The previous cut left two owners of publication: doors published and logged their
own change while a flow-scoped key mark told the Watch handler to skip it. A write
an observer made to the door key inside that scope was dropped, a door change and
its re-resolved variant were logged in the wrong order, and log state was
unlocked. Doors now register the context they alone know (wire message,
reconciled prediction, replicated entry) under the identity of the instance they
write or remove; the Watch handler consumes it once for that change and is the
sole publisher and logger. Only a shard primary mints log sequences; a replica
logs only the primary entries its replica door hands over. Log state sits under
one gate. The AsyncLocal mark and every door-side publish or append are deleted.

CultNetDatabase watched OnUpdate, which fires for loads alone, so cache.Commit,
cache.UpsertAsync, variant dependents re-resolved by a base edit and Flatten never
reached subscribers or the mutation log, and a load removal carried an empty key.
The database now observes cache.Watch, the one owner of admitted changes. A write
door of the database (PutAsync, DeleteAsync, ApplyPut/Delete, replica apply, sync)
marks the key it is committing and publishes that change itself, since it carries
the shard-log entry; every other change publishes from the cache, keyed.

S-9: CurrentAsOf() returned the maximum shard-log sequence across every
shard the database holds, but that sequence is a per-shard counter -
mixing shards' counters together could report a page as exact "as of" a
sequence a different, untouched shard advanced to while the page's own
shard sat still. CultNetDatabase gains CurrentAsOf(shardId), the watermark
of one shard's own log, and CultNetDocumentRegistry.SelectPage now scopes
asOf to the single shard EnsureSingleShard already resolves the matched
rows to, falling back to the caller-supplied value only when the selection
matches no rows.
S-11: CultNetDatabaseServer.HandleSubscribeV1Async refused a hop-bearing
selection before running the door (Validate), so a selection invalid for
an unrelated reason (an empty keys list, an undeclared index, ...) got a
hop refusal that had nothing to do with why it was actually rejected. The
door now runs first, unconditionally. The hop refusal also always named
the field "cites" even when the selection carried Cited instead; it now
names whichever hop is actually set.

CultNetDatabase already had a public ResolveShard(schemaId, key) wrapping
ResolveShardInternal; the previous commit added a second one with the same
signature. CultNetDatabaseServer.CreateSelectionResponse's shardIdOf callback
uses the pre-existing one.

R-O: CultNetSelectionCursorKey is a per-process (per-CultNetDatabase-instance) 32-byte
random key. CultNetSelectionCursor.ComputeDigest is now an HMAC-SHA256 under that key
instead of an unkeyed SHA-256, so a cursor cannot be forged without the key and does not
verify across a restart (a fresh CultNetDatabase mints a fresh key). The cursor body
(asOf/ordinal/schemaId/recordKey/digest) is length-prefixed (<byte length>:<value>, no
delimiter) instead of joined with a bare "\x01"-separated string, so a record key
carrying any character, U+241F included, round-trips. CultNetSelectionEvaluator.Select/
Page/ComputeDigest take an optional CultNetSelectionCursorKey, defaulting to a
process-wide key generated once so existing callers that never wire up a database still
get a keyed digest. CultNetDatabase gets a CursorKey property (random unless
CultNetDatabaseOptions.CursorKey is supplied) and passes it through
CultNetDatabaseServer.CreateSelectionResponse.
Rust already landed R-O (5aac120) under its own algorithm, deliberately not byte-matching
the reference: its own doc comment says a cursor is never handed across runtimes, so only
collision-freedom and keying are load-bearing, not the wire bytes. That is a real
divergence from this pass's instruction to match Rust's wire encoding exactly - reported
in full in the batch report.
R-Q: the two replica-apply paths (ApplyCommittedPutAsync, ApplyCommittedDelete) recorded
the mutation-log entry but never set _lastWriteSequence, so a row's order/cursor position
looked like "never written" until it was written again locally. Both now set it from the
entry's own sequence, matching AppendMutationLogEntry's local-commit path.
InitializeLogSequencesFromStore rebuilt only _nextLogSequences at startup; it now also
rebuilds _lastWriteSequence by replaying the durable log's Put/Delete entries in sequence
order. CultNetDatabase.ResolveShard is a new public wrapper over the existing shard
resolution; CultNetDocumentRegistry.SelectPage/CreateSelectionResponse take an optional
shardIdOf callback and refuse (reusing CultNetSelectionInvalidException/selection_invalid,
R-N) when a selection's matched rows resolve to more than one shard's log, because asOf is
a single watermark and is not exact for a shard-spanning page.
CultNetDatabaseServer.CreateSelectionResponse wires shardIdOf/cursorKey through from the
database.
Also fixes a defect the Rust Hands found while matching wire bytes:
CultNetErrorMessage.ForReferenceOutsideTarget double-prefixed "reference_outside_target: "
- the exception's own message already carries it. Now prefixed once, matching Rust's
ForReferenceOutsideTarget.

The first attempt at R-R built a CultNetSelection with an empty (non-null)
Keys/Schemas array straight from the lowered v0 filter and handed it to the
shared evaluator. CultNetSelectionValidation.ValidateShape refuses exactly
that shape ("selection.keys is present and empty"), because for the v1 typed
door an empty list is a caller mistake. v0 and v1 read the same emptiness
differently on purpose (v0: answer nothing; v1: refuse), so v0 must decide
its answer before the selection ever reaches Validate.
CultNetDocumentRegistry.CreateRawSnapshotResponse and
CultNetDatabase.CreateShardSnapshotResponse now short-circuit to an empty
document set when the lowered schemas or keys list is present-and-empty,
without constructing a CultNetSelection or calling into the evaluator at all.
Caught by the test added in the previous commit
(CultNetDocumentRegistry_RawSnapshot_ExplicitEmptyRecordKeys_AnswersEmpty),
which failed with CultNetSelectionInvalidException before this fix. Verified
on Yggdrasil: dotnet test tests/GameCult.Networking.Tests -c Release, all
green (217 passed, 2 skipped by design).

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.

_projectRecord (CultNetDatabaseSubscriptionServer.cs) reached no production
caller and ran after authorization with no wire consumer. Removed the field,
constructor parameter, and both call sites in Watch() and
CreateProjectedSnapshot(); projection is a value on a v1 selection now, not a
delegate. The two tests that used projectRecord to simulate a record's
identity changing for the reconcile diff
(DatabaseSubscriptionServer_AuthorizesRequestAndFiltersSnapshotAndLiveRecords,
…ReconcilesDeliveredProjectionAndBodyDemandWhenAuthorityChanges) are rewritten
to drive a real rename through the database (delete the old key, put the new
one) instead, so they still prove authorization filtering and the Reconcile()
diff/body-demand behavior.
Self's ruling (docs/cultnet-selection-cut.md, 2026-09-22): the fourth
schema-matching copy at CultNetDatabase.cs, serving CreateShardSnapshotResponse
and SchemaMatchesCatalogFilter (MatchesRequestedSchema + a duplicate
InferSchemaName), collapses into CultNetSchemaAliasMatching.MatchesAny, the one
matcher landed in commit 1.
Networking tests: 162/162 (was 162/162 after commit 1; no count change, two
tests rewritten not added). Negative grep: _projectRecord|projectRecord empty;
MatchesRequestedSchema gone (one remaining substring hit is
RawSnapshotPayloadMatchesSchema in CultMeshSnapshots.cs, the Mesh copy this
commit does not touch — collapses in the next commit).
Mesh collapse (§4/§11 of the map, ~365 gross lines across CultMesh.cs,
CultMeshSnapshots.cs, CultMeshClient.cs, CultMeshBodyDemand.cs) is not in this
commit; it is large enough to build on its own and follows as commit 2b.

docs/cultnet-selection-cut.md section 2/4/6/7/8: CultNetSelection (schemas,
keys, fields, cites, cited, projection, descending, limit, cursor) with its
door validation (S1), and CultNetSelectionEvaluator: the single-row Matches
fast path (D6) and the full Select (order, hop, cursor, paging). Neither
reflects over a document; both read only through the cache's public surface
(commit 0).
Three v1 messages beside v0 (cultnet.snapshot_request.v1,
cultnet.database_subscribe.v1, cultnet.snapshot_response_raw.v1), their
schema files under contracts/cultnet, registry entries and dispatch arms.
CultNetSchemaAliasMatching goes internal -> public (D4), the one alias
matcher. CultNetDatabase gains LastWriteSequence(schemaId, key), confirmed
at the one append site (AppendMutationLogEntry) that every committed write
takes a shard-log sequence, including a local PutAsync outside any shard.
Three engines deleted, one evaluator wired in their place:
- CultNetDocumentRegistry: CreateRawSnapshotResponse's reflection loop over
cache.AllEntries and MatchesRequestedSchema gone; cache.AllStoredDocuments
replaces the reflection entirely. v0 lowers into a Selection and walks the
evaluator's own pages so a v0 caller still sees its whole matching set
(D3: v0 has no engine of its own). CreateSelectionResponse/SelectPage/
ToRawRecord/CreateSnapshotRequestV1 added.
- CultNetDatabaseServer: CreateChangeMessage/CreateRawDocumentRecord/Matches/
MatchesSchema/InferSchemaName (122 lines) deleted; CreateSubscription lowers
v0 into a Selection and matches through the evaluator.
- CultNetDatabaseSubscriptionServer: CreateAuthorizedChange/CreateChange/
CreateChangeCore/ResolveWireSchemaId/MatchesRequestedSchema/CreateRawRecord
(92 lines) deleted, replaced by CreateMatchedRecord. _projectRecord and
CreateProjectedSnapshot's collapse are commit 2's, per the map's own
deletion line, and are untouched here.
Discrepancy found and fixed (not in the map): CultNetDocumentBinding can
carry a schema id different from its descriptor's own
(CultNetDocumentBinding.ForDocument's schemaId override), which the old
per-engine matchers checked and a descriptor-only evaluator cannot see by
design (it stays decoupled from CultNetDocumentRegistry). Fixed at the two
call sites and in CultNetDocumentRegistry.SelectPage by resolving the
binding's schema id into the effective selection before evaluation
(CultNetSchemaAliasMatching.WithBindingSchemaAlias,
CultNetDocumentRegistry.ExpandSchemaBindingAliases), not in the evaluator.
Found by DatabaseSubscription_FiltersLiveChangesByWireSchemaBinding timing
out; both call sites now pass.
Second discrepancy, reported not fixed: CultNetDatabase.cs:1707 has a fourth,
undocumented copy of schema-matching logic (MatchesRequestedSchema, private,
serving CreateShardSnapshotResponse), which the map's section 1 audit did not
name among "three separate selector engines". Left untouched this commit:
it is out of the map's explicit deletes list and touching it risks shard
snapshot behavior with no budgeted verification.
Verification: dotnet test tests/GameCult.Networking.Tests - 162 passed (150
existing + 12 new), 0 failed; the seven map-named tests all still pass, two
rewritten for the new signatures (CreateChangeMessage now takes
CultNetSelection; CreateChange/CreateAuthorizedChange collapsed into
CreateMatchedRecord, returning CultNetRawDocumentRecord? directly).
tests/GameCult.Mesh.Tests - 252 passed, 1 pre-existing skip, 0 failed (no
Mesh source touched this commit). tests/GameCult.Caching.Tests - unaffected
(188, unchanged from commit 0).
Negative greps: GetProperty|GetField|GetCustomAttribute in
GameCult.Networking - only against the generic `object change` dispatch
(CultNetDatabaseChange<T>) and CultRecordHandle<T> construction, pre-existing
and out of this cut's scope, never against a document's declared values.
_projectRecord survives in CultNetDatabaseSubscriptionServer.cs (expected,
commit 2). CultNetSchemaAliasMatching is the only schema matcher outside the
one reported discrepancy.
scripts/mutate-dotnet.ps1: the caching mutation runner generalized into a
shared dotnet/NUnit harness (Target/TestProject/Entries/ControlFilter),
replacing scripts/mutate-cultnet-selection-caching.ps1 with an entries file
of the same six mutations (re-verified: all six still KILL). It is now
generic to any NUnit project in this repo, not only this campaign's two
targets - a candidate to sit beside tools/eureka-mutations.ps1 as the
dotnet-side counterpart. Nine new networking entries (S3, S5 x2, S7 x2,
S16 x2, S18) all KILLED. Not yet mutation-run: S1, S2, S6, S23 (pinned by
tests, not by a committed mutant); S9-S15 (subscription reconcile lowering,
v0 no-engine-of-its-own); S17, S20 (pinned by tests only). S19/S21/S22 are
cache-layer, covered in commit 0.

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.

ExecuteTransactionAsync (both overloads), RequireTransactionsForAuthoritativeWrites,
EnsureAuthoritativeTransaction and the AfterCommit deferral had no consumer
outside CultNetDatabase_RequiredTransaction_DefersRawPutPublicationUntilCommit,
deleted with them. Writes publish immediately, as they already did outside a
transaction. The cache's own transaction machinery stays until Cut 3 replaces
