SerializePayload takes the declared type. A call attaches its registry under the store's gate and restores the previous one, so no call leaves a registry on the store. Not yet run; the next commit set is verified on Yggdrasil.

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.

C2a's StoredVersion owns the same identity and deletes both. No consumer outside CultLib uses them,

A protected static mark let any subclass mark another store's or cache's

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.

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.

IsLeaf, IsObjectType and DictionaryValueType are deleted. Classify(declared) says Leaf, Map
(IDictionary<,> or IReadOnlyDictionary<,>), Sequence or Owner; a keyed struct is walked as an owner and
is never an element. Plan and Holds take the declared root type and follow declared member types, so a
member declared object or a subclass's extra members under a base-typed member are neither minted into
nor read. Minted path text is unchanged.

_readHoldingIds and the pull's Holds walk are removed in the same commit that adds
SingleFileBackingStore.CopiedHoldIds: under the store's lock, while the header on disk is
unmarked, every plain copied record the writer's registry claims and whose type reaches an
object list is decoded, and the first holding an id marks the store. Positive-only, never
refuses a write. CultMesh's typed write attaches the registry its payload was encoded with;
the raw write attaches none. Contract text states the rule and its residual.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
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.

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).

CultCache mints storedAt from an internal Clock (default the wall clock); the vector writer pins it, so
union-surface.cc is regenerated in process and byte-compared on every run. The gate test sets the switch
itself and writes only a probe, so it neither skips nor touches a committed vector.
This commit does not pass: union-surface.cc still holds the old wall-clock stored-at; the next commit
regenerates it. Builds.

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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Remove and a committed batch removal of a key the cache does not hold ask every
store whether it carries a foreign record there (RefuseUndeclared); one that
does refuses with the typed schema conflict instead of Remove returning false
and Commit returning Committed over a record the store still carries.

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.

The persistence contract's relabel paragraph is replaced by ownership by
declaration: a record read through the catalog's schema name or a persisted
entry's list is read-only, and declaring its id claims it. CultForeignRecord
says no type can read it; the write APIs and MintElementIds name the refusal.

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.

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.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
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.

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.

ApplyWriteSet re-mints an upsert's storedAt when the durable record it replaces is not

CacheBackingStore.Refuse reloads the refused and moved keys through Loaded and only
then unstages them, or changes nothing; RefuseForeign calls it. A write into a store
that holds or would hold a variant lands only while the durable record headers equal
what this store last read (_lastRead), else CultWriteConflictException. SameStoredIdentity
is the one identity predicate.

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.

SingleFileBackingStore gains ReadDurable and ReplaceDurable (internal): CultMesh's read and write
helpers reach the one reader, <file>.lock and the unique-temp atomic replace through them. ReadDisk
decides absence from the path's attributes, so a directory at the path is an IOException, not an
empty store. Includes the directory clause that the spec lists as a separate step.

Opening a junction whose target is gone fails with UnauthorizedAccessException, not the
IOException the dangling-link rule promises. ReadDisk now turns that into the same
IOException. The dangling-link tests build a directory junction (mklink /J), which needs
no privilege, and the file-symlink cases skip where the account cannot create one.
The fixture removes links before its recursive delete.
