A variant needs its base beside it, so a single-record store can never hold one:
that overload's refusal could not fire. SlotNames no longer throws on a catalog
that repeats a slot.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
C#, TypeScript, Python, Rust and CultMesh refuse an unknown
cultcache.store.* header and a fifth record slot, naming the version or the
key and schemaId. The silent slot-skipping and C#'s ignored header are
deleted, and CultMesh's second record decoder is gone. Shared vectors are in
tests/vectors/document-variants-c0/. v1 stores stay byte-identical. At base,
the single-file commit's read-modify-write rewrote a v2 store as v1, which
lost data; it now refuses.
Soul passed it. Cross-runtime interop was run and passes. Three C#
Caching tests fail on Linux at both base and tip: they are Windows
share-mode tests (a FileShare.Read handle blocking delete/replace), which
cannot pass on Linux.

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.

Delete the trailing Skip loop in the record reader, the ?? v1 header default,
and the mesh reader's copy of the record decoder. The single-file store and
CultMesh single-file reads accept cultcache.store.v1 only. Persistence-format
and parity docs state the rule.

content-vectors.rs-written.json is written by cultnet-rs and is identical
to the reference's file. transport-planes.md and content-sessions.md name the
Rust runtime's content path as the explicit compatibility path on the session
the client already holds, lasting until an authenticated content connector
exists behind the same fetch_content owner; runtime-parity-scope.md gets the

What lands:
- Cut 3: the native MsQuic bridge, with the Windows release leg and F5
closed on both platforms, and the closerace fixture fix.
- Cut 4: the koffi Node binding, consumer, session manager and trust.
- Cut 5: the TS provider. It reaches the C# native connector, which is
the Unity overlay's path, on Windows.
- Fix batches 1-4: use-after-free, handler isolation, the
handshake-timer eviction, the koffi allocation leak, one C#-shaped
inbox, encode-once, advertisedHost, publish-only
(acceptClientFrames: false), and maxConnections.
- Retention: the provider seeds late joiners with the newest
latest-only frame per (channel, body), in TS and C#.
- Cut 6, narrowed: native binaries committed under
packages/cultmesh-ts/native, built by Actions. A second from-scratch
build reproduced them byte for byte.
Gates: four Opus Soul passes on the runtime and one Sonnet pass on the
packaging. The last runtime pass found that the connection death under
load was the old handshake eviction, which fix 3a had removed, and it
confirmed StreamPixels' load (60 Hz latest-only for 10 minutes) with
flat memory.
Also carried, per the operator's ruling: CultMath erf/erfinv (Cut 12.0
and its fix batch) from the branch base.
Map conflicts were resolved in favour of main, which owns the maps. The
only branch-side lines main lacked were a Cut 3 "still outstanding"
block that main's closure supersedes.
Open follow-ups, recorded on the map: IPv6-literal endpoints cannot be
dialled; consumer-side native queues are unbounded while Unity is not
polling; a client can see connect() resolve past maxConnections before
the refusal arrives; subtraction (about -130, mostly comments) is
deferred.

One sentence each in the C# QUIC README and the transport-planes doc: a
provider retains the newest latest-only frame per (channel, body) and
delivers it to a peer as soon as it attaches, bounded by the number of
distinct keys.

CultNetV0SelectionLowering.Lower collapsed a non-null-but-empty filter list to
null ("no filter"). That corrupted two pre-cut v0 behaviours the same
function feeds:
- CultNetDatabase.CreateShardSnapshotResponse and
CultNetDocumentRegistry.CreateRawSnapshotResponse (b3d9cf7) both test
`filter?.RecordKeys != null`, not a length, so `recordKeys: []` always
answered empty. Lowering the empty list to null made it answer every row
instead. This corrects the ruling from the commit-2 fix batch that lowered
an empty v0 list to "no filter".
- CultMesh.ResolveDefaultSelection used the same collapse to decide whether an
explicit empty recordKeys should still fall back to the document type's own
schema default; under the corrected Lower it must not.
Lower(null) still means "no filter"; Lower(non-null) is always a real
(possibly empty) array. The evaluator already treats a non-null empty Keys
array as "match nothing" (CultNetSelectionEvaluator.MatchesSchemaKeysFields);
only the v0 lowering was erasing that signal before selections reached it.
Also restores the pre-cut requested-key order for
CultNetDocumentRegistry.CreateRawSnapshotResponse: pre-cut, requested record
keys were iterated in the order the caller sent them (a HashSet<string> built
from the array, which enumerates in insertion order); the new shared
evaluator's constant ordinal fell back to schema-and-key sort order instead.
ordinalOf now ranks rows by their position in the requested key list when one
was given.
Rewrote CultMeshStreamingTests.FetchDocumentsAsync_WithExplicitEmptyRecordKeys
(renamed ...AnswersEmpty) to assert the corrected behaviour instead of the
ruling it used to pin. Added
CultNetDocumentRegistry_RawSnapshot_ExplicitEmptyRecordKeys_AnswersEmpty,
CultNetDocumentRegistry_RawSnapshot_KeepsRequestedRecordKeyOrder and
CultNetV0SelectionLowering_Lower_DistinguishesNullFromExplicitEmpty to
NetworkingTests.cs.
Not done in this commit: CultNetDatabase.CreateShardSnapshotResponse (the
shard-replication snapshot path) still orders by the evaluator's default
schema-and-key tiebreak. Its own pre-cut order was raw cache iteration order,
which the new evaluator has no equivalent for and shard replication does not
appear to depend on row order; flagged as a discrepancy rather than changed
without a test that would pin the "right" order. The side-by-side b3d9cf7 vs
HEAD comparison run the spec asks for was not executed in this pass; the
pre-cut behaviour above comes from reading CultNetDatabase.cs and
CultNetDocumentRegistry.cs at b3d9cf7 directly.

Wires v1 into both C# servers (R-A): CultNetDatabaseServer registers
CultNetSnapshotRequestV1Message/CultNetDatabaseSubscribeV1Message
listeners and Server.cs's pre-verification allowlist gains them;
CultNetDatabaseSubscriptionServer's subscribe path is generalised to a
shared SubscriptionRequest so v0 (lowered) and v1 selections run the
same Subscribe/Watch/Reconcile core, with D6's rule wired in: a
hop-bearing selection runs the full reconcile diff on every change
instead of the single-row fast path. CultNetDatabase.CurrentAsOf gives
both servers a real snapshot watermark.
Fixes the confirmed parity and correctness defects from Soul's
whole-cut pass:
- R-B: cited/cites edges are anchored to the row the direction actually
reports against (the citer under cites, the cited row under cited),
not filtered by "From is on the page" regardless of direction; order
is page-row order then (from, role, to) in code-point order.
- R-C: a new CultNetCodePointComparer replaces every StringComparer.Ordinal/
string.CompareOrdinal in the row tiebreak, cursor position and edge
order, so an astral key sorts the same way here as it does under
Rust's UTF-8 byte comparison.
- R-D: CultCache renders a float/double's exact decimal expansion from
its IEEE-754 bits via BigInteger (RenderExactFloat/RenderExactDouble),
never .NET's shortest round-trip form, which rounded a tie the
opposite way from Rust at some values. The now-dead ExpandScientificNotation
is deleted.
- R-E: MatchesCitation compares a cites target through
CultNetSchemaAliasMatching instead of an exact SchemaId string
compare; ToEdge and ToRawRecord now emit the same wire schema id
(WireSchemaId) for the same row, where ToEdge previously used the
descriptor's own id and ToRawRecord the binding's override.
- R-F: CultNetSelectionEvaluator.Select validates first, unconditionally
- the validate:false/true flag on SelectPage/CreateRawSnapshotResponse
is gone, so no public evaluation path can skip the door. Mesh's
EnsureV0Compatible runs the new CultNetSelectionValidation.ValidateShape
(the declaration-independent half of the door) before its own v0
transport refusals, so Keys=[]/[""] is refused there too.
- R-G: Evaluation.TotalMatched is the selection's whole matching count;
SelectPage's Matched field now reports it instead of the page's row
count. CreateRawSnapshotResponse and CreateShardSnapshotResponse
(v0/shard full walks) call the new CultNetDocumentRegistry.SelectAll,
which evaluates once via CultNetSelectionEvaluator.EvaluateAll and
projects every matched row, instead of looping SelectPage per 200-row
page and re-filtering/re-sorting the whole row set each time.
- R-H: the cursor digest is length-prefixed for every string and list
(AppendString/AppendList) instead of delimiter-joined, closing the
collision ["a|b"] == ["a","b"] and ["a,b"] == ["a","b"].
- R-J: any_of on a numeric alias compares TryGetIndexNumber's canonical
rendering, not the string getter's culture-dependent ToString().
- R-M: WithBindingSchemaAlias is deleted; both servers' single-change
fast path calls CultNetDocumentRegistry.ExpandSchemaBindingAliases
instead, the one binding-alias reconciler. The duplicated v0/shard
lower-and-page loop is gone with SelectAll above.

Soul found commit 2 didn't pass (docs/cultnet-selection-cut.md, 2026-09-22):
empty/blank schemas-keys still reached the evaluator, the shard snapshot ran
its own loop instead of the evaluator, Mesh's v0 wire silently dropped v1-only
selection terms, the Mesh one-pass read could return the wrong schema's
record at a shared key, two decode rules for a foreign schema id disagreed,
dead identity-comparison code from the _projectRecord removal was still live,
and a disposed-socket race could abort a mutation run instead of recording
NO VERDICT. This is Self's fix batch for all of it.
- CultNetSelection.Validate now refuses a blank/whitespace entry inside
schemas or keys, not just an empty array. CultNetSelectionEvaluator no
longer treats [] as "no filter" (the door already refuses it before
evaluation). CultNetV0SelectionLowering is the one place that lowers an
empty or all-blank v0 list to null; CreateRawSnapshotResponse and
CreateShardSnapshotResponse both route through it, and CultMesh's own
Clean() now delegates to it instead of duplicating the rule.
- CreateShardSnapshotResponse no longer carries a private loop or its own
schema/key matching: it builds a CultNetSelection and answers through
CultNetDocumentRegistry.SelectPage (the same evaluator path as the
non-shard snapshot), with the shard's own membership check as a row
filter. Binding-alias expansion now runs on both paths identically.
- ResolveDefaultSelection decides "no schema filter" from the cleaned
recordKeys, not the raw array length. OverlaySelection stops deciding what
a missing override means: any explicit schemaIds/recordKeys override
replaces the default selection wholesale; no override keeps the default
untouched.
- CultMeshSnapshotRequestOptions.Selection is now checked by
EnsureV0Compatible before every send: fields, cites, cited, limit, cursor,
descending, and any non-default projection are refused typed
(CultNetSelectionInvalidException), never silently dropped from the v0
wire message. Mesh sending v1 is FU-Mesh-v1, not this cut.
- CultMeshHotBodySubscription.Selection returns a defensive copy on every
read so its arrays can't be mutated out from under the stored selection.
- ReadDocumentFromSnapshotResponse now searches candidates at one recordKey
in one order - exact schema, then alias, then a foreign schema id decoded
from the payload - instead of one OR'd condition where a case-insensitive
or structurally-lucky candidate could win first. The foreign-id decode
reads the payload's embedded schema version with the registry's shared
CultNetDocumentRegistry.TryReadSchemaVersion and alias-matches it against
the caller's own descriptor directly, rather than resolving to "whichever
registered type owns this schema string" - that resolution is ambiguous
when two document types alias the same schema id (MeshNoteDocument and
MeshNoteAliasDocument in the existing fixtures), which is what broke on
the first pass; TryResolveDescriptorByPayloadSchema stays for its existing
caller (ResolveDescriptorForRawDocument) with a note on when not to use it.
DecodeSnapshotDocuments and the Mesh copy of the payload-schema decode
(RawSnapshotPayloadMatchesSchema/TryReadSchemaVersion) are deleted in
favour of the shared one.
- CultNetDatabaseSubscriptionServer: the dead RecordKey/SchemaId identity
comparisons in Reconcile and ApplyProjectedChange, and the duplicate-key
throw in CreateProjectedSnapshot, are deleted - they can no longer fire
now that a projection's dictionary key is always the record's own key.
A new test flips authorizeRecord per key while the whole request stays
authorized (so DemandActive never toggles) and proves both halves of the
remaining diff: the removal of a now-unauthorized key and the add loop
picking up a newly-authorized one.
- Every NetworkingTests.cs test that starts an IsBackground poll thread now
joins it before its server disposes (about 20 tests; one already did).
- scripts/mutate-dotnet.ps1: a dotnet-test-host crash writing to stderr no
longer throws the whole run away under PowerShell 5.1's
$ErrorActionPreference = 'Stop' (2>&1 on a native command wraps stderr in
a terminating NativeCommandError); Run-Tests catches it and the entry loop
records NO VERDICT instead of aborting every remaining entry.
- Two probe tests: CultNetDatabase_ShardAndNonShardSnapshot_Agree{On
UnfilteredRequest,OnBindingSchemaIdOverride} prove the shard and non-shard
snapshot paths agree, including shard-membership exclusion of a document
outside the shard's key prefix and a binding schema-id override matching
on both paths.
- Mutation entries updated/added to match: the stale NET-D4-FourthMatcher
entry (its anchor was the private loop this batch deleted, not refactored)
is replaced by NET-D4-ShardMembership-Revert; the Mesh entries file's
header miscount ("two of three" loosening entries when there are only
two) is corrected and both previously-surviving loosening mutants
(MESH-DEFAULT-Loosening, MESH-KEY-Loosening) now have killing fixtures;
scripts/mutate-cultnet-selection-fixbatch2.entries.ps1 is new, covering
Reconcile's remaining two mutants.

Collapses the rest of the Mesh selector surface named in docs/cultnet-selection-cut.md
section 4/11 onto CultNetSelection:
- CultMeshSnapshotRequestOptions becomes a record carrying Selection in place of
SchemaIds/RecordKeys; its three hand-written clone functions
(CloneSnapshotRequestOptions x2, CloneSnapshotFacadeRequestOptions) are gone in
favor of `with`.
- CultMeshPeerSnapshotDocumentOptions becomes a record for the same reason;
WithPublicationBindingOptions and ToSnapshotRequestOptions collapse to `with` and
one inlined Selection literal at their single call site.
- CleanSnapshotFilter and the three-times "no schema filter when keys are given"
rule collapse into two owners: CultMesh.ResolveDefaultSelection (the typed-document
default) and CultMesh.OverlaySelection (explicit override over defaults).
- CultMeshHotBodySubscription carries one Selection instead of parallel
RecordKeys/SchemaIds allowlists.
- ReadDocumentFromSnapshotResponse's four-tier fallback collapses to one
recordKey-anchored read: exact schema/alias match, or (foreign/runtime-generated
schema id) a payload that decodes as TDocument. The two tiers that matched by
schema alone or recordKey alone - the ones that could return a record under the
wrong key - are gone; DocumentHandle_ReadsRemotePeerSnapshotsAsTypedDocuments
pins the surviving recordKey-anchored decode fallback.
Two items in section 11's table are not cut here, by finding rather than oversight:
- IsSameCultDocumentSchema (CultMesh.cs) already delegates to the one
CultNetSchemaAliasMatching owner (no second engine); deleting the wrapper would
duplicate its type-to-descriptor resolution at four call sites instead of
collapsing it. Left in place.
- The selector literals in CultMeshClient.cs (574-604, 830-860, 932-962) call
CultNetDatabaseSubscriptionClient.SubscribeAsync, which stays a v0
(schemaIds/recordKeys) API in this cut - that client is not named in section 7's
per-file plan. There is no Selection to move these onto without adding a v1
subscribe path to Networking, which is out of this commit's scope. Left in place.
Tests: GameCult.Mesh.Tests 252/253 (1 pre-existing unrelated skip), 0 failed.
GameCult.Networking.Tests 161/161 excluding one pre-existing flaky test
(DatabaseSubscriptionServer_ReconcilesDeliveredProjectionAndBodyDemandWhenAuthorityChanges,
a background RUDP poll thread racing a disposed socket in code this commit does not
touch; it crashes the test host the same way on this branch before this commit too).
GameCult.Caching.Tests 188/188.
Net line count, src/GameCult.Mesh only: +143/-226, net -83. Section 11 estimated
about -326 for this cut's slice. The gap is mostly the two items above (about -49
of the estimate) plus one already-ruled keep this map's Progress block already
named (the foreign-schema-id decode fallback, -41 in the table, kept per the prior
Hands' ruling and untouched here) and the four-tier fallback surviving as a
two-tier one rather than a zero-fallback exact read (an honest test-enforced
requirement, not a padding choice).

CultMesh.IsSameCultDocumentSchema (CultMesh.cs) and the decode-time alias check
in CultMeshSnapshots.DecodeSnapshotDocuments both re-implemented schema-identity
comparison independently of CultNetSchemaAliasMatching, the one matcher landed
in commit 1. Both now call CultNetSchemaAliasMatching.Matches; the private
InferSchemaName duplicated at CultMeshSnapshots.cs is deleted (Matches already
applies the same .vN inference internally).
Spec discrepancy, reported per the Hands brief (map contradicted by the Body):
docs/cultnet-selection-cut.md section 4 lists CultMeshSnapshots.cs:1033-1047
(RawSnapshotPayloadMatchesSchema) and :1078-1088 (InferSchemaName) as deletions,
on the stated reasoning that decode no longer needs a client-side re-filter
because the server's v1 answer is exact. Deleting RawSnapshotPayloadMatchesSchema
outright breaks two existing, still-relevant Mesh tests:
SnapshotHelpers_DecodeSameSchemaAliasFromForeignSchemaId and
SnapshotEndpoint_SyncsCompatibleForeignSchemaIdIntoLocalCache
(CultMeshStreamingTests.cs). Both cover a wire schemaId this runtime cannot
resolve by any alias at all (a foreign/runtime-generated id, e.g.
"runtime.generated.mesh-note.ui.42") where the only way to decode is to trust
the payload's own embedded schemaVersion. That is a decode capability, not a
re-filter of an already-exact server answer, and the map's stated reason for
deleting it does not apply to it. Smallest change keeping the map's intent
true: kept RawSnapshotPayloadMatchesSchema and TryReadSchemaVersion, deleted
only the duplicate InferSchemaName inside it and routed the comparison through
CultNetSchemaAliasMatching.Matches.
Test counts, no regressions: Networking 162/162, Mesh 252/253 (the one
pre-existing skip), Caching 188/188.
Negative grep: MatchesRequestedSchema empty. The one remaining
"MatchesSchema(" grep hit is RawSnapshotPayloadMatchesSchema's own name and
declaration, kept for the reason above.
Still outstanding from the map's Mesh collapse (§4/§11, ~365 gross lines):
the five cloned CultMeshSnapshotRequestOptions-carrying option records, the
"no schema filter when keys are given" rule (x3), CleanSnapshotFilter, the
four-tier ReadDocumentFromSnapshotResponse fallback, and every selector
literal in CultMeshClient.cs/CultMeshBodyDemand.cs/CultMesh.cs peer-snapshot
and body-subscribe construction. Those require CultMeshSnapshotRequestOptions
(and the v0 wire builders that read it) to carry a Selection instead of
separate SchemaIds/RecordKeys — a wider, structural change across Mesh's
public surface that is not done in this commit. Recorded as the next slice.

CounterState in samples/eve-browser-network used string [Key]s, which the
registry rejects at registration, so the provider threw on open. Keys are now
0 counterId, 1 count, 2 receipts. The payload becomes a MessagePack array, so
the browser lowerer reads count positionally instead of by field name. The
getting-started chapter carried the same string-key shape and is corrected to
match.
BenchItem needed nothing: a5d1be6 already marked it [MessagePackObject]; the
earlier scan rejection came from a stale benchmark build. After rebuilding,
both types register.
No .cc stores exist under samples.

PlayerData, CultMeshSimulationFact, the Networking interop peer's
CultNetInteropNote, the cultnet-py benchmark item and the Caching test
documents lacked [MessagePackObject]. Only the generated codec could
serialize them; MessagePackSerializer refuses such types. Non-public test
documents take [MessagePackObject(AllowPrivate = true)], as consumer
internal documents already do, and ConditionalCommitTests.Slow marks its
private backing fields [IgnoreMember].
Same [Key]s, so payloads are unchanged: a pre/post probe over the
Networking assembly and both interop peers showed identical schema id,
content hash and payload bytes for all 9 documents, PlayerData equal once
its Guid.NewGuid() default id is masked.

The generator and CultDocumentRegistry now discover members by the same
steps: most-derived declaration first, override chain collapsed to one
member, attributes read up the override chain, rejections in one order
with one text (GCC001 / InvalidOperationException).
- Accessors are named per document, so documents sharing a [CultName] or
[CultIndex] base member no longer emit duplicate methods (CS0111).
- Duplicate [Key] slots are refused, including new-hidden fields and
properties; a hidden persisted member with a different slot is refused.
- String [Key("x")] gets its own message instead of "has no [Key]".
- A persisted property whose set accessor is private, protected or init,
or a readonly field, is refused instead of CS0272 in generated code.
- Overrides: MessagePack's DynamicObjectResolver reads the base
declaration's [Key]/[IgnoreMember] (it throws "key is duplicated" for a
re-keyed override and serializes an override marked [IgnoreMember]).
An override that changes them is refused in both paths; an override
that repeats or omits them is accepted and byte-pinned.
- Typed Serialize<T>/Deserialize<T> used static Options and skipped
generated codecs and declared resolvers; deleted. CultNetDocumentBinding
and CultMeshSnapshots route through the untyped path with their registry.
DocumentShapeSweepTests compiles each shape through the generator and
compares generated vs reflective schema id, catalog, name/index values
and payload against MessagePack's own bytes, or equal rejection text.

ObserveAsync, ReactiveAsync and RefreshAsync read a snapshot without a
Sequence, so an older change admitted before the read but delivered after it
overwrote the newer value.
CultCache.GetWithSequence(key) returns the document and the cache's Sequence,
read together under the gate. A cache-backed CultMesh handle passes it to its
mirrors; each mirror subscribes first, then adopts the sequenced read under its
own gate and takes that Sequence as applied, so a straggler at or below it
drops. RefreshAsync on both mirrors uses the same adoption path. Public Mesh
surface unchanged. The read is non-generic because the Mesh route needs the
untyped document for same-schema conversion.
Contract: only Watch/WatchRecord changes carry Sequence; OnUpdate-derived
CultNet streams have no ordering or stale protection; schema-alias handles and
removals are not stale-protected; the sequence constructor argument changed
CultCacheDocumentChange<T>'s binary signature.
Tests: ObserveAfterNewerSnapshotIgnoresStraggler and
RefreshIgnoresStragglerOlderThanSnapshot (observed and reactive cases) fail on
4562340; SequencedReadReflectsEveryChangeAtOrBelowItsSequence.

bcae483 made the cache a delivery scheduler (tickets, _deliveryGate turn
waits, per-thread delivery queues). It deadlocked inside CultLib: a load's
delivery reaching a CultNetDatabaseSubscriptionServer observer that needs
_lifecycleGate, while a subscribe's demand handler holding that gate writes
the cache and waits for the delivery's turn.
The cache now owns order as data. Every admitted change takes the next value
of a per-cache in-memory sequence under the gate, published as
CultCacheDocumentChange<T>.Sequence. Delivery is the 544c087/b653f68 rule:
each call publishes its own changes on its own thread after releasing the
gate; nothing waits on another call's delivery. Cross-thread delivery order is
not guaranteed.
Deleted: ticket counter, _delivered, _deliveryGate, Monitor.Wait turns,
per-thread delivery queues, per-ticket catch-all, and the save-order contract
text with its observer-must-not-block rule.
Consumer: a cache-backed CultMesh document handle hands its observed and
reactive mirrors each snapshot's Sequence; ApplyCanonicalSnapshot drops one
not newer than the last applied.
Tests: SequenceIncreasesInAdmissionOrder,
ObserverWritingTheSameCacheDoesNotWaitOnOtherDeliveries,
SubscriptionDemandHandlerWritingCacheDuringDeliveryDoesNotDeadlock,
WatchRecordIgnoresStaleSequence. The last three time out on bcae483.

Removes FlushBackingStore, both PrepareForReloadOrShutdown overloads,
PullBackingStoreRecordsAsync, TryGet<T>, TryGetByName, TryGetByIndex,
Resolve<T>, the cache and store Logger, and LastSuccessfulFlushAtUtc on the
cache and stores. GetStoredDocuments<T> folds into GetAll<T>.
The soft flag goes from FlushAllBackingStores, ExecuteTransactionAsync,
CommitBatch and PushAll. It stays on FlushAsync(bool) because
CultCacheStudioWindow reflects on that signature until Cut 6.
CultMesh.FlushAsync and CultNetLocal.FlushAsync keep their parameter and
stop forwarding it.
The store's EntryAdded/EntryUpdated/EntryDeleted subjects become
protected internal Loaded/Unloaded callbacks set by the cache at attach.
AddStoredDocumentInternal is synchronous, so the GetAwaiter().GetResult()
bridges on the store subscriptions and the global materializer are gone.
Tests: drop the LastSuccessfulFlushAtUtc asserts; OpenAsync and GetAll tests
read through Get/GetAll; the persisted-global test proves the durable global
loads without staging a default instead of going through selective hydration;
the lease-before-observers test observes through CultCache.Watch; the
PullSelected selective-hydration test is deleted.
