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.
Not yet built or tested: verification follows in the next commits.

A pull runs only on a clean store, and a store is clean exactly when nothing is staged, so the pull's clear was redundant and is gone.

CacheBackingStore.RefuseForeign now decides, for both store kinds, which written keys a foreign record refuses, drops the
store's staged change and the cache's copy of each through the Loaded path a pull uses, and throws one conflict naming every
refused key. The single-file store tracks the keys staged since its last load or write, as the directory store already did, so
a clean copy of a record another writer made foreign is carried, not refused.

The file's record moves when only its storedAt or only its schema id differs from the loaded one; a
staged removal is refused and dropped with the rest; a refusal leaves staged what it did not refuse.

WriteGeneration left the refused key in the dirty and deleted sets, so every later generation
refused it. The refusal is now one check before any staging, shared by flush and commit, that
removes the refused keys from the pending sets. Tests cover both store kinds.

A whole-view write laid back the loaded bytes of an unclaimed record over whatever the file held,
reverting its owner's newer write and moving storedAt backwards. It now lays back only while the
file holds the loaded (schemaId, storedAt); a newer record is carried as the file has it and a
removed one is not written back. The v3 header is decided by records that are written as the cache
holds them, so a laid-back id-less record no longer marks the store. A document changed in place is
written as a write of the record, not dropped. A refusal drops the store's copy of the refused
records, so it no longer refuses every later write.
Does not build with the directory store untouched? It builds; the directory twin follows.

- The lay-back fixture gains an older entry listing the id ahead of the
one that owns it, and a test where another writer re-describes the id
after the load: a whole view (flush and commit) lays back the entry it
loaded. Kills the survivors in Publisher's own-id preference, the
laid-back entry's precedence in the written catalog, and the commit's
choice of that catalog.
- A store whose file is gone lists no foreign records.
- The registry's public resolution still refuses an unclaimed id, naming
the schema and the id (was NoCoverage).
- A directory load retried after a writer's commit lists each foreign
record once.
- Deleted LaidBack.ExceptWith(replaced): equivalent, since an upserted key's
new entry already carries what the cache would be told.

C2a F2, widened by Self: records and catalog entries a runtime does not own
survive its writes byte for byte. The schema-identity probe showed a C#
rewrite restamping every other runtime's record to its sha256 id and
dropping their catalog entries.
- The single-file store remembers, per key, a record it loaded under an id
its type neither owns nor declares compatible (resolved through the
catalog's schema name or an entry pointing at a local id), with the entry
that published it. While the store still holds the entry it loaded, a
whole-view write (flush or unconditional commit) lays that record back
with its id, storedAt, bytes and catalog entry. A write of the record
itself still stores it under the type's own id.
- A record published by an entry under the type's own id is this schema's
and is re-encoded as before (the registered entry wins its own id).
- A laid-back record's load-minted element ids stay in memory only, so
MintElementIds still rewrites it.
- The rolling-deploy tests lose their premise: an older version's whole
view no longer sheds a newer record's member. They now pin that it lays
the record back and the newer cache's condition holds; the A-B-A test
keeps F6's defence through an explicit older write.
- Contract: the stamp and the lay-back rule in the persistence format.

The corrupt-store test pinned the old refusal of an unknown schema at open.
Under C2a F2 that record is foreign: the store opens, lists it, and opening
still rewrites nothing.

C2a F2, operator: "CultCache never destroys or relabels a record it doesn't
understand; keeps it byte-for-byte, refuses writes that would overwrite it."
- The registry's claim decision (Claimant) is split out of resolution. It
never decodes or compares shapes, so a store classifies a record from its
header. The last branch, "No local CultCache schema matches", now means
foreign instead of a refused load.
- Both store kinds keep a foreign record out of the cache and list it in
CacheBackingStore.ForeignRecords (key, schema id, catalog name, storedAt).
- Single-file store: a whole-view write lays back every foreign record the
file holds now, with its catalog entry, and keeps a marked header while it
carries one (it cannot see their ids). A staged write, a commit (onto the
file or whole view) and a whole view over a key the file holds as foreign
refuse with CultSchemaConflictException naming the key and id. A merge
judgement never decodes a foreign record, and one that replaced a held
record takes it away.
- Directory store: a foreign record's page is never read; a generation that
would replace or remove one refuses before any page is written.
- Contracts: hard rejection no longer lists "no compatible local schema
candidate"; the persistence format says what a foreign record is.

Pins the C# side of the cross-runtime rule the Rust, Python and TS runtimes

F7 (operator, 2026-09-30): "Schema aliasing sounds like a really bad idea,
I support retiring it." C# now holds one type per schema, as TypeScript,
Python and Rust already do.
- Delete IsExactWireAlias and the branch that registered an identical second
type by CLR type only. A second type with the same schema name and version
is refused with CultSchemaConflictException naming both types and the
claimed id, whether it is identical, declares other compatible ids, or has
other members. The untyped DuplicateSchemaRegistration refusal and the
separate SchemaIdClaimedTwice path collapse into that one refusal.
- Owner-beats-lister (batch 10) is unchanged: one type owns an id, others may
list it as compatible.
- The per-name version index stays; it serves v1/v2 of one schema name, not
aliasing.
- Tests: the alias-registration tests are replaced by one refusal test over
identical, re-declared and re-shaped second types, in both registration
orders.
- cultcache-store-composition.md drops the AsSchemaAlias stale-protection note.

Defends the id half of the whole-view restamp rule on its own: the record C# loaded
under v1's id is gone from the file when a v2 cache flushes it back, so there are
no stored bytes to compare, and only the changed id says it is a new store.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Batch 9 refused any overlap between two types' ids, which forbade the migration
CompatibleSchemaIds exists for: v2 declares v1's id while v1's class stays
registered (Soul F8). The rule is now owner beats lister. A type owns its own
schema id; any number of types may list an id as compatible beside its owner,
registering in either order. A record under an id resolves to its owner, else to
the one type listing it. An id no type owns and several list names no single
type, so a record under it is refused, typed (CultSchemaConflictException naming
the id and the listers), where it resolves: refusing at registration would
depend on whether the owner had registered yet.
A second owner of one id is still refused at registration, typed. A schema id
hashes the schema's name and version, so the only second owner is a type of the
same name and version, which the name-and-version check already meets; the
separate own-id lookup could never fire and is gone.
Tests: an owner and a lister register in both orders, the owner's id resolves to
the owner, the lister's own id to the lister, and without the owner to the
lister; two listers register in both orders, a record under their id is refused
typed with no owner and resolves to the owner with one, registered before or
after them; a cache with v1 beside v2 reads each version's records as its own
type, in both registration orders. The emitted-fixture note says why a fixture
is emitted now that v1/v2 pairs no longer need hiding from the shared registry.

A condition names a record by (stored schema id, storedAt), and that name must
say which bytes are stored. A single-file whole-view write (plain flush, or an
unconditional commit) re-encoded every record under its own type's id with the
storedAt it loaded, so the pair could name two byte strings: v1 shed a member
keeping storedAt, a second v2 cache restored v2's id keeping it again, and a v2
cache holding the original bytes committed its condition (Soul F6, A-B-A).
Now such a write stores a record under a later storedAt whenever it stores it
differently: under another id than it was loaded under, or with other bytes than
the file holds at that storedAt (a record written with the ids it minted at
load, for one). A record stored exactly as the file holds it keeps its storedAt.
The store's entries and the cache's take the id and storedAt the write gave them.
Tests: the A-B-A through commits and through plain flushes, with Expect and
ExpectUnchanged; a flush that re-encodes a record restamps the cache that
flushed (a condition holds straight after, SM12); a record stored unchanged keeps
its storedAt through commits and flushes; persisting load-minted ids gives a
later storedAt. The rolling-deploy test asserted v1's rewrite kept storedAt; it
now asserts a later one, since that rewrite is a new store of the record.

A plain record and a variant loaded under a declared old id pass Expect and
ExpectUnchanged while the file is unchanged, and again after a whole-view commit
rewrites them (the variant case pins the id surviving resolution). A directory
store pull rereads a record whose manifest id alone changed, so a condition on
it holds.

A directory-store record's identity on disk is its manifest entry, which is what
a commit condition compares; the page holds its own copy of the id. A load now
takes StoredSchemaId from the manifest, so a manifest rewritten under an older
id (AConditionOnARecordUnderADeclaredOldIdHoldsInTheDirectoryStore) is the id
the condition expects. Canonicalisation had hidden the page and manifest
disagreeing in that fixture.
The whole-view test's variant overrides its name: a variant may not share its
base's.

Registration refuses a type any of whose ids (its own, or one it declares
compatible) another registered type already owns or declares, with
CultSchemaConflictException naming the id, both schema names and both CLR types.
TypeScript already refuses this (cult-cache.ts); before, C# kept whichever type
registered first (Soul F4). An exact wire alias must now also declare the same
compatible ids: a type differing only in its declaration had it dropped when it
registered second (H4), and is refused the same way.
Exact aliases that agree in every respect still register by type, and a record
under their shared id still resolves to the first registered (H3). Removing that
would delete CultMesh's same-schema aliases; it is left for an operator ruling.
Tests: both registration orders for a shared compatible id, an owned id declared
by another type, and a same-schema type with a different declaration; an alias
with the same declaration still registers. The registry tests use the shared
EmittedDocumentTypes helper in place of their own.

Each stored document carries StoredSchemaId: the id its record sits under in its
store, the one it was loaded under until a write puts it under its type's own id.
Expect, ExpectUnchanged, the reload and merge identity checks compare
(StoredSchemaId, storedAt) with the store's bytes exactly. CanonicalSchemaId is
deleted: canonicalising the disk id let an older version's whole-view rewrite
(same storedAt, restamped to its own id, a member shed) pass a newer cache's
condition (Soul F1), and failed every condition on a record resolved by name or
through a file entry listing the local id (F3). A whole-view write marks every
record it wrote as stored under its type's id, in the store and the cache.
Tests: Soul's rolling-deploy probe as AWholeViewRewriteByAnOlderVersionFails...
(Mismatch for Expect and ExpectUnchanged, nothing derived lands, a pull shows the
rewrite and the retry commits); F3's H1, H1b, H2 pass Expect and ExpectUnchanged
when nothing changed; conditions after a whole-view commit hold for a plain
record and a variant. BareDeck is emitted at run time (EmittedDocumentTypes) so
the shared registry never sees it beside DeclaringDeck; the CanonicalSchemaId
tests and their Claimant fixtures go with the function.

A condition on a record under a declared old id is tested against the directory manifest too, and
a duplicate declared id is listed once. The merge-judging comparison keeps its plain schema-id
equality: a record it re-reads is only judged again, and no test reaches a difference.

The contract says the name a catalog entry carries is metadata and a schema renamed under a
stable id opens in every runtime that holds the id. The C# shape comparison refused any name
drift, so a record under a declared old id (the entry carrying another name and a different
content hash) or under a renamed stable id could not open. The comparison keeps the slot and
type checks; a record resolved by name has the same name by construction.

A type that failed to build a descriptor poisoned the shared registry's discovery of every

CultDocumentAttribute.CompatibleSchemaIds, as TypeScript and Python already name it. The
registered catalog entry lists the ids after its own, the registry resolves a record under one
to the type (its own id first, then the first registered type that declares it), and a
condition on a record compares schema ids through that resolution, so a record still under a
declared old id counts as the record the cache holds. The cache already stamps every record it
writes with the descriptor's own id; the store writers still change no identity, so a record a
commit does not rewrite stays under the id the file holds it under, published by the registered
entry. Without the declaration such a commit is refused, typed, as before.
Contract and XML docs describe the declaration.

Deleted the heuristic that rewrote a record the cache held "unchanged since read" (same key and
storedAt) under the registered id, in the single-file commit and in the directory generation. It
could overwrite a record another writer changed while keeping its storedAt. A commit onto a file
now writes its batch and leaves every other record as the file holds it; a record under an id only
an arrived entry lists is refused, typed, with the file left as it was. Deleted the directory
store's _durableCatalog, a second stale-able source of arrived entries beside the manifest read
under the lease.
Tests: the lost-update probe, the two refusals that replace the restamp tests, the
arrived-overwrites-registered guard in both id orders, the content-hash tie-break against the
compatible-list order, and refusal determinism across record arrival order.

cultnet-py's resolve_document_and_schema_id_for_raw_record is replaced by resolve_document_for_raw_record, which resolves the
document only; cultmesh-py keys previous values by the local schema id, so a snapshot under a compatible id or the schema name
reports an update with its previous value. Writers (C#, TypeScript, Python) merge same-id entries only when their schema names match;
another schema's entry is dropped or the record gets a default entry under its own id, and a record's own id is claimed before an
entry that lists it as compatible. The C# single-file writer prefers the entry being written now, as the directory writer does, so
name, content hash and members come from the registered schema and the compatible ids are the union. Vector:
compatible-before-owner-v3. A cultnet-py test's schema path no longer depends on the working directory.

Entries that share a schema id are one schema seen by different writers, so the writer lists every id any of them lists, in any
order: C# single-file and directory (CultSchemaCatalogEntry.MergeById), TypeScript and Python. Rust synthesises one entry per id and
has no such merge. An id that one entry owns and another lists as compatible names the owner in Rust, TypeScript, Python and the TS
inspector, as C# already did (own-id-over-compatible-v3). Also: a directory manifest in an unreadable format is the typed refusal
naming it, cultnet-py applies and reports a record under the local schema id, and Rust's error prints its cause once.

A record whose schema id the catalog lists only as a compatible id now opens (the cache resolved a persisted schema by entry id
alone). CultMesh's fallback to the older catalog-entry reader fires only for a store in that layout, decided by the entry's slot 5,
not for any decode failure, so a current-layout store with a malformed slot is refused as CultCache refuses it.
CultStoreUnreadableException.Path names the refused file. New vectors: compatible-id-only-v3 (accepted by all four) and three
current-layout catalogs with one malformed slot. The contract states the writer's invariant.

C# read such a store on flush and commit and refused it on open, with an untyped InvalidOperationException from the cache. The
store reader now refuses it with CultStoreUnreadableException, so open, flush and commit give one verdict, as Rust, TypeScript

CultStoreUnreadableException (a NotSupportedException) is the one refusal for a store file this runtime cannot read, thrown
by the single-file reader, the rewriting paths and CultMesh's reads, with the cause as the inner exception. The reader is exactly
one array of three slots (or an empty array): a header alone and an extra top-level slot are refused instead of read as empty or
skipped. CultMesh's older-catalog fallback is the same reader with the older entry reader, so it also requires one array.
Vectors: bad-body, header-only, missing-schema, variant-slot, extra-top-slot in the readability set, and a legacy-catalog store
with and without bytes after it for CultMesh. The persistence contract says what is true.

A rewrite replaces a file only when the runtime's own reader opens it. C#
drops ReadStoreHeader (a second, header-only verdict that let a flush replace
files the reader refuses) and asks DeserializeSnapshot from open, flush and
commit; the reader now requires exactly one array, so C# refuses bytes after
the store on read as TS and Python do. A zero-byte file is an empty store for
all three paths. CultMesh.WriteSingleFileDocument reads the file it replaces
through the Mesh reader before writing. Rust reads and rewrites through one
classification (trailing bytes refused on read; a non-store first slot must be a
legacy envelope array the reader accepts). TypeScript checks a legacy array with
pullAll's own decoder before replacing it. Python already conformed.
Shared byte vectors and per-runtime verdicts live in
tests/vectors/document-variants-c2a/readability; every runtime's test reads
them. Holds gains second-dictionary-value and second-list-item cases. The

CultElementIds.Holds is the one fact a store marks its header by; a test now

C# ReadStoreHeader refused a first-slot string without the cultcache.store.
prefix and then ran RequireSingleFileFormat, which refuses every string that

A rewrite read the header of the file it replaces but not whether the file was
a store: C# ReadStoreHeader skipped one value and ignored bytes after it, and
took a non-array value or an array whose first slot is a string that is not a
store header for a headerless legacy file (so did the C# Mesh raw write, which
uses it); TypeScript's pushAll took any non-array value or non-header first slot
for v1; Rust ignored bytes after the array.
The rule, one per runtime: a file is a store on rewrite only when it is exactly
one complete MessagePack array. Bytes after it, a value that is not an array,
and a first slot that is a string but not a header this runtime reads are
refused, and the file is left untouched. An empty file and a legacy envelope
array (first slot not a string, empty included) carry no header and are still
rewritten.
- C#: ReadStoreHeader refuses non-array values, trailing bytes and a non-header
first string, with a NotSupportedException naming which.
- TypeScript: storeHeader (store-format.ts) decides the rewrite header;
@msgpack/msgpack's decode already refuses trailing bytes.
- Rust: store_header(bytes, whole) walks with a cursor; the rewrite path asks
for the whole file, the read paths keep reading as before.
- Python: push_all already reads the whole file (unpackb refuses trailing
bytes, the legacy decoder refuses anything but a list of maps); pinned by a
test.
Tests in each runtime run the same file matrix (truncated, trailing, scalar,
map, string first; empty, empty array, legacy), plus a C# unconditional commit
over a store with trailing bytes and the C# Mesh raw write.

SingleFileBackingStore.PushAll replaced the file without reading it, so a
truncated store or one in a format this runtime does not read was clobbered,
where Rust, TypeScript and Python refuse. PushAll now reads the header of a
non-empty file under the lock before it writes; a file it cannot read throws
and is left as it was. An empty file and a legacy envelope array carry no
header and are still replaced.
The header is read by the store's codec: SingleFileBackingStore gains a
protected virtual ReadStoreHeader (default: read the whole snapshot), and the
MessagePack store overrides it with
CultDocumentMessagePackSerialization.ReadStoreHeader. An unconditional commit
reads the file it rewrites through the same check.
Doc text: last-writer-wins now says it holds only over a file the writer can
read (CultCache.cs PushAll comment, cultcache-persistence-format.md
"Conditional commit is the only safe multi-process write" and writer rule 4,
cultcache-store-composition.md "A plain flush and an unconditional commit are
last-writer-wins").

A record's HoldsIds was decided by its admission and trusted afterwards, so a
document changed after it was committed, or loaded and changed in place,
flushed under the header its admission-time content needed (Soul P7, P10).
HoldsIds now has one owner, the record's stored form, read when asked:
- a plain record: CultElementIds.Holds over its document, a scan that reads
and refuses nothing;
- a variant: the same scan over each override value, decoded with the codec
the record was built with (the cache's, or the attached cache's at load);
- a variant built with no codec (a store that loaded it with no cache) cannot
see its values and counts as holding an id, so a store never writes an
unmarked header over ids it could not see.
Cut: the admission path that set HoldsIds on plain records, on variants from
their resolved copies, and on flattened records; the internal setter and its
backing flag; IdPlan.HeldIds and IdPlan.HoldsIds. The Mesh typed write reads
Holds off the document it writes. Admission keeps its own id counting
(IdPlan.Count) for IdsInMemoryOnly.
Tests: an id added to a committed or loaded deck after admission marks a
PushAll v3, and taking it away unmarks it; a variant read without a codec
counts as holding ids while the same record read with one does not.

One conflict, at the end of Admit in CultCache.cs. The branch had added the
IdsInMemoryOnly marking of a load's minted ids before Apply; main had turned
the thread's hold into a Hold carrying Changes and Failures and run the
journals right after Apply. Both are kept, in that order: the marking touches
only the records and runs no user code, then Apply mints the Sequences, the
hold records the changes, and the journals run under the gate.
Id planning and Project do not collide. Ids are planned and applied first,
Resolve (variants, then Project, then the name and index rules) reads the
filled documents, land runs, and only then Apply mints. A Project getter that
throws is caught by the same handler that undoes the id plans, so a refused
admission changes no document and mints nothing.
