Wrap and the Outcome arms gain id slots (unit arms become one-slot id records);
the Python unit-arm codec behaviour is kept on a separate unit 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.

leaves.py (string, boolean, bytes, int32, int64, float32, float64, any, list, array, nullable, lazy) held to the
numeric-leaves vectors. Removed: DatabaseEntryField.many, callable codecs and _resolve, the System.Object literal,
the present-nil default, the union's nil pass-through, interop.py's hand-written catalog. A float32 keeps its width
through _pack_tree. Nil is refused unless wrapped in nullable; a default fills only a slot past the payload's end.

The tree walk counted only list, tuple and dict, so a codec whose tree used deque,
mappingproxy or another abc container was unbounded. Every Mapping, Sequence and Set
that is not text or bytes now counts. RecursionError from a user encode or decode,
and from the JSON decoder, reaches the caller as itself with its traceback; only
msgpack's StackError (raised by depth alone) is mapped to the depth refusal.
All commits build.

Removes the equivalent continue in the walk (the stack only ever holds containers).
Pins the exact refusal text on the RecursionError and StackError paths, both sides,
and that the validator receives the written and the decoded value. Every commit builds.

DatabaseEntryField validates its key in one place (0..MAX_SLOT_KEY, no bool), so
database_entry_field, direct construction and field tuples share the rule. A record
shorter than its declared slots no longer refuses a missing slot: the slot is nil
and its default applies, as the C# reference reads it. define_union refuses True
and False as arm keys, each pinned alone. Every commit builds.

Iterative container count over the decoded and the encoded tree (MAX_PAYLOAD_DEPTH,
CultCachePayloadDepthError); msgpack StackError and RecursionError map to the same
refusal. Union decode names an out-of-Int32, non-integer or nil-slots arm as the
reference does. Fixture arms Wrap, Floor, Ceiling; loop over bounds-outcomes.msgpack.
Pins the bool arm-key refusal's callers in the vector loop only; every commit builds.

define_union and define_record_codec share the slot logic of define_database_entry_type
(one record codec); a field takes a codec, many, or a thunk for recursion. Unknown arm

Mutation survivors on the merge's refusal text (the two readable formats, the
unrecognised-header description, the record-slot refusal) had no test pinning them.

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.

The five-slot refusal echoed a non-string key or schema id with repr, quoting
stored bytes. A string is named; anything else is described by its type.
A push through a live link replaces the link with a regular file. A test
named for R3 pins that until R3 decides whether writes resolve or refuse
links.

An unsupported header is echoed only as cultcache.store.v<digits>; any other
is described by its byte length, since the bytes are the store's.
A read that found nothing through a dangling symbolic link returned an empty
store, and the writer then replaced the link. Both stores now share one read
rule: only nothing at the path is absent. JsonLinesBackingStore also drops
`Path.exists()`, which reported a symlink loop or a file-as-parent as absent.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
`Path.exists()` returns False for ELOOP and ENOTDIR, so a symlink loop or a
file where the parent directory should be read as an empty store. The read
now catches FileNotFoundError only. An existing zero-byte file is refused
with ValueError, like any other undecodable store, matching the Rust and C#
runtimes. `[0x90]` stays an empty legacy store.
Refusal text no longer points at a variant-aware runtime: an unsupported
header names the format found, and a v1 record with a fifth slot says the
file is not a valid store.

Owner beats lister, as in C#. A document owns its schema id; others may list it
as compatible beside its owner, in either registration order (batch 9 refused
any overlap, which forbade keeping v1 beside a v2 that declares v1's id; Soul
F8). A record resolves to the document owning its id, else to the one document
listing it. Several listers and no owner name no single document, and the load
is refused with SchemaConflictError naming the id, the record key and the
listers: refusing at registration would depend on whether the owner had
registered yet.
Every registration refusal is now SchemaConflictError (Soul F10): a second owner
of one schema id, a second document with one schema name, and a second
definition of one document type. Each names the new document's id and both
schema names and document types. Before, the last two raised CultCacheError.
Tests: an owner and a lister register in both orders and each reads its own
records, and a lister alone reads the owner's id; two listers register in both
orders, a record under their id is refused typed without its owner and is the
owner's with it, registered before or after them; two owners, one schema name
and one document type twice are each refused as a schema conflict.

register_document_type refuses a document whose own or compatible ids overlap
another registered document's, raising SchemaConflictError (empty record key,
both schema names, a message naming both document types), as TypeScript does.
Before, the record resolved to whichever document the dict held first (Soul F4).
With one carrier per id, resolution by id is a single pass. SchemaConflictError
takes an optional message for this use.
The test that pinned owner-over-lister resolution inside one cache becomes a
refusal test in both orders; shared compatible ids and a shared own id (neither
declaring its own) are refused in both orders.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A record now resolves to the document that owns its schema id, else one that lists it as
compatible, before the catalog name is tried; a schema renamed under a stable id opens, and an id
that names one document is not overruled by a name that names another. The name resolves a record
only when no local document has the id.
The writer refuses a write that would change which type an existing record resolves to, unless the
entries of both the existing records and the written ones own the id (a rename, the registered
descriptor wins).
Tests pin the arrived-overwrites-registered guard in both id orders, the content-hash tie-break
against the compatible-list order, sorted id processing, the cross-tier refusal and the rename, and
a cache whose document does not list the id a loaded record sits under.

Two entries of one tier that share an own id are refused when the id is carried, so a refusal at dedupe could never fire.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
A read-back record's type is its schema's name and a supplied one's is the document type, so records of different tiers are never
compared; two supplied (or two arrived) records of different types under one id still refuse the write.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Every writer (C# single-file and directory, TypeScript, Python; Rust already did) chooses, for each schema id a record carries, one
entry that publishes it: the entry that owns the id (a registered descriptor, else an arrived entry), else one that lists it as
compatible. A registered descriptor wins over an arrived entry with the same own id. Entries are written as chosen, with no union of
compatible ids and no dependence on arrival order; an entry no record needs is not written. Two entries of one tier that share an own id
and disagree on the schema name, records of different types under one id, or a record no chosen entry publishes refuse the write with a
typed error (CultSchemaConflictException, SchemaConflictError) naming the id, the names and a record key, and the store is left as it was.
CultSchemaCatalogEntry.MergeById and the Python and TypeScript merge paths are gone. A cache-held record unchanged since the file was read
is rewritten under its registered id (C# single-file and directory), so an entry that lists an older id is not needed to publish it.

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

cultnet-py resolves a raw record whose schema id no document lists by the schema version its payload opens with, and three
cultmesh-py tests (foreign UI-generated ids) depend on it, so that resolution is restored pending a ruling. The compatible-id
replication test goes through the real apply_raw_document_record and the reopened store.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
put_envelope, put_envelopes and load stamp the registered schema's id, and the store writer publishes every record's id, so a
replicated record under a compatible id no longer leaves a store nothing can open. cultnet-py resolves a raw record by the schema
ids its documents list and nothing else.

Rust, TypeScript and Python each had a test that a record missing its catalog entry is recovered from its payload; each now asserts
the store is unreadable.

The refusal is a ValueError subclass with the cause chained. A store with more than three slots is refused instead of read.
The readability test walks every vector in the folder, asserts the error type and cause, the header a replaced file carries
and what it holds.

Rust's read path let a legacy envelope array with trailing bytes through when the

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
persistence format contract now marks v3 by content and states the readability
rule.

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.

The behaviour was already a refusal that leaves the file untouched; now a test fails if a rewrite
ever reads the disk header less strictly than a load does.

push_all overwrote a v9, variant-v2 or variant store with a v1 file, dropping its variants; TypeScript and Python
refuse. The rewrite header now comes from the file's own prefix and shares one readable-format rule with the
decoder. TypeScript pullAll resets its header when the file is gone, empty or legacy, as Python does.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
TS pushAll wrote the header its instance last read (v1 when fresh) without reading the
file. It now reads the on-disk header first, as push and delete do through pullAll. Python
resets its remembered header when the file is gone or empty, so the disk decides.

A store that can hold element ids declares cultcache.store.v3. These runtimes pass payload
