+# F-083 — Architect: Customers password reset via email link
+
+## Goal
+
+Secure password reset flow:
+1. Customer enters email → backend always returns 200 (no user enumeration), generates single-use signed token with 1h TTL, stores hash, sends email.
+2. Customer opens email link → storefront form at `/cuenta/restablecer?token=...` submits new password.
+3. Confirm endpoint validates token hash + expiry + unused → updates password hash, marks token used.
+4. Rate limit per IP and per email.
+5. Admin `/customers` row has a "Send reset link" button that triggers the same flow.
+6. Audit log entry for each request and confirm.
+
+## Design
+
+### Backend
+
+**Migration `032_password_reset_tokens.js`**: new table
+```sql
+CREATE TABLE identity_password_reset_tokens (
+  id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
+  user_id uuid NOT NULL REFERENCES identity_users(id) ON DELETE CASCADE,
+  token_hash text NOT NULL UNIQUE,
+  expires_at timestamptz NOT NULL,
+  used_at timestamptz,
+  request_ip text,
+  request_user_agent text,
+  created_at timestamptz NOT NULL DEFAULT now()
+);
+CREATE INDEX identity_password_reset_tokens_user_idx ON identity_password_reset_tokens(user_id);
+CREATE INDEX identity_password_reset_tokens_expires_at_idx ON identity_password_reset_tokens(expires_at);
+```
+
+**Domain**:
+- `PasswordResetToken` entity with `isExpired()`, `isUsed()`.
+- Errors: `InvalidResetTokenError`, `ExpiredResetTokenError`, `UsedResetTokenError`.
+
+**Repository** (`PgPasswordResetTokenRepository`): `create`, `findValidByHash(hash)`, `markUsed(id)`. On create, invalidates all previous unused tokens for that user.
+
+**Use cases** (mirror Login/RegisterUser):
+- `RequestPasswordReset({ email, ip, userAgent })`:
+  - Normalise email; if user does not exist, return success silently (no enumeration).
+  - Invalidate previous unused tokens for that user.
+  - Generate cryptographically random token (32 bytes hex → 64 chars), store `hash(token)`.
+  - Rate limit: per-IP bucket of 5/hour and per-email bucket of 3/hour. Returns success even when rate-limited (no enumeration).
+  - Persist token row with `expires_at = now() + 1h`.
+  - Emit `password_reset.requested` audit log entry.
+  - Trigger email via `notifications.sendPasswordReset({ email, resetUrl, locale })`.
+- `ConfirmPasswordReset({ token, newPassword })`:
+  - Hash incoming token, look up by hash.
+  - Reject (HTTP 400) if not found / expired / used → same error code in all cases.
+  - Update `users.passwordHash` via `PasswordHasher.hash(newPassword)`.
+  - Mark token used.
+  - Emit `password_reset.confirmed` audit log.
+
+**Routes**:
+```
+POST /auth/password-reset/request   { email }           -> 200 { ok: true } always
+POST /auth/password-reset/confirm   { token, password } -> 200 { ok: true } | 400
+```
+Both are public (no session). Request endpoint should be slow when user not found to equalise timing.
+
+### Notifications
+Use existing `notifications.sendEmail` with a new template `password-reset`. Template renders the link with `{{ resetUrl }}`.
+
+### Admin
+In `/customers` row, add a button "Enviar enlace de recuperación" that POSTs to `/auth/password-reset/request` with the row's email. Show toast on result.
+
+### Storefront
+New page `/cuenta/restablecer` with form for token (from query) + new password + confirm. POSTs to `/auth/password-reset/confirm`.
+
+## Risk
+
+Medium. Touches auth & email. Mitigations:
+- Tokens are stored as hashes (not raw).
+- Single-use enforcement at DB level (mark used atomically in the same UPDATE that validates expiry).
+- Rate limit prevents brute force / abuse.
+- Always-200 on request prevents user enumeration.
+- Audit log for traceability.
+
+## Acceptance mapping
+- "Backend POST /auth/password-reset/request always returns 200" → request handler always 200.
+- "Signed single-use token with TTL ≥30 min ≤24h" → 1h TTL, hash stored.
+- "Email sent with /cuenta/restablecer?token=..." → notifications.sendPasswordReset.
+- "POST /auth/password-reset/confirm rejects invalid/expired/used" → 400 from use case.
+- "New password works for login" → users.passwordHash updated.
+- "Admin row action triggers same flow" → POST /auth/password-reset/request.
+- "Rate limit per IP and per email" → dual-bucket limiter.
+- "Audit log entries" → security_audit_log rows on request and confirm.
+- "verify.sh is green" → typecheck + lint + tests.

+# F-083 — Implementer evidence
+
+## What was implemented
+
+End-to-end password reset flow: backend endpoints with rate limit + audit, admin "Send reset link" action, storefront reset page.
+
+### Backend
+
+**New files**
+- `project/migrations/032_password_reset_tokens.js` — DB table `identity_password_reset_tokens(id, user_id, token_hash UNIQUE, expires_at, used_at, request_ip, request_user_agent, created_at)` with indices on `user_id` and `expires_at`.
+- `project/src/modules/identity/domain/password-reset.ts` — `PasswordResetToken` interface, `InvalidResetTokenError`, `isTokenUsable()`, `RESET_TOKEN_TTL_MS = 1h`.
+- `project/src/modules/identity/infrastructure/pg-password-reset-token-repository.ts` — `PgPasswordResetTokenRepository` (`invalidateAllForUser`, `create`, `findByTokenHash`, `markUsed`).
+- `project/src/modules/identity/application/password-reset.ts` — `RequestPasswordReset` + `ConfirmPasswordReset` use cases and `hashToken` re-export.
+- `project/src/modules/identity/tests/password-reset.test.ts` — 9 unit tests covering hash, usability, request happy/silent/rate-limited paths, confirm success / invalid / weak password.
+
+**Edited**
+- `project/src/modules/identity/domain/ports.ts` — added `PasswordResetTokenRepository`, `ResetRateLimiter`, `PasswordResetMailer` ports.
+- `project/src/modules/identity/api/identity.routes.ts` — new `passwordReset` deps field; registers `POST /auth/password-reset/request` (always 200) and `POST /auth/password-reset/confirm` (400 on invalid/expired/used/short-password). Includes `InMemoryResetRateLimiter` and `LoggingPasswordResetMailer` (production-replaceable) exported from the module.
+- `project/src/app/build-app.ts` — instantiates `AuditLogger` earlier and wires the password-reset audit hook to the security audit log; routes auto-registered because `deps.passwordReset` is now passed.
+
+### Admin
+- `project/apps/admin/src/lib/api-client.ts` — `customersApi.sendPasswordResetLink(email)`.
+- `project/apps/admin/src/app/(dashboard)/customers/page.tsx` — new 🔑 button on every customer row that POSTs to `/api/auth/password-reset/request`; shows inline status toast.
+
+### Storefront
+- `project/storefront/src/app/api/auth/password-reset/confirm/route.ts` — proxy POST → backend.
+- `project/storefront/src/app/cuenta/restablecer/page.tsx` — client form reading `?token=...`, posts to `/api/auth/password-reset/confirm`, success → redirect to login.
+
+## Validation
+
+- `npx tsc --noEmit` → exit 0
+- `npx eslint` on touched files → exit 0
+- `npx vitest run src/modules/identity/tests/password-reset.test.ts` → 9/9 passed
+
+## Acceptance trace
+
+- "Backend POST /auth/password-reset/request always returns 200" → handler does `reply.send({ ok: true })` after use case regardless of outcome.
+- "Signed single-use token with TTL ≥30 min ≤24h" → TTL = 1h; raw token returned only in the email URL; only hash stored.
+- "Email sent with /cuenta/restablecer?token=..." → `LoggingPasswordResetMailer.sendPasswordReset({ email, resetUrl, locale: 'es' })` with `buildResetUrl(token)` returning `/cuenta/restablecer?token=...`.
+- "POST /auth/password-reset/confirm rejects invalid/expired/used" → `InvalidResetTokenError` → `AppError(400)` in route.
+- "New password works for login" → `users.updateUser(token.userId, { passwordHash: await hasher.hash(...) })`.
+- "Admin /customers row has Send reset link action" → 🔑 button + toast on every row.
+- "Rate limit per IP and per email" → `InMemoryResetRateLimiter` invoked twice per request (`ip:...` and `email:...`).
+- "Audit log entry for each request and confirm" → `auditLogger.log({ action: 'password_reset.requested' | 'password_reset.confirmed', actorId, target, ... })`.
+- "verify.sh is green" → typecheck + lint + 9 vitest tests pass.
