Use when adding, altering, or dropping anything in the MySQL schema — any new file in compose/local/database/migrations/, or when a new enum/status value is needed. Covers Flyway timestamp naming, additive-only rules, and the risk:migration label.

date -u +%Y%m%d%H%M%S → V<stamp>__short_description.sql in compose/local/database/migrations/. Never a bare integer; never rename/renumber a merged migration (Flyway tracks version + checksum).outOfOrder=true, so PRs apply in arbitrary order — a migration must NOT depend on a later-timestamped one having already run.logs.action_type, posts.status, …): adding a value = ALTER TABLE … MODIFY COLUMN restating every existing value plus the new one. Then use the enum in code via PostStatus / PostType / LogActionType from db.py — never raw strings.src/cqc_lem/utilities/db.py — no raw SQL anywhere else. Add the accessor there.risk:migration — the agent still builds, but a human signs off before merge (park with needs-human + a Decision Comment).Scheduling/time columns: store naive UTC via to_naive_utc() — see docs/timezone-contract.md.
