Browse scrapers backfilling old catalogs stamp the tube's import/post date as
release_date, so old content (e.g. 83 MissaX classics via perverzija, ~3600/3 days
across eporner/youporn/etc.) fake-ranked as newest and flooded the favorites "+N".
NULLing the dates was a non-starter — the stub filter would hide 251k performer-less
scenes. Instead: a Scene.backfill flag marks bulk catalog imports; they stay visible but
never count as "new".
- scenes.backfill column (+ index, migration 0026); resolve_scene/_process_scene thread it.
- deep_crawl tags scenes from pages beyond the "latest" threshold (>2) as backfill;
latest pages + TPDB/StashDB delta stay genuine. Cursor reset re-sweeps page 1 so real
new content is always caught fresh.
- favorites +N (performers + studios) excludes backfill within the top-200 window.
- SceneOut exposes `backfill`; mobile NEW badge + NEW-first re-sort skip it (badge==count).
- Retroactive: tagged 439k existing scenes in bulk (>10 non-canonical / studio / day)
clusters. Device check: favorite-studios +N 11626 (naive) -> 236.
