Postgres -> SQLite hard cutover: the database moves into the media directory. The database now lives at <media>/config/wrolpi.db so a library (files, configs, AND database) travels with the drive between WROLPi systems. Core: - wrolpi/db.py: lazy SQLite engine factory (WAL, busy_timeout=30s, foreign_keys=ON); get_db_curs yields a plain sqlite3.Cursor; native sqlite3 paramstyle everywhere (no compatibility shims); global sqlite3 adapters keep raw-SQL datetime formats identical to the ORM's. - wrolpi/fts.py: FTS5 external-content search replacing tsvector/GIN. Injection-proof websearch->FTS5 translator, bm25(10,4,2,1) reproducing A/B/C/D weighting, fast(abc)/deep column filtering, snippet headlines. Stemming contract pinned by dedicated tests (watch/watches/watched/ watching are interchangeable). - wrolpi/schema_ddl.py: SQLite triggers shared verbatim by the alembic baseline and test DBs; fixes the channel video_count DELETE/UPDATE bugs and a latent total_size bug (it used the video id as channel id). - wrolpi/db_bootstrap.py: startup auto-create/migrate; refuses databases written by a newer WROLPi (db_version_mismatch); SQLite 3.40 floor; network-filesystem refusal; never creates/migrates/trusts a database beneath an unmounted production media directory (shadow-DB guard). - Alembic: 85 Postgres-era migrations squashed into one baseline; revision ids are dates (2026_07_10_1350) so filenames self-sort and alembic_version says when a schema was created; render_as_batch=True. - All raw Postgres SQL rewritten (ANY->json_each IN, array_agg @> -> HAVING COUNT(DISTINCT), unnest->executemany/UPDATE..FROM, generate_series histograms->strftime GROUP BY, DISTINCT ON-> row_number(), writable CTEs->two statements, jsonb_->json_, explicit NULLS FIRST/LAST, LIMIT-before-OFFSET). Simple statements converted to SQLAlchemy instead (flag upsert, download retry/summary/tag checks, channel-by-tag estimate, Directory delete). - Config imports count skipped entries; background dumps are blocked after a lossy import so partial imports can never overwrite YAML configs (they are the sole source of truth for rebuilds now). - Search tolerates explicit JSON nulls for limit/offset (Postgres treated OFFSET NULL as 0; SQLite errors). - file_group.id/doc_section.id render as INTEGER PRIMARY KEY on SQLite (BIGINT is not a rowid alias; FTS5 content_rowid requires it). Ops teardown: docker-compose db service, CI postgres sidecars, initialize_api_db.sh, controller postgresql service, psycopg2-binary all removed. upgrade.sh stops/disables postgresql (data is NOT deleted; `systemctl enable --now postgresql` restores it); systemd units no longer Want postgresql.service. Existing-user upgrade: first boot creates+migrates the DB, configs import (tags recreate their FileGroups from disk), a refresh rebuilds the library index. QA'd on the 10.0.0.8 RPi: rebuild matched the Postgres baseline exactly; survived an uncontrolled hard reboot with clean integrity checks. Accepted behavior changes: FTS5 has no stopwords; bm25 length normalization shifts some rank orders; fast-path d_headline is un-highlighted; all-negative queries match nothing. Deferred: Debian/trixie package lists (incl. sqlite3 CLI), Cypress re-baseline, VACUUM INTO snapshots, exFAT/NTFS warning, auto-kicked rebuild refresh with progress UX.
