A staged write mints a later storedAt, so the 'rewrite kept storedAt' premise is gone; the pin is that a record rewritten under another schema fails Expect. The variant refusal names the renamed base through ChangedKeys, as C2a's typed exception carries it.

Directory store now sets StoredSchemaId with StoredVersion after a page write (found by main's OwnPushOfALoadedDriftedEntryKeepsExpectHolding). RecordRewrittenUnderAnotherSchema stages the record, since a flush writes only the write set. Variant conflict test expects CultWriteConflictException.

Stamp rule runs on slot 0 before the body is scanned (JudgeStamp). DescribeHeader names a v<N> header that carries a suffix. Rust store_header walks on the grown stack. Drift tests declare Wide's id compatible (ownership by declaration). Mesh write-guard tests expect the typed refusals.

Identity: C2a's StoredSchemaId/StoredVersion owns; main's PersistedSchemaId, PersistedIdentity and both MarkWritten are deleted. Stamp rule: ReadStore judges the stamp before the body. Flush over damage refuses (merge-r1-precedence). Mesh single-file writes route through SingleFileMessagePackBackingStore. TS: store-file.ts commits, C2a's header handling kept. Rust: C2a's readable_store_format in front of the grown decoder. Build not yet verified at this commit.

Single-file PushAll reads the format stamp under the lock and refuses cultcache.store.v<N> with N > 2;
the directory store throws NotSupportedException for N > 4 from the manifest parse every write already runs.
An unreadable stamp keeps today's behaviour.

C2a's StoredVersion owns the same identity and deletes both. No consumer outside CultLib uses them,
so they do not ship public in 2.0.0 and C2a's release is not a major.

The write replaced the file without reading it, so a 2.0 writer pointed at a store a newer
format stamped (or one holding other records) destroyed it.

A protected static mark let any subclass mark another store's or cache's
entry. The instance form throws ArgumentException unless the entry is the
one this store holds in its own Entries at that key. Both library stores
already mark only their own entries, so their calls are unchanged.

The directory store's write of a generation marks each page it wrote once the
manifest names it, so a Push+PushAll of a loaded drifted entry no longer leaves
its persisted schema id stale. The single-file store marks through the same
member, and a store outside GameCult.Caching now has a supported way to mark
its own rewrite. The getter's doc names how a store records a rewrite.

Red until stores mark through a protected base member: the directory store's
Push+PushAll leaves the entry's persisted schema id stale, and a store outside
GameCult.Caching has no way to mark.

The directory store's pull filter compares the persisted schema id too; without a same-storedAt rewrite on that store nothing pinned it.

The claim that every write mints a later storedAt is false for a whole-file write, which keeps storedAt and rewrites a drifted record under the writer's schema. State what the identity is and what a rewrite does to another cache's Expect.

The six reads that took Descriptor.SchemaId as a record's durable identity (ConditionsHold, Expect, the store-less commit, both pull filters, JudgeMerge) now read CultStoredDocument.PersistedSchemaId. The store sets it from the record it read, a stamped entry starts at its descriptor's id, and a completed whole-file write (single-file PushAll, whole-view CommitBatchCore) resets it under the hold. A variant and its resolved view share it. An unchanged record loaded under compatible drift now satisfies Expect and ExpectUnchanged.

Red at b549d731: an unchanged drifted record fails Expect on both stores, and another writer's normalising flush is not seen. Pins the cases of cultlib-gaps:cut_spec:cut-expect-persisted-schema.r1.
