-- The SPA carries no token. Only the opaque session id cookie (`__Host-portal_session`) plus the CSRF cookie (`__Host-portal_csrf`, read by JS for double-submit).
+- **Two SPAs, one BFF.** `portal-shell` is the end-user surface; `portal-admin` is a separate Angular app on a distinct origin with its own bundle, sign-in flow, and session cookie (per ADR-0020). They share libs but never a runtime — an admin session is not silently authenticated to `portal-shell` and vice versa. The admin entry route is gated by an Entra `admin` app-role claim + `@RequireMfa({ freshness: 600 })` per ADR-0011.

- `traceparent` (W3C) propagates from the browser through the BFF to the downstream APIs — same `trace_id` end-to-end.
- The OTel Collector is the only piece coupled to the eventual on-prem observability backend. Choice of backend (Grafana Loki + Tempo, ELK, …) is deferred to the on-prem infrastructure ADR.

+- `portal-admin` is a v1 skeleton (per ADR-0020) — it currently imports no libs. Its planned dependencies on the `scope:shared` set are drawn dashed; they materialise as the admin modules land. No `scope:portal-admin` row exists in `eslint.config.mjs` yet; one lands when the admin modules grow real lib dependencies (follow-up).
+- Every Angular-flavoured shared lib (`shared-ui`, `shared-state`) lives under `scope:shared`, not `scope:portal-shell`. The naming was historically ambiguous; what matters is the tag in `project.json`, which gates lint-time enforcement.
+
Forbidden by the depConstraints (and lint-enforced) — examples:
-- `portal-bff` ⟶ `shared-ui` (back imports Angular code: scope clash).
-- `portal-bff` ⟶ `feature-auth` (back imports a frontend feature).
-- `shared-tokens` ⟶ `shared-ui` (a `type:shared` lib cannot reach a `type:shared` lib in a narrower scope, nor a feature lib).
+- `portal-bff` ⟶ `shared-ui` / `feature-auth` (`scope:portal-bff` may only reach `scope:portal-bff` + `scope:shared`; and the BFF runs in Node anyway, so Angular code is mechanically unusable).
+- `portal-shell` ⟶ `portal-admin` (cross-app — apps don't reach into each other; they communicate via the BFF).
+- `shared-tokens` ⟶ `feature-auth` (`type:shared` may only reach `type:shared`, so feature libs are off-limits).

+Notes:

+- **The BFF and SPA themselves are not in compose.** They run as local Node / Angular dev-server processes via `pnpm nx serve …`. Compose only hosts the runtime _dependencies_ — keeping the inner-loop edit/refresh fast. The Caddy `serve-static` profile is the production-shape exception: it lets you eyeball a prod build under the locale routing without standing up a real reverse proxy.
+- **Named volumes are intentional.** Wiping `down -v` is the supported reset path; the Postgres bootstrap SQL (audit schema + role grants per ADR-0013) only runs on a fresh data volume.
+- **The CI runners stack is separate** (`infra/ci-runners.compose.yml`, `name: apf-portal-ci-runners`) and lives on its own Docker network. Same host machine in v1, but co-located by convenience, not by coupling — they can move to a different host without touching the dev stack. The runners register with Gitea via `GITEA_RUNNER_REGISTRATION_TOKEN` on first boot and persist their credentials in `./data/runner-N/`.
+- **Ports listed are the host-side defaults.** All can be overridden through `infra/local/.env` (`POSTGRES_PORT`, `REDIS_PORT`, `OTEL_HTTP_PORT`, `JAEGER_UI_PORT`, `SERVE_STATIC_PORT`, …). The container-side ports never change.
