First live run (cheunart) tripped the drift guard: "no posts and no recognizable
feed container". The browser-saved page was normal (6 posts + posts_container-list),
so the parser was fine — our live HTTP fetch got a different response. Cause: the
client set X-Requested-With: XMLHttpRequest (+ a JSON Accept) session-wide, so the
initial creator-page GET was sent as an XHR. SubscribeStar (Rails) content-
negotiates an XHR full-page request to a non-HTML body → no container → drift.
Fix: the session now uses browser-like navigation headers (Accept: html, NO
X-Requested-With); the XHR header + JSON Accept are applied PER-REQUEST only on
the "load more" endpoint (which is a genuine XHR). Drift message now reports the
response length + a JSON hint so a recurrence is self-explaining. Regression test
pins the header split (navigation initial GET, XHR load-more).

DRY pass commit 1 (process #594). Consolidate the helpers + download plumbing
the Patreon and SubscribeStar adapters had duplicated (SubscribeStar was
importing patreon privates — wrong owner). New backend/app/services/
native_ingest_common.py is the neutral home for:
- make_session (was _load_session ×2), retry_after_seconds + 429 constants,
sanitize_segment, basename_from_url, post_dir_name, MediaOutcome /
PostRecordOutcome.
- BaseNativeDownloader: the shared streaming GET (transient-retry + Range-resume)
and validation/quarantine. Patreon + SubscribeStar downloaders now subclass it;
each keeps only what differs (Patreon's Mux/yt-dlp video branch + detail-fetch
enrichment; SubscribeStar nothing extra). Behavior preserved exactly; the
divergence-bug risk (a fix to one _fetch_to_file not reaching the other) is gone.
- Folds in #899 L2: a quarantine now log.warning's path+reason (was counted only).
post_dir_name merges both date handlers (accepts trailing-Z and pre-parsed ISO).
Tests repointed to the single source at every consumer (rule 93 / §8b parity):
patreon_client/downloader, subscribestar_native. Exception-trio consolidation +
base _failure_result (2/3) and the remaining ingest_core logging (3/3) follow.

Phase-1 steps 2-4 of moving SubscribeStar off gallery-dl onto the native core
ingester. SubscribeStar has no JSON:API, so the client scrapes HTML; the
platform-agnostic core (ingest_core) is unchanged.
- subscribestar_client.py: HTML-scrape read path. iter_posts pages via the
creator page → infinite_scroll-next_page href → JSON {html} fragments
(campaign_id = creator URL; no resolver). extract_media reads the per-post
data-gallery JSON manifest (id/original_filename/type/url). post_record_key,
post_meta, and post_is_gated (best-effort locked-teaser marker, pending a live
locked sample). Loud auth/drift taxonomy (SubscribeStar{API,Auth,Drift}Error).
Parser validated against the real Step-0 fixtures.
- subscribestar_downloader.py: mirrors PatreonDownloader minus the Mux/yt-dlp
branch (SubscribeStar serves files directly via /post_uploads). gallery-dl
on-disk layout so existing downloads dedup on disk at cutover. Post-first:
_post.json owns the body/links; per-media sidecar carries image identity only.
- subscribestar_ingester.py: thin adapter wiring client/downloader/the
SubscribeStar ledgers into the core; ledger_key = filehash else
post_id:media_id; SubscribeStar failure mapping. verify_subscribestar_credential.
- tests: client parsing/pagination/media/gating/record-key/dates, downloader
layout/sidecar/post-record/skip-seen, ingester ledger_key + failure mapping.
Not yet wired into dispatch (Step 5) — these modules are inert until then.
