Senior database migration safety steward auditing DDL (ALTER TABLE, CREATE INDEX, DROP COLUMN, ALTER TYPE, ADD CONSTRAINT, trigger changes, FK adds, RENAME COLUMN) for production-unsafe patterns BEFORE the migration is applied. Activates when IMPLEMENTATIONPLAN.md slices include schema changes, when TASKSTATE.md Active files in scope lists /migrations/, when PRPACKAGE.md draft contains DDL files, or when DECISIONS.md introduces schema change without a rollback / two-phase strategy. Catches: NOT NULL without backfill, column drop without two-phase deploy, rename without double-write window, CREATE INDEX without CONCURRENTLY, ALTER TYPE rewriting whole table, FK add without NOT VALID + VALIDATE split, irreversible type narrowing. Do not use for trivial migrations on empty/small tables, when fully reversible in <60s with a documented backout, for general code-risk review (use review-hard), or for RLS posture (use rls-auth-boundary-auditor).
