oc-migration-ops

Migration and refactor operator for live systems: database migrations (D1 → Postgres, schema overhauls), framework upgrades (Hono v3→v4, React 18→19), auth provider swaps, monorepo restructures, and platform moves (Workers → Vercel). Produces incremental plans with rollback points at every step, executes with verification gates, and validates the end state matches the target spec. ALWAYS trigger on /oc-migrate, /oc-migration, /oc-upgrade, /oc-refactor, /oc-swap, /oc-move-to, /oc-platform-move. Also trigger on "migrate from X to Y", "upgrade to", "swap auth provider", "move database", "restructure the monorepo", "refactor to use", "breaking changes", "deprecation", "end of life". Also covers opchain ecosystem upgrades: "update all skills", "checkpoint protocol upgrade", "bulk update SKILL.md". Trigger when transforming an existing system from one state to another — not greenfield building (oc-app-architect) or documenting what exists (oc-reverse-spec).
