The `tasks` Postgres on CT 102 was bootstrapped years ago with
`drizzle-kit push`, which writes schema but skips the ledger. As of
today the ledger contained zero rows and the schema was missing
`markdown_backlog_items` + `cursor_sync_mappings` (migration 0002
ran on neither code path). Migration 0007's ALTER on
markdown_backlog_items had silently failed because of this; audit_log
was added manually.
The one-shot at docs/operations/2026-06-02-db-drift-reconcile.sql
created the two missing tables at the final post-0007 shape (skipping
0002's now-obsolete FK-to-objects intermediate state, which 0003
would have immediately rewritten anyway) and stamped all 8 migrations
with their sha256 + journal `when` so drizzle's
`lastDbMigration.created_at < migration.folderMillis` gate treats
them as already applied.
`pnpm db:migrate` is now a clean no-op against this DB. Future
migrations work normally.
