What it 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.
