This reverts 2529b51. Not a retreat — a reordering, on the operator's
call, and the better sequence.
The squash's acceptance test (run 4971) found ~130 places where the ORM
models do not describe the deployed schema (#3275), including a
unique=True the database never had and two UNIQUE indexes that exist
only in migrations. Collapsing now would have baked all of that into the
one file a public installer starts from.
So: fix the drift first as ordinary migrations on the intact chain, let
the operator deploy so their database moves to the corrected head, and
only then collapse. The baseline is then generated from reconciled
models and reproduces a schema worth reproducing.
Nothing is lost by reverting. The baseline was never deployed, and
regenerating it after the fixes is strictly better than patching this
copy — it will come out of autogenerate correct rather than needing the
same hand-finishing twice.

"""patreon_seen_media: per-source ledger of already-ingested Patreon media

Revision ID: 0037

Create Date: 2026-06-05

|
|
Native Patreon ingester (build step 2a). Replaces gallery-dl's
|
|
archive.sqlite3 with our own queryable table. The downloader upserts one
|
|
row per (source, media) so routine walks skip media we've already
|
|
processed; a future "recovery" mode bypasses the ledger to re-walk.
|
|
|
|
`filehash` is a 32-hex Patreon CDN MD5, OR a video sentinel of the form
|
|
``video:<post_id>:<media_id>`` — hence String(128). The unique
|
|
constraint on (source_id, filehash) is the dedup upsert key.
