//! Storage-format rotation as a recoverable-run tenant (K3 of
//! `docs/plan/storage-key-rotation.md`).
//!
//! Iterates `storage.blobs` for a target entry, decides per blob
//! whether the on-disk format matches what the entry's head pair
//! would write, and rewrites in place when it doesn't. Covers four
//! transitions with a single equality check:
//!
//! * Legacy blob (no `OXCPT` magic) → rewrite as v1 with the head
//! pair's format.
//! * v1 encrypted, decrypted under a pair-index other than head →
//! rewrite (key rotation).
//! * v1 plaintext with head=`aes:K` → rewrite (encrypt-in-place).
//! * v1 encrypted with head=`none:` → rewrite (decrypt-in-place).
//!
//! ### No readonly, no cutover
//!
//! `storage_rotate` is per-blob idempotent — repeat rewrites are
//! byte-safe (content-addressability holds; the wrapper always
//! produces the head format). Concurrent user writes coexist: they
//! land as head-format themselves, so when the walk reaches that
//! hash the classifier reports "already at head format" and the
//! decision tree collapses to `skip`. No app-wide read-only gate is
//! ever engaged — a critical improvement over `storage_migration`,
//! whose target-different-from-source cutover forces one.
//!
//! ### Restart survival
//!
//! Cursor + per-blob failure findings are persisted after every
//! batch. On restart, boot flips any abandoned `Running` row to
//! `Paused`; an admin trigger resumes from the checkpointed cursor.
//! The last checkpoint window (~100 blobs) re-processes; each of
//! those blobs is now head-format from the previous run's rewrite,
//! so the walk short-circuits without re-writing. Effectively free.
//!
//! ### Design notes
//!
//! * **Cursor** — UTF-8 hex of the last-processed blob hash (64
//! chars). Same encoding as `storage_migration` and
//! `blobs_consistency`.
//! * **Target lookup** — the entry NAME is stashed in `params` at
//! Fresh-open time and re-read on Resume. The wrapper for that
//! entry is rebuilt at the top of every run via
//! `build_entry_backend_typed`; mid-run config changes are
//! ignored until the next run (mirrors `storage_migration`).
//! * **Per-blob failures don't fail the run** — each failure records
//! a `rotation_failed` finding (severity `data_loss` — the bytes
//! didn't get rewritten) and the walk continues. A run that
//! completes with zero findings is proof every blob is at head
//! format.
//! * **`?deep=true` is unused** — rotation has no slow variant.
//! Parameter accepted for uniformity with other tenants; ignored.
