price endpoint,
-a normal unauthenticated call receives HTTP 402 and the smoke check fails;
-it never bypasses payment requirements. A quiet pair without any new trades
-will likewise fail the live-message requirement.

+## Quickstart
+
+### REST
+
+```bash
+curl http://localhost:3002/status
+# {
+#   "ok": true,
+#   "network": "testnet",
+#   "watchedPairs": ["XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN"],
+#   "lastIndexedLedger": 53842917,  // illustrative — actual value depends on when /status is queried
+#   "lastProcessedAt": "2026-05-07T18:45:11.220Z",  // illustrative — actual value depends on when /status is queried
+#   "ingestLagSeconds": 4  // illustrative — actual value depends on when /status is queried
+# }
+#
+# /status answers for one network — pass ?network=mainnet (or the
+# x-network header) to check the mainnet indexer instead. ingestLagSeconds is
+# null until that network has ingested, and lastIndexedLedger is null until
+# its SDEX ingester has recorded a trade.
+```
+
+### GraphQL
+
+```bash
+curl -X POST http://localhost:3002/graphql \
+  -H "Content-Type: application/json" \
+  -d '{"query":"{ getPrice(assetA:\"XLM\", assetB:\"USDC\") { price assetA assetB pairKey bestRoute lastUpdated } }"}'

+#     }
+#   }
+# }
+```
+
+### MCP
+
+```bash
+# By default the MCP server speaks over stdin and stdout and listens on no
+# port; MCP_TRANSPORT=http serves Streamable HTTP on MCP_HTTP_PORT instead
+# (see "MCP server" below). Port 3002 is the HTTP API, which knows nothing
+# about MCP either way.
+npm run mcp:server
+
+# To drive it interactively, point the inspector at that command:
+npx @modelcontextprotocol/inspector npm run mcp:server
+# Tools and the keys it needs: examples/mcp-server/README.md
+# [
+#   {
+#     "name": "bazaar_search",
+#     "description": "Search for resources in a Stellar Bazaar node"
+#   },
+#   {
+#     "name": "paid_call",
+#     "description": "Make a paid API call to a Bazaar resource"
+#   }
+# ]
+```
+
+**What Horizon doesn't do:** Horizon's `/trade_aggregations` only covers SDEX. AMM pool prices (derived from reserve ratios) are not aggregated anywhere. Lens fills this gap.

+| GET/POST | `/graphql` | GraphQL query/mutation endpoint (GraphiQL IDE at `/graphiql`, docs: [`docs/graphql.md`](docs/graphql.md)) |
+
+Every non-internal route above has a matching entry in [`openapi.yaml`](openapi.yaml);
+`tests/openapi.test.ts` boots the server and fails if a registered route is
+missing from the spec. Operator-only and non-HTTP routes (`/admin/keys*`,
+`/admin/usage*`, `/admin/webhook-delivery-failures`, `/metrics`, `/ws`, `/graphiql*`) are deliberately excluded via
+the commented allow-list in [`src/openapi/coverage.ts`](src/openapi/coverage.ts).
+In addition, live service responses are verified against their published schemas on a daily schedule (`05:00 UTC`) via `npm run spec:validate-live` — see [docs/live-spec-validation.md](docs/live-spec-validation.md).
+
+The `?network=testnet\|mainnet` query param (or `x-network` header) selects the
+Stellar network. It is validated on every request — an unrecognised value gets a
+`400` — and defaults to this instance's `STELLAR_NETWORK`. Only the routes whose
+spec entry declares a `network` parameter answer for the selected network; the
+ones listed below still read a single instance-wide network.
+
+Per-request today: `/price/:assetA/:assetB` (its VWAP, OHLCV, AMM and
+best-route reads), `/price/:assetA/:assetB/route`, `/price/:assetA/:assetB/depth`, `/book/:assetA/:assetB`,
+`/prices/history`, `/screener`, `/pools`, `/pairs`, `/spreads/:asset`,
+`/volumes/:asset`, `/status`, and the x402 payment `network`/`payTo`. That list
+is the same one `openapi.yaml` declares a `network` parameter on — if they ever
+disagree, the spec is the thing to fix.
+
+`GET /volumes/:asset` also reports the trade count, median trade size, largest
+trade's volume share, and `volumeConcentration`. Concentration is the HHI: the
+sum of squared individual trade volume shares (0 to 1; 1 means one trade
+accounted for all volume). The `provenance` object gives the venues and
+positive-volume sample count used and the total observed sample count
+(including zero-volume rows), plus the latest trade time and its age at the
+response's `endTime`.
+When the window has no trades, or its samples have no positive volume, derived
+size and concentration metrics are `null` and `status` explains why.
+
+Still reading across both networks, and ignoring the parameter:
+`/candles/:assetA/:assetB`, `/price/twap/*`, and `/price/vwap/*`.
+
+### API key authentication errors
+
+API-key authentication failures return HTTP 401 with a machine-readable `code`:
+
+| Code | Meaning |
+|---|---|
+| `missing` | No Authorization header was supplied. |
+| `malformed` | The Authorization header is not a valid Bearer header. |
+| `unknown` | The key was not recognized; never-issued and unknown keys have the same response. |
+| `revoked` | The recognized key has been revoked. |
+| `expired` | The recognized key has passed its expiry time. |
+
+Unknown keys always receive the same response, regardless of whether the key
+ever existed. Admin-token failures use `admin_unauthorized`.
+
+Admin key creation accepts an optional future ISO date-time in `expiresAt`.
+Omitting it creates a key without an expiry.
+
+```bash
+curl "https://api.example.com/price/XLM/USDC?network=mainnet"
+```
+
+### Data Quality Guarantees
+For formal guarantees on pricing freshness (including the 300s staleness threshold), completeness (venue diversity and outlier filtering), precision (PostgreSQL Decimal(36,18) and negotiated decimal strings), venue inclusion across SDEX and AMMs, and deterministic violation semantics, see [`docs/data-quality.md`](docs/data-quality.md).
+
+### GraphQL
+Available at `/graphql` with GraphiQL IDE at `/graphiql`. Real-time price
+streaming is available via the `priceUpdated` [subscription](#graphql-subscriptions-live-prices).
+
+For complete GraphQL schema documentation, all queries with runnable `curl` examples, WebSocket `graphql-transport-ws` handshake specifications, and an explicit comparison against the REST surface, see [`docs/graphql.md`](docs/graphql.md).
+
+```graphql
+query {
+  getPrice(assetA: "XLM", assetB: "USDC") {
+    price
+    bestRoute
+    vwap1h
+    volume24h
+    priceChange24h
+  }
+  getBestRoute(assetA: "XLM", assetB: "USDC", amount: 500) {
+    route
+    sdexPrice
+    ammPrice
+    estimatedOutput
+    slippagePct
+    recommendation
+  }
+}
+```
+
+#### Schema Definition & SDL Artifact
+The GraphQL schema is exported as a canonical Schema Definition Language (SDL) artifact committed at [`schema.graphql`](schema.graphql).
+
+- **Location**: [`schema.graphql`](schema.graphql)
+- **Regenerate / Refresh**:
+  ```bash
+  npm run graphql:schema:gen
+  ```
+- **Drift Guard & Validation**: CI runs `src/__tests__/graphqlSchemaDrift.test.ts` to assert that `schema.graphql` matches the code-defined schema in `src/api/graphql.ts`, guarantees deterministic output, validates SDL syntax for client generators, and detects breaking schema changes.
+
+
+## Observability
+
+Prometheus metrics are exposed on `GET /metrics` (public, no API key required).
+The MCP server is a separate process with its own `GET /metrics` on its own
+port, and that one does require its bearer token — see
+[MCP server](#mcp-server).
+
+Alongside the ingestion and database metrics, Lens exports HTTP request,
+latency, authentication and rate-limit signals:
+
+| Metric | Type | Labels |
+|---|---|---|
+| `http_requests_total` | Counter | `method`, `route`, `status_class` |
+| `http_request_duration_seconds` | Histogram | `method`, `route` |
+| `api_key_auth_failures_total` | Counter | `reason` |
+| `admin_auth_failures_total` | Counter | — |
+| `rate_limit_rejections_total` | Counter | `scope` |
+| `global_shed_requests_total` | Counter | — |
+
+`route` is the matched route **template** (`/price/:assetA/:assetB`), never the
+resolved URL, so the number of time series stays bounded no matter how many
+distinct assets are queried. `status_class` is `2xx`/`4xx`/`5xx` rather than the
+exact code, for the same reason.
+
+```promql
+# Request rate
+sum(rate(http_requests_total[5m])) by (route)
+
+# Error rate
+sum(rate(http_requests_total{status_class="5xx"}[5m]))
+  / sum(rate(http_requests_total[5m]))
+
+# p95 latency
+histogram_quantile(0.95,
+  sum(rate(http_request_duration_seconds_bucket[5m])) by (le))
+```
+
+See [`docs/http-metrics.md`](docs/http-metrics.md) for the full label reference,
+the bucket rationale and suggested alerting rules.
+
+The websocket stream carries its own signals — `ws_clients_total`,
+`ws_messages_sent_total`, `ws_messages_dropped_total`, `ws_clients_dropped_total`
+and `ws_buffered_bytes` — which exist to make slow subscribers visible instead
+of silent. See [`docs/websocket-backpressure.md`](docs/websocket-backpressure.md).
+
+The ingestion metrics are labelled by `network` as well, so a dual-network
+deployment reports each network separately:
+
+| Metric | Type | Labels |
+|---|---|---|
+| `trades_ingested_total` | Counter | `pair`, `network` |
+| `amm_snapshots_total` | Counter | `pool`, `network` |
+| `price_snapshots_total` | Counter | `network` |
+| `last_trade_timestamp` | Gauge | `pair`, `network` |
+
+`last_trade_timestamp` is a gauge, so without the `network` label one network's
+ingester overwrites the other's value for the same pair — which would make the
+staleness signal silently unusable. See
+[`docs/ingest-metrics.md`](docs/ingest-metrics.md) for the cardinality notes
+(`pairs x networks`) and a staleness alert.
+
+### Database Connection Pool & Shared Architecture
+
+> **Important architectural note**: The ingester loops (SDEX, AMM, Soroswap, Snapshot, Aquarius), background workers (retention, partitions), and the HTTP/GraphQL API handlers **run in a single process and share one connection pool**.
+
+Because deployments often scale across multiple instances, total database connections against Postgres equal:
+$$\text{Total Connections} = \text{Instances} \times \text{DB\_POOL\_SIZE} + \text{Superuser/Admin Headroom}$$
+
+Configure `DB_POOL_SIZE` and `DB_POOL_TIMEOUT_MS` appropriately so the aggregate across all running instances stays safely beneath PostgreSQL's `max_connections` (typically 100).
+
+Pool utilisation and exhaustion metrics are exposed on `GET /metrics`:
+- `db_pool_connections_in_use`: Number of active connections checked out.
+- `db_pool_connections_idle`: Number of idle connections ready in pool.
+- `db_pool_connections_waiting`: Requests queued waiting for an available connection.
+- `db_pool_exhaustion_errors_total`: Counter incremented whenever connection acquisition times out. Requests encountering pool exhaustion fail with an explicit `503 Service Unavailable` (`DB_POOL_EXHAUSTED`) rather than generic latency or unhandled timeouts.
+
+### GraphQL Subscriptions (live prices)
+
+Lens exposes a `priceUpdated(pair)` subscription that pushes a message every time
+an ingester (SDEX, Horizon AMM, or Soroswap) records a new price for the pair.
+It runs over the same `/graphql` endpoint using the `graphql-transport-ws`
+protocol, so any [`graphql-ws`](https://github.com/enisdenjo/graphql-ws) client works.
+
+```graphql
+subscription {
+  priceUpdated(pair: "XLM/USDC", network: "mainnet") {
+    pair
+    price
+    ts
+    network
+  }
+}
+```
+
+```bash
+npm install graphql-ws ws
+```
+
+```typescript
+import { createClient } from "graphql-ws";
+import WebSocket from "ws"; // browsers already have WebSocket globally
+
+const client = createClient({
+  url: "ws://localhost:3002/graphql",
+  webSocketImpl: WebSocket, // omit in the browser
+});
+
+// `subscribe` returns an unsubscribe function — call it to close the channel.
+const unsubscribe = client.subscribe(
+  {
+    query: `subscription ($pair: String!, $network: String) {
+      priceUpdated(pair: $pair, network: $network) { pair price ts network }
+    }`,
+    variables: { pair: "XLM/USDC", network: "mainnet" },
+  },
+  {
+    next: ({ data }) => console.log("price:", data.priceUpdated),
+    error: (err) => console.error("subscription error:", err),
+    complete: () => console.log("subscription closed"),
+  },
+);
+
+// Later — stop receiving updates and close the socket cleanly:
+// unsubscribe();
+```
+
+> **`network` is optional but you almost always want it.** Since #117 every
+> enabled network runs its own ingester loop and they all publish to the same
+> stream, so omitting it interleaves testnet and mainnet prices for the same
+> pair. Every message carries its own `network` field, so an omitted argument
+> is safe *if* you read that field — and misleading if you do not.
+
+> **Note:** the `pair` argument is the canonical `pairKey` (alphabetically
+> sorted, e.g. `USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN/XLM`). Use the `listPairs` query to discover
+> the exact keys being indexed. Only the pair you subscribe to is delivered;
+> updates for other pairs are filtered out server-side. For full protocol handshake details and a raw WebSocket implementation, see [`docs/graphql.md`](docs/graphql.md#live-price-subscriptions-graphql-transport-ws).
+
+## MCP server
+
+`npm run mcp:server` starts the Bazaar MCP server ([src/mcp/server.ts](src/mcp/server.ts), wired up in [examples/mcp-server/run.ts](examples/mcp-server/run.ts)). It advertises:
+
+| Tool | What it does | Spends? |
+| --- | --- | --- |
+| `bazaar_search` | Reads a Bazaar base URL's `/discovery/resources` or `/discovery/search?q=` and lists what is available. | No |
+| `paid_call` | Fetches an x402-gated URL and handles the `402 → sign → retry` loop. | **Yes — it signs with a real Stellar key** |
+| `payment_budget` | Reports the configured limits and what is left of today's budget. | No |
+| `lens_get_price` | Reads Lens's own aggregated price for a watched pair. | No |
+
+`payment_budget` appears whenever a spend budget is configured, which the example always sets, and `lens_get_price` only where the server can reach Lens's own price data. Every one of them is served over **either** transport, and the tool list, schemas and error codes are identical whichever you pick. Which transport runs is selected by configuration; **stdio is the default**, so an existing setup needs no changes.
+
+**⚠️ Warning:** the mainnet key signs with real XLM. Read the configuration,
+spending warning, and worked example before running.
+
+The server signs with a real Stellar key, so it needs `MCP_AGENT_SECRET_KEY_TESTNET`
+and `MCP_AGENT_SECRET_KEY_MAINNET` in the environment — keep them in `.env`
+(`run.ts` loads it with `dotenv`) rather than in a shell history line or a
+client config file that gets shared. Never commit them. Optional spend
+controls: `MCP_MAX_PAYMENT_PRICE` (per call, default `$1.00`),
+`MCP_DAILY_SPEND_CEILING` (default `$10.00`) and `MCP_SPEND_STATE_FILE` — the
+running total survives a restart, because a restart does not refund what the
+previous process spent.
+
+Full documentation: [examples/mcp-server/README.md](examples/mcp-server/README.md)
+
+### stdio (default)
+
+For a client that spawns the server itself as a child process — Claude
+Desktop, Cursor, or the runnable [agent example](examples/mcp-server/agent.ts)
+(`npm run mcp:agent`, which prints discovery and a paid call end to end).
+
+```bash
+npm run mcp:server   # reads MCP_TRANSPORT=stdio, talks JSON-RPC on stdin/stdout
+```
+
+Point a client at the command — the keys come from `.env`, so nothing secret
+has to be written into client config. This is the same invocation
+[agent.ts](examples/mcp-server/agent.ts) uses:
+
+```json
+{
+  "mcpServers": {
+    "lens-bazaar": {
+      "command": "npx",
+      "args": ["tsx", "examples/mcp-server/run.ts"]
+    }
+  }
+}
+```
+
+Because the process is spawned by the client, there is no port, no token and
+no remote attack surface: whoever can spawn it can spend, so keep it to
+your own machine.
+
+### Streamable HTTP
+
+For a client that connects over the network instead of spawning a process —
+a hosted agent, a shared dev box, a container. Set `MCP_TRANSPORT=http`:
+
+```bash
+# MCP_AGENT_SECRET_KEY_TESTNET / MCP_AGENT_SECRET_KEY_MAINNET live in .env
+export MCP_TRANSPORT=http
+export MCP_HTTP_AUTH_TOKEN="$(openssl rand -hex 32)"   # required, see below
+export MCP_HTTP_HOST=127.0.0.1                   # default
+export MCP_HTTP_PORT=3003                        # default
+export MCP_HTTP_PATH=/mcp                        # default
+npm run mcp:server
+# [mcp-server] Listening at http://127.0.0.1:3003/mcp
+```
+
+**Authentication is mandatory and fails closed.** Without a non-empty
+`MCP_HTTP_AUTH_TOKEN` the process exits before it builds a signer, so an
+unauthenticated remote server with `paid_call` on its tool list can never come
+up. Every request must then carry it as a bearer token; anything else gets a
+JSON-RPC error with `ERR_UNAUTHORIZED` and is rejected before the payment path
+is reached:
+
+```bash
+curl -sS -X POST http://127.0.0.1:3003/mcp \
+  -H "Authorization: Bearer $MCP_HTTP_AUTH_TOKEN" \
+  -H "Content-Type: application/json" \
+  -H "Accept: application/json, text/event-stream" \
+  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
+```
+
+A client connects the same way:
+
+```ts
+import { Client } from '@modelcontextprotocol/sdk/client/index.js';
+import { StreamableHTTPClientTransport } from '@modelcontextprotocol/sdk/client/streamableHttp.js';
+
+const transport = new StreamableHTTPClientTransport(new URL('http://127.0.0.1:3003/mcp'), {
+  requestInit: { headers: { authorization: `Bearer ${process.env.MCP_HTTP_AUTH_TOKEN}` } },
+});
+
+const client = new Client({ name: 'lens-agent', version: '1.0.0' }, { capabilities: {} });
+await client.connect(transport);
+```
+
+Notes for this transport:
+
+- It binds `127.0.0.1` unless you set `MCP_HTTP_HOST` deliberately. Do not
+  expose it on a routable address over plain HTTP: the bearer token and every
+  paid result cross the wire, so terminate TLS in a reverse proxy and forward
+  to loopback.
+- The token is a credential — the bearer who holds it can spend. Keep it out
+  of URLs, logs, and shell history; rotate it if it leaks.
+- Requests are stateless: no `Mcp-Session-Id` is issued and each `POST` is
+  served by a fresh transport, so a client cannot hold a session open across
+  requests. Every MCP message must be a `POST` (`GET` returns `405`, which
+  spec-compliant clients treat as "no server-initiated stream"). Bodies are
+  capped at 1 MiB.
+- The daily spend ceiling is shared across everything this process serves, so
+  one HTTP client cannot spend past a budget another one already used up.
+
+#### Payment spend metrics
+
+What the agent spent is scrapeable from the same listener, at `GET /metrics`,
+guarded by the same bearer token — it is operator data about a key that moves
+money, so there is no anonymous scrape:
+
+```bash
+curl -sS http://127.0.0.1:3003/metrics \
+  -H "Authorization: Bearer $MCP_HTTP_AUTH_TOKEN"
+```
+
+| Metric | Type | Labels |
+| --- | --- | --- |
+| `mcp_payment_attempts_total` | Counter | `host`, `network`, `outcome` |
+| `mcp_payment_amount_usd_total` | Counter | `host`, `network` |
+| `mcp_payment_unquantified_total` | Counter | `host`, `network` |
+
+A refused payment is an attempt (`outcome="failure"`) and adds nothing to
+`mcp_payment_amount_usd_total`. `host` may only be a value from
+`MCP_METRIC_HOSTS` and `network` only one from `MCP_METRIC_NETWORKS` (default
+`stellar:testnet,stellar:pubnet` — the networks this server signs for):
+Prometheus series are permanent, so anything outside an allow-list is reported
+as `unknown` instead of letting one caller mint a time series per URL an agent
+tries. Amounts that are not a USD money string cannot join the USD sum, so they
+are counted in `mcp_payment_unquantified_total` rather than dropped silently.
+Per-payment detail — full URL, transaction hash, asset, error code — is in the
+`MCP_PAYMENT_LEDGER_FILE` audit trail, which keeps the real host whatever the
+allow-list says.
+
+`MCP_HTTP_PATH` cannot be `/metrics`; the process exits at boot rather than
+answering MCP and Prometheus on one path. Under **stdio** there is no listener
+to scrape, so read the running total from the `payment_budget` tool or the
+audit file.
+
+### WebSocket backpressure
+
+`/ws` counts a message as sent only once the socket reports the write completed,
+and bounds what a client that stops reading can cost: past 256 KiB of queued
+bytes updates are coalesced to the newest one, past 1 MiB — or congested for 30s
+— the client is closed with `1013` and counted. A truncated feed is visible in
+`ws_messages_dropped_total` rather than silent, and one slow client cannot affect
+any other. See [`docs/websocket-backpressure.md`](docs/websocket-backpressure.md).
+
+## Usage Examples
+
+Lens gates `/price`, `/pools`, and `/candles` behind x402 micropayments on Stellar (testnet by default). The `/status` endpoint is free.
+
+### 1. Free health check & status monitoring (`/status`)
+
+`/status` provides a structured, comprehensive health contract separating **process health** (runtime container, memory, uptime) from **data health** (ingestion currency, last ledger, ingest lag).
+
+```bash
+curl http://localhost:3002/status
+```
+
+```json
+{
+  "ok": true,
+  "status": "healthy",
+  "network": "testnet",
+  "health": {
+    "process": "healthy",
+    "data": "healthy"
+  },
+  "process": {
+    "uptimeSeconds": 86420,
+    "memoryUsageMb": 18.42,
+    "status": "healthy"
+  },
+  "data": {
+    "lastIndexedLedger": 53842917,
+    "lastProcessedAt": "2026-05-07T18:45:11.220Z",
+    "ingestLagSeconds": 4,
+    "isStale": false
+  },
+  "watchedPairs": ["XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN"],
+  "lastIndexedLedger": 53842917,
+  "lastProcessedAt": "2026-05-07T18:45:11.220Z",
+  "ingestLagSeconds": 4
+}
+```
+
+#### Health Differentiation & Paging Conditions
+- **Process Health vs Data Health:** The HTTP status code distinguishes service availability from data staleness.
+  - `HTTP 200 OK` (`status: "healthy"`): Both process runtime and data feeds are functioning normally.
+  - `HTTP 200 OK` (`status: "degraded"`, `health.data: "stale"`): The API server is healthy and responding, but ingestion lag exceeds 300 seconds. **Do not page engineers for intermittent upstream ledger delays.**
+  - `HTTP 200 OK` (`status: "degraded"`, `health.process: "degraded"`): the port answers but boot has not finished, so not every ingester is running yet. Normal for the first seconds of a deploy — gate rollouts on `/ready`, which stays 503 until boot completes, rather than paging on this.
+  - `HTTP 503 Service Unavailable` (`pagingCondition: "DATABASE_DOWN"`): Critical infrastructure failure (e.g. Postgres is down or unreachable). **Uptime monitors should page on HTTP 503.** The body carries `error: "Database unavailable"` and nothing more — `/status` is public, so the driver's own message (which can contain the host, the user and the connection string) goes to the server log only.
+
+#### Monitoring Configuration Example (Datadog / Prometheus / BetterStack)
+Configure your synthetic monitor / HTTP probe:
+```yaml
+# Prometheus Blackbox / Uptime monitor probe example
+probe:
+  target: "http://lens-api.internal:3002/status?network=mainnet"
+  method: "GET"
+  expect_status: 200
+  alert_conditions:
+    - severity: critical # Page on-call
+      condition: "status_code == 503 || body.pagingCondition == 'DATABASE_DOWN'"
+    - severity: warning  # Slack notification only
+      condition: "body.health.data == 'stale' || body.data.ingestLagSeconds > 300"
+```
+
+### 2. Paid request without `X-PAYMENT` → `402` with payment requirements
+
+```bash
+curl -i http://localhost:3002/price/XLM/USDC
+# HTTP/1.1 402 Payment Required
+# content-type: application/json
+#
+# {
+#   "x402Version": 1,
+#   "accepts": [
+#     {
+#       "scheme": "exact",
+#       "price": "$0.10",
+#       "network": "stellar:testnet",
+#       "payTo": "G...your-oracle-address..."
+#     }
+#   ],
+#   "error": "Payment required",
+#   "description": "Unified SDEX+AMM price with VWAP and best route"
+# }
+```
+
+The `accepts[]` array lists every payment requirement the server will honor. Sign one of them, encode as JSON, base64-encode, and resend with the `X-PAYMENT` header.
+
+### 3. Paid request with `X-PAYMENT` → `200` with price data
+
+```bash
+# X-PAYMENT is base64(JSON(signed payment payload — see @x402/stellar))
+curl -H "X-PAYMENT: $(cat payment.b64)" \
+     http://localhost:3002/price/XLM/USDC
+# {
+#   "assetA": "XLM",
+#   "assetB": "USDC",
+#   "pairKey": "XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN",
+#   "vwap1m": "0.12450000",
+#   "vwap1h": "0.12410000",
+#   "volume24h": "1284390.5500",
+#   "priceChange24h": "0.32",
+#   "bestRoute": "amm",
+#   "lastUpdated": "2026-05-07T18:46:02.114Z"
+# }
+```
+
+### 4. Node.js — automatic payment with `@x402/fetch` + `@x402/stellar`
+
+`@x402/fetch` wraps the native `fetch` so a `402` is intercepted, signed, and retried automatically — your application code looks like a normal request.
+
+```bash
+npm install @x402/fetch @x402/stellar
+```
+
+```typescript
+import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
+import { ExactStellarScheme } from "@x402/stellar/exact/client";
+import { createEd25519Signer } from "@x402/stellar";
+
+// 1. Sign with a Stellar testnet secret (S...). Fund via friendbot first.
+const signer = createEd25519Signer(
+  process.env.STELLAR_SECRET!, // e.g. "SBN...FUNDED..."
+  "stellar:testnet",
+);
+
+// 2. Wrap fetch — `stellar:*` matches both pubnet and testnet.
+const fetchWithPayment = wrapFetchWithPaymentFromConfig(fetch, {
+  schemes: [
+    {
+      network: "stellar:*",
+      client: new ExactStellarScheme(signer),
+    },
+  ],
+});
+
+// 3. Call the gated endpoint. The 402 → sign → 200 dance is automatic.
+const res = await fetchWithPayment("http://localhost:3002/price/XLM/USDC");
+const data = await res.json();
+console.log(`XLM/USDC VWAP-1h: ${data.vwap1h}`);
+```
+
+> **Mainnet:** swap `STELLAR_NETWORK=mainnet` on the server, point the
+> client at `stellar:pubnet`, and supply a custom Soroban RPC URL via
+> `new ExactStellarScheme(signer, { url: "https://your-rpc..." })`.
+> Stellar payments use *ledger-based* expiration (~12 ledgers ≈ 60s),
+> not timestamps.
+
+### 5. GraphQL price query
+
+```bash
+curl -X POST http://localhost:3002/graphql \
+  -H "Content-Type: application/json" \
+  -d '{"query":"{ getPrice(assetA:\"XLM\", assetB:\"USDC\") { price vwap1h volume24h priceChange24h } }"}'
+```
+
+Or interactively at [http://localhost:3002/graphiql](http://localhost:3002/graphiql).
+
+> **Note:** the current `GATED_ROUTES` map in [`src/middleware/x402.ts`](src/middleware/x402.ts) gates `/price`, `/pools`, and `/candles` only — `/graphql` is not gated. If you intend price data from GraphQL to require the same payment as REST, extend `GATED_ROUTES` (or add a per-resolver guard).
+
+## TypeScript Client
+
+A typed TypeScript client is generated from [`openapi.yaml`](openapi.yaml) with
+[`openapi-typescript`](https://github.com/openapi-ts/openapi-typescript) and
+[`openapi-fetch`](https://github.com/openapi-ts/openapi-typescript/tree/main/packages/openapi-fetch).
+It is committed at [`clients/typescript`](clients/typescript) — **no type is
+hand-written**, so a change to the spec is a change to the client.
+
+```bash
+# Regenerate clients/typescript/src/schema.d.ts from the spec
+npm run client:gen
+
+# Type-check the generated client
+npm run client:typecheck
+```
+
+CI runs `npm run client:gen` and fails if the committed client differs from the
+regenerated output, so the client can never drift from `openapi.yaml`.
+
+```typescript
+import { createLensClient } from "./clients/typescript/src/index.js";
+
+const client = createLensClient({ baseUrl: "http://localhost:3002" });
+
+const { data, error } = await client.GET("/price/{assetA}/{assetB}", {
+  params: { path: { assetA: "XLM", assetB: "USDC" } },
+});
+if (error) throw new Error(`request failed: ${error}`);
+
+// `data` is `AggregatedPrice`, derived from the spec.
+console.log(`XLM/USDC vwap1h: ${data?.vwap1h}`);
+```
+
+A runnable version lives in
+[`clients/typescript/src/example.ts`](clients/typescript/src/example.ts); run it
+against a local server with `npx tsx clients/typescript/src/example.ts`.
+
+## Documentation
+Detailed system design and data flow diagrams can be found in the [Architecture Overview](docs/architecture.md).
+Lens also *publishes* prices: [`docs/sep40-oracle-publisher.md`](docs/sep40-oracle-publisher.md) covers the SEP-40 contract in `oracle/contract/`, the deviation-and-interval publication policy in `src/publish/`, deployment, and key handling.
+The API specification is available in [OpenAPI 3.0 format](openapi.yaml) and is auto-published to GitHub Pages at https://miracle656.github.io/lens/openapi.json.
+
+Operators: start with the [Operations runbook](docs/RUNBOOK.md) — what runs, how each external dependency degrades, how to check ingestion health via `/status` and `/metrics`, the known failure modes with their symptoms, and deploy/rollback procedures.
+
+Operational docs: [HTTP metrics](docs/http-metrics.md), [ingest metrics](docs/ingest-metrics.md), [websocket backpressure](docs/websocket-backpressure.md), [health probes](docs/health.md), [GraphQL](docs/graphql.md).
+The MCP server also advertises read-only [resources](docs/mcp-resources.md) — the watched pairs, venues, this OpenAPI document, and service status — each with a stable URI and freshness an agent can cache against.
+
+## Examples
+
+The [oracle relay example](examples/oracle-relay/README.md) shows a minimal Soroban contract plus a Node relay that reads Lens prices and pushes them on chain.
+
+The [price alert bot example](examples/alert-bot/README.md) shows an "if XLM > X notify me" bot built on the WebSocket price stream — see the [cookbook walkthrough](docs/cookbook/alert-bot.md).
+
+## Docker Quickstart
+The fastest way to get Lens running locally is with Docker:
+
+```bash
+# Start Lens, Postgres, and Redis
+docker compose up -d
+
+# Check health
+docker compose ps
+```
+The API will be available at `http://localhost:3002`. Database migrations run automatically on startup.
+
+## Quick Start (Manual)
+
+```bash
+# 1. Start PostgreSQL + Redis
+docker-compose up -d
+
+# 2. Install dependencies
+npm install
+
+# 3. Copy env
+cp .env.example .env
+
+# 4. Apply database migrations
+npm run db:deploy
+
+# 5. Seed the database with fixture data
+npm run seed
+
+# 6. Start dev server
+npm run dev
+```
+
+## Seed & Query
+
+A fresh clone gives an empty database — every price endpoint returns zeros and
+you cannot tell working code from broken code. `npm run seed` writes
+deterministic fixture data so the API is immediately usable.
+
+### What it seeds
+
+| Table | Rows per network | Description |
+|---|---|---|
+| `pair_configs` | 1 | Default pair registration so `/pairs` and `/price` resolve immediately |
+| `price_points` | 36 (24 SDEX + 12 AMM) | Hourly SDEX trades and bi-hourly AMM trades over 24 h |
+| `pool_snapshots` | 6 | AMM pool reserves every 4 h |
+| `price_aggregates` | 49 (12×1m + 12×5m + 24×1h + 1×24h) | Pre-computed OHLCV buckets |
+
+Data is seeded for the default pair on each network:
+- **testnet:** `XLM / USDC:GBBD47IF6LWK7P7MDEVSCWR7DPUWV3NY3DTQEVFL4NAT4AQH3ZLLFLA5`
+- **mainnet:** `XLM / USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN`
+
+### Usage
+
+```bash
+# Seed both networks (default)
+npm run seed
+
+# Seed a single network
+npm run seed -- --network testnet
+npm run seed -- --network mainnet
+```
+
+### Idempotency
+
+The seed guarantees idempotency by **converging to the same deterministic row set**.
+Timestamps are anchored to the current UTC hour (`Math.floor(Date.now() / 3_600_000) * 3_600_000`), keeping fixture data fresh relative to `NOW()` (satisfying service-level queries bounded by 1 h / 24 h intervals).
+
+To prevent duplicate accumulation across runs while keeping timestamps fresh, re-seeding safely cleans up previously seed-owned rows (`where: { id: { startsWith: 'seed-' }, network }`) before inserting the fresh set. Default pair configs use `skipDuplicates: true` on `@@id([network, pairKey])` so existing pairs are preserved.
+

+```
+
+### Verify with the API
+
+After seeding, start the server (`npm run dev`) and confirm the endpoints
+return real data:
+
+```bash
+# /pairs — lists watched pairs with latest price
+curl -s http://localhost:3002/pairs | jq '.pairs[0]'
+# {
+#   "pairKey": "USDC:GBBD47IF6LWK7P7MDEVSCWR7DPUWV3NY3DTQEVFL4NAT4AQH3ZLLFLA5/XLM",
+#   "assetA": { "code": "XLM", "issuer": null },
+#   "assetB": { "code": "USDC", "issuer": "GBBD47IF6LWK7P7MDEVSCWR7DPUWV3NY3DTQEVFL4NAT4AQH3ZLLFLA5" },
+#   "latestPrice": 0.11906825,
+#   "lastUpdated": "<seeded-anchor-timestamp>"
+# }
+
+# /pools — lists AMM pool snapshots
+curl -s http://localhost:3002/pools | jq '.pools[0]'
+# {
+#   "pool_id": "65c24738ce0ba076fd4f4d3b66618681ca1f9e9d78c95bb8db3a684a82bb3ee0",
+#   "asset_a": "XLM",

+#   "spot_price": 0.12,
+#   "fee_bp": 30,
+#   "timestamp": "<seeded-anchor-timestamp>"
+# }
+
+# /price/:assetA/:assetB — aggregated VWAP + best route
+curl -s http://localhost:3002/price/XLM/USDC | jq '{price, ammPrice, lastUpdated}'
+# {
+#   "price": 0.11906825,
+#   "ammPrice": 0.12,
+#   "lastUpdated": "<request-timestamp>"
+# }
+```
+

+
+
+## Rate Limiting & 429 Handling
+
+Lens enforces rate limits per client IP or authenticated API key to protect system throughput:
+
+| Tier / Endpoint | Window | Limit |
+| :--- | :--- | :--- |
+| **Public Unauthenticated (by IP)** | 1 minute | `100 requests` (`RATE_LIMITS.ipDefault`) |
+| **Authenticated API Keys** | 1 minute | `1,000 requests` (`RATE_LIMITS.authenticatedDefault`) |
+| **Public Health/Monitoring (`/status`)** | 1 minute | `1,000 requests` (`RATE_LIMITS.monitoring`) |
+
+### Handling 429 (Too Many Requests)
+When a client exceeds their allowance, Lens replies with HTTP status `429 Too Many Requests`.
+
+1. **`Retry-After` Header:** Specifies the number of seconds to wait before retrying (e.g., `Retry-After: 42`).
+2. **Standardized Error Body:**
+   ```json
+   {
+     "statusCode": 429,
+     "error": "Too Many Requests",
+     "code": "rate_limited",
+     "message": "Rate limit exceeded, retry in 42 seconds",
+     "retryAfter": 42
+   }
+   ```
+Callers should parse the `Retry-After` header or `retryAfter` field and apply exponential backoff.
+

+### Deployed smoke check
+
+Run against a real running instance (local, staging or production):
+
+```bash
+SMOKE_MAX_AGE_SECONDS=120 SMOKE_TIMEOUT_MS=8000 npm run smoke -- http://localhost:3002
+```
+
+Validate the smoke checker itself with `npm run test:smoke`.
+
+The check requires public `/status`, `/live` and `/ready`, plus `/price/XLM/USDC`. It uses a
+`graphql-transport-ws` live price subscription at `/graphql`. Both probes must be
+present and healthy — a missing `/ready` fails the run rather than being skipped,
+since a smoke check that silently tolerates an absent probe is how a deployment
+ends up unmonitored while still green. It checks
+indexer and trade freshness, validates price shape, and waits for a real
+subscription event. It fails non-zero, naming the failing check, on timeout,
+stale data, a missing message, or HTTP errors. No synthetic price events are
+generated. On installations where x402 payment gates the price endpoint,
+a normal unauthenticated call receives HTTP 402 and the smoke check fails;
+it never bypasses payment requirements. A quiet pair without any new trades
+will likewise fail the live-message requirement.

-# Mainnet Deployment Guide (Render + UptimeRobot + Neon + external RPC)
-
-This runbook walks through running a **mainnet** Lens node on Render, kept
-awake by UptimeRobot, backed by a managed Postgres (Neon) and an external
-Soroban RPC provider.
-
-> **No secrets or keys are committed anywhere in this guide.** Every credential
-> below is a placeholder — set the real values in your Render dashboard / host
-> environment only.
-
-## Why mainnet is different from testnet
-
-Lens is already closer to mainnet than testnet out of the box: its Soroswap
-factory and Aquarius defaults are **mainnet** addresses. The Reflector oracle
-has no built-in default — supply `REFLECTOR_CONTRACT_ID_MAINNET` from
-[reflector.network](https://reflector.network) to enable it. To point a node at
-mainnet you mostly need to flip the network passphrase, Horizon/RPC URLs and
-set mainnet `WATCHED_PAIRS`.
-
-Two things have no free mainnet equivalent:
-
-- **Soroban RPC** — there is no free public mainnet Soroban RPC. You must bring
-  your own provider (see [RPC provider](#rpc-provider)).
-- **Render free Postgres** — it is **deleted after 90 days**. Use Neon or
-  another managed Postgres for any durable deployment.
-
-## Architecture
-
-```
-UptimeRobot ──GET /status──▶ Render web service (Lens)
-                                  │
-                                  ├── external Soroban RPC provider (RPC_URL)
-                                  ├── Horizon (https://horizon.stellar.org)
-                                  └── Neon Postgres (DATABASE_URL)
-                                  └── Redis (REDIS_URL)
-```
-
-- **Compute:** Render web service (free tier OK for a single node).
-- **Keep-alive:** UptimeRobot pings `/status` every 5 minutes so the free web
-  service never sleeps.
-- **Database:** Neon (or any managed Postgres) — **never** Render free Postgres.
-- **Cache/queues:** Redis (managed, e.g. Render Redis or Upstash).
-
-## Env matrix
-
-| Var | testnet | mainnet |
-|-----|---------|---------|
-| `STELLAR_NETWORK` | `testnet` | `mainnet` |
-| `HORIZON_URL` | `https://horizon-testnet.stellar.org` | `https://horizon.stellar.org` |
-| `RPC_URL` | `https://soroban-testnet.stellar.org` | external provider — **placeholder only** (see below) |
-| `NETWORK_PASSPHRASE` | `Test SDF Network ; September 2015` | `Public Global Stellar Network ; September 2015` |
-| `SOROSWAP_FACTORY_ADDRESS` | `CDP3HMUH6SMS3S7NPGNDJLULCOXXEPSHY4JKUKMBNQMATHDHWXRRJTBY` | `CA4HEQTL2WPEUYKYKCDOHCDNIV4QHNJ7EL4J4NQ6VADP7SYHVRYZ7AW2` |
-| `REFLECTOR_CONTRACT_ID` | *(empty)* | *(required to enable the oracle — copy from reflector.network)* |
-| `WATCHED_PAIRS` | testnet USDC issuer | mainnet USDC issuer |
-| `DATABASE_URL` | testnet DB | **separate** mainnet DB |
-| `REDIS_URL` | testnet Redis | **separate** mainnet Redis |
-
-> Lens resolves each field in this priority order: paired var
-> (`HORIZON_URL_MAINNET`) → generic var (`HORIZON_URL`) → built-in default.
-> Prefer the paired `_MAINNET` / `_TESTNET` vars so both networks can coexist
-> in one env file.
-
-### Mainnet USDC issuer
-
-The mainnet `WATCHED_PAIRS` uses the mainnet USDC issuer:
-
-```
-WATCHED_PAIRS_MAINNET=XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN
-```
-
-## RPC provider
-
-Mainnet has **no free Soroban RPC**. You must provision one from a provider
-(e.g. a hosted Soroban RPC service, a self-hosted `soroban-rpc` node, or a
-third-party RPC gateway). Set the endpoint in the host environment only:
-
-```
-RPC_URL_MAINNET=https://your-provider.example.com/soroban-rpc   # placeholder
-```
-
-Never commit a real provider URL or API key to the repo.
-
-## Render keep-alive (UptimeRobot)
-
-Render **free web services sleep** after ~15 minutes of inactivity. Because
-Lens is an indexer that must keep ingesting, you need a keep-alive:
-
-1. Deploy the Lens image as a Render **web service**.
-2. Create an UptimeRobot monitor that hits `GET /status` every **5 minutes**.
-   `/status` is public (no API key required) and returns indexer health.
-3. Each ping wakes the service and keeps it running.
-
-> **750 instance-hours/month free cap.** A single always-on free instance uses
-> 24 × 31 ≈ 744 hours/month — right at the cap. If you also run a testnet node,
-> either run it on-demand, on a second account, or upgrade to a paid instance.
-> See [Running testnet + mainnet side-by-side](#running-testnet--mainnet-side-by-side).
-
-## Database durability (Neon / managed Postgres)
-
-**Do not use Render's free Postgres for mainnet** — it is **deleted after
-90 days**. Use Neon or another managed Postgres with:
-
-- Automatic backups / point-in-time recovery.
-- A dedicated database per network.
-
-Lens is an aggregator, so the DB is also re-derivable by re-ingesting from
-chain — but a nightly `pg_dump` makes restores fast. See the
-[backup & restore runbook](../../issues/119) (L053) for the nightly `pg_dump`
-workflow and restore procedure.
-
-## Running testnet + mainnet side-by-side
-
-Run **two separate deployments** (same image, one env set each). Give each
-network its **own** database and Redis: every row now carries a `network`
-discriminator (#114), but separate stores keep the two deployments — and any
-read path not yet network-scoped — from pooling networks.

-| `REDIS_URL` | `redis://…testnet…` | `redis://…mainnet…` |

-## Step-by-step
-
-1. **Provision the database.** Create a Neon project (or your managed Postgres)
-   and a dedicated database for mainnet. Copy the connection string.
-2. **Provision Redis.** Create a managed Redis instance for mainnet.
-3. **Provision an RPC provider.** Sign up / self-host a mainnet Soroban RPC
-   endpoint.
-4. **Deploy on Render.** Create a web service from the Lens repo/image and set
-   the mainnet env vars (below) in the Render dashboard — never in a committed
-   file.
-5. **Set up UptimeRobot.** Add a monitor for `https://<your-app>.onrender.com/status`
-   every 5 minutes.
-6. **Verify.** `curl https://<your-app>.onrender.com/status` should return
-   `"ok": true` with your mainnet watched pairs and a recent `lastIndexedLedger`.

+# Mainnet Deployment Guide (Render + UptimeRobot + Neon + external RPC)
+
+This runbook walks through running a **mainnet** Lens node on Render, kept
+awake by UptimeRobot, backed by a managed Postgres (Neon) and an external
+Soroban RPC provider.
+
+> **No secrets or keys are committed anywhere in this guide.** Every credential
+> below is a placeholder — set the real values in your Render dashboard / host
+> environment only.
+
+## Why mainnet is different from testnet
+
+Lens is already closer to mainnet than testnet out of the box: its Soroswap
+factory and Aquarius defaults are **mainnet** addresses. The Reflector oracle
+has no built-in default — supply `REFLECTOR_CONTRACT_ID_MAINNET` from
+[reflector.network](https://reflector.network) to enable it. To point a node at
+mainnet you mostly need to flip the network passphrase, Horizon/RPC URLs and
+set mainnet `WATCHED_PAIRS`.
+
+Two things have no free mainnet equivalent:
+
+- **Soroban RPC** — there is no free public mainnet Soroban RPC. You must bring
+  your own provider (see [RPC provider](#rpc-provider)).
+- **Render free Postgres** — it is **deleted after 90 days**. Use Neon or
+  another managed Postgres for any durable deployment.
+
+## Architecture
+
+```
+UptimeRobot ──GET /status──▶ Render web service (Lens)
+                                  │
+                                  ├── external Soroban RPC provider (RPC_URL)
+                                  ├── Horizon (https://horizon.stellar.org)
+                                  └── Neon Postgres (DATABASE_URL)
+                                  └── Redis (REDIS_URL)
+```
+
+- **Compute:** Render web service (free tier OK for a single node).
+- **Keep-alive:** UptimeRobot pings `/status` every 5 minutes so the free web
+  service never sleeps.
+- **Database:** Neon (or any managed Postgres) — **never** Render free Postgres.
+- **Cache/queues:** Redis (managed, e.g. Render Redis or Upstash).
+
+## Env matrix
+
+| Var | testnet | mainnet |
+|-----|---------|---------|
+| `STELLAR_NETWORK` | `testnet` | `mainnet` |
+| `HORIZON_URL` | `https://horizon-testnet.stellar.org` | `https://horizon.stellar.org` |
+| `RPC_URL` | `https://soroban-testnet.stellar.org` | external provider — **placeholder only** (see below) |
+| `NETWORK_PASSPHRASE` | `Test SDF Network ; September 2015` | `Public Global Stellar Network ; September 2015` |
+| `SOROSWAP_FACTORY_ADDRESS` | `CDP3HMUH6SMS3S7NPGNDJLULCOXXEPSHY4JKUKMBNQMATHDHWXRRJTBY` | `CA4HEQTL2WPEUYKYKCDOHCDNIV4QHNJ7EL4J4NQ6VADP7SYHVRYZ7AW2` |
+| `REFLECTOR_CONTRACT_ID` | *(empty)* | *(required to enable the oracle — copy from reflector.network)* |
+| `WATCHED_PAIRS` | testnet USDC issuer | mainnet USDC issuer |
+| `DATABASE_URL` | testnet DB | **separate** mainnet DB |
+| `REDIS_URL` | testnet Redis | **separate** mainnet Redis |
+
+> Lens resolves each field in this priority order: paired var
+> (`HORIZON_URL_MAINNET`) → generic var (`HORIZON_URL`) → built-in default.
+> Prefer the paired `_MAINNET` / `_TESTNET` vars so both networks can coexist
+> in one env file.
+
+### Mainnet USDC issuer
+
+The mainnet `WATCHED_PAIRS` uses the mainnet USDC issuer:
+
+```
+WATCHED_PAIRS_MAINNET=XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN
+```
+
+## RPC provider
+
+Mainnet has **no free Soroban RPC**. You must provision one from a provider
+(e.g. a hosted Soroban RPC service, a self-hosted `soroban-rpc` node, or a
+third-party RPC gateway). Set the endpoint in the host environment only:
+
+```
+RPC_URL_MAINNET=https://your-provider.example.com/soroban-rpc   # placeholder
+```
+
+Never commit a real provider URL or API key to the repo.
+
+## Render keep-alive (UptimeRobot)
+
+Render **free web services sleep** after ~15 minutes of inactivity. Because
+Lens is an indexer that must keep ingesting, you need a keep-alive:
+
+1. Deploy the Lens image as a Render **web service**.
+2. Create an UptimeRobot monitor that hits `GET /status` every **5 minutes**.
+   `/status` is public (no API key required) and returns indexer health.
+3. Each ping wakes the service and keeps it running.
+
+> **750 instance-hours/month free cap.** A single always-on free instance uses
+> 24 × 31 ≈ 744 hours/month — right at the cap. If you also run a testnet node,
+> either run it on-demand, on a second account, or upgrade to a paid instance.
+> See [Running testnet + mainnet side-by-side](#running-testnet--mainnet-side-by-side).
+
+## Database durability (Neon / managed Postgres)
+
+**Do not use Render's free Postgres for mainnet** — it is **deleted after
+90 days**. Use Neon or another managed Postgres with:
+
+- Automatic backups / point-in-time recovery.
+- A dedicated database per network.
+
+Lens is an aggregator, so the DB is also re-derivable by re-ingesting from
+chain — but a nightly `pg_dump` makes restores fast. See the
+[backup & restore runbook](../../issues/119) (L053) for the nightly `pg_dump`
+workflow and restore procedure.
+
+## Running testnet + mainnet side-by-side
+
+Run **two separate deployments** (same image, one env set each). Give each
+network its **own** database and Redis: every row now carries a `network`
+discriminator (#114), but separate stores keep the two deployments — and any
+read path not yet network-scoped — from pooling networks.
+
+| | testnet node | mainnet node |
+|---|---|---|
+| `STELLAR_NETWORK` | `testnet` | `mainnet` |
+| `DATABASE_URL` | `postgresql://…testnet…` | `postgresql://…mainnet…` |
+| `REDIS_URL` | `redis://…testnet…` | `redis://…mainnet…` |
+
+See [`docs/DUAL_NETWORK.md`](./DUAL_NETWORK.md) for the full dual-network
+architecture.
+
+## Step-by-step
+
+1. **Provision the database.** Create a Neon project (or your managed Postgres)
+   and a dedicated database for mainnet. Copy the connection string.
+2. **Provision Redis.** Create a managed Redis instance for mainnet.

-# Dual-Network (mainnet + testnet) — Foundation

-Goal: run Lens on **mainnet and testnet at the same time**, keeping testnet as

-
-## Architecture options
-

-2. **In-process dual-network.** One process ingests both networks — requires the

-of colliding. Redis cache keys carry a per-network prefix too.
-
-> Resolved: each network now has its own fully-resolved config block

-# Operations runbook
-
-How Lens actually behaves today: what runs, what breaks when it is unavailable,
-how to tell, and what to do. **Every claim here is checkable against the code
-at this commit** — the defining file or symbol is named next to each one.
-Where the system does the wrong thing, this document says so; it does not
-describe an aspirational system.
-
----
-
-## 1. Processes
-
-### The one process that matters
-
-Lens runs as a **single Node process** (`npm start` → `node dist/index.js`,
-`CMD` in `Dockerfile`). Everything below runs inside it — there is no separate
-worker, ingester or scheduler process:
-
-| Component | What it does | Where |
-|---|---|---|
-| HTTP API | REST routes, `/graphql` + GraphiQL, webhooks, x402 facilitator, admin/usage routes | `buildApp()` in `src/app.ts`, routes under `src/api/` and `src/routes/` |
-| WebSocket server | `graphql-transport-ws` subscriptions on `/graphql`; local fan-out plus cross-instance fan-out over Redis pub/sub | `src/ws/fanout.ts`, `src/ws/` |
-| Venue ingesters | One infinite poll loop per (venue × enabled network) for **SDEX**, **Horizon AMM**, **Soroswap**, **Aquarius** | registry `src/ingest/venues/index.ts`, started in `main()` (`src/index.ts`) via `startVenueAdapter` (`src/ingest/venues/runner.ts`) |
-| Snapshot ingester | Appends one `price_snapshots` row per active pair at every minute boundary, per network | `src/ingesters/snapshot.ts` |
-| BullMQ workers | `aggregate-refresh` (one queue/worker per network), `snapshot-retention` (hourly), `price_points` partition maintenance (hourly) — **in the same process** | `src/jobs/aggregateRefresh.ts`, `src/jobs/snapshotRetention.ts`, `src/jobs/pricePointsPartitionJob.ts` |
-| Webhook dispatcher | Threshold alerts, delivered inline after each ingested price write | `src/webhookDispatcher.ts`, `src/alerts/delivery.ts` |
-| Schema migration | `prisma migrate deploy` runs **at every boot, before the API listens** — committed migrations only, never a diff of the live schema (#233). On a database that predates the migration history the baseline is recorded as applied first, without running it | `applyMigrations()` in `src/db/migrate.ts`, called from `main()` (`src/index.ts`) — doc: [`docs/database-migrations.md`](database-migrations.md) |
-| Middleware | Network selector, API-key auth, per-key/IP rate limits, the per-instance global request ceiling (`GLOBAL_RATE_LIMIT_MAX`, sheds with 503), x402 payment gate, cache policy, HTTP metrics | `src/app.ts` registration order |
-| Health probes | `GET /live` (liveness) and `GET /ready` (readiness: boot state + Postgres/Redis), plus `GET /snapshot`, a cached whole-network freshness object | `src/health.ts`, `src/routes/health.ts`, `src/routes/snapshot.ts` — doc: [`docs/health.md`](health.md) |
-| Metrics | Prometheus registry exposed on `GET /metrics` | `src/metrics.ts`, route in `src/app.ts` |
-
-**Startup order and failure behaviour** (all in `main()`, `src/index.ts`):
-
-1. `applyMigrations()` — `prisma migrate deploy`, preceded by a one-time
-   `migrate resolve --applied <baseline>` when the schema exists without a
-   `_prisma_migrations` table. Failure throws → `fatal startup error`, exit 1.
-2. `redis.connect()` — **soft**: on failure logs `redis unavailable, continuing without cache` and continues.
-3. `pgPool.connect()` — **hard**: rejection → `fatal startup error`, exit 1.
-4. Load persisted pairs (`loadPersistedPairs()`).
-5. `buildApp()` + `app.listen()` — failure (e.g. port in use) → exit 1.
-6. `fanOutManager.initialize()` — soft, warn `websocket fan-out init skipped`.
-7. Aggregate-refresh worker per enabled network — soft, warn
-   `aggregate refresh worker skipped (redis unavailable)`. **No fallback is installed for this one.**
-8. Snapshot retention: prune once, then schedule hourly — on Redis failure warn
-   `falling back to an in-process hourly prune` and install an in-process `setInterval`.
-9. Price-points partition maintenance: same pattern, same in-process hourly fallback.
-10. Ingesters started per network through `restartIngester`: a crash is logged
-    (`ingester crashed; restarting in 10s`) and restarted after 10 s, isolated
-    per `(venue, network)` — one dying ingester does not affect the others.
-11. `markBootComplete()` — **last**, and only once every ingester above is
-    running: until that line `GET /ready` answers 503, keeping a starting
-    instance out of the load balancer (`src/index.ts`, `src/health.ts`).
-
-### Supporting services (`docker-compose.yml`)
-
-| Service | Notes |
-|---|---|
-| `lens` | Port 3002; `healthcheck: curl -f http://localhost:3002/status`, every 10 s, `start_period: 20s` |
-| `postgres` | `postgres:15-alpine`, volume `pgdata`, healthcheck `pg_isready` |
-| `redis` | `redis:7-alpine`, `--appendonly yes` (AOF persistence), volume `redisdata` |
-
-### Optional processes (not started by the server)
-
-`examples/oracle-relay`, `examples/alert-bot`, `examples/mcp-server` (stdio),
-and `scripts/*` (smoke, seed, key issuance) are run manually via their npm
-scripts. Nothing in `src/index.ts` depends on them.
-
-### GitHub Actions
-
-| Workflow | Trigger | What it does |
-|---|---|---|
-| `ci.yml` | every PR and push to `main` | `npm ci` → `prisma generate` → `tsc --noEmit` → `npm run build` → `npm test` |
-| `release.yml` | push to `main` | changesets: version PR or tag (tag-only release, no npm publish) |
-| `openapi-publish.yml` | push to `main` | regenerates `openapi.json`, publishes to `gh-pages` |
-| `db-backup.yml` | daily 03:00 UTC | `pg_dump` per network, age-encrypted, 14-day artifact (see §5) |
-| `load.yml` | daily 04:00 UTC | k6 load test, p95 < 80 ms @ 5k RPS — **currently red on `main`, see §6** |

-("Redis is a cache and a job broker, not a source of truth" — comment in `src/index.ts`).
-
-| | Behaviour |
-|---|---|
-| Down at **boot** | `pgPool.connect()` rejects → `fatal startup error` → **process exits 1**. Nothing serves. |
-| Down at **runtime** | Queries throw → affected routes return 5xx. `/status` itself queries the DB, so it fails too. |
-| Where you see it | `GET /status` refused/500 **and `GET /ready` → 503 with `checks.postgres.status: "down"`** (the probe also asserts the schema exists via `to_regclass('public.indexer_state')`, so a reachable-but-unmigrated database reports not-ready too); `GET /metrics` → `http_requests_total{status_class="5xx"}` rising, `db_query_duration_seconds` tail; pino error logs. |
-| Recovery | Restore the nightly dump (`docs/backup-restore.md`, produced by `db-backup.yml`), or re-ingest from chain — Lens data is re-derivable by ingesting again (`docs/DEPLOY_MAINNET.md`). |
-
-### Redis — `REDIS_URL`
-
-**Used for:** the price cache (`getCachedPrice`/`setCachedPrice`, TTL
-`PRICE_CACHE_TTL`, default 10 s), BullMQ queues/workers, cross-instance
-WebSocket pub/sub.
-
-| | Behaviour |
-|---|---|
-| Down at **boot** | Soft: `redis unavailable, continuing without cache`. The API still serves — **every cache read falls back to Postgres** (`getCachedPrice` catches and returns `null`), writes are best-effort (swallowed). Per-worker effects: **aggregate refresh is skipped with no fallback**; retention and partition maintenance fall back to hourly in-process timers; ws cross-instance fan-out is skipped. |
-| Down at **runtime** | The client rejects commands immediately (`enableOfflineQueue: false`, `src/redis.ts` — no request hangs waiting for a connection), reconnects with backoff capped at 60 s, and logs at most **one `redis connection error` per minute**. Reads keep falling back to Postgres. BullMQ's own connections (separate ioredis instances) log `[ioredis] Unhandled error event` while away and pause the queue-driven jobs. |
-| What breaks concretely | • No cache: every `/price` request recomputes from Postgres — correct, just slower.<br>• **`price_aggregates` freeze** if the aggregate-refresh worker is not running (skipped at boot, or paused while BullMQ cannot reach Redis). Consumers: `/price/:assetA/:assetB/history`, `/screener`, and the GraphQL aggregate queries — their buckets stop advancing while `/price/:assetA/:assetB` keeps serving live values (it computes VWAP from `price_points` on a cache miss — `getAggregatedPrice`, `src/aggregator/vwap.ts`).<br>• Multi-instance WebSocket fan-out stops: clients still receive events published by *their own* instance (the local `priceEmitter` subscription always works — `src/ws/fanout.ts`), but not events from other instances.<br>• **Readiness fails**: `GET /ready` PINGs Redis and reports `down` (503) while Redis is away — the instance leaves rotation even though reads still work from Postgres (`READINESS_REDIS_CHECK=false` excludes Redis from readiness). |
-| Where you see it | `X-Cache: MISS` on every `/price` response (`src/api/rest.ts`); `/screener` and `/price/.../history` stop moving; `aggregate refresh worker skipped (redis unavailable)` / `redis connection error` in logs; `GET /ready` → 503 with `checks.redis.status: "down"`; `ws_messages_sent_total` low on one instance while ingestion metrics are healthy. **`GET /metrics` has no Redis gauge** — the cache signal is the `X-Cache` response header, the readiness signal is `/ready`. |
-| Note on #345 | The issue title says Redis is "noticed once and never again"; today's code reconnects forever with capped backoff and throttled logging (`src/redis.ts`). The genuinely unfixed part is the **missing aggregate-refresh fallback** (see §4). |
-
-### Stellar Horizon — `HORIZON_URL` / `HORIZON_URL_<NETWORK>`
-
-**Used for:** SDEX trade ingestion and Horizon AMM snapshots.
-
-| | Behaviour |
-|---|---|
-| Down / rate-limited | No 429-specific handling anywhere in the ingest path (#348). SDEX fetch failures are caught inside `fetchSdexTrades` (`src/ingest/venues/sdex.ts`), logged as `error fetching trades`, and the cycle continues having ingested nothing. Failures that escape an adapter fail the cycle and trigger exponential backoff 10 s → 60 s cap: `venue adapter cycle failed; retrying` (`src/ingest/venues/runner.ts`). |
-| Where you see it | `GET /status` → `ingestLagSeconds` grows; `GET /metrics` → `trades_ingested_total` flat, `time() - last_trade_timestamp` growing (staleness alert recipe: `docs/ingest-metrics.md`). |
-| Recovery | Automatic: backoff retries forever; ingestion resumes from the persisted cursor in `indexer_state` (`setIndexerCursor`), so no trades are skipped once Horizon recovers — only the outage window is missing. |
-
-### Soroban RPC, Soroswap factory, Aquarius API — `RPC_URL*`, `SOROSWAP_FACTORY_ADDRESS*`, `AQUARIUS_*`
-
-**Used for:** AMM pool reserves/snapshots (Soroswap), Aquarius pool discovery,
-Reflector oracle reads (on demand, not a background loop).
-
-| | Behaviour |
-|---|---|
-| Bad/missing config | `config.ts` warns naming the env var and disables the feature; the adapter logs `venue adapter is disabled — ingester not started` and returns. |
-| Down at runtime | Cycle failures back off like above. Aquarius is quieter: `if (!res.ok) return []` (`src/ingest/venues/aquarius.ts`) — **a failing API returns empty results with no error**. |
-| Where you see it | `GET /metrics` → `amm_snapshots_total` flat; `/pools` pool `timestamp` goes stale; the `ammPrice` half of `/price/:assetA/:assetB` stops updating while `sdexPrice` keeps moving. |
-
-### x402 facilitator — `X402_FACILITATOR_URL` (default `https://x402.org/facilitator`)
-
-**Used for:** verifying payments on the gated routes (`/price`, `/pools`,
-`/candles` — `GATED_ROUTES` in `src/middleware/x402.ts`). Only active when
-`ORACLE_PAYMENT_ADDRESS` is set; otherwise the plugin logs
-`[oracle] ORACLE_PAYMENT_ADDRESS not set — x402 gating disabled` and the gated
-routes are **free**.
-
-| | Behaviour |
-|---|---|
-| Unreachable / verify throws | Caught in the preHandler → **402** `{error: "Payment verification failed", reason: ...}` (fails closed). |
-| Settle fails | Settlement is async after the response is sent; failure is only logged `[oracle] x402 settle error` — the request was already served. |
-| Where you see it | Paying clients suddenly receive 402s; `GET /metrics` → `x402_payments_received_total` stops incrementing; `webhook`-style pino logs from the `oracle` logger. |
-
-### Subscriber webhook endpoints (outbound HTTP)
-
-**Used for:** threshold alerts registered via `POST /webhooks`.
-
-| | Behaviour |
-|---|---|
-| Failing subscriber | 10 s timeout, **3 attempts** with delays 1 s, 2 s (`retryDelayMs`, `src/alerts/delivery.ts`), **no jitter** (#341). A 4xx stops immediately; final failure is only logged `webhook delivery failed after retries`. Nothing is persisted or re-queued — **the event is gone** (#342). |
-| Where you see it | The `webhook` pino logger only. **`GET /metrics` exports no webhook series at all** — silence on `/metrics` does not mean delivery worked. |
-
-### Keep-alive monitor (production on Render free tier)
-
-`docs/DEPLOY_MAINNET.md`: Render free services sleep after ~15 min idle, so an
-UptimeRobot monitor pings `GET /status` every 5 minutes.
-
-| | Behaviour |
-|---|---|
-| Monitor stops / misconfigured | The service sleeps → `GET /status` connection refused **and ingestion sleeps with it** — staleness follows. |
-| Where you see it | `/status` refused while nothing else is wrong; UptimeRobot's own alerting. |
-
-### Environment variables
-
-There is **no central env validation** (#338): `WATCHED_PAIRS` format throws at
-startup (`parseWatchedPairs`, `src/config.ts` → fatal exit 1), everything else
-is read directly from `process.env` at first use. Common misconfigurations and
-their exact symptoms:
-
-| Misconfiguration | Symptom | Signal |
-|---|---|---|
-| Bad `DATABASE_URL` | Process never starts | log `fatal startup error`, exit 1 |
-| Bad `REDIS_URL` | Runs, uncached | boot warn `redis unavailable, continuing without cache`; `X-Cache: MISS` forever on `/price` |
-| `ORACLE_PAYMENT_ADDRESS` unset | Payment gating silently off — **gated data served free** | log `x402 gating disabled`; no 402s from `/price` |
-| `ADMIN_TOKEN` unset | Admin surface unusable (by design) | every `POST/DELETE /admin/keys` and `/admin/usage*` → **401** `code: admin_unauthorized` (`isAdminAuthorized`, `src/api/auth.ts`), counted in `admin_auth_failures_total` on `GET /metrics` |
-| `REQUIRE_API_KEY=false` | API-key auth off entirely | log `[auth] REQUIRE_API_KEY=false — API key authentication disabled` |
-| `GLOBAL_RATE_LIMIT_MAX` invalid (not a positive integer) | Process never starts | `buildApp` throws → `fatal startup error`, exit 1. Default ceiling when unset: 1000 req/min per instance, with expensive route templates shed at 80% and health probes exempt (`src/middleware/globalRateLimit.ts`) |
-| `READINESS_REDIS_CHECK=false` | Redis dropped from readiness | `GET /ready` no longer fails when Redis is down |
-| Bad `WATCHED_PAIRS` | Process never starts | log `fatal startup error` with the parse error, exit 1 |

-## 3. Telling whether ingestion is healthy
-
-### `GET /status` — liveness + lag, per network
-
-Public (no API key), rate-limit exempt — `/status`, `/live` and `/ready` are
-the `PROBE_PATHS` allow-list in `src/app.ts`, and all three are excluded from
-`http_requests_total` so probes neither throttle nor pollute the traffic
-metrics.
-Answers for one network: pass `?network=mainnet` or the `x-network` header.
-
-```json
-{
-  "ok": true,
-  "network": "testnet",
-  "watchedPairs": ["XLM:native/USDC:GBBD47..."],
-  "lastIndexedLedger": 53842917,
-  "lastProcessedAt": "2026-10-19T12:00:00.000Z",
-  "ingestLagSeconds": 4
-}
-```
-
-Read it honestly (implementation: `GET /status` handler, `src/api/rest.ts`):
-
-- **`ok: true` only means the DB query worked.** The handler returns `ok: true`
-  unconditionally — it does **not** assert freshness.
-- **`ingestLagSeconds`** = seconds since the most recent `indexer_state` write
-  for that network. It is `null` until the first write; `lastIndexedLedger` is
-  `null` until the SDEX ingester has recorded a ledger.
-- **Caveat, checkable in code:** only the **SDEX and AMM** ingesters write
-  `indexer_state` (`setIndexerCursor` in `src/ingest/venues/sdex.ts` and
-  `src/ingest/venues/amm.ts`), and only when a cycle actually ingested
-  records — a network with no trades in the window shows a growing lag **even
-  when everything is healthy**. Cross-check `/metrics` (below) before treating
-  lag alone as an incident. The 1-minute snapshot ingester is a separate loop
-  and never touches `indexer_state`.
-- The compose healthcheck (`docker-compose.yml`) and the Render keep-alive
-  monitor both poll this endpoint.
-
-### `GET /live` and `GET /ready` — the platform probes
-
-Both public, rate-limit exempt, and excluded from `http_requests_total`;
-rationale and semantics live in [`docs/health.md`](health.md).
-
-- **`GET /live`** — `200 {ok, uptimeSeconds}` as long as the event loop is
-  turning; it touches neither Postgres nor Redis. That is deliberate: a
-  liveness probe that fails during a dependency outage would have the
-  orchestrator restart every healthy instance at once.
-- **`GET /ready`** — `200` only after **boot completes** (`markBootComplete()`
-  is the last line of `main()`) **and** every checked dependency is up;
-  otherwise `503` carrying `booted`, `checks.postgres`, `checks.redis` and
-  `checkedAt`. Postgres is probed for reachability *and* migration state
-  (`to_regclass('public.indexer_state')`), Redis with `PING` (2 s probe
-  deadline, 2 s answer cache — `READINESS_TIMEOUT_MS` / `READINESS_CACHE_MS`;
-  `READINESS_REDIS_CHECK=false` drops Redis from readiness). Reasons in the
-  body are fixed phrases, never raw errors — the endpoint is public; the real
-  error is logged instead.
-
-### `GET /snapshot` — one-shot freshness view
-
-`GET /snapshot?network=…` returns the whole network's shape — venues, TVL, 24h
-volume, top pairs, peg readings and data freshness — in one cached, timestamped
-object (`src/routes/snapshot.ts`, cached in Redis via `getCachedSnapshot`).
-
-### `GET /metrics` — the freshness and error signals
-
-Public Prometheus exposition (`src/metrics.ts`, route in `src/app.ts`).
-
-**Ingestion health:**
-
-| Signal | Meaning / recipe |
-|---|---|
-| `rate(trades_ingested_total{network}[5m])` | Flat = SDEX/AMM ingestion stopped for those pairs |
-| `time() - last_trade_timestamp{pair,network}` | Per-pair staleness — the canonical alert; worked example in `docs/ingest-metrics.md` (labels are `pair × network`, bounded by config) |
-| `rate(amm_snapshots_total{network}[5m])` | AMM venue snapshots; flat = Soroswap/Aquarius/Horizon-AMM side stalled |
-| `rate(price_snapshots_total{network}[5m])` | Snapshot ingester; healthy ≈ (active pairs) rows/min per network |
-| `ws_clients_total`, `ws_messages_sent_total`, `ws_messages_dropped_total`, `ws_clients_dropped_total`, `ws_buffered_bytes` | Subscriber count, delivery rate, backpressure drops, clients killed and in-memory buffer depth (labels are bounded: `pair` is the literal key, `other`, or aggregate — see `docs/websocket-backpressure.md`) |
-
-**API health:**
-
-| Signal | Meaning |
-|---|---|
-| `http_requests_total{method,route,status_class}` | Rate and 5xx ratio; `route` is the route *template*, `status_class` is `2xx/4xx/5xx` — both deliberately bounded |
-| `http_request_duration_seconds` | Latency histogram with Lens-specific buckets (5 ms … 10 s); p95 recipe in `README.md` and `docs/http-metrics.md` |
-| `db_query_duration_seconds` | Postgres query latency (includes pool wait — the timer wraps `pgPool.query`) |
-| `api_key_auth_failures_total{reason}`, `admin_auth_failures_total` | Auth failures by bounded reason (`missing`/`malformed`/`unknown`/`revoked`/`expired`; admin counted separately) |
-| `rate_limit_rejections_total{scope}`, `global_shed_requests_total` | Per-key/IP limiter 429s (`key`/`ip`) and per-instance ceiling sheds (503) |
-| `x402_payments_received_total`, `price_requests_total` | Payment/request counters |
-
-**Known blind spots:** no gauge for Redis state, no gauge for the pg pool
-(see #339 in §4), no queue-lag metric, no webhook-delivery metric.
-
-### Triage sequence
-
-1. **Is the process answering?** `curl -s localhost:3002/live`, then `/ready`:
-   - *`/live` connection refused / sleeping* → process dead or host asleep (see §5 deploys, §2 keep-alive).
-   - *`/live` 200 but `/ready` 503* → boot not finished, or a checked dependency is down — the `checks` body says which (Postgres down/unmigrated, Redis down; §2).
-   - *`/status` 500 / refused* → PostgreSQL (§2).
-2. **Is data fresh?** `ingestLagSeconds` + `time() - last_trade_timestamp` (§3 caveat above).
-3. **Which layer?** grep the pino logs for the exact lines named in this
-   document: `fatal startup error`, `error fetching trades`,
-   `venue adapter cycle failed; retrying`, `ingester crashed; restarting in 10s`,
-   `redis connection error`, `aggregate refresh worker skipped`,
-   `webhook delivery failed after retries`, `[oracle] x402 settle error`.
-4. **Is it only the aggregates/cache?** `/price/:assetA/:assetB` fresh but `/screener` or
-   `/price/.../history` frozen → aggregate-refresh worker / Redis (§2).
-5. **Full deployed check:** `SMOKE_MAX_AGE_SECONDS=120 npm run smoke -- https://<host>`
-   (`scripts/deployed-smoke.mjs`) — asserts `/ready` + `/live` (it fails hard if
-   `/ready` 404s or reports `ok: false`), then `/status`, `/price`, and a live
-   `graphql-transport-ws` subscription. On an x402-gated installation an
-   unauthenticated `/price` call returns 402 and the smoke check **fails by
-   design**; it never bypasses payment (README).

-## 4. Known failure modes in this batch
-
-Each row states what the code does **today**, not what it should do, and names
-the endpoint, metric, or log line that shows it. Issue numbers are the open
-tracking issues for the batch this runbook was filed in.
-
-| # | Failure mode | What happens today (code) | Where you see it |
-|---|---|---|---|
-| 1 | **Unhandled rejection kills the process** (#344) | There is **no** `unhandledRejection`/`uncaughtException` handler anywhere in `src/`; Node's default is to exit — with no application log line for the cause. | Process gone: `GET /status` connection refused, compose healthcheck fails, `http_requests_total` flatlines while the container restarts. The cause is only inferable from the last log line before the exit. |
-| 2 | **Shutdown is not graceful** (#347) | There is **no** `SIGTERM`/`SIGINT` handler anywhere in `src/`; the process exits immediately. In-flight requests are cut and WebSocket clients are dropped **without a close frame**. | During any deploy/restart: WS clients see an abnormal closure (no `1000/1001` close frame), `ws_clients_total` disappears, `http_requests_total` stops mid-request. |
-| 3 | **Horizon rate limiting is not handled** (#348) | No 429 branch exists in the ingest path. SDEX 429s surface as a caught error → log `error fetching trades` → `null`, and the loop retries on the normal poll interval without backoff or accounting. | `GET /status` `ingestLagSeconds` grows; `GET /metrics` `trades_ingested_total` flat + stale `last_trade_timestamp`; repeating `error fetching trades` or `venue adapter cycle failed; retrying` in the logs. |
-| 4 | **A single ingester cycle has no deadline** (#351) | `startVenueAdapter` runs `while (true)` and awaits every watched pair **sequentially** with no cycle-level timeout (`src/ingest/venues/runner.ts`); there is no per-cycle upper bound. | The whole network's ingestion quietly spreads/stalls: `last_trade_timestamp` ages and `/status.ingestLagSeconds` grows **while no `venue adapter cycle failed` line appears** — no error, just lag. |
-| 5 | **Webhook retries have no jitter** (#341) | Delay is exactly `2^(attempt-1) × 1000` ms (`retryDelayMs`, `src/alerts/delivery.ts`) — subscribers triggered together retry together. | Bursts of `webhook delivery failed after retries` (logger `webhook`) arriving in lockstep after any upstream blip; `GET /metrics` has **no** webhook series to graph this. |
-| 6 | **A webhook that fails 3 times disappears** (#342) | After 3 attempts (or any 4xx on the first) the failure is logged and dropped — no persistence, no queue, no dead-letter. | The subscriber silently never receives the threshold event; the only trace is the `webhook` log line. Nothing on `/metrics` moves. |
-| 7 | **DB pool is default-sized and unmeasured** (#339) | `new Pool({connectionString})` with pg defaults (max 10 connections); instrumentation is only the `db_query_duration_seconds` histogram — no pool gauge exists (`src/db.ts`, `src/metrics.ts`). | Under saturation both `db_query_duration_seconds` and `http_request_duration_seconds` shift right together (the timer includes pool wait); `GET /metrics` offers **no waiter/pool gauge** to confirm it. |
-| 8 | **Env vars are not centrally validated** (#338) | Only `WATCHED_PAIRS` parsing throws at startup; every other variable is consumed lazily at first use. | Misconfiguration surfaces at first use — see the symptom table in §2 (bad `REDIS_URL` → `X-Cache: MISS` forever; unset `ORACLE_PAYMENT_ADDRESS` → gating silently off; unset `ADMIN_TOKEN` → admin routes always 401). |
-| 9 | **Redis away at boot: aggregate refresh has no fallback** (the unfixed half of #345) | Retention and partition maintenance fall back to hourly in-process timers when their BullMQ schedule fails at boot; the **aggregate-refresh worker does not** — it is skipped and never retried for the life of the process (`src/index.ts`). | `aggregate refresh worker skipped (redis unavailable)` at boot, then: `/screener` and `/price/:assetA/:assetB/history` (and GraphQL aggregate queries) freeze while `/price/:assetA/:assetB` keeps serving live prices from `price_points`. |

-## 5. Deploy, rollback, and what a deploy interrupts
-
-### How a deploy happens
-
-- **Production** (`docs/DEPLOY_MAINNET.md`): Render web service built from this
-  repo/image, env vars in the Render dashboard only, Neon Postgres, managed
-  Redis, UptimeRobot keep-alive on `/status`.
-- **Self-hosted / local**: `docker compose up -d --build` (image built by the
-  multi-stage `Dockerfile`, `CMD npm start`).
-- In both cases the boot sequence in §1 applies — **including the automatic
-  `prisma migrate deploy`**.
-
-### What a deploy interrupts
-
-1. **The schema changes to whatever the committed migrations say.** Step 1 of
-   boot runs `prisma migrate deploy` (`src/db/migrate.ts`) before the API
-   listens. Unlike the `db push` it replaced, it applies only migrations that
-   are in `prisma/migrations` and that a reviewer read — so a destructive change
-   reaches production because someone merged the SQL, not because a diff decided
-   it. It is still the one irreversible part of any deploy: read the pending
-   migrations before deploying, and take the backup path (rollback step 3) first
-   if any of them drops a column or a table.
-
-   The corollary of dropping `db push` is that drift is no longer self-healing.
-   A column present in `schema.prisma` but missing from the live database is
-   **not** added at boot any more — `migrate deploy` has nothing pending to
-   apply, and `assertSchemaValid()` only covers the five core tables in
-   `EXPECTED_SCHEMA`. Fix it with a committed migration; see the one-time check
-   in [`docs/database-migrations.md`](database-migrations.md).
-2. **The API is down until `listen` returns, and not *ready* until boot ends.**
-   Single instance ⇒ no rolling deploy; compose allows 20 s (`start_period`)
-   before healthchecks fail. `GET /ready` stays 503 from process start until
-   `markBootComplete()` — gate rollouts on `/ready`; `/live` alone only proves
-   the event loop turns.
-3. **No graceful shutdown** (#347, §4): in-flight requests are cut and WS
-   clients are dropped without a close frame.
-4. **Ingestion pauses for the restart, then resumes from persisted cursors.**
-   Cursor state lives in `indexer_state`, writes are idempotent
-   (`skipDuplicates` in `upsertPricePoints`, `ON CONFLICT DO NOTHING` on
-   snapshots), so replay after restart is safe; the gap is the trades that
-   happened while the process was down (visible as missing `price_points` for
-   that window and a lag spike in `/status`).
-5. **In-memory state is lost:** rate-limit windows (429 counters reset), WS
-   client list, the ingesters' last-price map (the webhook previous-price
-   baseline restarts, so the first post-restart tick compares against itself).
-   Redis, being external, keeps the price cache warm across a deploy.
-6. **Maintenance jobs re-run safely.** Prune and partition maintenance run once
-   at boot regardless, the hourly schedules are re-registered, and BullMQ jobs
-   are at-least-once — safe here because every job is an upsert/prune.
-
-### How to roll back
-
-1. **App code:** redeploy the previous known-good revision —
-   Render: roll back to the previous deploy in the dashboard;
-   self-hosted: `git checkout <good-sha> && docker compose up -d --build`.
-2. **Schema:** migrations are forward-only — Prisma generates no down-migration
-   — so rolling back the code does not roll back the schema. Roll *forward*:
-   commit a migration that reverses the change and deploy it
-   (`npm run db:deploy`). Do **not** reach for `prisma db push` from the old
-   checkout: it is gone from `package.json` for a reason, and a push against a
-   database that now has migration history leaves the two disagreeing. If the
-   previous revision cannot run against the new schema, the honest options are a
-   reversing migration or a restore from the dump — **take the backup path
-   (step 3) first** if either direction removes data.
-3. **Data (if a bad deploy or its auto-migration destroyed rows):** restore the
-   nightly dump per [`docs/backup-restore.md`](backup-restore.md) — dumps are
-   produced daily at 03:00 UTC by `.github/workflows/db-backup.yml`,
-   age-encrypted, 14-day retention. Alternatively re-ingest: Lens data is
-   re-derivable from chain (`docs/DEPLOY_MAINNET.md`), bounded only by how far
-   back the cursors point.
-4. **Config:** env vars live in the host (Render dashboard / `.env`), not in
-   the repo. Keep the previous env set alongside the previous image — a code
-   rollback with the new env is only half a rollback.
-5. **Verify the rollback:**
-   ```bash
-   curl -s https://<host>/ready                    # 200 {"ok":true,...}
-   curl -s https://<host>/status                  # ok:true, lag small
-   curl -s -o /dev/null -w '%{http_code}\n' https://<host>/price/XLM/USDC
-   # 200 (ungated) or 402 (x402-gated) — not 5xx
-   curl -s https://<host>/metrics | grep -E 'trades_ingested_total|last_trade_timestamp'
-   SMOKE_MAX_AGE_SECONDS=120 npm run smoke -- https://<host>
-   ```

-**`Load test (prices)` is failing on `main` and is a known, unrelated red.**
-It runs daily at 04:00 UTC (`load.yml`, k6 threshold p95 < 80 ms @ 5k RPS) and

+# Operations runbook
+
+How Lens actually behaves today: what runs, what breaks when it is unavailable,
+how to tell, and what to do. **Every claim here is checkable against the code
+at this commit** — the defining file or symbol is named next to each one.
+Where the system does the wrong thing, this document says so; it does not
+describe an aspirational system.
+
+---
+
+## 1. Processes
+
+### The one process that matters
+
+Lens runs as a **single Node process** (`npm start` → `node dist/index.js`,
+`CMD` in `Dockerfile`). Everything below runs inside it — there is no separate
+worker, ingester or scheduler process:
+
+| Component | What it does | Where |
+|---|---|---|
+| HTTP API | REST routes, `/graphql` + GraphiQL, webhooks, x402 facilitator, admin/usage routes | `buildApp()` in `src/app.ts`, routes under `src/api/` and `src/routes/` |
+| WebSocket server | `graphql-transport-ws` subscriptions on `/graphql`; local fan-out plus cross-instance fan-out over Redis pub/sub | `src/ws/fanout.ts`, `src/ws/` |
+| Venue ingesters | One infinite poll loop per (venue × enabled network) for **SDEX**, **Horizon AMM**, **Soroswap**, **Aquarius** | registry `src/ingest/venues/index.ts`, started in `main()` (`src/index.ts`) via `startVenueAdapter` (`src/ingest/venues/runner.ts`) |
+| Snapshot ingester | Appends one `price_snapshots` row per active pair at every minute boundary, per network | `src/ingesters/snapshot.ts` |
+| BullMQ workers | `aggregate-refresh` (one queue/worker per network), `snapshot-retention` (hourly), `price_points` partition maintenance (hourly) — **in the same process** | `src/jobs/aggregateRefresh.ts`, `src/jobs/snapshotRetention.ts`, `src/jobs/pricePointsPartitionJob.ts` |
+| Webhook dispatcher | Threshold alerts, delivered inline after each ingested price write | `src/webhookDispatcher.ts`, `src/alerts/delivery.ts` |
+| Schema migration | `prisma migrate deploy` runs **at every boot, before the API listens** — committed migrations only, never a diff of the live schema (#233). On a database that predates the migration history the baseline is recorded as applied first, without running it | `applyMigrations()` in `src/db/migrate.ts`, called from `main()` (`src/index.ts`) — doc: [`docs/database-migrations.md`](database-migrations.md) |
+| Middleware | Network selector, API-key auth, per-key/IP rate limits, the per-instance global request ceiling (`GLOBAL_RATE_LIMIT_MAX`, sheds with 503), x402 payment gate, cache policy, HTTP metrics | `src/app.ts` registration order |
+| Health probes | `GET /live` (liveness) and `GET /ready` (readiness: boot state + Postgres/Redis), plus `GET /snapshot`, a cached whole-network freshness object | `src/health.ts`, `src/routes/health.ts`, `src/routes/snapshot.ts` — doc: [`docs/health.md`](health.md) |
+| Metrics | Prometheus registry exposed on `GET /metrics` | `src/metrics.ts`, route in `src/app.ts` |
+
+**Startup order and failure behaviour** (all in `main()`, `src/index.ts`):
+
+1. `applyMigrations()` — `prisma migrate deploy`, preceded by a one-time
+   `migrate resolve --applied <baseline>` when the schema exists without a
+   `_prisma_migrations` table. Failure throws → `fatal startup error`, exit 1.
+2. `redis.connect()` — **soft**: on failure logs `redis unavailable, continuing without cache` and continues.
+3. `pgPool.connect()` — **hard**: rejection → `fatal startup error`, exit 1.
+4. Load persisted pairs (`loadPersistedPairs()`).
+5. `buildApp()` + `app.listen()` — failure (e.g. port in use) → exit 1.
+6. `fanOutManager.initialize()` — soft, warn `websocket fan-out init skipped`.
+7. Aggregate-refresh worker per enabled network — soft, warn
+   `aggregate refresh worker skipped (redis unavailable)`. **No fallback is installed for this one.**
+8. Snapshot retention: prune once, then schedule hourly — on Redis failure warn
+   `falling back to an in-process hourly prune` and install an in-process `setInterval`.
+9. Price-points partition maintenance: same pattern, same in-process hourly fallback.
+10. Ingesters started per network through `restartIngester`: a crash is logged
+    (`ingester crashed; restarting in 10s`) and restarted after 10 s, isolated
+    per `(venue, network)` — one dying ingester does not affect the others.
+11. `markBootComplete()` — **last**, and only once every ingester above is
+    running: until that line `GET /ready` answers 503, keeping a starting
+    instance out of the load balancer (`src/index.ts`, `src/health.ts`).
+
+### Supporting services (`docker-compose.yml`)
+
+| Service | Notes |
+|---|---|
+| `lens` | Port 3002; `healthcheck: curl -f http://localhost:3002/status`, every 10 s, `start_period: 20s` |
+| `postgres` | `postgres:15-alpine`, volume `pgdata`, healthcheck `pg_isready` |
+| `redis` | `redis:7-alpine`, `--appendonly yes` (AOF persistence), volume `redisdata` |
+
+### Optional processes (not started by the server)
+
+`examples/oracle-relay`, `examples/alert-bot`, `examples/mcp-server` (stdio),
+and `scripts/*` (smoke, seed, key issuance) are run manually via their npm
+scripts. Nothing in `src/index.ts` depends on them.
+
+### GitHub Actions
+
+| Workflow | Trigger | What it does |
+|---|---|---|
+| `ci.yml` | every PR and push to `main` | `npm ci` → `prisma generate` → `tsc --noEmit` → `npm run build` → `npm test` |
+| `release.yml` | push to `main` | changesets: version PR or tag (tag-only release, no npm publish) |
+| `openapi-publish.yml` | push to `main` | regenerates `openapi.json`, publishes to `gh-pages` |
+| `db-backup.yml` | daily 03:00 UTC | `pg_dump` per network, age-encrypted, 14-day artifact (see §5) |
+| `load.yml` | daily 04:00 UTC | k6 load test, p95 < 80 ms @ 5k RPS — **currently red on `main`, see §6** |
+

+
+## 2. External dependencies and what degrades without them
+
+### PostgreSQL — `DATABASE_URL`
+
+**Used for:** everything durable — `price_points`, `price_snapshots`,
+`pool_snapshots`, `price_aggregates`, `indexer_state`, pairs, webhooks,
+API keys/usage. It is the source of truth; Redis is only a cache
+("Redis is a cache and a job broker, not a source of truth" — comment in `src/index.ts`).
+
+| | Behaviour |
+|---|---|
+| Down at **boot** | `pgPool.connect()` rejects → `fatal startup error` → **process exits 1**. Nothing serves. |
+| Down at **runtime** | Queries throw → affected routes return 5xx. `/status` itself queries the DB, so it fails too. |
+| Where you see it | `GET /status` refused/500 **and `GET /ready` → 503 with `checks.postgres.status: "down"`** (the probe also asserts the schema exists via `to_regclass('public.indexer_state')`, so a reachable-but-unmigrated database reports not-ready too); `GET /metrics` → `http_requests_total{status_class="5xx"}` rising, `db_query_duration_seconds` tail; pino error logs. |
+| Recovery | Restore the nightly dump (`docs/backup-restore.md`, produced by `db-backup.yml`), or re-ingest from chain — Lens data is re-derivable by ingesting again (`docs/DEPLOY_MAINNET.md`). |
+
+### Redis — `REDIS_URL`
+
+**Used for:** the price cache (`getCachedPrice`/`setCachedPrice`, TTL
+`PRICE_CACHE_TTL`, default 10 s), BullMQ queues/workers, cross-instance
+WebSocket pub/sub.
+
+| | Behaviour |
+|---|---|
+| Down at **boot** | Soft: `redis unavailable, continuing without cache`. The API still serves — **every cache read falls back to Postgres** (`getCachedPrice` catches and returns `null`), writes are best-effort (swallowed). Per-worker effects: **aggregate refresh is skipped with no fallback**; retention and partition maintenance fall back to hourly in-process timers; ws cross-instance fan-out is skipped. |
+| Down at **runtime** | The client rejects commands immediately (`enableOfflineQueue: false`, `src/redis.ts` — no request hangs waiting for a connection), reconnects with backoff capped at 60 s, and logs at most **one `redis connection error` per minute**. Reads keep falling back to Postgres. BullMQ's own connections (separate ioredis instances) log `[ioredis] Unhandled error event` while away and pause the queue-driven jobs. |
+| What breaks concretely | • No cache: every `/price` request recomputes from Postgres — correct, just slower.<br>• **`price_aggregates` freeze** if the aggregate-refresh worker is not running (skipped at boot, or paused while BullMQ cannot reach Redis). Consumers: `/price/:assetA/:assetB/history`, `/screener`, and the GraphQL aggregate queries — their buckets stop advancing while `/price/:assetA/:assetB` keeps serving live values (it computes VWAP from `price_points` on a cache miss — `getAggregatedPrice`, `src/aggregator/vwap.ts`).<br>• Multi-instance WebSocket fan-out stops: clients still receive events published by *their own* instance (the local `priceEmitter` subscription always works — `src/ws/fanout.ts`), but not events from other instances.<br>• **Readiness fails**: `GET /ready` PINGs Redis and reports `down` (503) while Redis is away — the instance leaves rotation even though reads still work from Postgres (`READINESS_REDIS_CHECK=false` excludes Redis from readiness). |
+| Where you see it | `X-Cache: MISS` on every `/price` response (`src/api/rest.ts`); `/screener` and `/price/.../history` stop moving; `aggregate refresh worker skipped (redis unavailable)` / `redis connection error` in logs; `GET /ready` → 503 with `checks.redis.status: "down"`; `ws_messages_sent_total` low on one instance while ingestion metrics are healthy. **`GET /metrics` has no Redis gauge** — the cache signal is the `X-Cache` response header, the readiness signal is `/ready`. |
+| Note on #345 | The issue title says Redis is "noticed once and never again"; today's code reconnects forever with capped backoff and throttled logging (`src/redis.ts`). The genuinely unfixed part is the **missing aggregate-refresh fallback** (see §4). |
+
+### Stellar Horizon — `HORIZON_URL` / `HORIZON_URL_<NETWORK>`
+
+**Used for:** SDEX trade ingestion and Horizon AMM snapshots.
+
+| | Behaviour |
+|---|---|
+| Down / rate-limited | No 429-specific handling anywhere in the ingest path (#348). SDEX fetch failures are caught inside `fetchSdexTrades` (`src/ingest/venues/sdex.ts`), logged as `error fetching trades`, and the cycle continues having ingested nothing. Failures that escape an adapter fail the cycle and trigger exponential backoff 10 s → 60 s cap: `venue adapter cycle failed; retrying` (`src/ingest/venues/runner.ts`). |
+| Where you see it | `GET /status` → `ingestLagSeconds` grows; `GET /metrics` → `trades_ingested_total` flat, `time() - last_trade_timestamp` growing (staleness alert recipe: `docs/ingest-metrics.md`). |
+| Recovery | Automatic: backoff retries forever; ingestion resumes from the persisted cursor in `indexer_state` (`setIndexerCursor`), so no trades are skipped once Horizon recovers — only the outage window is missing. |
+
+### Soroban RPC, Soroswap factory, Aquarius API — `RPC_URL*`, `SOROSWAP_FACTORY_ADDRESS*`, `AQUARIUS_*`
+
+**Used for:** AMM pool reserves/snapshots (Soroswap), Aquarius pool discovery,
+Reflector oracle reads (on demand, not a background loop).
+
+| | Behaviour |
+|---|---|
+| Bad/missing config | `config.ts` warns naming the env var and disables the feature; the adapter logs `venue adapter is disabled — ingester not started` and returns. |
+| Down at runtime | Cycle failures back off like above. Aquarius is quieter: `if (!res.ok) return []` (`src/ingest/venues/aquarius.ts`) — **a failing API returns empty results with no error**. |
+| Where you see it | `GET /metrics` → `amm_snapshots_total` flat; `/pools` pool `timestamp` goes stale; the `ammPrice` half of `/price/:assetA/:assetB` stops updating while `sdexPrice` keeps moving. |
+
+### x402 facilitator — `X402_FACILITATOR_URL` (default `https://x402.org/facilitator`)
+
+**Used for:** verifying payments on the gated routes (`/price`, `/pools`,
+`/candles` — `GATED_ROUTES` in `src/middleware/x402.ts`). Only active when
+`ORACLE_PAYMENT_ADDRESS` is set; otherwise the plugin logs
+`[oracle] ORACLE_PAYMENT_ADDRESS not set — x402 gating disabled` and the gated
+routes are **free**.
+
+| | Behaviour |
+|---|---|
+| Unreachable / verify throws | Caught in the preHandler → **402** `{error: "Payment verification failed", reason: ...}` (fails closed). |
+| Settle fails | Settlement is async after the response is sent; failure is only logged `[oracle] x402 settle error` — the request was already served. |
+| Where you see it | Paying clients suddenly receive 402s; `GET /metrics` → `x402_payments_received_total` stops incrementing; `webhook`-style pino logs from the `oracle` logger. |
+
+### Subscriber webhook endpoints (outbound HTTP)
+
+**Used for:** threshold alerts registered via `POST /webhooks`.
+
+| | Behaviour |
+|---|---|
+| Failing subscriber | 10 s timeout, **3 attempts** with delays 1 s, 2 s (`retryDelayMs`, `src/alerts/delivery.ts`), **no jitter** (#341). A 4xx stops immediately; final failure is only logged `webhook delivery failed after retries`. Nothing is persisted or re-queued — **the event is gone** (#342). |
+| Where you see it | The `webhook` pino logger only. **`GET /metrics` exports no webhook series at all** — silence on `/metrics` does not mean delivery worked. |
+
+### Keep-alive monitor (production on Render free tier)
+
+`docs/DEPLOY_MAINNET.md`: Render free services sleep after ~15 min idle, so an
+UptimeRobot monitor pings `GET /status` every 5 minutes.
+
+| | Behaviour |
+|---|---|
+| Monitor stops / misconfigured | The service sleeps → `GET /status` connection refused **and ingestion sleeps with it** — staleness follows. |
+| Where you see it | `/status` refused while nothing else is wrong; UptimeRobot's own alerting. |
+
+### Environment variables
+
+There is **no central env validation** (#338): `WATCHED_PAIRS` format throws at
+startup (`parseWatchedPairs`, `src/config.ts` → fatal exit 1), everything else
+is read directly from `process.env` at first use. Common misconfigurations and
+their exact symptoms:
+
+| Misconfiguration | Symptom | Signal |
+|---|---|---|
+| Bad `DATABASE_URL` | Process never starts | log `fatal startup error`, exit 1 |
+| Bad `REDIS_URL` | Runs, uncached | boot warn `redis unavailable, continuing without cache`; `X-Cache: MISS` forever on `/price` |
+| `ORACLE_PAYMENT_ADDRESS` unset | Payment gating silently off — **gated data served free** | log `x402 gating disabled`; no 402s from `/price` |
+| `ADMIN_TOKEN` unset | Admin surface unusable (by design) | every `POST/DELETE /admin/keys` and `/admin/usage*` → **401** `code: admin_unauthorized` (`isAdminAuthorized`, `src/api/auth.ts`), counted in `admin_auth_failures_total` on `GET /metrics` |
+| `REQUIRE_API_KEY=false` | API-key auth off entirely | log `[auth] REQUIRE_API_KEY=false — API key authentication disabled` |
+| `GLOBAL_RATE_LIMIT_MAX` invalid (not a positive integer) | Process never starts | `buildApp` throws → `fatal startup error`, exit 1. Default ceiling when unset: 1000 req/min per instance, with expensive route templates shed at 80% and health probes exempt (`src/middleware/globalRateLimit.ts`) |
+| `READINESS_REDIS_CHECK=false` | Redis dropped from readiness | `GET /ready` no longer fails when Redis is down |
+| Bad `WATCHED_PAIRS` | Process never starts | log `fatal startup error` with the parse error, exit 1 |
+
+---
+
+## 3. Telling whether ingestion is healthy
+
+### `GET /status` — liveness + lag, per network
+
+Public (no API key), rate-limit exempt — `/status`, `/live` and `/ready` are
+the `PROBE_PATHS` allow-list in `src/app.ts`, and all three are excluded from
+`http_requests_total` so probes neither throttle nor pollute the traffic
+metrics.
+Answers for one network: pass `?network=mainnet` or the `x-network` header.
+
+```json
+{
+  "ok": true,
+  "network": "testnet",
+  "watchedPairs": ["XLM:native/USDC:GBBD47..."],
+  "lastIndexedLedger": 53842917,
+  "lastProcessedAt": "2026-10-19T12:00:00.000Z",
+  "ingestLagSeconds": 4
+}
+```
+
+Read it honestly (implementation: `GET /status` handler, `src/api/rest.ts`):
+
+- **`ok: true` only means the DB query worked.** The handler returns `ok: true`
+  unconditionally — it does **not** assert freshness.
+- **`ingestLagSeconds`** = seconds since the most recent `indexer_state` write
+  for that network. It is `null` until the first write; `lastIndexedLedger` is
+  `null` until the SDEX ingester has recorded a ledger.
+- **Caveat, checkable in code:** only the **SDEX and AMM** ingesters write
+  `indexer_state` (`setIndexerCursor` in `src/ingest/venues/sdex.ts` and
+  `src/ingest/venues/amm.ts`), and only when a cycle actually ingested
+  records — a network with no trades in the window shows a growing lag **even
+  when everything is healthy**. Cross-check `/metrics` (below) before treating
+  lag alone as an incident. The 1-minute snapshot ingester is a separate loop
+  and never touches `indexer_state`.
+- The compose healthcheck (`docker-compose.yml`) and the Render keep-alive
+  monitor both poll this endpoint.
+
+### `GET /live` and `GET /ready` — the platform probes
+
+Both public, rate-limit exempt, and excluded from `http_requests_total`;
+rationale and semantics live in [`docs/health.md`](health.md).
+
+- **`GET /live`** — `200 {ok, uptimeSeconds}` as long as the event loop is
+  turning; it touches neither Postgres nor Redis. That is deliberate: a
+  liveness probe that fails during a dependency outage would have the
+  orchestrator restart every healthy instance at once.
+- **`GET /ready`** — `200` only after **boot completes** (`markBootComplete()`
+  is the last line of `main()`) **and** every checked dependency is up;
+  otherwise `503` carrying `booted`, `checks.postgres`, `checks.redis` and
+  `checkedAt`. Postgres is probed for reachability *and* migration state
+  (`to_regclass('public.indexer_state')`), Redis with `PING` (2 s probe
+  deadline, 2 s answer cache — `READINESS_TIMEOUT_MS` / `READINESS_CACHE_MS`;
+  `READINESS_REDIS_CHECK=false` drops Redis from readiness). Reasons in the
+  body are fixed phrases, never raw errors — the endpoint is public; the real
+  error is logged instead.
+
+### `GET /snapshot` — one-shot freshness view
+
+`GET /snapshot?network=…` returns the whole network's shape — venues, TVL, 24h
+volume, top pairs, peg readings and data freshness — in one cached, timestamped
+object (`src/routes/snapshot.ts`, cached in Redis via `getCachedSnapshot`).
+
+### `GET /metrics` — the freshness and error signals
+
+Public Prometheus exposition (`src/metrics.ts`, route in `src/app.ts`).
+
+**Ingestion health:**
+
+| Signal | Meaning / recipe |
+|---|---|
+| `rate(trades_ingested_total{network}[5m])` | Flat = SDEX/AMM ingestion stopped for those pairs |
+| `time() - last_trade_timestamp{pair,network}` | Per-pair staleness — the canonical alert; worked example in `docs/ingest-metrics.md` (labels are `pair × network`, bounded by config) |
+| `rate(amm_snapshots_total{network}[5m])` | AMM venue snapshots; flat = Soroswap/Aquarius/Horizon-AMM side stalled |
+| `rate(price_snapshots_total{network}[5m])` | Snapshot ingester; healthy ≈ (active pairs) rows/min per network |
+| `ws_clients_total`, `ws_messages_sent_total`, `ws_messages_dropped_total`, `ws_clients_dropped_total`, `ws_buffered_bytes` | Subscriber count, delivery rate, backpressure drops, clients killed and in-memory buffer depth (labels are bounded: `pair` is the literal key, `other`, or aggregate — see `docs/websocket-backpressure.md`) |
+
+**API health:**
+
+| Signal | Meaning |
+|---|---|
+| `http_requests_total{method,route,status_class}` | Rate and 5xx ratio; `route` is the route *template*, `status_class` is `2xx/4xx/5xx` — both deliberately bounded |
+| `http_request_duration_seconds` | Latency histogram with Lens-specific buckets (5 ms … 10 s); p95 recipe in `README.md` and `docs/http-metrics.md` |
+| `db_query_duration_seconds` | Postgres query latency (includes pool wait — the timer wraps `pgPool.query`) |
+| `api_key_auth_failures_total{reason}`, `admin_auth_failures_total` | Auth failures by bounded reason (`missing`/`malformed`/`unknown`/`revoked`/`expired`; admin counted separately) |
+| `rate_limit_rejections_total{scope}`, `global_shed_requests_total` | Per-key/IP limiter 429s (`key`/`ip`) and per-instance ceiling sheds (503) |
+| `x402_payments_received_total`, `price_requests_total` | Payment/request counters |
+
+**Known blind spots:** no gauge for Redis state, no gauge for the pg pool
+(see #339 in §4), no queue-lag metric, no webhook-delivery metric.
+
+### Triage sequence
+
+1. **Is the process answering?** `curl -s localhost:3002/live`, then `/ready`:
+   - *`/live` connection refused / sleeping* → process dead or host asleep (see §5 deploys, §2 keep-alive).
+   - *`/live` 200 but `/ready` 503* → boot not finished, or a checked dependency is down — the `checks` body says which (Postgres down/unmigrated, Redis down; §2).
+   - *`/status` 500 / refused* → PostgreSQL (§2).
+2. **Is data fresh?** `ingestLagSeconds` + `time() - last_trade_timestamp` (§3 caveat above).
+3. **Which layer?** grep the pino logs for the exact lines named in this
+   document: `fatal startup error`, `error fetching trades`,
+   `venue adapter cycle failed; retrying`, `ingester crashed; restarting in 10s`,
+   `redis connection error`, `aggregate refresh worker skipped`,
+   `webhook delivery failed after retries`, `[oracle] x402 settle error`.
+4. **Is it only the aggregates/cache?** `/price/:assetA/:assetB` fresh but `/screener` or
+   `/price/.../history` frozen → aggregate-refresh worker / Redis (§2).
+5. **Full deployed check:** `SMOKE_MAX_AGE_SECONDS=120 npm run smoke -- https://<host>`
+   (`scripts/deployed-smoke.mjs`) — asserts `/ready` + `/live` (it fails hard if
+   `/ready` 404s or reports `ok: false`), then `/status`, `/price`, and a live
+   `graphql-transport-ws` subscription. On an x402-gated installation an
+   unauthenticated `/price` call returns 402 and the smoke check **fails by
+   design**; it never bypasses payment (README).

+
+## 4. Known failure modes in this batch
+
+Each row states what the code does **today**, not what it should do, and names
+the endpoint, metric, or log line that shows it. Issue numbers are the open
+tracking issues for the batch this runbook was filed in.
+
+| # | Failure mode | What happens today (code) | Where you see it |
+|---|---|---|---|
+| 1 | **Unhandled rejection kills the process** (#344) | There is **no** `unhandledRejection`/`uncaughtException` handler anywhere in `src/`; Node's default is to exit — with no application log line for the cause. | Process gone: `GET /status` connection refused, compose healthcheck fails, `http_requests_total` flatlines while the container restarts. The cause is only inferable from the last log line before the exit. |
+| 2 | **Shutdown is not graceful** (#347) | There is **no** `SIGTERM`/`SIGINT` handler anywhere in `src/`; the process exits immediately. In-flight requests are cut and WebSocket clients are dropped **without a close frame**. | During any deploy/restart: WS clients see an abnormal closure (no `1000/1001` close frame), `ws_clients_total` disappears, `http_requests_total` stops mid-request. |
+| 3 | **Horizon rate limiting is not handled** (#348) | No 429 branch exists in the ingest path. SDEX 429s surface as a caught error → log `error fetching trades` → `null`, and the loop retries on the normal poll interval without backoff or accounting. | `GET /status` `ingestLagSeconds` grows; `GET /metrics` `trades_ingested_total` flat + stale `last_trade_timestamp`; repeating `error fetching trades` or `venue adapter cycle failed; retrying` in the logs. |
+| 4 | **A single ingester cycle has no deadline** (#351) | `startVenueAdapter` runs `while (true)` and awaits every watched pair **sequentially** with no cycle-level timeout (`src/ingest/venues/runner.ts`); there is no per-cycle upper bound. | The whole network's ingestion quietly spreads/stalls: `last_trade_timestamp` ages and `/status.ingestLagSeconds` grows **while no `venue adapter cycle failed` line appears** — no error, just lag. |
+| 5 | **Webhook retries have no jitter** (#341) | Delay is exactly `2^(attempt-1) × 1000` ms (`retryDelayMs`, `src/alerts/delivery.ts`) — subscribers triggered together retry together. | Bursts of `webhook delivery failed after retries` (logger `webhook`) arriving in lockstep after any upstream blip; `GET /metrics` has **no** webhook series to graph this. |
+| 6 | **A webhook that fails 3 times disappears** (#342) | After 3 attempts (or any 4xx on the first) the failure is logged and dropped — no persistence, no queue, no dead-letter. | The subscriber silently never receives the threshold event; the only trace is the `webhook` log line. Nothing on `/metrics` moves. |
+| 7 | **DB pool is default-sized and unmeasured** (#339) | `new Pool({connectionString})` with pg defaults (max 10 connections); instrumentation is only the `db_query_duration_seconds` histogram — no pool gauge exists (`src/db.ts`, `src/metrics.ts`). | Under saturation both `db_query_duration_seconds` and `http_request_duration_seconds` shift right together (the timer includes pool wait); `GET /metrics` offers **no waiter/pool gauge** to confirm it. |
+| 8 | **Env vars are not centrally validated** (#338) | Only `WATCHED_PAIRS` parsing throws at startup; every other variable is consumed lazily at first use. | Misconfiguration surfaces at first use — see the symptom table in §2 (bad `REDIS_URL` → `X-Cache: MISS` forever; unset `ORACLE_PAYMENT_ADDRESS` → gating silently off; unset `ADMIN_TOKEN` → admin routes always 401). |
+| 9 | **Redis away at boot: aggregate refresh has no fallback** (the unfixed half of #345) | Retention and partition maintenance fall back to hourly in-process timers when their BullMQ schedule fails at boot; the **aggregate-refresh worker does not** — it is skipped and never retried for the life of the process (`src/index.ts`). | `aggregate refresh worker skipped (redis unavailable)` at boot, then: `/screener` and `/price/:assetA/:assetB/history` (and GraphQL aggregate queries) freeze while `/price/:assetA/:assetB` keeps serving live prices from `price_points`. |

+## 5. Deploy, rollback, and what a deploy interrupts
+
+### How a deploy happens
+
+- **Production** (`docs/DEPLOY_MAINNET.md`): Render web service built from this
+  repo/image, env vars in the Render dashboard only, Neon Postgres, managed
+  Redis, UptimeRobot keep-alive on `/status`.
+- **Self-hosted / local**: `docker compose up -d --build` (image built by the
+  multi-stage `Dockerfile`, `CMD npm start`).
+- In both cases the boot sequence in §1 applies — **including the automatic
+  `prisma migrate deploy`**.
+
+### What a deploy interrupts
+
+1. **The schema changes to whatever the committed migrations say.** Step 1 of
+   boot runs `prisma migrate deploy` (`src/db/migrate.ts`) before the API
+   listens. Unlike the `db push` it replaced, it applies only migrations that
+   are in `prisma/migrations` and that a reviewer read — so a destructive change
+   reaches production because someone merged the SQL, not because a diff decided
+   it. It is still the one irreversible part of any deploy: read the pending
+   migrations before deploying, and take the backup path (rollback step 3) first
+   if any of them drops a column or a table.
+
+   The corollary of dropping `db push` is that drift is no longer self-healing.
+   A column present in `schema.prisma` but missing from the live database is
+   **not** added at boot any more — `migrate deploy` has nothing pending to
+   apply, and `assertSchemaValid()` only covers the five core tables in
+   `EXPECTED_SCHEMA`. Fix it with a committed migration; see the one-time check
+   in [`docs/database-migrations.md`](database-migrations.md).
+2. **The API is down until `listen` returns, and not *ready* until boot ends.**
+   Single instance ⇒ no rolling deploy; compose allows 20 s (`start_period`)
+   before healthchecks fail. `GET /ready` stays 503 from process start until
+   `markBootComplete()` — gate rollouts on `/ready`; `/live` alone only proves
+   the event loop turns.
+3. **No graceful shutdown** (#347, §4): in-flight requests are cut and WS
+   clients are dropped without a close frame.
+4. **Ingestion pauses for the restart, then resumes from persisted cursors.**
+   Cursor state lives in `indexer_state`, writes are idempotent
+   (`skipDuplicates` in `upsertPricePoints`, `ON CONFLICT DO NOTHING` on
+   snapshots), so replay after restart is safe; the gap is the trades that
+   happened while the process was down (visible as missing `price_points` for
+   that window and a lag spike in `/status`).
+5. **In-memory state is lost:** rate-limit windows (429 counters reset), WS
+   client list, the ingesters' last-price map (the webhook previous-price
+   baseline restarts, so the first post-restart tick compares against itself).
+   Redis, being external, keeps the price cache warm across a deploy.
+6. **Maintenance jobs re-run safely.** Prune and partition maintenance run once
+   at boot regardless, the hourly schedules are re-registered, and BullMQ jobs
+   are at-least-once — safe here because every job is an upsert/prune.
+
+### How to roll back
+
+1. **App code:** redeploy the previous known-good revision —
+   Render: roll back to the previous deploy in the dashboard;
+   self-hosted: `git checkout <good-sha> && docker compose up -d --build`.
+2. **Schema:** migrations are forward-only — Prisma generates no down-migration
+   — so rolling back the code does not roll back the schema. Roll *forward*:
+   commit a migration that reverses the change and deploy it
+   (`npm run db:deploy`). Do **not** reach for `prisma db push` from the old
+   checkout: it is gone from `package.json` for a reason, and a push against a
+   database that now has migration history leaves the two disagreeing. If the
+   previous revision cannot run against the new schema, the honest options are a
+   reversing migration or a restore from the dump — **take the backup path
+   (step 3) first** if either direction removes data.
+3. **Data (if a bad deploy or its auto-migration destroyed rows):** restore the
+   nightly dump per [`docs/backup-restore.md`](backup-restore.md) — dumps are
+   produced daily at 03:00 UTC by `.github/workflows/db-backup.yml`,
+   age-encrypted, 14-day retention. Alternatively re-ingest: Lens data is
+   re-derivable from chain (`docs/DEPLOY_MAINNET.md`), bounded only by how far
+   back the cursors point.
+4. **Config:** env vars live in the host (Render dashboard / `.env`), not in
+   the repo. Keep the previous env set alongside the previous image — a code
+   rollback with the new env is only half a rollback.
+5. **Verify the rollback:**
+   ```bash
+   curl -s https://<host>/ready                    # 200 {"ok":true,...}
+   curl -s https://<host>/status                  # ok:true, lag small
+   curl -s -o /dev/null -w '%{http_code}\n' https://<host>/price/XLM/USDC
+   # 200 (ungated) or 402 (x402-gated) — not 5xx
+   curl -s https://<host>/metrics | grep -E 'trades_ingested_total|last_trade_timestamp'
+   SMOKE_MAX_AGE_SECONDS=120 npm run smoke -- https://<host>
+   ```
+
+---
+
+## 6. CI status on `main`
+
+The PR gate is `.github/workflows/ci.yml`; run it locally before opening a PR
+(identical to CONTRIBUTING's "Before opening a PR"):
+
+```bash
+npm ci
+node node_modules/prisma/build/index.js generate
+npx tsc --noEmit
+npm run build
+npm test --if-present
+```
+
+**`Load test (prices)` is failing on `main` and is a known, unrelated red.**
+It runs daily at 04:00 UTC (`load.yml`, k6 threshold p95 < 80 ms @ 5k RPS) and
+has been failing continuously — it is **not** your change that broke it. Every
+other check (CI build/typecheck/tests, release, OpenAPI publish, nightly
+backup) should be green; treat those as the gate.
+
+---

-## System Components
-
-### 1. Ingestion Layer
-Lens utilizes two distinct ingestion strategies to maintain up-to-date pricing data:
-
-*   **SDEX Ingester**: Streams trades directly from Stellar Horizon for watched asset pairs. It processes individual trade events in real-time, extracting price and volume data which is then persisted to the `price_points` table.
-*   **AMM Ingester**: Polls Horizon for liquidity pool snapshots and recent AMM trades. It stores pool reserves (Asset A/B amounts) in `pool_snapshots` and individual trades in `price_points`. This allows Lens to calculate spot prices based on reserve ratios even when no trades have occurred recently.
-
-### 2. Storage Layer
-Data is stored in a PostgreSQL database optimized with declarative range partitioning and time-series indexing.
-*   **`price_points`**: A unified table for all trade events across both SDEX and AMM, range-partitioned by `timestamp` into daily partitions (`price_points_yYYYYmMMdDD`). Automatic background workers pre-create future partitions ahead of need. Partition retention via metadata-only `DROP TABLE` operations is opt-in (`PRICE_POINTS_DROP_EXPIRED=true`, default: off) to safeguard raw historical records until rollups are completed (#231). Query execution plans on recent time windows leverage PostgreSQL partition pruning to scan only active partitions and skip all historical data.
-*   **`pool_snapshots`**: Stores the reserve state of AMM liquidity pools, which is critical for slippage estimation and constant-product price calculations.
-
-### 3. Aggregation & Routing (`bestRoute`)
-When a price is requested, the `bestRoute` engine compares the available liquidity on both SDEX and AMM:
-*   **SDEX Pricing**: Fetches real-time path payment quotes from Horizon to determine the effective rate for a specific trade size.
-*   **AMM Pricing**: Uses the constant-product formula (`x * y = k`) against the latest pool snapshots to estimate the output and slippage.
-*   **Optimal Routing**: Compares the rates and recommends the best execution path (SDEX, AMM, or a SPLIT for large orders) to minimize slippage for the user.
-
-### 4. API Layer & x402 Payment Gate
-The system exposes both REST and GraphQL interfaces. To monetize the high-fidelity data, Lens implements the **x402 protocol**.
-
-The **x402 Payment Gate** is a middleware that intercepts requests to premium endpoints (like `/price`, `/pools`, and `/candles`). If a valid `x-payment` header containing a signed Stellar transaction is not present, the server returns a `402 Payment Required` status along with the payment requirements (price, destination address, and network). This ensures that every high-value API call is backed by a micropayment, enabling a "pay-per-query" business model.

-# Backup and restore

-

-
-Neon also has branching and point-in-time restore. Use that for short-window
-accidents. The encrypted dump is the copy that survives a project delete or
-a missed PITR window.
-
-The workflow is [`.github/workflows/db-backup.yml`](../.github/workflows/db-backup.yml):
-cron `0 3 * * *` UTC plus `workflow_dispatch`. Encrypted artifacts are kept
-**14 days**.
-
-## Secrets
-
-Add these on the GitHub repo (Settings → Secrets and variables → Actions).
-Use the **direct** connection string, not the pooler:
-
-| Secret | What |
-|--------|------|
-| `DATABASE_URL_MAINNET` | mainnet Postgres (direct URI) |
-| `DATABASE_URL_TESTNET` | testnet Postgres (direct URI) |
-| `AGE_RECIPIENT` | `age` public key (`age1…`) |
-
-On Neon that means the host **without** `-pooler`, port **5432** (not 6543),
-and `sslmode=require`. Prisma's pooled `DATABASE_URL` is the runtime URL;
-`pg_dump` / `pg_restore` need the same class of URI as `DIRECT_DATABASE_URL`.
-
-Generate the keypair on a machine that is not the runner:
-
-```bash
-age-keygen -o lens-backup.agekey
-# public key line: age1…
-```
-
-Put only the public key in `AGE_RECIPIENT`. The identity file stays offline
-(password manager / disk not in this repo). GitHub never sees it.
-
-A missing database URL skips that network (`SKIP <network>: secret not
-configured`). A missing `AGE_RECIPIENT` fails the job — it will not upload
-plaintext.
-
-Do not put these URIs, the identity file, or a plaintext dump in the repo,
-`.env.example`, or workflow YAML.
-
-## Download a dump
-
-1. Actions → **Nightly DB backup** → the run you want.
-2. Artifacts: `lens-mainnet-<run_id>` / `lens-testnet-<run_id>`.
-3. File inside: `lens-<network>-YYYYMMDD.dump.gz.age`.
-
-`workflow_dispatch` is the way to take a dump on demand (and to verify the
-job once secrets are in place).
-
-## Restore into a fresh instance
-
-Do not `pg_restore` onto the live URL. Spin up an empty database, restore
-there, then swap the deployment env.
-
-1. Create a new Neon project (or local Postgres). Match the dump's major
-   version; if `pg_restore` complains, install a client ≥ the server
-   (`postgresql-client-16` / `17` as needed).
-2. Copy the **direct** URI for the new instance (`sslmode=require` on Neon).
-3. Decrypt with the offline identity, then restore **one network per
-   instance**:
-
-```bash
-age -d -i lens-backup.agekey \
-  -o lens-mainnet-YYYYMMDD.dump.gz \
-  lens-mainnet-YYYYMMDD.dump.gz.age
-
-gzip -dc lens-mainnet-YYYYMMDD.dump.gz \
-  | pg_restore --no-owner --no-acl --dbname="$NEW_DIRECT_URL"
-```
-
-`pg_restore -l` on the gunzipped file lists the TOC if you want to inspect
-before loading. Delete the decrypted `.dump.gz` when you are done.
-
-4. Point the matching Lens deployment at the new instance:
-   - `DATABASE_URL` — pooled URL is fine for the app
-   - `DIRECT_DATABASE_URL` — direct URL (Prisma `migrate deploy` / CLI)
-5. Check `/status`, then one `/prices/history` (or GraphQL equivalent) for a
-   watched pair.
-6. Rollback is swapping those two env vars back to the previous instance.
-
-Repeat independently for testnet with the testnet artifact and testnet
-deployment. Never restore a mainnet dump into testnet, or the reverse.
-
-## Client notes

-# Recipe: Price Alert Bot
-
-> Build a bot that notifies you the moment **XLM crosses a price you care
-> about** — e.g. *"tell me when XLM goes above $0.15"*.
-
-This recipe wires the Lens real-time WebSocket price stream into a tiny
-notifier. When the price crosses your threshold, the bot logs an alert and
-(optionally) POSTs a signed payload to any HTTPS endpoint — Slack, Discord,
-or your own service.
-
-A complete, runnable version of this recipe lives in
-[`examples/alert-bot`](../../examples/alert-bot). Everything below explains
-how it works so you can adapt it.
-
-## How it works
-
-```
-Lens indexer ──price:update──▶ /ws stream ──▶ alert bot ──crosses?──▶ notify
-```
-
-1. Lens ingests SDEX + AMM trades and emits a `price:update` whenever a
-   watched pair moves.
-2. The `/ws` endpoint fans those updates out to connected clients as
-   `price_update` messages, with backpressure-aware coalescing.
-3. The bot keeps the last price per pair and checks whether the move
-   **crossed** your threshold (not merely that it sits past it). Crossing
-   detection is the same `crossesThreshold` helper Lens uses internally, so
-   the bot and server agree on what "above" and "below" mean.
-4. On a crossing, the bot notifies you and — if `ALERT_BOT_NOTIFY_URL` is
-   set — delivers an HMAC-signed JSON payload with retries.
-
-> **Crossing vs. level:** the bot fires on the *transition* (`0.14 → 0.16`
-> crosses `0.15`), not on every tick above the line. That avoids alert
-> spam while the price hovers past your threshold.
-
-## The `price_update` message
-
-Each frame from `/ws` looks like:
-
-```json
-{
-  "type": "price_update",
-  "assetA": "XLM",
-  "assetB": "USDC",
-  "previousPrice": 0.1487,
-  "currentPrice": 0.1502,
-  "timestamp": "2026-06-28T18:46:02.114Z"
-}
-```
-
-The first frame on connect is a `{ "type": "status" }` message; if the
-stream is x402-gated and you didn't pay, you'll get
-`{ "type": "error", "status": 402, "requirements": { ... } }` instead (see
-[Paying for the stream](#paying-for-the-stream)).
-
-## Worked example
-
-The bot below is the heart of [`examples/alert-bot/alert-bot.ts`](../../examples/alert-bot/alert-bot.ts).
-
-```typescript
-import WebSocket from 'ws'
-import { crossesThreshold } from '../../src/alerts'
-
-const WS_URL = process.env.ALERT_BOT_WS_URL ?? 'ws://localhost:3002/ws'
-const config = {
-  assetA: 'XLM',
-  assetB: 'USDC',
-  threshold: 0.15,
-  direction: 'above' as const, // "above" | "below"
-}
-
-const pair = [config.assetA, config.assetB].sort().join('/')
-const ws = new WebSocket(WS_URL)
-
-ws.on('open', () => {
-  console.log(`watching ${config.assetA}/${config.assetB} ${config.direction} ${config.threshold}`)
-})
-
-ws.on('message', (data) => {
-  const msg = JSON.parse(data.toString())
-  if (msg.type !== 'price_update') return
-
-  // Match the pair regardless of asset order.
-  const got = [msg.assetA, msg.assetB].sort().join('/')
-  if (got !== pair) return
-
-  if (crossesThreshold(config, msg.previousPrice, msg.currentPrice)) {
-    console.log(`ALERT: ${pair} is ${config.direction} ${config.threshold} — now ${msg.currentPrice}`)
-    // → POST to Slack/Discord, send a push, page yourself, etc.
-  }
-})
-```
-
-### Run it
-
-```bash
-# 1. Start Lens (API + indexer)
-docker compose up -d
-
-# 2. Configure the alert and run the bot
-ALERT_BOT_THRESHOLD=0.15 ALERT_BOT_DIRECTION=above npm run alert:bot
-```
-
-Use `--once` to exit after the first alert (useful in tests/CI):
-
-```bash
-npm run alert:bot -- --once
-```
-
-Expected output once XLM ticks past `0.15`:
-
-```
-[alert-bot] connected to ws://localhost:3002/ws — watching XLM/USDC above 0.15
-[alert-bot] ALERT XLM/USDC is above 0.15 — price 0.1502 at 2026-06-28T18:46:02.114Z
-```
-
-## Sending the alert somewhere real
-
-Set `ALERT_BOT_NOTIFY_URL` to any HTTPS endpoint and the bot will POST the
-alert payload, signed with `X-Lens-Signature: hmac-sha256(secret, body)`:
-
-```bash
-ALERT_BOT_THRESHOLD=0.15 \
-ALERT_BOT_NOTIFY_URL=https://hooks.slack.com/services/your/webhook \
-ALERT_BOT_NOTIFY_SECRET=my-shared-secret \
-npm run alert:bot
-```
-
-The body matches the Lens threshold-alert shape:
-
-```json
-{
-  "assetA": "XLM",
-  "assetB": "USDC",
-  "price": 0.1502,
-  "threshold": 0.15,
-  "direction": "above",
-  "timestamp": "2026-06-28T18:46:02.114Z"
-}
-```
-
-Verify the signature on your side before trusting the payload:
-
-```typescript
-import { createHmac, timingSafeEqual } from 'crypto'
-
-function verify(rawBody: string, header: string, secret: string): boolean {
-  const expected = createHmac('sha256', secret).update(rawBody).digest('hex')
-  return timingSafeEqual(Buffer.from(expected), Buffer.from(header))
-}
-```
-
-## Paying for the stream
-
-If the server sets `ORACLE_PAYMENT_ADDRESS`, the `/ws` stream is x402-gated
-and the first frame will be a `402` with `requirements`. Sign a payment
-with `@x402/stellar`, base64-encode it, and pass it via `ALERT_BOT_PAYMENT`
-(sent as the `X-PAYMENT` header on connect). See the
-[README payment walkthrough](../../README.md#4-nodejs--automatic-payment-with-x402fetch--x402stellar)
-for how to produce that header. On testnet (the default), gating is off and
-no payment is needed.
-
-## Server-side alternative: webhooks
-
-If you'd rather not keep a process connected, Lens can do the watching for
-you. Register a webhook and Lens POSTs you (with the same HMAC signature)
-when the threshold is crossed:
-
-```bash
-curl -X POST http://localhost:3002/webhooks \
-  -H 'Content-Type: application/json' \
-  -d '{
-        "url": "https://example.com/hooks/xlm",
-        "assetA": "XLM",
-        "assetB": "USDC",
-        "threshold": 0.15,
-        "direction": "above"
-      }'
-# → { "id": "...", "secret": "..." }   (store the secret to verify signatures)
-```
-
-Delete it with `DELETE /webhooks/:id`. Use the **bot** when you want local
-control/custom logic, and **webhooks** when you want Lens to hold the
-subscription.
-
-If delivery permanently fails, Lens stores the endpoint host, alert
-payload, attempt count, final HTTP status (when available), failure category,
-and first/last attempt times. URL credentials, paths, query parameters,
-fragments, and the HMAC secret are excluded from the stored endpoint/record. Recent failures are
-available to operators at `GET /admin/webhook-delivery-failures` with an
-`X-Admin-Token` header; `limit` defaults to 25 and is capped at 100. Records are
-retained for 30 days. They are diagnostic only and are not replayed
-automatically, since a delayed threshold alert can be stale.

+# Recipe: Price Alert Bot
+
+> Build a bot that notifies you the moment **XLM crosses a price you care
+> about** — e.g. *"tell me when XLM goes above $0.15"*.
+
+This recipe wires the Lens real-time WebSocket price stream into a tiny
+notifier. When the price crosses your threshold, the bot logs an alert and
+(optionally) POSTs a signed payload to any HTTPS endpoint — Slack, Discord,
+or your own service.
+
+A complete, runnable version of this recipe lives in
+[`examples/alert-bot`](../../examples/alert-bot). Everything below explains
+how it works so you can adapt it.
+
+## How it works
+
+```
+Lens indexer ──price:update──▶ /ws stream ──▶ alert bot ──crosses?──▶ notify
+```
+
+1. Lens ingests SDEX + AMM trades and emits a `price:update` whenever a
+   watched pair moves.
+2. The `/ws` endpoint fans those updates out to connected clients as
+   `price_update` messages, with backpressure-aware coalescing.
+3. The bot keeps the last price per pair and checks whether the move
+   **crossed** your threshold (not merely that it sits past it). Crossing
+   detection is the same `crossesThreshold` helper Lens uses internally, so
+   the bot and server agree on what "above" and "below" mean.
+4. On a crossing, the bot notifies you and — if `ALERT_BOT_NOTIFY_URL` is
+   set — delivers an HMAC-signed JSON payload with retries.
+
+> **Crossing vs. level:** the bot fires on the *transition* (`0.14 → 0.16`
+> crosses `0.15`), not on every tick above the line. That avoids alert
+> spam while the price hovers past your threshold.
+
+## The `price_update` message
+
+Each frame from `/ws` looks like:
+
+```json
+{
+  "type": "price_update",
+  "assetA": "XLM",
+  "assetB": "USDC",
+  "previousPrice": 0.1487,
+  "currentPrice": 0.1502,
+  "timestamp": "2026-06-28T18:46:02.114Z"
+}
+```
+
+The first frame on connect is a `{ "type": "status" }` message; if the
+stream is x402-gated and you didn't pay, you'll get
+`{ "type": "error", "status": 402, "requirements": { ... } }` instead (see
+[Paying for the stream](#paying-for-the-stream)).
+
+## Worked example
+
+The bot below is the heart of [`examples/alert-bot/alert-bot.ts`](../../examples/alert-bot/alert-bot.ts).

+  direction: 'above' as const, // "above" | "below"
+}
+
+const pair = [config.assetA, config.assetB].sort().join('/')
+const ws = new WebSocket(WS_URL)
+
+ws.on('open', () => {
+  console.log(`watching ${config.assetA}/${config.assetB} ${config.direction} ${config.threshold}`)
+})
+
+ws.on('message', (data) => {
+  const msg = JSON.parse(data.toString())
+  if (msg.type !== 'price_update') return
+
+  // Match the pair regardless of asset order.
+  const got = [msg.assetA, msg.assetB].sort().join('/')
+  if (got !== pair) return
+
+  if (crossesThreshold(config, msg.previousPrice, msg.currentPrice)) {
+    console.log(`ALERT: ${pair} is ${config.direction} ${config.threshold} — now ${msg.currentPrice}`)
+    // → POST to Slack/Discord, send a push, page yourself, etc.

+docker compose up -d
+
+# 2. Configure the alert and run the bot
+ALERT_BOT_THRESHOLD=0.15 ALERT_BOT_DIRECTION=above npm run alert:bot
+```
+
+Use `--once` to exit after the first alert (useful in tests/CI):
+
+```bash
+npm run alert:bot -- --once
+```
+
+Expected output once XLM ticks past `0.15`:

-# Lens Data Quality Guarantees
-
-This document formally states the data quality guarantees provided by Lens: freshness, completeness, precision, venue inclusion, and the explicit system behaviors when any guarantee is violated. Every numerical bound documented below links directly to the code or configuration that enforces it.
-
----
-
-## Freshness Guarantees
-
-Lens continuously aggregates order book trades and AMM liquidity pool snapshots across Stellar networks. The following freshness bounds are enforced:
-
-### Live Pricing Staleness Bound
-A price response is considered fresh when its newest underlying trade observation occurred within [`300`](../src/aggregator/vwap.ts#L4) seconds ([`5`](../src/aggregator/vwap.ts#L4) minutes). When the newest observation age exceeds [`300`](../src/aggregator/vwap.ts#L4) seconds, the response explicitly sets `stale: true`.
-
-- **Enforcing Code**: [`src/aggregator/vwap.ts`](../src/aggregator/vwap.ts#L4) (`STALENESS_THRESHOLD_SECONDS`)
-- **Violation Behavior**: The engine returns the last observed price alongside `stale: true` and `lastTradeAgeSeconds: <age>` (exceeding [`300`](../src/aggregator/vwap.ts#L4) seconds). Confidence rating degrades to `'low'`.
-
-### Confidence Rating Freshness Tiers
-Every pricing response carries a categorical `confidence` rating derived from observation age and venue diversity:
-- **High Confidence**: Requires an observation age under [`30`](../src/aggregator/vwap.ts#L5) seconds across at least [`2`](../src/aggregator/vwap.ts#L187) distinct sources with positive [`24`](../src/aggregator/vwap.ts#L181)h volume.
-- **Medium Confidence**: Requires an observation age under [`300`](../src/aggregator/vwap.ts#L6) seconds.
-- **Low Confidence**: Assigned when observation age equals or exceeds [`300`](../src/aggregator/vwap.ts#L6) seconds.
-- **Unknown Confidence**: Assigned when no trades have ever been recorded (`lastTradeAgeSeconds === null`).
-- **Enforcing Code**: [`src/aggregator/vwap.ts`](../src/aggregator/vwap.ts#L4)
-
-### Venue Ingestion Liveness Window
-Venue adapters report network liveness on `/venues/registry`. A venue is marked `'live'` if a price point has been ingested within the last [`300000`](../src/routes/venues.ts#L7) ms ([`5`](../src/routes/venues.ts#L7) minutes).
-- **Enforcing Code**: [`src/routes/venues.ts`](../src/routes/venues.ts#L7) (`LIVE_WINDOW_MS`)
-- **Violation Behavior**: If no price points are observed within [`300000`](../src/routes/venues.ts#L7) ms, venue liveness transitions to `'stale'`. Disabled venues report `'disabled'`.
-
-### Ingestion Polling Intervals
-- **SDEX Order Book & AMM Trades**: Horizon ingestion polls every [`5000`](../src/config.ts#L266) ms with a batch page size of [`200`](../src/config.ts#L267) records for SDEX and [`200`](../src/config.ts#L268) records for AMM pools.
-- **Soroswap AMM Reserves**: Contract reserves poll via Soroban RPC every [`60000`](../src/config.ts#L178) ms.
-- **Enforcing Code**: [`src/config.ts`](../src/config.ts#L266) (`pollIntervalMs`, `soroswapPollMs`)
-
-### Cache Expiration & Network Timeouts
-- **Redis Price Cache TTL**: Aggregate prices are cached in Redis with a TTL of [`10`](../src/config.ts#L271) seconds.
-- **Outbound HTTP Timeout**: External HTTP requests enforce a deadline timeout of [`10000`](../src/config.ts#L274) ms.
-- **Enforcing Code**: [`src/config.ts`](../src/config.ts#L271) (`priceTtl`, `timeoutMs`)
-- **Violation Behavior**: Outbound calls abort upon reaching [`10000`](../src/config.ts#L274) ms; ingester logs errors and retries on subsequent poll ticks.
-
-### Snapshot and Partition Retention
-- **Pool Snapshot Pruning**: Historical liquidity pool snapshots older than [`30`](../src/jobs/snapshotRetention.ts#L12) days are pruned hourly in batches of [`1000`](../src/jobs/snapshotRetention.ts#L14) rows.
-- **Price Point Partition Dropping**: Daily `price_points` partitions older than [`30`](../src/partitioning/pricePoints.ts#L5) days are dropped.
-- **Enforcing Code**: [`src/jobs/snapshotRetention.ts`](../src/jobs/snapshotRetention.ts#L12), [`src/partitioning/pricePoints.ts`](../src/partitioning/pricePoints.ts#L5)
-
----
-
-## Completeness Guarantees
-
-### Multi-Venue Liquidity Aggregation
-High confidence requires price observations from at least [`2`](../src/aggregator/vwap.ts#L187) distinct liquidity sources (e.g. SDEX and AMM pools). When only [`1`](../src/aggregator/vwap.ts#L187) source is active, confidence is limited to `'medium'`.
-
-### Statistical Outlier Rejection Thresholds
-TWAP and VWAP computations apply statistical filtering to reject manipulation spikes:
-- **Minimum Sample Count**: Outlier filtering requires at least [`4`](../src/pricing/twap.ts#L288) sample points.
-- **Interquartile Range (IQR)**: Rejects samples beyond Q1 - [`1.5`](../src/pricing/twap.ts#L289) * IQR or Q3 + [`1.5`](../src/pricing/twap.ts#L289) * IQR.
-- **Modified Z-Score**: Rejects samples with absolute score exceeding [`3.5`](../src/pricing/twap.ts#L290), using a consistency factor of [`0.6745`](../src/pricing/twap.ts#L291).
-- **Enforcing Code**: [`src/pricing/twap.ts`](../src/pricing/twap.ts#L288)
-- **Violation Behavior**: If fewer than [`4`](../src/pricing/twap.ts#L288) samples exist, filtering is bypassed (`outlierRejected` is zero). If [`0`](../src/pricing/twap.ts#L78) samples exist in the window, endpoints return zero TWAP and sample count.
-
-### Request Window & Parameter Bounds
-- **TWAP Windows**: Window ranges from [`1`](../src/routes/price.ts#L8) to [`1440`](../src/routes/price.ts#L9) minutes (default [`60`](../src/routes/price.ts#L10) minutes). Sample intervals range from [`1`](../src/routes/price.ts#L11) to [`3600`](../src/routes/price.ts#L12) seconds (default [`60`](../src/routes/price.ts#L13) seconds).
-- **VWAP Windows**: Window ranges from [`1`](../src/routes/price.ts#L15) to [`1440`](../src/routes/price.ts#L16) minutes (default [`60`](../src/routes/price.ts#L17) minutes).
-- **Price History Limits**: Bucket count is capped at [`1000`](../src/api/rest.ts#L25) buckets (default [`100`](../src/api/rest.ts#L24) buckets).
-- **Screener Pair Limits**: Pair count defaults to [`20`](../src/routes/screener.ts#L22) and is clamped between [`1`](../src/routes/screener.ts#L33) and [`100`](../src/routes/screener.ts#L23).
-- **Spread Observations**: Venues must quote at least [`2`](../src/routes/spreads.ts#L20) observations in the window to report a spread.
-- **Violation Behavior**: Inputs outside allowed ranges trigger HTTP [`400`](../src/routes/price.ts#L55) Bad Request with validation details.
-
----
-
-## Precision Guarantees
-
-### Database Storage Precision
-- **Prices and VWAPs**: Stored as PostgreSQL `DECIMAL(`[`36`](../prisma/schema.prisma#L20)`, `[`18`](../prisma/schema.prisma#L20)`)` with [`18`](../prisma/schema.prisma#L20) decimal digits of fractional scale.
-- **Stellar Native Reserves & Volumes**: Stored as PostgreSQL `DECIMAL(`[`36`](../prisma/schema.prisma#L21)`, `[`7`](../prisma/schema.prisma#L21)`)` matching Stellar's native [`7`](../prisma/schema.prisma#L21) decimal place stroop scale ([`1`](../prisma/schema.prisma#L21) stroop = [`0.0000001`](../prisma/schema.prisma#L21) XLM).
-- **Enforcing Code**: [`prisma/schema.prisma`](../prisma/schema.prisma#L20)
-
-### API Boundary Serialization
-- **Standard Default Mode**: Returns numbers as IEEE-[`754`](../src/types.ts#L20) double precision floating-point numbers (~[`15`](../src/types.ts#L20)-[`17`](../src/types.ts#L20) significant digits).
-- **Exact String Representation Mode**: When negotiated via `X-Decimal-Format: string`, `Accept: application/json; decimals=strings`, or `?decimals=strings`, all decimal quantities serialise as exact strings without floating-point truncation.
-- **Enforcing Code**: [`prisma/schema.prisma`](../prisma/schema.prisma#L20), [`src/types.ts`](../src/types.ts#L20)
-- **Violation Behavior**: Consumers that require exact [`18`](../prisma/schema.prisma#L20)-decimal precision must negotiate string format; unnegotiated requests receive standard JSON numbers for backward compatibility.
-
----
-
-## Venue Inclusion Guarantees
-
-Lens integrates [`4`](../src/ingest/venues/index.ts#L19) registered venue adapters:
-
-| Venue | Identifier | Kind | Testnet | Mainnet | Included In | Enforcing Code |
-|---|---|---|---|---|---|---|
-| **Stellar Decentralized Exchange (SDEX)** | `sdex` | `orderbook` | Enabled | Enabled | VWAP, Best Route, Depth, Book, Volumes, Spreads | [`src/ingest/venues/sdex.ts`](../src/ingest/venues/sdex.ts#L174) |
-| **Stellar Native Liquidity Pools (AMM)** | `stellar-amm` | `amm` | Enabled | Enabled | Spot, Pools, Best Route, Depth, Book, Volumes | [`src/ingest/venues/amm.ts`](../src/ingest/venues/amm.ts#L237) |
-| **Soroswap AMM** | `soroswap` | `amm` | Enabled | Enabled | Price aggregation, multi-venue pools | [`src/ingest/venues/soroswap.ts`](../src/ingest/venues/soroswap.ts#L326) |
-| **Aquarius AMM** | `aquarius` | `amm` | Disabled | Enabled | Mainnet liquidity pool aggregation | [`src/ingest/venues/aquarius.ts`](../src/ingest/venues/aquarius.ts#L111) |
-
-- **Reflector Oracle**: Used optionally for oracle benchmark comparison (`/compare/:asset`) and GraphQL oracle resolution. Disabled by default unless configured.
-- **Enforcing Code**: [`src/ingest/venues/index.ts`](../src/ingest/venues/index.ts#L19), [`src/config.ts`](../src/config.ts#L171)
-

-## Violation Semantics Summary
-

+# Lens Data Quality Guarantees
+
+This document formally states the data quality guarantees provided by Lens: freshness, completeness, precision, venue inclusion, and the explicit system behaviors when any guarantee is violated. Every numerical bound documented below links directly to the code or configuration that enforces it.
+
+---
+
+## Freshness Guarantees
+
+Lens continuously aggregates order book trades and AMM liquidity pool snapshots across Stellar networks. The following freshness bounds are enforced:
+
+### Live Pricing Staleness Bound
+A price response is considered fresh when its newest underlying trade observation occurred within [`300`](../src/aggregator/vwap.ts#L4) seconds ([`5`](../src/aggregator/vwap.ts#L4) minutes). When the newest observation age exceeds [`300`](../src/aggregator/vwap.ts#L4) seconds, the response explicitly sets `stale: true`.
+
+- **Enforcing Code**: [`src/aggregator/vwap.ts`](../src/aggregator/vwap.ts#L4) (`STALENESS_THRESHOLD_SECONDS`)
+- **Violation Behavior**: The engine returns the last observed price alongside `stale: true` and `lastTradeAgeSeconds: <age>` (exceeding [`300`](../src/aggregator/vwap.ts#L4) seconds). Confidence rating degrades to `'low'`.
+
+### Confidence Rating Freshness Tiers
+Every pricing response carries a categorical `confidence` rating derived from observation age and venue diversity:
+- **High Confidence**: Requires an observation age under [`30`](../src/aggregator/vwap.ts#L5) seconds across at least [`2`](../src/aggregator/vwap.ts#L187) distinct sources with positive [`24`](../src/aggregator/vwap.ts#L181)h volume.
+- **Medium Confidence**: Requires an observation age under [`300`](../src/aggregator/vwap.ts#L6) seconds.
+- **Low Confidence**: Assigned when observation age equals or exceeds [`300`](../src/aggregator/vwap.ts#L6) seconds.
+- **Unknown Confidence**: Assigned when no trades have ever been recorded (`lastTradeAgeSeconds === null`).
+- **Enforcing Code**: [`src/aggregator/vwap.ts`](../src/aggregator/vwap.ts#L4)
+
+### Venue Ingestion Liveness Window
+Venue adapters report network liveness on `/venues/registry`. A venue is marked `'live'` if a price point has been ingested within the last [`300000`](../src/routes/venues.ts#L7) ms ([`5`](../src/routes/venues.ts#L7) minutes).
+- **Enforcing Code**: [`src/routes/venues.ts`](../src/routes/venues.ts#L7) (`LIVE_WINDOW_MS`)
+- **Violation Behavior**: If no price points are observed within [`300000`](../src/routes/venues.ts#L7) ms, venue liveness transitions to `'stale'`. Disabled venues report `'disabled'`.
+
+### Ingestion Polling Intervals
+- **SDEX Order Book & AMM Trades**: Horizon ingestion polls every [`5000`](../src/config.ts#L266) ms with a batch page size of [`200`](../src/config.ts#L267) records for SDEX and [`200`](../src/config.ts#L268) records for AMM pools.
+- **Soroswap AMM Reserves**: Contract reserves poll via Soroban RPC every [`60000`](../src/config.ts#L178) ms.
+- **Enforcing Code**: [`src/config.ts`](../src/config.ts#L266) (`pollIntervalMs`, `soroswapPollMs`)
+
+### Cache Expiration & Network Timeouts
+- **Redis Price Cache TTL**: Aggregate prices are cached in Redis with a TTL of [`10`](../src/config.ts#L271) seconds.
+- **Outbound HTTP Timeout**: External HTTP requests enforce a deadline timeout of [`10000`](../src/config.ts#L274) ms.
+- **Enforcing Code**: [`src/config.ts`](../src/config.ts#L271) (`priceTtl`, `timeoutMs`)
+- **Violation Behavior**: Outbound calls abort upon reaching [`10000`](../src/config.ts#L274) ms; ingester logs errors and retries on subsequent poll ticks.
+
+### Snapshot and Partition Retention
+- **Pool Snapshot Pruning**: Historical liquidity pool snapshots older than [`30`](../src/jobs/snapshotRetention.ts#L12) days are pruned hourly in batches of [`1000`](../src/jobs/snapshotRetention.ts#L14) rows.
+- **Price Point Partition Dropping**: Daily `price_points` partitions older than [`30`](../src/partitioning/pricePoints.ts#L5) days are dropped.
+- **Enforcing Code**: [`src/jobs/snapshotRetention.ts`](../src/jobs/snapshotRetention.ts#L12), [`src/partitioning/pricePoints.ts`](../src/partitioning/pricePoints.ts#L5)
+
+---
+
+## Completeness Guarantees
+
+### Multi-Venue Liquidity Aggregation
+High confidence requires price observations from at least [`2`](../src/aggregator/vwap.ts#L187) distinct liquidity sources (e.g. SDEX and AMM pools). When only [`1`](../src/aggregator/vwap.ts#L187) source is active, confidence is limited to `'medium'`.
+
+### Statistical Outlier Rejection Thresholds
+TWAP and VWAP computations apply statistical filtering to reject manipulation spikes:
+- **Minimum Sample Count**: Outlier filtering requires at least [`4`](../src/pricing/twap.ts#L288) sample points.
+- **Interquartile Range (IQR)**: Rejects samples beyond Q1 - [`1.5`](../src/pricing/twap.ts#L289) * IQR or Q3 + [`1.5`](../src/pricing/twap.ts#L289) * IQR.
+- **Modified Z-Score**: Rejects samples with absolute score exceeding [`3.5`](../src/pricing/twap.ts#L290), using a consistency factor of [`0.6745`](../src/pricing/twap.ts#L291).
+- **Enforcing Code**: [`src/pricing/twap.ts`](../src/pricing/twap.ts#L288)
+- **Violation Behavior**: If fewer than [`4`](../src/pricing/twap.ts#L288) samples exist, filtering is bypassed (`outlierRejected` is zero). If [`0`](../src/pricing/twap.ts#L78) samples exist in the window, endpoints return zero TWAP and sample count.
+
+### Request Window & Parameter Bounds
+- **TWAP Windows**: Window ranges from [`1`](../src/routes/price.ts#L8) to [`1440`](../src/routes/price.ts#L9) minutes (default [`60`](../src/routes/price.ts#L10) minutes). Sample intervals range from [`1`](../src/routes/price.ts#L11) to [`3600`](../src/routes/price.ts#L12) seconds (default [`60`](../src/routes/price.ts#L13) seconds).
+- **VWAP Windows**: Window ranges from [`1`](../src/routes/price.ts#L15) to [`1440`](../src/routes/price.ts#L16) minutes (default [`60`](../src/routes/price.ts#L17) minutes).
+- **Price History Limits**: Bucket count is capped at [`1000`](../src/api/rest.ts#L25) buckets (default [`100`](../src/api/rest.ts#L24) buckets).
+- **Screener Pair Limits**: Pair count defaults to [`20`](../src/routes/screener.ts#L22) and is clamped between [`1`](../src/routes/screener.ts#L33) and [`100`](../src/routes/screener.ts#L23).
+- **Spread Observations**: Venues must quote at least [`2`](../src/routes/spreads.ts#L20) observations in the window to report a spread.
+- **Violation Behavior**: Inputs outside allowed ranges trigger HTTP [`400`](../src/routes/price.ts#L55) Bad Request with validation details.
+
+---
+
+## Precision Guarantees
+
+### Database Storage Precision
+- **Prices and VWAPs**: Stored as PostgreSQL `DECIMAL(`[`36`](../prisma/schema.prisma#L20)`, `[`18`](../prisma/schema.prisma#L20)`)` with [`18`](../prisma/schema.prisma#L20) decimal digits of fractional scale.
+- **Stellar Native Reserves & Volumes**: Stored as PostgreSQL `DECIMAL(`[`36`](../prisma/schema.prisma#L21)`, `[`7`](../prisma/schema.prisma#L21)`)` matching Stellar's native [`7`](../prisma/schema.prisma#L21) decimal place stroop scale ([`1`](../prisma/schema.prisma#L21) stroop = [`0.0000001`](../prisma/schema.prisma#L21) XLM).
+- **Enforcing Code**: [`prisma/schema.prisma`](../prisma/schema.prisma#L20)
+
+### API Boundary Serialization
+- **Standard Default Mode**: Returns numbers as IEEE-[`754`](../src/types.ts#L20) double precision floating-point numbers (~[`15`](../src/types.ts#L20)-[`17`](../src/types.ts#L20) significant digits).
+- **Exact String Representation Mode**: When negotiated via `X-Decimal-Format: string`, `Accept: application/json; decimals=strings`, or `?decimals=strings`, all decimal quantities serialise as exact strings without floating-point truncation.
+- **Enforcing Code**: [`prisma/schema.prisma`](../prisma/schema.prisma#L20), [`src/types.ts`](../src/types.ts#L20)
+- **Violation Behavior**: Consumers that require exact [`18`](../prisma/schema.prisma#L20)-decimal precision must negotiate string format; unnegotiated requests receive standard JSON numbers for backward compatibility.
+
+---
+
+## Venue Inclusion Guarantees
+
+Lens integrates [`4`](../src/ingest/venues/index.ts#L19) registered venue adapters:
+
+| Venue | Identifier | Kind | Testnet | Mainnet | Included In | Enforcing Code |
+|---|---|---|---|---|---|---|
+| **Stellar Decentralized Exchange (SDEX)** | `sdex` | `orderbook` | Enabled | Enabled | VWAP, Best Route, Depth, Book, Volumes, Spreads | [`src/ingest/venues/sdex.ts`](../src/ingest/venues/sdex.ts#L174) |

+
+- **Reflector Oracle**: Used optionally for oracle benchmark comparison (`/compare/:asset`) and GraphQL oracle resolution. Disabled by default unless configured.
+- **Enforcing Code**: [`src/ingest/venues/index.ts`](../src/ingest/venues/index.ts#L19), [`src/config.ts`](../src/config.ts#L171)
+
+---
+
+## Violation Semantics Summary
+
+When a data quality guarantee is breached, Lens behaves deterministically:
+
+- **Stale Observation (age >= [`300`](../src/aggregator/vwap.ts#L4) s)**: Returns the last known price marked with `stale: true` and downgraded confidence (`low`), preserving availability while warning callers.
+- **Missing Ingestion / Empty Window (trades = [`0`](../src/aggregator/vwap.ts#L185))**: Returns `confidence: "unknown"` with `lastTradeAgeSeconds: null`, falling back through VWAP [`1`](../src/aggregator/vwap.ts#L198)h -> VWAP [`24`](../src/aggregator/vwap.ts#L198)h -> AMM Spot -> [`0`](../src/aggregator/vwap.ts#L198).
+- **Unwatched Pair**: Returns HTTP [`404`](../src/api/rest.ts#L111) Not Found with `{ "error": "Pair <A>/<B> not watched on <network>" }`.
+- **Invalid Query Parameters**: Returns HTTP [`400`](../src/routes/price.ts#L55) Bad Request with structured Zod validation errors.
+- **Outbound Failure / Ingestion Silence (>= [`300000`](../src/routes/venues.ts#L7) ms)**: Venue liveness degrades from `'live'` to `'stale'`.
+- **Rate Limit Exceeded**: Returns HTTP [`429`](../src/app.ts#L107) Too Many Requests.

-# Database migrations
-
-Issue **#233**. Before this, `prisma/` contained only `schema.prisma` — there was
-no `migrations/` directory, and every schema change was applied with
-`prisma db push`. Lens now uses **`prisma migrate`**: schema changes are
-committed as reviewable SQL, and deployments apply them with `migrate deploy`.
-
-## Why not `db push`
-
-`prisma db push` diffs the *live* database against `schema.prisma` and applies
-whatever it decides, on the spot. That gives you none of the things a service
-that holds money-moving data needs:
-
-- **Nothing is reviewable.** A schema change is whatever the diff produced at
-  that instant, not a file a reviewer read.
-- **No reproducible deploy.** Two environments pushed at different times can
-  land on different shapes; nothing in the repo describes the live shape.
-- **No rollback.** There is no record of what changed, so there is nothing to
-  undo. With `--accept-data-loss` a push can silently drop a column.
-- **It has already bitten us.** A `db push` in the sibling service half-applied
-  and left the database on a shape no commit described. That is exactly the
-  failure `prisma migrate` exists to prevent.
-
-So: **do not run `prisma db push` against any environment.** It is no longer a
-`package.json` script. The `db push` call at app startup (`src/index.ts`) now
-runs `migrate deploy` instead.
-
-## What lives in the repo now
-
-```
-prisma/
-  schema.prisma                     # the source of truth for the data model
-  migrations/
-    migration_lock.toml             # provider = "postgresql" (do not hand-edit)
-    0_init/
-      migration.sql                 # baseline: recreates the production schema exactly
-```
-
-`0_init/migration.sql` is the **baseline** — the SQL that reproduces the current
-production schema from an empty database. It is generated, not hand-written:
-
-```bash
-prisma migrate diff \
-  --from-empty \
-  --to-schema-datamodel prisma/schema.prisma \
-  --script > prisma/migrations/0_init/migration.sql
-```
-
-## Daily workflow (local development)
-
-Edit `schema.prisma`, then generate a migration. Do **not** `db push`.
-
-```bash
-npm run db:migrate        # prisma migrate dev — creates and applies a new migration
-```
-
-`migrate dev` writes a new timestamped folder under `prisma/migrations/`.
-**Commit that folder.** It is now the reviewable record of the change.
-
-```bash
-npm run db:status         # which migrations are applied / pending
-npm run db:reset          # drop schema and re-apply all migrations (NEVER on prod)
-```
-
-## Deploying
-
-Deploys apply committed migrations only — they never diff the live database:
-
-```bash
-npm run db:deploy         # prisma migrate deploy
-```
-
-App startup (`src/index.ts`) runs `migrate deploy` for you, so a container that
-starts against a database with pending migrations applies them and only them,
-deterministically, or fails loudly if the database is ahead of the code.
-
-### Adopting the baseline on an EXISTING database
-
-Every Lens database that exists today was created by `db push`: it already
-matches `schema.prisma` and has no `_prisma_migrations` table. The baseline's
-`CREATE TABLE` statements must **not** be re-run there — `migrate deploy` would
-collide with the tables that are already present and exit non-zero, which from
-`src/index.ts` (`main().catch(… process.exit(1))`) is a crash loop, not a failed
-migration.
-
-**Startup does this adoption for you.** `applyMigrations()` in
-`src/db/migrate.ts` asks the database one question before deploying — does
-`_prisma_migrations` exist, and does `price_points` exist — and when the schema
-is there without the history it records the baseline as applied *without
-executing it* before deploying:
-
-```bash
-prisma migrate resolve --applied <baseline>   # records it; runs no SQL
-prisma migrate deploy                          # then applies what is pending
-```
-
-So no manual step gates the deploy, and the order in which the merge and the
-redeploy happen cannot take the API down. The three states it distinguishes —
-empty database, pre-migrate database, already-adopted database — are pinned by
-`tests/db-migrate-baseline.test.ts`.
-
-Running `npx prisma migrate resolve --applied 0_init` by hand first is still
-perfectly fine; startup then finds the history and skips the adoption. The
-baseline is committed separately, rather than generated on deploy, precisely so
-that it can be recorded instead of run.
-
-### One-time check before the first deploy
-
-Adoption records "this database matches the baseline" permanently. It is only
-true if the database really does match `schema.prisma` — and `db push` is what
-used to make that true on every boot, silently. Dropping `db push` means a
-column that is in `schema.prisma` but not in the live database **stays
-missing**: `migrate deploy` has nothing pending to apply, and
-`assertSchemaValid()` only covers the five core tables in
-`EXPECTED_SCHEMA` (`src/db/schemaVerify.ts`), so a drifted `api_keys` or
-`webhooks` column would not be caught at startup — it would surface as 500s on
-the routes that read it.
-
-So run this once against each live database, before the first deploy on this
-commit, and read the output rather than the exit code:
-
-```bash
-# Differences between the LIVE database and schema.prisma, as SQL.
-# Empty output = the database matches the baseline and is safe to adopt.
-DIRECT_DATABASE_URL='<direct url for that environment>'   npx prisma migrate diff     --from-schema-datasource prisma/schema.prisma     --to-schema-datamodel prisma/schema.prisma     --script
-```
-
-If it prints statements, do not adopt yet. Either apply them as a committed
-migration (`npm run db:migrate`, then `migrate deploy`), or converge the
-database on the previous commit — the one that still ran `db push` — and
-re-check.
-
-Two caveats on reading that output:
-
-- It is **not** wired into startup on purpose. Lens shares a Postgres instance
-  with the sibling indexer, and if the two ever land in the same schema this
-  diff reports the sibling's tables as drift. A false positive here would be a
-  refusal to boot, so the judgement stays with a person.
-- The CI `db-migrations` job does not cover this either. It replays the
-  migrations against an empty Postgres and diffs *that* against
-  `schema.prisma`; it never sees a live database, so it cannot tell you whether
-  production matches the baseline. Only the command above can.
-
-## The CI drift guard
-
-The `db-migrations` job in `.github/workflows/ci.yml` brings up a Postgres
-service and runs:
-
-- `scripts/db-drift-check.sh` — deploys every committed migration, then
-  `migrate diff --from-migrations prisma/migrations --to-schema-datamodel
-  prisma/schema.prisma --exit-code` against a shadow database. It exits non-zero
-  — failing CI — whenever `schema.prisma` and `prisma/migrations` disagree. This
-  is the check that would have caught a half-applied `db push`.
-- `scripts/db-migration-cycle.sh` — proves a new migration can be generated,
-  applied and rolled back on a clean database, and that the drift guard actually
-  fires on an un-migrated schema change.
-
-The DB-free unit test `tests/prisma-migrations.test.ts` (part of `npm test`)
-additionally locks the **baseline** to `schema.prisma`: it fails while the repo
-has no migration history, and fails if you edit the schema without regenerating
-the baseline, so a missing migration is caught even without a database.
-
-Run the database-backed checks locally against the compose Postgres:
-
-```bash
-docker compose up -d postgres
-# create an empty shadow database alongside `lens`
-DATABASE_URL=postgresql://lens:lens@localhost:5432/lens \
-DIRECT_DATABASE_URL=postgresql://lens:lens@localhost:5432/lens \
-SHADOW_DATABASE_URL=postgresql://lens:lens@localhost:5432/lens_shadow \
-  npm run db:drift-check
-```
-
-## Rolling back a bad migration
-
-Prisma does not generate down-migrations. In a **non-production** environment,
-`npm run db:reset` drops the schema and re-applies every committed migration,
-which is the clean, reproducible way to back out of a half-applied change. In
-production, roll forward: commit a new migration that reverses the change and
-`migrate deploy` it. Either way the history in `prisma/migrations/` is the
-source of truth — the thing `db push` never gave us.

-   Running complex automated migrations inside container entrypoints poses locking hazards when running horizontally scaled nodes against shared PostgreSQL databases. Decoupling schema validation from schema migration prevents distributed boot race conditions.
-
-3. **Time-Series Partitioning Compatibility:**
-   Lens's high-frequency tables (such as `price_points` and `price_aggregates`) require composite primary keys (e.g. `[id, timestamp]`) and time-series optimizations.

-
-To ensure that running code never crashes at request time due to missing columns or unapplied schema changes:

-- It performs a low-overhead inspection against PostgreSQL `information_schema.tables` and `information_schema.columns`.
-- If an expected table or column is absent, it fails fast and names the missing entities.
-- `/ready` and `/status` can query `verifyDatabaseSchema()` to isolate instances before they receive live traffic.

-When moving to formal multi-region enterprise production deployments:

-| **GraphQL Query Endpoint** | HTTP POST / GET | `http://localhost:3002/graphql` | Executes GraphQL queries and introspections. |
-| **GraphiQL Browser IDE** | HTTP GET | `http://localhost:3002/graphiql` | Interactive in-browser GraphQL explorer with auto-completion. |
-| **GraphQL Subscription Endpoint** | WebSocket (`ws://` / `wss://`) | `ws://localhost:3002/graphql` | Real-time streaming price updates over WebSocket using `graphql-transport-ws`. |

-> [!IMPORTANT]
-> **WebSocket Subprotocol Requirement**: The subscription server requires the modern **@graphql-transport-ws** subprotocol (the standard implemented by [`graphql-ws`](https://github.com/enisdenjo/graphql-ws)). Legacy Apollo `subscriptions-transport-ws` is **not** supported and will be rejected during connection initialization.

-## Query depth limit
-
-Lens validates every HTTP GraphQL operation before execution. The default
-maximum is **3**, configurable with `GRAPHQL_MAX_QUERY_DEPTH` as a positive
-integer at server startup. An invalid value prevents startup rather than
-disabling the protection.

-Depth is the greatest number of field selections on a path from an operation
-root to a leaf; aliases and fragment syntax do not add depth, but fields reached
-through inline fragments and named fragment spreads do. For example,
-`oracle { oracles { name } }` has depth 3. An operation over the configured
-ceiling is rejected before any resolver runs with a normal GraphQL error such
-as `Query depth 4 exceeds the maximum allowed depth of 3.`
-
-Pure `__schema` and `__type` operations are exempt to preserve GraphiQL's
-standard introspection query. This exemption is deliberately root-scoped: a
-mixed operation still has every application-field path measured, so adding an
-introspection field cannot bypass the limit. Revisit the default when adding a
-legitimate application relationship deeper than three fields.

-## Schema & Types
-
-The complete, canonical Schema Definition Language (SDL) artifact is committed at [`schema.graphql`](../schema.graphql).
-It can be regenerated from code definitions using `npm run graphql:schema:gen`, and is continuously validated against drift in CI.
-
-### Root Operation Types
-
-```graphql

-### 3. `getPriceHistory`
-
-Retrieves historical aggregated price buckets (OHLCV and VWAP) for a given pair and timeframe window (`1m`, `5m`, `1h`, `24h`).
-
-`from` and `to` are optional ISO 8601 timestamps that constrain the query to an explicit time range. The range is **exclusive at the upper end** — a bucket is returned only if its start is `>= from` and `< to`. This is deliberately different from the REST `history` route, which is inclusive at both ends and thus double-counts boundary buckets across adjacent windows. When `from` omitted the range extends backward from `to` (or now) for at most `limit` buckets; when `to` omitted the range extends forward from `from` (or the oldest available bucket) to now. A `from` later than `to` is an error, as is a range that would produce more buckets than the server allows (the same cap the REST history route rejects as over-large).
-
-#### Query Definition
-```graphql
-query GetPairHistory($assetA: String!, $assetB: String!, $window: String!, $from: String, $to: String, $limit: Int) {

-## Live Price Subscriptions (`graphql-transport-ws`)
-
-Live price updates are streamed over WebSocket using the [`graphql-transport-ws`](https://github.com/enisdenjo/graphql-ws) subprotocol. The client must negotiate this subprotocol during the WebSocket handshake.
-
-### Protocol Handshake Walkthrough
-
-1. Open a WebSocket to `ws://localhost:3002/graphql` with the subprotocol `graphql-transport-ws`.
-2. Send a `connection_init`" message. The server replies with `connection_ack` on success.
-3. Send a `subscribe` message containing the GraphQL subscription document and variables.
-4. Receive `data` messages as price updates arrive.
-5. Send `complete` to unsubscribe, or close the socket.
-
-### Network Filtering Semantics
-
-The `priceUpdated` subscription accepts an optional `network` argument:
-
-- @omitted or `null`: receive updates from all networks.
-- `"testnet"`: receive only testnet updates.
-- `"mainnet" : receive only mainnet updates.
-
-### Runnable Client Example (Raw WebSocket & Handshake)
-
-```typescript
-import WebSocket from 'ws';
-
-const ws = new WebSocket('ws://localhost:3002/graphql', 'graphql-transport-ws');
-
-ws.on('open', () => {
-  ws.send(JSON.stringify({ type: 'connection_init' }));
-});
-
-ws.on('message', (raw) => {
-  const msg = JSON.parse(raw.toString());
-  if (msg.type === 'connection_ack') {
-    ws.send(JSON.stringify({
-      id: '1',
-      type: 'subscribe',
-      payload: {
-        query: `subscription PriceUpdates($pair: String!) { priceUpdated(pair: $pair) { pair price ts network } }`,
-        variables: { pair: 'USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPPPPRE34K4KZVN/XLM' },
-      },
-    }));
-  } else if (msg.type === 'data') {
-    console.log('price update', msg.payload.data.priceUpdated);
-  }
-});
-```
-
-### Runnable Client Example (`graphql-ws` Library)
-
-```typescript
-import { createClient } from 'graphql-ws';
-import WebSocket from 'ws';
-
-const client = createClient({
-  url: 'ws://localhost:3002/graphql',
-  webSocketImpl: WebSocket as any,
-});
-
-const unsubscribe = client.subscribe(
-  { query: `subscription PriceUpdates($pair: String!) { priceUpdated(pair: $pair) { pair price ts network } }`, variables: { pair: 'USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPPPPRE34K4KZVN/XLM' } },
-  { next: (data) => console.log('price update', data), error: console.error, complete: () => console.log('done') },
-);
-
-// Call unsubscribe() to stop the stream.

-## Capabilities & Gaps Against REST
-
-| Capability | REST `/prices/history` | GraphQL `getPriceHistory` |
-|---|---|---|
-| Explicit time range | `from` / `to` | `from` / `to` |
-| Boundary inclusivity | inclusive at both ends | exclusive at the upper (`to`) end |
-| Over-large range rejection | yes | yes (same cap) |
-| `from` after `to` is an error | yes | yes |
+# Lens GraphQL API Documentation
+
+Lens exposes a high-performance GraphQL API alongside its REST interface, powered by Fastify and [mercurius](https://mercurius.dev). It aggregates real-time and historical pricing data from the Stellar Classic Decentralized Exchange (SDEE) order book and Automated Market Maker (AMM) liquidity pools.

+## Endpoints & Access
+
+| Interface | Protocol | URL / Path | Description |
+|---|---|---|---|
+| **GraphQL Query Endpoint** | HTTP POST / GET | `http://localhost:3002/graphql` | Executes GraphQL queries and introspections. |
+| **GraphiQL Browser IDE** | HTTP GET | `http://localhost:3002/graphiql` | Interactive in-browser GraphQL explorer with auto-completion. |
+| **GraphQL Subscription Endpoint** | WebSocket (`ws://` / `wss://`) | `ws://localhost:3002/graphql` | Real-time streaming price updates over WebSocket using `graphql-transport-ws`. |
+
+> [!IMPORTANT]
+> **WebSocket Subprotocol Requirement**: The subscription server requires the modern **@graphql-transport-ws** subprotocol (the standard implemented by [`graphql-ws`](https://github.com/enisdenjo/graphql-ws)). Legacy Apollo `subscriptions-transport-ws` is **not** supported and will be rejected during connection initialization.
+
+## Query depth limit
+
+Lens validates every HTTP GraphQL operation before execution. The default
+maximum is **3**, configurable with `GRAPHQL_MAX_QUERY_DEPTH` as a positive
+integer at server startup. An invalid value prevents startup rather than
+disabling the protection.
+
+Depth is the greatest number of field selections on a path from an operation
+root to a leaf; aliases and fragment syntax do not add depth, but fields reached
+through inline fragments and named fragment spreads do. For example,
+`oracle { oracles { name } }` has depth 3. An operation over the configured
+ceiling is rejected before any resolver runs with a normal GraphQL error such
+as `Query depth 4 exceeds the maximum allowed depth of 3.`
+
+Pure `__schema` and `__type` operations are exempt to preserve GraphiQL's
+standard introspection query. This exemption is deliberately root-scoped: a
+mixed operation still has every application-field path measured, so adding an
+introspection field cannot bypass the limit. Revisit the default when adding a
+legitimate application relationship deeper than three fields.

+## Schema & Types

+## Queries & Runnable Examples
+
+All examples below can be executed directly against a running Lens instance. Canonical asset representations use standard Stellar format: native lumens as `XLM` or `native`, and issued assets as `CODE:ISSUER` (for example, Circle USDC on Stellar mainnet: `USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPPPRR34K4KZVN`)`.

+
+### 2. `getBestRoute`
+
+Simulates swap execution for an explicit order amount across both NDEX order books and AMM liquidity pools, calculating projected output tokens and slippage.
+
+#### Query Definition
+```graphql
+query GetBestExecutionRoute($assetA: String!, $assetB: String!, $amount: Float!) {

+
+### 3. `getPriceHistory`
+
+Retrieves historical aggregated price buckets (OHLCV and VWAP) for a given pair and timeframe window (`1m`, `5m`, `1h`, `24h`).
+
+`from` and `to` are optional ISO 8601 timestamps that constrain the query to an explicit time range. The range is **exclusive at the upper end** — a bucket is returned only if its start is `>= from` and `< to`. This is deliberately different from the REST `history` route, which is inclusive at both ends and thus double-counts boundary buckets across adjacent windows. When `from` omitted the range extends backward from `to` (or now) for at most `limit` buckets; when `to` omitted the range extends forward from `from` (or the oldest available bucket) to now. A `from` later than `to` is an error, as is a range that would produce more buckets than the server allows (the same cap the REST history route rejects as over-large).
+
+#### Query Definition
+```graphql
+query GetPairHistory($assetA: String!, $assetB: String!, $window: String!, $from: String, $to: String, $limit: Int) {
+  getPriceHistory(assetA: $assetA, assetB: $assetB, window: $window, from: $from, to: $to, limit: $limit) {

+
+Returns the canonical list of pair keys currently being tracked and priced by the service.

+
+#### Runnable `curl` Command

+## Live Price Subscriptions (`graphql-transport-ws`)
+
+Live price updates are streamed over WebSocket using the [`graphql-transport-ws`](https://github.com/enisdenjo/graphql-ws) subprotocol. The client must negotiate this subprotocol during the WebSocket handshake.
+
+### Protocol Handshake Walkthrough
+
+1. Open a WebSocket to `ws://localhost:3002/graphql` with the subprotocol `graphql-transport-ws`.
+2. Send a `connection_init`" message. The server replies with `connection_ack` on success.
+3. Send a `subscribe` message containing the GraphQL subscription document and variables.
+4. Receive `data` messages as price updates arrive.
+5. Send `complete` to unsubscribe, or close the socket.
+
+### Network Filtering Semantics
+
+The `priceUpdated` subscription accepts an optional `network` argument:
+
+- @omitted or `null`: receive updates from all networks.
+- `"testnet"`: receive only testnet updates.
+- `"mainnet" : receive only mainnet updates.
+
+### Runnable Client Example (Raw WebSocket & Handshake)
+
+```typescript
+import WebSocket from 'ws';
+
+const ws = new WebSocket('ws://localhost:3002/graphql', 'graphql-transport-ws');
+
+ws.on('open', () => {
+  ws.send(JSON.stringify({ type: 'connection_init' }));
+});
+
+ws.on('message', (raw) => {
+  const msg = JSON.parse(raw.toString());
+  if (msg.type === 'connection_ack') {
+    ws.send(JSON.stringify({
+      id: '1',
+      type: 'subscribe',
+      payload: {
+        query: `subscription PriceUpdates($pair: String!) { priceUpdated(pair: $pair) { pair price ts network } }`,
+        variables: { pair: 'USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPPPPRE34K4KZVN/XLM' },
+      },
+    }));
+  } else if (msg.type === 'data') {
+    console.log('price update', msg.payload.data.priceUpdated);
+  }
+});
+```
+
+### Runnable Client Example (`graphql-ws` Library)
+
+```typescript
+import { createClient } from 'graphql-ws';
+import WebSocket from 'ws';
+
+const client = createClient({
+  url: 'ws://localhost:3002/graphql',
+  webSocketImpl: WebSocket as any,
+});
+
+const unsubscribe = client.subscribe(
+  { query: `subscription PriceUpdates($pair: String!) { priceUpdated(pair: $pair) { pair price ts network } }`, variables: { pair: 'USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPPPPRE34K4KZVN/XLM' } },
+  { next: (data) => console.log('price update', data), error: console.error, complete: () => console.log('done') },
+);
+
+// Call unsubscribe() to stop the stream.
+```

+## Capabilities & Gaps Against REST
+
+| Capability | REST `/prices/history` | GraphQL `getPriceHistory` |
+|---|---|---|
+| Explicit time range | `from` / `to` | `from` / `to` |
+| Boundary inclusivity | inclusive at both ends | exclusive at the upper (`to`) end |
+| Over-large range rejection | yes | yes (same cap) |
+| `from` after `to` is an error | yes | yes |

-# Liveness and readiness
-
-`/status` is a health endpoint, but it answers neither question a platform
-actually asks, and the two are not the same question:
-
-| | Question | Consequence of a wrong answer |
-|---|---|---|
-| `/live` | Is this process wedged and in need of a **kill**? | Restarting healthy processes turns a dependency blip into a fleet-wide cold-start storm |
-| `/ready` | Should this process receive **traffic** yet? | Sending traffic to a process that cannot answer it |
-
-`/status` reads `indexer_state`, so it fails when Postgres is unreachable — which
-makes it useless as a liveness signal — and it says nothing about whether the
-process has finished booting. Both probes are public, exempt from rate limiting,
-and excluded from `http_requests_total` (see below).
-
-## `GET /live`
-
-```json
-{ "ok": true, "uptimeSeconds": 3600 }
-```
-
-Answers `200` as long as the event loop is turning — reaching the handler *is*
-the signal. It touches neither Postgres nor Redis, deliberately, and it stays
-healthy even when every dependency is down.
-
-That is the important property. A liveness probe that fails during a database
-outage has the orchestrator restarting every instance at the same moment, which
-turns a recoverable dependency outage into a cold-start storm during which
-nothing — including the instances that were healthy — can serve.
-
-`uptimeSeconds` lets an operator watching a restart loop tell restarts apart
-from a process that is wedged without being restarted.
-
-## `GET /ready`
-
-`200` with `ok: true` when the instance can serve, `503` with `ok: false`
-otherwise. The body is identical either way; `ok` and the status code together
-say whether to route traffic here.
-
-```json
-{
-  "ok": false,
-  "booted": false,
-  "checks": {
-    "postgres": { "status": "skipped", "latencyMs": 0, "reason": "not part of readiness" },

-  },
-  "checkedAt": "2026-10-19T10:00:00.000Z"
-}
-```
-
-### Before boot completes
-
-`app.listen()` runs part-way through `main()` (see `src/index.ts`), before the
-ingesters, the retention worker and the websocket fan-out have started. Between
-listening and those loops running, the process accepts requests it cannot yet
-answer correctly. So `/ready` reports unhealthy until `markBootComplete()` at
-the end of `main()`, and `/live` stays healthy throughout — a starting instance
-needs to be **held out of rotation**, not killed.
-
-While not booted, no dependency is probed at all: nothing can make a not-yet-
-booted process ready, so polling it costs nothing.
-
-### Dependency checks
-
-- **Postgres** — `SELECT to_regclass('public.indexer_state') IS NOT NULL`. One
-  cheap query that answers both reachability and whether migrations were
-  applied. Reachability alone would report a process with no tables as ready,
-  and every route that reads one would fail. `indexer_state` is the table
-  `/status` itself reads, so it is the exact dependency whose absence makes this
-  service unable to answer.
-- **Redis** — `PING`. Included by default because the snapshot retention worker
-  and the aggregate refresh queue are Redis-backed and stop silently when it is
-  gone.
-
-A dependency reports `up`, `down` or `skipped`, plus the probe's round-trip time
-and, when it is not `up`, a fixed reason phrase. The reason is never the raw
-error: a connection error carries the host and port, and this is a public
-endpoint. The underlying error is logged with full detail instead.
-
-### Cost of polling
-
-Platforms poll every few seconds, so:
-
-- each probe is bounded by `READINESS_TIMEOUT_MS` (default 2s) — deliberately
-  shorter than the house 10s outbound deadline, because a probe slower than its
-  own polling interval reports stale answers;
-- answers are cached for `READINESS_CACHE_MS` (default 2s) and concurrent
-  callers share one in-flight run, so a poll costs at most one round trip per
-  dependency per interval.
-
-`node-postgres` exposes no `AbortSignal` on `query()`, so a probe that exceeds
-its deadline returns `down` without cancelling the query underneath. The cache
-is what bounds that: at most one such outstanding query per interval, instead of
-one per poll.
-
-## Configuration
-
-| Variable | Default | Effect |
-|---|---|---|
-| `READINESS_REDIS_CHECK` | `true` | Set to `false` to leave Redis out of readiness |
-| `READINESS_TIMEOUT_MS` | `2000` | Deadline for a single dependency probe |
-| `READINESS_CACHE_MS` | `2000` | How long one readiness answer is reused |
-
-Set `READINESS_REDIS_CHECK=false` for a deployment that deliberately runs
-Redis-less. Startup already treats an unavailable Redis as non-fatal and serves
-prices uncached from Postgres (`src/index.ts`), so on such a deployment failing
-readiness would pull a perfectly healthy instance out of rotation.
-
-## Why these routes are not counted
-
-`/metrics`, `/live` and `/ready` are excluded from `http_requests_total` and
-`http_request_duration_seconds` (`EXCLUDED_ROUTES` in
-`src/middleware/httpMetrics.ts`). Each is polled on a fixed interval, so
-counting any of them puts a floor under the request rate that no amount of real
-traffic dropping could go below — and a real outage could not move the number it
-is meant to reveal.
-
-They are also allow-listed from rate limiting alongside `/status`
-(`PROBE_PATHS` in `src/app.ts`). A `429` during an incident would take an
-instance out of rotation exactly when its health matters most, and the platform
-would read "throttled" as "unhealthy".
-
-Both send `Cache-Control: no-store`: a cached readiness answer would keep
-routing traffic to an instance that has already gone away.
-
-`/status` is unchanged — it keeps its own cache policy, its own rate-limit

-[`src/metrics.ts`](../src/metrics.ts). The ingestion metrics have their own doc
-— [`ingest-metrics.md`](ingest-metrics.md) — because the label constraint there
-is different: they are labelled by `network` so the per-network ingester loops
-cannot overwrite each other's series.
-
-Request rate, error rate, latency, authentication failures and load shedding
-help answer "is the API healthy". The pre-existing `price_requests_total`
-counts price calls specifically and cannot answer that question; it is
-unchanged and still means what it always meant.
-
-The same cardinality rule applies to every metric family: labels must come from
-fixed buckets or server-defined values. Never put raw request paths, asset
-codes, issuer addresses, query values or websocket subscription strings in a
-Prometheus label.
-
-## What is exported
-
-### `http_requests_total`
-
-Counter. Labels: `method`, `route`, `status_class`.
-
-| Label | Values | Notes |
-| --- | --- | --- |
-| `method` | `GET`, `POST`, … | The HTTP method. |
-| `route` | `/price/:assetA/:assetB`, `/status`, … | The matched Fastify route **template**, never the resolved URL. Unrouted requests get the literal `unmatched`. |
-| `status_class` | `2xx`, `3xx`, `4xx`, `5xx` | The status class, not the exact code. |
-
-### `http_request_duration_seconds`
-
-Histogram. Labels: `method`, `route`.
-
-Buckets: `0.005, 0.01, 0.025, 0.05, 0.1, 0.25, 0.5, 1, 2.5, 5, 10`.
-
-Observed for every request that produces a response, successful or not.
-
-### `api_key_auth_failures_total`
-
-Counter. Label: `reason`, with the bounded values `missing`, `malformed`,
-`unknown`, `revoked` and `expired`. The `reason` value matches the
-machine-readable `code` in the corresponding API-key 401 response.
-
-### `admin_auth_failures_total`
-
-Counter. No labels. This tracks rejected authentication attempts on admin
-routes independently of API-key failures.
-
-### Rate-limit counters
-
-`rate_limit_rejections_total` is a counter labelled by the bounded `scope`
-values `key` and `ip`; it counts requests rejected by the per-key or fallback
-IP limiter. Those requests return HTTP 429 and code `PER_KEY_RATE_LIMITED` or
-`IP_RATE_LIMITED`.
-
-`global_shed_requests_total` is an unlabeled counter for requests shed by the
-per-instance global ceiling. Those requests return HTTP 503 with code
-`GLOBAL_RATE_LIMITED`.
-
-Authentication metrics never include keys, hashes, tokens, key prefixes or
-caller addresses as labels.
-
-## Global request ceiling
-
-`GLOBAL_RATE_LIMIT_MAX` configures the maximum accepted non-health requests
-per rolling 60-second window on each instance; it defaults to `1000` and must
-be a positive integer. The global check runs after the per-key/IP limiter, so
-per-key 429 responses remain distinct and are not counted against the global
-ceiling.
-
-At 80% of the ceiling, rounded up, the service starts shedding expensive
-route templates (GraphQL, price, route, pools, candles, history, screener,
-benchmark, oracle, compare, basket, venues, spreads, volumes, book, verify
-and settle) to preserve room for other routes. Once the ceiling is full, it
-sheds all non-health routes.
-`/status`, `/live` and `/ready` are always exempt. Shed requests include a
-`Retry-After` header.
-
-The ceiling is **per instance**, not deployment-wide. With `N` equally
-configured instances the approximate aggregate ceiling is
-`GLOBAL_RATE_LIMIT_MAX x N`; choose the per-instance value based on instance
-capacity and expected autoscaling so scaling out does not imply a higher
-deployment-wide traffic budget than intended.
-
-## Why the labels look like this
-
-Cardinality is the whole design constraint. A histogram labelled by `req.url`
-would mint a new time series for every asset pair, every address and every
-cursor Lens is asked about — an unbounded set driven by callers, which
-eventually degrades the Prometheus instance scraping it.
-
-So:
-
-- **`route` is the route template.** Fastify exposes the matched route on
-  `req.routeOptions.url`; that is what is used. 100 requests to 100 distinct
-  addresses produce **one** series, not 100 — asserted in
-  [`tests/httpMetrics.test.ts`](../tests/httpMetrics.test.ts).
-- **Unmatched requests collapse to `unmatched`.** A 404 uses the literal string
-  rather than the raw path, so a scanner probing a thousand URLs cannot mint a
-  thousand series.
-- **`status_class`, not `status`.** This bounds the series count at
-  `methods x routes x 5` rather than `methods x routes x ~60`. If a concrete
-  need for an exact code appears, add it then — it is easy to add a label and
-  painful to remove one dashboards depend on.
-- **Websocket pairs use fixed buckets.** `ws_clients_total`,
-  `ws_messages_sent_total`, `ws_messages_dropped_total` and
-  `ws_clients_dropped_total` retain their `pair` label, but pair-specific
-  subscriptions are recorded as `other`; `*` remains the aggregate across all
-  subscriptions. Arbitrary pair names and issuer addresses stay in fanout state
-  only and cannot create Prometheus series. `ws_buffered_bytes` is aggregate-only
-  (`*`): one series per connected client would be unbounded cardinality driven by
-  caller-supplied subscription strings. See
-  [`websocket-backpressure.md`](websocket-backpressure.md).
-
-## Excluded routes
-
-`/metrics`, `/live` and `/ready` are not counted at all (`EXCLUDED_ROUTES` in
-[`src/middleware/httpMetrics.ts`](../src/middleware/httpMetrics.ts)). Each is
-polled on a fixed interval — by the scraper for the first, by the platform for
-the other two — so counting any of them would have the poller continuously
-inflate the very numbers it is reading. Request rate could never fall to zero on
-an idle service, and a real outage could not move it, which is the opposite of
-what these two metrics are for. See [`health.md`](health.md).
-
-## Bucket choice
-
-The prom-client defaults cluster below 1s and suit fast in-process handlers.
-Lens handlers are not that: a request does a Redis cache lookup (single-digit
-ms) or, on a miss, a Postgres aggregate query plus — for `/price` and `/route` —
-Horizon/Soroswap network round-trips.
-
-The buckets therefore give resolution in two regions:
-
-- **5ms–50ms** — cache hits, the common fast path. Enough granularity to see the
-  Redis path regress before users notice.
-- **100ms–2.5s** — DB aggregates and upstream venue calls. This is where p95
-  actually lives and where an SLO would be set.
-
-The 5s and 10s buckets catch upstream stalls short of a timeout. Anything slower
-lands in `+Inf` and surfaces as a saturated p99.
-
-## Registration order
-
-The hook is registered **first** in [`src/index.ts`](../src/index.ts) — ahead of
-the network selector, API-key auth, the rate limiter and x402.
-
-This matters. All of those reject requests from an `onRequest` hook, and Fastify
-runs `onRequest` hooks in registration order. Registering the metrics plugin
-later would mean a request rejected by auth or x402 short-circuits before the
-timer starts, losing exactly the 401/402/429 traffic an operator most wants to
-see.
-
-`/metrics` itself is excluded from counting. It is scraped on a fixed interval,
-so counting it would have the scraper continuously inflate the numbers it is
-reading — request rate would never fall to zero on an idle service. `/live` and
-`/ready` are excluded for the same reason, polled by a different timer.
-

-
-A note on `LensHighErrorRate`: the ratio is undefined when there is no traffic,
-which is why `LensNoTraffic` exists separately rather than trying to make one
-rule cover both. A service serving zero requests is a real problem that an error
-*ratio* will never fire on.

-# HTTP Status Code Conventions
-
-This document defines the consistent rules for HTTP status codes across all Lens API routes.
-
-## The Rule
-
-**404 Not Found** is returned when:
-- A **resource does not exist** (the requested entity is not configured, not registered, or fundamentally absent)
-- Examples: pair not watched, API key not found, webhook subscription ID not found
-
-**200 OK with empty result** is returned when:
-- A **query matched nothing** (the resource exists and the query was valid, but no data satisfied the filters/time range)
-- Examples: no price data in the requested time window, no trades in the last 24h, no pools for the given asset
-
-**400 Bad Request** is returned when:
-- Request parameters are malformed, out of range, or violate validation rules
-- Examples: invalid date format, unsupported window value, negative amount
-
-## Application per Route
-
-### Routes returning 404 for non-existent resources
-
-| Route | 404 Condition |
-|---|---|
-| `GET /price/:assetA/:assetB` | Pair not watched on the requested network |
-| `GET /price/:assetA/:assetB/route` | Pair not watched on the requested network |
-| `GET /price/:assetA/:assetB/depth` | Pair not watched on the requested network |
-| `GET /benchmark/:asset` | Pair not watched on the requested network |
-| `DELETE /admin/keys/:id` | API key ID not found |
-| `DELETE /webhooks/:id` | Already 204 (idempotent deletion) |
-
-### Routes returning 200 with empty result + reason
-
-| Route | Empty Result Condition | Response Shape |
-|---|---|---|
-| `GET /basket` | One or more assets have no price data | `{ error: "No price data found for: ASSET1, ASSET2" }` **→ Changed to 200** |
-| `GET /compare/:asset` | No Lens or Reflector price available | `{ lens: null, reflector: null, status: "no_data", ... }` **→ Changed to 200** |
-| `GET /candles/:assetA/:assetB` | No trades in the requested time range | `{ candles: [], pairKey, interval, from, to }` |
-| `GET /price/:assetA/:assetB/history` | No aggregated buckets for the window | `{ buckets: [], pairKey, window }` |
-| `GET /spreads/:asset` | No venue quoted the asset in the window | `{ venues: [], tightest: null, ... }` |
-| `GET /volumes/:asset` | No trades for the asset in the window | `{ totalVolume: 0, byVenue: {}, venues: [], tradeCount: 0, ... }` |
-| `GET /screener` | No pairs matched the filters | `{ data: [], nextCursor: null, hasMore: false, total: null }` |
-| `GET /pools` | No pools for the network | `{ pools: [] }` |
-| `GET /pairs` | No watched pairs (configuration issue) | `{ pairs: [] }` |
-
-### Rationale
-
-The distinction preserves semantic information that a single status code cannot carry:
-
-- **404** tells the client "you asked for something that cannot exist — check your configuration or endpoint"
-- **200 + empty** tells the client "your request was valid but there is no data right now — try again later or widen your filters"
-
-A client that retries a 404 without changing its request is wasting resources. A client that retries a 200-empty after waiting or adjusting filters is behaving correctly.
-
-### Migration notes
-
-Routes that **changed** from 404 to 200-empty:
-- `/basket` — was 404 when an asset had no price; now 200 with `{ error: ... }` listing the missing assets
-- `/compare/:asset` — was 404 when both sources were null; now 200 with `status: "no_data"`
-
-Routes that were **already correct** and unchanged:
-- `/candles`, `/price/*/history`, `/spreads`, `/volumes`, `/screener`, `/pools`, `/pairs` — all return 200 with empty arrays
-- `/price`, `/price/*/route`, `/price/*/depth`, `/benchmark` — all return 404 for unwatched pairs

+| `GET /pairs` | No watched pairs (configuration issue) | `{ pairs: [] }` |
+
+### Rationale
+
+The distinction preserves semantic information that a single status code cannot carry:
+
+- **404** tells the client "you asked for something that cannot exist — check your configuration or endpoint"
+- **200 + empty** tells the client "your request was valid but there is no data right now — try again later or widen your filters"
+
+A client that retries a 404 without changing its request is wasting resources. A client that retries a 200-empty after waiting or adjusting filters is behaving correctly.
+
+### Migration notes
+
+Routes that **changed** from 404 to 200-empty:
+- `/basket` — was 404 when an asset had no price; now 200 with `{ error: ... }` listing the missing assets
+- `/compare/:asset` — was 404 when both sources were null; now 200 with `status: "no_data"`
+
+Routes that were **already correct** and unchanged:
+- `/candles`, `/price/*/history`, `/spreads`, `/volumes`, `/screener`, `/pools`, `/pairs` — all return 200 with empty arrays
+- `/price`, `/price/*/route`, `/price/*/depth`, `/benchmark` — all return 404 for unwatched pairs

-# Ingest metrics
-
-The ingestion side of `/metrics`, defined in [`src/metrics.ts`](../src/metrics.ts).
-The HTTP layer has its own doc — [`http-metrics.md`](http-metrics.md) — because
-its label design is a separate problem. Everything here shares one concern:
-**Lens runs one ingester set per enabled network against a single Prometheus
-registry, so an ingest metric that cannot tell the networks apart is reporting
-nonsense on any deployment with more than one.**
-
-## What is exported
-
-| Metric | Type | Labels |
-| --- | --- | --- |
-| `trades_ingested_total` | Counter | `pair`, `network` |
-| `amm_snapshots_total` | Counter | `pool`, `network` |
-| `price_snapshots_total` | Counter | `network` |
-| `last_trade_timestamp` | Gauge | `pair`, `network` |
-
-| Label | Values | Notes |
-| --- | --- | --- |
-| `network` | `testnet`, `mainnet` | The `NetworkName` of the ingester loop that produced the sample, not the process-wide `STELLAR_NETWORK`. |
-| `pair` | `XLM/USDC`, … | The `pairKey` already used everywhere else in Lens. |
-| `pool` | Horizon liquidity-pool id | Pre-existing label, only on `amm_snapshots_total`. |
-
-All four are also emitted with the registry-wide `app="lens"` default label.
-
-## Why `network` is on all four
-
-Before this change, the ingest metrics were network-blind. On a dual-network
-deployment the two loops wrote to the same series.
-
-For the counters that is a silent merge — `trades_ingested_total` summed
-testnet and mainnet trades together, so a per-network ingest rate was not
-queryable at all.
-
-`last_trade_timestamp` was worse. It is a `Gauge.set()`, not an increment, so
-whichever loop ticked last won. The testnet loop at
-[`src/ingesters/sdex.ts`](../src/ingesters/sdex.ts) overwrote mainnet's value
-for the same pair every poll interval, and the series reported a timestamp
-belonging to exactly one network while looking network-agnostic. That is the
-only staleness signal Lens exports, and on a dual-network deployment it was
-unusable for the job — silently, because the value still looked like a plausible
-timestamp.
-
-Each call site now passes the `network` argument it already receives
-(`ingestPair(pair, network)`, `snapshotPool(pool, pair, network)`,
-`ingestPoolTrades(pool, pair, network)`, `appendSnapshots(now, network)`).
-The invariant is the loop's own network, never `activeNetwork` — `activeNetwork`
-is a per-process constant and is exactly the value that made this bug invisible.
-
-[`tests/ingestMetrics.test.ts`](../tests/ingestMetrics.test.ts) asserts that two
-networks produce two distinct series for the same pair rather than one
-overwritten one, and drives the real ingesters so a call site that forgets the
-label fails the test.
-
-## Cardinality
-
-Series count is `pairs x networks`:
-
-- `trades_ingested_total` and `last_trade_timestamp` — `pairs x networks`. Both
-  factors are bounded by configuration: `WATCHED_PAIRS` and `ENABLED_NETWORKS`
-  are single-digit, so this is tens of series, not thousands.
-- `amm_snapshots_total` — `pools x networks`. Pools are discovered from Horizon
-  for the configured pairs only, so this stays bounded by the same watch list.
-- `price_snapshots_total` — `networks`. One series per network, full stop.
-
-**Do not add `issuer` to any of these.** It would multiply the series count by
-every distinct token in the config for no gain: `pair` is the `pairKey` and
-already identifies the instrument, and any question that genuinely needs the
-issuer is a database question, not a Prometheus one. An issuer label is also the
-label most likely to be added casually — every token *looks* like a useful
-dimension until you count them.
-
-**Do not add `pool` to `trades_ingested_total` or `last_trade_timestamp`.**
-Pool ids are only known to the AMM loop, and adding them there would mean the
-SDEX loop needs a synthetic value; worse, it would turn a per-pair signal into
-a per-pool one. If pool-level trade volume is genuinely needed, derive it from
-`price_points` in the database, or add a separate metric with a deliberate label
-set rather than widening an existing one. It is easy to add a label and painful
-to remove one dashboards have come to depend on.

-```
-
-## Suggested alerts
-
-`time() - last_trade_timestamp` needs a threshold per pair, not one global one:
-a thin pair legitimately goes hours without a trade. The expression below is a
-starting point — tune it against the observed trade frequency of the pairs you
-actually watch before paging anyone.
-
-```yaml
-groups:
-  - name: lens-ingest
-    rules:
-      - alert: LensIngestStale
-        expr: |
-          (time() - last_trade_timestamp) > 3600
-            and on (pair, network)
-          (sum(increase(trades_ingested_total[6h])) by (pair, network) > 0)
-        for: 15m
-        labels: { severity: warning }
-        annotations:
-          summary: "{{ $labels.pair }} on {{ $labels.network }} has seen no trade for over an hour"
-```
-
-The `increase(...) > 0` arm is what makes this alertable rather than noisy: it
-fires only for pairs that were actually trading recently enough to be expected
-to trade again, so a pair that never trades does not page anyone. Adding
-`network` to the label set is what makes the `and on (pair, network)` join
-correct — without it the two networks' series are indistinguishable and the
-threshold can be satisfied or violated by whichever network happens to be
-active.

-# Live Service Spec Validation
-
-## Background
-`tests/openapi.test.ts` ensures that all registered routes are present in [`openapi.yaml`](../openapi.yaml). However, static routing coverage alone does not guarantee that the live deployed service actually responds with payloads that match the schemas published in the specification.
-
-This scheduled validation job queries every documented endpoint on the live service and validates the response payloads against their respective OpenAPI 3.0 schemas.
-
----
-
-## Acceptance Criteria & Architecture
-
-1. **Every documented route is validated against the live response**
-   - The validator parses `openapi.yaml` and executes test requests for each documented path and operation.
-   - Dynamic path templates (`{assetA}`, `{assetB}`, `{asset}`, `{id}`, `{keyId}`) and query parameters are populated with standard valid test arguments.
-   - Responses are validated against the declared JSON schemas in `components.schemas` using Ajv.
-
-2. **Failures are reported in one place that updates rather than multiplying**
-   - Instead of opening a new issue on every nightly run (which creates notification fatigue and leads teams to ignore alerts), the check:
-     - Searches for an existing issue labeled `live-spec-report`.
-     - Appends the latest run report as a timestamped comment and updates the main issue body with the current health banner.
-     - Creates the single tracking issue only if one does not already exist.
-     - Also publishes the report to `$GITHUB_STEP_SUMMARY` for direct visibility in the Actions UI.
-
-3. **A deliberate schema mismatch is detected by the check**
-   - Verified by automated tests in [`src/__tests__/liveSpecValidation.test.ts`](../src/__tests__/liveSpecValidation.test.ts).
-   - If a response field has the wrong type (e.g. `string` instead of `number`), is missing a required property, or provides an invalid enum value, the validator flags the route, identifies the invalid JSON path, and details the exact schema violation.
-
-4. **The job's schedule and its cost are documented**
-   - See [Schedule and Cost Analysis](#schedule-and-cost-analysis) below.
-
-5. **Reports rather than fails the build**
-   - Because live network conditions, temporary provider downtime, or third-party outages are outside CI's control, the scheduled job logs drift and posts reports while exiting cleanly with status `0`.
-
----
-
-## Schedule and Cost Analysis
-
-### Execution Schedule
-- **Trigger:** Cron schedule at **`05:00 UTC daily`** (`0 5 * * *`) and on-demand via `workflow_dispatch`.
-- **Timing Rationale:** 
-  - `03:00 UTC`: Nightly database backups ([`.github/workflows/db-backup.yml`](../.github/workflows/db-backup.yml)).
-  - `04:00 UTC`: Automated price load test ([`.github/workflows/load.yml`](../.github/workflows/load.yml)).
-  - `05:00 UTC`: Off-peak live spec validation runs once previous nightly jobs have completed, preventing any overlapping resource contention.
-
-### Resource & Financial Cost
-- **GitHub Actions Compute:**
-  - Runtime: **~20 to 45 seconds** per run.
-  - Monthly compute: ~30 runs × 1 minute = **~30 runner minutes per month**.
-  - Cost: Free (public open-source repositories receive unlimited free Actions minutes; private accounts have a 2,000 minute/month free tier).
-- **Live Service Ingestion & Network Load:**
-  - Total HTTP requests per run: **~25 requests** (one per documented endpoint).
-  - Bandwidth: < 150 KB total per run.
-  - Server Impact: Less than 0.001% of daily capacity; completely negligible overhead.
-

-## Running Locally
-
-To validate a local or remote deployment against the spec:

-# Validate local server (defaults to http://localhost:3002)
-npm run spec:validate-live

-# MCP resources
-
-The Lens MCP server (`src/mcp/server.ts`) offers an agent two kinds of thing:
-
-- **Tools** — functions it calls to *do* something: `bazaar_search`,
-  `paid_call`, `lens_get_price`.
-- **Resources** — read-only content it attaches to its context once, instead of
-  re-fetching by calling a tool every turn.
-
-Resources are for the stable, cacheable facts *about the service itself*. Each
-has a fixed URI, an accurate MIME type, and freshness an agent can rely on.
-
-## Resource URIs
-
-| URI | MIME type | Contents | `lastModified` comes from |
-| --- | --- | --- | --- |
-| `lens://pairs` | `application/json` | The pairs Lens quotes on the configured network: `{ network, pairs: [{ pairKey, assetA, assetB }] }`. | the instant this process resolved its config |
-| `lens://venues` | `application/json` | The venues Lens reads from, each with its `source` and whether it is `enabled` here. | the instant this process resolved its config |
-| `lens://openapi.json` | `application/json` | The service OpenAPI 3 document, served verbatim. | the file's on-disk mtime |
-| `lens://status` | `application/json` | Network, Horizon/RPC URLs, venue enablement, watched-pair count, server name and version. | the read instant |
-
-A URI never changes shape. Adding a field to a payload is fine; renaming a URI,
-or reusing one for different content, is not.
-
-## Freshness
-
-Every resource reports two things, on `resources/list` and on `resources/read`:
-
-- **`version`** — `sha256:<hex>` over the exact bytes returned, in
-  `_meta.version`. A client compares it against the copy it cached, so it can
-  decide whether to re-read without diffing the text. Identical payload means an
-  identical version.
-- **`lastModified`** — ISO-8601, in `annotations.lastModified` on list and
-  `_meta.lastModified` on both. Omitted when a source has no notion of change
-  rather than filled in with something invented.
-
-`lens://status` embeds its own generation time, so every read is a new version.
-That is deliberate: status is defined by being current, and a version that
-survived two reads would be a lie about it.
-
-`resources/list` resolves each resource to compute this metadata instead of
-returning a static catalogue. These payloads are small and cheap, and stale
-freshness metadata is worse than none.
-
-## Refusals
-
-Reading a URI that does not exist throws an MCP `InvalidParams` error, and a
-resource source that fails throws `InternalError`. Neither is expressed as a
-tool-style `{ isError, code }` payload: `ReadResourceResult` has no such field,
-so a fabricated one would be parsed as a successful read.
-
-This is also why the resources work adds nothing to the `MCP_ERROR_CODES`
-vocabulary in `./codes.ts`. That vocabulary answers "why did the money or the
-fetch fail" — `ERR_URL_BLOCKED` for an address we will never reach,
-`ERR_HOST_NOT_ALLOWED` for a host we will not pay. "No such resource" is a
-different question, and the protocol already has a typed answer for it.
-
-## Overriding the sources
-
-The defaults read only `config` and the on-disk OpenAPI document — no database —
-for the same reason `createLensPriceQueries` lives in its own module: a process
-that has not opted into Lens's own price data should not pay for importing `pg`
-and Prisma just to list what the service watches. `lens://pairs` therefore
-reports the *declared* pair list for the network, not the process-wide runtime
-registry, matching what `lens_get_price` accepts.
-
-A host that does hold that state can inject its own descriptors, exactly as it
-injects `priceQueries`:
-
-```ts
-new BazaarMcpServer({
-  fetchWithPayment,
-  resources: [
-    {
-      uri: 'lens://pairs',
-      name: 'pairs',
-      title: 'Watched pairs',
-      description: 'Pairs Lens quotes, including those added at runtime.',
-      mimeType: 'application/json',
-      read: () => ({ data: { network, pairs: getActivePairs() } }),
-    },
-  ],
-});
-```
-
-## Configuration
-
-`MCP_OPENAPI_PATH` overrides which file `lens://openapi.json` serves. Unset, it
-is the `openapi.json` at the package root. Set it only when the document sits
-elsewhere, e.g. mounted separately in a container.

+| `lens://venues` | `application/json` | The venues Lens reads from, each with its `source` and whether it is `enabled` here. | the instant this process resolved its config |
+| `lens://openapi.json` | `application/json` | The service OpenAPI 3 document, served verbatim. | the file's on-disk mtime |
+| `lens://status` | `application/json` | Network, Horizon/RPC URLs, venue enablement, watched-pair count, server name and version. | the read instant |
+
+A URI never changes shape. Adding a field to a payload is fine; renaming a URI,
+or reusing one for different content, is not.
+
+## Freshness
+
+Every resource reports two things, on `resources/list` and on `resources/read`:
+
+- **`version`** — `sha256:<hex>` over the exact bytes returned, in
+  `_meta.version`. A client compares it against the copy it cached, so it can
+  decide whether to re-read without diffing the text. Identical payload means an
+  identical version.
+- **`lastModified`** — ISO-8601, in `annotations.lastModified` on list and
+  `_meta.lastModified` on both. Omitted when a source has no notion of change
+  rather than filled in with something invented.
+
+`lens://status` embeds its own generation time, so every read is a new version.
+That is deliberate: status is defined by being current, and a version that
+survived two reads would be a lie about it.
+
+`resources/list` resolves each resource to compute this metadata instead of
+returning a static catalogue. These payloads are small and cheap, and stale
+freshness metadata is worse than none.
+
+## Refusals
+
+Reading a URI that does not exist throws an MCP `InvalidParams` error, and a
+resource source that fails throws `InternalError`. Neither is expressed as a
+tool-style `{ isError, code }` payload: `ReadResourceResult` has no such field,
+so a fabricated one would be parsed as a successful read.
+
+This is also why the resources work adds nothing to the `MCP_ERROR_CODES`
+vocabulary in `./codes.ts`. That vocabulary answers "why did the money or the
+fetch fail" — `ERR_URL_BLOCKED` for an address we will never reach,
+`ERR_HOST_NOT_ALLOWED` for a host we will not pay. "No such resource" is a
+different question, and the protocol already has a typed answer for it.
+
+## Overriding the sources
+
+The defaults read only `config` and the on-disk OpenAPI document — no database —
+for the same reason `createLensPriceQueries` lives in its own module: a process
+that has not opted into Lens's own price data should not pay for importing `pg`
+and Prisma just to list what the service watches. `lens://pairs` therefore
+reports the *declared* pair list for the network, not the process-wide runtime
+registry, matching what `lens_get_price` accepts.
+
+A host that does hold that state can inject its own descriptors, exactly as it
+injects `priceQueries`:
+
+```ts
+new BazaarMcpServer({
+  fetchWithPayment,
+  resources: [
+    {
+      uri: 'lens://pairs',
+      name: 'pairs',
+      title: 'Watched pairs',
+      description: 'Pairs Lens quotes, including those added at runtime.',
+      mimeType: 'application/json',
+      read: () => ({ data: { network, pairs: getActivePairs() } }),
+    },
+  ],
+});
+```
+
+## Configuration
+
+`MCP_OPENAPI_PATH` overrides which file `lens://openapi.json` serves. Unset, it
+is the `openapi.json` at the package root. Set it only when the document sits
+elsewhere, e.g. mounted separately in a container.

-# SEP-40 oracle publisher
-
-Lens has always been an oracle **consumer**: it reads Reflector's prices and
-compares them with its own. Issue #222 is the other direction — Lens as an
-oracle **publisher**, exposing a [SEP-40](https://github.com/StellarCommunity/seps/blob/main/SEP-0040.md)
-compatible price feed that any Soroban contract can read.
-
-Two pieces make up the feature:
-
-| Piece | Where | What it does |
-| --- | --- | --- |
-| The feed | `oracle/contract/` | A Soroban contract implementing SEP-40's `PriceFeedTrait`, plus one provider-side write (`report`). |
-| The publisher | `src/publish/` | The process that decides **when** a Lens aggregate is worth a transaction, and writes it. Runs once per enabled network, next to the ingest loops. |
-
-SEP-40 standardises the *read* side only ("the exact mechanism of data reporting
-mechanism utilized by an oracle is out of scope of this SEP"), so `report` is
-Lens's own design and every other entry point is exactly the shape the spec
-defines.
-
----
-
-## 1. The contract
-
-`oracle/contract/src/lib.rs` — package `lens_sep40_oracle`.
-
-### 1.1 The SEP-40 read surface
-
-Declared names and signatures are the spec's, not adaptations:
-
-| Entry point | Signature | Lens's behaviour |
-| --- | --- | --- |
-| `base` | `() -> Asset` | The asset every price in the feed is denominated in. Set once at `initialize`. |
-| `assets` | `() -> Vec<Asset>` | Every asset that has ever been reported, in first-seen order. |
-| `decimals` | `() -> u32` | Scale of `PriceData.price`. Immutable. |
-| `resolution` | `() -> u32` | Tick period in seconds that timestamps are trimmed to. Immutable. |
-| `price` | `(Asset, u64) -> Option<PriceData>` | The newest record **at or before** the requested timestamp. |
-| `prices` | `(Asset, u32) -> Option<Vec<PriceData>>` | The last *n* records, newest first. |
-| `lastprice` | `(Asset) -> Option<PriceData>` | The current feed value. |
-| `last_report` | `(Asset) -> Option<Report>` | Lens-specific: provenance of the last write (see 1.4). |
-
-A deviation-triggered feed is deliberately non-uniform — there is no record at
-every tick — so `price(asset, timestamp)` answers with the value that was **in
-effect** at that time rather than looking for an exact match. That is the
-extrapolation SEP-40 asks an oracle to present, and it is why the feed can be
-consumed by contracts that assume a tick per resolution.
-
-### 1.2 Price encoding
-
-`PriceData.price` is an `i128` scaled by `decimals()`:
-
-```
-real_price = PriceData.price / 10^decimals()
-```
-
-`PriceData.timestamp` is unix **seconds**, and the contract enforces SEP-40's
-trimming rule on every write:
-
-```
-timestamp == floor(unix_now() / resolution()) * resolution()
-```
-
-A write whose timestamp is not a whole number of ticks is rejected
-(`TimestampNotAligned`), so a consumer can treat trimming as a guarantee instead
-of a convention. Lens trims on the way out (`trimTimestamp` in
-`src/publish/sep40.ts`) and the contract re-checks.
-
-Scaling is done through a decimal **string**, not a float multiply, because
-`0.29 * 1e14` is `28999999999999.996` — `BigInt()` of that throws and
-`Math.round()` of that puts `28999999999999` on chain. One decimal digit off is
-a price that is wrong by a factor of ten, so `scalePrice` refuses non-integer
-results, exponential notation, non-positive prices and values beyond `i128`.
-
-### 1.3 `None`, not an error
-
-SEP-40: "oracles should delegate error handling logic directly to consumer
-contracts". So the read side returns `None` — never a revert — for an asset the
-feed has never quoted, a timestamp before the first report, a `records` count of
-zero, and an empty history. A consumer that wants to distinguish "no data" from
-"bad request" has to ask for `last_report` or call `assets()`; a consumer that
-just wants to not settle on missing data checks for `None`.
-
-### 1.4 Provenance, beyond SEP-40
-
-SEP-40's `PriceData` has no room for "where did this come from", and Lens
-refuses to publish a number it cannot source. Every `report` therefore carries
-the venue names behind it:
-
-```rust
-pub struct Report {
-    pub price: i128,
-    pub timestamp: u64,       // SEP-40 feed timestamp
-    pub reported_at: u64,     // ledger close time of the write
-    pub reported_ledger: u32, // ledger the write landed in
-    pub source_count: u32,    // always venues.len()
-    pub venues: Vec<Symbol>,  // 'SDEX', 'AMM', 'aquarius_amm', 'soroswap_amm', …
-}
-```
-
-`source_count` is **derived** from the venue list rather than passed in, so the
-contract cannot store a price claiming more sources than it can name. An empty
-venue list is rejected (`NoVenues`), as is a list longer than `MAX_VENUES` (16).
-Venues are never blended: the aggregate `price` is a route-aware best quote and
-the list says which markets produced it, exactly as `/price/:a/:b` reports
-`bestRoute` and `sources`.
-
-`reported_at` and `reported_ledger` are what let a consumer apply the same
-staleness bar the HTTP API does: `lastprice.timestamp` says when the *market*
-tick happened, `last_report.reported_at` says when the feed *learned* it.
-
-### 1.5 Errors
-
-| Code | Name | Raised when |
-| --- | --- | --- |
-| 1 | `AlreadyInitialized` | `initialize` is called a second time. |
-| 2 | `NonPositivePrice` | `price <= 0`. |
-| 3 | `TimestampNotAligned` | `timestamp % resolution != 0`. |
-| 4 | `NotNewer` | `timestamp` is not strictly newer than the asset's last record. |
-| 5 | `TimestampInFuture` | `timestamp > env.ledger().timestamp()`. |
-| 6 | `NoVenues` | Empty venue list. |
-| 7 | `TooManyVenues` | More than `MAX_VENUES` names. |
-| 8 | `InvalidConfig` | `decimals == 0` or `resolution == 0` at `initialize`. |
-
-`NotNewer` and `TimestampInFuture` are what make a retried publish harmless: a
-replay of a tick that already landed is refused, and a publisher with a clock
-ahead of the ledger cannot hand consumers a price that never ages.
-
-### 1.6 Admin surface
-
-- `initialize(admin, base, decimals, resolution)` — one-shot, admin-authenticated.
-- `set_publisher(publisher)` — admin-authenticated; points `report` at the hot key.
-- `upgrade(new_wasm_hash)` — admin-authenticated; swaps the WASM **without
-  changing the contract address**, which SEP-40 requires ("smart contract
-  consumers should only be expected to change their price feed aggregator address
-  if they would like to change oracle providers").
-
-`report` authorizes exactly one address: the publisher when one is set, the
-admin otherwise. Tests assert both halves of that — that a write carrying no
-publisher authorization does not land, and that the address the feed demands is
-the publisher and not the transaction's signer.
-
-### 1.7 Storage
-
-Per asset: `Last` (one `PriceData`), `LastReport` (one `Report`) and `History`
-(newest-first, trimmed to `MAX_HISTORY = 64` records). The asset registry is one
-instance entry. Persistent entries extend their TTL on read and write
-(`TTL_THRESHOLD = 5_000`, `TTL_BUMP = 40_000` ledgers), and instance storage is
-extended at `initialize`, so an idle feed does not expire out from under its
-consumers.
-
----
-
-## 2. How a Lens pair becomes a feed value
-
-Lens stores a pair as **`price` = units of assetB per assetA**. SEP-40 quotes
-every asset against one **base**. `orientAgainstBase` in
-`src/publish/publisher.ts` reconciles the two from the base the *deployed
-contract* reports — never from an env var, because a mis-declared scale produces
-a price that is wrong by orders of magnitude and still reads fine:
-
-| Feed `base` | Quoted asset | Price published |
-| --- | --- | --- |
-| equals `assetB` | `assetA` | the stored number, as-is |
-| equals `assetA` | `assetB` | `1 / stored` (inverted) |
-| neither | — | pair skipped, reason recorded |
-
-Worked example, the default pair in `.env.example`: `XLM:native / USDC:GBBD47IF6LWK7P7MDEVSCWR7DPUWV3NY3DTQEVFL4NAT4AQH3ZLLFLA5`
-stores `price = USDC per XLM`. With `base = Other("USDC")`, `decimals = 14`, the
-feed quotes `Asset::Other("XLM")` directly — `0.025` becomes `250000000000000`.
-The same feed pointed at `base = Other("XLM")` would quote the USDC leg and
-publish `1 / 0.025 = 40` as `400000000000000000000`.
-
-A pair whose legs are neither of them is **not** published. Putting a ratio under
-the wrong asset label is worse than an empty feed, so the cycle records the
-reason (`base_not_in_pair`) and moves on.
-
-Asset identity follows SEP-40: an anchored asset is identified by the address of
-its **Stellar Asset Contract**, derived with
-`new Asset(code, issuer).contractId(passphrase)` — issuer-qualified by
-construction, so two tokens called USDC are two different assets. Native XLM has
-no asset contract and uses the spec's `Other(Symbol)` form. Contract addresses
-are derived from the issuer in `WATCHED_PAIRS_*`, never typed by hand. As one
-reference point, mainnet USDC (`GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN`)
-derives to `CCW67TSZV3SSS2HXMBQ5JFGCKJNXKZM7UQUWUZPUTHXSTZLEO7SJMI75`; the test
-suite asserts that derivation so a typo in the issuer cannot pass silently.
-**This document deliberately contains no Lens feed contract id** — it is created
-when the operator deploys `oracle/contract/` (§4), and a placeholder in the docs
-is how five deployments end up pointing at five different guesses.
-
----
-
-## 3. When Lens writes
-
-The policy is `src/publish/trigger.ts`, a pure function over
-(aggregate, what is already on chain, thresholds, clock). It exists because a
-tick is not an event: Lens polls every few seconds, and a publisher that wrote
-per sample would be a transaction spam bot that also publishes the noise between
-trades.
-
-Order matters, and it is what makes the acceptance criteria checkable:
-
-**Guards — evaluated first, before any chain read.**
-
-| Guard | Condition |
-| --- | --- |
-| `no_venue` | No venue name behind the number. "A price you cannot source is worse than no price." |
-| `invalid_price` | Zero, negative or non-finite. |
-| `no_observation` | No trade has ever been recorded for this pair **on this network**. |
-| `stale_aggregate` | The aggregator's own `stale` flag is set — the same signal `/price` reports, so the feed can never carry a price the API calls stale. |
-| `aggregate_too_old` | `lastTradeAgeSeconds > SEP40_MAX_AGE_SECONDS` (default 120). |
-
-`evaluateGuards` runs **before** `lastprice` is read. A stale aggregate needs no
-comparison to decide anything — it is simply not publishable — so a blocked tick
-provably touches no RPC and spends no fee. That is the "a stale aggregate is
-never published" criterion as a code path, not as a promise.
-
-**Triggers — at least one must fire.**
-
-| Trigger | Condition |
-| --- | --- |
-| `first_report` | The feed holds nothing for this asset. |
-| `deviation` | The aggregate is `SEP40_DEVIATION_PCT` (default 0.5%) away from the **on-chain** price. |
-| `max_interval` | The on-chain price is older than `SEP40_MAX_INTERVAL_MS` (default 900000 = 15 min), even without moving. |
-
-`deviation` wins when both fire. The reference for deviation is
-`lastprice()` from the contract rather than a local variable, so two publisher
-instances (a restart racing itself, a canary) agree on what "moved" means.
-
-**Write vetoes — a trigger that fired still may not write.**
-
-| Veto | Condition |
-| --- | --- |
-| `tick_not_advanced` | The current feed tick is not newer than the last report — the contract would answer `NotNewer`, so Lens does not send a doomed transaction. |
-| `min_write_interval` | Fewer than `SEP40_MIN_WRITE_INTERVAL_MS` (default 60000) seconds since the last report. |
-
-Both record `suppressedBy`, so the audit row says which trigger was silenced and
-by what — the difference between "the market did not move" and "the market moved
-but we are rate-limited".
-
-`max_interval` is what stops a quiet market from leaving consumers reading a
-timestamp that only gets older; `min_write_interval` is the actual rate limit —
-it caps a fast market at one write per asset per interval, not one per sample.
-At the defaults, an hour of 30-second polling moves at least 0.5% every tick:
-**60 writes maximum, not 120**. The deviation threshold is measured against the
-value already on chain, so a slow drift publishes when it has accumulated, not
-on every step.
-
-`SEP40_MAX_AGE_SECONDS` (120) is deliberately stricter than the API's 300-second
-stale flag. An HTTP price can be "as good as we have it"; a price a contract
-settles against cannot.
-
----
-
-## 4. Deploying the feed
-
-### 4.1 Build (this part is reproducible here)
-
-```bash
-cd oracle/contract
-cargo build --release --target wasm32v1-none
-cargo test --lib          # 20 tests, no network needed
-```
-
-The release profile in `Cargo.toml` is the one Soroban wants: `opt-level = "z"`,
-`lto = true`, `panic = "abort"`. Output:
-`target/wasm32v1-none/release/lens_sep40_oracle.wasm`.
-
-`Cargo.lock` is committed. It pins `ed25519-dalek` to 2.2.0 on purpose:
-`soroban-env-host` 22.1.3 (which `soroban-sdk` 22.0.11 pins exactly) does not
-compile against the 3.0.0 release, and the resolution is what makes
-`cargo test --lib` work on a fresh clone.
-
-### 4.2 Deploy, initialize, hand over
-
-The `soroban` CLI is not part of this repository's CI, and its flag names and
-enum-argument JSON have moved between versions — check `soroban --version` and
-`<subcommand> --help` before pasting. The **sequence** is what matters, and each
-step is verifiable:
-
-```bash
-# 1. Deploy the WASM. The address it prints is your feed's SEP-40 address.
-soroban contract deploy --source "$ADMIN_ACCOUNT" --network testnet \
-  --wasm target/wasm32v1-none/release/lens_sep40_oracle.wasm
-
-# 2. Configure it once. base/decimals/resolution are immutable afterwards.
-soroban contract invoke --id "$FEED" --source "$ADMIN_ACCOUNT" --network testnet -- \
-  initialize --admin "$ADMIN_ACCOUNT" --base "<Asset::Other(\"USDC\") in your CLI's enum JSON>" \
-  --decimals 14 --resolution 60
-
-# 3. Point report at the hot publisher key (a different account from $ADMIN_ACCOUNT).
-soroban contract invoke --id "$FEED" --source "$ADMIN_ACCOUNT" --network testnet -- \
-  set_publisher --publisher "$PUBLISHER_ACCOUNT"
-
-# 4. Read the parameters back before letting Lens near it.
-soroban contract invoke --id "$FEED" --source "$ADMIN_ACCOUNT" --network testnet -- base
-soroban contract invoke --id "$FEED" --network testnet -- decimals
-soroban contract invoke --id "$FEED" --network testnet -- resolution
-```
-
-Recommended values, matching the contract's test suite and the scaling in
-`src/publish/sep40.ts`: `decimals = 14`, `resolution = 60`. Lens reads both from
-the contract at runtime and **fails closed** if the reads fail — there is no
-fallback scale. `base` should be the asset you want your consumers quoted in,
-and it must be one leg of every pair you intend to publish (§2).
-
-Upgrades keep the address:
-
-```bash
-soroban contract install --source "$ADMIN_ACCOUNT" --network testnet \
-  --wasm target/wasm32v1-none/release/lens_sep40_oracle.wasm      # prints the WASM hash
-soroban contract invoke --id "$FEED" --source "$ADMIN_ACCOUNT" --network testnet -- \
-  upgrade --new_wasm_hash "$WASM_HASH"
-```
-
-### 4.3 Run the publisher
-
-```bash
-# .env (never committed)
-ENABLED_NETWORKS=testnet
-SEP40_ENABLED_TESTNET=true
-SEP40_CONTRACT_ID_TESTNET=<the id step 4.2 printed>
-SEP40_PUBLISHER_SECRET_KEY_TESTNET=<S... of $PUBLISHER_ACCOUNT>
-```
-
-`src/index.ts` starts one publisher per enabled network the same way it starts
-venue ingesters — inside `restartIngester`, so a crash restarts that network's
-publisher after 10 s and cannot affect the other network or the other adapters.
-Startup is quiet and safe by default:
-
-- `SEP40_ENABLED_*=false` (the default) → the loop never starts.
-- Enabled but missing the contract id or the key → warning, publication stays off.
-- A malformed (`not even a valid C…` id) → `isUsableContractId` warns and
-  disables it, as it does for every other contract address in `src/config.ts`.
-
-Pair lists come from `WATCHED_PAIRS_TESTNET` / `WATCHED_PAIRS_MAINNET` for that
-network, not from the shared runtime registry, and every aggregate, venue and
-`price_points` query in the loop carries `network` in its WHERE clause. A
-publisher must not be able to quote testnet trades on a mainnet feed.
-
-No REST or GraphQL route is added: the point of SEP-40 is that a contract reads
-the feed on chain, and the existing `/price` already serves the off-chain
-consumer.
-
-### 4.4 Audit trail
-
-`oracle_publications` (Prisma model `OraclePublication`) records **writes**, not
-every blocked decision — at the default 30-second poll a blocked decision would
-be 2 880 rows a day per pair per network (5 760 on both, 17 280 for a three-pair
-list) all saying "nothing happened". Columns: `network`, `pairKey`,
-`quotedAsset`, `baseAsset`, `state` (`published` | `failed`), `trigger`,
-`price`, `scaledPrice` (the `i128` as text), `decimals`, `feedTimestamp`,
-`resolution`, `venues` (comma-joined names), `sourceCount`, `deviationPct`,
-`reason`, `txHash`, `errorMessage`, `createdAt`.
-
-A failed write is recorded the same way a success is and the loop continues with
-the next pair: the number Lens meant to publish, the venues behind it, and why it
-did not land is exactly what an operator needs at 3 a.m. A feed Lens cannot
-**read** is different — `FeedUnavailableError` aborts the cycle and the loop
-backs off (10 s, doubling, capped at 60 s), because "we could not check what is
-already on chain" means the deviation and monotonicity promises cannot be kept.
-
-`npm run db:migrate` (`prisma migrate dev`) creates the table; this repo
-has no migrations directory.
-
----
-
-## 5. Key handling
-
-Two accounts, and they are not interchangeable:
-
-| | Admin | Publisher |
-| --- | --- | --- |
-| Signs | `initialize`, `set_publisher`, `upgrade` | `report` — every publication |
-| Lives | Cold: hardware wallet, or an offline signer. Not in any server's env if you can avoid it. | Hot: `SEP40_PUBLISHER_SECRET_KEY_*` on the host running Lens |
-| Needs | Enough XLM for the rare admin transaction | XLM for one transaction per publication, per asset |
-| Leak damage | Attacker can upgrade the feed — catastrophic | Attacker can publish bad prices until you rotate — bad, recoverable |
-
-- **Funding.** The publisher pays every write's fee, so it needs XLM on the same
-  network as the feed. At the defaults the worst case is bounded and
-  computable: one write per asset per `SEP40_MIN_WRITE_INTERVAL_MS`, so
-  `pairs × (86400 / minWriteIntervalSeconds)` transactions per day — 1 440 per
-  asset per day at the 60-second floor, and typically far fewer, because a
-  deviation has to occur for a write to be attempted at all.
-- **Never committed.** `.env` is gitignored, `.env.example` carries the variable
-  names with empty values and comments only, and no secret key appears in source,
-  docs, tests, or changesets. The publisher only ever reads the key through
-  `Keypair.fromSecret()` inside `src/publish/onchain.ts`; it is not logged, not
-  returned, and not written to `oracle_publications`.
-- **Rotation.** Fund a new account, `set_publisher` to it (admin signs), update
-  `SEP40_PUBLISHER_SECRET_KEY_*`, restart. Until the new key is live the old one
-  still authorizes writes; after `set_publisher` the old one does not — the
-  contract compares the stored publisher address, it does not trust the
-  transaction's signer.
-- **Failing closed.** No key → no publication, with a log line saying so. A
-  partially configured publisher is worse than an absent one: it either burns
-  fees on the wrong feed or silently publishes nothing while looking healthy.
-- If you use one Lens process for both networks, use one publisher account per
-  network. A leaked testnet key should not be a mainnet problem.
-
----
-
-## 6. Reading the feed from a contract
-
-A consumer declares the same two types and calls the spec's names — nothing
-Lens-specific is required:
-
-```rust
-use soroban_sdk::{contract, contractimpl, symbol_short, Address, Env, IntoVal, Symbol};
-
-#[contracttype]
-#[derive(Clone)]
-pub enum Asset { Stellar(Address), Other(Symbol) }
-
-#[contracttype]
-#[derive(Clone)]
-pub struct PriceData { pub price: i128, pub timestamp: u64 }
-
-#[contract]
-pub struct Consumer;
-
-#[contractimpl]
-impl Consumer {
-    /// XLM per USDC, or nothing at all if the feed has no price or the caller's
-    /// staleness bar is not met.
-    pub fn spot(env: Env, feed: Address, max_age: u64) -> Option<i128> {
-        let asset = Asset::Other(symbol_short!("XLM"));
-        let data: PriceData = env
-            .invoke_contract::<Option<PriceData>>(
-                &feed,
-                &symbol_short!("lastprice"),
-                (asset,).into_val(&env),
-            )
-            .ok()??;
-        if env.ledger().timestamp() - data.timestamp > max_age {
-            return None;      // stale: refuse, rather than settle on an old tick
-        }
-        Some(data.price)      // still scaled by the feed's decimals()
-    }
-}
-```
-
-Check `None`, and check the age, before trusting a number: that is the whole
-consumer-side contract, and it is why `decimals`/`resolution` are readable
-entry points rather than documentation.
-
-## 7. Reading the feed from JS
-
-```ts
-import { contract as StellarContract, Networks, SorobanRpc } from '@stellar/stellar-sdk'
-
-const client = await StellarContract.Client.from({
-  contractId: process.env.SEP40_CONTRACT_ID_TESTNET!,
-  rpcUrl: 'https://soroban-testnet.stellar.org',
-  networkPassphrase: Networks.TESTNET,
-})
-
-// SEP-40's `Asset` is a `contracttype` enum with tuple variants, which the SDK
-// represents natively as { tag, values } — the form `assetToSpecArg` builds.
-const tx = await client.lastprice({ asset: { tag: 'Other', values: ['XLM'] } })
-if (!tx.result) throw new Error('the feed has no price for XLM yet')       // None
-const decimals = Number((await client.decimals()).result)                   // 14
-const price = Number(tx.result.price) / 10 ** decimals
-const ageSeconds = Math.floor(Date.now() / 1000) - Number(tx.result.timestamp)
-```
-
-Awaiting a dynamic `Client` method simulates the call and gives an
-`AssembledTransaction`; `.result` is the decoded return value. `None` from the
-contract arrives as `null`/`undefined` here, which is the check §6 also demands.
-
-`src/publish/sep40.ts` has the encoders both directions (`assetToScVal`,
-`assetFromSpecArg`, `scalePrice`, `unscalePrice`) if you need the XDR form, and
-`src/publish/onchain.ts` is the working `Client.from({...})` setup the publisher
-itself uses. Note the import path: this repo compiles with `module: commonjs`, so
-the `@stellar/stellar-sdk/contract` subpath does not resolve and the `contract`
-namespace comes from the package root.
-
-## 8. Tests
-
-```bash
-npm test -- src/__tests__/sep40Encoding.test.ts \
-            src/__tests__/sep40Trigger.test.ts \
-            src/__tests__/sep40Publisher.test.ts
-cd oracle/contract && cargo test --lib
-```
-
-This repo's tests are **vitest**, not jest. The three suites cover:
-
-- `sep40Encoding` — exact scaling (`0.29` at 14 decimals is the case that float
-  maths gets wrong), `i128` bounds, refusals, SAC-address derivation including
-  the mainnet USDC assertion and an imposter-issuer check, the `{tag, values}`
-  and `Vec[Symbol, value]` wire forms, venue list validation.
-- `sep40Trigger` — every guard outranking every trigger (a stale aggregate that
-  has also aged out must not publish), both write vetoes with `suppressedBy`,
-  and an hour-long simulated poll asserting the write count is rate-limited
-  rather than proportional to samples.
-- `sep40Publisher` — orientation and inversion, `base_not_in_pair`, provenance
-  audit rows, deviation measured against the on-chain value, a stale aggregate
-  proving **zero** `lastPrice`/`report` calls, failed writes recorded without
-  killing the cycle, and a bad issuer on one pair not silencing another.
-
-## 9. Known limits
-
-- One feed, one base. Pairs that do not contain the base are skipped with a
-  reason; quote more bases by deploying another feed.
-- Publication is off by default on every network and needs a funded publisher;
-  nothing in this feature runs unless an operator opts in.
-- `price(asset, timestamp)` answers from the retained 64 records. Older history
-  lives in Postgres and behind `/price/:a/:b/history`, not on chain.
-- The RPC layer (`ContractSep40Feed`) is not exercised against a deployed feed
-  by any test in this PR — there is no Lens feed contract to point at yet. What
-  is proven here is the policy around it (`sep40Publisher`), the encoding both
-  sides must agree on (`sep40Encoding`, `sep40Trigger`), and the contract itself
-  (`cargo test --lib`). Signing up to a real network is the remaining step, and
-  it needs a deployment first.
+# SEP-40 oracle publisher
+
+Lens has always been an oracle **consumer**: it reads Reflector's prices and
+compares them with its own. Issue #222 is the other direction — Lens as an
+oracle **publisher**, exposing a [SEP-40](https://github.com/StellarCommunity/seps/blob/main/SEP-0040.md)
+compatible price feed that any Soroban contract can read.
+
+Two pieces make up the feature:
+
+| Piece | Where | What it does |
+| --- | --- | --- |
+| The feed | `oracle/contract/` | A Soroban contract implementing SEP-40's `PriceFeedTrait`, plus one provider-side write (`report`). |
+| The publisher | `src/publish/` | The process that decides **when** a Lens aggregate is worth a transaction, and writes it. Runs once per enabled network, next to the ingest loops. |
+
+SEP-40 standardises the *read* side only ("the exact mechanism of data reporting
+mechanism utilized by an oracle is out of scope of this SEP"), so `report` is
+Lens's own design and every other entry point is exactly the shape the spec
+defines.
+
+---
+
+## 1. The contract
+
+`oracle/contract/src/lib.rs` — package `lens_sep40_oracle`.
+
+### 1.1 The SEP-40 read surface
+
+Declared names and signatures are the spec's, not adaptations:
+
+| Entry point | Signature | Lens's behaviour |
+| --- | --- | --- |
+| `base` | `() -> Asset` | The asset every price in the feed is denominated in. Set once at `initialize`. |
+| `assets` | `() -> Vec<Asset>` | Every asset that has ever been reported, in first-seen order. |
+| `decimals` | `() -> u32` | Scale of `PriceData.price`. Immutable. |
+| `resolution` | `() -> u32` | Tick period in seconds that timestamps are trimmed to. Immutable. |
+| `price` | `(Asset, u64) -> Option<PriceData>` | The newest record **at or before** the requested timestamp. |
+| `prices` | `(Asset, u32) -> Option<Vec<PriceData>>` | The last *n* records, newest first. |
+| `lastprice` | `(Asset) -> Option<PriceData>` | The current feed value. |
+| `last_report` | `(Asset) -> Option<Report>` | Lens-specific: provenance of the last write (see 1.4). |
+
+A deviation-triggered feed is deliberately non-uniform — there is no record at
+every tick — so `price(asset, timestamp)` answers with the value that was **in
+effect** at that time rather than looking for an exact match. That is the
+extrapolation SEP-40 asks an oracle to present, and it is why the feed can be
+consumed by contracts that assume a tick per resolution.
+
+### 1.2 Price encoding
+
+`PriceData.price` is an `i128` scaled by `decimals()`:
+
+```
+real_price = PriceData.price / 10^decimals()
+```
+
+`PriceData.timestamp` is unix **seconds**, and the contract enforces SEP-40's
+trimming rule on every write:
+
+```
+timestamp == floor(unix_now() / resolution()) * resolution()
+```
+
+A write whose timestamp is not a whole number of ticks is rejected
+(`TimestampNotAligned`), so a consumer can treat trimming as a guarantee instead
+of a convention. Lens trims on the way out (`trimTimestamp` in
+`src/publish/sep40.ts`) and the contract re-checks.
+
+Scaling is done through a decimal **string**, not a float multiply, because
+`0.29 * 1e14` is `28999999999999.996` — `BigInt()` of that throws and
+`Math.round()` of that puts `28999999999999` on chain. One decimal digit off is
+a price that is wrong by a factor of ten, so `scalePrice` refuses non-integer
+results, exponential notation, non-positive prices and values beyond `i128`.
+
+### 1.3 `None`, not an error
+
+SEP-40: "oracles should delegate error handling logic directly to consumer
+contracts". So the read side returns `None` — never a revert — for an asset the
+feed has never quoted, a timestamp before the first report, a `records` count of
+zero, and an empty history. A consumer that wants to distinguish "no data" from
+"bad request" has to ask for `last_report` or call `assets()`; a consumer that
+just wants to not settle on missing data checks for `None`.
+
+### 1.4 Provenance, beyond SEP-40
+
+SEP-40's `PriceData` has no room for "where did this come from", and Lens
+refuses to publish a number it cannot source. Every `report` therefore carries
+the venue names behind it:
+
+```rust
+pub struct Report {
+    pub price: i128,
+    pub timestamp: u64,       // SEP-40 feed timestamp
+    pub reported_at: u64,     // ledger close time of the write
+    pub reported_ledger: u32, // ledger the write landed in
+    pub source_count: u32,    // always venues.len()
+    pub venues: Vec<Symbol>,  // 'SDEX', 'AMM', 'aquarius_amm', 'soroswap_amm', …
+}
+```
+
+`source_count` is **derived** from the venue list rather than passed in, so the
+contract cannot store a price claiming more sources than it can name. An empty
+venue list is rejected (`NoVenues`), as is a list longer than `MAX_VENUES` (16).
+Venues are never blended: the aggregate `price` is a route-aware best quote and
+the list says which markets produced it, exactly as `/price/:a/:b` reports
+`bestRoute` and `sources`.
+
+`reported_at` and `reported_ledger` are what let a consumer apply the same
+staleness bar the HTTP API does: `lastprice.timestamp` says when the *market*
+tick happened, `last_report.reported_at` says when the feed *learned* it.
+
+### 1.5 Errors
+
+| Code | Name | Raised when |
+| --- | --- | --- |
+| 1 | `AlreadyInitialized` | `initialize` is called a second time. |
+| 2 | `NonPositivePrice` | `price <= 0`. |
+| 3 | `TimestampNotAligned` | `timestamp % resolution != 0`. |
+| 4 | `NotNewer` | `timestamp` is not strictly newer than the asset's last record. |
+| 5 | `TimestampInFuture` | `timestamp > env.ledger().timestamp()`. |
+| 6 | `NoVenues` | Empty venue list. |
+| 7 | `TooManyVenues` | More than `MAX_VENUES` names. |
+| 8 | `InvalidConfig` | `decimals == 0` or `resolution == 0` at `initialize`. |
+
+`NotNewer` and `TimestampInFuture` are what make a retried publish harmless: a
+replay of a tick that already landed is refused, and a publisher with a clock
+ahead of the ledger cannot hand consumers a price that never ages.
+
+### 1.6 Admin surface
+
+- `initialize(admin, base, decimals, resolution)` — one-shot, admin-authenticated.
+- `set_publisher(publisher)` — admin-authenticated; points `report` at the hot key.
+- `upgrade(new_wasm_hash)` — admin-authenticated; swaps the WASM **without
+  changing the contract address**, which SEP-40 requires ("smart contract
+  consumers should only be expected to change their price feed aggregator address
+  if they would like to change oracle providers").
+
+`report` authorizes exactly one address: the publisher when one is set, the
+admin otherwise. Tests assert both halves of that — that a write carrying no
+publisher authorization does not land, and that the address the feed demands is
+the publisher and not the transaction's signer.
+
+### 1.7 Storage
+
+Per asset: `Last` (one `PriceData`), `LastReport` (one `Report`) and `History`
+(newest-first, trimmed to `MAX_HISTORY = 64` records). The asset registry is one
+instance entry. Persistent entries extend their TTL on read and write
+(`TTL_THRESHOLD = 5_000`, `TTL_BUMP = 40_000` ledgers), and instance storage is
+extended at `initialize`, so an idle feed does not expire out from under its
+consumers.
+
+---
+
+## 2. How a Lens pair becomes a feed value
+
+Lens stores a pair as **`price` = units of assetB per assetA**. SEP-40 quotes
+every asset against one **base**. `orientAgainstBase` in
+`src/publish/publisher.ts` reconciles the two from the base the *deployed
+contract* reports — never from an env var, because a mis-declared scale produces
+a price that is wrong by orders of magnitude and still reads fine:
+
+| Feed `base` | Quoted asset | Price published |
+| --- | --- | --- |
+| equals `assetB` | `assetA` | the stored number, as-is |
+| equals `assetA` | `assetB` | `1 / stored` (inverted) |
+| neither | — | pair skipped, reason recorded |
+
+Worked example, the default pair in `.env.example`: `XLM:native / USDC:GBBD47IF6LWK7P7MDEVSCWR7DPUWV3NY3DTQEVFL4NAT4AQH3ZLLFLA5`
+stores `price = USDC per XLM`. With `base = Other("USDC")`, `decimals = 14`, the
+feed quotes `Asset::Other("XLM")` directly — `0.025` becomes `250000000000000`.
+The same feed pointed at `base = Other("XLM")` would quote the USDC leg and
+publish `1 / 0.025 = 40` as `400000000000000000000`.
+
+A pair whose legs are neither of them is **not** published. Putting a ratio under
+the wrong asset label is worse than an empty feed, so the cycle records the
+reason (`base_not_in_pair`) and moves on.
+
+Asset identity follows SEP-40: an anchored asset is identified by the address of
+its **Stellar Asset Contract**, derived with
+`new Asset(code, issuer).contractId(passphrase)` — issuer-qualified by
+construction, so two tokens called USDC are two different assets. Native XLM has
+no asset contract and uses the spec's `Other(Symbol)` form. Contract addresses
+are derived from the issuer in `WATCHED_PAIRS_*`, never typed by hand. As one
+reference point, mainnet USDC (`GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN`)
+derives to `CCW67TSZV3SSS2HXMBQ5JFGCKJNXKZM7UQUWUZPUTHXSTZLEO7SJMI75`; the test
+suite asserts that derivation so a typo in the issuer cannot pass silently.
+**This document deliberately contains no Lens feed contract id** — it is created
+when the operator deploys `oracle/contract/` (§4), and a placeholder in the docs
+is how five deployments end up pointing at five different guesses.
+
+---
+
+## 3. When Lens writes
+
+The policy is `src/publish/trigger.ts`, a pure function over
+(aggregate, what is already on chain, thresholds, clock). It exists because a
+tick is not an event: Lens polls every few seconds, and a publisher that wrote
+per sample would be a transaction spam bot that also publishes the noise between
+trades.
+
+Order matters, and it is what makes the acceptance criteria checkable:
+
+**Guards — evaluated first, before any chain read.**
+
+| Guard | Condition |
+| --- | --- |
+| `no_venue` | No venue name behind the number. "A price you cannot source is worse than no price." |
+| `invalid_price` | Zero, negative or non-finite. |
+| `no_observation` | No trade has ever been recorded for this pair **on this network**. |
+| `stale_aggregate` | The aggregator's own `stale` flag is set — the same signal `/price` reports, so the feed can never carry a price the API calls stale. |
+| `aggregate_too_old` | `lastTradeAgeSeconds > SEP40_MAX_AGE_SECONDS` (default 120). |
+
+`evaluateGuards` runs **before** `lastprice` is read. A stale aggregate needs no
+comparison to decide anything — it is simply not publishable — so a blocked tick
+provably touches no RPC and spends no fee. That is the "a stale aggregate is
+never published" criterion as a code path, not as a promise.
+
+**Triggers — at least one must fire.**
+
+| Trigger | Condition |
+| --- | --- |
+| `first_report` | The feed holds nothing for this asset. |
+| `deviation` | The aggregate is `SEP40_DEVIATION_PCT` (default 0.5%) away from the **on-chain** price. |
+| `max_interval` | The on-chain price is older than `SEP40_MAX_INTERVAL_MS` (default 900000 = 15 min), even without moving. |
+
+`deviation` wins when both fire. The reference for deviation is
+`lastprice()` from the contract rather than a local variable, so two publisher
+instances (a restart racing itself, a canary) agree on what "moved" means.
+
+**Write vetoes — a trigger that fired still may not write.**
+
+| Veto | Condition |
+| --- | --- |
+| `tick_not_advanced` | The current feed tick is not newer than the last report — the contract would answer `NotNewer`, so Lens does not send a doomed transaction. |
+| `min_write_interval` | Fewer than `SEP40_MIN_WRITE_INTERVAL_MS` (default 60000) seconds since the last report. |
+
+Both record `suppressedBy`, so the audit row says which trigger was silenced and
+by what — the difference between "the market did not move" and "the market moved
+but we are rate-limited".
+
+`max_interval` is what stops a quiet market from leaving consumers reading a
+timestamp that only gets older; `min_write_interval` is the actual rate limit —
+it caps a fast market at one write per asset per interval, not one per sample.
+At the defaults, an hour of 30-second polling moves at least 0.5% every tick:
+**60 writes maximum, not 120**. The deviation threshold is measured against the
+value already on chain, so a slow drift publishes when it has accumulated, not
+on every step.
+
+`SEP40_MAX_AGE_SECONDS` (120) is deliberately stricter than the API's 300-second
+stale flag. An HTTP price can be "as good as we have it"; a price a contract
+settles against cannot.
+
+---
+
+## 4. Deploying the feed
+
+### 4.1 Build (this part is reproducible here)
+
+```bash
+cd oracle/contract
+cargo build --release --target wasm32v1-none
+cargo test --lib          # 20 tests, no network needed
+```
+
+The release profile in `Cargo.toml` is the one Soroban wants: `opt-level = "z"`,
+`lto = true`, `panic = "abort"`. Output:
+`target/wasm32v1-none/release/lens_sep40_oracle.wasm`.
+
+`Cargo.lock` is committed. It pins `ed25519-dalek` to 2.2.0 on purpose:
+`soroban-env-host` 22.1.3 (which `soroban-sdk` 22.0.11 pins exactly) does not
+compile against the 3.0.0 release, and the resolution is what makes
+`cargo test --lib` work on a fresh clone.
+
+### 4.2 Deploy, initialize, hand over
+
+The `soroban` CLI is not part of this repository's CI, and its flag names and
+enum-argument JSON have moved between versions — check `soroban --version` and
+`<subcommand> --help` before pasting. The **sequence** is what matters, and each
+step is verifiable:
+
+```bash
+# 1. Deploy the WASM. The address it prints is your feed's SEP-40 address.
+soroban contract deploy --source "$ADMIN_ACCOUNT" --network testnet \
+  --wasm target/wasm32v1-none/release/lens_sep40_oracle.wasm
+
+# 2. Configure it once. base/decimals/resolution are immutable afterwards.
+soroban contract invoke --id "$FEED" --source "$ADMIN_ACCOUNT" --network testnet -- \
+  initialize --admin "$ADMIN_ACCOUNT" --base "<Asset::Other(\"USDC\") in your CLI's enum JSON>" \
+  --decimals 14 --resolution 60
+
+# 3. Point report at the hot publisher key (a different account from $ADMIN_ACCOUNT).
+soroban contract invoke --id "$FEED" --source "$ADMIN_ACCOUNT" --network testnet -- \
+  set_publisher --publisher "$PUBLISHER_ACCOUNT"
+
+# 4. Read the parameters back before letting Lens near it.
+soroban contract invoke --id "$FEED" --source "$ADMIN_ACCOUNT" --network testnet -- base
+soroban contract invoke --id "$FEED" --network testnet -- decimals
+soroban contract invoke --id "$FEED" --network testnet -- resolution
+```
+
+Recommended values, matching the contract's test suite and the scaling in
+`src/publish/sep40.ts`: `decimals = 14`, `resolution = 60`. Lens reads both from
+the contract at runtime and **fails closed** if the reads fail — there is no
+fallback scale. `base` should be the asset you want your consumers quoted in,
+and it must be one leg of every pair you intend to publish (§2).
+
+Upgrades keep the address:
+
+```bash
+soroban contract install --source "$ADMIN_ACCOUNT" --network testnet \
+  --wasm target/wasm32v1-none/release/lens_sep40_oracle.wasm      # prints the WASM hash
+soroban contract invoke --id "$FEED" --source "$ADMIN_ACCOUNT" --network testnet -- \
+  upgrade --new_wasm_hash "$WASM_HASH"
+```
+
+### 4.3 Run the publisher
+
+```bash
+# .env (never committed)
+ENABLED_NETWORKS=testnet
+SEP40_ENABLED_TESTNET=true
+SEP40_CONTRACT_ID_TESTNET=<the id step 4.2 printed>
+SEP40_PUBLISHER_SECRET_KEY_TESTNET=<S... of $PUBLISHER_ACCOUNT>
+```
+
+`src/index.ts` starts one publisher per enabled network the same way it starts
+venue ingesters — inside `restartIngester`, so a crash restarts that network's
+publisher after 10 s and cannot affect the other network or the other adapters.
+Startup is quiet and safe by default:
+
+- `SEP40_ENABLED_*=false` (the default) → the loop never starts.
+- Enabled but missing the contract id or the key → warning, publication stays off.
+- A malformed (`not even a valid C…` id) → `isUsableContractId` warns and
+  disables it, as it does for every other contract address in `src/config.ts`.
+
+Pair lists come from `WATCHED_PAIRS_TESTNET` / `WATCHED_PAIRS_MAINNET` for that
+network, not from the shared runtime registry, and every aggregate, venue and
+`price_points` query in the loop carries `network` in its WHERE clause. A
+publisher must not be able to quote testnet trades on a mainnet feed.
+
+No REST or GraphQL route is added: the point of SEP-40 is that a contract reads
+the feed on chain, and the existing `/price` already serves the off-chain
+consumer.
+
+### 4.4 Audit trail
+
+`oracle_publications` (Prisma model `OraclePublication`) records **writes**, not
+every blocked decision — at the default 30-second poll a blocked decision would
+be 2 880 rows a day per pair per network (5 760 on both, 17 280 for a three-pair
+list) all saying "nothing happened". Columns: `network`, `pairKey`,
+`quotedAsset`, `baseAsset`, `state` (`published` | `failed`), `trigger`,
+`price`, `scaledPrice` (the `i128` as text), `decimals`, `feedTimestamp`,
+`resolution`, `venues` (comma-joined names), `sourceCount`, `deviationPct`,
+`reason`, `txHash`, `errorMessage`, `createdAt`.
+
+A failed write is recorded the same way a success is and the loop continues with
+the next pair: the number Lens meant to publish, the venues behind it, and why it
+did not land is exactly what an operator needs at 3 a.m. A feed Lens cannot
+**read** is different — `FeedUnavailableError` aborts the cycle and the loop
+backs off (10 s, doubling, capped at 60 s), because "we could not check what is
+already on chain" means the deviation and monotonicity promises cannot be kept.
+
+`npm run db:migrate` (`prisma migrate dev`) creates the table; this repo
+has no migrations directory.
+
+---
+
+## 5. Key handling
+
+Two accounts, and they are not interchangeable:
+
+| | Admin | Publisher |
+| --- | --- | --- |
+| Signs | `initialize`, `set_publisher`, `upgrade` | `report` — every publication |
+| Lives | Cold: hardware wallet, or an offline signer. Not in any server's env if you can avoid it. | Hot: `SEP40_PUBLISHER_SECRET_KEY_*` on the host running Lens |
+| Needs | Enough XLM for the rare admin transaction | XLM for one transaction per publication, per asset |
+| Leak damage | Attacker can upgrade the feed — catastrophic | Attacker can publish bad prices until you rotate — bad, recoverable |
+
+- **Funding.** The publisher pays every write's fee, so it needs XLM on the same
+  network as the feed. At the defaults the worst case is bounded and
+  computable: one write per asset per `SEP40_MIN_WRITE_INTERVAL_MS`, so
+  `pairs × (86400 / minWriteIntervalSeconds)` transactions per day — 1 440 per
+  asset per day at the 60-second floor, and typically far fewer, because a
+  deviation has to occur for a write to be attempted at all.
+- **Never committed.** `.env` is gitignored, `.env.example` carries the variable
+  names with empty values and comments only, and no secret key appears in source,
+  docs, tests, or changesets. The publisher only ever reads the key through
+  `Keypair.fromSecret()` inside `src/publish/onchain.ts`; it is not logged, not
+  returned, and not written to `oracle_publications`.
+- **Rotation.** Fund a new account, `set_publisher` to it (admin signs), update
+  `SEP40_PUBLISHER_SECRET_KEY_*`, restart. Until the new key is live the old one
+  still authorizes writes; after `set_publisher` the old one does not — the
+  contract compares the stored publisher address, it does not trust the
+  transaction's signer.
+- **Failing closed.** No key → no publication, with a log line saying so. A
+  partially configured publisher is worse than an absent one: it either burns
+  fees on the wrong feed or silently publishes nothing while looking healthy.
+- If you use one Lens process for both networks, use one publisher account per
+  network. A leaked testnet key should not be a mainnet problem.
+
+---
+
+## 6. Reading the feed from a contract
+
+A consumer declares the same two types and calls the spec's names — nothing
+Lens-specific is required:
+
+```rust
+use soroban_sdk::{contract, contractimpl, symbol_short, Address, Env, IntoVal, Symbol};
+
+#[contracttype]
+#[derive(Clone)]
+pub enum Asset { Stellar(Address), Other(Symbol) }
+
+#[contracttype]
+#[derive(Clone)]
+pub struct PriceData { pub price: i128, pub timestamp: u64 }
+
+#[contract]
+pub struct Consumer;
+
+#[contractimpl]
+impl Consumer {
+    /// XLM per USDC, or nothing at all if the feed has no price or the caller's
+    /// staleness bar is not met.
+    pub fn spot(env: Env, feed: Address, max_age: u64) -> Option<i128> {
+        let asset = Asset::Other(symbol_short!("XLM"));
+        let data: PriceData = env
+            .invoke_contract::<Option<PriceData>>(
+                &feed,
+                &symbol_short!("lastprice"),

+        if env.ledger().timestamp() - data.timestamp > max_age {
+            return None;      // stale: refuse, rather than settle on an old tick
+        }
+        Some(data.price)      // still scaled by the feed's decimals()
+    }
+}
+```
+
+Check `None`, and check the age, before trusting a number: that is the whole
+consumer-side contract, and it is why `decimals`/`resolution` are readable
+entry points rather than documentation.
+
+## 7. Reading the feed from JS
+
+```ts
+import { contract as StellarContract, Networks, SorobanRpc } from '@stellar/stellar-sdk'
+
+const client = await StellarContract.Client.from({
+  contractId: process.env.SEP40_CONTRACT_ID_TESTNET!,
+  rpcUrl: 'https://soroban-testnet.stellar.org',
+  networkPassphrase: Networks.TESTNET,
+})
+
+// SEP-40's `Asset` is a `contracttype` enum with tuple variants, which the SDK
+// represents natively as { tag, values } — the form `assetToSpecArg` builds.
+const tx = await client.lastprice({ asset: { tag: 'Other', values: ['XLM'] } })
+if (!tx.result) throw new Error('the feed has no price for XLM yet')       // None
+const decimals = Number((await client.decimals()).result)                   // 14
+const price = Number(tx.result.price) / 10 ** decimals
+const ageSeconds = Math.floor(Date.now() / 1000) - Number(tx.result.timestamp)
+```
+
+Awaiting a dynamic `Client` method simulates the call and gives an
+`AssembledTransaction`; `.result` is the decoded return value. `None` from the
+contract arrives as `null`/`undefined` here, which is the check §6 also demands.
+
+`src/publish/sep40.ts` has the encoders both directions (`assetToScVal`,
+`assetFromSpecArg`, `scalePrice`, `unscalePrice`) if you need the XDR form, and
+`src/publish/onchain.ts` is the working `Client.from({...})` setup the publisher
+itself uses. Note the import path: this repo compiles with `module: commonjs`, so
+the `@stellar/stellar-sdk/contract` subpath does not resolve and the `contract`
+namespace comes from the package root.
+
+## 8. Tests
+
+```bash
+npm test -- src/__tests__/sep40Encoding.test.ts \
+            src/__tests__/sep40Trigger.test.ts \
+            src/__tests__/sep40Publisher.test.ts
+cd oracle/contract && cargo test --lib
+```
+
+This repo's tests are **vitest**, not jest. The three suites cover:
+
+- `sep40Encoding` — exact scaling (`0.29` at 14 decimals is the case that float
+  maths gets wrong), `i128` bounds, refusals, SAC-address derivation including
+  the mainnet USDC assertion and an imposter-issuer check, the `{tag, values}`
+  and `Vec[Symbol, value]` wire forms, venue list validation.
+- `sep40Trigger` — every guard outranking every trigger (a stale aggregate that
+  has also aged out must not publish), both write vetoes with `suppressedBy`,
+  and an hour-long simulated poll asserting the write count is rate-limited
+  rather than proportional to samples.
+- `sep40Publisher` — orientation and inversion, `base_not_in_pair`, provenance
+  audit rows, deviation measured against the on-chain value, a stale aggregate
+  proving **zero** `lastPrice`/`report` calls, failed writes recorded without
+  killing the cycle, and a bad issuer on one pair not silencing another.
+
+## 9. Known limits
+
+- One feed, one base. Pairs that do not contain the base are skipped with a
+  reason; quote more bases by deploying another feed.
+- Publication is off by default on every network and needs a funded publisher;
+  nothing in this feature runs unless an operator opts in.
+- `price(asset, timestamp)` answers from the retained 64 records. Older history
+  lives in Postgres and behind `/price/:a/:b/history`, not on chain.
+- The RPC layer (`ContractSep40Feed`) is not exercised against a deployed feed
+  by any test in this PR — there is no Lens feed contract to point at yet. What
+  is proven here is the policy around it (`sep40Publisher`), the encoding both
+  sides must agree on (`sep40Encoding`, `sep40Trigger`), and the contract itself
+  (`cargo test --lib`). Signing up to a real network is the remaining step, and
+  it needs a deployment first.

-# WebSocket backpressure
-
-Lens streams live prices over `/ws`. One property of that stream decides how the
-server has to behave: **`send()` does not block and does not throw when a peer
-is slow.** It queues. A client on a bad mobile connection, or one whose process
-has been suspended and whose TCP window has filled, accumulates payloads in its
-socket's internal buffer. Nothing inspected `bufferedAmount`, so that buffer had
-no upper bound, and the message was counted as sent the moment it was queued.
-
-With a price feed pushing updates continuously, one stuck subscriber was enough
-to grow the process until it was OOM-killed — taking every other subscriber, and
-every HTTP client, with it.
-
-The fix is a policy over the socket's `bufferedAmount`, applied per client. It
-lives in [`src/ws/fanout.ts`](../src/ws/fanout.ts) (`FanOutManager.deliver`);
-the limits and their defaults are in
-[`src/ws/backpressure.ts`](../src/ws/backpressure.ts).
-
-## The policy
-
-Checked per client, per update, in this order:
-
-| Tier | Condition | Action |
-|---|---|---|
-| 1. Evict (dead peer) | `bufferedAmount >= WS_MAX_BUFFERED_BYTES` | Close with **1013**, unregister, count `ws_clients_dropped_total`. |
-| 2. Evict (stuck peer) | congested continuously for `WS_MAX_CONGESTED_MS` | Close with **1013**, unregister, count `ws_clients_dropped_total`. |
-| 3. Coalesce | `bufferedAmount >= WS_SLOW_CLIENT_BUFFER_BYTES`, or inside the coalescing window | Keep only the newest update; count every superseded one in `ws_messages_dropped_total`. |
-| 4. Send | otherwise | Send, and count `ws_messages_sent_total` when the socket reports the write completed. |
-
-**Why 1013.** RFC 6455 §7.4.1 reserves 1013 for "Try Again Later": the server is
-refusing to keep serving this client right now. The condition here is the
-client's rather than the server's, but the meaning to a client is the one it
-already handles for a throttled feed — back off and reconnect, do not treat the
-close as fatal. The close reason is one of `buffer limit exceeded` or
-`congested too long`, kept short because RFC 6455 caps a close reason at 123
-bytes.
-
-**Why coalescing is the primary tier.** For a price feed, an intermediate tick
-that arrives late is worthless: the newest tick has already superseded it, so
-truncating the backlog costs the client nothing it could still use — and costs
-the server one payload per client instead of one per tick. Tier 3 also covers
-the ordinary coalescing window (`WS_COALESCE_INTERVAL_MS`, 10 updates/sec by
-default), which existed before and is the same behaviour for the same reason.
-
-**Why evict at all.** Coalescing bounds the memory a slow client costs. It does
-not bound the *time*: a client that has stopped reading entirely would sit
-there forever, holding a slot, its buffered bytes and a `ws_clients_total`
-series, with no metric saying why. Tier 1 catches a peer wedged past the hard
-limit; tier 2 catches one wedged below it.
-
-**Why the soft limit is clamped.** `WS_SLOW_CLIENT_BUFFER_BYTES` is forced below
-`WS_MAX_BUFFERED_BYTES` (at half of it). Set at or above, every client past the
-soft limit would be disconnected on its first update over it and tier 3 — the
-one that keeps a merely-slow client connected — would never run.
-
-## Defaults
-
-| Variable | Default | Meaning |
-|---|---|---|
-| `WS_COALESCE_INTERVAL_MS` | `100` | Max updates per second per client. `0` disables the window. |
-| `WS_SLOW_CLIENT_BUFFER_BYTES` | `262144` (256 KiB) | Queued bytes above which updates are coalesced. Over a thousand ticks of backlog. |
-| `WS_MAX_BUFFERED_BYTES` | `1048576` (1 MiB) | Queued bytes above which the client is closed. |
-| `WS_MAX_CONGESTED_MS` | `30000` | How long a client may stay congested. `0` keeps them indefinitely. |
-| `WS_BUFFER_SWEEP_INTERVAL_MS` | `5000` | How often `ws_buffered_bytes` is refreshed. |
-
-## Counting, honestly
-
-- `ws_messages_sent_total` increments **when the socket reports the write
-  completed**, not when `send()` was called. `send()` returns once the payload is
-  queued, so counting there reported messages as delivered when they were only in
-  a buffer — including for a client that had stopped reading and would never see
-  them.
-- `ws_messages_dropped_total` counts updates discarded because a newer one
-  superseded them, plus the retained update dropped when a client is evicted.
-- `ws_clients_dropped_total` counts evicted clients.
-- `ws_buffered_bytes` is the aggregate of every client's queued bytes, sampled on
-  a timer. Aggregate only: one series per client would be unbounded cardinality
-  driven by caller-supplied subscription strings.
-
-All four keep the existing bounded `pair` label: pair-specific subscriptions are
-recorded as `other`, `*` is the aggregate. See
-[`http-metrics.md`](http-metrics.md).

-# x402 conformance: baseline against the public facilitator
-
-A record of what the **public `x402.org` facilitator actually does** on
-`stellar:testnet`, established by pointing a canonical client at it and feeding
-it deliberately bad input. This is the baseline Lens's own facilitator (#124,
-#125, #126) is measured against — without it, "conformant" means nothing more
-than our own reading of the spec, which is exactly the drift the RFP screens
-for.
-
-Everything below was executed against live testnet. Nothing here is inferred.
-
-## What was run
-
-| | |
-| --- | --- |
-| Facilitator | `https://x402.org/facilitator` (no API key required) |
-| Network | `stellar:testnet` |
-| Scheme | `exact` |
-| Spec | [`scheme_exact_stellar.md`](https://github.com/x402-foundation/x402/blob/main/specs/schemes/exact/scheme_exact_stellar.md) @ `c4d2de655d1dfca63f54100e32de019b26aaacdd` (2026-07-17, "fix stellar tx fee (#2852)") |
-| Client | `@stellar/stellar-sdk` **16.2.0**, unmodified — stock `simulateTransaction`, `authorizeEntry`, `assembleTransaction`. No patched SDK, no local shims. |
-| Date | 2026-08-31 |
-
-**Scope note, stated plainly:** this is *not* a run of the x402 repository's own
-e2e suite. That suite is not currently runnable against an arbitrary facilitator
-without vendoring its harness. What was done instead is the check the RFP
-actually describes — building a canonical client straight from the published
-spec with the stock SDK, and completing a payment end to end. Where that is a
-weaker signal than running their suite, it is a stronger one than reading the
-spec, and the settled transaction hash below is verifiable by anyone.
-
-## Headline result: a payment settled end to end
-
-A real `exact` payment on `stellar:testnet`, verified and settled by the public
-facilitator, with a client that had never been pointed at it before.
-
-| | |
-| --- | --- |
-| Transaction | [`988dca9e7a204a59534912ff502fd81056f571e35f2cb87812bdfdc3292d9f17`](https://stellar.expert/explorer/testnet/tx/988dca9e7a204a59534912ff502fd81056f571e35f2cb87812bdfdc3292d9f17) |
-| Ledger | 4425809 |
-| Result | `successful: true` |
-| Payer | `GBJ72MK5OQ3N2X2DZGUCBHFZM62UA4W3B7ZKKY53NREMYWBSMLQMBWND` |
-| Recipient | `GD7FSGAFENIMMKU5QZZR76O53NNSL7QQ6NFGROXKA26JX4FYXNN363OF` — balance went to exactly `1.0000000` |
-| Asset | `CDBH3ITPRJRLINW5TKQCEFARO6UCUZZBGPBVT6QGZJ7WQQ2VOTYND2OM` (a SAC deployed for this test) |
-
-**Fee sponsorship is real, not just advertised.** The submitted transaction's
-source account is `GC6CSXBV4C6RL3HEDTW57KXYXSSXKAWKGYDEOSATXM3XNKXSR2VRYN3K` —
-the facilitator's own account, not the payer's — and the 23,059 stroop fee was
-charged to it. `extra.areFeesSponsored: true` is therefore backed by observed
-behaviour. (23,059 stroops also sits comfortably under the spec's 50,000-stroop
-default ceiling.)
-
-## `/supported`, captured verbatim
-
-`GET https://x402.org/facilitator/supported` → `200`. The Stellar entry:
-
-```json
-{ "x402Version": 2, "scheme": "exact", "network": "stellar:testnet", "extra": { "areFeesSponsored": true } }
-```
-
-This matches the RFP's stated contract exactly: the Stellar `extra` block is
-present, `areFeesSponsored` is `true`, and the identifier is CAIP-2.
-
-All 11 advertised kinds:
-
-| x402Version | scheme | network | extra |
-| --- | --- | --- | --- |
-| 2 | `exact` | `eip155:84532` | — |
-| 2 | `upto` | `eip155:84532` | `facilitatorAddress` |
-| 2 | `batch-settlement` | `eip155:84532` | — |
-| 2 | `exact` | `solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1` | `feePayer`, `features.smartWalletSupported` |
-| 2 | `exact` | `algorand:SGO1GKSzyE7IEPItTxCByw9x8FmnrCDe` | `feePayer` |
-| 2 | `exact` | `aptos:2` | `feePayer` |
-| 2 | `exact` | **`stellar:testnet`** | `areFeesSponsored: true` |
-| 2 | `exact` | `hedera:testnet` | `feePayer` |
-| 2 | `exact` | `xrpl:1` | `areFeesSponsored: false` |
-| 1 | `exact` | `base-sepolia` | — |
-| 1 | `exact` | `solana-devnet` | — |
-
-Two things to note. **Stellar mainnet is not served** — `stellar:testnet` is the
-only Stellar entry, so nothing about mainnet behaviour can be inferred from this
-facilitator. And **CAIP-2 holds only for `x402Version: 2`**: the two v1 entries
-use the legacy non-CAIP-2 names `base-sepolia` and `solana-devnet`. A client that
-reads `/supported` and assumes CAIP-2 throughout will mis-parse those two rows.
-
-## Rejection reasons: does every rejection carry one?
-
-The RFP's requirement is that every rejection carries a non-null `reason`. Fed
-deliberately bad input, the answer is **yes for `invalidReason`, and no for
-anything human-readable**. Results, all live:
-
-### Structural checks against a real signed payload
-
-Each of these starts from the *same* valid payload that settled above, with one
-field changed — so a specific reason is genuinely available to the facilitator.
-
-| Input | HTTP | `invalidReason` | Verdict |
-| --- | --- | --- | --- |
-| Control, unmodified | 200 | — (`isValid: true`) | ✅ |
-| `requirements.payTo` ≠ transaction's `to` | 200 | `invalid_exact_stellar_payload_wrong_recipient` | ✅ specific |
-| `requirements.asset` ≠ transaction's contract | 200 | `invalid_exact_stellar_payload_wrong_asset` | ✅ specific |
-| `requirements.amount` ≠ transaction's amount | 200 | `invalid_exact_stellar_payload_wrong_amount` | ✅ specific |
-| Auth expiration `+100` ledgers (cap is `+12`) | 200 | `invalid_exact_stellar_signature_expiration_too_far` | ✅ specific |
-| Auth expiration `+1000` | 200 | `invalid_exact_stellar_signature_expiration_too_far` | ✅ specific |
-| Auth expiration `+100000` | 200 | `invalid_exact_stellar_signature_expiration_too_far` | ✅ specific |
-| **Auth expiration 50 ledgers in the past** | 200 | `invalid_exact_stellar_payload_simulation_failed` | ⚠️ generic |
-| **Replay of the already-settled payload** | 200 | `invalid_exact_stellar_payload_simulation_failed` | ⚠️ generic |
-| Source-account auth credential (not address) | 200 | `invalid_exact_stellar_payload_unsupported_credential_type` | ✅ specific |
-
-Spec §3's expiration ceiling is enforced properly, with its own named reason. The
-opposite direction is not: an entry that has **already expired** is caught only
-when simulation fails, and reports the same generic reason as a replay, an
-insufficient balance, or any other state problem.
-
-### Malformed payloads
-

-| **`network: stellar:pubnet` (not advertised)** | **500** | `unexpected_error` |
-| **`scheme: upto` on Stellar (not advertised)** | **500** | `unexpected_error` |
-
-### `payload: { transaction }` accepted verbatim?
-
-**Yes.** The spec's `payload` shape was sent exactly as published — a single
-`transaction` key holding base64 XDR — inside the spec's full `PaymentPayload`
-envelope with `x402Version`, `resource` and `accepted`. It was accepted with no
-adjustment on the first attempt.
-
-## Divergences found
-
-### 1. Unsupported network or scheme returns HTTP 500, not a rejection
-
-The single most consequential finding. Asking for something the facilitator does
-not serve — `stellar:pubnet`, or `upto` on Stellar — produces:
-
-```
-HTTP 500
-{"isValid":false,"invalidReason":"unexpected_error",
- "invalidMessage":"No facilitator registered for scheme: exact and network: stellar:pubnet",
- "error":"No facilitator registered for scheme: exact and network: stellar:pubnet"}
-```
-
-A client asking for an unsupported combination has made a **client** error, and
-`/supported` already publishes the correct answer. Returning `500` tells every
-well-behaved HTTP client that the *server* failed and the request should be
-retried — so a stock client will hammer a facilitator that will never say yes.
-
-Worse, `x402Version: 1` with `network: stellar:testnet` produces the same 500
-with the message *"No facilitator registered for scheme: exact and network:
-stellar:testnet"* — which is **untrue as written**. That pair is registered; it
-is registered at `x402Version: 2`. The message names the scheme and network but
-omits the version, which is the field that actually caused the miss, and so
-misdirects anyone debugging it.
-
-### 2. Rejections carry no `invalidMessage`
-
-Every structured rejection is exactly `{"isValid":false,"invalidReason":"…"}`,
-sometimes with `payer`. The `invalidMessage` field is **absent entirely** — not
-null, not empty. It appears only on the `500`/`400` paths, which are the ones a
-human is least likely to need it on. So the rejections that matter carry a
-machine-readable code and no human-readable detail.
-
-### 3. Already-expired and replayed payloads are indistinguishable
-
-Both report `invalid_exact_stellar_payload_simulation_failed`, which is also what
-an insufficient balance or a stale ledger state reports. These need different
-client responses — re-sign with a fresh expiration (retryable) versus stop, the
-payment is already spent (terminal) — and a client cannot tell them apart. The
-spec has explicit rules for expiry, so a specific reason is available.
-
-### 4. The `payer` field is echoed inconsistently
-
-`payer` comes back on `wrong_recipient`, `wrong_amount`, `unsupported_credential_type`,
-`simulation_failed` and on success — but **not** on `wrong_asset`. A resource
-server keying its own bookkeeping off `payer` will find it missing for exactly
-one rejection class.
-
-### 5. `/supported` mixes CAIP-2 and legacy network identifiers
-
-Covered above: the `x402Version: 1` rows use `base-sepolia` and `solana-devnet`.
-Defensible as legacy compatibility, but it means "parse `network` as CAIP-2" is
-wrong against this endpoint unless the version is checked first.
-
-## Other facilitators
-
-### `facilitator.stellar.org` — does not exist
-
-**This is Lens's own hard-coded default.** `src/middleware/x402.ts` and
-`src/api/websocket.ts` both fall back to `https://facilitator.stellar.org` when
-`X402_FACILITATOR_URL` is unset.
-
-The host does not resolve. Google Public DNS returns `Status: 3` (NXDOMAIN) for
-`facilitator.stellar.org.`, with the SOA for `stellar.org.` in the authority
-section — the parent zone exists, the label does not:
-
-```
-$ curl 'https://dns.google/resolve?name=facilitator.stellar.org&type=A'
-{"Status":3, ... "Authority":[{"name":"stellar.org.","type":6, ...}]}
-```
-
-This is precisely the "advertised support and reachable support are not the same
-thing" gap the RFP describes, except it is ours. Any deployment of Lens that has
-not set `X402_FACILITATOR_URL` is gating paid routes behind a facilitator that
-cannot be reached. Tracked separately — it is a Lens bug, not a conformance
-finding, and it should be fixed before it reaches anyone's deployment.
-
-### Coverage limits
-
-No other facilitator advertising Stellar support was reachable without
-credentials at the time of writing. Coinbase's facilitator requires an API key,
-which puts it outside the "same stock client, no privileged access" bar this
-document holds itself to. When a second Stellar-serving facilitator becomes
-publicly reachable, the tables above are the harness to re-run against it.
-
-## What this means for Lens's facilitator
-
-Concrete requirements for #124, #125 and #126, derived from the gaps above
-rather than from taste:
-
-1. **Never return `5xx` for a client error.** Unsupported scheme, network or
-   version is a rejection with a reason, not a server fault. This is finding 1
-   and it is the one most likely to cause real interop pain.
-2. **Include the version in any "not supported" message**, since version is a
-   routing dimension and omitting it produces actively false messages.
-3. **Populate `invalidMessage` on every rejection.** The code is for the machine;
-   the message is what saves an integrator an afternoon.
-4. **Give expiry and replay their own reasons.** `simulation_failed` should mean
-   "simulation failed for a reason I could not classify", not "one of four
-   completely different things".
-5. **Echo `payer` on every response that knows it**, without exception.
-6. **Match the reasons that already work**: `wrong_recipient`, `wrong_asset`,
-   `wrong_amount`, `signature_expiration_too_far` and
-   `unsupported_credential_type` are all specific and correct in the reference
-   implementation. Lens should emit the same identifiers for the same conditions
-   so a client can treat both facilitators uniformly — that is what conformance
-   is for.
-
-## Reproducing this
-
-The client is stock `@stellar/stellar-sdk` 16.2.0 driving the flow the spec
-describes:
-
-1. Build an `invokeHostFunction` calling `transfer(from, to, amount)` on the SAC.
-2. `simulateTransaction` to obtain the required auth entries.
-3. `authorizeEntry(entry, payerKeypair, currentLedger + ceil(maxTimeoutSeconds / 5), passphrase)`.
-4. `assembleTransaction`, then replace the operation's auth with the signed entries.
-5. `toXDR()` into `payload.transaction`, and POST to `/verify`, then `/settle`.
-
-One detail worth recording, because it costs an hour to find: **the transaction
-source account must differ from the payer.** If the client builds the transaction
-with the payer as source, Soroban simulation returns a
-`sorobanCredentialsSourceAccount` auth entry, and the facilitator correctly
-rejects it with `invalid_exact_stellar_payload_unsupported_credential_type` —
-spec §3 permits `sorobanCredentialsAddress` only. Using any other funded account
-as the source makes simulation emit an address credential for the payer, which
-is what the sponsored flow requires. The spec implies this but does not say it
-outright.
+# x402 conformance: baseline against the public facilitator
+
+A record of what the **public `x402.org` facilitator actually does** on
+`stellar:testnet`, established by pointing a canonical client at it and feeding
+it deliberately bad input. This is the baseline Lens's own facilitator (#124,
+#125, #126) is measured against — without it, "conformant" means nothing more
+than our own reading of the spec, which is exactly the drift the RFP screens
+for.
+
+Everything below was executed against live testnet. Nothing here is inferred.
+
+## What was run
+
+| | |
+| --- | --- |
+| Facilitator | `https://x402.org/facilitator` (no API key required) |
+| Network | `stellar:testnet` |
+| Scheme | `exact` |
+| Spec | [`scheme_exact_stellar.md`](https://github.com/x402-foundation/x402/blob/main/specs/schemes/exact/scheme_exact_stellar.md) @ `c4d2de655d1dfca63f54100e32de019b26aaacdd` (2026-07-17, "fix stellar tx fee (#2852)") |
+| Client | `@stellar/stellar-sdk` **16.2.0**, unmodified — stock `simulateTransaction`, `authorizeEntry`, `assembleTransaction`. No patched SDK, no local shims. |
+| Date | 2026-08-31 |
+
+**Scope note, stated plainly:** this is *not* a run of the x402 repository's own
+e2e suite. That suite is not currently runnable against an arbitrary facilitator
+without vendoring its harness. What was done instead is the check the RFP
+actually describes — building a canonical client straight from the published
+spec with the stock SDK, and completing a payment end to end. Where that is a
+weaker signal than running their suite, it is a stronger one than reading the
+spec, and the settled transaction hash below is verifiable by anyone.
+
+## Headline result: a payment settled end to end
+
+A real `exact` payment on `stellar:testnet`, verified and settled by the public
+facilitator, with a client that had never been pointed at it before.
+
+| | |
+| --- | --- |
+| Transaction | [`988dca9e7a204a59534912ff502fd81056f571e35f2cb87812bdfdc3292d9f17`](https://stellar.expert/explorer/testnet/tx/988dca9e7a204a59534912ff502fd81056f571e35f2cb87812bdfdc3292d9f17) |
+| Ledger | 4425809 |
+| Result | `successful: true` |
+| Payer | `GBJ72MK5OQ3N2X2DZGUCBHFZM62UA4W3B7ZKKY53NREMYWBSMLQMBWND` |
+| Recipient | `GD7FSGAFENIMMKU5QZZR76O53NNSL7QQ6NFGROXKA26JX4FYXNN363OF` — balance went to exactly `1.0000000` |
+| Asset | `CDBH3ITPRJRLINW5TKQCEFARO6UCUZZBGPBVT6QGZJ7WQQ2VOTYND2OM` (a SAC deployed for this test) |
+
+**Fee sponsorship is real, not just advertised.** The submitted transaction's
+source account is `GC6CSXBV4C6RL3HEDTW57KXYXSSXKAWKGYDEOSATXM3XNKXSR2VRYN3K` —
+the facilitator's own account, not the payer's — and the 23,059 stroop fee was
+charged to it. `extra.areFeesSponsored: true` is therefore backed by observed
+behaviour. (23,059 stroops also sits comfortably under the spec's 50,000-stroop
+default ceiling.)
+
+## `/supported`, captured verbatim
+
+`GET https://x402.org/facilitator/supported` → `200`. The Stellar entry:
+
+```json
+{ "x402Version": 2, "scheme": "exact", "network": "stellar:testnet", "extra": { "areFeesSponsored": true } }
+```
+
+This matches the RFP's stated contract exactly: the Stellar `extra` block is
+present, `areFeesSponsored` is `true`, and the identifier is CAIP-2.
+
+All 11 advertised kinds:
+
+| x402Version | scheme | network | extra |
+| --- | --- | --- | --- |
+| 2 | `exact` | `eip155:84532` | — |
+| 2 | `upto` | `eip155:84532` | `facilitatorAddress` |
+| 2 | `batch-settlement` | `eip155:84532` | — |
+| 2 | `exact` | `solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1` | `feePayer`, `features.smartWalletSupported` |
+| 2 | `exact` | `algorand:SGO1GKSzyE7IEPItTxCByw9x8FmnrCDe` | `feePayer` |
+| 2 | `exact` | `aptos:2` | `feePayer` |
+| 2 | `exact` | **`stellar:testnet`** | `areFeesSponsored: true` |
+| 2 | `exact` | `hedera:testnet` | `feePayer` |
+| 2 | `exact` | `xrpl:1` | `areFeesSponsored: false` |
+| 1 | `exact` | `base-sepolia` | — |
+| 1 | `exact` | `solana-devnet` | — |
+
+Two things to note. **Stellar mainnet is not served** — `stellar:testnet` is the
+only Stellar entry, so nothing about mainnet behaviour can be inferred from this
+facilitator. And **CAIP-2 holds only for `x402Version: 2`**: the two v1 entries
+use the legacy non-CAIP-2 names `base-sepolia` and `solana-devnet`. A client that
+reads `/supported` and assumes CAIP-2 throughout will mis-parse those two rows.
+
+## Rejection reasons: does every rejection carry one?
+
+The RFP's requirement is that every rejection carries a non-null `reason`. Fed
+deliberately bad input, the answer is **yes for `invalidReason`, and no for
+anything human-readable**. Results, all live:
+
+### Structural checks against a real signed payload
+
+Each of these starts from the *same* valid payload that settled above, with one
+field changed — so a specific reason is genuinely available to the facilitator.
+
+| Input | HTTP | `invalidReason` | Verdict |
+| --- | --- | --- | --- |
+| Control, unmodified | 200 | — (`isValid: true`) | ✅ |
+| `requirements.payTo` ≠ transaction's `to` | 200 | `invalid_exact_stellar_payload_wrong_recipient` | ✅ specific |
+| `requirements.asset` ≠ transaction's contract | 200 | `invalid_exact_stellar_payload_wrong_asset` | ✅ specific |
+| `requirements.amount` ≠ transaction's amount | 200 | `invalid_exact_stellar_payload_wrong_amount` | ✅ specific |
+| Auth expiration `+100` ledgers (cap is `+12`) | 200 | `invalid_exact_stellar_signature_expiration_too_far` | ✅ specific |
+| Auth expiration `+1000` | 200 | `invalid_exact_stellar_signature_expiration_too_far` | ✅ specific |
+| Auth expiration `+100000` | 200 | `invalid_exact_stellar_signature_expiration_too_far` | ✅ specific |
+| **Auth expiration 50 ledgers in the past** | 200 | `invalid_exact_stellar_payload_simulation_failed` | ⚠️ generic |
+| **Replay of the already-settled payload** | 200 | `invalid_exact_stellar_payload_simulation_failed` | ⚠️ generic |
+| Source-account auth credential (not address) | 200 | `invalid_exact_stellar_payload_unsupported_credential_type` | ✅ specific |
+
+Spec §3's expiration ceiling is enforced properly, with its own named reason. The
+opposite direction is not: an entry that has **already expired** is caught only
+when simulation fails, and reports the same generic reason as a replay, an
+insufficient balance, or any other state problem.
+
+### Malformed payloads
+
+| Input | HTTP | `invalidReason` |
+| --- | --- | --- |
+| Empty body | 400 | `missing_parameters` |
+| `paymentPayload` only | 400 | `missing_parameters` |

+| Payload/requirements network mismatch | 200 | `network_mismatch` |
+| Missing `payload.transaction` | 200 | `invalid_exact_stellar_payload_malformed` |
+| `transaction` not base64 | 200 | `invalid_exact_stellar_payload_malformed` |
+| `transaction` valid base64, not XDR | 200 | `invalid_exact_stellar_payload_malformed` |
+| `transaction` empty string | 200 | `invalid_exact_stellar_payload_malformed` |
+| **`x402Version: 1` on `stellar:testnet`** | **500** | `unexpected_error` |
+| **`network: stellar:pubnet` (not advertised)** | **500** | `unexpected_error` |
+| **`scheme: upto` on Stellar (not advertised)** | **500** | `unexpected_error` |
+
+### `payload: { transaction }` accepted verbatim?
+
+**Yes.** The spec's `payload` shape was sent exactly as published — a single
+`transaction` key holding base64 XDR — inside the spec's full `PaymentPayload`

+
+**This is Lens's own hard-coded default.** `src/middleware/x402.ts` and
+`src/api/websocket.ts` both fall back to `https://facilitator.stellar.org` when
+`X402_FACILITATOR_URL` is unset.

+
+This is precisely the "advertised support and reachable support are not the same

+
+## Reproducing this
+

+
+1. Build an `invokeHostFunction` calling `transfer(from, to, amount)` on the SAC.

+4. `assembleTransaction`, then replace the operation's auth with the signed entries.
+5. `toXDR()` into `payload.transaction`, and POST to `/verify`, then `/settle`.
+
+One detail worth recording, because it costs an hour to find: **the transaction
+source account must differ from the payer.** If the client builds the transaction
+with the payer as source, Soroban simulation returns a
+`sorobanCredentialsSourceAccount` auth entry, and the facilitator correctly
+rejects it with `invalid_exact_stellar_payload_unsupported_credential_type` —
+spec §3 permits `sorobanCredentialsAddress` only. Using any other funded account
+as the source makes simulation emit an address credential for the payer, which
+is what the sponsored flow requires. The spec implies this but does not say it
+outright.

-# Bazaar catalog integrity
-
-The Bazaar catalog is written from the payment payload. Clients echo the
-resource block into it, so the facilitator is a trust boundary: **anyone who
-can pay can attempt to write to the index.** This note describes what is
-enforced at that boundary, and what an attacker who is willing to pay can still
-attempt.
-
-## The two doors into the catalog
-
-| Path | Trust | Validation |
-|---|---|---|
-| `registerBazaarResource(input)` | Trusted — Lens listing its own endpoints | None; the caller is us |
-| `submitCatalogListing(input, authority)` | Untrusted — a listing carried by a client's payment | Everything below |
-
-`authority` is `{ payTo, network }` taken from the payment requirements the
-payer signed. It is the one fact about a listing that cannot be forged, and
-every ownership decision is anchored to it.
-
-## What is enforced
-
-**Seller identity.** Every `accepts[].payTo` must equal the payment's own
-`payTo`, and the listing's network must equal the payment's network. A listing
-can therefore only ever speak for the seller that paid to publish it.
-
-**First claim wins.** A resource identity — `(network, url, httpMethod)` for
-HTTP, `(network, url, toolName)` for MCP — belongs to the `payTo` that
-registered it first. Its owner can update it forever; anyone else is refused,
-which is what stops a payer from repointing another seller's entry at their own
-endpoint or pricing.
-
-**`routeTemplate`, decoded before it is checked.** The template is
-percent-decoded to a fixed point *first*, and the traversal checks run on the
-decoded form. `%2e%2e%2f` is `../`; a validator that inspects the raw string and
-decodes later waves it straight through, and one that decodes only once is
-defeated by `%252e%252e%252f`. A value still changing after four decode passes
-is dropped rather than decoded further. The decoded form is what gets stored, so
-the value served is the value that was validated. Beyond traversal, a template
-must be a path (no scheme, no `//`, no query or fragment, no backslash, no
-control characters), must use `:param` names matching
-`[A-Za-z_][A-Za-z0-9_]*` without repeats, and must structurally describe the
-path of `resource.url` — otherwise a listing could consolidate itself under
-another seller's route family.
-
-**Field limits.** Length, type and character-class limits on every stored
-field (see `CATALOG_LIMITS` in `src/bazaar/validation.ts`), a byte ceiling on
-`bazaar.info` and `bazaar.schema`, `https` only for `resource.url` and
-`iconUrl` with no embedded credentials, atomic-unit amounts, and a bounded
-`maxTimeoutSeconds`. An unbounded description is both a storage problem and a
-search-ranking problem.
-
-**Rate limiting per `payTo`.** `BAZAAR_CATALOG_WRITES_PER_MIN` (default 10) and
-`BAZAAR_CATALOG_WRITES_PER_DAY` (default 200). The attempt is counted before
-the decision, so a rejected write still costs its slot. If Redis is
-unreachable the limiter fails **closed** — at a trust boundary, "I cannot tell
-whether this payer is flooding" is not a reason to accept the write. The
-payment is unaffected either way.
-
-**Untrusted at read time too.** Control characters are stripped when a row is
-served, not only when it is written: rows predate this validation, and a value
-that is harmless inside JSON can still be harmful to whatever renders it.
-
-## Soft drop
-
-Invalid metadata never fails the payment. The payment is legitimate; only the
-listing is bad. `submitCatalogListing` returns
-`{ accepted, drops }` and never throws, and `toExtensionResponses(drops)`
-builds the `EXTENSION-RESPONSES` body so the seller is told which field was
-rejected and why:
-
-```json
-{
-  "bazaar": {
-    "catalog": {
-      "accepted": false,
-      "drops": [
-        {

+# Bazaar catalog integrity
+
+The Bazaar catalog is written from the payment payload. Clients echo the
+resource block into it, so the facilitator is a trust boundary: **anyone who
+can pay can attempt to write to the index.** This note describes what is
+enforced at that boundary, and what an attacker who is willing to pay can still
+attempt.
+
+## The two doors into the catalog
+
+| Path | Trust | Validation |
+|---|---|---|
+| `registerBazaarResource(input)` | Trusted — Lens listing its own endpoints | None; the caller is us |
+| `submitCatalogListing(input, authority)` | Untrusted — a listing carried by a client's payment | Everything below |
+
+`authority` is `{ payTo, network }` taken from the payment requirements the
+payer signed. It is the one fact about a listing that cannot be forged, and
+every ownership decision is anchored to it.
+
+## What is enforced
+
+**Seller identity.** Every `accepts[].payTo` must equal the payment's own
+`payTo`, and the listing's network must equal the payment's network. A listing
+can therefore only ever speak for the seller that paid to publish it.
+
+**First claim wins.** A resource identity — `(network, url, httpMethod)` for
+HTTP, `(network, url, toolName)` for MCP — belongs to the `payTo` that
+registered it first. Its owner can update it forever; anyone else is refused,
+which is what stops a payer from repointing another seller's entry at their own
+endpoint or pricing.
+
+**`routeTemplate`, decoded before it is checked.** The template is
+percent-decoded to a fixed point *first*, and the traversal checks run on the
+decoded form. `%2e%2e%2f` is `../`; a validator that inspects the raw string and
+decodes later waves it straight through, and one that decodes only once is
+defeated by `%252e%252e%252f`. A value still changing after four decode passes
+is dropped rather than decoded further. The decoded form is what gets stored, so
+the value served is the value that was validated. Beyond traversal, a template
+must be a path (no scheme, no `//`, no query or fragment, no backslash, no
+control characters), must use `:param` names matching
+`[A-Za-z_][A-Za-z0-9_]*` without repeats, and must structurally describe the
+path of `resource.url` — otherwise a listing could consolidate itself under
+another seller's route family.
+
+**Field limits.** Length, type and character-class limits on every stored
+field (see `CATALOG_LIMITS` in `src/bazaar/validation.ts`), a byte ceiling on
+`bazaar.info` and `bazaar.schema`, `https` only for `resource.url` and
+`iconUrl` with no embedded credentials, atomic-unit amounts, and a bounded
+`maxTimeoutSeconds`. An unbounded description is both a storage problem and a
+search-ranking problem.
+
+**Rate limiting per `payTo`.** `BAZAAR_CATALOG_WRITES_PER_MIN` (default 10) and
+`BAZAAR_CATALOG_WRITES_PER_DAY` (default 200). The attempt is counted before
+the decision, so a rejected write still costs its slot. If Redis is
+unreachable the limiter fails **closed** — at a trust boundary, "I cannot tell
+whether this payer is flooding" is not a reason to accept the write. The
+payment is unaffected either way.
+
+**Untrusted at read time too.** Control characters are stripped when a row is
+served, not only when it is written: rows predate this validation, and a value
+that is harmless inside JSON can still be harmful to whatever renders it.
+
+## Soft drop
+
+Invalid metadata never fails the payment. The payment is legitimate; only the
+listing is bad. `submitCatalogListing` returns
+`{ accepted, drops }` and never throws, and `toExtensionResponses(drops)`
+builds the `EXTENSION-RESPONSES` body so the seller is told which field was
+rejected and why:
+
+```json
+{
+  "bazaar": {
+    "catalog": {
+      "accepted": false,
+      "drops": [
+        {
+          "field": "extensions.bazaar.routeTemplate",
+          "code": "path_traversal",
+          "message": "routeTemplate contains a path traversal segment."
+        }
+      ]
+    }
+  }
+}
+```
+
+`code` is stable and machine-readable — an agent branches on it rather than
+parsing `message`. `message` never echoes the offending value back.
+
+## What an attacker who can pay can still attempt
+
+- **Squatting an unclaimed identity.** First claim wins, so a payer can
+  register a URL they do not operate, as long as nobody registered it first.
+  What they cannot do is claim someone else's `payTo`, so the listing is
+  attributable and revocable. Binding a listing to proof of control over its
+  domain would close this, and is not in this change.

-# Declaring a discoverable, priced endpoint
-
-Seller-side helpers for the x402 Bazaar discovery extension. The goal from §3.6
-of the RFP: **from docs to a paid, discoverable endpoint in well under an hour.**
-
-## Why per-parameter descriptions are the whole point
-
-The buyer is software. An agent choosing between two price feeds cannot open
-your docs — it has only what your listing declares. `GET /price/:assetA/:assetB`
-tells it almost nothing. The same endpoint with each parameter's accepted form
-spelled out, the response described, and the price stated is *selectable*.
-
-Ranking (#129) can only rank on what is declared, so metadata quality is the
-ceiling on search quality no matter how good the retrieval is. That is why
-`description` is the **first positional argument** of every parameter
-constructor, and why a declaration missing one does not validate. It is not a
-warning you can ship past.
-
-## The short version
-
-```ts
-import { declareHttpResource, assertDeclaration, param } from './bazaar/declare'
-
-const pathParams = {
-  assetA: param.string('Base asset, as "XLM" or "CODE:ISSUER".', { example: 'XLM' }),
-  assetB: param.string('Quote asset, same form as assetA. Price is assetA in assetB.'),
-}
-
-export const priceListing = assertDeclaration(
-  declareHttpResource({
-    url: 'https://lens.example/price/:assetA/:assetB',
-    method: 'GET',
-    network: 'testnet',
-    routeTemplate: '/price/:assetA/:assetB',
-    description: 'Unified Stellar price for an asset pair, across SDEX and AMM pools.',
-    accepts: [{ scheme: 'exact', amount: '100000', asset: 'USDC', payTo: PAY_TO, maxTimeoutSeconds: 60 }],
-    pathParams,
-    output: { type: 'object', properties: { price: { type: 'string', description: 'Mid price, decimal string.' } } },
-  }),
-  { pathParams, routeTemplate: '/price/:assetA/:assetB' },
-)
-```
-
-That is the whole declaration. It produces a complete
-`RegisterBazaarResourceInput` — resource block, `accepts`, and the
-`extensions.bazaar` declaration with a proper JSON Schema — and throws at module
-load if anything is wrong.
-
-## Parameters
-
-| Constructor | Emits |
-| --- | --- |
-| `param.string(description, opts?)` | `{ type: 'string', description }` |
-| `param.number(description, opts?)` | `{ type: 'number', description }` |
-| `param.integer(description, opts?)` | `{ type: 'integer', description }` |
-| `param.boolean(description, opts?)` | `{ type: 'boolean', description }` |
-| `param.enumOf(values, description, opts?)` | `{ type: 'string', enum: values, description }` |
-
-`opts` takes `required` (default `true`), `example` and `default`. An `example`
-is worth more to an agent than another sentence of prose — give it a value it
-can copy.
-
-Parameters go into `pathParams`, `queryParams` (GET/HEAD/DELETE) or `body`
-(POST/PUT/PATCH); the helper picks the right slot from the method and sets
-`bodyType` for you. Each set becomes a JSON Schema object with
-`additionalProperties: false` and a `required` list built from the flags.
-
-## MCP tools
-
-Same idea, one call:
-
-```ts
-declareMcpTool({
-  url: 'https://lens.example/mcp',
-  network: 'testnet',
-  toolName: 'get_price',
-  transport: 'streamable-http',
-  description: 'Unified Stellar price for an asset pair.',
-  accepts,
-  input: { assetA: param.string('Base asset, as "XLM" or "CODE:ISSUER".') },
-})
-```
-
-## Validation happens before anything is sent
-
-`validateDeclaration(listing, spec)` returns
-`{ ok: true, listing }` or `{ ok: false, problems }`. Each problem carries the
-same `{ field, code, message }` shape the catalog uses for soft drops, so what
-you see locally is what the catalog would have told you — except you see it at
-development time rather than in an `EXTENSION-RESPONSES` header in production.
-
-It runs the catalog's **own** `validateListing` under the hood, so the two
-cannot drift apart, then adds the rules the catalog cannot enforce because by
-then the metadata is all it has:
-
-| Code | Meaning |
-| --- | --- |
-| `missing_param_description` | A parameter has no description |
-| `param_description_too_short` | Under 12 characters — name the accepted values, not the field |
-| `weak_resource_description` | The resource description is missing or too short to rank on |
-| `undeclared_route_param` | `routeTemplate` names a `:param` absent from `pathParams` |
-| `missing_accepts` | No payment requirement — not discoverable as a paid endpoint |
-
-`assertDeclaration()` is the same check that throws, listing every problem with
-its field path. Call it at module load on your own listings: a malformed listing
-then fails the boot, instead of quietly never appearing in the Bazaar.
-
-## Lens's own endpoints
-
-`src/bazaar/lensListings.ts` declares the routes `src/middleware/x402.ts` gates
-— `/price/:assetA/:assetB`, `/candles/:assetA/:assetB`, `/pools` and
-`/price/twap/:assetA/:assetB` — using exactly these helpers, with the MCP face
-of the price feed alongside. They go through `assertDeclaration` at module load.
-If declaring metadata for our own price feed were awkward, it would be awkward
-for everyone, and this is where we would find that out.

-# Scheme: `upto` on `Stellar`
-
-> Draft specification for the x402 `upto` scheme on Stellar. Stellar currently
-> has a specified `exact` scheme upstream but no `upto` scheme; this document
-> proposes one, matching the format of the existing `exact` Stellar spec and
-> the `upto` specs for EVM and SVM in the
-> [x402 protocol repository](https://github.com/x402-foundation/x402).
-
-## Versions supported
-
-- ❌ `v1` - we don't plan to support v1 for now.
-- ✅ `v2`
-
-## Supported Networks
-
-This spec uses [CAIP-2](https://namespaces.chainagnostic.org/stellar/caip2) identifiers:
-- `stellar:pubnet` — Stellar mainnet
-- `stellar:testnet` — Stellar testnet
-
-## Summary
-
-The x402 `upto` scheme on Stellar authorizes a transfer of up to a **maximum amount**, with the actual amount settled after resource consumption is known. As with [`exact` on Stellar][scheme-exact-stellar], the client authorizes via a signed Soroban authorization entry rather than a full transaction signature, and the facilitator sponsors transaction fees.
-
-> [!NOTE]
-> **Scope:** This spec covers [SEP-41]-compliant Soroban tokens **only**. Classic Stellar assets are not supported, matching [`exact` on Stellar][scheme-exact-stellar].
-
-## Contract-vs-No-Contract Decision
-
-**This spec ships a Soroban contract: `x402UptoStellar`.**
-
-A bare [SEP-41] `approve` / `transfer_from` allowance cannot, on its own, provide the three guarantees the [`upto` core spec][scheme-upto] requires of every network implementation:
-
-- **Recipient binding** — a SEP-41 allowance authorizes a `spender` to move up to `amount`, to *any* address that spender chooses. It does not bind the transfer to a specific `payTo`.
-- **Single-use authorization** — a SEP-41 allowance is a standing balance the spender can draw down across many calls; it has no built-in single-settlement or replay-protection semantics.
-- **Time-bound authorization with an explicit `validAfter`/deadline pair** — SEP-41's `approve` supports an expiration ledger, but not a `validAfter` start bound, and nothing stops the spender from settling more than once before expiry.
-
-This mirrors the precedent already set by the two implemented networks: EVM does not rely on a bare ERC-20 `approve` either — it ships the purpose-built `x402UptoPermit2Proxy` contract, which wraps Permit2's witness pattern to add recipient binding, a nonce, and settle-time cap enforcement. SVM ships the `payment-channels` program for the same reason. A Stellar design that stopped at "the client approves the facilitator" would be strictly weaker than both existing implementations, not merely different from them — so this spec does not offer a contract-free path.
-
-The `x402UptoStellar` contract is intentionally thin: it does not escrow the client's funds up front (unlike SVM's channel model). Instead, it composes with a standard SEP-41 `approve`, and adds the missing recipient binding, nonce, and cap enforcement as a signed-authorization wrapper around `transfer_from`, closer in spirit to the EVM Permit2 witness pattern than to SVM's escrow. This keeps capital efficient (no funds are locked before settlement) and keeps the per-request signing step off-chain and free, consistent with how `exact` on Stellar already uses auth-entry signing instead of on-chain transactions for the client's half of the flow.
-
-## Summary of the Flow
-
-1. **Client** performs a one-time (or periodic) [SEP-41] `approve(spender: <x402UptoStellar contract address>, amount: <allowance ceiling>, expiration_ledger)` on the token contract. This is an on-chain transaction, analogous to EVM's Phase 1 Permit2 approval — it is not part of the per-request payment flow and is skipped on subsequent requests while the allowance remains sufficient and unexpired.
-2. **Resource Server** responds `402 Payment Required` with `PaymentRequirements` for `upto`, including `extra.uptoContract` (the `x402UptoStellar` contract address) and `extra.facilitatorAddress`.
-3. **Client** signs a Soroban authorization entry for `x402UptoStellar.settle_upto(from, to, asset, max_amount, facilitator, nonce, expiration_ledger)`, with `max_amount` set to the authorized ceiling for this request (this is the `PaymentRequirements.amount` field at verification time), `to` set to `requirements.payTo`, and `facilitator` set to `extra.facilitatorAddress`. Expiration is derived from `maxTimeoutSeconds` exactly as in `exact` on Stellar.
-4. **Client** serializes the signed authorization entry (base64 XDR) and sends it to the resource server as the `PaymentPayload`.
-5. **Resource Server** forwards the payload to the **Facilitator**'s `/verify` endpoint, which checks the authorization entry's structure, expiration, and that `requirements.amount <= max_amount`, without settling.
-6. **Resource Server** executes the request, determines the actual cost, and calls the facilitator's `/settle` endpoint with `requirements.amount` set to the actual amount (phase-dependent `amount`, per the [`upto` core spec][scheme-upto] §5).
-7. **Facilitator** re-verifies the client's authorization entry against `max_amount` (the signed ceiling, not the settlement-time amount — see [Settle-Time Verification](#settle-time-verification)), then calls `x402UptoStellar.settle_upto(auth_entry, actual_amount)`.
-8. **Contract** checks the nonce has not been used, `now <= expiration_ledger`, `facilitator.require_auth()` matches the signed `facilitator`, and `actual_amount <= max_amount`; it then calls `token.transfer_from(spender: self, from, to, actual_amount)` and marks the nonce consumed.
-9. **Facilitator** submits the transaction, sponsoring fees as in `exact`, and returns a `SettlementResponse` to the **Resource Server**, which grants access to the **Client**.

-## `PaymentRequirements` for `upto`
-
-```json
-{
-  "scheme": "upto",
-  "network": "stellar:testnet",
-  "amount": "10000000",
-  "asset": "CBIELTK6YBZJU5UP2WWQEUCYKLPU6AUNZ2BQ4WWFEIE3USCIHMXQDAMA",
-  "payTo": "GBHEGW3KWOY2OFH767EDALFGCUTBOEVBDQMCKU4APMDLQNBW5QV3W3KO",
-  "maxTimeoutSeconds": 300,
-  "extra": {
-    "areFeesSponsored": true,
-    "uptoContract": "CA...UPTOSTELLARCONTRACTADDRESS",
-    "facilitatorAddress": "GBFACILITATOR..."
-  }
-}
-```
-
-**Field Definitions:**
-
-- `amount`: Phase-dependent per the [`upto` core spec][scheme-upto] — the authorized maximum at verification time, the actual settlement amount at settlement time.
-- `extra.uptoContract`: The deployed `x402UptoStellar` contract address the client must authorize against.
-- `extra.facilitatorAddress`: The facilitator the client binds into the signed authorization (mirrors EVM's `witness.facilitator`); prevents settlement by any other party.
-- `extra.areFeesSponsored`: As in `exact` — currently always `true`.
-
-## PaymentPayload `payload` Field
-
-```json
-{
-  "authEntry": "AAAAAgAAAABriIN4poutFUmHfB6FbFJu8GgXoPPTGQWREqFpPfvO1AAAAAAAAAAAAAAAAAAAAA...",
-  "nonce": "3f1a...b2",
-  "maxAmount": "10000000"
-}
-```
-
-- `authEntry`: Base64-encoded XDR of the signed Soroban authorization entry for `settle_upto`.
-- `nonce`: The 32-byte nonce bound into the authorization entry, surfaced separately so the facilitator can perform a fast pre-check without decoding XDR.
-- `maxAmount`: The signed ceiling, echoed outside the XDR for the same reason.
-
-## Facilitator Verification Rules (MUST)
-
-### 1. Protocol Validation
-
-Same as `exact` on Stellar: `x402Version` MUST be `2`, `scheme` MUST be `"upto"` on both sides, `network` MUST match.
-
-### 2. Authorization Entry Structure
-
-- The authorization entry MUST target the `x402UptoStellar` contract at `extra.uptoContract` and the `settle_upto` function.
-- Arguments MUST be exactly `(from, to, asset, max_amount, facilitator, nonce, expiration_ledger)`.
-- `to` MUST equal `requirements.payTo` exactly.
-- `asset` MUST equal `requirements.asset` exactly.
-- `facilitator` MUST equal `extra.facilitatorAddress` exactly.
-- Credential type MUST be `sorobanCredentialsAddress`, matching `exact`.
-
-### 3. Cap and Amount Rules
-
-- At **verify** time: `requirements.amount` (the authorized maximum) MUST equal the signed `max_amount`.
-- At **settle** time: `requirements.amount` (the actual settlement amount) MUST be `<= max_amount` from the signed entry. The facilitator MUST re-verify the authorization entry's signature against `max_amount`, never against the settlement-time amount — see [Settle-Time Verification](#settle-time-verification).
-- The settled amount MAY be `0`.
-
-### 4. Time Bounds and Replay
-
-- `expiration_ledger` MUST NOT exceed `currentLedger + ceil(maxTimeoutSeconds / estimatedLedgerSeconds)` (fallback `5` seconds/ledger, as in `exact`).
-- The facilitator MUST query the contract's nonce state (or simulate `settle_upto`) before submitting, to short-circuit already-consumed nonces.
-- The contract itself is the source of truth for replay protection: `settle_upto` MUST fail if `nonce` has already been marked consumed.
-
-### 5. 🚨🚨🚨 Facilitator Safety
-
-Same as `exact` §4: the facilitator's own address MUST NOT be `from`, MUST NOT appear as an unexpected signer, and simulation MUST show only the expected balance change (`from` decrease of `actual_amount`, `to` increase of `actual_amount`) plus no other balance changes.
-
-### 6. Allowance Precondition
-
-- Before verification can succeed, the facilitator MUST confirm `token.allowance(from, uptoContract) >= max_amount` and unexpired. If insufficient, the facilitator MUST return `412 Precondition Failed` with an error code equivalent to EVM's `PERMIT2_ALLOWANCE_REQUIRED`, signaling the client to submit the one-time `approve` first.
-
-## Settle-Time Verification
-
-Identical rationale to [EVM `upto` §Settle-Time Verification][scheme-upto-evm-settle]: because `amount` is phase-dependent, the facilitator MUST:
-
-1. Verify the authorization entry's signature against the signed `max_amount` (the ceiling), not `requirements.amount` (the actual settlement amount) — the client signed for the ceiling, and comparing against the metered amount would reject every partial settlement.
-2. Validate `requirements.amount <= max_amount`.
-3. Call `settle_upto` with `actual_amount = requirements.amount`.
-
-A facilitator that instead enforces `requirements.amount === max_amount` at settle time will reject all partial settlements, breaking the core `upto` value proposition.

-## `x402UptoStellar` Contract
-
-Reference behavior (Soroban, Rust):
-
-- `settle_upto(from: Address, to: Address, asset: Address, max_amount: i128, facilitator: Address, nonce: BytesN<32>, expiration_ledger: u32, actual_amount: i128)`
-  - Requires `from`'s authorization on this invocation with the fixed args `(from, to, asset, max_amount, facilitator, nonce, expiration_ledger)` — `actual_amount` is deliberately **not** part of the signed argument set, since it is only known at settle time; this is the Stellar analogue of Permit2's witness/permitted-amount split.
-  - Requires `facilitator.require_auth()`, binding settlement to the designated facilitator.
-  - Fails if `nonce` has already been consumed for `from`.
-  - Fails if `env.ledger().sequence() > expiration_ledger`.
-  - Fails if `actual_amount > max_amount` or `actual_amount < 0`.
-  - On success: calls `token_client.transfer_from(&env.current_contract_address(), &from, &to, &actual_amount)`, marks `nonce` consumed, and emits a `settle` event with `(from, to, asset, actual_amount, nonce)`.
-- Zero settlement (`actual_amount == 0`): the facilitator MAY skip calling `settle_upto` entirely and let the authorization entry expire unused, exactly as EVM's zero-settlement case — no on-chain transaction, no gas cost, the nonce is simply never consumed. If the resource server needs an on-chain record of the zero-charge decision, the facilitator MAY still call `settle_upto` with `actual_amount = 0` to consume the nonce and close out the authorization explicitly.
-
-## Composition with Smart Account Spending Policies
-
-The `x402UptoStellar` contract enforces guarantees about a *single authorization*: it cannot be settled twice, cannot exceed its signed ceiling, and cannot be redirected to a different recipient. It says nothing about how many such authorizations a given signer is allowed to produce in total — that is a separate concern, and on Stellar it is naturally handled one layer up, at the smart account (C-account) level, rather than inside the x402 contract itself.
-
-For an agentic payer whose Stellar account is a smart wallet (e.g. a passkey-backed contract account exposing its own `approve(spender, token, amount, expiry)` policy independent of the underlying SEP-41 token allowance), the composition looks like this:
-
-- The **x402 `upto` authorization** (this spec) bounds a single request: at most `max_amount`, to exactly `payTo`, settleable at most once.
-- The **smart account's own spending policy** bounds the agent's signing key across *all* requests: it governs whether the wallet will co-sign an `approve` or `settle_upto` authorization entry for a given `(spender, token)` pair at all, independent of what any individual x402 authorization says.
-
-These two layers are enforced at different points and do not need to agree on mechanism: the smart account's policy check happens client-side, when the wallet decides whether to produce a signature for the agent's requested authorization entry; the `x402UptoStellar` contract's checks happen on-chain, at settle time, regardless of what kind of account `from` is. An agent authorized up to a per-request cap by `upto`, running against a smart wallet with its own aggregate spending policy, is bounded by both: the smart wallet refuses to keep signing once its own policy limit is reached, even if individual `upto` ceilings would otherwise permit more spend. This is a recommended defense-in-depth pattern for agent use cases, not a protocol requirement — `upto` on Stellar functions identically for a plain G-account payer with no wallet-level policy at all.
-
-## Out of Scope
-
-- **`batch-settlement`**: settling more than once against the same authorization (streaming/pay-per-chunk) is explicitly out of scope for `upto`, per the [core spec][scheme-upto]. Nothing in `x402UptoStellar`'s nonce design forecloses a future `batch-settlement` scheme built on the same escrow/voucher primitives used elsewhere in the ecosystem — that would be a distinct scheme with its own spec.
-- **`auth-capture`**: deferred; the single-settlement nonce model here does not preclude a future two-phase design.
-
-## Error Codes
-
-In addition to the standard x402 error codes:
-
-- **`invalid_upto_stellar_payload_settlement_exceeds_amount`**: attempted settlement amount exceeds the signed `max_amount`.
-- **`invalid_upto_stellar_payload_nonce_consumed`**: the authorization entry's nonce has already been settled.
-- **`invalid_upto_stellar_payload_allowance_required`**: the client has not approved `x402UptoStellar` for at least `max_amount` (see [Allowance Precondition](#6-allowance-precondition)).
-
-## Security Considerations
-
-1. **Maximum amount authorization**: as in EVM/SVM, clients should sign `max_amount` conservatively; the facilitator can settle for any amount up to it.
-2. **Server trust**: `upto` requires trusting the resource server to report actual usage honestly; this is unchanged from the core scheme.
-3. **Allowance ceiling vs per-request ceiling**: the SEP-41 `approve` ceiling and the per-request `max_amount` are independent. Implementations SHOULD keep the allowance close to the expected per-request ceiling and re-approve as needed, rather than approving a large standing balance, to limit exposure if a facilitator or the escrow contract is ever compromised.
-4. **Nonce exhaustion / griefing**: because settlement is optional (zero-settlement need not touch the chain), a malicious client cannot force facilitator gas spend by signing many unused authorizations; only the facilitator's own `/settle` calls cost gas, and it only calls them for its own resource server's confirmed usage.
-5. **Smart account composition**: see [Composition with Smart Account Spending Policies](#composition-with-smart-account-spending-policies) — this is an additive, optional safeguard and its absence does not weaken the guarantees this spec makes about a single authorization.

+# Scheme: `upto` on `Stellar`
+
+> Draft specification for the x402 `upto` scheme on Stellar. Stellar currently
+> has a specified `exact` scheme upstream but no `upto` scheme; this document
+> proposes one, matching the format of the existing `exact` Stellar spec and
+> the `upto` specs for EVM and SVM in the
+> [x402 protocol repository](https://github.com/x402-foundation/x402).
+
+## Versions supported
+
+- ❌ `v1` - we don't plan to support v1 for now.
+- ✅ `v2`
+
+## Supported Networks
+
+This spec uses [CAIP-2](https://namespaces.chainagnostic.org/stellar/caip2) identifiers:
+- `stellar:pubnet` — Stellar mainnet
+- `stellar:testnet` — Stellar testnet
+
+## Summary
+
+The x402 `upto` scheme on Stellar authorizes a transfer of up to a **maximum amount**, with the actual amount settled after resource consumption is known. As with [`exact` on Stellar][scheme-exact-stellar], the client authorizes via a signed Soroban authorization entry rather than a full transaction signature, and the facilitator sponsors transaction fees.
+
+> [!NOTE]
+> **Scope:** This spec covers [SEP-41]-compliant Soroban tokens **only**. Classic Stellar assets are not supported, matching [`exact` on Stellar][scheme-exact-stellar].
+
+## Contract-vs-No-Contract Decision
+
+**This spec ships a Soroban contract: `x402UptoStellar`.**
+
+A bare [SEP-41] `approve` / `transfer_from` allowance cannot, on its own, provide the three guarantees the [`upto` core spec][scheme-upto] requires of every network implementation:
+
+- **Recipient binding** — a SEP-41 allowance authorizes a `spender` to move up to `amount`, to *any* address that spender chooses. It does not bind the transfer to a specific `payTo`.
+- **Single-use authorization** — a SEP-41 allowance is a standing balance the spender can draw down across many calls; it has no built-in single-settlement or replay-protection semantics.
+- **Time-bound authorization with an explicit `validAfter`/deadline pair** — SEP-41's `approve` supports an expiration ledger, but not a `validAfter` start bound, and nothing stops the spender from settling more than once before expiry.
+
+This mirrors the precedent already set by the two implemented networks: EVM does not rely on a bare ERC-20 `approve` either — it ships the purpose-built `x402UptoPermit2Proxy` contract, which wraps Permit2's witness pattern to add recipient binding, a nonce, and settle-time cap enforcement. SVM ships the `payment-channels` program for the same reason. A Stellar design that stopped at "the client approves the facilitator" would be strictly weaker than both existing implementations, not merely different from them — so this spec does not offer a contract-free path.
+
+The `x402UptoStellar` contract is intentionally thin: it does not escrow the client's funds up front (unlike SVM's channel model). Instead, it composes with a standard SEP-41 `approve`, and adds the missing recipient binding, nonce, and cap enforcement as a signed-authorization wrapper around `transfer_from`, closer in spirit to the EVM Permit2 witness pattern than to SVM's escrow. This keeps capital efficient (no funds are locked before settlement) and keeps the per-request signing step off-chain and free, consistent with how `exact` on Stellar already uses auth-entry signing instead of on-chain transactions for the client's half of the flow.
+
+## Summary of the Flow
+
+1. **Client** performs a one-time (or periodic) [SEP-41] `approve(spender: <x402UptoStellar contract address>, amount: <allowance ceiling>, expiration_ledger)` on the token contract. This is an on-chain transaction, analogous to EVM's Phase 1 Permit2 approval — it is not part of the per-request payment flow and is skipped on subsequent requests while the allowance remains sufficient and unexpired.
+2. **Resource Server** responds `402 Payment Required` with `PaymentRequirements` for `upto`, including `extra.uptoContract` (the `x402UptoStellar` contract address) and `extra.facilitatorAddress`.
+3. **Client** signs a Soroban authorization entry for `x402UptoStellar.settle_upto(from, to, asset, max_amount, facilitator, nonce, expiration_ledger)`, with `max_amount` set to the authorized ceiling for this request (this is the `PaymentRequirements.amount` field at verification time), `to` set to `requirements.payTo`, and `facilitator` set to `extra.facilitatorAddress`. Expiration is derived from `maxTimeoutSeconds` exactly as in `exact` on Stellar.
+4. **Client** serializes the signed authorization entry (base64 XDR) and sends it to the resource server as the `PaymentPayload`.
+5. **Resource Server** forwards the payload to the **Facilitator**'s `/verify` endpoint, which checks the authorization entry's structure, expiration, and that `requirements.amount <= max_amount`, without settling.
+6. **Resource Server** executes the request, determines the actual cost, and calls the facilitator's `/settle` endpoint with `requirements.amount` set to the actual amount (phase-dependent `amount`, per the [`upto` core spec][scheme-upto] §5).
+7. **Facilitator** re-verifies the client's authorization entry against `max_amount` (the signed ceiling, not the settlement-time amount — see [Settle-Time Verification](#settle-time-verification)), then calls `x402UptoStellar.settle_upto(auth_entry, actual_amount)`.
+8. **Contract** checks the nonce has not been used, `now <= expiration_ledger`, `facilitator.require_auth()` matches the signed `facilitator`, and `actual_amount <= max_amount`; it then calls `token.transfer_from(spender: self, from, to, actual_amount)` and marks the nonce consumed.
+9. **Facilitator** submits the transaction, sponsoring fees as in `exact`, and returns a `SettlementResponse` to the **Resource Server**, which grants access to the **Client**.

+  }
+}
+```
+
+**Field Definitions:**
+
+- `amount`: Phase-dependent per the [`upto` core spec][scheme-upto] — the authorized maximum at verification time, the actual settlement amount at settlement time.
+- `extra.uptoContract`: The deployed `x402UptoStellar` contract address the client must authorize against.
+- `extra.facilitatorAddress`: The facilitator the client binds into the signed authorization (mirrors EVM's `witness.facilitator`); prevents settlement by any other party.
+- `extra.areFeesSponsored`: As in `exact` — currently always `true`.
+
+## PaymentPayload `payload` Field
+
+```json

+  "nonce": "3f1a...b2",
+  "maxAmount": "10000000"
+}
+```
+
+- `authEntry`: Base64-encoded XDR of the signed Soroban authorization entry for `settle_upto`.
+- `nonce`: The 32-byte nonce bound into the authorization entry, surfaced separately so the facilitator can perform a fast pre-check without decoding XDR.
+- `maxAmount`: The signed ceiling, echoed outside the XDR for the same reason.
+
+## Facilitator Verification Rules (MUST)
+
+### 1. Protocol Validation
+
+Same as `exact` on Stellar: `x402Version` MUST be `2`, `scheme` MUST be `"upto"` on both sides, `network` MUST match.
+
+### 2. Authorization Entry Structure
+
+- The authorization entry MUST target the `x402UptoStellar` contract at `extra.uptoContract` and the `settle_upto` function.
+- Arguments MUST be exactly `(from, to, asset, max_amount, facilitator, nonce, expiration_ledger)`.
+- `to` MUST equal `requirements.payTo` exactly.
+- `asset` MUST equal `requirements.asset` exactly.
+- `facilitator` MUST equal `extra.facilitatorAddress` exactly.
+- Credential type MUST be `sorobanCredentialsAddress`, matching `exact`.
+
+### 3. Cap and Amount Rules
+
+- At **verify** time: `requirements.amount` (the authorized maximum) MUST equal the signed `max_amount`.
+- At **settle** time: `requirements.amount` (the actual settlement amount) MUST be `<= max_amount` from the signed entry. The facilitator MUST re-verify the authorization entry's signature against `max_amount`, never against the settlement-time amount — see [Settle-Time Verification](#settle-time-verification).
+- The settled amount MAY be `0`.
+
+### 4. Time Bounds and Replay
+
+- `expiration_ledger` MUST NOT exceed `currentLedger + ceil(maxTimeoutSeconds / estimatedLedgerSeconds)` (fallback `5` seconds/ledger, as in `exact`).
+- The facilitator MUST query the contract's nonce state (or simulate `settle_upto`) before submitting, to short-circuit already-consumed nonces.
+- The contract itself is the source of truth for replay protection: `settle_upto` MUST fail if `nonce` has already been marked consumed.
+
+### 5. 🚨🚨🚨 Facilitator Safety
+
+Same as `exact` §4: the facilitator's own address MUST NOT be `from`, MUST NOT appear as an unexpected signer, and simulation MUST show only the expected balance change (`from` decrease of `actual_amount`, `to` increase of `actual_amount`) plus no other balance changes.
+
+### 6. Allowance Precondition
+
+- Before verification can succeed, the facilitator MUST confirm `token.allowance(from, uptoContract) >= max_amount` and unexpired. If insufficient, the facilitator MUST return `412 Precondition Failed` with an error code equivalent to EVM's `PERMIT2_ALLOWANCE_REQUIRED`, signaling the client to submit the one-time `approve` first.
+
+## Settle-Time Verification
+
+Identical rationale to [EVM `upto` §Settle-Time Verification][scheme-upto-evm-settle]: because `amount` is phase-dependent, the facilitator MUST:
+
+1. Verify the authorization entry's signature against the signed `max_amount` (the ceiling), not `requirements.amount` (the actual settlement amount) — the client signed for the ceiling, and comparing against the metered amount would reject every partial settlement.
+2. Validate `requirements.amount <= max_amount`.
+3. Call `settle_upto` with `actual_amount = requirements.amount`.
+
+A facilitator that instead enforces `requirements.amount === max_amount` at settle time will reject all partial settlements, breaking the core `upto` value proposition.
+
+## `x402UptoStellar` Contract
+
+Reference behavior (Soroban, Rust):
+
+- `settle_upto(from: Address, to: Address, asset: Address, max_amount: i128, facilitator: Address, nonce: BytesN<32>, expiration_ledger: u32, actual_amount: i128)`
+  - Requires `from`'s authorization on this invocation with the fixed args `(from, to, asset, max_amount, facilitator, nonce, expiration_ledger)` — `actual_amount` is deliberately **not** part of the signed argument set, since it is only known at settle time; this is the Stellar analogue of Permit2's witness/permitted-amount split.
+  - Requires `facilitator.require_auth()`, binding settlement to the designated facilitator.
+  - Fails if `nonce` has already been consumed for `from`.
+  - Fails if `env.ledger().sequence() > expiration_ledger`.
+  - Fails if `actual_amount > max_amount` or `actual_amount < 0`.
+  - On success: calls `token_client.transfer_from(&env.current_contract_address(), &from, &to, &actual_amount)`, marks `nonce` consumed, and emits a `settle` event with `(from, to, asset, actual_amount, nonce)`.
+- Zero settlement (`actual_amount == 0`): the facilitator MAY skip calling `settle_upto` entirely and let the authorization entry expire unused, exactly as EVM's zero-settlement case — no on-chain transaction, no gas cost, the nonce is simply never consumed. If the resource server needs an on-chain record of the zero-charge decision, the facilitator MAY still call `settle_upto` with `actual_amount = 0` to consume the nonce and close out the authorization explicitly.
+
+## Composition with Smart Account Spending Policies
+
+The `x402UptoStellar` contract enforces guarantees about a *single authorization*: it cannot be settled twice, cannot exceed its signed ceiling, and cannot be redirected to a different recipient. It says nothing about how many such authorizations a given signer is allowed to produce in total — that is a separate concern, and on Stellar it is naturally handled one layer up, at the smart account (C-account) level, rather than inside the x402 contract itself.
+
+For an agentic payer whose Stellar account is a smart wallet (e.g. a passkey-backed contract account exposing its own `approve(spender, token, amount, expiry)` policy independent of the underlying SEP-41 token allowance), the composition looks like this:
+
+- The **x402 `upto` authorization** (this spec) bounds a single request: at most `max_amount`, to exactly `payTo`, settleable at most once.
+- The **smart account's own spending policy** bounds the agent's signing key across *all* requests: it governs whether the wallet will co-sign an `approve` or `settle_upto` authorization entry for a given `(spender, token)` pair at all, independent of what any individual x402 authorization says.
+
+These two layers are enforced at different points and do not need to agree on mechanism: the smart account's policy check happens client-side, when the wallet decides whether to produce a signature for the agent's requested authorization entry; the `x402UptoStellar` contract's checks happen on-chain, at settle time, regardless of what kind of account `from` is. An agent authorized up to a per-request cap by `upto`, running against a smart wallet with its own aggregate spending policy, is bounded by both: the smart wallet refuses to keep signing once its own policy limit is reached, even if individual `upto` ceilings would otherwise permit more spend. This is a recommended defense-in-depth pattern for agent use cases, not a protocol requirement — `upto` on Stellar functions identically for a plain G-account payer with no wallet-level policy at all.
+
+## Out of Scope
+
+- **`batch-settlement`**: settling more than once against the same authorization (streaming/pay-per-chunk) is explicitly out of scope for `upto`, per the [core spec][scheme-upto]. Nothing in `x402UptoStellar`'s nonce design forecloses a future `batch-settlement` scheme built on the same escrow/voucher primitives used elsewhere in the ecosystem — that would be a distinct scheme with its own spec.
+- **`auth-capture`**: deferred; the single-settlement nonce model here does not preclude a future two-phase design.
+
+## Error Codes
+
+In addition to the standard x402 error codes:
+
+- **`invalid_upto_stellar_payload_settlement_exceeds_amount`**: attempted settlement amount exceeds the signed `max_amount`.
+- **`invalid_upto_stellar_payload_nonce_consumed`**: the authorization entry's nonce has already been settled.
+- **`invalid_upto_stellar_payload_allowance_required`**: the client has not approved `x402UptoStellar` for at least `max_amount` (see [Allowance Precondition](#6-allowance-precondition)).
+
+## Security Considerations
+
+1. **Maximum amount authorization**: as in EVM/SVM, clients should sign `max_amount` conservatively; the facilitator can settle for any amount up to it.
+2. **Server trust**: `upto` requires trusting the resource server to report actual usage honestly; this is unchanged from the core scheme.
+3. **Allowance ceiling vs per-request ceiling**: the SEP-41 `approve` ceiling and the per-request `max_amount` are independent. Implementations SHOULD keep the allowance close to the expected per-request ceiling and re-approve as needed, rather than approving a large standing balance, to limit exposure if a facilitator or the escrow contract is ever compromised.
+4. **Nonce exhaustion / griefing**: because settlement is optional (zero-settlement need not touch the chain), a malicious client cannot force facilitator gas spend by signing many unused authorizations; only the facilitator's own `/settle` calls cost gas, and it only calls them for its own resource server's confirmed usage.
+5. **Smart account composition**: see [Composition with Smart Account Spending Policies](#composition-with-smart-account-spending-policies) — this is an additive, optional safeguard and its absence does not weaken the guarantees this spec makes about a single authorization.

-# Design note: `POST /settle`
-
-> **Status: implemented in the same PR as this note.** #126 asks for the four
-> decisions below to be made in the open before settlement code is written,
-> because this is the only facilitator route that moves money and a mistake in
-> it is not recoverable by redeploying. The note is therefore the first thing
-> to read and the thing to argue with: if a decision here is wrong, the code
-> that follows it is wrong, and changing it is cheap now and expensive later.
-
-## Scope
-
-Per the RFP, settlement is not reimplemented:
-
-> "Respondents should build on the Apache-2.0 `@x402/stellar` package rather
-> than reimplement verify and settle. Settlement on Stellar is largely solved;
-> the novel work is discovery, the agent facing interface, the `upto` scheme
-> upstream, and conformance that holds as the spec moves."
-
-So the cryptography, simulation checks, auth-entry validation and submission
-all come from `ExactStellarScheme` in `@x402/stellar/exact/facilitator`,
-registered on an `x402Facilitator` from `@x402/core/facilitator`. What this
-route owns is the surface around that call: the wire contract, key custody,
-idempotency, replay, and failure mapping. That is where the four questions
-below live.
-
-The route sits alongside the other facilitator routes
-(`src/routes/facilitator.ts`, introduced by #124) and reuses whatever
-`x402Facilitator` instance #125 lands for `/verify`, rather than constructing a
-second one.
-
-### Wire contract
-
-`HTTPFacilitatorClient` in `@x402/core` posts to `{url}/settle` with
-
-```json
-{ "x402Version": 2, "paymentPayload": { … }, "paymentRequirements": { … } }
-```
-
-and parses the response against `settleResponseSchema`:
-
-```ts
-type SettleResponse = {
-  success: boolean
-  errorReason?: string
-  errorMessage?: string
-  payer?: string
-  transaction: string   // tx hash
-  network: Network
-  amount?: string
-  extensions?: Record<string, unknown>
-}
-```
-
-The client treats a non-2xx response whose body contains `success` as a
-`SettleError` and anything else as a transport error. So: **a payment that
-fails is a `200` with `success: false` and a non-null `errorReason`**, not a
-4xx. 4xx/5xx is reserved for a request we could not parse or a fault that is
-ours, and even then the body keeps the `SettleResponse` shape so an unmodified
-canonical client can still read it.
-
-`payload: { transaction }` — the spec's base64 XDR envelope — is accepted
-verbatim; the payload is passed to the SDK untouched.
-
----
-
-## 1. What keys does this hold?
-
-**Not the payer's.** In `exact` the payer authorises with a signed Soroban auth
-entry carried inside `paymentPayload.payload.transaction`. The facilitator
-never sees a payer secret and never holds user funds: the token contract moves
-value payer → `payTo` directly, and `ExactStellarScheme` refuses a payload
-where a facilitator address is a participant in the transfer (its
-`validateSimulationEvents` check). Non-custodial is a property of the flow, not
-a promise in a README.
-
-Two keys do exist, and both exist only to pay fees and supply a sequence
-number:
-
-| Key | Role | Can it move user funds? |
-|---|---|---|
-| Settlement signer(s) — `FacilitatorStellarSigner[]` | Transaction source; signs and submits the envelope carrying the payer's auth entry | No. It authorises nothing in the token contract; the payer's auth entry does. |
-| Fee-bump signer — `feeBumpSigner` (optional) | Fee source of a `FeeBumpTransaction` wrapping the inner transaction | No. It pays fees only, and decouples fee payment from sequence-number management. |
-
-This is the pattern the issue points at: Veil's sponsoring fee-payer, which
-pays network fees for accounts whose funds it cannot touch. The accounts hold
-XLM for fees and nothing else — no USDC, no user balances — so the blast radius
-of a compromised settlement key is "someone burns our fee budget", not
-"someone drains a payer".
-
-**Where the secret lives.** `FACILITATOR_SECRET_KEY_TESTNET` /
-`FACILITATOR_SECRET_KEY_MAINNET` (with the unsuffixed `FACILITATOR_SECRET_KEY`
-applying to testnet), resolved through `getNetworkConfig(network).facilitator`
-— the same place `/supported` and `/verify` read their keys, so there is one
-answer to "which account settles on this network". Read once at plugin init like every other secret
-in this repo, held in process memory, never written to Postgres, never logged,
-and never returned by any route. `/supported` continues to advertise only the
-public addresses, which #124 already does via `FACILITATOR_SIGNER_ADDRESSES`.
-With no secrets configured the route registers but answers every request with
-`success: false` and a reason saying settlement is not configured, so a
-misconfigured deploy fails loudly and safely instead of half-working.
-
-Fee ceiling stays configurable rather than hard-wired, per the RFP:
-`maxTransactionFeeStroops` from `FACILITATOR_FEE_STROOPS_<NETWORK>` (default
-50,000), so a self-hoster can change it.
-
-## 2. Idempotency
-
-**The key is derived from the payload, never generated by us:** the hash of the
-inner transaction, `new Transaction(payload.transaction, passphrase).hash()`,
-hex-encoded, scoped by network.
-
-Three properties earn it the job. It is deterministic — a retry of the same
-payload produces the same key without the caller sending an idempotency header.
-It is the identifier the network itself will assign, so the key we store before
-submitting is the same string we return in `SettleResponse.transaction`
-afterwards. And it is network-scoped by construction, since the passphrase is
-mixed into the hash — the same envelope on testnet and pubnet cannot collide.
-
-A fee bump does not disturb this: the fee-bump envelope hashes differently, but
-the *inner* hash is unchanged, and the inner hash is what the ledger records
-for the payment. We key on the inner hash and store the outer one for support.
-
-**The record is written before submission, not after** — the same lesson as
-`packages/bills` in the Veil repo, where the reference is minted and stored
-before dispatch precisely so a timeout is recoverable:
-
-```prisma
-model SettlementAttempt {
-  id           String   @id @default(cuid())
-  network      String   // stellar:pubnet | stellar:testnet
-  txHash       String   // inner transaction hash — the idempotency key
-  state        String   // submitting | settled | failed
-  payer        String?
-  asset        String?
-  amount       String?
-  payTo        String?
-  errorReason  String?
-  errorMessage String?
-  response     Json?    // the SettleResponse we returned, replayed verbatim
-  createdAt    DateTime @default(now())
-  updatedAt    DateTime @updatedAt
-
-  @@unique([network, txHash])
-}
-```
-
-The unique constraint is the lock, not an advisory one held in application
-memory: two concurrent settles for the same payload race to `INSERT`, exactly
-one wins, and the loser takes the "already seen" path below. That holds across
-replicas, which an in-process mutex would not.
-
-Sequence: insert `submitting` → call `facilitator.settle(...)` → update to
-`settled`/`failed` with the response. If the process dies between the insert
-and the update, the row is left in `submitting`, which is the honest state: we
-do not know whether the network took it. Recovery reads the transaction by hash
-from RPC rather than resubmitting.
-
-## 3. Replay across requests
-
-`/verify` stays side-effect free by design, so it cannot be what burns a
-payload. `/settle` is.
-
-A payload is consumed the moment its `SettlementAttempt` row exists. On a
-second settle for the same key:
-
-- `settled` → return the stored `SettleResponse` verbatim, `success: true`, same
-  transaction hash. The retrying resource server gets the answer it lost, and
-  the payer is charged once.
-- `failed` → return the stored failure verbatim, including its `errorReason`. A
-  failed settle is not retried under the same key; the payer must re-authorise.
-- `submitting` → do not resubmit. Look the hash up on-chain, finalise the row
-  from what the ledger says, and answer from that. If the ledger does not know
-  it yet, return `success: false` with a reason that says the settlement is
-  still in flight, which is a true statement rather than a guess.
-
-The chain would catch a genuine double-spend anyway — the auth entry carries a
-nonce and `signatureExpirationLedger`, so a second submission of the same
-envelope fails at the network. The database is what makes the *response*
-deterministic and cheap instead of leaning on a failed submission to produce
-it. Validity stays bounded by `signatureExpirationLedger` (~12 ledgers / 60s
-from `maxTimeoutSeconds`), which the SDK enforces during verification.
-
-## 4. Failure semantics
-
-The rule is: **match the reference facilitator, do not invent our own vocabulary.**
-`ExactStellarScheme` already emits a fixed set of reasons, and we return them
-unaltered rather than rewriting them into something friendlier:
-
-`invalid_exact_stellar_payload_malformed`,
-`settle_exact_stellar_signer_selection_failed`,
-`settle_exact_stellar_transaction_signing_failed`,
-`settle_exact_stellar_fee_bump_signing_failed`,
-`settle_exact_stellar_transaction_submission_failed`,
-`settle_exact_stellar_transaction_failed`,
-`unexpected_settle_error`.
-
-| Situation | HTTP | `success` | `errorReason` |
-|---|---|---|---|
-| Settled and final | 200 | `true` | — |
-| Rejected on-chain | 200 | `false` | whatever the SDK returned |
-| Submitted, not yet final (SDK polling exhausted) | 200 | `false` | the SDK's reason; the row stays `submitting` and a retry answers from the ledger |
-| RPC unreachable / our own fault | 200 | `false` | `unexpected_settle_error`, with the detail in `errorMessage` |
-| Body not parseable as a settle request | 400 | `false` | `invalid_exact_stellar_payload_malformed` |
-| Settlement keys not configured | 200 | `false` | `unexpected_settle_error` |
-
-**Every rejection carries a non-null `errorReason`** — an RFP hard criterion,
-so that an agent can branch on failure instead of parsing prose. That is
-asserted directly in the tests rather than left as a claim.
-
-`errorMessage` may carry detail for a human; it never carries key material,
-XDR, or anything about other payers.
-
-## What the implementation does
-
-- `POST /settle` in `src/routes/facilitator.ts`, delegating to
-  `ExactStellarScheme` through `x402Facilitator` — no verification or
-  settlement logic of our own
-- `SettlementAttempt` in `prisma/schema.prisma`, written before submission,
-  with `@@unique([network, txHash])` as the lock
-- `src/x402/facilitator.ts` holds configuration and keys only, and returns
-  null rather than a half-built facilitator when no signing key is configured
-- Both networks from the existing per-network config — no testnet-only path
-- Tests in `src/__tests__/facilitatorSettle.test.ts`: the same payload settled
-  twice submits once and replays the first answer; the record exists before
-  submission (asserted from inside the settle spy); an in-flight record
-  resolves from the ledger rather than resubmitting; a `C…` contract-account
-  payload takes the same path as a `G…` one; both networks; every failure
-  branch returns a non-null `errorReason`; malformed payload → 400 still in
-  the settle shape
-
-Still outstanding, and not something code can supply: **a published settled
-transaction hash per network**, per the RFP's acceptance criteria. That needs
-funded keys on both networks, which is a deployment step rather than a change
-to this PR.
-
-## The four decisions, restated for review
-
-1. **Key custody** — settlement signer plus optional fee-bump signer, env-held,
-   fee-only balances, no secret ever persisted. Objections?
-2. **Idempotency key = inner transaction hash**, rather than a caller-supplied
-   header or a digest of the whole request body.
-3. **Terminal failures are not retried under the same key** — a `failed` row
-   replays its failure instead of re-submitting. The alternative (let a retry
-   try again) trades idempotency for a second chance; I do not think that is
-   the trade to make here.
-4. **`submitting` rows resolve from the ledger, never by resubmission.**
-
-If any of those four is wrong, say so and the implementation follows the
-correction — these are the decisions the issue asked to have in the open, not
-settled facts.
+# Design note: `POST /settle`
+
+> **Status: implemented in the same PR as this note.** #126 asks for the four
+> decisions below to be made in the open before settlement code is written,
+> because this is the only facilitator route that moves money and a mistake in
+> it is not recoverable by redeploying. The note is therefore the first thing
+> to read and the thing to argue with: if a decision here is wrong, the code
+> that follows it is wrong, and changing it is cheap now and expensive later.
+
+## Scope
+
+Per the RFP, settlement is not reimplemented:
+
+> "Respondents should build on the Apache-2.0 `@x402/stellar` package rather
+> than reimplement verify and settle. Settlement on Stellar is largely solved;
+> the novel work is discovery, the agent facing interface, the `upto` scheme
+> upstream, and conformance that holds as the spec moves."
+
+So the cryptography, simulation checks, auth-entry validation and submission
+all come from `ExactStellarScheme` in `@x402/stellar/exact/facilitator`,
+registered on an `x402Facilitator` from `@x402/core/facilitator`. What this
+route owns is the surface around that call: the wire contract, key custody,
+idempotency, replay, and failure mapping. That is where the four questions
+below live.
+
+The route sits alongside the other facilitator routes
+(`src/routes/facilitator.ts`, introduced by #124) and reuses whatever
+`x402Facilitator` instance #125 lands for `/verify`, rather than constructing a
+second one.
+
+### Wire contract
+
+`HTTPFacilitatorClient` in `@x402/core` posts to `{url}/settle` with
+
+```json
+{ "x402Version": 2, "paymentPayload": { … }, "paymentRequirements": { … } }
+```
+
+and parses the response against `settleResponseSchema`:
+
+```ts
+type SettleResponse = {
+  success: boolean
+  errorReason?: string
+  errorMessage?: string
+  payer?: string
+  transaction: string   // tx hash
+  network: Network
+  amount?: string
+  extensions?: Record<string, unknown>
+}
+```
+
+The client treats a non-2xx response whose body contains `success` as a
+`SettleError` and anything else as a transport error. So: **a payment that
+fails is a `200` with `success: false` and a non-null `errorReason`**, not a
+4xx. 4xx/5xx is reserved for a request we could not parse or a fault that is
+ours, and even then the body keeps the `SettleResponse` shape so an unmodified
+canonical client can still read it.
+
+`payload: { transaction }` — the spec's base64 XDR envelope — is accepted
+verbatim; the payload is passed to the SDK untouched.
+
+---
+
+## 1. What keys does this hold?
+
+**Not the payer's.** In `exact` the payer authorises with a signed Soroban auth
+entry carried inside `paymentPayload.payload.transaction`. The facilitator
+never sees a payer secret and never holds user funds: the token contract moves
+value payer → `payTo` directly, and `ExactStellarScheme` refuses a payload
+where a facilitator address is a participant in the transfer (its
+`validateSimulationEvents` check). Non-custodial is a property of the flow, not
+a promise in a README.
+
+Two keys do exist, and both exist only to pay fees and supply a sequence
+number:
+
+| Key | Role | Can it move user funds? |
+|---|---|---|
+| Settlement signer(s) — `FacilitatorStellarSigner[]` | Transaction source; signs and submits the envelope carrying the payer's auth entry | No. It authorises nothing in the token contract; the payer's auth entry does. |
+| Fee-bump signer — `feeBumpSigner` (optional) | Fee source of a `FeeBumpTransaction` wrapping the inner transaction | No. It pays fees only, and decouples fee payment from sequence-number management. |
+
+This is the pattern the issue points at: Veil's sponsoring fee-payer, which
+pays network fees for accounts whose funds it cannot touch. The accounts hold
+XLM for fees and nothing else — no USDC, no user balances — so the blast radius
+of a compromised settlement key is "someone burns our fee budget", not
+"someone drains a payer".
+
+**Where the secret lives.** `FACILITATOR_SECRET_KEY_TESTNET` /
+`FACILITATOR_SECRET_KEY_MAINNET` (with the unsuffixed `FACILITATOR_SECRET_KEY`
+applying to testnet), resolved through `getNetworkConfig(network).facilitator`
+— the same place `/supported` and `/verify` read their keys, so there is one
+answer to "which account settles on this network". Read once at plugin init like every other secret
+in this repo, held in process memory, never written to Postgres, never logged,
+and never returned by any route. `/supported` continues to advertise only the
+public addresses, which #124 already does via `FACILITATOR_SIGNER_ADDRESSES`.
+With no secrets configured the route registers but answers every request with
+`success: false` and a reason saying settlement is not configured, so a
+misconfigured deploy fails loudly and safely instead of half-working.
+
+Fee ceiling stays configurable rather than hard-wired, per the RFP:
+`maxTransactionFeeStroops` from `FACILITATOR_FEE_STROOPS_<NETWORK>` (default
+50,000), so a self-hoster can change it.
+
+## 2. Idempotency
+
+**The key is derived from the payload, never generated by us:** the hash of the
+inner transaction, `new Transaction(payload.transaction, passphrase).hash()`,
+hex-encoded, scoped by network.
+
+Three properties earn it the job. It is deterministic — a retry of the same
+payload produces the same key without the caller sending an idempotency header.
+It is the identifier the network itself will assign, so the key we store before
+submitting is the same string we return in `SettleResponse.transaction`
+afterwards. And it is network-scoped by construction, since the passphrase is
+mixed into the hash — the same envelope on testnet and pubnet cannot collide.
+
+A fee bump does not disturb this: the fee-bump envelope hashes differently, but
+the *inner* hash is unchanged, and the inner hash is what the ledger records
+for the payment. We key on the inner hash and store the outer one for support.
+
+**The record is written before submission, not after** — the same lesson as
+`packages/bills` in the Veil repo, where the reference is minted and stored
+before dispatch precisely so a timeout is recoverable:
+
+```prisma
+model SettlementAttempt {
+  id           String   @id @default(cuid())
+  network      String   // stellar:pubnet | stellar:testnet
+  txHash       String   // inner transaction hash — the idempotency key
+  state        String   // submitting | settled | failed
+  payer        String?
+  asset        String?
+  amount       String?
+  payTo        String?
+  errorReason  String?
+  errorMessage String?
+  response     Json?    // the SettleResponse we returned, replayed verbatim
+  createdAt    DateTime @default(now())
+  updatedAt    DateTime @updatedAt
+
+  @@unique([network, txHash])
+}
+```
+
+The unique constraint is the lock, not an advisory one held in application
+memory: two concurrent settles for the same payload race to `INSERT`, exactly
+one wins, and the loser takes the "already seen" path below. That holds across
+replicas, which an in-process mutex would not.
+
+Sequence: insert `submitting` → call `facilitator.settle(...)` → update to
+`settled`/`failed` with the response. If the process dies between the insert
+and the update, the row is left in `submitting`, which is the honest state: we
+do not know whether the network took it. Recovery reads the transaction by hash
+from RPC rather than resubmitting.
+
+## 3. Replay across requests
+
+`/verify` stays side-effect free by design, so it cannot be what burns a
+payload. `/settle` is.
+
+A payload is consumed the moment its `SettlementAttempt` row exists. On a
+second settle for the same key:
+
+- `settled` → return the stored `SettleResponse` verbatim, `success: true`, same
+  transaction hash. The retrying resource server gets the answer it lost, and
+  the payer is charged once.
+- `failed` → return the stored failure verbatim, including its `errorReason`. A

-# Bazaar MCP Server Example
-
-This directory contains two runnable examples that expose the Lens Bazaar
-catalog as a [Model Context Protocol](https://modelcontextprotocol.io)
-(MCP) server:
-
-| Command | File | What it does |
-|---|---|---|
-| `npm run mcp:server` | `run.ts` | Starts the Bazaar MCP server on stdio. It signs x402 payment challenges with two Stellar secret keys — one for testnet, one for mainnet — and forwards paid API calls to Bazaar resources, handling the 402 → sign → 200 loop automatically. |
-| `npm run mcp:agent` | `agent.ts` | Starts a mock Bazaar API on `http://localhost:3000`, connects an MCP client to the server, lists the available tools, calls `bazaar_search`, then makes a `paid_call` to the discovered resource. End-to-end demonstration of an agent discovering and paying for a resource. |
-
-## ⚠️ Warning: this signs with a real mainnet key
-
-`run.ts` requires `MCP_AGENT_SECRET_KEY_MAINNET` and builds a signer for
-`stellar:pubnet` (mainnet). Any payment the server signs spends **real XLM**
-from the account that key controls — there is no sandbox, no dry-run, and no
-confirmation prompt.
-
-**Do not run these commands with a funded mainnet key until you have read the
-"Safe way to try it first" section below.**
-
-The MCP server can spend up to `MCP_MAX_PAYMENT_PRICE` (default `$1.00`) per
-paid call from the mainnet account.
-
-## Configuration
-
-| Variable | Required | Description |
-|---|---|---|
-| `MCP_AGENT_SECRET_KEY_TESTNET` | Yes | Stellar secret key used to sign payments on `stellar:testnet` |
-| `MCP_AGENT_SECRET_KEY_MAINNET` | Yes | Stellar secret key used to sign payments on `stellar:pubnet` (mainnet) — **real money** |
-| `MCP_MAX_PAYMENT_PRICE` | No | Maximum price the server will pay per request (default: `$1.00`) |
-
-Both keys are required: `run.ts` exits with an error if either is unset.
-
-The server talks to two Stellar networks:
-- `stellar:testnet` — safe, friendbot-funded play money
-- `stellar:pubnet` — mainnet, real XLM
-
-## Safe way to try it first
-
-Never test with a funded mainnet key. Instead:
-
-1. Create a fresh testnet account and fund it via [friendbot](https://docs.stellar.org/create-account) so it holds testnet XLM. Set `MCP_AGENT_SECRET_KEY_TESTNET` to that testnet secret.
-2. For `MCP_AGENT_SECRET_KEY_MAINNET`, use a brand-new mainnet account with **zero XLM** (or any account you can afford to lose). A payment attempt against an unfunded account fails deterministically with `ERR_INSUFFICIENT_BALANCE` instead of spending money.
-3. Leave `MCP_MAX_PAYMENT_PRICE` at its default `$1.00`, or lower it.
-
-Only once you have confirmed the flow behaves as expected on testnet should you consider pointing `MCP_AGENT_SECRET_KEY_MAINNET` at a funded mainnet account — and only with an amount you are prepared to spend.
-
-Never log, echo, print, or commit a real secret key. This README shows env var names only; it never shows a key value.
-
-## Worked example: connect a client and call each tool
-
-Prerequisites:
-
-- Node.js installed
-- Dependencies installed at the repo root (`npm install`)
-- The two secret-key env vars set (see "Safe way to try it first" above)
-
-Run the server in one terminal:
-
-```bash
-export MCP_AGENT_SECRET_KEY_TESTNET=<your-testnet-secret-key>
-export MCP_AGENT_SECRET_KEY_MAINNET=<your-empty-mainnet-secret-key>
-npm run mcp:server
-```
-
-The server starts on stdio and logs:
-
-```
-[mcp-server] Starting Bazaar MCP server on stdio...
-[mcp-server] Agent configured for stellar:testnet and stellar:pubnet
-```
-
-In another terminal, run the agent example, which connects an MCP client,
-lists the tools, and calls both of them:
-
-```bash
-npm run mcp:agent
-```
-
-Expected output (shortened for readability here; the actual run prints full
-JSON):
-
-```
-[mock-server] Started mock Bazaar API on http://localhost:3000
-[agent] Starting MCP server child process...
-[agent] Connected to Bazaar MCP server.
-[agent] Available tools: bazaar_search, paid_call
-
-[agent] 1. Discovering resources at http://localhost:3000...
-[agent] Executing tool: bazaar_search
-[agent] Search result: {"resources":[{"name":"Mock Price Feed",...}]}
-
-[agent] 2. Making a paid call to http://localhost:3000/api/v1/price...
-[agent] Executing tool: paid_call
-[agent] The MCP server will handle the 402 loop automatically...
-[agent] Paid call succeeded! Retrieved data:
-{"asset":"XLM","price":0.15,"timestamp":"..."}
-
-[agent] End to end demonstration complete.
-```
-
-### What each tool does
-
-- `bazaar_search` — searches a Bazaar node's discovery endpoint. Takes `url`
-  (base URL of the Bazaar API) and an optional `query`. Returns the catalog of
-  discoverable resources, or a structured error such as `ERR_NO_RESULTS` or
-  `ERR_SERVICE_UNREACHABLE`.
-- `paid_call` — makes a paid API call to a Bazaar resource, handling the x402
-  402 payment loop automatically. Takes `url` (full URL of the resource) and an
-  optional `method` (default `GET`). Returns the resource body, or a structured
-  error such as `ERR_PAYMENT_REJECTED`, `ERR_INSUFFICIENT_BALANCE`,
-  `ERR_MISSING_TRUSTLINE`, `ERR_EXPIRED_AUTHORISATION`, or
-  `ERR_SERVICE_UNREACHABLE`.
-
-### Standalone client example
-
-You can also connect your own MCP client to the server. This TypeScript
-example connects via stdio, lists tools, and calls both tools:
-
-```typescript
-import { Client } from '@modelcontextprotocol/sdk/client/index.js';
-import { StdioClientTransport } from '@modelcontextprotocol/sdk/client/stdio.js';
-
-async function main() {
-  const transport = new StdioClientTransport({
-    command: process.platform === 'win32' ? 'npx.cmd' : 'npx',
-    args: ['tsx', 'examples/mcp-server/run.ts'],
-  });
-
-  const client = new Client(
-    { name: 'bazaar-client-example', version: '1.0.0' },
-    { capabilities: {} },
-  );
-
-  await client.connect(transport);
-
-  const tools = await client.listTools();
-  console.log('Available tools:', tools.tools.map((t) => t.name).join(', '));
-
-  // 1. Search for resources
-  const search = await client.callTool({
-    name: 'bazaar_search',
-    arguments: { url: 'http://localhost:3000', query: 'XLM price' },
-  });
-  console.log('Search:', search.content[0].text);
-
-  // 2. Make a paid call to the discovered resource
-  const paid = await client.callTool({
-    name: 'paid_call',
-    arguments: { url: 'http://localhost:3000/api/v1/price' },
-  });
-  console.log('Paid call:', paid.content[0].text);
-
-  await client.close();
-}
-
-main().catch((err) => {
-  console.error(err);
-  process.exit(1);
-});
-```
-
-Run it with `npx tsx <file>` from the repo root, with the secret-key env vars
-set. The server process is spawned automatically by the transport.
-
-## Error codes
-
-Paid-call failures return deterministic, machine-readable codes (see
-`src/mcp/codes.ts`):
-
-| Code | Meaning |
-|---|---|
-| `ERR_PAYMENT_REJECTED` | Payment was required but rejected or failed |
-| `ERR_INSUFFICIENT_BALANCE` | The signing account lacks the balance to pay |
-| `ERR_MISSING_TRUSTLINE` | Missing trustline for the required asset |
-| `ERR_EXPIRED_AUTHORISATION` | The transaction signature expired before submission |
-| `ERR_SERVICE_UNREACHABLE` | The Bazaar service could not be reached |
-| `ERR_NO_RESULTS` | The search returned no resources |
-| `ERR_BAD_REQUEST` | The request failed with a non-402 error status |
-| `ERR_INTERNAL_FAILURE` | An unknown error occurred during the paid call |
-
-An agent is the least able caller to notice a wrong answer: the server
-prefers returning a structured error over guessing a best-effort result, so
-always check `isError` before acting on a tool response.

+| `ERR_NO_RESULTS` | The search returned no resources |
+| `ERR_BAD_REQUEST` | The request failed with a non-402 error status |
+| `ERR_INTERNAL_FAILURE` | An unknown error occurred during the paid call |
+
+An agent is the least able caller to notice a wrong answer: the server
+prefers returning a structured error over guessing a best-effort result, so
+always check `isError` before acting on a tool response.

-//! Lens SEP-40 price feed contract.
-//!
-//! SEP-40 ("Oracle Consumer Interface") standardises how a Soroban contract
-//! READS a price feed. It deliberately says nothing about how a provider writes
-//! one ("The exact mechanism of data reporting mechanism utilized by an oracle
-//! is out of scope of this SEP" — SEP-40 § Design Rationale / Data Reporting).
-//! So this contract has two halves:
-//!
-//! 1. the `PriceFeedTrait` surface from the spec — `base`, `assets`, `decimals`,
-//!    `resolution`, `price`, `prices`, `lastprice` — exactly as declared, so any
-//!    SEP-40 consumer can read a Lens price without an adapter contract;
-//! 2. a provider-side `report` write, authenticated by the Lens publisher key,
-//!    which is the only way data gets in.
-//!
-//! Prices are stored as `i128` scaled by `decimals()`: the real value is
-//! `price / 10^decimals` (SEP-40 § Design Rationale). Timestamps are unix
-//! seconds trimmed to `resolution()`, so consumers can compare them against the
-//! current ledger time to judge staleness — and Lens trims them on the way in,
-//! which `report` then re-checks, so a mis-scaled write cannot land.
-//!
-//! Provenance: every report carries the list of venues behind the number
-//! (`SDEX`, `AMM`, `aquarius_amm`, …). The source count is derived from that
-//! list rather than passed in, so the contract can never record a price that
-//! claims more sources than it can name.

+//! Lens SEP-40 price feed contract.
+//!
+//! SEP-40 ("Oracle Consumer Interface") standardises how a Soroban contract
+//! READS a price feed. It deliberately says nothing about how a provider writes
+//! one ("The exact mechanism of data reporting mechanism utilized by an oracle
+//! is out of scope of this SEP" — SEP-40 § Design Rationale / Data Reporting).
+//! So this contract has two halves:
+//!
+//! 1. the `PriceFeedTrait` surface from the spec — `base`, `assets`, `decimals`,
+//!    `resolution`, `price`, `prices`, `lastprice` — exactly as declared, so any
+//!    SEP-40 consumer can read a Lens price without an adapter contract;
+//! 2. a provider-side `report` write, authenticated by the Lens publisher key,
+//!    which is the only way data gets in.
+//!
+//! Prices are stored as `i128` scaled by `decimals()`: the real value is
+//! `price / 10^decimals` (SEP-40 § Design Rationale). Timestamps are unix
+//! seconds trimmed to `resolution()`, so consumers can compare them against the
+//! current ledger time to judge staleness — and Lens trims them on the way in,
+//! which `report` then re-checks, so a mis-scaled write cannot land.
+//!
+//! Provenance: every report carries the list of venues behind the number
+//! (`SDEX`, `AMM`, `aquarius_amm`, …). The source count is derived from that
+//! list rather than passed in, so the contract can never record a price that
+//! claims more sources than it can name.

- * the older version plus the author's additions. Merging it silently removes

- *
- * Observed on Lens #480 (19 cases: the Zod argument suite and the upstream

- * both typechecked, and in both cases the loss was only visible by counting
- * `it(` on each side.
- *
- * What this does NOT do: run the tests, or judge whether a removal is correct.
- * Removing a test is sometimes exactly right — the feature went away, the case
- * was a duplicate, the assertion was wrong. It reports which cases disappear so
- * the decision is made deliberately rather than by accident. Say so in the PR
- * and apply the override label.
- *
- * Compares the base against the MERGE RESULT, not against the branch tip.
- * Comparing against the tip over-reports wildly — a branch 47 commits behind

+ * This exists because it happened twice in one day and git said nothing both
+ * times. A branch opened before several PRs landed replaces a whole test file
+ * rather than merging it, so there is no textual conflict — the file is simply
+ * the older version plus the author's additions. Merging it silently removes
+ * every case added in between.
+ *
+ * Observed on Lens #480 (19 cases: the Zod argument suite and the upstream
+ * deadline suite) and again on #492 (the same 19). Both reported "mergeable",
+ * both typechecked, and in both cases the loss was only visible by counting
+ * `it(` on each side.
+ *
+ * What this does NOT do: run the tests, or judge whether a removal is correct.
+ * Removing a test is sometimes exactly right — the feature went away, the case
+ * was a duplicate, the assertion was wrong. It reports which cases disappear so
+ * the decision is made deliberately rather than by accident. Say so in the PR
+ * and apply the override label.
+ *
+ * Compares the base against the MERGE RESULT, not against the branch tip.
+ * Comparing against the tip over-reports wildly — a branch 47 commits behind
+ * is "missing" every case added since it forked, whether or not merging would
+ * drop them. What matters is the tree that would actually land.
+ *
+ *   node scripts/check-dropped-tests.mjs <base-ref> [head-ref]
+ *
+ * Exits 1 when cases are missing from the merge result, 0 otherwise.

- * The invariant, rather than a sample of it.
- *
- * The point of #514 is that an admin endpoint is protected by *where it lives*,
- * so the test that matters is over every route the admin plugins register, not
- * over the three a test author happened to think of. `onRoute` sees each route
- * as it is registered, including its config, which is exactly what the guard
- * reads at request time.
- *
- * It also catches the inverse mistake: a route under /admin that still declares
- * `public: true`. That combination used to be how admin routes opted out of the
- * API-key hook, and five of them were still written that way — harmless while
- * the per-handler `isAdminAuthorized` checks remain, and a hole the moment
- * someone removes them on the strength of "the hook handles it now".

+ * as it is registered, including its config, which is exactly what the guard

+ *
+ * It also catches the inverse mistake: a route under /admin that still declares

-/**
- * Backpressure for slow websocket consumers.
- *
- * The bug this covers: `send()` neither blocks nor throws when a peer stops
- * reading, it queues. With nothing inspecting `bufferedAmount`, one subscriber
- * on a bad mobile connection could grow the process until it was OOM-killed —
- * taking every other subscriber with it. The assertions below drive a socket
- * that accepts data and never flushes it, and check that what it holds stays
- * bounded, that it eventually gets dropped, and that nothing it does affects
- * any other client.
- *
- * Metrics are read from the real registry (no mock) because the
- * counts themselves are the point: a truncated feed that is not counted is
- * indistinguishable from a healthy one.
- *
- * The thresholds are set in the environment *before* the module is imported —
- * they are resolved once at import, because they are read on the price-update
- * path. They are deliberately tiny here so a handful of updates reaches them;
- * `resolveBackpressureLimits` is unit-tested separately against the shipped
- * defaults.

+/**
+ * Backpressure for slow websocket consumers.
+ *
+ * The bug this covers: `send()` neither blocks nor throws when a peer stops
+ * reading, it queues. With nothing inspecting `bufferedAmount`, one subscriber
+ * on a bad mobile connection could grow the process until it was OOM-killed —
+ * taking every other subscriber with it. The assertions below drive a socket
+ * that accepts data and never flushes it, and check that what it holds stays
+ * bounded, that it eventually gets dropped, and that nothing it does affects
+ * any other client.
+ *
+ * Metrics are read from the real registry (no mock) because the
+ * counts themselves are the point: a truncated feed that is not counted is
+ * indistinguishable from a healthy one.
+ *
+ * The thresholds are set in the environment *before* the module is imported —
+ * they are resolved once at import, because they are read on the price-update
+ * path. They are deliberately tiny here so a handful of updates reaches them;
+ * `resolveBackpressureLimits` is unit-tested separately against the shipped
+ * defaults.

-The depth fixture uses reserves A=100 and B=200 with a 30 bp fee. Spot is
-`200/100 = 2`. At step size 0.1 the ask sells 10 A; after fees its input is
-9.97, so its displayed price is `(200×9.97/(100+9.97))/10`. The bid inputs 20
-B (19.94 after fees), receives `100×19.94/(200+19.94)` A, and displays the
-price as input B divided by output A. The pricing fixture test asserts these

-/**
- * Unit tests for the Phoenix AMM venue adapter (#210).
- *
- * Covered:
- * - calcSpotPrice: the reserve→price derivation, including zero reserves
- * - parsePoolInfo: the shapes `query_pool_info` returns, and refusal to guess
- * - sacContractId / poolMatchesPair: watched classic asset → Soroban token
- * - derivePhoenixPricePoints: orientation, source labelling, empty pools
- * - discovery: factory enumeration, TTL cache, stale-on-failure, single-flight
- * - degrade: an unreachable RPC silences Phoenix and throws nothing
- * - the network a price was read from is the network it is written with
- *
- * The contract ids and reserve amounts in the fixtures are the values read live
- * from mainnet (ledger 64,991,171) from the factory
- * CB4SVAWJA6TSRNOJZ7W2AWFW46D5VR4ZMFZKDIKXEINZCZEGZCJZCKMI, so these tests pin
- * the adapter to Phoenix's real deployment rather than to a plausible shape.

+ * - sacContractId / poolMatchesPair: watched classic asset → Soroban token

+ * - discovery: factory enumeration, TTL cache, stale-on-failure, single-flight
+ * - degrade: an unreachable RPC silences Phoenix and throws nothing
+ * - the network a price was read from is the network it is written with
+ *
+ * The contract ids and reserve amounts in the fixtures are the values read live

-// ── In-process API-key lookup cache (Issue #495) ────────────────────────────
-//
-// Authentication runs in an `onRequest` hook, so without a cache every request
-// — including ones served entirely from the Redis price cache — pays a Postgres
-// round-trip before any work begins, and the API cannot even accept traffic
-// when the shared connection pool is slow or exhausted. We cache the lookup,
-// keyed by the key hash, for a short TTL (`config.cache.apiKeyTtl` seconds).
-//
-// Correctness of the sharp edges:
-//   • Revocation. The revoke route (admin.ts) calls `invalidateApiKey(hash)`,
-//     so a key revoked on THIS instance stops working immediately. A key
-//     revoked on another instance keeps working here until its cache entry
-//     expires — a worst case of exactly `config.cache.apiKeyTtl` seconds. The
-//     test "a revoked key stops working" pins this contract.
-//   • Expiry. We store the key's own `expiresAt` and re-check it on every hit
-//     (see `evaluate`), so the TTL never extends a key past its expiry.
-//   • Negative lookups are cached too. Otherwise an invalid key is a free way
-//     to make the API hit Postgres as fast as a client can send requests.
-//   • The cache is size-bounded (`MAX_CACHE_ENTRIES`) so a flood of distinct
-//     invalid keys cannot grow the negative cache without limit; the oldest
-//     entry is evicted once the cap is reached.

+// ── In-process API-key lookup cache (Issue #495) ────────────────────────────
+//
+// Authentication runs in an `onRequest` hook, so without a cache every request
+// — including ones served entirely from the Redis price cache — pays a Postgres
+// round-trip before any work begins, and the API cannot even accept traffic
+// when the shared connection pool is slow or exhausted. We cache the lookup,
+// keyed by the key hash, for a short TTL (`config.cache.apiKeyTtl` seconds).
+//
+// Correctness of the sharp edges:
+//   • Revocation. The revoke route (admin.ts) calls `invalidateApiKey(hash)`,
+//     so a key revoked on THIS instance stops working immediately. A key
+//     revoked on another instance keeps working here until its cache entry
+//     expires — a worst case of exactly `config.cache.apiKeyTtl` seconds. The
+//     test "a revoked key stops working" pins this contract.
+//   • Expiry. We store the key's own `expiresAt` and re-check it on every hit
+//     (see `evaluate`), so the TTL never extends a key past its expiry.
+//   • Negative lookups are cached too. Otherwise an invalid key is a free way
+//     to make the API hit Postgres as fast as a client can send requests.
+//   • The cache is size-bounded (`MAX_CACHE_ENTRIES`) so a flood of distinct
+//     invalid keys cannot grow the negative cache without limit; the oldest
+//     entry is evicted once the cap is reached.

-/**
- * Shared JSON Schema objects for REST response validation.
- *
- * These schemas serve two purposes:
- *   1. They are attached to routes via `{ schema: { response: { 200: ... } } }`,
- *      which lets Fastify auto-generate a correct OpenAPI/Swagger spec and use
- *      fast, schema-aware serialization.
- *   2. In non-production environments they additionally *validate* the outgoing
- *      payload (see `installResponseValidation`), so an accidental change to a
- *      response shape fails loudly in tests instead of shipping silently.
- *
- * NOTE: response validation has no runtime impact in production — it is only
- * installed when NODE_ENV !== 'production'. In production Fastify falls back to
- * its default (fast) serializer for these same schemas.

-   * When the publisher writes to the SEP-40 feed.

-   * that charges for gas publishes on CHANGE. These are the three knobs that
-   * make that true, and the ceiling that keeps a bad change off chain:
-   *
-   * - `deviationPct`     — publish when the aggregate has moved at least this
-   *                        much from the value already on chain.
-   * - `maxIntervalMs`    — and publish even without movement once this long has
-   *                        passed, so a quiet market does not leave consumers
-   *                        reading a feed with no recent timestamp.
-   * - `minWriteIntervalMs` — the floor between two writes for the same asset,
-   *                        whatever triggered them. This is the rate limit:
-   *                        it bounds the transaction count during a fast market
-   *                        to one per floor, not one per sample.
-   * - `maxAgeSeconds`    — the aggregate itself must be younger than this.
-   *                        Stricter than the API's own stale flag on purpose:
-   *                        the HTTP price can afford to be "as good as we have
-   *                        it", a price a contract settles against cannot.

+   * that charges for gas publishes on CHANGE. These are the three knobs that
+   * make that true, and the ceiling that keeps a bad change off chain:
+   *
+   * - `deviationPct`     — publish when the aggregate has moved at least this
+   *                        much from the value already on chain.
+   * - `maxIntervalMs`    — and publish even without movement once this long has
+   *                        passed, so a quiet market does not leave consumers
+   *                        reading a feed with no recent timestamp.
+   * - `minWriteIntervalMs` — the floor between two writes for the same asset,
+   *                        whatever triggered them. This is the rate limit:
+   *                        it bounds the transaction count during a fast market
+   *                        to one per floor, not one per sample.
+   * - `maxAgeSeconds`    — the aggregate itself must be younger than this.
+   *                        Stricter than the API's own stale flag on purpose:
+   *                        the HTTP price can afford to be "as good as we have
+   *                        it", a price a contract settles against cannot.

-/**
- * Coinbase Exchange CEX Adapter
- *
- * The first concrete CexAdapter, shipped as the pattern every other
- * centralized-exchange adapter (Binance, Kraken, …) should follow. It wraps
- * Coinbase Exchange's public market-data REST endpoints — no API key required.
- *
- * Design contract (issue #215):
- * - fetchTicker / fetchOrderBook normalise the Lens canonical pair ("XLM/USD")
- *   into the exchange's own identifier ("XLM-USD") and back, because the
- *   exchange literally names the pair differently — a slash-form request 404s.
- * - Requests are throttled to Coinbase's published public limit (10 req/s per
- *   IP, bursts up to 15) with a token bucket, and a 429 backs off using the
- *   Retry-After header when present, otherwise exponentially.
- * - Any failure — outage, timeout, non-2xx, malformed body — degrades to a null
- *   return. The adapter never throws, so a dead exchange cannot take down the
- *   process; callers simply get no CEX price for that pair.
- * - Prices carry a distinct `source` ('coinbase_cex') so a CEX number is never
- *   mistaken for, or blended with, an on-chain one.
- *
- * No contract IDs or issuer addresses are involved: this is a pure HTTP market
- * data adapter, so nothing here needs a pasted-on-chain identifier.

+/**
+ * Coinbase Exchange CEX Adapter
+ *
+ * The first concrete CexAdapter, shipped as the pattern every other
+ * centralized-exchange adapter (Binance, Kraken, …) should follow. It wraps
+ * Coinbase Exchange's public market-data REST endpoints — no API key required.
+ *
+ * Design contract (issue #215):
+ * - fetchTicker / fetchOrderBook normalise the Lens canonical pair ("XLM/USD")
+ *   into the exchange's own identifier ("XLM-USD") and back, because the
+ *   exchange literally names the pair differently — a slash-form request 404s.
+ * - Requests are throttled to Coinbase's published public limit (10 req/s per
+ *   IP, bursts up to 15) with a token bucket, and a 429 backs off using the
+ *   Retry-After header when present, otherwise exponentially.
+ * - Any failure — outage, timeout, non-2xx, malformed body — degrades to a null
+ *   return. The adapter never throws, so a dead exchange cannot take down the
+ *   process; callers simply get no CEX price for that pair.
+ * - Prices carry a distinct `source` ('coinbase_cex') so a CEX number is never
+ *   mistaken for, or blended with, an on-chain one.
+ *
+ * No contract IDs or issuer addresses are involved: this is a pure HTTP market
+ * data adapter, so nothing here needs a pasted-on-chain identifier.

-/**
- * DeFindex Vault Venue Adapter
- *
- * DeFindex vaults (Stellar Soroban) pool underlying assets across strategies
- * and issue a share token. A vault share is an asset people actually hold, but
- * its value is never quoted on an order book — it is implied by the vault's own
- * on-chain accounting. This adapter reads that accounting and derives the share
- * price, storing it in price_points with source = 'defindex_vault'.
- *
- * The share price is DERIVED, never TRADED, and never taken from a published
- * figure that could be stale. It comes straight from on-chain state on every
- * read, using the same integer ratio the vault itself uses when redeeming
- * shares:
- *
- *   sharePrice = totalManagedAssets / totalShareSupply        (1 share, in underlying units)
- *
- * A vault with zero shares has no meaningful share price, so the derivation
- * returns 0 and the point is skipped rather than dividing by zero.
- *
- * Every DeFindex contract id used here is copied whole from the protocol's own
- * published deployments (https://github.com/defindex-io/stellar-contracts,
- * public/{mainnet,testnet}.contracts.json) and flows in via config; nothing is
- * elided or invented.
- *
- * Issue: #214

+ * DeFindex vaults (Stellar Soroban) pool underlying assets across strategies
+ * and issue a share token. A vault share is an asset people actually hold, but
+ * its value is never quoted on an order book — it is implied by the vault's own
+ * on-chain accounting. This adapter reads that accounting and derives the share
+ * price, storing it in price_points with source = 'defindex_vault'.
+ *
+ * The share price is DERIVED, never TRADED, and never taken from a published
+ * figure that could be stale. It comes straight from on-chain state on every
+ * read, using the same integer ratio the vault itself uses when redeeming
+ * shares:
+ *
+ *   sharePrice = totalManagedAssets / totalShareSupply        (1 share, in underlying units)
+ *
+ * A vault with zero shares has no meaningful share price, so the derivation
+ * returns 0 and the point is skipped rather than dividing by zero.
+ *
+ * Every DeFindex contract id used here is copied whole from the protocol's own
+ * published deployments (https://github.com/defindex-io/stellar-contracts,
+ * public/{mainnet,testnet}.contracts.json) and flows in via config; nothing is

- * revenue leak. When x402 is not configured, `public` is safe and used.

-/**
- * Server-Side Request Forgery (SSRF) guard for outbound fetches whose target is
- * supplied by an untrusted caller (e.g. an agent driving the Bazaar MCP server).
- *
- * The threat: the server runs wherever the operator runs it — often a machine
- * with network reach the caller does *not* have — and will happily fetch a cloud
- * instance metadata endpoint (`169.254.169.254`) or a service on a private
- * address, then hand the response body straight back to the caller. The
- * mitigation is to refuse any target that is not a public http/https host, and
- * to decide that *after* resolving the hostname, because a public-looking name
- * can resolve to a private address — the classic way this check is bypassed.
- *
- * What is and is not guaranteed:
- *   - Guaranteed: Hostnames and IP literals are validated against private,
- *     loopback, link-local, and cloud metadata IP ranges.
- *   - Guaranteed: DNS rebinding defense — connect-time resolution is pinned to
- *     an address that was explicitly validated during the pre-flight check,
- *     preventing short-TTL DNS records from redirecting the socket to a private
- *     address at connect time.
- *   - Guaranteed: TLS certificate and SNI verification are performed against the
- *     original hostname, preserving TLS security and host verification.
- *   - Guaranteed: Redirects are followed manually (`redirect: 'manual'`) and
- *     every redirect hop is re-validated and re-pinned.
- *   - Not guaranteed: Host-level application vulnerabilities or semantic contents
- *     served by a legitimately public host.
- *
- * Design notes:
- *   - Private/loopback/link-local/metadata addresses are always refused. The
- *     optional `allowedHosts` list only *narrows* what is reachable; it can never
- *     re-open a blocked address. There is no config that turns the block off.
- *   - Redirects are followed manually (`redirect: 'manual'`) and every hop is put
- *     through the same checks. A permitted host that 302s to a metadata endpoint
- *     is refused exactly as if the caller had named it directly.
- *   - `lookup` and `fetchImpl` are injectable so the resolution behaviour can be
- *     tested without real DNS or sockets.

+/**
+ * Server-Side Request Forgery (SSRF) guard for outbound fetches whose target is
+ * supplied by an untrusted caller (e.g. an agent driving the Bazaar MCP server).
+ *
+ * The threat: the server runs wherever the operator runs it — often a machine
+ * with network reach the caller does *not* have — and will happily fetch a cloud
+ * instance metadata endpoint (`169.254.169.254`) or a service on a private
+ * address, then hand the response body straight back to the caller. The
+ * mitigation is to refuse any target that is not a public http/https host, and
+ * to decide that *after* resolving the hostname, because a public-looking name
+ * can resolve to a private address — the classic way this check is bypassed.
+ *
+ * What is and is not guaranteed:
+ *   - Guaranteed: Hostnames and IP literals are validated against private,
+ *     loopback, link-local, and cloud metadata IP ranges.
+ *   - Guaranteed: DNS rebinding defense — connect-time resolution is pinned to
+ *     an address that was explicitly validated during the pre-flight check,
+ *     preventing short-TTL DNS records from redirecting the socket to a private
+ *     address at connect time.
+ *   - Guaranteed: TLS certificate and SNI verification are performed against the
+ *     original hostname, preserving TLS security and host verification.
+ *   - Guaranteed: Redirects are followed manually (`redirect: 'manual'`) and
+ *     every redirect hop is re-validated and re-pinned.
+ *   - Not guaranteed: Host-level application vulnerabilities or semantic contents
+ *     served by a legitimately public host.
+ *
+ * Design notes:
+ *   - Private/loopback/link-local/metadata addresses are always refused. The
+ *     optional `allowedHosts` list only *narrows* what is reachable; it can never
+ *     re-open a blocked address. There is no config that turns the block off.
+ *   - Redirects are followed manually (`redirect: 'manual'`) and every hop is put
+ *     through the same checks. A permitted host that 302s to a metadata endpoint
+ *     is refused exactly as if the caller had named it directly.
+ *   - `lookup` and `fetchImpl` are injectable so the resolution behaviour can be
+ *     tested without real DNS or sockets.

-/**
- * The SEP-40 publisher loop (#222).
- *
- * This is the piece that turns Lens from an oracle consumer into an oracle
- * publisher: read our own aggregate, compare it with what the feed already
- * holds, and — only when `trigger.ts` says the move justifies a transaction —
- * write it. It runs once per enabled network, exactly like the ingest loops it
- * sits next to, and it is the only code in Lens that signs a transaction.
- *
- * Three structural choices worth stating, because they are the ones a reviewer
- * should push on:
- *
- * **Everything the loop depends on is injected.** `runPublicationCycle` takes a
- * `PublicationDeps` — the feed, the aggregate source, the venue source, the
- * audit sink — so the whole policy is exercised in tests against recording
- * fakes, including "the chain was never touched". Production wires the real
- * ones; there is no separate mock mode.
- *
- * **The feed's own parameters decide the math.** `base`, `decimals` and
- * `resolution` are read from the deployed contract, never from an env var, so a
- * mis-declared scale cannot produce a price off by four orders of magnitude. If
- * those reads fail, the cycle aborts before any pair is attempted.
- *
- * **Which leg is published is derived, not configured.** SEP-40 quotes every
- * asset against ONE base, while Lens stores a pair as `price = assetB per
- * assetA`. The base tells us which leg of the pair is quoted and whether the
- * number has to be inverted; a pair whose legs are neither of them is skipped
- * with a reason, because publishing it would put a ratio under the wrong
- * label.

+/**
+ * The SEP-40 publisher loop (#222).
+ *
+ * This is the piece that turns Lens from an oracle consumer into an oracle
+ * publisher: read our own aggregate, compare it with what the feed already
+ * holds, and — only when `trigger.ts` says the move justifies a transaction —
+ * write it. It runs once per enabled network, exactly like the ingest loops it
+ * sits next to, and it is the only code in Lens that signs a transaction.
+ *
+ * Three structural choices worth stating, because they are the ones a reviewer
+ * should push on:
+ *
+ * **Everything the loop depends on is injected.** `runPublicationCycle` takes a
+ * `PublicationDeps` — the feed, the aggregate source, the venue source, the
+ * audit sink — so the whole policy is exercised in tests against recording
+ * fakes, including "the chain was never touched". Production wires the real
+ * ones; there is no separate mock mode.
+ *
+ * **The feed's own parameters decide the math.** `base`, `decimals` and
+ * `resolution` are read from the deployed contract, never from an env var, so a
+ * mis-declared scale cannot produce a price off by four orders of magnitude. If
+ * those reads fail, the cycle aborts before any pair is attempted.
+ *
+ * **Which leg is published is derived, not configured.** SEP-40 quotes every
+ * asset against ONE base, while Lens stores a pair as `price = assetB per
+ * assetA`. The base tells us which leg of the pair is quoted and whether the
+ * number has to be inverted; a pair whose legs are neither of them is skipped
+ * with a reason, because publishing it would put a ratio under the wrong
+ * label.

-/**
- * Register the whole-network snapshot endpoint.
- *
- * GET /snapshot?network=testnet|mainnet
- *
- * One call that answers "what does this network look like right now": every
- * venue's liveness, AMM liquidity (TVL), 24h volume, the busiest pairs, the
- * stablecoin peg readings and how fresh the underlying data is — as a single
- * timestamped object rather than four or five round-trips.
- *
- * Design rules, all in service of not lying:
- *
- *   - Everything is read in ONE SQL statement with a single `as_of` timestamp
- *     taken from the database. Four separate queries could land on four
- *     different clocks, and then the response would describe an instant that
- *     never existed. Every 24h cutoff and every `ageSeconds` is measured from
- *     that same `as_of`.
- *   - Scoped to exactly one network. Testnet and mainnet rows pooled together
- *     are not a market; `network` defaults to this process's own network and
- *     the resolved value is echoed back.
- *   - Absent data is reported, never invented. A venue with no rows is listed
- *     as silent, a pair with no trades in the window gets no volume figure,
- *     the peg check says `no_reference` when it has nothing to compare against,
- *     and a cross-pair volume total is null — with a reason — when the pairs do
- *     not share a unit. The `provenance`/`note` fields carry the same honesty.
- *   - Asset identity is never elided. Where full ids are known (they are, from
- *     the pair_config's watched pairs / the price-point pair key) the issuer is
- *     included, because a coin called "USDC" is a different asset per issuer.
- *   - Always 200. This endpoint summarises state; "no data yet" is state, not a
- *     client error, and a summary that 404s is useless to a dashboard.
- *
- * Cached per network for a few seconds so a dashboard polling it cannot turn
- * into a full table scan per request. The cached whole response carries its own
- * `cache.ageSeconds`, so a hit never pretends to be fresher than it is.

+/**
+ * Register the whole-network snapshot endpoint.
+ *
+ * GET /snapshot?network=testnet|mainnet
+ *
+ * One call that answers "what does this network look like right now": every
+ * venue's liveness, AMM liquidity (TVL), 24h volume, the busiest pairs, the
+ * stablecoin peg readings and how fresh the underlying data is — as a single
+ * timestamped object rather than four or five round-trips.
+ *
+ * Design rules, all in service of not lying:
+ *
+ *   - Everything is read in ONE SQL statement with a single `as_of` timestamp
+ *     taken from the database. Four separate queries could land on four
+ *     different clocks, and then the response would describe an instant that
+ *     never existed. Every 24h cutoff and every `ageSeconds` is measured from
+ *     that same `as_of`.
+ *   - Scoped to exactly one network. Testnet and mainnet rows pooled together
+ *     are not a market; `network` defaults to this process's own network and
+ *     the resolved value is echoed back.
+ *   - Absent data is reported, never invented. A venue with no rows is listed
+ *     as silent, a pair with no trades in the window gets no volume figure,
+ *     the peg check says `no_reference` when it has nothing to compare against,
+ *     and a cross-pair volume total is null — with a reason — when the pairs do
+ *     not share a unit. The `provenance`/`note` fields carry the same honesty.
+ *   - Asset identity is never elided. Where full ids are known (they are, from
+ *     the pair_config's watched pairs / the price-point pair key) the issuer is

-/**
- * Websocket backpressure policy.
- *
- * `WebSocket#send()` neither blocks nor throws when the peer is merely slow —
- * it queues. A client on a bad mobile connection, or one whose process has been
- * suspended, accumulates price updates in its socket's internal buffer, and
- * nothing inspects `bufferedAmount`, so that buffer has no upper bound. With a
- * price feed running continuously, one stuck subscriber is enough to grow the
- * process until it is OOM-killed, taking every other subscriber with it.
- *
- * The policy, in three tiers, is implemented in `FanOutManager.deliver`:
- *
- *  1. **Coalesce** — past {@link BackpressureLimits.slowClientBufferBytes}, or
- *     inside the coalescing window, keep only the newest update and drop the
- *     ones it supersedes. For a price feed an intermediate tick that arrives
- *     late is worthless: the newest tick has already superseded it, so the
- *     backlog is truncated rather than drained. This is the tier that actually
- *     saves a healthy-but-slow client, and the one most clients hit.
- *  2. **Disconnect** — past {@link BackpressureLimits.maxBufferedBytes}, close
- *     the socket with {@link CLOSE_CODE_SLOW_CONSUMER}. No amount of coalescing
- *     fixes a peer that has stopped reading entirely; what bounds it is not
- *     letting its buffer grow.
- *  3. **Evict** — congested for longer than
- *     {@link BackpressureLimits.maxCongestedMs}, close it too. Tier 1 bounds the
- *     memory such a client costs; this bounds the time. Without it a client that
- *     stopped reading holds its slot, its buffered bytes and a
- *     `ws_clients_total` series forever, and nothing would say why.
- *
- * A stalled client can never affect another one: the thresholds are read per
- * client, dropping one only touches that client's own socket, and every send is
- * individually guarded.
- *
- * Resolved once at import (see `FanOutManager`), because this is read on the
- * price-update path.

+/**
+ * Websocket backpressure policy.
+ *
+ * `WebSocket#send()` neither blocks nor throws when the peer is merely slow —
+ * it queues. A client on a bad mobile connection, or one whose process has been
+ * suspended, accumulates price updates in its socket's internal buffer, and
+ * nothing inspects `bufferedAmount`, so that buffer has no upper bound. With a
+ * price feed running continuously, one stuck subscriber is enough to grow the
+ * process until it is OOM-killed, taking every other subscriber with it.
+ *
+ * The policy, in three tiers, is implemented in `FanOutManager.deliver`:
+ *
+ *  1. **Coalesce** — past {@link BackpressureLimits.slowClientBufferBytes}, or
+ *     inside the coalescing window, keep only the newest update and drop the
+ *     ones it supersedes. For a price feed an intermediate tick that arrives
+ *     late is worthless: the newest tick has already superseded it, so the
+ *     backlog is truncated rather than drained. This is the tier that actually
+ *     saves a healthy-but-slow client, and the one most clients hit.
+ *  2. **Disconnect** — past {@link BackpressureLimits.maxBufferedBytes}, close
+ *     the socket with {@link CLOSE_CODE_SLOW_CONSUMER}. No amount of coalescing
+ *     fixes a peer that has stopped reading entirely; what bounds it is not
+ *     letting its buffer grow.
+ *  3. **Evict** — congested for longer than
+ *     {@link BackpressureLimits.maxCongestedMs}, close it too. Tier 1 bounds the
+ *     memory such a client costs; this bounds the time. Without it a client that
+ *     stopped reading holds its slot, its buffered bytes and a
+ *     `ws_clients_total` series forever, and nothing would say why.
+ *
+ * A stalled client can never affect another one: the thresholds are read per
+ * client, dropping one only touches that client's own socket, and every send is
+ * individually guarded.
+ *
+ * Resolved once at import (see `FanOutManager`), because this is read on the
+ * price-update path.

- *
- * The baseline test (tests/prisma-migrations.test.ts) proves the committed SQL
- * reproduces schema.prisma, and the CI `db-migrations` job proves the
- * migrations apply to an empty Postgres. Neither covers the state production is
- * actually in: full schema, no `_prisma_migrations` table. There,
- * `migrate deploy` runs the baseline's CREATE TABLEs against tables that exist
- * and errors — and because src/index.ts ends in `process.exit(1)`, that is a
- * crash loop rather than a failed migration.
- *
- * So these tests pin the command sequence for each of the three states a
- * database can be in. They are DB-free: the queryable and the command runner
- * are both injected, so what is under test is the decision, not Postgres.

- * (so a database blip never makes the orchestrator kill healthy processes), and
- * `/ready` must actually reflect them (so a process that cannot serve is not
- * sent traffic).
- *
- * Boot state matters as much as the dependency checks. `app.listen()` runs part-
- * way through `main()`, before the ingesters exist, so a process that is
- * listening is not yet able to serve — hence `/ready` being unhealthy until

-// Regression tests for network-scoped ingest metrics.
-//
-// Every ingester runs once per ENABLED network against one shared prom-client
-// Registry (see src/metrics.ts). Before `network` was a label on the ingest
-// metrics, both loops wrote to the same series for the same pair. For the
-// counters that meant a silent merge; for `last_trade_timestamp` — a
-// `Gauge.set()`, i.e. last-writer-wins — the testnet loop could overwrite the
-// mainnet value outright, which made the only staleness signal Lens exports
-// unusable on a dual-network deployment.
-//
-// These tests drive the real ingesters rather than poking the registry, so a
-// call site that forgets the label fails here too.

-/**
- * Load test for the price endpoints fronted by trading bots.
- *
- * Acceptance criteria: p95 < 80ms at 5k RPS.
- *
- * The test drives `GET /price/:assetA/:assetB` — the hot path bots poll. It uses
- * a constant-arrival-rate executor so the load is expressed in requests/second
- * (open model), independent of how fast the server responds. k6 scales the VU
- * pool to sustain the target rate.
- *
- * Also tests WebSocket fan-out with backpressure by simulating slow consumers.
- *
- * Configuration (all via environment variables):
- *   BASE_URL   Target host.            Default: http://localhost:3002
- *   RATE       Target requests/sec.    Default: 5000
- *   DURATION   Steady-state duration.  Default: 1m
- *   API_KEY    Bearer token to send.   Default: none
- *   PAIRS      Comma-separated list of assetA/assetB pairs.
- *              Default: XLM/USDC
- *   WS_CLIENTS Number of simulated WebSocket clients. Default: 100

+ * Load test for the price endpoints fronted by trading bots.
+ *
+ * Acceptance criteria: p95 < 80ms at 5k RPS.
+ *
+ * The test drives `GET /price/:assetA/:assetB` — the hot path bots poll. It uses
+ * a constant-arrival-rate executor so the load is expressed in requests/second
+ * (open model), independent of how fast the server responds. k6 scales the VU
+ * pool to sustain the target rate.
+ *
+ * Also tests WebSocket fan-out with backpressure by simulating slow consumers.
+ *
+ * Configuration (all via environment variables):
+ *   BASE_URL   Target host.            Default: http://localhost:3002
+ *   RATE       Target requests/sec.    Default: 5000
+ *   DURATION   Steady-state duration.  Default: 1m
+ *   API_KEY    Bearer token to send.   Default: none
+ *   PAIRS      Comma-separated list of assetA/assetB pairs.
+ *              Default: XLM/USDC
+ *   WS_CLIENTS Number of simulated WebSocket clients. Default: 100

- * #416 — a tool result is written straight into an agent's context window, so an
- * unbounded one is self-inflicted denial of service whose failure gets blamed on
- * the model. These tests pin the four things that make a result safe to hand
- * back: a byte ceiling, an explicit truncation label, no pretty-printing, and a
- * bounded page plus a count wherever paging is something the agent can ask for.
- *
- * They also pin the second half of the fix, which is the part that cannot be
- * undone by a client: the body read from upstream is capped while streaming, so
- * an oversized response is never buffered in full here.

- * #233 — There is no migration history, only `db push`.
- *
- * The defect this guards against is invisible to every other test in the repo:
- * `prisma/` shipped only `schema.prisma`, and every schema change was applied
- * with `prisma db push`, which diffs the live DB against the schema and applies
- * whatever it decides. Nothing in the codebase could detect a schema that had
- * drifted away from any committed, reviewable migration.
- *
- * These tests are the "fails first" proof. Before adoption `prisma/migrations`
- * does not exist, so `has a committed migration history` fails; the moment the
- * baseline lands it passes. The drift test then locks `schema.prisma` and the
- * baseline together: edit the schema without regenerating a migration and the
- * two diverge, exactly the failure mode #233 exists to prevent.
- *
- * They are deliberately DB-free: they only run
- * `prisma migrate diff --from-empty --to-schema-datamodel`, which reads the
- * schema file and never opens a connection, so they run inside plain `npm test`
- * and the CI build job with no Postgres present. The general, multi-migration
- * drift guard (replaying every migration against a real database) lives in the
- * `db-migrations` CI job and scripts/db-drift-check.sh, both of which need a
- * live database. Adopting the baseline on a database that predates the history
- * is a third, separate concern: tests/db-migrate-baseline.test.ts.

-/**
- * End-to-end coverage for the *successful* x402 payment loop (#423).
- *
- * The pre-existing 402 tests in tests/mcp.test.ts mock `fetchWithPayment`, so
- * they only ever exercise a rejected payment mapping to ERR_PAYMENT_REJECTED.
- * Nothing drove the branch that actually moves money: 402 -> construct a
- * payment -> sign it -> submit it -> resource returned. That branch is the one
- * that would break silently on an x402 or Stellar SDK upgrade.
- *
- * Here the whole loop runs for real:
- *   - the x402 client + transport (`wrapFetchWithPaymentFromConfig`) is the
- *     production one, so header encoding / requirement parsing / payment
- *     selection / spend-control enforcement are all exercised.
- *   - the payment is signed with the real `@stellar/stellar-sdk` primitives
- *     (`authorizeInvocation`, Soroban `transfer` invocation, network
- *     passphrase), so an SDK change to any of those surfaces fails the test.
- *
- * Only two things are stubbed, and both are stubs on purpose:
- *   - the *resource + facilitator*, replaced by an in-process fake that demands
- *     payment, decodes the submitted `PAYMENT-SIGNATURE`, verifies it against
- *     the Stellar testnet network passphrase, and only then releases the
- *     resource; and
- *   - the Soroban RPC / Horizon that `ExactStellarScheme.createPaymentPayload`
- *     would otherwise call for `getLatestLedger` + `simulateTransaction`.
- *     Driving the real scheme needs those network round-trips, which would
- *     break "deterministic and needs no network access", so the scheme client
- *     builds the transfer invocation directly. The cryptography it runs is the
- *     SDK's own, which is exactly what the upgrade risk is about.
- *
- * All keys are generated per-test and are throwaway testnet accounts: never a
- * real secret, never a mainnet account, never committed.

+ * End-to-end coverage for the *successful* x402 payment loop (#423).
+ *
+ * The pre-existing 402 tests in tests/mcp.test.ts mock `fetchWithPayment`, so
+ * they only ever exercise a rejected payment mapping to ERR_PAYMENT_REJECTED.
+ * Nothing drove the branch that actually moves money: 402 -> construct a
+ * payment -> sign it -> submit it -> resource returned. That branch is the one
+ * that would break silently on an x402 or Stellar SDK upgrade.
+ *
+ * Here the whole loop runs for real:
+ *   - the x402 client + transport (`wrapFetchWithPaymentFromConfig`) is the
+ *     production one, so header encoding / requirement parsing / payment
+ *     selection / spend-control enforcement are all exercised.
+ *   - the payment is signed with the real `@stellar/stellar-sdk` primitives
+ *     (`authorizeInvocation`, Soroban `transfer` invocation, network
+ *     passphrase), so an SDK change to any of those surfaces fails the test.
+ *
+ * Only two things are stubbed, and both are stubs on purpose:
+ *   - the *resource + facilitator*, replaced by an in-process fake that demands
+ *     payment, decodes the submitted `PAYMENT-SIGNATURE`, verifies it against
+ *     the Stellar testnet network passphrase, and only then releases the
+ *     resource; and
+ *   - the Soroban RPC / Horizon that `ExactStellarScheme.createPaymentPayload`
+ *     would otherwise call for `getLatestLedger` + `simulateTransaction`.
+ *     Driving the real scheme needs those network round-trips, which would
+ *     break "deterministic and needs no network access", so the scheme client
+ *     builds the transfer invocation directly. The cryptography it runs is the
+ *     SDK's own, which is exactly what the upgrade risk is about.
+ *
+ * All keys are generated per-test and are throwaway testnet accounts: never a
+ * real secret, never a mainnet account, never committed.
