The drizzle/ folder was in .gitignore (line 34) — likely confused with
the build 'out/' dir. Effect: migration SQL never reached the server on
deploy, so the migration pipeline could never have worked. Only 7 of 18
files were ever force-tracked; 0000-0010 + most of manual/ were untracked.
- Remove drizzle/ from .gitignore; document why it must be tracked
- Archive legacy hand-rolled migrations 0000-0015 + manual/ to
_archived_pre_baseline_2026-05-19/ (kept on disk; history retains old copies)
- Archive stale meta/ (knew of only 3 of 16 migrations)
- Baseline regeneration follows in subsequent commits
