+# Changelog — Secrets-Broker contract
+
+All notable changes to the Identity-Vault Secrets-Broker contract
+(`openapi.yaml` + `mcp-tools.json`) are recorded here. The contract is the
+fan-out gate; every change bumps `info.version` / `package.json` version
+(semver) and ripples to all generated clients through the contract PR.
+
+## [0.1.0] - 2026-06-26
+
+Initial frozen contract — Phase 2 fan-out gate.
+
+### Added
+- OpenAPI 3.1 spec (`openapi.yaml`) for the Secrets-Broker REST API:
+  - Discovery (metadata only): `GET /identities`, `/identities/{id}/site-logins`,
+    `/identities/{id}/api-tokens`.
+  - Policy-gated secret access: `GET /identities/{id}/profile`,
+    `/site-logins/{site}`, `/site-logins/{site}/totp` (current code, never the seed),
+    `/cards/{cardId}` (HIGH -> 202), `/api-tokens/{service}` (HIGH -> 202).
+  - Write: `POST /identities/{id}/site-logins`.
+  - Approval workflow: `GET /approvals/{request_id}` (one-time short-TTL value),
+    `GET /approvals`, `POST /approvals/{request_id}/approve|deny`.
+  - Management CRUD-lite: organizations, organization members, identities, agents,
+    agent scopes, agent token rotation, and `GET /audit-log`.
+  - `components/schemas` for every design Section 5 entity + all request/response
+    bodies; sensitivity tiers (LOW/MEDIUM/HIGH) encoded; HIGH => approval.
+  - `agentBearer` security scheme (hashed agent token, owner + scope enforcement);
+    401/403/404/202 responses reflecting the security model.
+- MCP tool contract (`mcp-tools.json`) for all 10 tools from design Section 6,
+  field-aligned with the REST schemas.
+- Spectral ruleset (`.spectral.yaml`), `package.json` scripts (lint / mock /
+  gen:types), scoped `.npmrc`, and the generated TS types under `client/`.

+# Identity Vault — Secrets-Broker Contract (Phase 2, frozen gate)
+
+This is the **frozen contract** for the FuzeKeys identity-vault Secrets-Broker. Backend, UI,
+and tests are all built against it (see design
+`docs/superpowers/specs/2026-06-24-identity-vault-mcp-design.md`). Changes ripple deliberately:
+amend via PR, don't diverge silently.
+
+## Files
+| File | Purpose |
+|------|---------|
+| `openapi.yaml` | OpenAPI 3.1 REST contract (23 paths, 46 schemas) — the broker implements this |
+| `mcp-tools.json` | MCP tool contract (10 tools) the agent-facing MCP server exposes |
+| `.spectral.yaml` | Spectral lint ruleset for `openapi.yaml` |
+| `package.json` | scripts: `lint`, `mock`, `gen:types` |
+| `client/` | generated TS types (`gen:types` output; consumed by UI/tests) |
+
+## MCP tool ↔ REST endpoint mapping
+| MCP tool | REST endpoint | Tier |
+|----------|---------------|------|
+| `list_identities` | `GET /identities` | metadata |
+| `list_site_logins` | `GET /identities/{id}/site-logins` | metadata |
+| `list_api_tokens` | `GET /identities/{id}/api-tokens` | metadata |
+| `get_identity_profile` | `GET /identities/{id}/profile` | LOW auto · SSN/passport → approval |
+| `get_site_login` | `GET /identities/{id}/site-logins/{site}` | MEDIUM (auto in-scope) |
+| `get_totp_code` | `GET /identities/{id}/site-logins/{site}/totp` | MEDIUM — returns the **current code, never the seed** |
+| `get_card` | `GET /identities/{id}/cards/{cardId}` | HIGH → approval |
+| `get_api_token` | `GET /identities/{id}/api-tokens/{service}` | HIGH → approval |
+| `store_site_login` | `POST /identities/{id}/site-logins` | write (policy-gated, audited) |
+| `check_approval` | `GET /approvals/{request_id}` | — |
+
+## Sensitivity & approval semantics
+- **LOW** (metadata, display name) and **MEDIUM** (site password, TOTP code) release automatically
+  *when in scope*, and are audited.
+- **HIGH** (cards, API tokens, SSN/passport) return **HTTP 202** `{status:"approval_required",
+  request_id, expires_at}`. The agent polls `GET /approvals/{request_id}`; once a human approves
+  (in-app / Telegram / Slack / email), it returns a **one-time, short-TTL** value. Denied/expired
+  requests never release.
+
+## Security model (encoded in the spec)
+- Agent auth: **bearer token** (`securitySchemes`), bound to a user + scope.
+- The broker's scope check is the tenant boundary (single Vaultwarden silo): `401` bad/missing
+  token, `403` out-of-scope / cross-tenant, `404` not found under the supplied owner, `202`
+  approval required. No endpoint returns a secret without passing policy + writing an audit record.
+
+## Consuming the contract
+```bash
+cd contracts/identity-vault
+npm install              # spectral, prism, openapi-typescript (see package.json)
+npm run lint             # spectral lint openapi.yaml
+npm run mock             # prism mock server — UI/tests build against this, no backend needed
+npm run gen:types        # openapi-typescript -> client/types.ts (shared types for UI/tests)
+```
+The backend implements `openapi.yaml`; the independent test suite asserts against the **same**
+spec, so contract drift becomes a failure.
+
+## Status
+**Frozen** as the Phase 2 fan-out gate. Phases 3–5 (vault infra, broker, approval UI) build
+against this. Validated: `openapi.yaml` and `mcp-tools.json` parse; field names/types are
+consistent between the REST schemas and the MCP tool I/O.
