## Summary

Make the SPAs reach the BFF as a **same-origin** call via an Angular dev-server `/api` proxy. Solves the "Backend unreachable" error surfaced during the ADR-0030 dockerised dev mode VM validation when the SPA is accessed from a remote browser (e.g. `http://<vm-ip>:4200/`), and bypasses CORS in dev altogether. Follow-up to the just-merged ADR-0030 implementation.

## Root cause it fixes

Before this PR, both SPAs hardcoded `bffApiBaseUrl: 'http://localhost:3000/api'` (per ADR-0018) and the BFF's `CORS_ALLOWED_ORIGINS` only allowed `http://localhost:4200,http://localhost:4300`. Both assumptions hold for native `nx serve` (developer on the same machine as the BFF) but break the moment the browser sits on a different host than the BFF — exactly the case for the ADR-0030 `apps` Compose profile: open `http://<vm-ip>:4200/` from your workstation and the SPA's `localhost:3000` call hits your **workstation's** loopback (nothing there), not the VM's BFF. Even if the URL were right, the origin `http://<vm-ip>:4200` is not in the CORS allowlist.

## Fix

Switch to a same-origin dev pattern: the Angular dev-server proxies `/api/*` to the BFF, and `environment.ts` uses a relative `'/api'` URL.

| File | Change |
| --- | --- |
| `apps/portal-shell/proxy.conf.js` | **New.** Maps `/api → ${BFF_TARGET:-http://localhost:3000}` (JS form so the env var can swap the target at startup). |
| `apps/portal-admin/proxy.conf.js` | **New.** Same shape. |
| `apps/portal-shell/project.json`, `apps/portal-admin/project.json` | `serve.options.proxyConfig` points at the new file. |
| `apps/portal-shell/src/environments/environment.ts`, `apps/portal-admin/src/environments/environment.ts` | `bffApiBaseUrl: 'http://localhost:3000/api'` → `'/api'`. The comment block explains the rationale + how production siblings can still use an absolute origin if SPA + BFF live on different hosts. |
| `apps/portal-shell/src/observability/tracing.ts` | `new URL(environment.bffApiBaseUrl)` would throw on a relative URL — resolved against `window.location.origin` so both relative (dev) and absolute (prod cross-origin) bases work. |
| `infra/local/dev.compose.yml` | `BFF_TARGET=http://portal-bff:3000` added to `portal-shell` and `portal-admin` so the proxy hits the BFF **container** by name (Compose DNS) when the `apps` profile is up. Native `nx serve` leaves the var unset and falls back to `localhost:3000`. |

## Why a relative URL is safe

- `${bffApiBaseUrl}/health` etc. compose to `/api/health` — relative paths work in `fetch` / `HttpClient`.
- `tracing.ts` propagates `traceparent` on requests whose origin matches the BFF origin. Resolving the relative base against `window.location.origin` gives the current page's origin, which is exactly the origin the dev-server proxy serves from — so the regex still matches the right requests in dev. In a future cross-origin production deployment, `environment.prod.ts` can set an absolute `bffApiBaseUrl`; the URL constructor's second arg is ignored when the first is absolute, so the same code path keeps working.
- Auth flow (`feature-auth` / `auth.config.ts`): consumes `bffApiBaseUrl` via DI as a string prefix — agnostic to absolute vs relative.

## Scope notes

- The OTel HTTP exporter (`environment.otlpEndpoint = 'http://localhost:4318/v1/traces'`) and the cross-SPA links (`adminAppUrl`, `shellAppUrl`) **remain absolute**. They hit the same remote-browser problem on `apps`-profile access, but neither is blocking the user-visible "Backend unreachable" path this PR targets. Out of scope here; a follow-up could either proxy them too or surface them via runtime config.
- This pattern is dev-server only — production builds do not use the proxy. Per-environment `bffApiBaseUrl` overrides remain the supported lever (ADR-0018), unchanged.

## Test plan

- [x] `docker compose -f dev.compose.yml --profile apps config` still validates.
- [ ] **On the VM**, `./infra/local/dev.sh up apps`, then in the workstation browser open `http://<vm-ip>:4200/` → SPA loads, the "Backend unreachable" message is gone, network tab shows `/api/...` calls succeeding (same-origin, no CORS preflight).
- [ ] Native `nx serve portal-shell` still works (the proxy falls back to `localhost:3000`).
- [ ] Trace headers (`traceparent`) appear on `/api/*` fetches in the browser network tab.
- [ ] `pnpm exec nx affected -t test build` green on the two SPAs.

## Related

- [ADR-0030](docs/decisions/0030-dockerised-dev-mode.md) — the dockerised dev mode this enables to actually work from a remote browser.
- [ADR-0018](docs/decisions/0018-environment-configuration-strategy.md) — the `environment.ts` per-env strategy this complements (does not supersede — production behaviour unchanged).

julien 0435fec10a feat(portal-admin): jaeger deep link on trace_id + actor-pivot on actor_id_hash (#166)
CI / check (push) Successful in 2m35s
CI / commits (push) Has been skipped
CI / scan (push) Successful in 1m26s
CI / a11y (push) Successful in 1m49s
CI / perf (push) Successful in 3m48s
## Summary

Turns the audit-log table's `trace_id` and `actor_id_hash` columns from inert text into the two pivots an investigator actually needs:

- **trace_id** → Jaeger deep link (opens in a new tab). Closes the "join audit + traces by trace_id" loop from [ADR-0012](docs/decisions/0012-observability-pino-opentelemetry.md) / [ADR-0013](docs/decisions/0013-audit-trail-separated-postgres-append-only.md) without any new BFF surface.
- **actor_id_hash** → click to refilter the table on that single actor. "Show me everything else this user did" stays in the page; no copy-paste loop.

## What lands

### Trace-id deep link to Jaeger

[`audit.html`](apps/portal-admin/src/app/pages/audit/audit.html#L162-L173) — the cell becomes an `<a target="_blank" rel="noopener noreferrer">` pointing at `${environment.jaegerBaseUrl}/trace/<traceId>`. Anonymous events (`traceId === null`) keep the dash placeholder.

[`environment.ts`](apps/portal-admin/src/environments/environment.ts) gains `jaegerBaseUrl`. Dev defaults to `http://localhost:16686` (matches the compose `observability` profile from `infra/local/dev.compose.yml`). Per-env replacement picks up whatever trace backend the future infrastructure ADR settles on — Tempo, Grafana Cloud, on-prem Jaeger; the SPA-side wiring doesn't care.

### Actor-pivot click

[`audit.html`](apps/portal-admin/src/app/pages/audit/audit.html#L146-L160) — non-null `actorIdHash` becomes a `<button>` styled to read inline like the hash text (`.actor-hash--clickable`: button reset + dotted-underline hover + brand-colored focus ring). Click → `filterByActor(hash)` sets the existing `actorIdHash` filter signal, resets offset to 0, and re-runs the query. Each pivot still emits its own `admin.audit.query` audit row server-side (per [ADR-0020](docs/decisions/0020-portal-admin-app.md)) so the drill is itself auditable.

Anonymous rows keep the `(anonymous)` plain-text rendering — there's no useful filter value to pivot on.

## Why not inline-expand Pino log lines under the row

Considered, deferred. The BFF's Pino output goes to **stdout only** today; standing up a queryable log aggregator (Loki, OpenSearch, …) is a separate infrastructure chantier with its own ADR. The Jaeger jump-off carries ~99 % of the investigator's needs anyway — the trace already contains span attributes (`db.statement`, `http.status_code`, exception events) for the same request scope; Pino lines on top of that would be redundant for most investigations.

When the log aggregator does land, the inline-expand model can come back as a follow-up: `GET /api/admin/logs?traceId=<id>` + an expand affordance on the same row. The current Jaeger anchor and the future inline-logs would naturally coexist (different drills, both surfaced on the same `trace_id`).

## Notes for the reviewer

- **Why a `<button>` for the actor cell rather than an `<a>`?** The action is an in-page filter change, not a navigation. Buttons keep keyboard activation (Enter / Space), don't pollute browser history, and screen readers announce "Filter the table on hash(jane), button" rather than a misleading link role.
- **Why the dotted-underline hover for the actor, but solid-underline for trace?** Different affordances. The trace anchor is a permanent link to an external resource (Jaeger UI), so the solid underline matches the universal "link" convention. The actor button is an inline pivot that *mutates state* — the dotted underline + hover-fill conveys "this does something subtle within the page" without screaming "link".
- **CSS guardrails preserved**: focus rings on both elements, brand-color tokens (light + dark), tap targets meet the AAA 44×44 minimum (the button reset preserves the line-height + the `cell-actor` padding ≥ 12 px on each side).
- **No new i18n strings.** `title` attributes are hover hints, not screen-reader-essential — the underlying hash + traceId are the actual semantic content. The "(anonymous)" string and the dash placeholder were already in the template.
- **No BFF change.** This whole PR is SPA-side only. The audit endpoint already returns `traceId` and `actorIdHash` in every row.

## Test plan

- [x] `pnpm nx run-many -t lint test build --projects=portal-admin` — green.
- [x] **54 portal-admin specs pass** (was 50; +4 for the four new behaviours).
- [x] Lazy `audit` chunk: 18.26 → ~18.5 KB raw / 4.44 KB gzip — comfortably under the per-chunk budget.
- [ ] **Manual smoke**:
  - Sign in to portal-admin with `Portal.Admin` → open `/audit`.
  - Click any trace_id → new tab opens at `http://localhost:16686/trace/<id>` (assuming `./infra/local/dev.sh up observability` is running so Jaeger is up).
  - Anonymous rows show `—` for trace, `(anonymous)` (plain text, not clickable) for actor.
  - Click any non-anonymous actor hash → the table refreshes filtered on that hash, the "Actor id hash" filter input above shows the same value, page jumps to offset 0.
  - Tab through a row: timestamp / event are plain text; outcome badge skipped (not interactive); actor button gets focus ring; trace link gets focus ring; payload `<details>` summary gets focus ring.

## Follow-ups (optional)

- When the log aggregator ADR lands, extend the trace cell to also offer an inline-expand of Pino lines for that trace. Jaeger anchor stays as the primary affordance.
- A similar treatment on the `/users` page (clicking a row's `oid` to "show me this user's audit trail") is the natural sibling. Defer until there's an investigator workflow that asks for it — premature otherwise.

julien ee51efb688 feat(portal): /api/me/capabilities + cross-app menu links + real role label (#151)
CI / scan (push) Successful in 2m13s
CI / commits (push) Has been skipped
CI / check (push) Successful in 3m48s
CI / a11y (push) Successful in 1m53s
CI / perf (push) Successful in 3m46s
## Summary

PR 3 of 3 — final piece of the user-menu / profile / cross-app chantier. Closes the loop with the BFF capabilities endpoint, symmetric cross-app entries in both user menus, and a real role label in place of the hardcoded "Anonymous" widget on the portal-shell sidebar.

| PR | Périmètre |
| --- | --- |
| PR 1  | Shared `UserMenu` dropdown + integration. |
| PR 2  | `/profile` pages on both apps. |
| **PR 3 (this one)** | `GET /api/me/capabilities` + real sidebar role label + cross-app menu entries. |

## What lands

### BFF — `GET /api/me/capabilities`

New [`MeModule`](apps/portal-bff/src/me/me.module.ts) wiring a single endpoint:

```ts
GET /api/me/capabilities → { canAccessAdmin: boolean }
```

Resolved against the user-portal session ([`portal_session`](apps/portal-bff/src/me/me.controller.ts) — the path-routed session middleware in `main.ts` already maps `/api/me/*` to that session). Returns 401 if no session is present, consistent with `/api/auth/me`. 5 specs cover the four state combinations + a regression-fence asserting the curated view never leaks the raw `roles` array.

### ADR-0009 amendment

[`docs/decisions/0009-auth-flow-oidc-pkce-msal-node.md`](docs/decisions/0009-auth-flow-oidc-pkce-msal-node.md) — new **"Curated public view"** section codifies the design stance the user picked when we agreed the staging:

> The `/auth/me` payload exposes a deliberately narrow projection of the session: `oid`, `tid`, `username`, `displayName`. **The raw `roles` claim is _not_ part of `/auth/me`** — it stays server-side […]. The SPA derives binary UX hints from a dedicated companion endpoint […]. The shape is intentional: the SPA can never reconstruct the raw role names from the curated view, so introducing additional internal-only roles […] does not widen the SPA-side surface.

The routes table grows a row for `/me/capabilities`.

### Portal-shell — capabilities-driven UI

- **New service** [`CapabilitiesService`](apps/portal-shell/src/app/services/capabilities.service.ts) (app-local, not in `feature-auth` — the admin app has its own roles channel via `/api/admin/auth/me` and would never use this). Signals: `capabilities`, `canAccessAdmin`. Fires `GET /me/capabilities` reactively via an `effect` that watches `auth.currentUser()`. Anonymous sessions short-circuit to the all-false default without a fetch — the BFF would 401 anyway.
- **Header** ([`header.ts`](apps/portal-shell/src/app/components/header/header.ts)) — `userMenuItems` is now a `computed`. Profile + Settings stay unconditional; **"Open Portal Admin"** appears only when `canAccessAdmin()` flips true, with `href = environment.adminAppUrl`. Per ADR-0020 the two SPAs live on distinct origins, so this is a raw cross-origin anchor, not a routerLink.
- **Sidebar** ([`sidebar.ts`](apps/portal-shell/src/app/components/sidebar/sidebar.ts) + [`sidebar.html`](apps/portal-shell/src/app/components/sidebar/sidebar.html)) — the hardcoded `Role: Anonymous` widget is replaced by a derived computed:
  - `Anonymous` when no session.
  - `Administrator` when `canAccessAdmin()` is true.
  - `User` otherwise (signed-in, no admin).

  The aria-label gains a `role` placeholder so screen readers hear the live value.

### Portal-admin — symmetric cross-app entry

- **Header** ([`header.ts`](apps/portal-admin/src/app/components/header/header.ts)) — adds an unconditional `Open Portal Shell` row pointing at `environment.shellAppUrl`. Anyone able to reach portal-admin can reach portal-shell, so no capabilities check needed; admins always benefit from a one-click jump back to the end-user surface.

### Environments

`adminAppUrl` and `shellAppUrl` added to the respective [`environment.ts`](apps/portal-shell/src/environments/environment.ts) files (dev defaults: `:4300` for admin, `:4200` for shell). Per-env siblings (staging / prod) will override the host once they exist, per ADR-0018.

### i18n

| Key | EN source | FR target |
| --- | --- | --- |
| `header.userMenu.openAdmin` | Open Portal Admin | Ouvrir Administration APF Portal |
| `sidebar.role.administrator` | Administrator | Administrateur |
| `sidebar.role.user` | User | Utilisateur |
| `sidebar.role.aria` | reshaped with `{role}` placeholder | reshaped likewise |

Admin-side strings stay in English source per ADR-0020.

## Notes for the reviewer

- **Why `CapabilitiesService` in the app, not in `feature-auth`?** Only `portal-shell` will ever call `/api/me/capabilities` — the admin SPA hits `/api/admin/auth/me` which already returns `roles`. Putting the service in `feature-auth` would publish a tree-shakable `providedIn: 'root'` injectable that ships in both bundles. Keeping it app-local makes the boundary explicit.
- **Why a `computed` for `userMenuItems` rather than mutating an array in an `effect`?** Signals + computed = single source of truth. The shared `UserMenu` re-renders automatically when the items list changes (whenever capabilities flips). Less ceremony than maintaining a `WritableSignal<UserMenuItem[]>`.
- **Why the `flushPendingEffects` test helper?** Zoneless apps rely on the signals scheduler to dispatch `effect()` callbacks via micro-task scheduling. `fixture.detectChanges() + whenStable()` once is not enough: the chain is `meReq.flush()` → `_state.set()` → effect scheduled → effect fires → `http.get()` queued. The helper loops 4× to give the scheduler enough rounds to settle before `expectOne(CAPABILITIES_URL)` looks up the request.
- **Why no test for the dev URL values?** `environment.ts` is config that gets swapped at build time per ADR-0018; the values themselves are environmental. Asserting the dev value in a test would lock in a port (4200/4300) that's separately configured in `project.json`.

## Test plan

- [x] `pnpm nx test portal-bff` — **401 specs pass** (was 396, +5 for `MeController`).
- [x] `pnpm nx test portal-shell` — **40 specs pass** (was 35, +5: 3 sidebar role-label + 2 header admin-link).
- [x] `pnpm nx run-many -t lint test build --projects=portal-shell,portal-admin,portal-bff,shared-ui,shared-state,feature-auth` — 18/18 tasks green, including the i18n-strict `portal-shell:build:production`.
- [ ] Manual smoke (with a `Portal.Admin`-assigned account):
  - Sign in on portal-shell → sidebar reads `Role: Administrator`, user menu lists `Open Portal Admin` at the bottom (right above the Sign-out separator), clicking the link opens `localhost:4300`.
  - Sign in on portal-admin → user menu lists `Open Portal Shell`, clicking opens `localhost:4200`.
  - Sign in on portal-shell with a non-admin account → sidebar reads `Role: User`, `Open Portal Admin` is absent.
  - Sign out → sidebar reads `Role: Anonymous`, the menu collapses to its anonymous-state Sign-in button.

## What's next

Chantier closed. The user-menu shape is now stable; further entries (notifications inbox, theme override, locale switcher inside the menu rather than the footer) plug into the existing `items` API without re-shaping the component.

## Summary

Phase-3a step per [ADR-0020](docs/decisions/0020-portal-admin-app.md) §"Confirmation" item 4 (entry route + admin shell). Wires the existing [`feature-auth`](libs/feature/auth) library against the distinct admin OIDC routes (`/api/admin/auth/*`) the BFF exposes since PR #129, ships a lean header/sidebar/footer chrome with an "Admin" badge so an internal user can never mistake the surface for portal-shell, and gives the landing page a self-test panel that confirms the auth chain end-to-end as soon as an `admin` Entra role gets assigned.

## What lands

### Lib change — `AUTH_PATH_PREFIX` injection token

[`libs/feature/auth`](libs/feature/auth/src/lib/auth.config.ts) gains one injection token. AuthService composes URLs as `${bffBaseUrl}${pathPrefix}/{me,login,logout}` instead of hard-coding `/auth/...`. Default factory returns `/auth`, so portal-shell-shaped consumers keep working without an explicit provider — no churn on existing call sites. Admin hosts override with `/admin/auth`.

The interceptors (`bffCredentialsInterceptor`, `csrfInterceptor`, `bffUnauthorizedInterceptor`) are **unchanged** — they only care about the BFF base URL, not the path prefix.

### portal-admin wiring

- [environment.ts](apps/portal-admin/src/environments/environment.ts) — same shape as portal-shell, same BFF base URL (both SPAs talk to one BFF per ADR-0020 §"Where does the admin app live"). Same CSRF cookie name in v1.
- [app.config.ts](apps/portal-admin/src/app/app.config.ts) — `HttpClient` with the standard interceptor chain (credentials → csrf → unauthorized), `AUTH_BFF_BASE_URL` from env, `AUTH_PATH_PREFIX = '/admin/auth'`, `AUTH_CSRF_COOKIE_NAME` from env.

### Admin shell

- **[AdminHeader](apps/portal-admin/src/app/components/header/header.ts)** — APF wordmark + persistent "Admin" badge + auth widget. No global search / notifications / help cluster: admins land on tabular workloads, not a discovery dashboard (ADR-0020 §"UX style is data-dense").
- **[AdminSidebar](apps/portal-admin/src/app/components/sidebar/sidebar.ts)** — static menu listing the four ADR-0020 v1 modules. Audit log is a live router link (target of the next PR); the others are `aria-disabled` placeholders with a "Soon" badge so the navigation shape is visible even before they ship.
- **[AdminFooter](apps/portal-admin/src/app/components/footer/footer.ts)** — copyright + persistent "Admin surface" tag. Stays in view for long workloads where the header has scrolled off.

### Home — auth self-test panel

[apps/portal-admin/src/app/pages/home/](apps/portal-admin/src/app/pages/home/):

- Signed-in: shows `displayName`, `username`, `tenant`, `oid` in a monospaced detail list.
- Anonymous: "No admin session detected" + a "Sign in via Entra" button that delegates to `AuthService.login()` → 302 through `/api/admin/auth/login`.
- Error: "Could not reach the BFF" + retry button.
- Roadmap list quoting ADR-0020's v1 catalogue.

## Known limitations (v1, documented)

- **CSRF cookie shared between surfaces.** Both portals issue `portal_csrf` on session creation. A user with both portals open will see overwrites on the second sign-in; mutating actions on the first surface will then 403 until refresh. Splitting to `portal_admin_csrf` is a follow-up if the pattern becomes common.
- **Shell chrome strings are plain English.** The admin app's `$localize` plumbing is wired (matches portal-shell), but adding markers to the shell here would require regenerating `messages.fr.xlf` and `i18nMissingTranslation=error` fails the prod build on every gap. Full admin i18n is its own follow-up.
- **`LayoutStateService` not yet consumed.** No collapse toggle in v1. Theme preference still threads through because both apps read the same `localStorage` key — toggle in portal-shell, see it honoured in portal-admin.
- **`ci:perf` only runs against portal-shell.** Admin perf budgets are enforced at build time by `apps/portal-admin/project.json` (`maximumError == maximumWarning` per ADR-0020's relaxed thresholds: 500 KB initial JS / 1.5 MB initial total). Adding admin to `pnpm ci:perf`'s gzip + Lighthouse chain is a follow-up.

## Test plan

- [x] `pnpm nx test feature-auth` — **29 specs pass** (was 28; +1 for the `AUTH_PATH_PREFIX` override).
- [x] `pnpm nx test portal-admin` — **15 specs pass** (was 1; +14: AdminHeader 5, AdminSidebar 3, AdminFooter 2, Home 4, App 1 expanded).
- [x] `pnpm exec nx affected -t format:check lint test build --base=origin/main` — clean.
- [x] Gzip-budget script run manually against `dist/apps/portal-admin/browser`: 86.65 KB initial / 300 KB budget, 4.46 KB CSS / 150 KB budget, 2.15 KB largest lazy / 100 KB per-chunk budget. Both `en` + `fr` bundles checked thanks to PR #133's multi-locale detection.
- [ ] e2e — pending an Entra `admin` role assignment. Once available: `pnpm nx serve portal-admin`, visit `http://localhost:4300`, see "No admin session detected", click "Sign in via Entra", complete the round-trip, land back on `/` with the signed-in payload + `portal_admin_session` cookie set.

## Notes for the reviewer

- `AdminHeader` is intentionally narrower than `Header` from portal-shell — no shared base class. The two are likely to evolve in different directions (admin-specific banner with system-status badges, audit-trail link, etc.) and a premature abstraction would be expensive to undo.
- `AdminSidebar`'s "Soon" badge is a deliberate signal — without it, an admin who clicked a placeholder link and got a route-not-found would assume the app is broken. The badge sets expectations.
- All shell components use `:host-context(.dark)` for dark-mode SCSS instead of `:host(.dark)` — same pattern as portal-shell, since the `.dark` class lives on `<html>` outside the component's view encapsulation.
