fix(ingester): close #5 within-chunk live posts + #8 video transient retry
Review of the #1–#9 ingester roadmap found two real-but-small gaps; this closes both. #5 (live posts progress) shipped at per-chunk granularity — _apply_backfill_ lifecycle accumulated DownloadResult.posts_processed AFTER each chunk, so the badge didn't move during a chunk (up to ~14.5 min) and over-counted the re-walked resume page. The plan called for within-chunk live updates. Move ownership of _backfill_posts into the ingester: ingest_core writes a monotonic absolute (posts_base + net-new) via _checkpoint_posts at each page boundary and once at the end, EXCLUDING the resumed page so it no longer inflates across chunks. download_service seeds posts_base from prior chunks and stops touching the key (the lifecycle now carries the ingester's committed value forward). #8 (per-media transient/permanent retry) covered only the plain-GET path (_fetch_to_file); the Mux/video path returned None on any yt-dlp failure with no retry. Give _run_ytdlp the same split: TimeoutExpired/OSError are transient (back off + retry up to _MAX_MEDIA_RETRIES), a non-zero exit (CalledProcessError) is permanent (yt-dlp already did its own network retries) → fail fast to the per-item/dead-letter path. Tests: live-posts absolute + resume-page exclusion + tick-doesn't-persist (test_patreon_ingester); lifecycle-leaves-posts-to-ingester rewrite (test_download_service); video transient-retry + permanent-fail-fast (test_patreon_downloader).

refactor(ingest): extract platform-agnostic Ingester core — roadmap #9 (plan #706)
Factor the native-ingest orchestration out of PatreonIngester into a reusable ingest_core.Ingester base, parametrized by client/downloader/ledger-models/ constraints/key/platform/error_base. PatreonIngester becomes a thin adapter: it resolves the Patreon client/downloader, wires the seen/dead-letter models + UNIQUE-constraint names + _ledger_key into super().__init__, and overrides _failure_result with the Patreon exception taxonomy. Behavior-preserving — no table rename, no migration; the public surface (PatreonIngester, _ledger_key, DEAD_LETTER_THRESHOLD, verify_patreon_credential) is unchanged. This is the strategic seam: SubscribeStar/etc. now migrate by writing a ~40-line adapter, not by re-implementing the tick/backfill/recovery walk, tiered skip, checkpoint, and dead-letter logic. run() moved to ingest_core, so the budget test's monotonic patch repoints to ingest_core.time.

feat(patreon): dead-letter ledger for permanently-failing media — #705 step 2 (#7)
A media that fails every walk (404'd CDN, deleted post, geo-blocked Mux, persistently-corrupt bytes) used to re-error forever and re-burn chunks. New `patreon_failed_media` table (alembic 0038, chains 0037) records per-media attempts; once attempts reach DEAD_LETTER_THRESHOLD (3) the ingester skips it on routine tick/backfill walks (tier-1.5, folded into the seen/skip predicate). Recovery BYPASSES it (the operator's "try everything again" re-attempts dead media). A clean download clears the row (recovered); errors/quarantines upsert-increment it. Surfaced as run_stats.dead_lettered_count. - New PatreonFailedMedia model + migration; ingester _dead_keys / _record_failures (on_conflict increment) / _clear_failures. - skip = seen | dead (empty in recovery); failures recorded post-fetch on short sessions (same pattern as the seen-ledger). Tests: a media erroring 3× is dead-lettered + skipped (no download attempt); recovery re-attempts a dead media and clears it on success; a clean download clears a sub-threshold failure.

feat(patreon): incremental cursor checkpoint mid-walk — #705 step 1 (#6)
A worker SIGKILL (hard-time-limit backstop) mid-chunk lost the whole
chunk's walk — the cursor was only persisted at chunk boundaries by phase
3, so the next tick re-walked from the chunk start. Now the ingester
checkpoints _backfill_cursor to the DB at each page boundary (backfill/
recovery only) via an ATOMIC single-key UPDATE (config_overrides::jsonb →
jsonb_set('{_backfill_cursor}') → ::json), so it never clobbers operator
config or other backfill keys. On a crash the last mid-walk cursor
survives → the next chunk resumes near the crash, not the chunk start.
phase 3 still writes the final cursor (same value); this is the safety net.
Tests: a backfill walk leaves the last page's cursor in the DB (written by
the ingester, before any phase 3); a tick never checkpoints.

test(patreon): fix #704 — quarantine status + budget-cut cursor assertions
Two test breaks from the structured-results change: - An existing downloader test pinned a corrupt file to status "error"; it's now the distinct "quarantined" status (the new behavior). Updated it + removed the duplicate I'd added. - The budget-cut ingester test asserted the checkpoint cursor was the last FULLY-processed page (CUR1); it's actually the page we were cut on (CUR2, entered + cursor emitted before the budget check), matching the prior parse_last_cursor(last) semantics. Corrected the assertion. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

feat(patreon): structured ingester results + quarantine surfacing — #704 step 1
The native ingester faked gallery-dl stdout (`Cursor:` lines, summary) and phase 3 regex-scraped it back — so Patreon run-stats were mostly zero and quarantine stats blank. We own the ingester, so it now RETURNS structured data and phase 3 reads it directly. - DownloadResult gains run_stats/cursor/posts_processed (None/0 on the gallery-dl path, which keeps the text route). - Ingester builds real run_stats from per-media outcome counts, sets the checkpoint cursor structurally (no fake `Cursor:` stdout), and counts posts processed. download_service phase 3 uses dl_result.run_stats when present; the backfill lifecycle + TIMEOUT→PARTIAL block checkpoint dl_result.cursor instead of parse_last_cursor(stdout). - #4 quarantine: PatreonDownloader reports a distinct "quarantined" MediaOutcome (with the _quarantine dest); the ingester surfaces a real files_quarantined + quarantined_paths + run_stats.quarantined_count (was hardcoded 0). Quarantined media isn't written or marked seen. - Cleanup: parse_last_cursor + _CURSOR_RE (and the now-unused `import re`) removed from gallery_dl — the structured cursor replaced the scrape. Tests: ingester result carries real run_stats/cursor/posts_processed + quarantine counts; downloader quarantines an invalid file as "quarantined"; backfill cursor tests pass cursor= structurally; dropped the parse_last_cursor tests.

feat(downloads): native Patreon verify + uniform backend dispatch (plan #697)
The credential Verify button still ran gallery-dl --simulate for Patreon after the cutover — testing the wrong path (and prone to the vanity "Failed to extract campaign ID" the native resolver fixes). Wire it to the native ingester, behind a DRY dispatch so callers never branch on platform. - services/download_backends.py (new): the ONE place that knows which platforms are native vs gallery-dl. `uses_native_ingester(platform)` is the shared predicate; `verify_source_credential(...)` is the uniform probe (same (ok|None, message) contract for both backends). As a platform migrates, it moves into NATIVE_INGESTER_PLATFORMS here and BOTH download routing and verify switch together. - PatreonClient.verify_auth(campaign_id): one authenticated /api/posts fetch → True (valid) / False (401/403/HTML-login) / None (drift or network — inconclusive, not a credential verdict). - patreon_ingester.verify_patreon_credential(): resolve campaign id, then verify_auth — the verify counterpart to the download path. - patreon_resolver.resolve_campaign_id_for_source(): extracted the override / id:-URL / vanity resolution into ONE helper now shared by the download ingester and verify (download_service no longer carries its own copy + regex; −`import re`). - download_service: routes on uses_native_ingester() instead of inline `== "patreon"` (3 sites); uses the shared resolver. - api/credentials: calls verify_source_credential — no platform branch. Tests: verify_auth mapping, resolve_campaign_id_for_source (override/id:/ vanity/none), the dispatch predicate, verify_patreon_credential glue, credentials endpoint proves Patreon uses the native path (gallery-dl verify asserted not-called); repointed the gallery-dl verify test to subscribestar.

feat(patreon): drift detection + error categorization — build step 4 (plan #697)
Typed, loud failure mapping for the native Patreon ingester so a changed
API shape or expired auth never silently zero-downloads as "success".
- New ErrorType.API_DRIFT (free varchar error_type col → no migration):
distinct from auth so the operator knows the fix is updating the
ingester, not rotating cookies.
- patreon_client: PatreonAPIError carries status_code; new PatreonAuthError
for 401/403 + HTML-login/non-JSON bodies (reclassified from drift —
expired-session is auth, actionable as "rotate cookies").
- patreon_ingester._failure_result maps: PatreonAuthError→AUTH_ERROR,
PatreonDriftError→API_DRIFT ("Patreon API changed — ingester needs
update"), HTTP 429→RATE_LIMITED, 404→NOT_FOUND, other HTTP→HTTP_ERROR,
transport→NETWORK_ERROR. (429 thus drives the platform cooldown.)
- FailingSourcesCard: api_drift chip (red) + hint.
Contract test (new test_patreon_contract.py): the recorded /api/posts
fixture must parse end-to-end (no drift, 5 media across 4 posts) AND the
request params must still carry every field the parser depends on
(file_name, image_urls/download_url, images/attachments_media/media
includes, content/post_file/image post fields) — a trim of either trips a
red build. Plus client HTTP-status classification tests and ingester
error-type mapping tests.

feat(patreon): phase-2 ingester integration — build step 3 (plan #697)
Branch download_service phase 2 by platform: Patreon now routes to the
native PatreonIngester (zero per-file HEADs, native cursor/resume, loud
drift detection) instead of gallery-dl; the other 5 platforms are
unchanged. The ingester returns a DownloadResult-shaped object so phase 1
(DB setup) and phase 3 (import → pHash → thumbs → ML) are untouched.
Three modes wired from config_overrides state:
- tick: skip seen (tier-1 ledger + tier-2 disk), early-out after N
contiguous already-have-it items.
- backfill: full-history time-boxed chunk, cursor checkpoint via
gallery-dl-style "Cursor: <token>" lines in stdout (reuses the #693
lifecycle + parse_last_cursor verbatim).
- recovery: backfill that BYPASSES the tier-1 seen-ledger so
dropped-and-deleted near-dups get re-fetched and re-evaluated under
the current pHash threshold. Rides the #693 state machine via a
_backfill_bypass_seen flag, cleared on completion / stop.
The seen-ledger uses short-lived sync sessions (injected sessionmaker),
never held across the walk (avoids the connection-reaping trap). Campaign
id resolves from override, an id: URL, or a vanity lookup; unresolvable =
loud NOT_FOUND, never a silent empty success.
Tests: new test_patreon_ingester.py (modes, ledger skip/idempotency,
budget→PARTIAL, recovery bypass, tier-2 disk, drift). The patreon-oriented
download_service tests now drive the ingester branch via a stub; the
gallery-dl campaign-retry test is replaced by resolution/caching coverage.
