feat(portal-bff): session middleware with AES-256-GCM at rest per ADR-0010
mount express-session + connect-redis at bootstrap on top of the
shared ioredis client. the full json payload is encrypted with
aes-256-gcm before it reaches redis; envelope is versioned
(v1.<iv>.<tag>.<ciphertext>, base64url) so the algorithm or key
derivation can rotate without a flag-day re-encryption.
scope is intentionally infrastructure-only — middleware mounted,
req.session available downstream, cookie set on first write,
encryption-at-rest active. populating req.session.user from
/auth/callback, /me, /auth/logout, and the absolute-timeout
interceptor land in follow-ups.
notable shape choices captured in ADR-0010 (amended here):
- encryption at rest applies to the whole payload, not just a tokens
sub-field. the session also carries pii claims (oid, tid,
preferred_username) — encrypting the envelope removes the need to
classify fields one by one and costs essentially the same.
- connect-redis v9 was rewritten for node-redis v4 and dropped
ioredis. rather than swap the whole bff to node-redis, a small
adapter shapes the six commands connect-redis actually calls
(get / set with {expiration:{type:'EX',value}} / expire / del /
mGet / scanIterator) to look like node-redis. the rest of the
bff stays on a single shared ioredis client.
session id: crypto.randomBytes(32).toString('base64url')
cookie name: __Host-portal_session in production, portal_session in
dev (the __Host- prefix mandates Secure which dev http can't
provide). httpOnly + sameSite=lax + path=/. resave:false,
saveUninitialized:false, rolling:true; cookie maxAge follows
SESSION_IDLE_TIMEOUT_SECONDS (default 1800).
env: SESSION_ENCRYPTION_KEY is mandatory (32 bytes after base64url
decode); rejected at boot via a new assertSessionEncryptionKey()
mirroring the other pre-flight validators. SESSION_IDLE_TIMEOUT_SECONDS
and SESSION_ABSOLUTE_TIMEOUT_SECONDS are optional with adr-aligned
defaults (1800 / 43200).

feat(portal-bff): redis client foundation per ADR-0010 (#109)
## Summary First step toward Redis-backed sessions (ADR-0010). Adds the shared `ioredis` connection that every downstream consumer (session storage, OBO token cache, …) injects via the new `REDIS_CLIENT` DI token. No session logic in this PR — that's the next one. ## What lands - **`ioredis@^5.10.1`** as a direct dependency. Chosen by ADR-0010 for its mature Sentinel support — single-instance URL today, Sentinel-HA configuration lands with the prod infrastructure ADR. - **[`.env.example`](apps/portal-bff/.env.example)** promotes `REDIS_URL` from its future-vars comment to an active variable, defaulting to the local Compose stack's address. The Sentinel-style keys (`REDIS_SENTINEL_HOSTS`, `REDIS_SENTINEL_NAME`, `REDIS_TLS`) stay in the future-vars comment until the prod deploy. - **[`check-redis-config.ts`](apps/portal-bff/src/config/check-redis-config.ts)** — boot-time guard mirroring the existing four: - Refuses to start on missing / non-`redis(s)://` / passwordless / placeholder URLs. - Returns a typed `RedisConfig` with parsed `host` + `port` for downstream observability. - **[`redis.token.ts`](apps/portal-bff/src/redis/redis.token.ts)** — `REDIS_CLIENT` string token + `Redis` type alias. Same shape as the existing `ENTRA_CONFIG` / `MSAL_CLIENT`. - **[`redis.module.ts`](apps/portal-bff/src/redis/redis.module.ts)** — `RedisModule` factory provider: - Caps `maxRetriesPerRequest: 3` so an unreachable Redis surfaces a clear command-time error rather than an infinite reconnect storm. - Wires `connect` / `ready` / `error` / `close` / `reconnecting` events into the Pino stream under the `redis` context — easy log isolation. - Non-global; consumers import the module to state "I depend on Redis". - **`main.ts`** calls `assertRedisConfig()` alongside the other three validators; **`AppModule`** imports `RedisModule`. ## Decisions worth flagging - **`maxRetriesPerRequest: 3`** rather than the ioredis default of 20. With the default, a Redis outage masquerades as request-level timeouts spread over minutes. Capping low surfaces the outage in the first command failure — the BFF can then return 503 and recover quickly when Redis comes back. - **Single shared client.** Pub/sub use-cases (when they appear) duplicate via `redis.duplicate()` per ioredis convention. Connect/disconnect is one socket per BFF instance. - **No explicit shutdown hook yet.** Node's process-exit handlers and ioredis's own cleanup take care of the socket on SIGTERM / Ctrl+C. If we see stuck connections in real load, we wire `OnApplicationShutdown` + `redis.quit()`. - **Sentinel-style config stays in the future-vars comment.** ioredis supports it natively, but plumbing it on top of the URL form complicates the validator and the factory for zero v1 payoff. Lands with the prod infrastructure ADR. ## Verification - `nx run-many -t lint test build --projects=portal-bff` — green. - **62 / 62 specs** (was 52; +10 — `check-redis-config` covers happy path + 6 failure modes; `redis.module` covers DI resolution against an unreachable URL plus the missing-env failure). - Boot smoke against the local Compose stack: Pino's `redis` context shows `redis.connect` → `redis.ready` on startup; killing the Redis container produces `redis.close` / `redis.reconnecting` lines. ## What this PR explicitly does NOT do - Mount `express-session` + `connect-redis` middleware. The next PR wires the session cookie (`__Host-portal_session`), the encrypted payload, and the lookup middleware that attaches `user` to every request. - Plug the callback into session creation. Auth still ends with a Pino log + redirect; the SPA still sees the user anonymous on the next request. - Sentinel / TLS configuration. Future-var keys are documented in `.env.example` for when the prod deploy lands. --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #109 |

fix(portal-bff): drop strict amr check — flow blocked when Entra omits the claim (#108)
## Bug
After a real sign-in against the Entra tenant, the callback rejected the flow with:
```
{"context":"AuthCallback","event":"auth.flow_error","failure":{"kind":"amr-missing"}}
```
The user landed on the SPA with `?auth_error=amr-missing` instead of authenticated. Every dev sign-in is blocked.
## Root cause
PR #107's `amr-missing` guard misread ADR-0011's intent. `amr` is an **optional** claim in Entra ID tokens: it's populated for fresh interactive sign-ins where Conditional Access asked for an MFA method, and frequently absent for SSO / refresh flows or in tenants where no CA policy is configured on the app registration. Rejecting tokens on empty `amr` blocks every legitimate sign-in against such a tenant.
ADR-0011 actually specifies:
- **Conditional Access** (org-side) is the enforcement layer for "MFA happened".
- The **`@RequireMfa({ freshness: 600 })`** decorator (designed-in, no v1 consumer) is what guards sensitive routes.
- The BFF surfaces `amr` through the audit log and the future guard, not as a callback precondition.
## Fix
- **[`auth.errors.ts`](apps/portal-bff/src/auth/auth.errors.ts)**: drop the `amr-missing` variant from the `AuthCodeFlowError` discriminator. Three failure modes left: `state-mismatch`, `flow-expired`, `token-exchange-failed`. MSAL's ID-token validation (signature, issuer, audience, exp, nbf) is the real gate at this stage.
- **[`auth.service.ts`](apps/portal-bff/src/auth/auth.service.ts)**: `toAuthenticatedUser` keeps extracting `amr` and passing it through (as a possibly-empty string array) so the structured log line and the future `@RequireMfa` guard still see it. The strict `if (amr.length === 0) throw` is replaced by a comment explaining the new shape.
- **[`auth.service.spec.ts`](apps/portal-bff/src/auth/auth.service.spec.ts)**: the `'throws amr-missing'` test becomes `'returns the user even when the ID token has no amr claim'` — asserts the array passes through empty rather than blocking the flow.
## Verification
- `nx run-many -t lint test build --projects=portal-bff` — green. **52/52 specs**.
- Manual smoke: end-to-end sign-in against the live tenant now lands cleanly on the SPA; Pino's `auth.signed_in` log shows the resolved identity with `amr` (often `[]` until CA is configured on the org side).

feat(portal-bff): /auth/callback route — token exchange + amr check (#107)
## Summary
Fourth step of ADR-0009 wiring. Closes the OIDC round-trip on the BFF side (modulo session persistence — that's the next PR per ADR-0010). Entra now redirects the user back to `GET /api/auth/callback`; the BFF verifies the state, exchanges the code for tokens via MSAL's `acquireTokenByCode`, runs the ADR-0011 `amr` sanity-check, logs the resolved identity to Pino, clears the single-use pre-auth cookie, and 302s the user back to the SPA.
## What lands
- **[`auth.errors.ts`](apps/portal-bff/src/auth/auth.errors.ts)** — discriminated-union `AuthCodeFlowError` (`state-mismatch` / `flow-expired` / `amr-missing` / `token-exchange-failed`) + `AuthCodeFlowException` wrapper. The `kind` field doubles as the `?auth_error=<code>` query param on the SPA-bound redirect so the front-end can render an exact message without duplicating the string set.
- **[`AuthService.completeAuthCodeFlow(code, state, preAuth, now?)`](apps/portal-bff/src/auth/auth.service.ts)** — verifies state binding, refuses cookies older than the 5-minute flow TTL, calls MSAL Node's `acquireTokenByCode` with the stored verifier, validates `amr` is non-empty (the BFF sanity-check per ADR-0011 — Entra Conditional Access on the org side does the real enforcement), extracts `oid` / `tid` / `preferred_username` / `name` / `amr` into an `AuthenticatedUser` shape.
- **[`auth.cookie.ts`](apps/portal-bff/src/auth/auth.cookie.ts)** gains `clearPreAuthCookieOptions()` mirroring the set-options minus `maxAge` so the browser actually drops the cookie. (Cookies match by name + path + secure; getting any of those wrong leaves the old cookie in place.)
- **[`AuthController.callback()`](apps/portal-bff/src/auth/auth.controller.ts)** — `@Get('callback')`. Always clears the cookie first (single-use). Bails on Entra-side errors (`?error=`), missing query params, missing or malformed cookie — each branch logs a structured Pino warning and redirects with the right `auth_error` code. On `AuthCodeFlowException`, logs + redirects with the typed `kind`. On success, logs an `auth.signed_in` event with `oid`, `tid`, `username`, `amr` (PII-sensitive bits only; no tokens), then 302s to `entra.postLogoutRedirectUri`.
## Decisions worth flagging
- **`postLogoutRedirectUri` reused as the SPA root URL.** Semantically a tiny stretch (its OIDC role is the post-logout destination) but the value is the same. Avoids one more env var until / unless the two URLs need to diverge.
- **Cookie cleared FIRST**, before any branching. Single-use is a property we want guaranteed regardless of which path exits the handler — overlap with a parallel /login from the same browser session would otherwise leak a usable cookie.
- **`auth.signed_in` logged via Pino, not via the audit module.** ADR-0013 wants this in the audit table; pairing audit with the session that ships in the next PR keeps the audit row carrying a `session_id` (otherwise it'd reference a "phantom" auth event with no follow-up).
- **`amr` non-empty is the BFF's check; the Conditional Access policy is what enforces "MFA happened".** ADR-0011 explicitly factors it this way — empty `amr` would indicate a policy misconfiguration where MFA never fired.
## Verification
- `nx run-many -t lint test build --projects=portal-bff` — green.
- **52 / 52 specs** (was 39; +13 across the new completeFlow branches and callback branches).
- Service spec covers happy path + 6 failure modes (state mismatch, flow expired, amr missing, MSAL throws, MSAL returns null, oid claim missing).
- Controller spec covers happy redirect, Entra error, missing cookie, AuthCodeFlowException branch, missing query, malformed cookie.
## Manual smoke test (end-to-end)
1. `apps/portal-bff/.env` carries real `ENTRA_*` + `SESSION_SECRET`.
2. `nx serve portal-bff` and `nx serve portal-shell`.
3. Open `http://localhost:3000/api/auth/login` → redirects to Entra.
4. Authenticate. Entra redirects to `http://localhost:3000/api/auth/callback?code=…&state=…`.
5. BFF processes; redirects to `http://localhost:4200/`. Pino log shows `auth.signed_in` with the user's `oid`, `tid`, `username`, `amr`.
6. Tamper test: open the link again, hand-edit the `state=` in the callback URL → BFF redirects with `?auth_error=state-mismatch`.
## What this PR explicitly does NOT do
- **Persist a session.** The user is "authenticated" from the BFF's point of view (identity resolved + logged) but the next request lands anonymous. Closes in the Redis sessions PR per ADR-0010.
- **Audit log entry.** Pairs with sessions so the row carries a `session_id`.
- **Logout / `/me`.** Land after sessions.

feat(portal-bff): /auth/login route — pkce flow start + signed cookie (#105)
## Summary
Third step of ADR-0009 wiring. Adds the first OIDC route, `GET /api/auth/login`: it 302s the browser to Entra's authorize endpoint with a freshly-generated state + PKCE challenge, and stashes the matching `{state, codeVerifier}` payload in a short-lived signed cookie so the next-PR callback can verify the round-trip.
## What lands
- **Cookie infra**: `cookie-parser` + `@types/express` deps; `main.ts` mounts the cookie middleware with the `SESSION_SECRET` signing key. Signed cookies are now available via `req.signedCookies` for the upcoming callback.
- **[`.env.example`](apps/portal-bff/.env.example)** promotes `SESSION_SECRET` from a future-vars comment into an active section, with a one-liner showing how to generate 32 random bytes.
- **[`check-session-secret.ts`](apps/portal-bff/src/config/check-session-secret.ts)** — boot-time guard: refuses to start if `SESSION_SECRET` is unset, still the .env.example placeholder, or decodes below 32 bytes of entropy. Same family as `check-database-url` / `check-entra-config`.
- **[`auth.service.ts`](apps/portal-bff/src/auth/auth.service.ts)** — `beginAuthCodeFlow()` uses MSAL's `CryptoProvider` for canonical PKCE verifier / challenge generation and a fresh GUID state per call, calls `msal.getAuthCodeUrl()` with the configured redirect URI + OIDC scopes (`openid profile email` — no `offline_access` in v1), and returns `{ authUrl, preAuthPayload }`.
- **[`auth.cookie.ts`](apps/portal-bff/src/auth/auth.cookie.ts)** — `portal_pre_auth` name, 5-minute TTL, shared `CookieOptions`: `signed`, `httpOnly`, `sameSite: 'lax'` (lets Entra's cross-site top-level redirect back through), `secure` toggled by `NODE_ENV`.
- **[`auth.controller.ts`](apps/portal-bff/src/auth/auth.controller.ts)** — `@Controller('auth') @Get('login')`: writes the cookie then 302s. Thin shell around the service.
- **AuthModule** registers the new controller + service alongside the existing `ENTRA_CONFIG` and `MSAL_CLIENT` providers.
## Decisions worth flagging
- **Scope deliberately stops before the callback.** It's the next PR. Clicking `/auth/login` today round-trips through Entra and lands on a 404 — bounded mid-state, documented in the commit and here.
- **State + verifier in the cookie, not in Redis.** Keeps `/login` stateless (no server-side store), which means the BFF stays horizontally scalable from day one without sticky-session config. The next-PR callback reads `req.signedCookies` to recover the payload.
- **`portal_pre_auth`, not `__Host-portal_pre_auth`.** `__Host-` mandates `Secure`, and local dev is HTTP. The prefix + `Secure: true` lands together with the production TLS hardening ADR.
- **No `offline_access` scope.** Sessions are short-lived (per ADR-0010); the user re-authenticates through Entra rather than the BFF refreshing tokens behind their back. Smaller token footprint, less code to write, easier to reason about.
- **5-minute cookie TTL.** Enough for the Entra round-trip (including a fresh MFA prompt), short enough that a stale cookie can't be replayed long after the user abandoned the flow.
## Verification
- `nx run-many -t lint test build --projects=portal-bff` — green.
- **39 / 39 specs** (was 30; +9 across `check-session-secret`, `auth.service`, `auth.controller`).
- The service spec mocks `getAuthCodeUrl`, asserts the redirect URI / scopes / S256 method, the state-verifier identity between the cookie payload and what's sent to Entra, and fresh-per-call replay protection.
- The controller spec asserts the cookie name + options + serialized payload and the 302 redirect.
## Manual smoke test (next PR completes the loop)
1. `apps/portal-bff/.env` has real `ENTRA_*` + `SESSION_SECRET`.
2. `nx serve portal-bff`.
3. `curl -i http://localhost:3000/api/auth/login` → 302 with `Set-Cookie: portal_pre_auth=…; HttpOnly; SameSite=Lax; Path=/`, `Location: https://login.microsoftonline.com/<tenant>/oauth2/v2.0/authorize?...`.
4. Open the `Location` in a browser, authenticate, Entra redirects to `http://localhost:3000/api/auth/callback?code=…&state=…` → 404 today, will be the next PR.
## Next PR on the auth track
`GET /api/auth/callback` — reads the signed cookie, verifies `state` matches, calls `acquireTokenByCode` with the stored verifier, validates the ID token (issuer, audience, exp, nonce, `amr` per ADR-0011), clears the pre-auth cookie, logs the resolved user identity, redirects to `/` (SPA). Still no session — that's the PR after.

feat(portal-bff): msal confidential client provider in AuthModule (#104)
Second step of ADR-0009 wiring. AuthModule now exposes the `@azure/msal-node` confidential client alongside the parsed Entra config — the building block the upcoming OIDC routes inject to issue the auth-code URL, exchange the callback code for tokens, and acquire downstream tokens on behalf of the user. What lands: - `@azure/msal-node` added as a direct dependency (^5.2.1). - `apps/portal-bff/src/auth/msal-client.token.ts` — `MSAL_CLIENT` string token + `ConfidentialClientApplication` type re-export. Mirrors the `ENTRA_CONFIG` token shape from PR #102. - AuthModule grows a factory provider for `MSAL_CLIENT`: - Injects `ENTRA_CONFIG` + nestjs-pino `Logger`. - Builds a `ConfidentialClientApplication` with `clientId`, `authority`, `clientSecret` from the parsed config. - Wires `system.loggerOptions.loggerCallback` to forward MSAL's internal log lines into the Pino stream (per ADR-0012) — Error → logger.error, Warning → logger.warn, Verbose / Trace → logger.debug, Info → logger.log. PII logging is disabled by default so tokens / user identifiers never leak into our structured log records. - Sets MSAL's `logLevel` to Info — Pino's own threshold re-filters from there. - All MSAL log lines carry the `msal` Pino context for easy isolation in log queries. - `AuthModule.exports` extended to include `MSAL_CLIENT`. Verification: - `nx run-many -t lint test build --projects=portal-bff` — green. - 30/30 specs (was 29; +1 covering MSAL client construction). - New spec imports `nestjs-pino`'s `LoggerModule.forRoot({ pinoHttp: { level: 'silent' } })` to provide the same Logger the production app supplies via `ObservabilityModule`, without flooding test stdout. Two tests assert the provider tree resolves correctly (ENTRA_CONFIG + MSAL_CLIENT) and one re-checks the missing-env failure mode still propagates through the new factory. Construction is cheap — MSAL Node defers authority discovery to the first auth call — so the client is built eagerly at module init. The factory is injection-only; no MSAL methods get invoked yet. Routes land in the next PR. <!-- PR title format — becomes the squash-merge subject on main, validated by commitlint. <type>(<scope>): <short description> Examples: feat(portal-shell): add user-preferences panel skeleton fix(portal-bff): correct env var bracket access docs(decisions): add ADR-0018 for security baseline chore(deps): bump @nx/* to 22.7.2 Imperative mood, lowercase, no trailing period, target ≤ 70 chars.

feat(portal-bff): entra config foundation — boot validator + auth module (#102)
## Summary First step of ADR-0009 wiring on the BFF: capture the Entra app-registration env vars in the boot pipeline so subsequent PRs can plug `@azure/msal-node` onto a typed, already-validated config without re-reading `process.env`. **No MSAL client, no OIDC routes, no session integration yet** — those land in follow-up PRs. ## What lands - **[`.env.example`](apps/portal-bff/.env.example)** promotes the Entra block from its previous "future-vars" comment stub to an active section. Six keys: - `ENTRA_INSTANCE_URL` — the Microsoft login endpoint (e.g. `https://login.microsoftonline.com/`). - `ENTRA_TENANT_ID`, `ENTRA_CLIENT_ID`, `ENTRA_CLIENT_SECRET` — the values from the Entra app-registration UI. - `ENTRA_REDIRECT_URI`, `ENTRA_POST_LOGOUT_REDIRECT_URI` — consumed by the OIDC routes in a follow-up PR. Multi-tenant `ENTRA_ACCEPTED_TENANT_IDS` stays in the future-vars comment until External ID activation (ADR-0008 phase 2). - **[`apps/portal-bff/src/config/check-entra-config.ts`](apps/portal-bff/src/config/check-entra-config.ts)** — boot-time validator mirroring `check-database-url.ts`. Verifies every required key is present, the instance URL is `https://` and ends with `/`, tenant + client IDs are UUIDs, none of them are the literal placeholder values from `.env.example`, and the two redirect URIs parse as URLs. Returns a typed `EntraConfig` object with a pre-computed `authority` field (`${instanceUrl}${tenantId}`) so the future MSAL factory does not re-derive it. - **[`auth.module.ts`](apps/portal-bff/src/auth/auth.module.ts)** — `AuthModule` whose v1 surface is one provider: the parsed `EntraConfig` keyed by the `ENTRA_CONFIG` injection token. Factory delegates to `assertEntraConfig()`. Non-global on purpose — consumers state intent by importing the module. - **Bootstrap wiring** — `main.ts` calls `assertEntraConfig()` alongside `assertDatabaseUrl()` so misconfiguration fails fast at boot rather than mid-request (per ADR-0018 §"BFF env-var loading"). `AppModule` imports `AuthModule`. ## Naming choice Chose `ENTRA_*` rather than `AZURE_AD_*` to align with the ADR text (Microsoft Entra ID, post-2023 rebrand). The values you copy from the Entra app-registration UI go into `apps/portal-bff/.env` (git-ignored). ## Decisions worth flagging - **Validator called twice** — once in `main.ts` (boot-time fail-fast) and once in the `AuthModule` factory (to obtain the value for DI). Both reads are idempotent and trivially cheap. The duplication is intentional: boot-time gives a clear, pre-NestFactory error; the factory call surfaces the typed value to consumers. - **No `@azure/msal-node` dependency added yet** — introducing the dep without a consumer would be a smell. Lands in the next PR alongside the MSAL client factory. - **Pre-computed `authority`** in the parsed config rather than letting each MSAL consumer concatenate `instanceUrl + tenantId`. One place to change if the multi-tenant authority (`/organizations`, `/common`) replaces the tenant-scoped one when External ID activates. ## Verification - `nx run-many -t lint test build --projects=portal-bff` — green. - **29 / 29 specs** (was 20; +9 from the new entra-config spec + auth.module spec). - Boot smoke test (manual): with the placeholder values in `.env.example`, `nx serve portal-bff` aborts immediately with `ENTRA_CLIENT_ID is still the .env.example placeholder (…)`. With real values in a local `.env`, the BFF starts normally. ## Test plan - [x] Lint + test + build green. - [x] Validator unit-test covers happy path + every documented failure mode. - [ ] Manual: drop the real Entra values you obtained into `apps/portal-bff/.env`, `nx serve portal-bff` boots clean. - [ ] Manual: temporarily blank out one of the four `ENTRA_*` keys → BFF aborts at boot with a clear message naming the missing key. ## Next PRs on the auth track 1. Install `@azure/msal-node`, add the `MsalConfidentialClient` factory provider in `AuthModule`, expose it via DI. 2. First OIDC routes: `/api/auth/login` (PKCE-initiated redirect to Entra) + `/api/auth/callback` (token exchange + ID-token validation, audit-logged, no session persistence yet). 3. Session persistence per ADR-0010 (Redis + AES-GCM, `__Host-portal_session` cookie). Closes the auth loop. 4. RP-initiated logout, CSRF protection, route guards. --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #102 |

feat(portal-bff): audit log foundation per ADR-0013 (#76)
## Summary Lays down the append-only audit log per ADR-0013: schema declaration, first migration with role grants, NestJS `AuditWriter` service. Typed event-family methods, the separate `AUDIT_DATABASE_URL` pool, the retention job, and the live-DB integration tests are explicitly listed as "wired as features land" in the ADR's confirmation block — they ship when the matching feature ADRs do. ## What lands **Prisma schema** ([`apps/portal-bff/prisma/schema.prisma`](apps/portal-bff/prisma/schema.prisma)): - `multiSchema` preview enabled; datasource declares `public` + `audit` schemas. - `AuditEvent` model: `id` (uuid), `createdAt`, `eventType` (free-form in v1), `audience` enum (`workforce | customer`), `actorIdHash`, `traceId`, `subject`, `outcome` enum (`success | failure | denied`), `payload` (jsonb). - Indexes on `createdAt`, `eventType`, `traceId` — covering the three obvious query shapes. **Migration** ([`prisma/migrations/*_init_audit_schema/migration.sql`](apps/portal-bff/prisma/migrations/20260510011453_init_audit_schema/migration.sql)): - Standard Prisma `CREATE TABLE` / enums output, then the **append-only contract** re-applied explicitly: - `ALTER TABLE/TYPE OWNER TO audit_owner`. - `GRANT INSERT` to `audit_writer`, `SELECT` to `audit_reader`, **`SELECT, DELETE`** to `audit_archiver` (SELECT is needed to evaluate the `created_at` predicate of "delete older than retention" — Postgres requires SELECT on every column referenced in DELETE's WHERE). - `GRANT USAGE` on the enum types to all three roles (without it `audit_writer.INSERT` fails with "permission denied for type"). - **No** GRANT for `UPDATE` / `TRUNCATE` to anyone — including `audit_owner` at runtime; only fresh schema migrations amend the table. **Service** ([`apps/portal-bff/src/audit/`](apps/portal-bff/src/audit/)): - `AuditWriter.recordEvent(input)` — single entry point. Wraps every INSERT in a transaction whose first statement is `SET LOCAL ROLE audit_writer`, so the role contract holds at runtime even from the otherwise-privileged BFF connection. - `traceId` auto-resolved from the active OTel span (so audit row joins with traces and Pino logs on the same `trace_id`). - `actorIdHash` auto-resolved from CLS (key `actorIdHash`) with explicit input-side override; `null` when neither is set (placeholder until ADR-0009 / ADR-0010 guards populate CLS). - Errors propagate (no catch-and-swallow), per ADR-0013's "blocking writes: no audit ⇒ no action". **Tests** — 8 unit tests on `AuditWriter` (mocked Prisma + CLS): role-locking ordering, input pass-through, `Prisma.JsonNull` for missing payload, CLS-vs-input precedence on `actorIdHash`, OTel trace capture, error propagation. ## End-to-end verification (manual, against local-dev Postgres) ``` INSERT under audit_writer: ok UPDATE under audit_writer: permission denied for table events DELETE under audit_writer: permission denied for table events DELETE under audit_archiver: ok, row removed (after the SELECT-grant fix) ``` ## ADR-0013 §Confirmation rewritten Two-block split: "wired in foundation PR" lists what landed here; "wired as features land" lists the typed event-family methods, AUDIT_DATABASE_URL connection split, startup self-test probe, retention purge job, salt-shared cross-correlation test, and live-DB role-contract integration tests — each anchored to the feature ADR that triggers it. ## Recovery for anyone with a pre-existing local-dev DB If your local-dev Postgres already had the audit migration applied **before** the SELECT-grant fix, the archiver's DELETE will fail. Two options: 1. Apply the missing grant directly: ```bash psql "$DATABASE_URL" -c "GRANT SELECT ON audit.events TO audit_archiver;" ``` 2. Or wipe the volume and re-migrate cleanly: ```bash ./infra/local/dev.sh down -v ./infra/local/dev.sh up pnpm --filter @apf-portal/source exec prisma migrate deploy # or `cd apps/portal-bff && pnpm exec prisma migrate deploy` ``` Fresh DBs land with the corrected migration directly. ## Out of scope (separate PRs) - Typed event-family methods (`signIn`, `signInFailed`, …) — added per matching feature ADR. - `AUDIT_DATABASE_URL` separate connection pool — defense-in-depth, when production needs it. - Startup self-test probe (deliberate failing UPDATE asserting rejection) — lands with the connection split. - Retention purge job (`audit_archiver` daily cron) — phase-3b infra. - Live-DB integration tests asserting the role contract — Testcontainers-style harness, separate PR. ## Test plan - [ ] CI green on this PR. - [ ] `prisma migrate deploy` succeeds on a fresh DB (the recovery instructions cover the SELECT-grant gap for already-migrated dev DBs). - [ ] `psql -c "\dp audit.events"` shows the expected privilege matrix: `audit_owner=arwdDxtm/audit_owner`, `audit_writer=a/audit_owner`, `audit_reader=r/audit_owner`, `audit_archiver=rd/audit_owner`. - [ ] BFF boots; calling `AuditWriter.recordEvent` from a controller (manual smoke once a real flow lands) writes to `audit.events` with the expected `trace_id` matching the request's Jaeger span. --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #76 |

feat(portal-shell): wire spa-side opentelemetry tracing (#72)
## Summary Phase 2 of ADR-0012 — closes the loop SPA → BFF → DB. After this PR, a single user action (initial page load, click, form submit) produces one trace whose root span is owned by the SPA and whose child spans cover the BFF request, Postgres queries through Prisma, and (eventually) Redis / downstream-API hops. ## What lands **Browser-side OTel libs** (production deps): - `@opentelemetry/sdk-trace-web` — browser tracer + provider - `@opentelemetry/exporter-trace-otlp-http` — OTLP/HTTP+JSON exporter - `@opentelemetry/instrumentation` — auto-instrumentation runtime - `@opentelemetry/instrumentation-fetch` — `fetch` + W3C `traceparent` propagation - `@opentelemetry/instrumentation-document-load` — initial-paint timings - `@opentelemetry/instrumentation-user-interaction` — click / keypress / submit No `@opentelemetry/context-zone`: the workspace is zoneless per ADR-0004; the default `StackContextManager` covers the auto-instrumented paths. Custom spans across `await` will need explicit `context.with(...)` plumbing — fine, encountered as code lands. **Code**: - [`apps/portal-shell/src/observability/tracing.ts`](apps/portal-shell/src/observability/tracing.ts) — `WebTracerProvider` bootstrap. Documents the load-order constraint inline (same pattern as the BFF: must be the very first import of `main.ts`, otherwise auto-instrumentations miss everything imported above). - `apps/portal-shell/src/main.ts` now imports the tracing module as line 1. **CORS plumbing** for end-to-end trace propagation: - BFF (`apps/portal-bff/src/main.ts`) calls `enableCors` with a minimal dev allowlist (`http://localhost:4200`) and explicit permission for the W3C `traceparent` / `tracestate` headers. The full security-grade CORS (per-environment allowlists, helmet, cookie-session, CSRF) belongs to the future phase-2 security ADR — this PR adds the strict minimum for the SPA→BFF trace context to survive cross-origin pre-flight. - OTel Collector (`infra/local/otel-collector.yaml`) gains a `cors` block on its OTLP/HTTP receiver so the browser's own OTLP POST clears its pre-flight. **ADR-0012 §Confirmation** rewritten: a new "Wired in the SPA foundation PR (phase 2)" block enumerates what landed here; the carry-over "Wired as features land" list drops the SPA-side SDK item and adds a follow-up note about the security-grade CORS. ## Verification ```bash pnpm exec nx run-many -t lint test build # 8 projects green pnpm audit # 0 vulns ./infra/local/dev.sh up observability # bring up Collector + Jaeger ./infra/local/dev.sh # (separately, BFF stack — your choice) pnpm nx serve portal-bff # localhost:3000 pnpm nx serve portal-shell # localhost:4200 ``` Open http://localhost:4200 → a `document_load` trace appears in http://localhost:16686 with `service.name=portal-shell`. From DevTools, run `fetch('http://localhost:3000/api/health').then(r => r.json())` → a fetch span appears with a child BFF span on the same trace. ## Test plan - [ ] CI green on this PR. - [ ] After local up, `document_load` span visible in Jaeger UI for the SPA. - [ ] Cross-origin fetch from SPA carries `traceparent` (visible in Network tab) and produces a single end-to-end trace SPA → BFF in Jaeger. - [ ] DevTools console shows no CORS warnings about `traceparent`, `tracestate`, or the `localhost:4318/v1/traces` POST. --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #72 |

style(portal-bff): apply prettier to check-database-url.ts (#71)
## Summary Cosmetic-only follow-up to #70. Collapses one over-cautious multi-line `throw new Error(...)` into a single line that fits within the project's 100-char `printWidth`. The reformat was produced by lint-staged **during** the amend that landed #70, but applied to the working tree only — the modification never made it back into the staged content of the amend. The merged commit therefore carries the un-prettified version. Spotted locally with `pnpm exec prettier --check apps/portal-bff/src/config/check-database-url.ts` failing. Left unchecked, the next PR's `check` job would break at `format:check` for unrelated reasons. ## Test plan - [ ] CI green on this PR (`format:check` clean). - [ ] No behavioural change — only whitespace. --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #71 |

feat(portal-bff): observability foundations (Pino + CLS + OTel) (#70)
## Summary
Implements ADR-0012 phase 1, BFF side. The SPA wiring is a separate phase-2 PR.
The BFF now emits structured JSON logs to stdout, tagged with `trace_id` / `span_id` from the active OTel context, and exports OTLP traces over HTTP/Protobuf to the Collector that already runs in the local-dev compose. Anything Nest, Express, HTTP-out, Prisma (Postgres) or `ioredis` does is auto-spanned. A `GET /api/health` liveness endpoint is added to round things out.
## What lands
**Runtime libs added** (production deps):
- `nestjs-pino`, `pino`, `pino-http` — structured logging
- `nestjs-cls` — request-scoped context
- `@opentelemetry/api` / `sdk-node` / `resources` / `semantic-conventions`
- `@opentelemetry/exporter-trace-otlp-proto` (HTTP/Protobuf, port 4318)
- `@opentelemetry/instrumentation-{http,express,nestjs-core,pg,ioredis,pino}` — curated, **no** `auto-instrumentations-node` mass-import (anti-bricolage)
Dev: `pino-pretty` (gated by `NODE_ENV`).
**Code:**
- `apps/portal-bff/src/observability/tracing.ts` — OTel `NodeSDK` bootstrap. Documents the load-order constraint inline (must be the very first import of `main.ts`). Pure side-effect module.
- `apps/portal-bff/src/observability/observability.module.ts` — composes `ClsModule` (UUID per request stored as `request_id`) and `LoggerModule` (`pino-pretty` in dev, raw JSON in prod, `LOG_LEVEL` env-driven, `/health` excluded from auto-logging, `X-Request-Id` honoured if inbound).
- `apps/portal-bff/src/health/{health.controller,health.module,health.controller.spec}.ts` — `GET /api/health` returning `{status, uptimeSeconds, service, version}`. Cheap liveness only — `/readiness` lands when dependencies have a readiness story.
- `apps/portal-bff/src/config/check-database-url.{ts,spec.ts}` — fail-fast validator called from `main.ts` before NestFactory boots. Catches the same family of bug that bit pgweb in #63: a literal special character in `POSTGRES_PASSWORD` that needs URL-encoding in `DATABASE_URL`. Prisma requires a URL string (no discrete-flag escape hatch), so early validation + a clear error message is the v1 mitigation. Six unit tests cover happy path, missing URL, wrong scheme, encoded special chars, literal `@` in password, malformed URL.
**Wiring:**
- `main.ts` imports `./observability/tracing` as line 1, then uses `app.get(Logger)` from `nestjs-pino` with `bufferLogs: true` so early-bootstrap lines are not lost.
- `app.module.ts` imports `ObservabilityModule` first, then `PrismaModule`, then `HealthModule`.
- `apps/portal-bff/.env.example` promotes `LOG_LEVEL`, `OTEL_SERVICE_NAME`, `OTEL_SERVICE_VERSION`, `OTEL_EXPORTER_OTLP_ENDPOINT`, `OTEL_EXPORTER_OTLP_PROTOCOL`, `OTEL_TRACES_SAMPLER` from the "future" comment to active settings — defaults target the local-dev Collector.
- Both `apps/portal-bff/.env.example` and `infra/local/.env.example` now spell out the URL-encoding constraint on `POSTGRES_PASSWORD` with the char-by-char encoding table (`@` → `%40`, etc.).
**ADR-0012 §Confirmation** rewritten to distinguish what landed in this PR from what is wired as the corresponding feature ADRs ship (CLS keys for `session_id` / `user_id_hash` / `audience`, `LOG_USER_ID_SALT` enforcement, redact list, custom spans, SPA-side SDK, full integration tests, prod Collector config).
## Trace ↔ log correlation
Automatic via `@opentelemetry/instrumentation-pino` — every Pino record gets `trace_id` and `span_id` injected from the active OTel context. No CLS gymnastics needed for that concern.
## Verification
```bash
pnpm exec nx run-many -t lint test build # 8 projects green
pnpm audit --audit-level=moderate # 0 vulnerabilities
./infra/local/dev.sh up observability # start Collector + Jaeger
cp apps/portal-bff/.env.example apps/portal-bff/.env
pnpm nx serve portal-bff
curl http://localhost:3000/api/health
# → {"status":"ok","uptimeSeconds":N,"service":"portal-bff","version":"dev"}
```
Then hit `GET http://localhost:3000/api` once or twice and open http://localhost:16686 — the corresponding spans appear in Jaeger, and Pino logs on stdout carry the matching `trace_id`.
## Test plan
- [ ] `nx run-many -t lint test build` green on this PR's CI run.
- [ ] `pnpm audit` clean.
- [ ] BFF boots, `/api/health` returns the expected JSON.
- [ ] Pino logs in dev are colourised one-liners; in prod they would be raw JSON (toggled by `NODE_ENV=production`).
- [ ] With the local-dev stack's `--profile observability` active, traces are visible in Jaeger UI.
- [ ] Each Pino log line for a request carries the same `trace_id` as the trace span in Jaeger.

fix(portal-bff): downgrade Prisma to 6.x for nestjs-prisma compatibility (#3)
## Summary
- Pin `prisma` and `@prisma/client` to `^6` (resolved 6.19.3) instead of the previous `^7`.
- Switch the generator in `apps/portal-bff/prisma/schema.prisma` from `prisma-client` to `prisma-client-js` (Prisma 6's default).
- Add the explicit `url = env("DATABASE_URL")` in the `datasource db` block (required by Prisma 6; was implicit in Prisma 7 via `prisma.config.ts`).
- Remove `apps/portal-bff/prisma.config.ts` (Prisma 7-only feature).
- Drop the now-irrelevant `/generated/prisma` entry from `apps/portal-bff/.gitignore`.
## Motivation
Two distinct Prisma 7 breaking changes surfaced as runtime errors in `pnpm nx serve portal-bff`:
1. **Generator output path:** Prisma 7's default `prisma-client` generator writes to a custom output dir declared in the schema. `@prisma/client/default.js`'s runtime stub still resolves `.prisma/client/default` in a sibling `node_modules/.prisma/client/`, which only the legacy `prisma-client-js` generator populates. Result: `ESM loader error: Cannot find module '.prisma/client/default'`.
2. **PrismaClientOptions API:** In Prisma 7, `PrismaClientOptions` no longer exposes `datasourceUrl` nor `datasources`. The connection must come through a driver adapter (e.g. `@prisma/adapter-pg`). `nestjs-prisma@0.27.0` calls `super(undefined)` when no `prismaServiceOptions` is passed, which Prisma 7 rejects with `PrismaClientInitializationError: PrismaClient needs to be constructed with a non-empty, valid PrismaClientOptions`.
Both issues are downstream of Prisma 7's "adapter-first" architecture being incompatible with `nestjs-prisma`'s still-Prisma-6-shaped wrapper. Working around each issue separately would lead into bespoke wiring (custom PrismaService, manual `@prisma/adapter-pg` install, hand-rolled DI). That's bricolage on a foundational layer.
Per CLAUDE.md ("default to stable, recognized, battle-tested choices; cutting-edge alternatives only when the trade-off is captured in an ADR"), the cheapest, cleanest fix is to use Prisma 6 — still actively maintained, fully aligned with `nestjs-prisma`'s design, supported by every tutorial and example in the wider ecosystem.
## Implementation notes
- ADR-0006 ("Persistence — PostgreSQL with Prisma") specifies "Prisma" without pinning a version. The version choice is a tactical detail. No ADR amendment.
- `apps/portal-bff/.env.example` is unchanged — the `DATABASE_URL` variable name is the same in Prisma 6 and 7.
- `prisma.config.ts` removed: it was a Prisma 7 file that Prisma 6 ignores; keeping it would only confuse a future contributor.
- The Prisma 7 `prisma-client` generator left a residual output dir at `apps/portal-bff/generated/` from the previous setup; removed locally and excluded from gitignore (no longer needed).
- Re-evaluate when `nestjs-prisma` releases an update aligned with Prisma 7's adapter model. The path back is symmetric: pin Prisma to `^7`, restore the schema's `prisma-client` generator, install `@prisma/adapter-pg`, and update `app.module.ts` to instantiate the adapter.
## Verification
- [x] `pnpm exec prisma generate` populates `node_modules/.../@prisma+client@6.19.3/.prisma/client/default.js` (no more 7.x in the active resolution).
- [x] `pnpm nx build portal-bff` green.
- [X] `pnpm nx serve portal-bff` boots cleanly (no `PrismaClientInitializationError`) — to be confirmed locally before merge. Connection to a real Postgres is out of scope of this PR; if Postgres is not running, an `ECONNREFUSED` is expected and unrelated.
- [ ] `pnpm ci:check` — runs in CI on PR open.
## Related
- [ADR-0006 — Persistence: PostgreSQL with Prisma](docs/decisions/0006-persistence-postgresql-prisma.md). Generator and version are tactical; no amendment.
- Future: revisit Prisma version when `nestjs-prisma` ships an update with first-class driver-adapter support.

chore: wire PostgreSQL + Prisma per ADR-0006
Add Prisma 7 + nestjs-prisma. The schema lives at
apps/portal-bff/prisma/schema.prisma with provider postgresql; the new
prisma-client generator (Prisma 7 default) outputs the typed client to
apps/portal-bff/generated/prisma/ which is gitignored.
apps/portal-bff/src/app/app.module.ts imports PrismaModule.forRoot
({ isGlobal: true }) so PrismaService is injectable across the BFF
without per-module imports.
apps/portal-bff/.env.example documents DATABASE_URL with a local-dev
default, plus a forward list of env vars introduced by upcoming phases
and ADRs (auth, sessions, MFA, observability, audit, downstream APIs)
- catalog reference, not implementation. The actual .env stays
gitignored at both repo root and app levels.
prisma.config.ts (Prisma 7's TypeScript config) is committed; it loads
DATABASE_URL via dotenv. Schema and migrations paths are pinned to
prisma/ relative to the bff app.
PostgreSQL provisioning, RLS policies for the dual-audience design,
the dedicated audit schema with role grants (audit_owner / audit_writer
/ audit_reader / audit_archiver per ADR-0013), and column-level
encryption for L3-scoped data are out of scope of this commit -
they belong with the future on-prem infrastructure ADR.

fix(portal-bff): use bracket notation for process.env access
The strict-TS option noPropertyAccessFromIndexSignature: true (set in
tsconfig.base.json per ADR-0004) forbids dot-notation access on index
signatures. process.env is typed as { [key: string]: string | undefined }
so process.env.PORT must be written process.env['PORT']. The Nx
generator wrote the dot form by default; fix to comply with the
project's strict-TS bar.
Touched: portal-bff main.ts and the three portal-bff-e2e support files
(global-setup, global-teardown, test-setup).
