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.

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.

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.

Fields takes an optional legacy name per field, matched on read only and mapped to the same index as the current name, so a legacy and a current name in one object are the same property and the duplicate rules decide (refused when AllowDuplicateProperties is false, last wins otherwise). Writing never emits a legacy name. MessagePack bytes are unchanged.

SPIRV-Cross renames members matching GLSL builtins, so the source names change. Resolver and JSON writer accessors follow the members; the wire (positional MessagePack, JSON keys) is untouched in this commit. The committed GLSL is stale until its regeneration commit, so CommittedGlslEqualsLowering fails here.

[MessagePackFormatter] refusals and the door's written-as-object branch.
Classify gains Leaf for attribute-formatted, [DataContract] and string-keyed

WrittenAsWalked required StandardResolver's formatter to equal one of the walk's own families, which refused every source-generated formatter. WrittenAgainstWalk asks one contrary resolver per walk kind and refuses only on a reference match. DcSeq is refused as a collection written as an object; FormattedRoles passes (registration owns the attribute).

EnumeratesObjects took ElementTypeOf first, which for a dictionary is the
KeyValuePair (a leaf), so a keyed Dictionary subclass never reached the path; the
map's value type is asked first. The unreachable null-standard guard in
WrittenAsWalked is removed. Tests pin the direction and wording of the refusal, the
attribute-formatter collection case and the unwrapped inner exception.

CultElementIds is the walk's model of a type; MessagePack's StandardResolver owns how
a type is written, and nothing checked that the two agree. ResolverClaim now asks,
for each id-path type, whether StandardResolver's formatter is the object or union
resolver's (a type read by key) or a collection resolver's (a collection), and refuses
the document at first encode or decode when it is not, naming the type. A keyed type
that enumerates objects goes on the path so a keyed List subclass is caught. A type
MessagePack cannot build a formatter for, and a resolver ahead that throws, are typed
refusals; the AllowPrivate catch is pinned (s4: keyed-enumerable-misclassified,
allowprivate-catch-unpinned).

It writes the [Key] layout plus non-public keyed members, and registration now refuses any of those that
reaches an object list, so no element id can be dropped. The comparison is made lazily, only after an
ahead resolver returned a non-standard formatter, and an exception from it reads as not equal.

The single-file store records, per pull, which plain records decoded holding a non-empty
element id and at what version. A write whose copied record is still at that version
marks the header (v3). The record is positive-only and version-gated, so nothing a load
records can unmark a store. The directory store passes false: only C# writes it.

Registration: a concrete element type of an object list that is not keyed, and
[MessagePackFormatter] on any type or member on the id path or on the id member, are
refused. The id path is a fixed point over the walk's edges. The codec refuses, once per
document type and on every encode and decode path, a resolver ahead of StandardResolver
that formats a type on that path. UnionArmGuardTests moves StubArm out of the list union.

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.

CacheBackingStore.JudgeChecks (default: the view; single-file and directory stores read under their lock) replaces Land's view-only loop over non-home stores. Foreign takes the version the store read; CultForeignRecord.StoredVersion is get-only and set by the ctor, and every assignment after Foreign is deleted. One commit carries both spec commits 1 and 2 (the edits share hunks); unverified until the final job.

Remove and Commit of an unheld key no longer read the store at the call: the key travels as CultCommitRequest.Checks (commit) or a staged check (flush),
and each writable store judges it in RefuseUndeclaredOnDisk with the keys it writes, never removing it. A batch that only checks writes no file.
CultForeignRecord.StoredVersion records the version a store read, and the one ConditionsHold takes the store's foreign records.
Folds spec commits 1 and 2 (their hunks share the same methods). The src projects build; tests/GameCult.Caching.Tests does not at this commit
(CultCommitRequest gained a parameter; the next commit updates the test).

CultPayloadDepth.Check walks MessagePack headers iteratively and refuses the first
container past CultMessagePackSecurity.MaximumPayloadDepth, read or skipped, called by
SerializeUntyped (on the bytes it produced) and DeserializeUntyped (before decoding).
UntrustedData's 500 is replaced by the same value as a backstop. CultUnionGuard refuses
[k, nil] arms. New vectors in tests/vectors/union-parity, with bounds-outcomes.msgpack
as their data; the gate now runs every Check-calling test body and fingerprints bytes

A removal of a key the cache does not hold writes nothing, so it never reached
the apply; it was checked against the foreign list of the last load, and a
foreign record that arrived since was reported removed. Each store now reads
its durable state for such a removal (RefuseRemovalOfUndeclared) and refuses
through the apply's own RefuseUndeclaredOnDisk, which reloads and lists the
record. The load-time check (RefuseRemovalOfForeign) is deleted: the durable
read refuses everything it refused, and it could not save that read. A store
kind that cannot read its durable state keeps the view check as its default.

Refuse reloads a refused key as a pull loads it, and now that includes the
store's foreign list: a record another writer moved to an id this cache cannot
read is listed in ForeignRecords after the refusal, so the next write of that
key is refused at staging instead of again at the flush. Both store kinds give
Refuse the durable record's foreign entry (ForeignAt); the variant refusal too.

ForeignOnDisk and the two RefuseForeign calls in PushAll and CommitBatchCore are
gone. ApplyWriteSet refuses first, over every key it writes or removes, by
Registry.Declares for a cache and by the catalog entry it writes for a cacheless
CultMesh write. Both refusals reload through one DurableAt; the directory store
reloads through LoadPage, the per-record body of LoadRecordPages.

Declares (registry) is the one answer to whether a cache may write, relabel
or remove a record stored under an id. RefuseUndeclared applies it from
Validate's Claim, which every cache write passes, to what the home store
holds at the key: a foreign record or one held under an undeclared id.
RefuseOverwrite and its two Push calls are deleted.
Red until rewritten: ForeignRecordTests.AWriteOfTheRecordItselfStoresItUnderTheTypesOwnId

Delete RawBytes from CultPersistedRecord and CultSchemaCatalogEntry, with every
drop-on-assign hook and the catalog's content guard. A decoded record or snapshot
carries no stored bytes, so an in-place edit of its payload or overrides can never
be shadowed by cached bytes, and the public snapshot and record serializers encode
every record from its fields.
SingleFileBackingStore now reads through ReadStore, which returns the snapshot and,
parallel to it, the exact slice the file holds for each catalog entry and record. Its
durable index keeps, by record key, that slice and its SHA-256 (hashed when a
comparison asks), which is the record's version. A write re-encodes every record
the writer staged and copies every other record, and every catalog entry it keeps,
as the slice the file holds. The directory store keeps its manifest's catalog slices
the same way. SerializeSnapshot/DeserializeSnapshot hooks become
SerializeStore/ReadStore plus SerializeCatalogEntry.
A staged but unchanged non-canonical record is now re-encoded canonically and gets
a new version; an untouched one keeps its bytes and version.
Tests: in-place edits through the snapshot API (payload, override) and through a
held document (collection, nested object) are written as edited; an untouched
non-canonical record survives a neighbour's write byte for byte; a staged one is
re-encoded. The cost test counts record hashes.

A record read from a store file carries the bytes it was read from (CultPersistedRecord.RawBytes, dropped when any field is
assigned) and is written as those bytes, the way a schema catalog entry already is. A version is therefore the SHA-256 of the
slice the file holds, whatever legal encoding its writer chose, not of C#'s re-encoding, and a write that copies a record leaves
its bytes and so its version alone. The contract says exactly that, so the parity cuts port it literally.

A record's bytes cannot say whether it holds an element id (an id is an ordinary keyed
string), so the per-record fact decoded by whichever type loaded the record was a split
authority: a narrower type unmarked a v3 store over bytes holding ids. HeaderForWrite is now
a pure function of the durable header, the HoldsIds of the records the write encodes, and
whether it copies any record forward: a write that copies keeps a marked header, a write
that encodes every record decides by content. The directory store takes the same rule.
Also pins the three Low test findings deferred from c2a-write-set s3: the reload cause is
observed by type and message, the author's own Expect after a commit, and the directory
store's re-mint branches.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The directory store wrote an earlier storedAt over a later record it replaced, against the contract.
CacheBackingStore.StoredAtOver is now the one re-mint; the single-file apply and the directory
generation write both call it. A foreign refusal passes the reload's cause to
CultSchemaConflictException as its inner exception. Per-commit build not verified.

New WriteSetTests (single-file and directory stores, flush and commit): another writer's write and
removal survive, a store that appeared after open is kept, an unstaged in-place change is not
written, a copied record keeps the catalog entry the store holds now, an entry's unknown trailing
fields survive byte for byte, conditional and unconditional commits write the same bytes, the
header drops only when every copied record is known id-free, v2 exactly with a variant. Mesh: a
write copies neighbours forward and replaces only its key. The lay-back and whole-view tests and
the flush-restamp tests are rewritten or removed with the rules they pinned.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
SingleFileBackingStore.ApplyWriteSet replaces WholeView and ReplaceDurable: under the lock, from the
durable snapshot read there, it removes staged removals, writes staged upserts and copies every other
record and the catalog entries they reference unchanged. PushAll, CommitBatchCore (conditional and
unconditional, one apply) and CultMesh's write call only it. Catalog entries read from a store keep
their exact bytes and are written verbatim while their decoded fields are unchanged. Derive no longer
lets a registered entry publish an id nothing staged sits under. HeaderForWrite is the one header rule
for the single-file and directory stores. A write is judged against variants another writer left in the
file. Tests of the deleted rules are rewritten in the next commit.

R1's rules win where both sides decided the same question: a zero-byte file is
not a store (refused as unreadable in every runtime), only nothing at the path is
empty, a dangling link is an I/O error, refusals never echo stored values and echo
a header only as cultcache.store.v<digits>, writes report Rejected, NotReplaced
and ReplacedNotDurable. C2a's rules win on what it added: the v3 element-id
header, variants, whole-file proof, typed unreadable errors in C#, TypeScript and
Python. Rust keeps R1's CultCacheStoreUnreadable{path, kind}; C2a's
StoreUnreadableError is deleted. The readability manifest's zero-byte row is
refuses x4.
