## Summary

**Mechanical refactor only**, prerequisite to ADR-0026 PR 1. Renames the existing Prisma `User` model (the ADR-0020 user-directory cache, `oid` PK, written by `UserDirectoryService.recordSignIn`) to `UserDirectoryEntry`. Frees the `User` name for the upcoming ADR-0026 model (UUID PK, FK to `Person`, `lastSignInAt` — different semantics).

Zero behavioural change. Same columns, same indexes, same constraints, same call sites — just a different identifier on the model and the table.

## What lands

| File | Change |
| --- | --- |
| `apps/portal-bff/prisma/schema.prisma` | `model User` → `model UserDirectoryEntry`. `@@map("users")` → `@@map("user_directory_entries")`. Comment block extended to flag the upcoming distinction from ADR-0026's new `User`. |
| `apps/portal-bff/prisma/migrations/20260526200000_rename_users_to_user_directory_entries/migration.sql` | **New**. `ALTER TABLE "users" RENAME TO "user_directory_entries"` + `ALTER INDEX` renames for the PK constraint and the two named indexes (Postgres doesn't auto-rename these on table rename). |
| `apps/portal-bff/src/users/user-directory.service.ts` | Two renames: the **TS input interface** `UserDirectoryEntry` → `RecordSignInInput` (the existing name was a misnomer — it's the input to `recordSignIn`, not the entry itself, and would collide with the Prisma-generated `UserDirectoryEntry` type after the model rename). The **Prisma client ref** `this.prisma.user.upsert` → `this.prisma.userDirectoryEntry.upsert`. |
| `apps/portal-bff/src/users/user-directory.service.spec.ts` | Imports / mock setup / fixture type updated to track the two renames. |
| `apps/portal-bff/src/admin/admin-users-reader.service.ts` | `this.prisma.user.{count,findMany}` → `this.prisma.userDirectoryEntry.{count,findMany}`. `Prisma.UserWhereInput` → `Prisma.UserDirectoryEntryWhereInput`. Doc comments mentioning `public.users` updated to `public.user_directory_entries`. The class name `AdminUsersReader`, the endpoint URL `/api/admin/users`, the DTO `AdminUserDto`, and the local `interface UserRow` are unchanged — these are SPA/HTTP-facing identifiers, where the URL semantics ("admin user list") still hold regardless of the backing table name. |
| `apps/portal-bff/src/admin/admin-users-reader.service.spec.ts` | Mock setup updated to track the Prisma client field rename. |

## Why two renames in one file

`apps/portal-bff/src/users/user-directory.service.ts` had a TypeScript `interface UserDirectoryEntry` carrying the **input shape** of `recordSignIn(entry: UserDirectoryEntry)`. After the Prisma model rename to `UserDirectoryEntry`, that name would clash with the Prisma-generated row type. The fix is to rename the TS interface to its proper role — `RecordSignInInput` — at the same time. Net effect: clearer naming on both sides (the call-input name now describes the call, the persisted-row type name now describes the row).

## Recovery procedure (for anyone with the old migration applied locally)

The new migration `20260526200000_rename_users_to_user_directory_entries` is a pure `ALTER TABLE ... RENAME` + index renames — Prisma's `migrate dev` runs it forward without prompting:

```bash
cd apps/portal-bff && pnpm exec prisma migrate dev
# Should report: "Applied migration `20260526200000_rename_users_to_user_directory_entries`"
```

No `down -v` needed — existing data carries over.

## Test plan

- [x] `node scripts/check-catalogue-drift.mjs` — clean (4 / 24 / 7).
- [x] `node --test scripts/check-catalogue-drift.spec.mjs` — 22 tests passing.
- [x] `pnpm exec prettier --check` clean on the touched files.
- [x] Sweep grep — zero leftover `model User`, `prisma.user.`, `Prisma.UserWhereInput`, `interface UserDirectoryEntry`, or `public.users` references anywhere under `apps/portal-bff/src/` or `apps/portal-bff/prisma/`.
- [ ] **Locally**: `pnpm exec prisma migrate dev` applies the rename migration cleanly; `pnpm exec nx test portal-bff` runs the updated specs green.
- [ ] **Review focus** — the two-rename rationale in `user-directory.service.ts`, the migration's `ALTER INDEX` clauses (don't forget those — `ALTER TABLE ... RENAME` does NOT cascade to index names in Postgres), the unchanged class/URL/DTO/local-interface identifiers in `admin-users-reader.service.ts`.

## Why ship as a separate PR

ADR-0026 PR 1's nominal scope is `Person` + `User` + `UserScope` + provisioner + drift gate + PrincipalBuilder — already ~15+ files touched. Folding the rename into that PR would mix mechanical refactor with new design. Splitting keeps both PRs reviewable for what they actually do.

## What's next (post-merge)

**ADR-0026 PR 1** — `Person` + new `User` + `UserScope` schema + `PersonAndUserProvisioner` wired into `SessionEstablisher` + `Person.source` catalogue + drift-gate extension + `PrincipalBuilder` populating `Principal.user.{id, personId}` from real rows. Now unblocked.

julien ff1713eb6d fix(structures): align Structure.delegation_code FK action with Prisma default (#229)
CI / check (push) Failing after 4m9s
CI / commits (push) Has been skipped
CI / scan (push) Successful in 2m44s
CI / a11y (push) Successful in 2m58s
CI / perf (push) Successful in 5m34s
## Summary

Single-line fix on the `add_org_hierarchy` migration shipped in [#228](#228) (ADR-0027 PR 1). The FK action on `Structure.delegation_code` was `ON DELETE RESTRICT` (Prisma's default for **required** relations); the field is **optional** (`Structure.delegation Delegation?`), so Prisma's default is `ON DELETE SET NULL`. Mismatch caused `prisma migrate dev` to detect drift and prompt for a corrective migration on every run.

Caught locally on first VM-side validation (the workspace dev DB). No production deployment of #228 yet, so the fix is **edit-in-place** rather than a corrective sibling migration — keeps the repo's migration history clean.

## What lands

| File | Change |
| --- | --- |
| `apps/portal-bff/prisma/migrations/20260526143000_add_org_hierarchy/migration.sql` | `ON DELETE RESTRICT` → `ON DELETE SET NULL` on the `structures_delegation_code_fkey` FK. Inline comment explains the rule (nullable Prisma relation → SET NULL is the matching default; not matching it generates drift on every `migrate dev`). |

That's it. One line of SQL, one comment block. No schema.prisma change, no test change, no other file touched.

## Why edit-in-place vs new corrective migration

Edit-in-place is safe here because:

- The broken migration only exists in **dev local DBs** (Julien's WSL postgres). No staging, no preview env, no prod has applied it.
- Every dev who pulls this PR's fix wipes their local DB (`./infra/local/dev.sh down -v`) and reapplies — clean migration history, no "modified after applied" warning.
- The repo's migration list stays minimal — adding a corrective migration would carry the wart forever in `prisma/migrations/`.

Once a non-dev environment has applied a migration, the rule reverses: corrective migration mandatory, never edit in place. ADR-0015's "trunk-based + squash-merge" and the absence of a deployed environment at this stage gives us this one-time window.

## Recovery procedure for anyone who applied #228

```bash
# From the workspace root
./infra/local/dev.sh down -v   # wipe the local postgres volume
./infra/local/dev.sh up

# Pull this fix
git pull   # or git switch fix/adr-0027-pr1-fk-action-on-delete depending on local state

# Reapply migrations — no prompt this time
cd apps/portal-bff && pnpm exec prisma migrate dev
# Should report: "Applied migration `20260526143000_add_org_hierarchy`" and exit cleanly.
```

If anyone has a stray `drift_inspection/` folder under `prisma/migrations/` (artifact of the `--create-only` debugging step), delete it before reapplying — it's not in the repo, it was just diagnostic output.

## Test plan

- [x] `node scripts/check-catalogue-drift.mjs` — clean (unchanged by this fix).
- [x] `node --test scripts/check-catalogue-drift.spec.mjs` — 22 tests passing (unchanged).
- [x] `pnpm exec prettier --check` clean (SQL file unaffected by prettier but verified).
- [ ] **Locally on WSL** — wipe DB → pull fix → `prisma migrate dev` exits clean, no drift prompt.
- [ ] **Review focus** — the comment block in the migration explaining the rule (future-proof against the same mistake when ADR-0026 PR 1 adds optional relations).

## Notes for the reviewer

- **Why a comment block on the FK line, not on every nullable FK in future migrations?** This was caught the first time we hit it; a short note at the offending site is cheaper than amending `CLAUDE.md` with a "remember to match Prisma default actions" rule. If we hit the same mistake on ADR-0026 PR 1's `Person`/`User`/`UserScope` migration, we'll consider promoting it. For now: one inline comment at the place where the rule is non-obvious.
- **The drift gate doesn't catch this kind of mistake.** Catalogue drift gate scans string literals against TypeScript catalogues — it doesn't look at SQL referential actions. Postgres CHECK constraints (introduced for `Structure.kind` in this same migration) are not the same surface as FK referential actions. Catching this required actually running `prisma migrate dev`. A possible future improvement: a CI gate that runs `prisma migrate diff --from-migrations --to-schema-datamodel --script --shadow-database-url …` and fails if the diff is non-empty (zero-drift gate). Worth an ADR amendment if it becomes a recurring class of bug.

CI / scan (push) Successful in 3m27s
CI / a11y (push) Successful in 1m53s
CI / perf (push) Successful in 5m31s
## Summary

First implementation PR for [ADR-0027](docs/decisions/0027-portal-side-organisational-hierarchy.md) (`Region` / `Delegation` / `Structure` portal-side organisational hierarchy). **Schema + seed + drift-gate extension only** — no consumer code yet (the `PrismaScopeResolver` that dereferences `Structure.code` from `UserScope.value` lives in ADR-0026 PR 2, which depends on this PR landing first).

Independent of ADR-0026 PR 1 at the schema level — both can ship in parallel; ADR-0026 PR 2 depends on both.

## What lands

| File | Change |
| --- | --- |
| `apps/portal-bff/prisma/schema.prisma` | **+3 models**. `Region` (INSEE code PK + name + delegations[]). `Delegation` (dept code PK + name + regionCode FK + structures[]). `Structure` (portal code PK + name + kind discriminator + nullable unique finess/siret/codePaie + nullable delegationCode FK). All in the `public` schema; matches the ADR-0027 schema sketch verbatim. |
| `apps/portal-bff/prisma/migrations/20260526143000_add_org_hierarchy/migration.sql` | **New** hand-written migration. DDL for the 3 tables. `CHECK ("kind" IN (...))` constraint mirroring `STRUCTURE_KINDS`. Indexes (FK columns + kind + uniques). Inline INSERT seed: Région Nouvelle-Aquitaine (75), Délégation Gironde (33), structures `0330800013` + `0330800021` (médico-social, FINESS = code) + `siege` (APF national, no delegation/finess). |
| `apps/portal-bff/src/structures/structure-kind.ts` | **New**. Closed-set catalogue: `STRUCTURE_KINDS = [medico_social, antenne, dispositif, entreprise_adaptee, mouvement, administratif, siege] as const`. `type StructureKind` derived from the union, `isStructureKind` type guard. |
| `apps/portal-bff/src/structures/structure-kind.spec.ts` | **New**. Jest spec — catalogue content, no duplicates, type guard true for catalogue values + false for typos / cascade-only values / empty, type narrowing at call site. |
| `scripts/check-catalogue-drift.mjs` | **Extend**. New `extractStructureKinds(path)` + `findStructureKindViolationsInFile(path, validKinds, sourceText?)`. Property-literal scanner: detects `kind: 'X'` in object literals, restricted to files that import from `structure-kind.ts` (cheap text pre-filter — `kind` is a common property name on unrelated objects and we'd false-positive everywhere otherwise). Integrated into `scanWorkspace`. Error-message formatter switched on callee shape (`@Foo('x')` for decorators, `kind: 'x'` for property literals). Closing hint updated to reference both ADR-0025 and ADR-0027 catalogue locations. |
| `scripts/check-catalogue-drift.spec.mjs` | **Extend**. Fixture writes a synthesised `structure-kind.ts` alongside `authorization.types.ts`. New tests: extract STRUCTURE_KINDS, throw on missing constant, skip files without the import, no-violation on catalogue values, flag off-catalogue values, skip non-literal initialisers, line/column tracking, scanWorkspace aggregation (decorator + Structure.kind together), scanWorkspace exposes the structureKinds set. **22 tests total, all passing.** |

## Defense in depth

Three layers stack for `Structure.kind`, deliberately:

1. **TypeScript type union** `StructureKind` — compile-time check at every typed assignment.
2. **Postgres `CHECK` constraint** in the migration — runtime enforcement at INSERT / UPDATE, defends raw SQL / casts / untrusted API input.
3. **`scripts/check-catalogue-drift.mjs`** — CI gate asserting every `kind: 'X'` literal in structure-context files is in the catalogue.

The `Privilege` / `FunctionalRole` catalogues from ADR-0025 only have layer 1 + layer 3 (no DB enforcement — those values aren't persisted as schema-checked columns). ADR-0027's `Structure.kind` is persisted, so layer 2 was practical to add — bulletproof against any code path that bypasses the type system.

## Seed scope (and what's deliberately NOT in it)

Just what the 19 test-tenant personas reference per `notes/test-tenant-role-assignments.md`:

- `Region` 75 Nouvelle-Aquitaine (only region the personas exercise)
- `Delegation` 33 Gironde (only delegation)
- `Structure` 0330800013 (APF Bordeaux, medico-social, FINESS = code)
- `Structure` 0330800021 (Complexe Mérignac, medico-social)
- `Structure` `siege` (APF national, kind=siege, no FK to a delegation, no FINESS)

**No** placeholder `entreprise_adaptee`, `antenne`, or `dispositif` row — those kinds are valid per the catalogue but the test tenant doesn't exercise them, and adding gold-plate seed data would be misleading ("what is this row used for?"). The full APF inventory lands with [ADR-0029](#)'s cascade sync; this seed is **superseded** (not extended) by that sync.

## Notes for the reviewer

- **Naming conflict with the existing `User` model.** The current `schema.prisma` already has a `User` model — but it's the ADR-0020 user-directory cache (Entra `oid` as PK, written by `UserDirectoryService.recordSignIn`). ADR-0026 PR 1 introduces a different `User` (UUID PK, FK to `Person`, `lastSignInAt`). **Out of scope here** — ADR-0027 PR 1 doesn't touch `User`. Flagging now so ADR-0026 PR 1 can plan the migration path (likely: rename the existing `User` to `UserDirectoryEntry` or fold it into the new Person + User pair).
- **Migration is hand-written**, matching the style of the two existing migrations (`init_audit_schema`, `users_directory`). Timestamp `20260526143000` chosen so it sorts after the existing `20260514192014_users_directory`.
- **`@@schema("public")`** required on every new model because the audit log uses `multiSchema` (per ADR-0013) — the public/audit split is configured at the datasource.
- **Drift gate error-message formatter** now switches on callee shape — decorator violations still print as `@Foo('x')`, property-literal violations print as `kind: 'x'` to match the offending code shape.
- **No `pnpm ci:check` impact expected** at the bff level beyond the new spec; `pnpm ci:catalogue-drift` continues to report clean (`catalogues: 4 privileges, 24 roles, 7 structure kinds`).

## Test plan

- [x] `node scripts/check-catalogue-drift.mjs` — clean (4 / 24 / 7).
- [x] `node --test scripts/check-catalogue-drift.spec.mjs` — 22 tests passing.
- [x] `pnpm exec prettier --check` clean on the touched files.
- [ ] **On the dev VM**: `pnpm prisma migrate dev` applies the migration cleanly against a fresh `infra/local/dev.compose.yml` postgres. `pnpm prisma studio` shows the seeded Region / Delegation / Structure rows.
- [ ] **On the dev VM**: `pnpm exec nx test portal-bff` runs the new `structure-kind.spec.ts` green.
- [ ] **Review focus** — the `Structure` model shape (kind discriminator, nullable unique columns, FK to Delegation), the inline seed values vs `notes/test-tenant-role-assignments.md`, the drift-gate property-literal scanner's restriction to files importing from `structure-kind.ts`.

## What's next

Per [ADR-0027 §"Phasing"](docs/decisions/0027-portal-side-organisational-hierarchy.md):

1. **This PR** — Region / Delegation / Structure schema + seed + drift gate. 
2. **ADR-0026 PR 1** — `Person` / `User` / `UserScope` schema + `PersonAndUserProvisioner` + drift gate extension for `Person.source` + updated `PrincipalBuilder`. Independent of (1), can ship in parallel. **Needs to resolve the existing-`User`-name collision.**
3. **ADR-0026 PR 2** — `PrismaScopeResolver` replacing `StubScopeResolver` + `/admin/users/:id/scopes` admin screen + `prisma/seed.ts` populating the 19 personas' `user_scopes` rows pointing at this PR's `Structure.code` values. **Depends on both (1) and (2).**
4. **ADR-0029** (future) — Pléiades + Acteurs+ + cascade syncs + facet schemas + `Pole` / `Service` / per-source enrichment extensions to this PR's hierarchy.

## Summary

First PR of the **portal-admin User-list chantier** per [ADR-0020](docs/decisions/0020-portal-admin-app.md) §"v1 scope — User list (read-only)". Ships the **write side** only:

1. A new `public.users` table that holds the BFF's local cache of identities seen sign in to either portal-shell or portal-admin.
2. A `UserDirectoryService.recordSignIn(user)` upsert called from `SessionEstablisher.establish` after the blocking audit write.

The read side (`GET /api/admin/users` + the admin viewer SPA screen) lands in two follow-up PRs of the same chantier.

## Schema

[`prisma/schema.prisma`](apps/portal-bff/prisma/schema.prisma) gains a `User` model in the `public` schema:

| Column | Type | Notes |
| --- | --- | --- |
| `oid` | TEXT, PK | Entra's stable per-user identifier inside the tenant. Per-tenant uniqueness is sufficient for v1's single-workforce-tenant design (ADR-0008). |
| `tid` | TEXT | Tenant id. Updated on every upsert because a dual-audience future may legitimately change it. |
| `audience` | TEXT | `'workforce'` \| `'customer'`. Hardcoded to `workforce` in v1 per ADR-0008's simplification; will read from session/claims when External ID activates. |
| `username` | TEXT | Updated on every upsert (Entra-side rename possible). |
| `display_name` | TEXT | Same. |
| `first_seen_at` | TIMESTAMPTZ | Set once at first sign-in via DEFAULT NOW(); **never overwritten** thereafter. Enables "users since <date>" without joining anything. |
| `last_seen_at` | TIMESTAMPTZ | Updated on every upsert. Enables "most recently active" without scanning `audit.events`. |

Indexes:
- `last_seen_at DESC` — admin default sort.
- `username` — prefix filtering.

Migration in [`prisma/migrations/20260514192014_users_directory/`](apps/portal-bff/prisma/migrations/20260514192014_users_directory/migration.sql).

## [`UserDirectoryService`](apps/portal-bff/src/users/user-directory.service.ts)

```ts
async recordSignIn(entry): Promise<void> {
  try {
    await prisma.user.upsert({
      where: { oid },
      create: { oid, tid, audience, username, displayName },
      update: { tid, audience, username, displayName, lastSeenAt: new Date() },
    });
  } catch (err) {
    // logged, never propagated
  }
}
```

**Best-effort write.** Catches its own errors, logs a Pino warn (`user_directory.record_sign_in_failed`), returns `undefined`. The directory is a convenience for admin browsing, not a security boundary — a Postgres hiccup must not lock a user out of sign-in. ADR-0013's "no audit ⇒ no action" applies to the audit module only.

## [`SessionEstablisher`](apps/portal-bff/src/auth/session-establisher.service.ts) wiring

The directory call lands right after the existing audit emission:

```ts
await this.audit.signIn({ actor: user, sessionId: req.sessionID }); // blocking per ADR-0013
await this.userDirectory.recordSignIn({ ...user, audience: 'workforce' }); // best-effort
this.logger.log(...);
```

Two invariants the tests pin:

1. **Audit-first**: when `audit.signIn` throws, `userDirectory.recordSignIn` is NOT called. The directory never holds a row for a sign-in the audit log doesn't carry.
2. **Awaited**: an admin who just signed in sees themselves on the user list immediately — no race between the upsert and the response.

## Module wiring

[`UsersModule`](apps/portal-bff/src/users/users.module.ts) is declared `@Global()` so `SessionEstablisher` (which lives in `AuthModule`) injects `UserDirectoryService` without forcing `AuthModule` to import `UsersModule`. The directory is a true cross-cutting concern: one writer (the auth callback) and one future reader (the admin endpoint).

Wired into [`AppModule`](apps/portal-bff/src/app/app.module.ts) alongside the other v1 modules. `auth.module.spec.ts` updated to also import `UsersModule` in its slice-of-graph compile (otherwise the test fails to resolve the new `SessionEstablisher` dep).

## Notes for the reviewer

- The directory write **awaits** (not fire-and-forget). The cost is one round-trip per sign-in on the response-critical path; the benefit is the no-race property called out above. If sign-in p95 becomes an issue we can revisit (e.g. background job) but the simpler shape is correct first.
- `firstSeenAt` is intentionally absent from the `update` payload. The Prisma upsert's `update` block is precisely what changes on conflict; omitting the field leaves it untouched at the column level (Postgres-side default doesn't refire on UPDATE).
- The model lives in `public`, not in a dedicated `identity` or `cms` schema. ADR-0020 enumerates `cms.*` for editorial data and `audit.*` for the audit ledger but doesn't require a separate schema for user-directory data. We can promote it to its own schema later if a role-isolation need emerges; the migration would be a `ALTER TABLE users SET SCHEMA …`.
- `audit.events.actor_id_hash` is **not** stored on `public.users`. A future admin endpoint that joins sign-in counts from `audit.events` can compute the hash on-the-fly via `HashUserIdService` — keeping the salted-hash invariant from ADR-0013 intact (the salt stays inside the audit module).

## Test plan

- [x] `pnpm nx test portal-bff` — **365 specs pass** (was 358; +7: UserDirectoryService 4, SessionEstablisher integration 3).
- [x] `pnpm exec nx affected -t format:check lint test build --base=origin/main` — clean (the pre-existing rate-limit warnings + one unused-eslint-disable from PR #137 are unrelated).
- [x] Prisma `migrate diff` confirms the model matches the migration SQL.
- [ ] e2e — after merge: sign in via portal-shell or portal-admin, expect a row in `public.users` with the right `oid` / `last_seen_at`; sign in again, expect the same row's `last_seen_at` to advance and `first_seen_at` to stay put.

## What's next

The chantier sequence:

1. **This PR** — write side: schema + service + sign-in upsert.
2. **PR 2** — BFF `GET /api/admin/users` (paginated + filterable, gated by `@RequireAdmin`, emits `admin.users.query` audit).
3. **PR 3** — portal-admin `/users` screen (table + filter form), promote the sidebar entry from "Soon" badge to live link.

julien 02ac44e498 feat(portal-bff): audit log foundation per ADR-0013 (#76)
CI / check (push) Successful in 1m52s
CI / commits (push) Has been skipped
CI / scan (push) Successful in 1m7s
CI / a11y (push) Successful in 52s

## 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.
