A variant record stores [baseKey, overrides[]] in record slot 4 and an empty
payload; the cache resolves it against its base inside the hold that admits it or
any record on its base chain, and re-resolves dependents in the same Apply, so a
base change reaches its variants with contiguous sequences and no stamp. Plain
Upsert at a variant key is refused (Flatten is the explicit way); cycle, missing
base, different concrete type, evicted base with survivors and a name that
shadows the base are refused naming the keys. Overrides of a dropped slot or an
undecodable value are ignored with a warning and reported as compatible drift.
The store writes cultcache.store.v2 only when it holds a variant and reads v1 and
v2. The codec pair CultInspectorModel took becomes CultCodec, shared with the
cache, which needs it to clone documents and overlay override values. The
directory store, CultMesh single-file reads and CultNet row building refuse a
variant by name until their own cuts.

Key identity serialized a key with the options of the key type's own
assembly, but the store writes it inside the document with the document
assembly's options, [CultCacheFormatterResolver] resolvers included. A key
that failed to serialize fell back to comparison by ToString.
The inspector codec now takes the owning document type, ReplaceKey and
FreshKey take it, and a key serializes as its declared key type under that
document's options, the store's own path. A key the document cannot
serialize is refused with a notice; the text fallback is deleted.
The comment and README said "the dictionary's own comparer"; it is the
rebuilt dictionary type's default comparer, and now says so.

A refused key and an unavailable fresh key are now the model's answer:
ReplaceKey returns the kept key with the notice text, FreshKey returns
null with its notice, and IMGUI only shows them.
A key is taken when another serializes the same or when the dictionary's
own comparer calls them equal, so 0.0 against -0.0 is refused instead of
throwing in BuildDictionary.
Keys never actually compared by bytes: the Studio handed the model the
document codec, whose registry guard throws for any non-document value,
so every key fell back to ToString. CultCacheMessagePack now builds the
model with a value serializer, and the Studio and tests both use it.
Tests pin the comparer rule, the unchanged-key rule (an old empty
reference key survives an edit of its value) and serialized identity
(keys whose ToString collides); each fails with its rule removed.

Cut 3 of the CultCache migration (Aetheria docs/cultcache-migration-cut.md, 2.1
and 2.2). One commit, because routing, the batch that replaces the ambient
transaction, and conditional commit share one admission path.
Deleted first:
- globals: InitializeGlobals, MaterializeMissingGlobals, the two-argument
constructor, the initializeGlobals plumbing in CultCacheMessagePack,
ContainsDurableRecord (cache and directory store)
- replication: the push-to-every-store loops and the attach-time push of
existing records
- typeof(T) as the schema owner in AddAsync/UpsertAsync and in
CultNetDatabase.PutAsync/PutPredictedAsync
- the ambient transaction: ExecuteTransactionAsync x2, CultCacheTransaction,
CommitTransaction, VisibleStoredDocuments, the AsyncLocal, the SemaphoreSlim
gate, and every ambient check
- CultCacheOpenOptions.PullOnOpen; OpenAsync is Task.FromResult(Create(...))
- DirectoryMessagePackBackingStore.ResolveLegacyUncataloguedRecordCatalog: the
catalog precommit (fe55bff) is an ancestor of the v4 page format (eea8248),
so no v4 manifest can reach it
- CultCache.DeleteAsync<T>; its one caller, CultNetDatabaseSubscriptionClient,
called it by reflection and now calls Remove(key)
Added:
- AddBackingStore(store, params Type[] homes): attach validates (clean, not
already attached, one untyped store, no claimed home type, no admitted
record changes home) and then pulls under the gate
- Home(type): most derived routed home, else the untyped store
- Admit: every add and remove, from a write, a batch or a load, validates
(home, read-only, loaded-from-home, global singleton), lands durably, then
applies and publishes; a pull hands its whole delta over in one call, so a
refused record leaves the store and the cache unchanged
- read-only stores (CacheBackingStore(readOnly), both store constructors,
CultCacheOpenOptions.ReadOnly); flush skips them and writes only dirty stores
- assignable GetGlobal<T>/GetByName<T>/GetByIndex<T>/Watch<T>; more than one
candidate throws naming them
- Commit(Action<CultCacheBatch>) returning bool, TryCommit returning
CultCommitOutcome, CultCacheBatch (Upsert, Remove, Expect, ExpectUnchanged,
sealed after commit), CultCommitRequest; CacheBackingStore.CommitBatch
evaluates conditions under the store's exclusive lock
- single-file store: <path>.lock sidecar for CommitBatch and PushAll; a clean
store commits onto the file as it is, so records it never loaded survive
- storedAt minted in one place and bumped a tick when not later than the record
it replaces
Consumer adjustments in this repo: Mesh streaming tests drop PullOnOpen; the
Studio bridge stops reflecting on it; BackingStoreTests' global test creates
its global explicitly and its transaction tests are rewritten against Commit
(the two that proved ambient hydration rules are deleted); the pre-Cut 2
refusal test expects the attach to throw.

Every /// line in GameCult.Caching and GameCult.Caching.MessagePack goes; they
restated member names. Three blocks that state a rule stay as // comments:
MaterializeMissingGlobals runs after hydration so persisted globals win,
ExecuteTransactionAsync commits durably before the cache and observers
advance, and CommitBatch implementations restore their staged view on
failure. Both projects add NoWarn CS1591, since GenerateDocumentationFile is
on in src/Directory.Build.props.

ConfigureCache, ConfigureStore, DirectoryStorePath, DirectoryStoreHydrationFilter
and ConfigureDirectoryStore had no consumer outside tests. CreateCore attaches
the directory store at its default record path, or the single-file store,
with no customization hooks. OpenAsync keeps its behavior (pull, then
materialize missing globals); PullOnOpen stays until Cut 3.
The indexed-filter test loses its selective-open half and keeps the v4
manifest assertions: the hot index carries only the SHA-256 page identity and
both records reload.
