Subject: [PATCH 01/18] feat(auth): move the SPA to BFF sessions (I2) and drop
 oidc-client-ts (BF1)

- src/auth/: GET /bff/user, login by navigation to /bff/login?returnTo=<same-origin path>, POST /bff/logout with X-CSRF then navigate to logoutUrl, /bff/config runtime config

- SDK 0.7.0 on /api/crud: credentials include, X-CSRF middleware, cacheScope from sub, onUnauthorized navigates to login; roles from /bff/user for UI only

- drop oidc-client-ts and react-oidc-context; Vite dev proxy for /bff, /api and /.well-known to the dev BFF on :8787; stories, stubs and tests follow

+
+The Node server in front of the SPA: a thin app around
+[`@craftainer/bff`](https://github.com/craftainer/lib-bff-ts) (OIDC login,
+server-side sessions in Valkey, the `/api/<name>/*` proxy, well-known
+endpoints, analytics intake, security headers, static files). It is a private
+pnpm workspace member (`pnpm-workspace.yaml`: `packages: [".", "bff"]`) with
+its own `package.json`, so the image can ship only its production
+dependencies (`pnpm --filter ./bff deploy --prod`).
+
+Node runs the TypeScript directly (type stripping): there is no build step.
+Use erasable syntax only (no `enum`, `namespace` or parameter properties) and
+`.ts` extensions on relative imports (`bff/tsconfig.json` enforces both). `bff/` is not part of the root
+`tsc -b`; it has its own `tsconfig.json`.
+
+## Files
+
+- `src/main.ts`: `loadConfig(process.env)`, `buildApp`, `listen` on
+  `BFF_HOST:BFF_PORT` (default `0.0.0.0:8080`).
+- `src/app.ts`: `buildApp(config, opts?)` calls `createBff` and registers this
+  app's own routes (one example, `GET /bff/ping`).
+- `src/app.test.ts`: smoke test, run by the root `vitest run`. It builds the
+  app in process with the library's in-memory session store, so it needs
+  neither Valkey nor an IdP.
+
+## Commands (from the repo root)
+
+```sh
+pnpm dev:bff        # node --watch src/main.ts
+pnpm start:bff      # node src/main.ts
+pnpm typecheck:bff  # tsc -p bff
+```
+
+The server needs its configuration in the environment (`PUBLIC_ORIGIN`,
+`OIDC_ISSUER`, `OIDC_CLIENT_SECRET`, `SESSION_STORE_URL`, and the optional
+variables); `loadConfig` lists every problem at startup. The variables are
+documented in the library's README.
+
+## What belongs here, and what belongs in the library
+
+Here:
+
+- App-specific routes (register them in `src/app.ts`, before `listen`).
+- Values this app chooses: upstreams (`BFF_UPSTREAMS`), analytics settings,
+  the options passed to `createBff`.
+- Wiring and tests for those.
+
+In `@craftainer/bff`, not here:
+
+- Anything about how the BFF behaves: login, sessions, CSRF, headers, the
+  proxy, health, well-known, analytics, static files.

+If the BFF's behaviour is wrong or missing something, fix it in `lib-bff-ts`
+and release a patch version, then bump the exact version in
+`bff/package.json`. Do not patch around it or copy library code into `bff/`.

+
+One subdirectory per supporting service (here: the BFF's Valkey session
+store). Each contains:
+
+- `compose.yml` — the Compose fragment for that service.
+- `README.md` — what it is, connection details, and how to remove it.
+- `<service>.env` — local-dev-only default credentials, only for a service
+  that has some (Valkey here has none).
+
+Every fragment is listed in `../compose.instance.yml`'s `include:` list, so
+all of them start together. A fragment's relative paths resolve against
+that fragment's own directory.
+
+## Devcontainer stack pattern
+
+`../compose.instance.yml` configures the app service (`myapp`, defined in
+the template-owned `../compose.yml`) and pulls every supporting service in
+via its `include:` list, not via `devcontainer.json`'s `dockerComposeFile`.
+
+No fragment here declares a `ports:` mapping or a `networks:` block:
+
+- **No `networks:`** — every service reaches every other one by its service
+  name on the default network Compose generates for this project.
+- **No `ports:`** — these services are reached only from other containers.
+  A host-reachable port goes in `forwardPorts`/`portsAttributes` in
+  `../devcontainer.json` instead.
+
+Every fragment's service defines a `healthcheck:`, and `myapp` lists a
+matching `depends_on: <service>: condition: service_healthy` entry, so
+nothing runs against a service that is still starting. Verify a healthcheck
+against the real pinned image rather than assuming `curl`/`wget` exist.
+
+## Do
+
+- Give a new service its own subdirectory with `compose.yml` + `README.md`,
+  a `healthcheck:`, and a `depends_on` entry on `myapp`.
+- Pin an image tag to the app version only (`valkey/valkey:9.1.2-alpine`),
+  not the OS sub-patch.
+
+## Keeping the architecture doc current
+
+Adding or removing a stack service, or changing how one connects, makes
+`../../docs/architecture.md`'s diagram stale — update it in the same change.
+
+## Don't
+
+- Add a `ports:` entry to any fragment here.
+- Reuse another service's volume or hostname.
+- Put real credentials in a fragment — local-dev-only defaults only.

+# valkey
+
+[Valkey](https://valkey.io/) (the Linux Foundation's BSD-3-Clause Redis
+fork, same wire protocol) holds the BFF's server-side sessions and login
+transactions (`bff/`, `@craftainer/bff`).
+
+- Compose file: `compose.yml`
+- Image: `valkey/valkey:9.1.2-alpine`
+- Host (from other containers only — see root README's "Don't"): `valkey`
+- Port (container-internal): `6379`
+- Connection URL: `redis://valkey:6379` (the scheme is the protocol name)
+- Data volume: `valkey-data` (append-only persistence enabled)
+
+## Plaintext in the dev stack
+
+The BFF refuses a plaintext `redis://`/`valkey://` session-store URL for any
+non-loopback host unless `SESSION_STORE_ALLOW_PLAINTEXT` is set. This
+dev-only service is reached over the compose network without TLS, so
+`../../compose.instance.yml` sets `SESSION_STORE_URL=redis://valkey:6379`
+and `SESSION_STORE_ALLOW_PLAINTEXT=true` on `myapp`. A deployment must use
+`rediss://` and not set the opt-out.
+
+## Do
+
+- Reach this service from inside the devcontainer network rather than
+  publishing the port: `valkey-cli -h valkey` (or `redis-cli -h valkey`).
+
+## Don't
+
+- Publish this service's port to the host, or reuse these defaults
+  anywhere but local dev.
+
+## Removing this service
+
+Delete this directory, remove its entry from `../../compose.instance.yml`'s
+`include:` and `depends_on:`, and drop the session-store variables there.

Subject: [PATCH 05/18] feat(analytics): track(), page views from the
 UrlAdapter, consent hook (AN5)

- track() posts to /bff/analytics with X-CSRF, fire-and-forget, cool-down on failure
- page views derived from the crud-views UrlAdapter state (no ids or filters)
- useConsent over /bff/consent; unknown or failed state is treated as not granted

 fix BF4 nits, write the BFF docs (BF5a)

- App calls usePageViews() once; no consent UI
- Remove /config.js script and template; .env.example documents the dev BFF vars
- Runner FROM derives from NODE_VERSION/DEBIAN_VERSION (digest kept); bff tests out of the image
- compose.instance.yml: dev BFF env (PUBLIC_ORIGIN, OIDC_*, BFF_UPSTREAMS); 8081 port label
- ADR 0007 (supersedes 0001, 0002), ADR 0008, FR-0001, docs/architecture.md; README, scripts docs, 0003/0006 notes

-  `.env.example`) default to the backend's own devcontainer Keycloak
-  realm/client — no configuration needed for the same common case above.

+
+Also commonly set: `BFF_UPSTREAMS` (JSON allowlist, `crud` by default
+mounted at `/api/crud/*`), `OIDC_DISCOVERY_URL` (when the BFF reaches the IdP
+at another host than `iss`), `ANALYTICS_*` and `SECURITY_TXT_*`. Every

+# 0007. Adopt `@craftainer/bff`: cookie sessions behind a Node server, no tokens in the browser
+
+## Status
+
+Accepted. Supersedes [0001](0001-oidc-auth-matching-the-backend.md) and
+[0002](0002-same-origin-api-proxy.md).
+
+## Context
+
+Until now the browser ran the OIDC Authorization Code + PKCE flow itself
+(`react-oidc-context`), held the access token in JavaScript and sent it as a
+bearer token through an nginx `/api` proxy whose settings were rendered at
+container start by `envsubst` into `config.js` (ADRs 0001 and 0002). Three
+things made that a poor base for a template:
+
+- Tokens reachable from JavaScript are readable by any script that runs in
+  the page (OWASP A02/A07; the current OAuth browser-based-apps guidance and
+  RFC 10017 on the BFF pattern recommend keeping them out of the browser).
+- The nginx image could not hold a session, check `Origin`, serve
+  `/.well-known/*`, or receive analytics events, and the `envsubst` config
+  path was a second configuration mechanism next to Vite's.
+- The same server-side pieces are wanted by every UI template, so they belong
+  in a library (`@craftainer/bff`, repository `craftainer/lib-bff-ts`).
+
+## Decision
+
+We will run a Node server in front of the SPA, built from the library, and
+the SPA holds no tokens:
+
+- **Library plus a thin `bff/`.** `bff/` is a private pnpm workspace member
+  that calls `loadConfig(process.env)` and `createBff`, adds this app's own
+  routes and listens (`bff/README.md`). Behaviour (login, sessions, CSRF,
+  headers, proxy, well-known, analytics, static files) stays in the library; a
+  defect there is fixed in the library and released, not patched in `bff/`.
+  The version is pinned exactly in `bff/package.json`.
+- **Login.** The BFF is the confidential OIDC client (`bff`) of
+  template-fastapi's Keycloak realm. The browser holds one `__Host-Http-`
+  session cookie (`Secure; HttpOnly; SameSite=Strict`); sessions, refresh
+  tokens and login transactions live in Valkey. `PUBLIC_ORIGIN`, never the
+  `Host` header, derives `redirect_uri` and the Origin check.
+- **SPA contract.** `GET /bff/user` (401 means "navigate to `/bff/login`"),
+  `GET /bff/login?returnTo=`, `POST /bff/logout`, `GET /bff/config`. Every
+  `/api/*` request and every non-GET `/bff/*` request carries `X-CSRF: 1`.
+  Roles from `/bff/user` are for the UI only; the backend still authorises.
+- **API access.** `BFF_UPSTREAMS` is an allowlist; the default instance has
+  one upstream, `crud`, mounted at `/api/crud/*` (prefix stripped). The BFF adds
+  `Authorization: Bearer`, refreshing the token when needed. The browser never
+  sees it, and inbound `Authorization`/`Cookie` headers are never forwarded.
+  This keeps ADR 0002's reason: same origin, so no CORS on the backend.
+- **Dev.** Vite (5173) proxies `/bff`, `/api` and `/.well-known` to the dev BFF
+  (8787, `pnpm dev:bff`), whose environment comes from
+  `.devcontainer/compose.instance.yml`. The BFF reaches the sibling backend
+  (port 8000) and Keycloak (port 8080) through `host.docker.internal`, as
+  ADR 0002 set up. Valkey is a stack service (`.devcontainer/stack/valkey/`).
+- **Image.** `Dockerfile` builds the SPA and `pnpm --filter ./bff deploy
+--prod`, then runs `node src/main.ts` (type stripping, no build step) as
+  the unprivileged `node` user on a digest-pinned `node:*-slim` image, port 8080. npm, npx and corepack are removed from the runner. The smoke test is
+  `/health/live`, which needs neither Valkey nor the IdP.
+- **Configuration.** Required at runtime: `PUBLIC_ORIGIN`, `OIDC_ISSUER`,
+  `OIDC_CLIENT_SECRET`, `SESSION_STORE_URL` (`rediss://` outside the dev
+  stack). `loadConfig` lists every problem at startup. There is no
+  `config.js`, no `VITE_OIDC_*` and no `envsubst`.
+
+## Consequences
+
+- No access or refresh token is ever reachable from script, and sessions can
+  be ended server-side (logout, expiry, back-channel logout).
+- A deployment now needs Valkey (or a compatible store) and a client secret,
+  and its IdP must register `<PUBLIC_ORIGIN>/bff/callback` and the back-channel
+  logout URL. Losing Valkey signs everyone out.
+- The BFF is one more process to patch: library releases arrive through
+  Renovate as exact-version bumps.
+- Rate limits are in memory, per replica, until a Valkey-backed limiter is
+  shown to work. The visitor-token for analytics has the same replica limit.
+- Static serving and the security headers move from nginx into the library,
+  so the CSP is the library's; an app that needs a different one changes it
+  through the library.
+- Moving between hosts or origins changes `PUBLIC_ORIGIN` and the realm's
+  redirect URIs together. Image runs on a developer machine use host port 8081
+  (`8081:8080`), because 8080 is Keycloak.

+# 0008. SPA analytics: page views and events through the BFF, consent decided server-side
+
+## Status
+
+Accepted
+
+## Context
+
+The app wants privacy-preserving usage numbers (which admin views are used),
+without an analytics script from a third party, cookies set from JavaScript,
+or identifiers in the browser. The BFF already sees the request (IP, user
+agent, GPC and DNT headers) and owns the analytics intake (`POST
+/bff/analytics`, adapters `none`, `log`, `umami`, `otel`; `@craftainer/bff`
+ADR 0004), so the open questions were what the browser sends, who decides
+whether an event counts, and how page views work without a router (ADR 0006).
+
+## Decision
+
+- **The browser sends events, nothing else.** `src/analytics/track.ts`:
+  `track(name, props?, url?)` POSTs to `/bff/analytics` with `fetch`, using
+  `keepalive` and the `X-CSRF: 1` header (never `sendBeacon`, which cannot
+  carry the header). The name matches the dotted lower-case pattern, values
+  are scalars of at most 200 characters, and `url` is a bare path. The browser
+  sends no id, title, referrer or query string.
+- **Fail closed.** `track()` never throws into the UI, never retries, and stays
+  quiet for five minutes after a transport failure or throttling. It also skips
+  the request when `navigator.globalPrivacyControl` is true or Do Not Track is
+  `1`; the BFF drops such requests as well (`ANALYTICS_RESPECT_GPC`), so
+  neither side trusts the other.
+- **Consent is decided by the BFF.** The default mode is `implied`: events
+  count unless the visitor declined, the legitimate-interest posture that
+  fits an audience-measurement tool configured to the CNIL exemption
+  conditions (first-party, no cross-site tracking, no raw IP, short-lived
+  pseudonymous token, a purpose limited to audience measurement). The
+  choice lives in the BFF's `__Host-Http-consent` cookie: `1` granted, `0`
+  declined (`0` stops recording in every mode, including `implied`). The SPA
+  reads and sets it through `GET`/`POST /bff/consent` (`useConsent`); `null`
+  means unknown and is treated as "not granted" by the SPA's own sends. A
+  deployment that needs prior consent sets `ANALYTICS_CONSENT=opt-in` with no
+  SPA change.
+- **No ids in page paths.** There is no router, so a "page" is the pathname
+  plus the admin's resource and view from the `UrlAdapter` query state (ADR
+  0006), e.g. `/heroes/trash`. Record ids, filters and paging never leave
+  the browser; a record page reports `/heroes/record`. `usePageViews()` is
+  called once in `App` and sends one `page.view` per distinct reported path,
+  so a filter change sends nothing.
+- **Properties are allowlisted server-side** (`ANALYTICS_PROP_KEYS`, default
+  empty), so adding a property is a deliberate change on both sides.
+- **No consent banner yet.** The default needs none. Whether and how to ask
+  is a design decision for the maintainers; until then `useConsent` exists
+  with no UI.
+
+## Consequences
+
+- No cookie, storage entry or id is created by the SPA's analytics; the only
+  cookie is the BFF's consent cookie, and only when a choice is stored.
+- Page-view counts under `implied` consent include visitors who never saw a
+  choice; a deployment in a stricter setting must switch to `opt-in` and add
+  the UI first, or no events will be recorded.
+- `viewPath` sends the pathname as is, so a path containing an id would be
+  reported; the admin's paths do not. A router later must map routes to
+  templates before reporting.
+- Dev and CI default to `ANALYTICS_BACKEND=none`; pointing it at Umami
+  needs `ANALYTICS_ENDPOINT` and `ANALYTICS_SITE_ID`.

+- **Vite** serves the SPA and proxies `/bff`, `/api` and `/.well-known` to
+  the BFF without changing `Host` or `Origin`; the BFF checks `Origin`
+  against `PUBLIC_ORIGIN` (`http://localhost:5173`).
+- **The BFF** is `bff/` (a thin app around `@craftainer/bff`). Its dev
+  environment is in `.devcontainer/compose.instance.yml`.
+- **Valkey** (`.devcontainer/stack/valkey/`) holds sessions; it is reached
+  only from other containers, over plaintext, which is the dev-only opt-out.
+- **Keycloak and the API** belong to `template-fastapi` and are reached
+  through its forwarded ports. The browser is sent to Keycloak at
+  `localhost:8080`, which is also the `iss` in tokens (`OIDC_ISSUER`), while
+  the BFF itself reaches it at `host.docker.internal:8080`
+  (`OIDC_DISCOVERY_URL`).
+
+Forwarded to the host: 5173 (Vite), 8787 (dev BFF, the back-channel logout
+target) and 8081 (the production image, below).

+# FR-0001. Sign in and call the backend through the BFF
+
+## Status
+
+Implemented (the real-Keycloak end-to-end test is BF5's).
+
+## Description
+
+The system shall let a user sign in with the backend's identity provider
+and use the admin without any access or refresh token being available to
+the page's JavaScript. It shall also record anonymous page views without
+identifying the visitor, and it shall honour a browser's Global Privacy
+Control and Do Not Track signals.
+
+## Source
+
+The maintainers' decision to use the BFF pattern for the template family
+(`docs/plans/2026-10-bff-wellknown-analytics-owasp.md`). No stakeholder
+register exists yet. Prompted
+[ADR 0007](../adrs/0007-adopt-craftainer-bff.md) and
+[ADR 0008](../adrs/0008-spa-analytics-and-consent.md).
+
+## Acceptance criteria
+
+- An anonymous visit shows a sign-in prompt; "Sign in" navigates to
+  `/bff/login` and returns the user to the page they were on.
+- After sign-in the browser holds one session cookie that is `Secure`,
+  `HttpOnly`, `SameSite=Strict`, `__Host-` prefixed, and no token in
+  storage, cookies readable by script, or responses.
+- A request to `/api/crud/*` without `X-CSRF: 1`, or from another origin, is
+  refused; without a session it answers 401 and the SPA goes to sign-in.
+- "Sign out" ends the session server-side and the IdP's session; a logout at
+  the IdP (back-channel) ends the BFF session too.
+- A session that expires or whose refresh is rejected returns the user to
+  sign-in rather than showing errors.
+- The admin lists and edits records the user's roles allow; the backend
+  remains the only authorisation point.
+- `/.well-known/security.txt` and `/.well-known/gpc.json` are served when
+  configured.
+- Navigating the admin sends `page.view` events with paths that contain no
+  record id, filter or query; with `Sec-GPC: 1` or `DNT: 1` nothing is
+  recorded.

-Playwright end-to-end journey of the manifest-driven admin (ADR 0006), in a
-real browser against a running `template-fastapi` and its Keycloak.
+Playwright end-to-end tests of the production topology (ADR 0007): the built
+SPA served by the BFF (`bff/src/main.ts`, a thin app around
+`@craftainer/bff`), signing in through a **real Keycloak** login form, with
+sessions in a **real Valkey** and the `/api/crud` proxy in front of a **real
+`template-fastapi`**. Nothing is mocked and nothing is token-aware in the
+browser.
 
+- `lane.sh` — brings the backing services up and down (below).
 - `run.sh` — runs the suite in the pinned Playwright image (the one
-  `tests/visual/run.sh` uses) with `--network host`. The config builds the app
-  and serves it with `vite preview`, whose `/api` proxy points at
-  `E2E_API_PROXY_TARGET` (default `http://localhost:8000`). Keycloak's host
-  name is resolved on the host and handed to the container; the browser signs
-  in through its real login form as the dev realm's `maintainer`.
-- `admin.e2e.ts` — the journey: sign in, create, inline and form edits (both conditional), a 412 after
-  an out-of-band change, archive and the trash, statistics.
-- `playwright.config.ts` — config; `*.e2e.ts` (not `*.spec.ts`, which Vitest
-  would pick up).
+  `tests/visual/run.sh` uses).
+- `playwright.config.ts` — config. Its `webServer` starts two BFFs from this
+  repo's `bff/` (`node bff/src/main.ts`, logs to `/tmp/bff-*.log`): `main` on
+  `http://localhost:8081` (long sessions, `ANALYTICS_BACKEND=log`,
+  `SECURITY_TXT_CONTACT`, `CHANGE_PASSWORD_URL`) and `short` on
+  `http://localhost:5173` (`SESSION_IDLE_SECONDS=6`,
+  `SESSION_ABSOLUTE_SECONDS=15`). Those two origins are the ones the realm's
+  `bff` client allows as redirect URIs. `*.e2e.ts`, not `*.spec.ts`, which
+  Vitest would pick up.
+- `global-setup.ts` — before the run, sets the realm's access-token lifespan to
+  40 s (the BFF refreshes within 30 s of expiry) and points the `bff` client's
+  back-channel logout URL at the BFF under test; afterwards it restores both.
+- `lane.ts` — helpers: sign-in through the Keycloak form, the session cookie, a
+  bare RESP client for the lane's Valkey (`GET sess:<id>`), the BFF log
+  reader, Keycloak's admin API.
+- `lane.compose.yml` — the override that makes template-fastapi's `myapp` run the
+  API.
+- The specs, by what they settle:
+  - `session.e2e.ts` — the `__Host-Http-session` cookie's attributes (`HttpOnly`,
+    `Secure`, `SameSite=Strict`, `Path=/`, no `Domain`), that the browser holds no
+    token, `GET /bff/user`, the security headers and SPA fallback, 401s and a
+    forged cookie, a missing `X-CSRF` (403 `csrf_rejected`), a foreign `Origin` or
+    `Sec-Fetch-Site` (403 `origin_rejected`), no CORS, and logout (cookie cleared,
+    session gone from Valkey, the refresh token revoked at Keycloak, the Keycloak
+    SSO session ended).
+  - `backchannel.e2e.ts` — an admin logout of a user at Keycloak ends that user's
+    BFF sessions (two browsers, two `sid`s) through the signed logout token, and
+    the endpoint refuses anything unsigned without needing `X-CSRF`.
+  - `refresh.e2e.ts` — an expiring access token is refreshed once under eight
+    racing requests: `sess:<id>` goes from `version` 0 to 1 (the Lua
+    compare-and-set against Valkey), with rotated tokens and the lock released; a
+    refresh Keycloak rejects ends the session.
+  - `expiry.e2e.ts` — the idle timeout (a sliding Valkey TTL) and the absolute
+    timeout, on the `short` BFF.
+  - `wellknown.e2e.ts` — `security.txt`, `change-password` (302), `gpc.json`,
+    `api-catalog`, the JSON 404, `/bff/config`, `/health/*`.
+  - `analytics.e2e.ts` — `POST /bff/analytics`: empty 202 for an accepted and for a
+    dropped event (`Sec-GPC: 1`, `DNT: 1`, consent cookie `0`), 400 for a prop key off
+    the allowlist and other malformed events, 413 above 16 KB, 403 without
+    `X-CSRF`; and the SPA's page views carry bare paths such as
+    `/heroes/trash`, never ids or queries.
+  - `admin.e2e.ts` — the manifest-driven admin (ADR 0006) through the BFF: create,
+    conditional inline and form edits, a 412 after an out-of-band change, archive
+    and the trash, statistics.

+`lane.sh up` runs `docker compose` over template-fastapi's
+`.devcontainer/compose.yml` and `compose.instance.yml` plus `lane.compose.yml`
+with `--no-deps` (its `depends_on` also lists Selenium). The suite's container
+joins **Keycloak's network namespace** (`--network container:<keycloak>`), so
+`localhost:8080` is Keycloak for the browser, the BFFs and the tokens' `iss`
+alike, and Keycloak can call the BFF's back-channel logout on `localhost:8081`.
+A lane has no VS Code to forward ports, which is why this repo's
+devcontainer setup (`host.docker.internal`) is not reused. The API and Valkey are
+addressed by container IP, which `run.sh` looks up.
 
 ```sh
-E2E_API_PROXY_TARGET=http://localhost:8000 tests/e2e/run.sh
+# 1. The SPA the BFF serves.
+pnpm exec vite build
+# 2. A clean, git-only checkout of template-fastapi's main (the realm with the
+#    `bff` client is in it), outside any workspace that is in use.
+E2E_FASTAPI_DIR=/path/to/template-fastapi-checkout tests/e2e/lane.sh up
+# 3. The suite.
+tests/e2e/run.sh            # extra arguments go to `playwright test`
+# 4. Everything down: containers, volumes and the built API image.
+E2E_FASTAPI_DIR=/path/to/template-fastapi-checkout tests/e2e/lane.sh down
 ```
 
-The backend must be configured with the same Keycloak host name the browser
-uses (`http://keycloak:8080/realms/template-fastapi`, the default of
-`E2E_OIDC_AUTHORITY`), because it checks the token's issuer. The journey
-creates and archives one record per run and never deletes or truncates
-anything else.
+The lane needs about 2 GB of memory (Keycloak alone is about 0.6 GB; the API,
+Postgres, RustFS, Valkey, Mosquitto and the Playwright container with Chromium
+make up the rest), so keep other heavy work off the machine while it runs. The
+suite itself takes roughly 5 minutes; the first `lane.sh up` also builds
+template-fastapi's devcontainer image and runs `uv sync`. The journeys create and
+archive one hero per run and never delete or truncate anything else; `down -v`
+discards the database anyway.
 
 ## Do
 
-- Keep it to journeys that need the real backend; component states belong in
-  stories and `src/**/*.test.tsx`.
+- Keep it to journeys that need the real Keycloak, Valkey or backend; component
+  states belong in stories and `src/**/*.test.tsx`, and the BFF's own logic in
+  `@craftainer/bff`'s tests.
+- Use `raw()` from `lane.ts` for requests that must control every header
+  (`Cookie`, `Origin`, `Sec-Fetch-Site`, `X-CSRF`) instead of Playwright's cookie
+  jar, and `idle(page)` before waiting on session timeouts: the SPA polls, and a
+  poll counts as activity.
+- Give each spec its own dev-realm user where it ends sessions at Keycloak (the
+  back-channel spec owns `viewer`).
 
 ## Don't
 
-- Run it in `prek` or the unit-test job: it needs the backend and Docker.
+- Run it in `prek` or the unit-test job: it needs Docker and a lane.
+- Work around a defect of `@craftainer/bff` here or in `bff/`. A failing test that
+  shows one goes back to `lib-bff-ts` as a fix and a patch release.

Subject: [PATCH 11/18] fix(analytics): report the admin's default resource
 when the URL names none (BF5b)

- viewPath takes a default resource; the admin publishes resources[0] via src/analytics/defaultResource.ts
- usePageViews keeps the last path in a ref so the late default does not duplicate a view
- remove the trash test.fail marker and its Known-failures entry; README e2e line points at lane.sh

   redirect URIs together. Image runs on a developer machine use host port 8081
   (`8081:8080`), because 8080 is Keycloak.
+
+## Amendment: the CSP style nonce (BF5c)
+
+The library's fixed `style-src 'self'` blocked Emotion's runtime `<style>`
+tags, so the SPA rendered unstyled behind the BFF. From `@craftainer/bff`
+0.2.0 the library serves the SPA's HTML with a per-request nonce, and the SPA
+passes it on:
+
+1. `vite.config.ts` sets `html.cspNonce: "__CSP_NONCE__"`. Vite adds that
+   value to its own `<script>` and `<link>` tags and emits
+   `<meta property="csp-nonce" nonce="__CSP_NONCE__">`.
+2. The BFF replaces every `__CSP_NONCE__` in `index.html` per request and
+   sends `style-src-elem 'self' 'nonce-<n>'; style-src-attr 'unsafe-inline'`
+   (`script-src 'self'` is unchanged), with the HTML `no-store`. Other
+   responses keep the old CSP. The library's ADR 0005 has the reasoning.
+3. `src/theme/emotionCache.ts` reads the nonce from the meta tag's `.nonce`
+   property (browsers hide the attribute from `getAttribute`) and builds the
+   Emotion cache with `{ key: "mui", nonce, prepend: true }`, per MUI's CSP
+   guide. `ThemeProvider` wraps the app in `CacheProvider`.
+
+`style-src-attr 'unsafe-inline'` stays because MUI and the data grid set
+`style=""` attributes, which a nonce cannot cover. Under `vite dev` the
+placeholder stays literal and no CSP is enforced; with no meta tag (unit
+tests, Storybook) the cache simply has no nonce.
