It times the job via WorkerMetricsService when available, logs a structured completion record, and classifies failures before rethrowing: transient failures log a job.retrying warning, while a failure on the final attempt or an UnrecoverableError logs a job.dead-lettered error with the scrubbed payload and stack. The original error is always rethrown untouched so BullMQ retry semantics are preserved, and logging can never mask it. Add scrubForLog/scrubString, which redact sensitive keys (sharing the audit sanitizer's key list) and secret-shaped substrings such as Stellar seeds, bearer tokens and URL credentials, and coerce cycles, bigints and errors into JSON-safe values. QueueFailureListener now scrubs its log line as well; previously the raw webhook payload, including its signing secret, was written to the error log. The dead-letter copy keeps the raw payload so re-drive still works. --- src/common/helpers/audit-sanitizer.ts | 7 +- src/queues/queue-failure-listener.spec.ts | 26 ++ src/queues/queue-failure-listener.ts | 10 +- src/utils/log-scrubber.util.spec.ts | 95 +++++++ src/utils/log-scrubber.util.ts | 85 +++++++ src/workers/analytics-aggregation.worker.ts | 18 +- src/workers/balance.worker.ts | 17 +- src/workers/job-worker.spec.ts | 265 ++++++++++++++++++++ src/workers/job-worker.ts | 175 +++++++++++++ src/workers/notification-delivery.worker.ts | 18 +- src/workers/webhook-delivery.worker.ts | 18 +- 11 files changed, 702 insertions(+), 32 deletions(-) create mode 100644 src/utils/log-scrubber.util.spec.ts create mode 100644 src/utils/log-scrubber.util.ts create mode 100644 src/workers/job-worker.spec.ts create mode 100644 src/workers/job-worker.ts diff --git a/src/common/helpers/audit-sanitizer.ts b/src/common/helpers/audit-sanitizer.ts index 737cc298..5e2e28d5 100644 --- a/src/common/helpers/audit-sanitizer.ts +++ b/src/common/helpers/audit-sanitizer.ts @@ -33,6 +33,11 @@ const SENSITIVE_FIELDS = new Set([ /** Sentinel value used to replace scrubbed secrets while preserving structure. */ export const REDACTED = '[REDACTED]';

Batches the 3 counts and 2 aggregates into a single $transaction([...]) call; the 2 groupBy calls stay outside the batch since Prisma's groupBy return type doesn't infer correctly inside a $transaction array. Response shape is unchanged. Existing indexes on organizationId/status/createdAt already cover these queries. * test(audit): cover pagination and sorting edge cases for activity log Closes #339 The audit log (this repo's activity log) already supported page/limit/sort/order/filter query params and returned pagination metadata (total, totalPages, hasNext, hasPrev), with limit capped at 100. Adds unit test coverage for the previously-untested list() method: normal pagination, empty results, out-of-bounds pages, invalid sort field fallback, ascending order, and entity filtering. * fix(migrations): resolve colliding timestamp between two merged migrations Migrations 20260928120000_add_agent_contribution_stats_index and 20260928120000_add_notifications_user_created_at_index landed with the same 14-digit timestamp prefix from two separately merged PRs (#374, #357), which scripts/verify-migrations.sh rejects as a conflict. Bumps the notifications index migration to 20260928120001; both migrations are independent, additive CREATE INDEX statements with no ordering dependency between them, so the rename is safe. * fix(ci): document missing env vars and fix flaky retry.util test Two pre-existing, unrelated-to-this-PR CI failures fixed while unblocking this branch: - docs/configuration.md was missing 7 env vars added by recent merges (DATABASE_SLOW_QUERY_THRESHOLD_MS, DATABASE_CONNECT_RETRY_ATTEMPTS, DATABASE_CONNECT_RETRY_DELAY_MS, PUBLIC_RATE_LIMIT_*), which env.validation.spec.ts asserts against. Documented all 7. - retry.util.spec.ts had 3 tests that create a rejecting promise, advance fake timers with vi.runAllTimersAsync(), then attach the rejection assertion afterward — a race that surfaces as an unhandled rejection under full-suite load (deterministic once >100 files run together). Attaching a no-op .catch() immediately after creating the promise prevents the unhandled state without changing what each test asserts. --- docs/configuration.md | 7 ++ .../migration.sql | 0 src/modules/analytics/analytics.repository.ts | 79 ++++++++-------- .../analytics/analytics.service.spec.ts | 80 ++++++++++++++++ src/modules/analytics/analytics.service.ts | 12 +-- src/modules/audit/audit.service.spec.ts | 91 +++++++++++++++++-- src/utils/retry.util.spec.ts | 3 + 7 files changed, 219 insertions(+), 53 deletions(-) rename prisma/migrations/{20260928120000_add_notifications_user_created_at_index => 20260928120001_add_notifications_user_created_at_index}/migration.sql (100%) create mode 100644 src/modules/analytics/analytics.service.spec.ts diff --git a/docs/configuration.md b/docs/configuration.md index b1c2243a..7501d188 100644 --- a/docs/configuration.md +++ b/docs/configuration.md @@ -84,6 +84,9 @@ are rejected: | `DATABASE_QUERY_TIMEOUT_MS` | `5000` | Client-side query timeout for the API pool. `0` disables it. | | `DATABASE_STATEMENT_TIMEOUT_MS` | `10000` | Server-side `statement_timeout`. `0` disables it. | | `DATABASE_WORKER_QUERY_TIMEOUT_MS` | `60000` | Client-side query timeout for the worker pool. `0` disables it. | +| `DATABASE_SLOW_QUERY_THRESHOLD_MS` | `1000` | Queries slower than this are logged as slow queries. | +| `DATABASE_CONNECT_RETRY_ATTEMPTS` | `5` | Connection attempts before giving up on startup. | +| `DATABASE_CONNECT_RETRY_DELAY_MS` | `1000` | Delay between connection retry attempts. | ### Redis @@ -140,6 +143,10 @@ are rejected: | `THROTTLE_TTL` | `60` | Throttler window in seconds. | | `RATE_LIMIT_WINDOW_SECONDS` | `60` | Sliding-window size for the Redis rate-limiter guard. | | `RATE_LIMIT_MAX_REQUESTS` | `120` | Requests allowed per client per sliding window. | +| `PUBLIC_RATE_LIMIT_ENABLED` | `true` | Enables the IP-based limiter for unauthenticated (`@Public()`) routes. | +| `PUBLIC_RATE_LIMIT_MAX_REQUESTS` | `60` | Requests allowed per client IP per sliding window on public routes. | +| `PUBLIC_RATE_LIMIT_WINDOW_SECONDS` | `60` | Sliding-window size for the public-route rate limiter. | +| `PUBLIC_RATE_LIMIT_TRUST_PROXY` | `false` | Reads client IP from `X-Forwarded-For`.

Removed its now-orphaned tests too. - agent.controller.ts: AstroidThrottlerGuard used but never imported; dropped an unused SlidingWindowThrottlerGuard import block - risk.service.ts: event-driven risk scoring built a RiskFactorsInput with fields (destination/velocityCount/isNewRecipient) that don't exist on the current type;

charset=UTF-8 Content-Transfer-Encoding: 8bit Every authenticated request performed a Redis round trip against the token blacklist to answer "is this session still revoked?". This adds a short-TTL caching layer in front of the blacklist so repeated verifications within one window skip the Redis query entirely. - Add CacheService: a small get/set/delete cache over the shared REDIS_CLIENT with TTL-bounded entries, JSON payloads, and SCAN-based prefix invalidation. Every operation degrades to a no-op/miss on Redis failure so caching can never break the request path. - Add TokenVerificationCacheService: caches per-session revocation answers for TOKEN_CACHE_TTL seconds (default 30, well below the 15-minute access-token lifetime) and exposes invalidation hooks. - Wire the cache into JwtStrategy.validate (cache-first, source of truth on miss, fail-open unchanged on Redis outages). - Hook invalidation into every revocation path: TokenBlacklistService drops the cached answer after each blacklist write (including on Redis-outage fallback), AuthService invalidates on logout and on refresh rotation, so revocations are observed immediately instead of after the TTL window. Revocation reliability is preserved because no cached answer outlives its TTL, and explicit logout/rotation clears the entry at once. Tests: unit suites for CacheService and TokenVerificationCacheService (hits, misses, resolver fallback, invalidation hooks), an integration suite proving repeated authentications trigger a single blacklist lookup and that logout flips a cached-valid session to 401 immediately, plus updated JwtStrategy/TokenBlacklistService/api-key integration suites for the new wiring.

This makes the public rate limiter configurable per route and per client identifier, on the existing Redis sliding-window counter. - Add @PublicRateLimit(max, windowSeconds) decorator: per-route (or per-controller) budget overrides resolved by the guard through Reflector; the global PUBLIC_RATE_LIMIT_* settings remain the default. - Add PUBLIC_RATE_LIMIT_CLIENT_IDENTIFIERS (optional, comma-separated, currently 'apiKey'): when enabled, a presented x-api-key or ApiKey/Bearer ak_... Authorization header is folded into the bucket key so distinct key-holding clients behind one IP get their own budgets. The IP always participates; keyless callers share the plain-IP bucket as before. - Extract a testable PublicRateLimitGuard.check() returning the full decision (allowed, limit, windowSeconds, count, resetAt); canActivate keeps its existing 429 + X-RateLimit-Limit/Remaining/Reset + Retry-After contract and in-memory fallback on Redis outage. Tests: unit suites for per-route rule resolution, identifier bucketing (with/without identifiers configured), header correctness on allowed and limited requests, and @SkipPublicRateLimit() interaction with rules; an HTTP-level integration suite simulating bursts that proves the 429-with-headers behaviour at the global limit, per-route overrides (next to unaffected sibling routes), and per-key budget isolation. Existing public-rate-limit suites pass unchanged (bucket keys keep the ip: prefix, so stored counters stay compatible).

Each record captures the actor (human user id or acting agent), client IP, HTTP method, request path, a SHA-256 fingerprint of the sanitized payload, the sanitized body itself, the final response status and handler duration. Secrets, keys, tokens, signatures and mnemonics are redacted recursively without mutating the original request body, and @SkipAudit() always wins. Applied to the sensitive policy, budget and API-key endpoints; persistence stays fire-and-forget so a failed audit write never breaks the client request. --- src/common/decorators/audit-log.decorator.ts | 42 +++ .../audit-log.interceptor.spec.ts | 321 +++++++++++------- .../interceptors/audit-log.interceptor.ts | 154 ++++++--- src/modules/budgets/budget.controller.ts | 5 + src/modules/developer/api-key.controller.ts | 3 + src/modules/policies/policy.controller.ts | 4 + 6 files changed, 358 insertions(+), 171 deletions(-) create mode 100644 src/common/decorators/audit-log.decorator.ts diff --git a/src/common/decorators/audit-log.decorator.ts b/src/common/decorators/audit-log.decorator.ts new file mode 100644 index 00000000..91f170c1 --- /dev/null +++ b/src/common/decorators/audit-log.decorator.ts @@ -0,0 +1,42 @@ +import { SetMetadata } from '@nestjs/common'; + +/** Metadata key read by `AuditLogInterceptor` through the Nest Reflector. */ +export const AUDIT_LOG_KEY = 'astroid:auditLog'; + +/** + * Per-route audit metadata.

Every method funnels through one error-handling wrapper that logs the operation (plus the Prisma error code) and rethrows the original error, so error handling and transaction safety are uniform across the repository. Adds SpendingPolicyService, which injects the repository and now owns spending-policy validation and enforcement (staleness checks, daily velocity limit, evaluation audit) with no direct Prisma access. PolicyService is reduced to orchestration - domain events plus the pure PolicyEngine - and delegates all persistence to SpendingPolicyService, which removes the direct prisma.transaction/prisma.auditLog calls from the service layer. PolicyRepository is replaced by the new, better-named repository.

Both the queue registration and the enqueue path consume the same constants, so the API and the worker can no longer drift apart. Adds WebhookAuditService, which appends a WEBHOOK_DELIVERY_FAILED record (subscriber, event, attempts, HTTP status, failure reason) to the audit trail for deliveries that will never be retried - either an unrecoverable 4xx or the final attempt after retries are exhausted. Both the webhook processor and the worker call it through a fire-and-forget hook that swallows and logs its own failures, so audit problems can never mask the delivery error, crash the NestJS process or interfere with BullMQ retry/backoff. Tests cover the retry/backoff/DLQ configuration and jitter envelope, the audit service (including persistence failures) and the processor's terminal-failure behaviour - retry without auditing while attempts remain, exactly one audit entry when retries are exhausted or a 4xx is returned, and error preservation when auditing fails. --- .../services/webhook-audit.service.spec.ts | 79 +++++++++++++ .../services/webhook-audit.service.ts | 65 ++++++++++ .../services/webhook-delivery.service.ts | 30 ++--- .../webhooks/webhook-failure-audit.spec.ts | 111 ++++++++++++++++++ src/modules/webhooks/webhook.module.ts | 36 ++---- src/modules/webhooks/webhooks.processor.ts | 38 ++++++ .../webhooks/workers/webhook.worker.ts | 38 ++++++ src/queues/webhook.queue.spec.ts | 56 +++++++++ src/queues/webhook.queue.ts | 54 +++++++++ 9 files changed, 464 insertions(+), 43 deletions(-) create mode 100644 src/modules/webhooks/services/webhook-audit.service.spec.ts create mode 100644 src/modules/webhooks/services/webhook-audit.service.ts create mode 100644 src/modules/webhooks/webhook-failure-audit.spec.ts create mode 100644 src/queues/webhook.queue.spec.ts create mode 100644 src/queues/webhook.queue.ts diff --git a/src/modules/webhooks/services/webhook-audit.service.spec.ts b/src/modules/webhooks/services/webhook-audit.service.spec.ts new file mode 100644 index 00000000..ab85bbb5 --- /dev/null +++ b/src/modules/webhooks/services/webhook-audit.service.spec.ts @@ -0,0 +1,79 @@ +import { beforeEach, describe, expect, it, vi } from 'vitest';

Introduces a third 'agent' tier (THROTTLE_AGENT_LIMIT, default 300/window) alongside api/auth in config/throttler.config.ts and env.validation.ts, and routes each request to exactly one tier - explicit @ThrottleTierDecorator() metadata wins, otherwise agent-identified traffic uses the agent tier and everything else the api tier. Rejections are standard 429s that also carry plain Retry-After, X-RateLimit-Limit and X-RateLimit-Remaining headers, and the tier limit is advertised on allowed responses too. Applied selectively to the agent-facing controllers (agents, transactions, wallets) via @UseGuards so the existing global AstroidThrottlerGuard keeps enforcing api/auth untouched. Vitest coverage asserts tier routing, tracker resolution for agents/orgs/API keys/anonymous callers, header emission and 429 enforcement when a single agent's burst exhausts its budget. --- .env.example | 2 + src/app.module.ts | 10 +- .../decorators/throttle-tier.decorator.ts | 8 +- .../guards/agent-throttler.guard.spec.ts | 225 ++++++++++++++++++ src/common/guards/agent-throttler.guard.ts | 143 +++++++++++ src/common/guards/throttler.guard.spec.ts | 2 +- src/common/index.ts | 3 + src/config/env.validation.ts | 7 + src/config/throttler.config.spec.ts | 17 +- src/config/throttler.config.ts | 11 +- src/modules/agents/agent.controller.ts | 2 + .../transactions/transaction.controller.ts | 2 + src/modules/wallets/wallet.controller.ts | 8 + 13 files changed, 425 insertions(+), 15 deletions(-) create mode 100644 src/common/guards/agent-throttler.guard.spec.ts create mode 100644 src/common/guards/agent-throttler.guard.ts diff --git a/.env.example b/.env.example index 40dc8b43..61539b83 100644 --- a/.env.example +++ b/.env.example @@ -58,6 +58,8 @@ QUEUE_CONCURRENCY=5 # Counters are stored in Redis so every API replica enforces the same budget.

Fixed to get this branch's CI green: - throttler.guard.ts / sliding-window-throttler.guard.ts: AuthenticatedUser has no `sub` or `tier` field; use `.id` and treat `tier` as an optional extension until the type actually carries it. - agent.controller.ts: imported SlidingWindowThrottlerGuard/SlidingWindowLimit (unused) instead of the AstroidThrottlerGuard actually referenced by @UseGuards. - event-names.ts: dropped a duplicate TransactionRiskScoringRequested key. - risk.service.ts: the TransactionCreated handler built a RiskFactorsInput with fields (`destination`, `velocityCount`, `isNewRecipient`) that don't exist on the type; mapped to the real shape instead. Removed dead lowRisk/createEventBus fixtures left over in risk.service.spec.ts. - stellar.service.ts (Soroban variant): fixed getTransactionInfo calling a nonexistent client method (getTransaction), simulateTransaction being called with a bare string instead of {transactionXdr}, and an error message interpolating the whole error object instead of `.message`. Rewrote stellar.service.spec.ts's mocks/assertions to match the real SorobanSimulationResult shape, and fixed two tests reusing a `mockOnce` across two separate calls to the service (second call fell through to the unmocked default and threw on undefined). - transaction.service.spec.ts targeted a pre-broadcast Soroban simulation step that was never wired into TransactionService.create, against a StellarService overload TransactionService doesn't even inject; skipped with an explanation rather than fabricating the feature. - sensitive-rate-limit.integration.spec.ts: replaced Fastify-only `app.inject()` (this app runs on platform-express) with a small http.request helper; the throttler in the test module was unnamed ('default'), so AstroidThrottlerGuard's per-tier name match against the route's default 'api' tier always skipped it — named it 'api' to match. - Removed remaining `any` usages in the touched guard files/specs. - docs/configuration.md: documented THROTTLE_WEBHOOK_LIMIT, THROTTLE_API_BURST, THROTTLE_AUTH_BURST, THROTTLE_WEBHOOK_BURST (missing from #386), failing the configuration-documentation test. --- docs/configuration.md | 162 +++++++++--------- .../sensitive-rate-limit.integration.spec.ts | 72 +++++--- .../sliding-window-throttler.guard.spec.ts | 47 ++++- .../guards/sliding-window-throttler.guard.ts | 39 +++-- src/common/guards/throttler.guard.ts | 15 +- src/events/event-names.ts | 1 - src/modules/agents/agent.controller.ts | 36 +++- src/modules/risk/risk.service.spec.ts | 26 +-- src/modules/risk/risk.service.ts | 36 +++- .../stellar/services/stellar.service.ts | 16 +- .../stellar/tests/stellar.service.spec.ts | 32 ++-- .../tests/transaction.service.spec.ts | 157 ++--------------- 12 files changed, 316 insertions(+), 323 deletions(-) diff --git a/docs/configuration.md b/docs/configuration.md index 7501d188..5d784520 100644 --- a/docs/configuration.md +++ b/docs/configuration.md @@ -44,127 +44,131 @@ guarantees in tests and tools that construct modules without going through These have no default.

Kept the fetch()-based version. - stellar.service.spec.ts: duplicate `error` key in a SorobanSimulationResult object literal. - transaction.service.spec.ts: my placeholder describe.skip stub was prepended to a real, correctly implemented version of the same suite that showed up on main independently.

Make the health controller usable by load balancers: - Mark it @Public(); previously every health route required a JWT. - Exempt it from both named throttler tiers so probes cannot receive 429s. - Exclude it from the audit trail so probes do not write an audit row per request (or attempt to while the database is down). Fix the Redis indicator to probe the shared REDIS_CLIENT built from the validated REDIS_* config. It previously read an undefined REDIS_URL, always probed localhost:6379, kept its own never-closed connection, and could hang while ioredis queued the PING during an outage.

Per-slice validation in each registerAs factory is unchanged, so the typed ConfigService namespaces keep their guarantees outside main.ts. Document every variable, its type, default and production rules in docs/configuration.md, and correct the README's list of required variables. Tests keep the docs and .env.example in sync with the schema, and exercise the real main.ts entrypoint to prove missing or malformed variables halt startup before NestFactory.create is called.

Deleted dead WebhookDeliveryWorker, never registered as a real processor. - Wired the existing, previously unused SlidingWindowThrottlerGuard onto the new public ingress route for Redis-backed sliding-window rate limiting with standard rate-limit headers. - Added StreamMetricsService: ring-buffer based p95/p99 latency aggregation per stream, exposed through the existing Prometheus registry. --- src/common/guards/webhook-signature.guard.ts | 3 +- src/modules/metrics/metrics.module.ts | 21 +- src/modules/metrics/metrics.service.ts | 5 + .../metrics/stream-metrics.service.spec.ts | 98 ++++++ src/modules/metrics/stream-metrics.service.ts | 92 ++++++ .../webhooks/webhook-ingress.controller.ts | 37 +++ src/modules/webhooks/webhook-ingress.dto.ts | 15 + .../webhooks/webhook-ingress.service.ts | 15 + src/modules/webhooks/webhook.module.ts | 22 +- src/modules/webhooks/webhooks.processor.ts | 3 - .../webhooks/workers/webhook.worker.ts | 295 ------------------ src/workers/webhook-delivery.worker.ts | 63 ---- src/workers/worker-shutdown.spec.ts | 6 +- src/workers/workers.module.ts | 3 - 14 files changed, 298 insertions(+), 380 deletions(-) create mode 100644 src/modules/metrics/stream-metrics.service.spec.ts create mode 100644 src/modules/metrics/stream-metrics.service.ts create mode 100644 src/modules/webhooks/webhook-ingress.controller.ts create mode 100644 src/modules/webhooks/webhook-ingress.dto.ts create mode 100644 src/modules/webhooks/webhook-ingress.service.ts delete mode 100644 src/modules/webhooks/workers/webhook.worker.ts delete mode 100644 src/workers/webhook-delivery.worker.ts diff --git a/src/common/guards/webhook-signature.guard.ts b/src/common/guards/webhook-signature.guard.ts index de2db40b..54317966 100644 --- a/src/common/guards/webhook-signature.guard.ts +++ b/src/common/guards/webhook-signature.guard.ts @@ -3,6 +3,7 @@ import { ExecutionContext, Injectable, Logger, + Optional, UnauthorizedException, } from '@nestjs/common';

The destructive commands, down and reset, are rejected when NODE_ENV=production unless --force is supplied. A blocked run prints a warning to stderr, exits with code 1 and never contacts the database. A forced run is also announced on stderr. down runs the migration's hand-written down.sql and removes its _prisma_migrations row in a single script, so the history row is only dropped when every rollback statement succeeded. Migration names are validated against the folder on disk before being used in SQL. The guard logic lives in src/database/migration-guard.ts with injected process dependencies so it is fully unit tested. The entry point src/database/migrate.cli.ts is compiled into dist and can run in images without ts-node. Usage is documented in docs/database.md. --- docs/database.md | 29 ++++ package.json | 3 +- src/database/migrate.cli.ts | 39 +++++ src/database/migration-guard.spec.ts | 240 +++++++++++++++++++++++++++ src/database/migration-guard.ts | 229 +++++++++++++++++++++++++ 5 files changed, 539 insertions(+), 1 deletion(-) create mode 100644 src/database/migrate.cli.ts create mode 100644 src/database/migration-guard.spec.ts create mode 100644 src/database/migration-guard.ts diff --git a/docs/database.md b/docs/database.md index cafccef2..285bce7f 100644 --- a/docs/database.md +++ b/docs/database.md @@ -12,3 +12,32 @@ The API retries PostgreSQL connections during startup using exponential backoff. - Migration directories must start with a 14-digit timestamp prefix (`YYYYMMDDHHMMSS`) to ensure strict ordering and avoid conflicts. - Run `npm run db:verify` locally to execute `scripts/verify-migrations.sh` prior to opening a pull request. - The CI pipeline automatically runs `scripts/verify-migrations.sh` to validate schema syntax, migration structure, and working tree cleanliness. + +## Migration CLI and Rollback Protection + +`npm run db:migrate -- ` wraps the Prisma migration commands behind a production safety guard (`src/database/migration-guard.ts`). + +| Command | Effect | Destructive | +| --- | --- | --- | +| `deploy` | Applies pending migrations (`prisma migrate deploy`). | No | +| `status` | Reports applied and pending migrations. | No | +| `down ` | Executes the migration's `down.sql`, then removes it from `_prisma_migrations` in the same script so `deploy` can re-apply it later. | Yes | +| `reset` | Drops and recreates the database (`prisma migrate reset`). | Yes | + +Destructive commands are **rejected when `NODE_ENV=production`**: the CLI prints a warning to stderr, exits with code `1`, and never contacts the database.

The guards now have 100% statement, branch, function and line coverage. The tests attach real @Roles, @RequirePermissions, @RequireScopes and @Public metadata to fixture controllers and run them through a real Reflector, so handler-over-class inheritance is exercised rather than mocked. Assertion matrices cover every UserRole, every wildcard shape in matchScope, including nested scopes, and the AND semantics of multi- permission routes. Behaviour pinned by these tests: - OWNER bypasses RolesGuard, and a JWT-authenticated OWNER or ADMIN bypasses ScopesGuard; API-key principals with those roles do not. - PermissionsGuard grants no role-based override and expands no wildcards. - Guests and expired or revoked principals, which the auth strategies leave without request.user, get a 401 on every restricted route. - Stale or differently cased role names are rejected. --- src/common/guards/permissions.guard.spec.ts | 127 +++++++++++ src/common/guards/rbac.guard.spec.ts | 25 +++ src/common/guards/roles.guard.spec.ts | 165 ++++++++++++++ src/common/guards/scopes.guard.spec.ts | 233 ++++++++++++++++++++ 4 files changed, 550 insertions(+) create mode 100644 src/common/guards/permissions.guard.spec.ts create mode 100644 src/common/guards/roles.guard.spec.ts create mode 100644 src/common/guards/scopes.guard.spec.ts diff --git a/src/common/guards/permissions.guard.spec.ts b/src/common/guards/permissions.guard.spec.ts new file mode 100644 index 00000000..45eabe5a --- /dev/null +++ b/src/common/guards/permissions.guard.spec.ts @@ -0,0 +1,127 @@ +import { describe, expect, it } from 'vitest'; +import { ExecutionContext } from '@nestjs/common'; +import { Reflector } from '@nestjs/core'; +import { UserRole } from '@prisma/client'; +import { PermissionsGuard } from './permissions.guard'; +import { Permissions, RequirePermissions } from '../decorators/permissions.decorator'; +import { AuthenticatedUser } from '../interfaces/authenticated-user.interface'; +import { ForbiddenException, UnauthorizedException } from '../exceptions/domain.exception'; + +@RequirePermissions('reports:read') +class ReportsController { + inheritsClass() {} + + @RequirePermissions('reports:write', 'reports:publish') + requiresBoth() {} + + @Permissions('reports:export') + viaAlias() {} + + @RequirePermissions() + emptyHandler() {} +} + +class OpenController { + unrestricted() {} +} + +function user(permissions?: string[], role: UserRole = UserRole.VIEWER): AuthenticatedUser { + return { id: 'u-1', organizationId: 'org-1', role, permissions }; +} + +function context( + cls: new () => object, + handler: string, + principal?: AuthenticatedUser, +): ExecutionContext { + const target = cls.prototype as Record void>; + return { + getHandler: () => target[handler], + getClass: () => cls, + switchToHttp: () => ({ getRequest: () => ({ user: principal }) }), + } as unknown as ExecutionContext; +} + +describe('PermissionsGuard', () => { + const guard = new PermissionsGuard(new Reflector()); + + describe('routes without permission metadata', () => { + it('allows a guest', () => { + expect(guard.canActivate(context(OpenController, 'unrestricted'))).toBe(true); + }); + + it('treats an empty handler requirement as no restriction, overriding the class', () => { + expect(guard.canActivate(context(ReportsController, 'emptyHandler', user([])))).toBe(true); + }); + }); + + describe('guest access', () => { + it('rejects an unauthenticated request with 401', () => { + expect(() => guard.canActivate(context(ReportsController, 'inheritsClass'))).toThrow( + UnauthorizedException, + ); + }); + }); + + describe('permission matrix', () => { + /** [granted permissions, route, expected to pass] */ + const matrix: Array<[string[] | undefined, string, boolean]> = [ + [['reports:read'], 'inheritsClass', true], + [['reports:read', 'extra'], 'inheritsClass', true], + [['reports:write'], 'inheritsClass', false], + [['reports:write', 'reports:publish'], 'requiresBoth', true], + [['reports:publish', 'reports:write', 'reports:read'], 'requiresBoth', true], + [['reports:write'], 'requiresBoth', false], + [['reports:read'], 'requiresBoth', false], + [['reports:export'], 'viaAlias', true], + [['reports:read'], 'viaAlias', false], + [[], 'inheritsClass', false], + [undefined, 'inheritsClass', false], + ]; + + it.each(matrix)('granted %j on %s -> %s', (granted, handler, allowed) => { + const run = () => guard.canActivate(context(ReportsController, handler, user(granted))); + if (allowed) { + expect(run()).toBe(true); + } else { + expect(run).toThrow(ForbiddenException); + } + }); + }); + + describe('standard user restrictions', () => { + it('requires every listed permission and names them all in the 403 message', () => { + expect(() => + guard.canActivate(context(ReportsController, 'requiresBoth', user(['reports:write']))), + ).toThrow('Missing required permissions.

Postgres therefore had to fetch all of a tenant's or user's rows, or walk the global createdAt index and filter, before it could return a page.

Batches the 3 counts and 2 aggregates into a single $transaction([...]) call; the 2 groupBy calls stay outside the batch since Prisma's groupBy return type doesn't infer correctly inside a $transaction array. Response shape is unchanged. Existing indexes on organizationId/status/createdAt already cover these queries. * test(audit): cover pagination and sorting edge cases for activity log Closes #339 The audit log (this repo's activity log) already supported page/limit/sort/order/filter query params and returned pagination metadata (total, totalPages, hasNext, hasPrev), with limit capped at 100. Adds unit test coverage for the previously-untested list() method: normal pagination, empty results, out-of-bounds pages, invalid sort field fallback, ascending order, and entity filtering. * fix(migrations): resolve colliding timestamp between two merged migrations Migrations 20260928120000_add_agent_contribution_stats_index and 20260928120000_add_notifications_user_created_at_index landed with the same 14-digit timestamp prefix from two separately merged PRs (#374, #357), which scripts/verify-migrations.sh rejects as a conflict. Bumps the notifications index migration to 20260928120001; both migrations are independent, additive CREATE INDEX statements with no ordering dependency between them, so the rename is safe. * fix(ci): document missing env vars and fix flaky retry.util test Two pre-existing, unrelated-to-this-PR CI failures fixed while unblocking this branch: - docs/configuration.md was missing 7 env vars added by recent merges (DATABASE_SLOW_QUERY_THRESHOLD_MS, DATABASE_CONNECT_RETRY_ATTEMPTS, DATABASE_CONNECT_RETRY_DELAY_MS, PUBLIC_RATE_LIMIT_*), which env.validation.spec.ts asserts against. Documented all 7. - retry.util.spec.ts had 3 tests that create a rejecting promise, advance fake timers with vi.runAllTimersAsync(), then attach the rejection assertion afterward — a race that surfaces as an unhandled rejection under full-suite load (deterministic once >100 files run together). Attaching a no-op .catch() immediately after creating the promise prevents the unhandled state without changing what each test asserts. --- docs/configuration.md | 7 ++ .../migration.sql | 0 src/modules/analytics/analytics.repository.ts | 79 ++++++++-------- .../analytics/analytics.service.spec.ts | 80 ++++++++++++++++ src/modules/analytics/analytics.service.ts | 12 +-- src/modules/audit/audit.service.spec.ts | 91 +++++++++++++++++-- src/utils/retry.util.spec.ts | 3 + 7 files changed, 219 insertions(+), 53 deletions(-) rename prisma/migrations/{20260928120000_add_notifications_user_created_at_index => 20260928120001_add_notifications_user_created_at_index}/migration.sql (100%) create mode 100644 src/modules/analytics/analytics.service.spec.ts diff --git a/docs/configuration.md b/docs/configuration.md index b1c2243a..7501d188 100644 --- a/docs/configuration.md +++ b/docs/configuration.md @@ -84,6 +84,9 @@ are rejected: | `DATABASE_QUERY_TIMEOUT_MS` | `5000` | Client-side query timeout for the API pool. `0` disables it. | | `DATABASE_STATEMENT_TIMEOUT_MS` | `10000` | Server-side `statement_timeout`. `0` disables it. | | `DATABASE_WORKER_QUERY_TIMEOUT_MS` | `60000` | Client-side query timeout for the worker pool. `0` disables it. | +| `DATABASE_SLOW_QUERY_THRESHOLD_MS` | `1000` | Queries slower than this are logged as slow queries. | +| `DATABASE_CONNECT_RETRY_ATTEMPTS` | `5` | Connection attempts before giving up on startup. | +| `DATABASE_CONNECT_RETRY_DELAY_MS` | `1000` | Delay between connection retry attempts. | ### Redis @@ -140,6 +143,10 @@ are rejected: | `THROTTLE_TTL` | `60` | Throttler window in seconds. | | `RATE_LIMIT_WINDOW_SECONDS` | `60` | Sliding-window size for the Redis rate-limiter guard. | | `RATE_LIMIT_MAX_REQUESTS` | `120` | Requests allowed per client per sliding window. | +| `PUBLIC_RATE_LIMIT_ENABLED` | `true` | Enables the IP-based limiter for unauthenticated (`@Public()`) routes. | +| `PUBLIC_RATE_LIMIT_MAX_REQUESTS` | `60` | Requests allowed per client IP per sliding window on public routes. | +| `PUBLIC_RATE_LIMIT_WINDOW_SECONDS` | `60` | Sliding-window size for the public-route rate limiter. | +| `PUBLIC_RATE_LIMIT_TRUST_PROXY` | `false` | Reads client IP from `X-Forwarded-For`.

charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: merge PR #284 — add RiskRepository, RiskAssessment schema, and test files Resolves the merge conflict from PR #284 by applying all genuinely new additions (RiskRepository, schema migration, test specs, service updates) while keeping main's already-improved Swagger DTO implementations. Co-Authored-By: Claude Sonnet 4.6 Claude-Session: https://claude.ai/code/session_012xRrTYwEy2y8yow4o8iUQ8 * fix: use ZodValidationException in integration spec The pipe throws ZodValidationException (a BadRequestException subclass defined in zod-validation.pipe.ts), not the domain-layer ValidationException.

Make the health controller usable by load balancers: - Mark it @Public(); previously every health route required a JWT. - Exempt it from both named throttler tiers so probes cannot receive 429s. - Exclude it from the audit trail so probes do not write an audit row per request (or attempt to while the database is down). Fix the Redis indicator to probe the shared REDIS_CLIENT built from the validated REDIS_* config. It previously read an undefined REDIS_URL, always probed localhost:6379, kept its own never-closed connection, and could hang while ioredis queued the PING during an outage.

Per-slice validation in each registerAs factory is unchanged, so the typed ConfigService namespaces keep their guarantees outside main.ts. Document every variable, its type, default and production rules in docs/configuration.md, and correct the README's list of required variables. Tests keep the docs and .env.example in sync with the schema, and exercise the real main.ts entrypoint to prove missing or malformed variables halt startup before NestFactory.create is called.

Deleted dead WebhookDeliveryWorker, never registered as a real processor. - Wired the existing, previously unused SlidingWindowThrottlerGuard onto the new public ingress route for Redis-backed sliding-window rate limiting with standard rate-limit headers. - Added StreamMetricsService: ring-buffer based p95/p99 latency aggregation per stream, exposed through the existing Prometheus registry. --- src/common/guards/webhook-signature.guard.ts | 3 +- src/modules/metrics/metrics.module.ts | 21 +- src/modules/metrics/metrics.service.ts | 5 + .../metrics/stream-metrics.service.spec.ts | 98 +++++++ src/modules/metrics/stream-metrics.service.ts | 92 +++++++ .../webhooks/webhook-ingress.controller.ts | 37 +++ src/modules/webhooks/webhook-ingress.dto.ts | 15 + .../webhooks/webhook-ingress.service.ts | 15 + src/modules/webhooks/webhook.module.ts | 22 +- src/modules/webhooks/webhooks.processor.ts | 3 - .../webhooks/workers/webhook.worker.ts | 257 ------------------ src/workers/webhook-delivery.worker.ts | 63 ----- src/workers/worker-shutdown.spec.ts | 6 +- src/workers/workers.module.ts | 3 - 14 files changed, 298 insertions(+), 342 deletions(-) create mode 100644 src/modules/metrics/stream-metrics.service.spec.ts create mode 100644 src/modules/metrics/stream-metrics.service.ts create mode 100644 src/modules/webhooks/webhook-ingress.controller.ts create mode 100644 src/modules/webhooks/webhook-ingress.dto.ts create mode 100644 src/modules/webhooks/webhook-ingress.service.ts delete mode 100644 src/modules/webhooks/workers/webhook.worker.ts delete mode 100644 src/workers/webhook-delivery.worker.ts diff --git a/src/common/guards/webhook-signature.guard.ts b/src/common/guards/webhook-signature.guard.ts index de2db40b..54317966 100644 --- a/src/common/guards/webhook-signature.guard.ts +++ b/src/common/guards/webhook-signature.guard.ts @@ -3,6 +3,7 @@ import { ExecutionContext, Injectable, Logger, + Optional, UnauthorizedException, } from '@nestjs/common';

The destructive commands, down and reset, are rejected when NODE_ENV=production unless --force is supplied. A blocked run prints a warning to stderr, exits with code 1 and never contacts the database. A forced run is also announced on stderr. down runs the migration's hand-written down.sql and removes its _prisma_migrations row in a single script, so the history row is only dropped when every rollback statement succeeded. Migration names are validated against the folder on disk before being used in SQL. The guard logic lives in src/database/migration-guard.ts with injected process dependencies so it is fully unit tested. The entry point src/database/migrate.cli.ts is compiled into dist and can run in images without ts-node.

The guards now have 100% statement, branch, function and line coverage. The tests attach real @Roles, @RequirePermissions, @RequireScopes and @Public metadata to fixture controllers and run them through a real Reflector, so handler-over-class inheritance is exercised rather than mocked. Assertion matrices cover every UserRole, every wildcard shape in matchScope, including nested scopes, and the AND semantics of multi- permission routes. Behaviour pinned by these tests: - OWNER bypasses RolesGuard, and a JWT-authenticated OWNER or ADMIN bypasses ScopesGuard; API-key principals with those roles do not. - PermissionsGuard grants no role-based override and expands no wildcards. - Guests and expired or revoked principals, which the auth strategies leave without request.user, get a 401 on every restricted route. - Stale or differently cased role names are rejected. --- src/common/guards/permissions.guard.spec.ts | 127 +++++++++++ src/common/guards/rbac.guard.spec.ts | 25 +++ src/common/guards/roles.guard.spec.ts | 165 ++++++++++++++ src/common/guards/scopes.guard.spec.ts | 233 ++++++++++++++++++++ 4 files changed, 550 insertions(+) create mode 100644 src/common/guards/permissions.guard.spec.ts create mode 100644 src/common/guards/roles.guard.spec.ts create mode 100644 src/common/guards/scopes.guard.spec.ts diff --git a/src/common/guards/permissions.guard.spec.ts b/src/common/guards/permissions.guard.spec.ts new file mode 100644 index 00000000..45eabe5a --- /dev/null +++ b/src/common/guards/permissions.guard.spec.ts @@ -0,0 +1,127 @@ +import { describe, expect, it } from 'vitest'; +import { ExecutionContext } from '@nestjs/common'; +import { Reflector } from '@nestjs/core'; +import { UserRole } from '@prisma/client'; +import { PermissionsGuard } from './permissions.guard'; +import { Permissions, RequirePermissions } from '../decorators/permissions.decorator'; +import { AuthenticatedUser } from '../interfaces/authenticated-user.interface'; +import { ForbiddenException, UnauthorizedException } from '../exceptions/domain.exception'; + +@RequirePermissions('reports:read') +class ReportsController { + inheritsClass() {} + + @RequirePermissions('reports:write', 'reports:publish') + requiresBoth() {} + + @Permissions('reports:export') + viaAlias() {} + + @RequirePermissions() + emptyHandler() {} +} + +class OpenController { + unrestricted() {} +} + +function user(permissions?: string[], role: UserRole = UserRole.VIEWER): AuthenticatedUser { + return { id: 'u-1', organizationId: 'org-1', role, permissions }; +} + +function context( + cls: new () => object, + handler: string, + principal?: AuthenticatedUser, +): ExecutionContext { + const target = cls.prototype as Record void>; + return { + getHandler: () => target[handler], + getClass: () => cls, + switchToHttp: () => ({ getRequest: () => ({ user: principal }) }), + } as unknown as ExecutionContext; +} + +describe('PermissionsGuard', () => { + const guard = new PermissionsGuard(new Reflector()); + + describe('routes without permission metadata', () => { + it('allows a guest', () => { + expect(guard.canActivate(context(OpenController, 'unrestricted'))).toBe(true); + }); + + it('treats an empty handler requirement as no restriction, overriding the class', () => { + expect(guard.canActivate(context(ReportsController, 'emptyHandler', user([])))).toBe(true); + }); + }); + + describe('guest access', () => { + it('rejects an unauthenticated request with 401', () => { + expect(() => guard.canActivate(context(ReportsController, 'inheritsClass'))).toThrow( + UnauthorizedException, + ); + }); + }); + + describe('permission matrix', () => { + /** [granted permissions, route, expected to pass] */ + const matrix: Array<[string[] | undefined, string, boolean]> = [ + [['reports:read'], 'inheritsClass', true], + [['reports:read', 'extra'], 'inheritsClass', true], + [['reports:write'], 'inheritsClass', false], + [['reports:write', 'reports:publish'], 'requiresBoth', true], + [['reports:publish', 'reports:write', 'reports:read'], 'requiresBoth', true], + [['reports:write'], 'requiresBoth', false], + [['reports:read'], 'requiresBoth', false], + [['reports:export'], 'viaAlias', true], + [['reports:read'], 'viaAlias', false], + [[], 'inheritsClass', false], + [undefined, 'inheritsClass', false], + ]; + + it.each(matrix)('granted %j on %s -> %s', (granted, handler, allowed) => { + const run = () => guard.canActivate(context(ReportsController, handler, user(granted))); + if (allowed) { + expect(run()).toBe(true); + } else { + expect(run).toThrow(ForbiddenException); + } + }); + }); + + describe('standard user restrictions', () => { + it('requires every listed permission and names them all in the 403 message', () => { + expect(() => + guard.canActivate(context(ReportsController, 'requiresBoth', user(['reports:write']))), + ).toThrow('Missing required permissions.

Postgres therefore had to fetch all of a tenant's or user's rows, or walk the global createdAt index and filter, before it could return a page. These composite indexes match the actual query shapes: - notifications (userId, createdAt): inbox list - notifications (organizationId, userId, read, createdAt): unread badge, mark-all-read, unread filter (index-only count) - proposals (organizationId, createdAt): approval queue - proposals (organizationId, status, createdAt): pending count, status filter - memory_records (organizationId, createdAt): memory browser - memory_records (agentId, createdAt): per-agent memory timeline Each index is built with CREATE INDEX CONCURRENTLY, so writes are never blocked. Each one lives in its own single-statement migration, because Prisma runs a multi-statement migration as one implicit transaction, where Postgres rejects CONCURRENTLY. The matching @@index entries are added to schema.prisma so migrate dev reports no drift. docs/concurrent-indexes.md records the convention and how to recover from a failed concurrent build. --- docs/concurrent-indexes.md | 38 +++++++++++++++++++ .../migration.sql | 9 +++++ .../migration.sql | 11 ++++++ .../migration.sql | 8 ++++ .../migration.sql | 9 +++++ .../migration.sql | 8 ++++ .../migration.sql | 8 ++++ prisma/schema.prisma | 6 +++ 8 files changed, 97 insertions(+) create mode 100644 docs/concurrent-indexes.md create mode 100644 prisma/migrations/20260928120000_add_notifications_user_created_at_index/migration.sql create mode 100644 prisma/migrations/20260928120100_add_notifications_org_user_read_created_at_index/migration.sql create mode 100644 prisma/migrations/20260928120200_add_proposals_org_created_at_index/migration.sql create mode 100644 prisma/migrations/20260928120300_add_proposals_org_status_created_at_index/migration.sql create mode 100644 prisma/migrations/20260928120400_add_memory_records_org_created_at_index/migration.sql create mode 100644 prisma/migrations/20260928120500_add_memory_records_agent_created_at_index/migration.sql diff --git a/docs/concurrent-indexes.md b/docs/concurrent-indexes.md new file mode 100644 index 00000000..4436749b --- /dev/null +++ b/docs/concurrent-indexes.md @@ -0,0 +1,38 @@ +# Adding Indexes Without Downtime + +Indexes on live tables are created with `CREATE INDEX CONCURRENTLY`, so writes to the table are never blocked while the index builds. + +## Rules + +1. **One statement per migration.** Postgres refuses `CONCURRENTLY` inside a transaction block, and Prisma sends a multi-statement `migration.sql` as a single implicit transaction.

Batches the 3 counts and 2 aggregates into a single $transaction([...]) call; the 2 groupBy calls stay outside the batch since Prisma's groupBy return type doesn't infer correctly inside a $transaction array. Response shape is unchanged. Existing indexes on organizationId/status/createdAt already cover these queries. * test(audit): cover pagination and sorting edge cases for activity log Closes #339 The audit log (this repo's activity log) already supported page/limit/sort/order/filter query params and returned pagination metadata (total, totalPages, hasNext, hasPrev), with limit capped at 100. Adds unit test coverage for the previously-untested list() method: normal pagination, empty results, out-of-bounds pages, invalid sort field fallback, ascending order, and entity filtering. * fix(migrations): resolve colliding timestamp between two merged migrations Migrations 20260928120000_add_agent_contribution_stats_index and 20260928120000_add_notifications_user_created_at_index landed with the same 14-digit timestamp prefix from two separately merged PRs (#374, #357), which scripts/verify-migrations.sh rejects as a conflict. Bumps the notifications index migration to 20260928120001; both migrations are independent, additive CREATE INDEX statements with no ordering dependency between them, so the rename is safe. * fix(ci): document missing env vars and fix flaky retry.util test Two pre-existing, unrelated-to-this-PR CI failures fixed while unblocking this branch: - docs/configuration.md was missing 7 env vars added by recent merges (DATABASE_SLOW_QUERY_THRESHOLD_MS, DATABASE_CONNECT_RETRY_ATTEMPTS, DATABASE_CONNECT_RETRY_DELAY_MS, PUBLIC_RATE_LIMIT_*), which env.validation.spec.ts asserts against. Documented all 7. - retry.util.spec.ts had 3 tests that create a rejecting promise, advance fake timers with vi.runAllTimersAsync(), then attach the rejection assertion afterward — a race that surfaces as an unhandled rejection under full-suite load (deterministic once >100 files run together). Attaching a no-op .catch() immediately after creating the promise prevents the unhandled state without changing what each test asserts. --- docs/configuration.md | 7 ++ .../migration.sql | 0 src/modules/analytics/analytics.repository.ts | 79 ++++++++-------- .../analytics/analytics.service.spec.ts | 80 ++++++++++++++++ src/modules/analytics/analytics.service.ts | 12 +-- src/modules/audit/audit.service.spec.ts | 91 +++++++++++++++++-- src/utils/retry.util.spec.ts | 3 + 7 files changed, 219 insertions(+), 53 deletions(-) rename prisma/migrations/{20260928120000_add_notifications_user_created_at_index => 20260928120001_add_notifications_user_created_at_index}/migration.sql (100%) create mode 100644 src/modules/analytics/analytics.service.spec.ts diff --git a/docs/configuration.md b/docs/configuration.md index b1c2243a..7501d188 100644 --- a/docs/configuration.md +++ b/docs/configuration.md @@ -84,6 +84,9 @@ are rejected: | `DATABASE_QUERY_TIMEOUT_MS` | `5000` | Client-side query timeout for the API pool. `0` disables it. | | `DATABASE_STATEMENT_TIMEOUT_MS` | `10000` | Server-side `statement_timeout`. `0` disables it. | | `DATABASE_WORKER_QUERY_TIMEOUT_MS` | `60000` | Client-side query timeout for the worker pool. `0` disables it. | +| `DATABASE_SLOW_QUERY_THRESHOLD_MS` | `1000` | Queries slower than this are logged as slow queries. | +| `DATABASE_CONNECT_RETRY_ATTEMPTS` | `5` | Connection attempts before giving up on startup. | +| `DATABASE_CONNECT_RETRY_DELAY_MS` | `1000` | Delay between connection retry attempts. | ### Redis @@ -140,6 +143,10 @@ are rejected: | `THROTTLE_TTL` | `60` | Throttler window in seconds. | | `RATE_LIMIT_WINDOW_SECONDS` | `60` | Sliding-window size for the Redis rate-limiter guard. | | `RATE_LIMIT_MAX_REQUESTS` | `120` | Requests allowed per client per sliding window. | +| `PUBLIC_RATE_LIMIT_ENABLED` | `true` | Enables the IP-based limiter for unauthenticated (`@Public()`) routes. | +| `PUBLIC_RATE_LIMIT_MAX_REQUESTS` | `60` | Requests allowed per client IP per sliding window on public routes. | +| `PUBLIC_RATE_LIMIT_WINDOW_SECONDS` | `60` | Sliding-window size for the public-route rate limiter. | +| `PUBLIC_RATE_LIMIT_TRUST_PROXY` | `false` | Reads client IP from `X-Forwarded-For`.

CI enforces these repo-wide, so they block this PR too. Fixed each: - event-names.ts: duplicate object key (TransactionRiskScoringRequested) - throttler.guard.ts: read AuthenticatedUser.sub, a field that doesn't exist on that type (JWT payload field name leaked into the wrong type) - sliding-window-throttler.guard.ts: removed a user-tier rate-limit multiplier keyed on AuthenticatedUser.tier, a field never present anywhere in the auth/user model — dead, unbacked logic. Removed its now-orphaned tests too. - agent.controller.ts: AstroidThrottlerGuard used but never imported; dropped an unused SlidingWindowThrottlerGuard import block - risk.service.ts: event-driven risk scoring built a RiskFactorsInput with fields (destination/velocityCount/isNewRecipient) that don't exist on the current type; mapped to the real shape instead - risk.service.spec.ts: removed orphaned unused fixtures - stellar.service.ts (src/modules/stellar/services, unused elsewhere in the app but still typechecked/tested): getTransactionInfo called a client method that doesn't exist (real method is getTransaction); simulateTransaction passed a bare string where the client expects an options object - stellar.service.spec.ts: rewritten against the real SorobanSimulationResult shape; fixed mockResolvedValueOnce/ mockRejectedValueOnce being consumed by the test's own first assertion, leaving the second call unmocked - transaction.service.spec.ts: rewritten against TransactionService's actual create() contract (it doesn't call Soroban simulation at all;

charset=UTF-8 Content-Transfer-Encoding: 8bit Every authenticated request performed a Redis round trip against the token blacklist to answer "is this session still revoked?". This adds a short-TTL caching layer in front of the blacklist so repeated verifications within one window skip the Redis query entirely. - Add CacheService: a small get/set/delete cache over the shared REDIS_CLIENT with TTL-bounded entries, JSON payloads, and SCAN-based prefix invalidation. Every operation degrades to a no-op/miss on Redis failure so caching can never break the request path. - Add TokenVerificationCacheService: caches per-session revocation answers for TOKEN_CACHE_TTL seconds (default 30, well below the 15-minute access-token lifetime) and exposes invalidation hooks. - Wire the cache into JwtStrategy.validate (cache-first, source of truth on miss, fail-open unchanged on Redis outages). - Hook invalidation into every revocation path: TokenBlacklistService drops the cached answer after each blacklist write (including on Redis-outage fallback), AuthService invalidates on logout and on refresh rotation, so revocations are observed immediately instead of after the TTL window. Revocation reliability is preserved because no cached answer outlives its TTL, and explicit logout/rotation clears the entry at once. Tests: unit suites for CacheService and TokenVerificationCacheService (hits, misses, resolver fallback, invalidation hooks), an integration suite proving repeated authentications trigger a single blacklist lookup and that logout flips a cached-valid session to 401 immediately, plus updated JwtStrategy/TokenBlacklistService/api-key integration suites for the new wiring.

charset=UTF-8 Content-Transfer-Encoding: 8bit Public endpoints are the first thing abusive traffic hits, but their limits were a single fixed IP budget: every public route shared PUBLIC_RATE_LIMIT_MAX_REQUESTS per window, and all clients behind one shared address (NAT, office egress, CI runners) exhausted one bucket together. This makes the public rate limiter configurable per route and per client identifier, on the existing Redis sliding-window counter. - Add @PublicRateLimit(max, windowSeconds) decorator: per-route (or per-controller) budget overrides resolved by the guard through Reflector; the global PUBLIC_RATE_LIMIT_* settings remain the default. - Add PUBLIC_RATE_LIMIT_CLIENT_IDENTIFIERS (optional, comma-separated, currently 'apiKey'): when enabled, a presented x-api-key or ApiKey/Bearer ak_... Authorization header is folded into the bucket key so distinct key-holding clients behind one IP get their own budgets. The IP always participates; keyless callers share the plain-IP bucket as before. - Extract a testable PublicRateLimitGuard.check() returning the full decision (allowed, limit, windowSeconds, count, resetAt); canActivate keeps its existing 429 + X-RateLimit-Limit/Remaining/Reset + Retry-After contract and in-memory fallback on Redis outage. Tests: unit suites for per-route rule resolution, identifier bucketing (with/without identifiers configured), header correctness on allowed and limited requests, and @SkipPublicRateLimit() interaction with rules; an HTTP-level integration suite simulating bursts that proves the 429-with-headers behaviour at the global limit, per-route overrides (next to unaffected sibling routes), and per-key budget isolation. Existing public-rate-limit suites pass unchanged (bucket keys keep the ip: prefix, so stored counters stay compatible).
