Soul F5. F7 (operator, 2026-09-30): "Schema aliasing sounds like a really
bad idea, I support retiring it." CultNetDocumentRegistry.Register wrote
both maps unconditionally, so the last binding for a schema id won.
- Register refuses a binding whose type already holds another schema id,
or whose schema id another type holds, with the reference runtime's
CultSchemaConflictException: the new binding's schema id, both document
types, an empty record key. Nothing is bound on refusal. Binding a type
to the schema id it holds again replaces the binding. This matches Rust
(fc3f3ee5) and Kotlin.
- Tests: both claimant shapes in both orders with two bindings ahead of
the holder (F6/M11), the first binding intact afterwards, and a same-type
rebind replacing.

Soul F8 (M6, M7 survived): node.get, getRequired and put return the
object the cache holds, as C# and Python do (Rust copies). That is the
behaviour that ships.
- The README says the returned object belongs to the cache and must not be
mutated, and shows the put-a-new-value pattern.
- A test pins it: two reads return the same object, put resolves to that
object, and the caller's own value is never the one held.

Soul F7 (P9): a catalog holding two documents of one type answered a typed
lookup with the last one added, and nothing else could name the other. Two
documents of one type under different keys stay legal.
- CultMeshDocumentCatalog.tryDocumentById and documentById look a handle up
by its document id, the key the catalog already holds handles under
(it defaults to the record key).
- The publication-catalog test addresses both synced documents by id
instead of documents[0] and documents[1].

Soul F3 and F4, and F1 in CultMesh's schema descriptor.
- The schema descriptor built from a definition uses schemaIdentityOf, so
a handle's schema id is the id the cache stamps.
- Store documents (F3): a handle reads the record under its schema id, or,
for a definition, under an id the definition lists as compatible, as the
cache resolves it. The catalog-entry name/version match and both parse
fallbacks are deleted: a record under another id is not this document,
whatever its payload parses as.
- Peer snapshots (F4): syncDocumentFromPeerSnapshot and definition-named
peer-snapshot handles take the peer's record at the key under the type's
schema id only. The shape filter is deleted and no match is not-found.
P8a (syncing A at k while the peer holds only B at k overwrote the local
B and then threw) and P8b (a peer's C stored as A) write nothing now.
- HELD: a peer-snapshot handle named by a bare schema-id string still takes
the first record at the key. Eve Electron reads the C# Aetheria daemon
that way (EveElectron src/cultmesh-provider-client.mjs:129-142): the
daemon stamps SHA-256 schema ids and the client asks by
"gamecult.eve.provider_advertisement.v1", so only the fallback finds its
records. How a TS reader names a C#-hosted schema is raised as a fork;
the fallback goes when it is ruled.
Tests: the store- and peer-snapshot tests that asserted shape routing are
replaced by tests of the refusal, including P8a and P8b, and one that pins
the held fallback.

Soul F1, F2 and F3 on the registry. The F2 principle (operator,
2026-09-30): "CultCache never destroys or relabels a record it doesn't
understand; keeps it byte-for-byte, refuses writes that would overwrite it."
- F1: the registry derives every binding's identity with cultcache-ts's
schemaIdentityOf, so it stamps, refuses and resolves exactly as the cache
does. P1 (A with schema name "p1.shared", B with schema id "p1.shared")
is now refused by both.
- F2a: an id nobody owns resolves to the one binding that lists it as
compatible. Several listers and no owner is a SchemaConflictError naming
the id and the listers, whatever order they were registered in; an owner
beats every lister. This is refused at resolution, as the cache refuses
it at load, not at registration: refusing at registration would make the
outcome depend on whether the owner was registered before the listers.
- F2b: version inference is deleted. "p3.note.v7" no longer resolves to
the type named "p3.note" and gets relabelled "p3.note.v1".
- F2c: a schema version string, and a schema name, are not ids. Snapshot
filters, typed puts and deletes, and raw puts match only declared ids.
- F3: a raw record under an id no binding declares is refused. The
registry no longer tries each binding's parser and stores the record
under the first that accepts it (P5: an identity parser registered first
took everything).
- The dead resolvePayloadSchemaVersion helper is gone.
Tests: the three shape- and alias-routing tests are replaced by P1, P2,
P3/P4 and P5 as behaviour tests. The one-type-per-schema test registers two
bindings ahead of the holder (F6/M11).

Soul F1 (hold on 98999997..6e47710e): the cache stamped records with
schemaId ?? schemaName ?? type, while the CultNet registry and CultMesh's
schema descriptor used schemaId ?? type. A definition that set only a
schema name was stamped one id by the cache and bound under another by the
registry, so its records could land on a peer as a different type.
- schemaIdentityOf(definition) returns the schema id, schema name, schema
version and every id the definition answers to (its own first). It is
exported, and it is the only place that derivation lives.
- The cache's catalog entry is built from it; nothing else changes here.

Stryker on 43ed9396..3763a53c left 20 survivors, in two places:
- cultMeshCatalogWriteArguments. No test wrote through a catalog's
replace or submitPrediction, so which argument was the context went
unobserved. A test now writes through both, in every calling form,
and checks the context and value that reached the document.
- The catalog refusal's schema names and message. The refusal test now
checks both names and that the message names both types.

4002a996's refusal caught the self-test itself: the reconciliation block
registered kotlin.reactive_note beside kotlin.reactive_note.ui under one
schema id in one cache. The block tests reconciliation, not two types for one
schema, so its note is now kotlin.reconcile_note under its own schema id.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
43ed9396's type test caught it: TypeScript inferred the catalog value type
from a written value or an expected result through the conditional's false
branch, so replace and submitPrediction accepted any value and an annotated
collection read took the annotation as its type. The false branch is now
NoInfer, so only a definition or an explicit type argument decides it.

Stryker left one survivor on 9adea366: emptying the refusal message. For a
same-type claimant the message did not name the schema id at all. It now
names the claimant's schema id in every case, and the refusal test checks
that it does. The message is built from document types and the schema id
only; registration carries no record, so no record value can reach it.

F7 (operator, 2026-09-30): "Schema aliasing sounds like a really bad idea,
I support retiring it." CultCache.register wrote its type and schema maps
unconditionally, and put, get, getAll and delete register implicitly, so one
Kotlin cache could hold two types for one schema and codecForSchema answered
with the last.
- register refuses a codec whose type already holds another schema id, or
whose schema id another type holds, with the new
CultSchemaConflictException (schema id, both document types, empty record
key), the Kotlin counterpart of the other runtimes' typed conflict. The
implicit registration in put, get, getAll and delete goes through the same
check. Registering the same type for the same schema again stays allowed.
- Self-test: other-type same-schema and same-type other-schema claimants,
through register, put, get, getAll and delete, each in a fresh cache; the
first codec still answers for its schema afterwards.

F7 (operator, 2026-09-30): "Schema aliasing sounds like a really bad idea,
I support retiring it." CultNetDocumentRegistry::register inserted into its
type and schema-id maps unconditionally, so the last binding for a schema id
won, as the TypeScript registry did before 9adea366.
- register returns Result and refuses a binding whose type already holds
another schema id, or whose schema id another type holds, with
cultcache_rs::SchemaConflictError: the new binding's schema id, both
document types (a binding carries no schema name), an empty record key.
Nothing is bound on refusal. Binding a type to the schema id it holds
again replaces the binding.
- Call sites propagate the refusal: the cultmesh-rs registry macro, the
interop peer example, and the tests.
- Tests renamed to what they test: raw snapshot replication hydrates the
receiver's own type for the schema; a reactive document coalesces direct
member writes.
- New test: both claimant shapes in both orders, the first binding intact
afterwards, and a same-type rebind replacing.

F7 (operator, 2026-09-30): "Schema aliasing sounds like a really bad idea,
I support retiring it." A catalog indexed handles by schema id and by schema
name and version with plain map writes, so a handle of another type for a
held schema silently replaced it for every lookup by schema alone.
- Document and collection catalogs refuse, with the SchemaConflictError the
registries use, a typed handle whose type differs from the one holding its
schema id or schema name and version, or whose type already holds another
schema id. Nothing is indexed when a handle is refused.
- Allowed: handles of one type for one schema (one per record), the same
handle again, and a handle without a type, which claims none.
- Test: other-type same-id, other-type same-name-and-version and same-type
other-id claimants, both orders, via add and via construction, for both
catalogs; the first handle still answers afterwards.

The deleted parse option was the only thing that typed a catalog lookup, so
every caller had to name the value type. Catalog methods now take the schema
argument as a type parameter: a CultCache document definition yields its own
value type, an explicit type argument still wins, and a bare schema
descriptor yields unknown. CultMeshCatalogValue names that rule.
- Document catalog: tryDocument, document, latest, replace,
submitPrediction, authoritativeWriter, predictionWriter, watch.
Collection catalog: tryCollection, collection, latest, watchChanges.
- The two copies of the (value, options) / (context, value) argument split
collapse into cultMeshCatalogWriteArguments, and the typed lookups share one
private #require per catalog.
- Tests: the three reads that named their type infer it again. A type-level
test pins inference for reads, rows, watches, writes and writers with
@ts-expect-error on wrong assignments.

The catalogs' parse option went with asSchemaAlias, and with it the only
thing that inferred a catalog lookup's value type. Three test reads now pass
the note type explicitly, as a caller does.

F7 retires schema aliasing (one type presented as another for the same
schema). The Rust and Kotlin rows called their snapshot hydration "same-schema
alias" hydration. Both decode a raw record by its schema id into the one type
the receiving runtime registered for that schema; neither has a handle
aliasing API. The rows now say that.

F7 (operator, 2026-09-30): "Schema aliasing sounds like a really bad idea,
I support retiring it." One type owns a schema, so a handle never needs
presenting as another type for the same schema. Parity with C# 1e045502.
- Delete asSchemaAlias from the document, bound document, collection and
bound collection handles, and cultMeshSchemasAreCompatible, which only it
and the catalogs' alias step used.
- Document and collection catalogs answer a typed lookup from that type's
handle or not at all. A descriptor without a type is still looked up by
schema id, then schema name and version. The parse option on every catalog
method existed only to convert an aliased value, and is deleted.
- CultMeshNode passes the caller's definition to its cache. The node no
longer resolves another type's definition by schema id, and no longer
re-parses values into the requested type, so a type the node did not
register is refused by the cache. node.get and node.put now return the
cache's own value, as CultCache.get and put do.
- Tests: the noteAliasDocument fixture is deleted. Tests that used it for
publication, sync, snapshot, store and prediction paths now use
noteDocument. otherTypeForNoteSchema stands for another type claiming the
note schema: catalogs do not find it, and a node refuses it on every path
and refuses to register it beside noteDocument.
- README stops documenting node aliasing.

F7 (operator, 2026-09-30): "Schema aliasing sounds like a really bad idea,
I support retiring it." CultNetDocumentRegistry.register silently replaced
the binding for a schema id, so two types could claim one schema and the
last one registered won.
- register refuses a binding whose definition claims a type, schema id or
schema name another bound definition already holds, with the
SchemaConflictError CultCache uses for the same refusal: the new
definition's schema id, both schema names, an empty record key.
- Binding the same definition again still replaces its binding, and a
definition listing another's id as compatible is not a second owner.
- Test: identical-id, same-name and same-type claimants refused in both
registration orders, leaving the first binding in place.

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.

F7 (operator, 2026-09-30): "Schema aliasing sounds like a really bad idea,
I support retiring it." One CLR type owns a schema, so a handle never needs
converting to another type for the same schema.
- Delete AsSchemaAlias from the document and collection handles and their
interfaces, with the MessagePack round-trip converters only it used.
- The document and collection catalogs look a typed handle up by its type.
The schema-name/version fallback existed only to find a handle of another
type and alias it.
- Tests: the MeshNoteAliasDocument fixture is deleted. Tests that used it
for publication, sync, snapshot and prediction paths now use
MeshNoteDocument; the one test that only checked alias refusal is deleted.
Catalog tests check a type with no handle is not found.
- public-api.md stops documenting aliasing; a stale comment in
ReadDocumentFromSnapshotResponse that cited the fixture is trimmed.

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>
Owner beats lister, as in C# and Python. The cache kept one definition per id,
own or compatible, and refused a second with a plain Error, so a v1 definition
could not stay registered beside a v2 declaring v1's id (Soul F8, cult-cache.ts
registration). Now a definition owns its schema id and any number may list it:
a record resolves to the owner, else to the one lister. Several listers and no
owner name no single definition, and the load is refused with
SchemaConflictError naming the id, the record key and the listers.
Every registration refusal is now SchemaConflictError (Soul F10): a second owner
of one id, a second definition with one schema name, and a different definition
for one type. Each names the new definition's id and both schema names.
SchemaConflictError takes an optional message for these uses.
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; each of the three refusals is
a SchemaConflictError in both registration orders.

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

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>
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.

The C# interop note declares a compatible id and the peer gains a rewrite mode; the TypeScript

A type that failed to build a descriptor poisoned the shared registry's discovery of every
loaded document. A blank id is now filtered like the type's own id, and the test declares one.

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.

The previous cut let any supplied type name a schema id over the arrived one, which let a raw
envelope of another type retype the records under an id (the dynamic-payload test refused it and
failed). A rename under a stable id is a write of the registered type that owns the id; a Rust
registered type's id is its entry type, so a supplied envelope whose type is its schema id names
the id and any other type under an occupied id is refused, typed, with the file left as it was.

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 and the cross-tier
refusal; a cross-runtime test has TS write a schema renamed under a stable id and TS, Rust and
Python open it.

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.

pull_all_backing_stores resolves a record to a registered type by its schema id (a registered
type's id is its entry type) before the catalog name is tried. The writer tells the entries the
file already holds from the ones its caller supplies, and a supplied type names the schema id over
an arrived one, so a stable-id rename is not a conflict; two types of one tier under one id still
refuse the write.
Tests: a stable-id rename write, a renamed schema opening by id, and an id not overruled by a name.

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.

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.

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.
Changelogs for cultnet-py (removed export) and cultcache-py.

The directory store's preference for the entry being written was not pinned: nothing distinguished the entry's hash.
