Hand mutant T4 (lead >= 0x90) survived; the empty-array case now carries a newer stamp after it.

The Unity list no longer calls MarkFlushSucceeded removed and places HeaderFor and the CacheBackingStore members where apicompat finds them. cultnet-rs gains a CHANGELOG. The store-composition contract moves DecodeDocument to the codec and states that a call's registry serves that call only. Docs only.

The stamp functions (Rust refuse_unread_format, TS refuseUnreadFormat) are the single owner of the stamp rule, accept v1 and v3, and are called only from the one reader every whole-store write runs under the lock. The fix's header peek (TS refuseUnreadStoreBytes, peekHeader) is deleted. Its tests that v3 is refused and that a stampless file is healed are dropped; the reversal is a Breaking line in the Rust and TS CHANGELOGs. The 0xff-after-stamp test now runs over v1 and v3.

Owns finding c2a-public-breaks-not-in-changelog. Leaf changelogs gain v3 read and write and element ids carried; cultcache-rs gets its first changelog (the whole-store writer fix is not on main, so no 0.3.1 section).

refuseUnreadFormat is shared by isV1Snapshot and the writer's header peek; message text unchanged. Builds.

Both new tests fail at this commit; it builds. Vector copied byte-identical from C2a (blob 9fc9b64f).

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.

Fixes variants:finding:cut-ts-store-write.s2.changelog-csharp-any-write-overclaim:
a C# conditional commit on a clean store lands onto the current file; other
C# writes can still overwrite concurrent TypeScript records.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
push and delete no longer lose records across concurrent TypeScript and Rust writers. A full
pushAll and any C# write still replace the whole store.

The default StoreFileOps were never observed. One test now wraps fs/promises.open and each handle's
sync and close, and records the store's bytes at every call: the staged file is synced and closed
while the store still holds its old bytes, and on Unix the directory is synced and closed after the
store changed. A second test puts a directory at <store>.lock and requires the lock to fail within
3 s with the lock path named, under the default 30 s wait bound.

A share-none open (what the C# lock and readers need) must succeed after the replace
and after a waiter gave up.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Both directions: a TypeScript write waits on a C# or Rust holder; a C# or Rust writer
waits on a TypeScript holder; the lock wait bound names the lock path.

#enqueue takes withStoreWriteLock; the legacy heal moves out of pullAll's read into a
queued, locked operation that re-reads; push and delete read through #readDisk so they
never enqueue from inside the locked queue (a self-deadlock). Builds.

commitStoreFile stages a unique temp, fsyncs it, replaces the store and fsyncs the
directory on Unix. Windows replaces POSIX-semantics first with a write-through
MoveFileExW fallback and a 25x20 ms retry on 5/32/33 (koffi, loaded lazily). The
cross-process lock functions land in the same file but are wired in a later commit.
package-lock.json also carries pre-existing version drift from regeneration.
Builds.

One browser-safe module owns the manifest and chunk-ref shapes, their MessagePack form (positional ten-array, metadata as
ordered entries, duplicate keys and unsafe integers refused, payload depth through cultcache-ts's own checkPayloadDepth),
normalizeHash/parseSha256Hex, both record-key grammars (StableToken per UTF-16 unit), WebCrypto sha256Hex and packContent.
cultcache-ts/document re-exports checkPayloadDepth. scripts/write-cultmesh-content-vectors.mjs writes the TypeScript
manifest vectors for the C# reference to judge.
Builds. Co-Authored-By below.

Main's two payload-depth tests staged a record with no catalog entry and
asserted that the inspector and the single-file store infer its schema from
the payload's first element. C2a refuses a record whose schema id the catalog
lacks (merge-r1-precedence, exact binding), so the guess door is gone. The
inspector test keeps the bound check with a catalog entry that names the
schema; the store inference test goes with the door.

C2a's writer, catalog and soft-push tests handed raw Uint8Array payloads to
the store. Main made the envelope payload an opaque DocumentPayload, so they
wrap with documentPayloadFromBytes and read back with documentPayloadBytes.

Sixteen conflicted files resolved by the spec's rule: main owns payload
ownership, bounds and the Clock seam; C2a owns persistence semantics and exact
binding. MintStoredAt is internal static (previous, now); the cache and the
store pass their cache's Clock. Package versions are main's. The cultmesh-ts
payload-parse acceptance and its test are deleted under retire-schema-alias;
peer snapshot reads take the schema's own id, else an id the definition lists
as compatible. The held firstRecordAtKey fallback is removed: main's handles
take definitions only, so nothing could reach it.

The wide-count test announced map32 as 32770 pairs, which fits in 16 bits, so a
count read as its low 16 bits survived. map32 now announces 65537 pairs and
array32 65540 children; both low halves close the container early.
Builds: yes.

Findings custom-formatter-bytes-walked (ruling depth-walk-covers-library-msgpack: the owner skips the walk when the definition carries a formatter; the grey 0x91 image round-trips, plain and codec stay bounded; README says so) and wide-length-unpinned (bin32/str32/ext32 of 65539 bytes and array32/map32 of more than 65535 children before a chain at and past the limit). The same tests pin the inspector refusing to recover a stamp from a past-limit payload. Not yet built.

Finding inspector-recover-unwalked: one decodeBoundedPayload (walk, then decode) serves both the stamp recovery and the preview, so a payload past the limit is never decoded by either.

Kills the survivors of the first mutation sweep (fixext2 skip, 0xc1, the fixarray/fixmap/fixstr upper bounds, map16 and map32 child counts).

The C# cases and the TS assertions are here; the vector file is written from the reference in the next commit, so the
slot-nil tests of both runtimes fail at this commit.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
checkPayloadDepth is an iterative header walk run by decodeDocumentPayload before the formatter and by
encodeDocumentPayload on the formatter's bytes; the two plain-decode inspection doors call it first. The plain
formatter's encoder depth is set above the limit so the walk decides. Tests: the C# bounds vectors, the walk's
header and scalar rules, the owner, the inspector, the legacy version inference, and the mesh network doors;
test:pack:ts denies decoder-shaped exports by enumerating the packed entries.
Builds and passes untested at this commit (verification runs on Yggdrasil next).
