Step 0 of the roadmap: everything from the moderation queue onward adds
columns, and init_db could only ever run CREATE TABLE IF NOT EXISTS, so
it could not alter a live deployment.
- Track schema state in PRAGMA user_version and run ordered migrations.
Fresh installs create the v1 table and migrate forward, so the upgrade
path runs on every new deployment rather than only on old ones.
- Rebuild media with UNIQUE(owner_id, file_unique_id). The old global
unique constraint stopped two users from each saving the same file,
which blocks public mode.
- Replace INSERT OR REPLACE with an upsert. Replacing deleted and
reinserted the row, giving it a new id and silently invalidating any
id the user had noted from /list.
- Give search_media an optional owner_id scope, defaulting to the
current shared-library behaviour.
