Admin-only crawler dashboard backed by an SSE live-status stream,
coordinated browser restart, runtime PHPSESSID refresh, dead-letter
requeue, and a batch of reliability fixes. Closes everything from
the two-pass audit (10 commits' worth) and bumps 0.52.0 -> 0.55.0.
Backend:
- New /admin/crawler/* surface (cookie-auth, RequireAdmin) split
into status / control / dead_jobs / backlog modules. SSE stream
composes in-memory status with DB-derived queue counts, memoizes
the counts for 1s and debounces watch pokes for 250ms (~10x QPS
reduction per subscriber). One-shot GET /admin/crawler shares the
same compose path.
- POST /admin/crawler/run gated by manual_pass_lock try_lock_owned
(409 Conflict on overlapping click); browser restart goes through
the coordinated_restart gate (drain + relaunch + auto-clear of the
sticky session_expired flag on Ok).
- Runtime PHPSESSID refresh via SessionController (allow-list
validation, never logged, audit row carries SHA-256 fingerprint).
Storage layer is repo::crawler::runtime_session_{load,persist}.
- Dead-letter requeue with four scopes (all/manga/chapter/job);
scope=all requires confirm:true; DISTINCT ON dedup keeps the
partial unique index from rejecting requeues for chapters with
multiple dead rows. SQL is four &'static str constants per scope.
- StatusHandle + ChapterGuard / CoverGuard RAII model survives
panics; last-writer-wins on cover so concurrent dispatches don't
clobber each other's slot. Pure functions (should_stop /
should_mark_clean_exit / should_abort_pass) with named regression
tests.
- Reliability bundle: per-lease heartbeat, jitter on retries,
per-job timeout, circuit breaker on consecutive failures, BrowserManager
coordinated restart gate, request fingerprint changes.
- Streaming page download: Storage::put_stream trait method,
LocalStorage impl atomic via temp + fsync + UUID-suffixed rename.
Pages stream through with peak memory ~one HTTP chunk + 64-byte
sniff prefix instead of one full image per dispatch.
- New partial indexes (migration 0022): mangas_missing_cover_idx
and crawler_jobs_dead_idx, both ordered by updated_at DESC to
match the dashboard's LIMIT/OFFSET reads.
- Security hardening: admin_csrf_guard (Origin/Referer allowlist
on /admin/* mutations, opt-in via ADMIN_ALLOWED_ORIGINS),
admin_no_store_guard (Cache-Control: no-store on admin
responses), audit rows carry per-scope target_id.
Frontend:
- /admin/crawler page decomposed into lib/components/crawler/
(11 components: ProgressBar, SearchBar, CrawlerHero,
CrawlerControls, ActiveChaptersCard, ActiveJobsTable,
MissingCoversTable, DeadJobsTable, RestartConfirmModal,
RequeueAllConfirmModal, SessionModal). Page is 532 LOC of
orchestration; each component 22-148 LOC.
- EventSource lifecycle wired to visibilitychange / pagehide /
pageshow (BFCache); after 5 consecutive errors probes the status
endpoint so a 401 routes through the global on401Hook instead of
infinite silent reconnects.
- Backlog $effect refetches debounced 500ms with per-loader
AbortControllers; refresh after a control action only runs when
the SSE stream is dead.
- Inline requeue button on /admin/mangas patches the affected row's
sync_state locally (no full chapter-list refetch); proper
aria-label. Requeue-all gets its own confirm modal; both confirm
modals autofocus Cancel.
- SvelteKit reverse proxy bypasses its 5-minute AbortController
for Accept: text/event-stream; pure shouldBypassProxyTimeout
helper covered by unit tests.
Config / docs:
- New env vars (.env.example): ADMIN_ALLOWED_ORIGINS,
CRAWLER_JOB_TIMEOUT_SECS, CRAWLER_METADATA_MAX_CONSECUTIVE_FAILURES,
CRAWLER_BROWSER_RESTART_THRESHOLD.

Adds a per-tick cover-backfill pass to the crawler daemon so mangas whose
cover download failed on first attempt get retried — the metadata pass's
early-stop optimisation otherwise prevents the walk from revisiting them.
Adds admin-only POST /admin/mangas/:id/resync and POST /admin/chapters/:id/resync
that refetch metadata + cover (or chapter content with force_refetch) from the
crawler source synchronously and return the refreshed row. Surfaced in the
UI as "Force resync" buttons on the manga detail and reader pages,
admin-only via session.user.is_admin.

Addresses the security-audit findings on top of the admin feature stack:
M1: /admin/mangas/:id/chapters now paginates (default limit 200, max 500).
A long-runner with thousands of chapters would otherwise produce a multi-MB
response with that many scalar subqueries per row — admin-only but a real
stall risk on one expand-click. Adds explicit pagination tests for the cap
and offset; frontend renders a "Showing first N of M" hint when the cap
clips the result.
L1: repo::user::set_is_admin renamed to set_is_admin_unchecked with a
doc-comment pointing at admin_safe_set_is_admin for production use. The
short name was a footgun — a future contributor reaching for it would
silently bypass self-protection, the last-admin invariant, and the audit
log. Used only by integration-test setup; production code goes through
the admin_safe_* paths.
CSRF posture: build_session_cookie carries a comment that the
SameSite=Lax default is the project's CSRF defense for state-changing
mutations and breaks the instant anyone adds a side-effecting GET under
/admin/*. Spells out what to do then (Strict + explicit token check).
Test counts: 43 backend admin tests + 12 vitest admin tests all green;
svelte-check 0/0 across 446 files.
Adds an `is_admin` flag on users plus the substrate every later PR in the
admin feature builds on:
- migration 0018 adds the column with default false
- `repo::user::bootstrap_admin` creates or promotes the user named by
`ADMIN_USERNAME` at startup, hashing `ADMIN_PASSWORD` only when the row
is new — never overwriting an existing hash, so an operator can rotate
the admin password via the UI without env-var conflict
- `CurrentSessionUser` extractor accepts only the session cookie;
`RequireAdmin` composes over it and additionally requires
`user.is_admin`. Bearer tokens are intentionally excluded so an
admin's bot token never inherits admin authority (privilege-escalation
surface that bites every "API keys reuse user perms" auth design)
- demotion is instant: `RequireAdmin` re-reads the user row each request
`/api/v1/auth/me` now exposes `is_admin`; no other response embeds
`User`, so no privacy fanout to audit.
