Turning AI on later "just works" — your existing data is +never touched. + +Three deployment modes: + +**A. Development / auto-create (default `use_alembic=False`)** + +Nothing to do. `Admin.setup()` runs `create_all(checkfirst=True)` on every +startup, so flipping `ai_enabled=True` (optionally with an `AIConfig`) creates +the four missing `admin_ai_*` tables at the next boot. The AI schemas declare +`relations=[]` and no foreign keys (the "log pattern" — `user_id` / +`conversation_id` are plain indexed columns), so there are no FKs to worry +about, no data backfill, and no table-ordering issues. + +**B. Alembic (`use_alembic=True`)** + +`migrations/models.py` and `get_admin_metadata()` are deliberately **never +filtered** by `ai_enabled` — they always materialize the AI schemas, and +`fak init-alembic` generates an `env.py` whose `target_metadata` is +`AdminBase.metadata`. Therefore: + +- Projects that ran `fak init-alembic --auto-migrate` at the start already + have `op.create_table('admin_ai_*')` in their first revision, so the tables + exist and flipping the flag needs **no migration at all**. +- Projects whose database lacks the tables (e.g. an older database used with + `--baseline`) get them from the next + `alembic revision --autogenerate && alembic upgrade head`.
