"""Self-contained web-stack feature tests: app + fake saddle daemon.

Unlike integration_test.py (which needs a real saddle daemon and a mock
LLM), this suite spawns everything it needs:

- the clanker-saddle app binary (path from argv[1], or builddir default)
  in a scratch directory with its own web-config.json (statum keys copied
  from the repo, plus `saddle_callback_base_url`) and SQLite database
- in-process fake saddle daemons speaking the wire contract: POST
  /register (plan 10: receives {saddle_token, web_base_url}, answers
  {ok, ssh_public_key, version}), POST /wake (records the wake; the
  daemon then asks POST /api/saddle/next-task), POST /task-update
  (cancel/comment/subtask-status), GET /status (scripted reflection —
  exceptional use only), and the phase-2 push channels home:
  POST /api/saddle/chunks (raw PTY batches) and POST /api/saddle/results
  (round entries + state transitions). The retired /start, /output and
  /log routes 404 like a post-phase-2 daemon.

It then drives the app the way statum.js does (entrypoint loads + action
POSTs) and asserts the Workstream B features against the wire contract:

3. plan-review blocks hide their duplicate body preview
5. rules CRUD/attach + the effective `rules` array in assignments
6. project notes, POST /api/saddle/note, `project_notes` + `callback`
   in assignments
   plus the raw-log side: pushed chunks -> session_raw_log + terminal
   raw view

Plan 10 phase 1 (work acquisition flip):

- per-saddle tokens: registration mints + /register-delivers them,
  legacy tokens migrate onto the row at startup, removal revokes
- token auth on every /api/saddle/* endpoint
- next-task allocation: concurrent asks race exactly one winner,
  affinity pinning for parked tasks, resume_notice on suspended resumes
- dispatcher: wake -> ask -> allocate roundtrip, the lost-wake guard
  (no ask after a wake -> offline, re-wake the next capable), and the
  pre-flip /answer + /start resume paths kept as the rollback route

Plan 10 phase 2 (telemetry flip):

- pushed chunks: idempotent on (session_id, seq), ordered, landing in
  session_raw_log so the SSE terminal keeps working
- pushed results: entries store like the /output path did (redelivery
  idempotent on the daemon entry ids), blocked raises the block row +
  parks + bumps the pulse (sealed refresh shows it), done/failed
  complete/fail the task, suspended parks for the affinity resume
- answer resumes, both daemon shapes: a SLEEPING affine saddle (its
  post-park ask returned 204) is woken, its ask allocating the resume
  with the verdict riding the assignment; a daemon parked MID-ROUND
  (its round holds the block's answer wait open, so it can never ask)
  gets the verdict delivered into that wait via POST /answer — same
  session, no wake. A daemon dying with a parked-with-answered task
  never requeues it: the verdict and session survive for the resume
- staleness: a silent runner gets ONE exceptional GET /status probe —
  alive keeps it running, dead requeues the task with a bot comment and
  marks the saddle offline; a recovered daemon's ask flips offline rows
  back to idle
- the deleted layers are gone: /output, /log and /start 404 on the
  daemon side, and nothing on the web side calls them

Plan 10 phase 3 (capability awareness + UI):

- assignment capability context: {saddle_tags, fleet_tags} on every
  payload, GET /api/saddle/capabilities (per-saddle token) feeding
  the daemon's `saddle capabilities` CLI
- subtask callback capabilities: explicit-only attachment validated
  against the operator tag set, unknown tags rejected with the valid
  list in the error
- task page: status block pinned to the top, blocking sections
  newest-first (sealed GET state)
- home dashboard: pinned OPEN blocks as newest-first link-through
  cards (no inline answer forms) above the cross-task activity
  timeline (last ~50 events newest-first)
- lost-wake-guard regression: a saddle that asks SLOWLY after its
  wake (busy winding down) still claims the task — the wake is never
  silently dropped, no re-wake storm fires, and the never-asks guard
  path (offline + re-wake of the next capable) stays green

Prints PASS/FAIL lines Statum-style; exits non-zero on any failure.

Plan 11 task D+E (UI + notifications), the `push` shard:

- task page: progress feed above the status card, status + description
  in a 50/50 grid, edit expander under the history expander, plan
  behind an expander, answered blocks behind an expander; queue screen:
  New Task expander above the filters; dashboard waiting-on-drafts
  block with links to where Enqueue lives (pages shard)
- real Web Push over VAPID: keypair generated at startup into
  web-config.json, GET /sw.js service worker with click-through,
  subscribe/unsubscribe + per-task Notify me actions, block events and
  waiting-on-drafts pushed globally, first start/failure/completion to
  opted-in users, best-effort queue with dispatcher-tick retry, 410/404
  endpoint pruning — payloads verified protocol-level (RFC 8291
  decryption + ES256 JWT signature) because the harness owns the
  browser-side keys

Heredoc completion reports (pages shard):

- terminal tasks render tasks.summary (set by done/fail) as a
  markdown completion-report card below the status/description grid —
  "Completion report" when done, "Failure summary" when failed, no
  card when empty; the summary renders through the shipped
  stm-markdown renderer (headings/code, no syntax leaks, HTML
  escaped) and the dashboard timeline snippets its first line

Speed pass (plan 11, task 0):

- SHARDING: the scenario groups are partitioned into seven independent
  bundles (pages, dispatch, subtasks, lineage, allocation, lifecycle,
  answers), each running in its own process against its own app
  instance, fake daemons and SQLite database. The default invocation
  runs all bundles in parallel and aggregates the verdicts and check
  counts into one exit code — meson sees a single green/red test.
  `--bundle NAME` runs one shard for debugging; WEBSTACK_SEQUENTIAL=1
  runs them in-process, one after another.
- Within a bundle, scenario groups SHARE the app+daemon instance and
  carry per-group state as database rows (task/session/block
  fixtures), never process restarts; the one deliberate restart (the
  startup token migration) lives in the answers bundle.
- EVENT-DRIVEN WAITS: wait_for polls at 50ms; the fixed sleeps were
  converted either to observable-condition waits (daemon-side
  counters, e.g. failed-delivery hits) or to quiet_window() — a
  bounded negative-assertion poll that FAILS LOUDLY the moment the
  event it guards against happens (a sleep could silently pass).
- ENV KNOBS: SADDLE_DISPATCH_TICK_S=1 (dispatcher cadence; default 5
  in production), SADDLE_HTTP_TIMEOUT_S=2, SADDLE_LOST_WAKE_S=2,
  SADDLE_STALE_S=3, plus the fake daemon's scripted timings — the
  wire-traffic shapes stay realistic, just faster.
