What this skill does
Migration Map current readers, writers, data shape, compatibility window, and ownership before editing. Define forward path and rollback path. Preserve existing data; make destructive steps explicit and separately authorized. Keep mixed-version operation safe where rollout can overlap. Sequence expand, migrate, verify, then contract when applicable. Make retries idempotent and partial failure observable. Verify old and new paths at required transition stages. Stop after requested stage passes; do not perform later destructive contraction implicitly.
