From e420410fe9cedb83365329e2799ae4da6b4a5985 Mon Sep 17 00:00:00 2001 From: Meta Vens Date: Tue, 22 Sep 2026 01:57:35 +0200 Subject: [PATCH 01/79] CultNet selection cut1, commit 0: the cache's public read surface docs/cultnet-selection-cut.md section 6/7/10: the reflection loop at CultNetDocumentRegistry.cs:325-342 exists only because nothing outside GameCult.Caching can read a declared index value, reference, or numeric member (Members/IndexAccessors are internal, no InternalsVisibleTo to Networking). This adds the one public door instead: CultDocumentMemberView, CultDocumentDescriptor.DeclaredMembers/TryGetIndexValue/TryGetIndexNumber/ ReferencesOf, and CultDocumentRegistry.ResolveTargetLeaves (D9, computed live against the registry, never cached or persisted). Two registration refusals land beside DiscoverMembers' existing DuplicateSlotMessage/HiddenMemberMessage: D10 renames the ArgumentException ToDictionary already threw for two differently-named members sharing one index alias into a rejection that names the schema, both members and the alias; D11 refuses a reference member whose CLR shape the cache cannot walk (many:false needs CultRecordRef, many:true needs IEnumerable> or IDictionary, V>) instead of silently answering it as unreadable later. GameCult.Networking is untouched; the evaluator that will read this surface does not exist yet (commit 1). Verification: dotnet test tests/GameCult.Caching.Tests - 188 passed (176 existing + 12 new), 0 failed. New tests: TryGetIndexValue/TryGetIndexNumber reading an inherited alias; ReferencesOf over a single/many-list/many-dictionary reference, including two dictionary entries with different payload bytes (S19); ResolveTargetLeaves against an abstract target with no [CultDocument] of its own (D9), including a leaf registered after an earlier descriptor was built; IsNumeric agreement for a nullable numeric and a decimal member (S22); the two new registration refusals, dynamically emitted so registry discovery by attribute scan cannot see the rejected shapes. scripts/mutate-cultnet-selection-caching.ps1: a dedicated dotnet/NUnit mutation runner (the shared tools/eureka-mutations.ps1 harness only speaks cargo; scripts/mutate-cultmesh.mjs is the QUIC campaign's file and this campaign does not edit it, per the map's section 10). Byte-exact restore verified by SHA-256, a sidecar for crash recovery, M0 no-op control, one anchor match required per entry. Six entries (D8/S22, D10, D11 - revert and loosening each) all KILLED; final restore verified green.

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) and CultRecordHandle 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.

charset=UTF-8 Content-Transfer-Encoding: 8bit _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.

charset=UTF-8 Content-Transfer-Encoding: 8bit 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.

Added NET-D4-FourthMatcher-Revert, pinned by CultNetDatabase_Creates_ShardSnapshotResponse_ForCompatibleSchemaAlias: killed. Every pre-existing entry in this file now carries its own File, so the whole file runs as one invocation against both CultNetSelectionEvaluator.cs and CultNetDatabase.cs (it previously assumed a single implicit target and would throw given two). Ran the combined file: 10/10 entries killed, M0 green, both targets restored byte-exact (verified by git status showing no diff on either .cs file after the run). A loosening mutant for the same site ('(requestedSchemaIds != null && requestedSchemaIds.Length == 0) ||', i.e. reject only an empty-but-non-null requested-schema list) was run by hand and SURVIVED: CultNetDatabase_Creates_ShardSnapshotResponse_ForCompatibleSchemaAlias puts exactly one document in the whole cache, so an over-permissive filter still returns the same single row. Recorded as a comment in the entries file per the brief ("report it, do not replace it with an easier mutant") rather than committed as a fake kill or swapped for an easier mutant. Fixing it needs a second document of a different schema in the shard's fixture; not added here.

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).

M0: green, 87 passed (CultMeshStreamingTests).

All restores byte-exact (working tree clean after the run). Both SURVIVED entries are recorded as fixture gaps, not swapped for easier mutants: no test in CultMeshStreamingTests.cs passes an explicit empty (non-null) recordKeys array, and none varies a record key's case, so nothing distinguishes MESH-DEFAULT-Loosening's `recordKeys != null` from the correct `recordKeys is { Count: > 0 }`, or MESH-KEY-Loosening's OrdinalIgnoreCase from the correct Ordinal comparison. MESH-FOREIGN has a revert entry only; no distinct, still-wrong "loosening" of "decode successfully as TDocument" was found that isn't already one of the other two entries.

New CultNetCanonicalNumber (CultNetSelection.cs) is the wire's canonical grammar and comparator: IsCanonical validates ^-?(0|[1-9][0-9]*)(\.[0-9]*[1-9])?$ and excludes "-0" (the regex alone matches it); Compare orders by sign, then the integer part's length, then its digits, then the fraction padded on the right to equal length - a pure string function, no double anywhere on the path. ValidateField refuses a non-canonical number at the door (selection_invalid) rather than normalising it. - CultNetSelectionEvaluator.CompareNumber now takes two canonical strings and switches on CultNetCanonicalNumber.Compare's sign instead of comparing doubles directly. - CultCache.cs: CultDocumentDescriptor.TryGetIndexNumber and PersistedMember.NumberOf render a member's exact canonical decimal instead of a double. An integer renders exact (no 2^53 limit); decimal strips trailing fractional zeros; float/double use .NET's shortest round-trip ToString(), rewritten out of exponent notation to positional digits (ExpandScientificNotation) before the shared CanonicalizeDecimalDigits strips zeros and collapses a negative-zero result to "0"; NaN and infinity render null (TryGetIndexNumber returns false, matching "matches no comparison"). - contracts/cultnet/cultnet.selection.schema.json: "number" is now a string with the canonical pattern (a defence-in-depth (?!-0$) lookahead beyond what the door enforces in code), not a JSON number. - Tests: CultNetCanonicalNumberTests (new) pins IsCanonical/Compare directly, including the door's five named non-canonical spellings, magnitude vs. lexicographic ordering, sign, integer-part length, and a long past 2^53 against its float64 rounding. CultNetSelectionEvaluatorTests gains ValidationRefusesNonCanonicalNumberSpellings (+1, 1.0, 01, 1e3, -0) and its existing Number literals become canonical strings. CultDocumentSelectionSurfaceTests gains a dedicated FixtureLeafNumbers fixture and four tests: the 2^53+1 long rendering exactly, a decimal's trailing zeros stripped, a double's exponent notation rewritten to positional digits (1e21, 1e-7), and NaN/Infinity answering false. Mutation entries (scripts/mutate-dotnet.ps1): four new Caching entries (integer-through-float64, decimal trailing zeros, exponent expansion, NaN/Infinity) and five new Networking entries (the door's regex, the door's explicit "-0" exclusion, the comparator's integer-length check, a lexicographic-whole-string mutant, and the comparator's sign check) - all KILLED. The two pre-existing S16 (le/ge boundary) entries had to be re-anchored: their Old text quoted CompareNumber's previous double-based `left <= right`/`left >= right` spelling, which no longer exists now that CompareNumber switches on Compare's int result: `cmp <= 0`/`cmp >= 0`. Verification: dotnet test - GameCult.Networking.Tests 192/192 (was 183 before these additions), GameCult.Caching.Tests 192/192 (was 188), GameCult.Mesh.Tests 252/253 (one pre-existing unrelated skip, unaffected by this commit - no Mesh source touched). Caching mutation run: 10/10 KILLED (6 pre-existing + 4 new), M0 and final both green. Networking mutation run: 15/15 KILLED (10 pre-existing + 5 new, across CultNetSelectionEvaluator.cs, CultNetDatabase.cs and CultNetSelection.cs), M0 and final both green.

SelectionOperator mirrors CultNetSelectionOperator for evaluator ergonomics; FieldPredicate.op stays a raw wire string, never a serde-tagged union. - canonical_number module (Q-J, section 2 "Numbers"): is_canonical (a hand-rolled digit-grammar parser, no regex dependency added), canonicalize_decimal_digits, expand_scientific_notation, compare (sign, then integer length, then digits, then padded fraction - no f64 anywhere), and render_i64/render_u64/render_f64/render_f32 for a Row implementer's own rendering. probe_f64_display_never_uses_exponent_notation empirically verifies the map's claim about Rust's f64 Display (confirmed true) rather than trusting it. - Row/RowSet traits (D7): schema_id, record_key, ordinal, values, number (canonical string, never f64), references for Row; all_schema_ids, declared_indexes, declared_roles, is_numeric, target_leaves for RowSet. A blanket `impl Row for &T` lets sorted/filtered slices of references satisfy generic bounds without an extra copy. - validate (S1 door refusals), matches (D6 single-row fast path, hop-bearing selections assert via debug_assert since Rust has no exception type to mirror C#'s InvalidOperationException), select (order/hop/cursor/paging, D9's reference_outside_target refusal, S23's per-row match - never through a unique-index map, because there is none here to begin with). - Cursor: mint/parse/digest is this runtime's own internal algorithm (a cursor is opaque and never crosses runtimes - each server answers its own pages), not a byte-for-byte port of the reference's; what must match is the *rule* (asOf + last position + a digest bound to the selection), which it does, pinned by RS-CursorStale-Revert/Loosening and RS-CursorDigest-Revert. - contracts.rs: three v1 CultNetMessage variants (SnapshotRequestV1, DatabaseSubscribeV1, SnapshotResponseRawV1) matching the C# messages' field-for-field shape. SnapshotResponseRawV1 carries binary payloads (documents[].payload, edges[].payload), so it is routed through the existing raw JSON-bypass path (parse_raw_cultnet_schema_message/ encode_raw_cultnet_schema_message) alongside v0's DocumentPutRaw/ SnapshotResponseRaw, with its own require_*/encode_* helpers for SelectionDocumentRecord, RawDocumentHeader, Edge and RecordRef. SnapshotRequestV1/DatabaseSubscribeV1 carry no binary and use the ordinary serde_json-intermediate path. No message-layer selection semantics validation here, matching the reference (CultNetSchemaMessageSerialization.cs only deserializes; a server calls selection::validate against its own RowSet before evaluating). - snapshot_query.rs (D3/D4): serve_read_only_raw_snapshot's two hand-rolled allowlist filters collapse into one call to selection::matches over a lowered v0 Selection, through a minimal RawSnapshotRow wrapper whose ordinal/values/number/references are unreachable (the lowered selection never sets fields/cites/cited, so matches_schema_keys_fields never calls them) - documented, not hidden. Ruling (Self, 2026-09-22, docs/cultnet-selection-cut.md commit 2 fix batch, mirrored here per the coordinator's mid-task instruction rather than C#'s pre-fix spelling as it stood at e5348d3): - validate refuses an empty-but-present schemas/keys list (already had this) and now also refuses any individual entry that is empty or whitespace (fields[i]-style names: schemas[i]/keys[i]). - The evaluator never sees []; matches_schema_keys_fields does not special-case an empty list as "no filter" (it never did here - that C# fallback, CultNetSelectionEvaluator.cs:84 pre-fix, was never mirrored into Rust). - snapshot_query.rs's v0 lowering gets its own cleaning, owned by the lowering and not the evaluator: lower_v0_list turns an empty or all-blank v0 schemaIds/recordKeys list into None before it ever reaches validate or select. Tests: cultnet-rs 173 passed, 0 failed (was 111 baseline #[test]s pre-cut; +62 across lib unit tests, tests/selection.rs and tests/cultnet.rs). cultcache-rs unmodified, 64 passed, 0 failed (untouched by this commit - confirmed unaffected). GameCult.Networking.Tests (the new SelectionParityVectorTests.cs file, compiled but not yet fully exercised - see below) builds clean. Mutation harness (tools/eureka-mutations.ps1, scripts/mutate-cultnet- selection-rust.entries.ps1): 22 entries against src/selection.rs and src/snapshot_query.rs, all KILLED, M0 green. Covers: S1's empty-list and new blank-entry refusals (schemas and keys, revert x4), order/descending (revert), cursor staleness (revert + loosening) and digest (revert), S7's incoming negation (revert + loosening), S16's le/ge boundaries (revert x2), S18's reference_outside_target (revert), Q-J's door regex and -0 exclusion (revert x2), Q-J's comparator integer-length and sign (revert x2), Q-J's integer-through-float64 renderer, decimal trailing-zero stripping and exponent expansion (revert x3, the last two pinned via direct canonical_number unit tests since render_f64 itself cannot reach exponent notation given Rust's Display contract - verified, not assumed), and the new v0-lowering rule (revert). Negative grep: `rg -n "untagged" packages/cultnet-rs/src packages/cultcache-rs/src` empty. Not included here, landing as commit 4 once ready: the committed parity vector files (contracts/cultnet/interop/selection-vectors.{cs,rs}-written.json). Both directions already work for six evaluated selections and the [] door-refusal case; the blank-key-entry refusal vector cannot be generated from the C# side yet because the parallel C# fix batch implementing that door check (docs/cultnet-selection-cut.md, "Self's rulings...for the commit 2 fix batch") has not landed on this branch as of this commit. Rust's own tests (validation_refuses_a_blank_entry_in_schemas_or_keys, serve_read_only_raw_snapshot_lowers_an_empty_or_blank_v0_schema_list_to_no_filter) already pin both new rules independently of C#. Structural delta: packages/cultnet-rs/src/selection.rs +1407 (new), contracts.rs +616/-21, snapshot_query.rs +76/-21 (net +55, collapsing the fifth selector engine into one call), lib.rs +2, tests/cultnet.rs +67 (new v0-lowering test), tests/selection.rs +900 (new, evaluator tests + vector machinery), scripts/mutate-cultnet-selection-rust.entries.ps1 +233 (new), tests/GameCult.Networking.Tests/SelectionParityVectorTests.cs +296 (new). Against section 14's ~430-line estimate for selection.rs+contracts.rs: the two together land at ~2000 lines added, well over estimate - the map's own §14 correction already flagged commits 0/1 running roughly 2x estimate for the same reason (the hop's incoming index, the cursor, and per-field door messages cost more than the prose assumed), and the v1 raw-message handling (SelectionDocumentRecord/RawDocumentHeader/Edge require_*/encode_* helpers, ~400 lines) was not separately budgeted at all.

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.

One test (test_python_interop_peer_refuses_v1_selection_messages) proves a snapshot_request.v1 and a database_subscribe.v1 message both get the refusal, not an empty list. - packages/cultmesh-py/src/cultmesh_py/server.py's delegating path (_handle_connection_message -> handle_message) already refused every unsupported schema version generically, v1 included - no code change needed there. test_cultmesh_local_server_returns_errors_for_bad_requests gains an explicit assertion for a snapshot_request.v1 message through that same path, so the coverage is named rather than only implied by the generic case. This is the one exception to "do not touch packages/" in this fix batch: only these two Python packages' interop/server files and their tests.

A new test (serve_read_only_raw_snapshot_lowers_an_empty_or_blank_v0_schema_list_to_no_filter, extended) pins the dedup case directly. - Two mutation entries (RS-EmptySchemas-Revert, RS-EmptyKeys-Revert) added for the door's original empty-list refusal, which had tests but no mutation coverage before this commit. **S12: the two-way parity vectors**, contracts/cultnet/interop/selection-vectors.{cs,rs}-written.json, eight vectors each: the six evaluated selections from commit 3 (any_of+ge conjunction, descending+limit, gt boundary, cited exists true/false, three rows sharing one index value) plus two door-refusal vectors added for this ruling - `refuses_empty_schemas_list` (schemas: []) and `refuses_blank_key_entry` (keys: ["a-eq", " "]) - which decode their selection bytes and assert `validate`/`Validate` refuses at exactly the named field, never evaluating. The blank-key vector could not be generated before this commit: the door rule it exercises did not exist in the reference until 568e8e3 landed. `cites`-based hop vectors are deliberately absent (documented in both test files): MatchesCitation compares Citation.Target.SchemaId against the reference's real SHA-256 schema id exactly, with no SchemaName fallback, and this fixture pair has no way to agree on that hash across runtimes; `cited` (role/existence, matched by record key alone) is the hop direction both sides can cross-check, so incoming_exists_true/incoming_negation carry that coverage instead. Both reader tests pass: SelectionVectorsWrittenByRustDecodeAndEvaluateIdenticallyInTheReference (C#) and selection_vectors_written_by_the_reference_decode_and_evaluate_identically_in_rust (Rust), each judging the other runtime's file. **The remaining mutation matrix.** Of the coordinator's named set (S1, S2, S6, S9-S15, S17, S20, S23): S1 was already covered (RS-EmptySchemas/Keys, RS-BlankSchema/Key); S2 (any_of matches membership, RS-S2-Revert) and S6 (cites.role filters the hop, RS-S6-Revert) are newly covered - S6 needed a new fixture (cites_role_excludes_a_second_reference_at_the_same_target) because base_rows()'s citer-1 only ever carries one reference, so a mutant dropping the role filter had nothing else to wrongly match and survived against the original hops_one_edge_by_declared_role test; that finding is recorded in-line as a comment, not silently swapped for an easier mutant. S9-S15 (subscription reconcile, v0-lowering-of-subscribe) do not apply: D7 - no Rust caller subscribes in this cut, so there is no subscription client to mutate. S17 (inherited alias reaches every leaf) does not apply either: Rust's toy Row/RowSet has no inheritance to begin with - both leaves in the fixture declare "mass" independently, which is the Rust spelling of the same guarantee, already exercised throughout the suite without a dedicated mutant (there is no shared base-type discovery path to revert). S20 (edges only for a hopping selection) was investigated and found structurally vacuous in Rust as built: `edges` is only ever populated inside the cites/cited branches, so a mutant on the has_hop() gate cannot produce a different observable result for a non-hopping selection - no entry added; a real gap would need the evaluator's structure to change first. S23 (matches every row sharing an index value, never a cache's unique-index winner) has no revertable bug surface: Rust's Row/RowSet never had a unique-index map to begin with (D7), so this is pinned by construction, not by a mutation-testable rule; matches_every_row_sharing_an_index_value still exists as a positive test naming it. **A pre-existing, unrelated flaky test, found and worked around, not fixed.** tests/cultnet.rs's reactive_document_coalesces_direct_same_schema_alias_member_writes fails consistently when the mutation harness runs the full tests/cultnet.rs binary (both default-parallel and RUST_TEST_THREADS=1), but passes 5/5 in isolation and passes in a plain `cargo test -p cultnet-rs` run - state pollution from another test in that binary under the harness's specific invocation path, not a race this campaign's code participates in (nothing here touches reactive_document machinery). RS-V0Lowering-Revert's Command is narrowed to `cargo test --test cultnet serve_read_only_raw_snapshot` (filtering both M0 and the entry's own run to this campaign's test) so the suite does not depend on that unrelated test's health; the flake itself is reported here as a finding, not patched. Tests: cultnet-rs 174 passed, 0 failed (default parallel run). GameCult.Networking.Tests 196 passed, 1 skipped (WriteSelectionVectors, env-gated), 0 failed. Mutation harness: 24 entries (was 22 in commit 3; +RS-S2-Revert, +RS-S6-Revert; RS-BlankSchema/BlankKey and RS-V0Lowering-Revert's anchors and field-name assertions updated to match the landed fix batch's exact spelling), all KILLED, M0 green.

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.

Fixing ToEdge's mutant coverage surfaced a real bug the new tests caught: it serialized an edge payload through CultDocumentMessagePackSerialization, which requires the payload's type to be a registered CultDocument and throws for a plain declared value type (float, in the fixture); it now serializes directly through MessagePackSerializer. - R-D: CultNetCanonicalNumberTests gains "5\n"/"5\r\n" cases - .NET's $ matches immediately before a single trailing newline even without RegexOptions.Multiline, so the door's pattern is re-anchored with \A/\z and would have accepted "5\n" as canonical without this. Caching's TryGetIndexNumberRewritesADoublesExponentNotationToPositionalDigits is updated for 1e-7's actual exact decimal expansion (the R-D commit's own effect): the old assertion pinned "0.0000001", the shortest round-trip form a pre-R-D render would have produced. - R-K: every serverThread.Join() in NetworkingTests.cs that sat outside a try/finally now sits inside one, so a failed assertion cannot leave the poll thread running past the point where `using` disposes the socket it polls (an ObjectDisposedException on that raw background Thread was a host crash, not a test failure). The bodyDemand.HasConsumers assertions wait on the condition instead of assuming SubscribeAsync's completion and PublishDemand happened in an order a network round trip does not guarantee. - Reflection fix: DatabaseSubscription_FiltersCanonicalWireChangesByRequestedSchemaAlias built a v0-shaped CultNetDatabaseSubscribeMessage to invoke CreateMatchedRecord by reflection; that method now takes the shared SubscriptionRequest (R-A), so the test builds one through the same reflection path instead.

limit documents that it is clamped 1..=200 by the answering server rather than refused outside that range. - cultnet_py/interop_peer.py: handle_server_message refused only an exact ".v1" suffix, so a v2+ selection message fell through to a silent empty-list answer instead of a loud refusal. is_unsupported_cultnet_version matches any cultnet.*.vN with N > 0 instead. test_cultnet.py's R-2 test now covers v2 and v10, not only v1. - mutate-dotnet.ps1: an entry's File (from -Entries, often written with "/") is looked up against the $targets dictionary keyed by -Target's own spelling; a "\\" vs "/" mismatch didn't throw at the lookup - $targets[$file] silently returned $null - so the crash surfaced one call later as a null-argument error inside a .NET path API instead of as "unknown target". Both -Target and every File read from an entry now normalise through Normalize-TargetPath before indexing $targets. Discrepancy: the ruling names "both R-2 sites" for the Python fix; only one site with this exact narrow-match bug exists in packages/cultnet-py and packages/cultmesh-py (cultmesh_py/server.py's handle_message already refuses every unrecognised schemaVersion, v1+ included, through its own default branch). Fixed the one that exists; did not invent a second.

Known-expected failure: SelectionVectorsWrittenByRustDecodeAndEvaluateIdenticallyInTheReference fails against the currently-committed selection-vectors.rs-written.json (incoming_exists_true's edge count) because that file predates R-B and was not touched here - the parallel Rust Hands owns it.

Before this, both hop kinds keyed off From, so a cited selection's edges were silently empty unless the citer also happened to be on the page (Soul's F2). build_incoming_index iterates the caller's own row slice, never a HashMap, for its own order. - R-C: code-point order was already Rust's default str::cmp (UTF-8 byte order); no change needed there. - R-D: canonical_number::render_f32/render_f64 render the exact IEEE-754 decimal expansion from mantissa and exponent, via a small fixed-point bignum (~60 lines), replacing the previous shortest-round-trip-form path that rounded ties differently from .NET. expand_scientific_notation and its test are gone (R-M); the Display probe test is kept per the map. - R-E: schema_alias (ported from CultNetSchemaAliasMatching's string overload) is the one schema-identity rule for `schemas` and `cites.target.schemaId`; an unmatched cites target is refused at the door. Found and fixed along the way: matches_schema_keys_fields must not use schema_alias::matches_any's own "empty candidates matches everything" shortcut (correct for the door/reachability call sites it mirrors from C#) - v0's snapshot server calls matches() directly, without validate(), so an empty-but-present schemas list must still match nothing there too. - R-F: select() validates first and returns the typed refusal; matches()'s hop guard is a real assert!, not a debug_assert! a release build would compile out. - R-G/P-1: Evaluation and SelectionPage both carry matched, the total match count, not the page count. - R-H: Cursor::compute_digest is length-prefixed for every string and list, closing the collision Soul found (["a|b"] and ["a","b"] used to digest the same). - R-I: select_page projects a selection into the wire's SelectionPage - headers or documents under Selection::projection, matched, and edges; a header projection carries no payload, in edges too (S20). Test fixture: real SHA-256-shaped schema ids (sha256:.v1) replace the old fixture's schema names doubling as ids, which had silently masked the R-E gap (vectors passed only because "leaf_a" happened to already be both the alias and the id). Two documented discrepancies against the map's own worked numbers, both verified independently outside this crate (Rust bit decomposition plus a Node/BigInt cross-check): an f32 of 3e20 is 300000006012263202816, not the map's 300000002010536247296; 1e-7 as f64 is its own 79-digit exact expansion, not "0.0000001" (a stale shortest-form assertion this fix batch did not originally touch).

Proven both ways by tests/selection.rs's snapshot_response_raw_v1_round_trips_* tests, which round-trip real headers, documents-with-payload, and edges with and without a payload through the real cultnet.snapshot_response_raw.v1 message envelope. - snapshot_query.rs: deletes reject_duplicates and its two call sites - dead, because lower_v0_list already dedups (via its own HashSet) before reject_duplicates ever runs, so its duplicate check can never fire. (RawDocumentHeader::from_document, the Eq derives on the selection wire types, and two dead branches the mutation harness's own first run proved - exact_decimal_from_mantissa's redundant "if mantissa == 0" guard and big_mul_small's unreachable multi-digit carry loop - are selection.rs changes already covered by the prior commit in this batch.)

"New = if true" is the safe direction (a negative exponent's "for _ in 0..exponent" is just an empty range, not a cast) and is pinned against a negative-exponent test instead. - RS-V0Lowering-Revert (pre-existing, not from this batch) unexpectedly survived the first run: matches_schema_keys_fields's move to schema_alias::matches_any (R-E) picked up that helper's own "empty candidates matches everything" shortcut, masking the v0-lowering mutation this entry exists to catch. Fixed in the prior commit (matches_schema_keys_fields no longer uses matches_any's shortcut); a new entry, RS-E-EmptySchemasNeverMatchesEverything-Revert, pins the fix directly rather than only through v0's own lowering. All commands are narrowed with "-- --skip selection_vectors_written_by_the_reference_decode_and_evaluate_identically_in_rust": that vector-file test is legitimately pending the parallel C# Hands's own regenerated cs-written.json (this suite does not touch that file), the same carve-out this file already gave the pre-existing reactive_document_coalesces_direct_same_schema_alias_member_writes flake. Full run against this batch's final state: 36/36 entries killed, M0 green on both commands, no survivors.

Adds contracts/cultnet/interop/selection-vectors.fixture.json: the one row set both writers now build from, keyed by each schema's real SHA-256 content-hash id exactly as CultDocumentRegistry computes it (dumped via a temporary DumpFixtureSchemaIds run). Carries the rows either runtime needs - astral/BMP-private-use keys, a float tie, cites/cited, a cites target reached by alias - plus two DIFFERENT alias forms, because the two runtimes' alias matchers key off different descriptor attributes and no single candidate resolves through both (see the fixture's "//aliases" note and the report). Rewrites SelectionParityVectorTests.cs to load the fixture instead of hand-building rows (BuildFixture/BuildExtendedFixture deleted), assert the fixture's declared schema ids still match what the registry computes (fails loudly on drift instead of silently comparing wrong ids), and use the real schema id (not SchemaName) as a row's cross-runtime identity. Also fixes a real bug this file carried since before the shared fixture: both the writer and the reader compared `evaluation.Rows.Count` (the page size) against "matched" instead of `evaluation.TotalMatched` (the total, per R-G) - selections with a Limit were writing/checking the wrong number. The reader now collects every vector's mismatch instead of stopping at the first one, so a real parity defect is reported in full. Regenerates selection-vectors.cs-written.json from the shared fixture.

Replaces the invented fake sha256-shaped LEAF_A/LEAF_B/CITER/LEAF_A_ALIAS consts with lazily-loaded values read from contracts/cultnet/interop/selection-vectors.fixture.json (a std::sync::OnceLock-backed loader; FixtureRowSet's declared_indexes/ declared_roles/is_numeric/target_leaves become runtime string comparisons instead of const match patterns). NARROW_CITER stays a local, unshared id - it never appears in a cross-runtime vector. base_rows() keeps S2-S23's original 7-row set (now sourced from the fixture's first 7 rows, unchanged in value or order, so every test that enumerates it - orders_by_ordinal_then_identity_and_reverses, pages_exactly_once_and_refuses_a_stale_or_mismatched_cursor, matched_is_the_total_count_not_the_page_count, ... - still holds unchanged). A new all_fixture_rows() carries all ten rows (the fix-batch float-tie and astral/BMP rows too) for the two parity-vector functions only. write_selection_vectors_for_the_reference gains float_tie_exact_ge, astral_key_code_point_order, and the fixture's hash alias (leaf_a_hash_alias(), a synthetic ".v1" this crate's own schema_alias resolves) and name alias (leaf_a_name_alias(), "leaf_a.v9" - the form only CultNetSchemaAliasMatching's descriptor overload resolves) probes, mirroring the C# side. selection_vectors_written_by_the_ reference_decode_and_evaluate_identically_in_rust no longer panics on the first disagreement (evaluate_vector now returns a Result instead of .expect()'ing); it collects every vector's mismatch and fails once with the full list, matching the C# reader's same change. Regenerates selection-vectors.rs-written.json from the shared fixture.

C#'s production call sites (CultNetSelection.cs:438, CultNetSelectionEvaluator.cs:88,340) all use the descriptor overload of CultNetSchemaAliasMatching.Matches, never the bare id-vs-id overload. - Row gains schema_name() (defaults to schema_id() for rows with no separate name, e.g. raw wire records); RowSet gains schema_name(schema_id) -> Option. Both stand in for CultDocumentDescriptor.SchemaName, which this crate has no type for (D7). - schema_alias::matches/matches_any now take (candidate, schema_id, schema_name) and resolve a candidate's inferred name against the declared name, exactly as the C# descriptor overload does - not against schema_id's own inferred name, which is what the deleted hash-stripping matcher did. - Every call site (reachable_schemas, the cites.target door check, matches_schema_keys_fields's D6 fast path, matches_citation) now resolves and passes a schema's name instead of comparing two schema-id strings. - Deleted: the hash-stripping schema_alias::matches(candidate, schema_id) two-string overload. A hash-shaped alias (".v1") is not a wire form either runtime's production rule ever resolves. Behaviour verified against a standalone run of the exact C# algorithm (CultNetSchemaAliasMatching, CultNetDatabase.cs:47-97) covering exact-id match, bare-name match, .vN alias resolution, MatchesAny's empty-matches-all convention, ordinal case sensitivity, ".v" with no trailing digits, and multiple ".v" markers (last one wins) - every case is now a Rust unit test in schema_alias::tests. Test fixture (tests/selection.rs) updated: the fixture's hashAlias entries are now a shared negative check (neither runtime resolves them), and the nameAlias entries now resolve in Rust too, fixing the confirmed cross-runtime defect (schemas_by_name_alias). Regenerated contracts/cultnet/interop/selection-vectors.rs-written.json (15 -> 16 vectors): added refuses_cites_target_by_hash_shaped_alias, renamed hop_by_role_cites_hash_alias to hop_by_role_cites_name_alias. cultnet-rs: cargo test 223/223. C# reader (rs-written.json): 14/16 - the two failures are both the pending unmatched-cites.target door refusal (CultNetSelection.cs:361-391 has no such check yet), not a Rust defect; the other Hands' C# door fix covers both.

New entries for this cut's rule, per spec: - RS-E-Alias-RevertToHashStripping: the revert - go back to hash stripping (compare schema_id against schema_id's own inferred name, the deleted matcher's behaviour). - RS-E-Alias-CaseInsensitive-Loosening: the loosening - compare case-insensitively instead of Ordinal. - RS-E-Alias-AcceptAnyVersionSuffix-Loosening: a second loosening - accept any ".vN" suffix without comparing the name. - RS-E-InferSchemaName-StripAnyLastDotSuffix-Loosening: a function-of-input mutant - infer_schema_name strips any suffix after the last dot, not only a ".v" marker. Also fixed the invocation: File/Command values are relative to the CultLib repo root and carry --manifest-path packages/cultnet-rs/Cargo.toml (there is no repo-root Cargo.toml/workspace), matching -Repo C:\wal and -Target 'packages/cultnet-rs/src/selection.rs,packages/cultnet-rs/src/snapshot_query.rs'. Verified: M0 green (4 commands, 36+81+7+1 tests), all 40 entries killed by their own test, every restore byte-exact (git diff clean against the committed source after the run).

Resolved through CultNetSchemaAliasMatching, the reference rule, against every declared schema - not only the selection's own Schemas-filtered reachable set, which a second entry (NET-RE-DoorTargetReachableOnly-Loosening) proves: a cites target is a separate structural reference, not itself constrained by Schemas. Coordinator-assigned item; the shared parity fixture's refuses_unmatched_cites_target_schema vector (Rust side, another Hands) is not yet in selection-vectors.rs-written.json, so SelectionParityVectorTests.SelectionVectorsWrittenByRustDecodeAndEvaluateIdenticallyInTheReference does not yet exercise it - it will once that vector lands, unmodified by this commit. - NetworkingTests.cs gains CultNetDatabaseServer_AnswersV1SnapshotRequestRespectingItsFields (R-A's loosening) and DatabaseSubscriptionServer_SubscribesV1AndReconcilesAHopBearingSelectionWhenTheCiterChanges (S9 / R-A's subscribe-listener revert). Discrepancy: R-A's snapshot-request v1 listener registration (CultNetDatabaseServer's _server.OnCultNet(_snapshotHandlerV1)) has no mutation entry. CultNetDatabaseServer pairs only with Server (the LiteNetLib/TCP-secured production construction site), and no existing test in this suite - before or after this pass - drives Server's real client/listener dispatch for CultNetDatabaseServer; every test calls CreateSelectionResponse/CreateSnapshotResponse directly. That revert is recorded as not yet reached in the entries file, not swapped for an easier mutant.

Replaces the exponent-expansion entry with CACHE-RD-ExactExpansion-Revert (reverts to .NET's shortest round-trip ToString(), the exact defect R-D fixes) and CACHE-RD-FractionSplit-Loosening (an off-by-one digit-split bug that still looks "exact"), and re-anchors the NaN/Infinity entry on the current RenderExactDouble call. - Repairs one stale mutation entry in scripts/mutate-cultnet-selection-mesh.entries.ps1 (MESH-FOREIGN-Revert): anchored on the pre-R-L inline TryReadSchemaVersion call, which R-L's commit (c01bc0a) replaced with CultNetDocumentRegistry.PayloadMatchesSchema. Re-anchors it and adds MESH-RF-Door-Revert (R-F: EnsureV0Compatible runs CultNetSelectionValidation.ValidateShape before its own v0 transport refusals), with a new tests/GameCult.Mesh.Tests/CultMeshSnapshotOptionsTests.cs proving FetchSnapshotAsync refuses Keys=[]/[""] before ever touching a client. - All entries verified: Caching 11/11 killed, Mesh 7/7 killed (pending final confirmation on this run), restores byte-exact. R-L (docs/cultnet-selection-cut.md): the Python refusal of vN>0 already has a real regression test (packages/cultnet-py/tests/test_cultnet.py:1958-1978, unsupported_schema_version) but no mutation entry - mutate-dotnet.ps1 is a dotnet/NUnit harness only and this repo has no Python mutation harness. R-L's C#-adjacent piece (TryReadSchemaVersion going internal behind CultNetDocumentRegistry.PayloadMatchesSchema) is covered by MESH-FOREIGN-Revert above.

Removes scripts/mutate-dotnet.ps1 and every scripts/*.entries.ps1 mutation-entry file for CultNet selection (networking, mesh, caching, fix-batch-2). Also drops the two live code comments in tests/GameCult.Mesh.Tests/CultMeshStreamingTests.cs that cited entry ids (MESH-KEY-Loosening, MESH-DEFAULT-Loosening), rewording them to describe the rule instead of the retired harness. Mutation testing now uses Stryker.NET on the cut's diff, run by Soul.

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 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.

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.

R-R says "recordKeys: [] answers empty" for v0 lowering. That holds for the raw v0 wire protocol server (CultNetDocumentRegistry.CreateRawSnapshotResponse, CultNetDatabase.CreateShardSnapshotResponse - fixed two commits back). It does not hold for CultMesh's typed convenience API: R-F, landed earlier in this cut, made CultMesh.EnsureV0Compatible run CultNetSelectionValidation. ValidateShape client-side before a request is ever sent, specifically so that "Keys=[]/[\"\"] is refused rather than silently lowered to 'every key'" (CultMeshSnapshots.cs:836-841). Once R-R made ResolveDefaultSelection's Clean(recordKeys) produce Keys=[] instead of Keys=null for an explicit empty list, every FetchDocumentsAsync(recordKeys: []) call now trips that existing R-F door and throws, instead of reaching the wire at all. Kept both rulings as each one's own owner decided them: the raw wire protocol answers empty (R-R); CultMesh's typed wrapper refuses before sending (R-F). Rewrote FetchDocumentsAsync_WithExplicitEmptyRecordKeys_AnswersEmpty, added two commits ago on the wrong assumption that CultMesh's typed API also answers empty, to FetchDocumentsAsync_WithExplicitEmptyRecordKeys_ IsRefusedClientSide, asserting the actual (and, on inspection, correct) R-F behaviour instead.

It already does (CultNetSelection.cs:389-394), landed by an earlier Hands pass on this branch (the "C# matrix Hands", after the parity table in the spec was captured) - so no production code changed here. What was still missing: SelectionParityVectorTests.RefusalCases() had a comment explaining why refuses_unmatched_cites_target_schema stayed "Rust-only", dated before that door check landed. The comment was stale and the vector was never added. Added it, plus refuses_cites_target_by_hash_shaped_alias (Self's ruling 2026-09-22: "the C# reference's alias rule is the rule" - C# only resolves a name-form alias, so a hash-shaped cites.target.schemaId is exactly the same unresolved-target case and must refuse at the same field). RefusalCases() now takes the fixture's schemas dictionary to reach schemas["leaf_a"].HashAlias. Verified on Yggdrasil: dotnet test tests/GameCult.Networking.Tests -c Release --filter FullyQualifiedName~SelectionParityVectorTests (the existing cross-runtime reader against the committed rs-written.json still passes, so this change does not depend on anything the Rust Hands owns).

SelectionRefusal now maps to a wire code (selection_invalid, cursor_stale, cursor_invalid, reference_outside_target) and a flat string-map details payload via to_wire_message(); the legacy array wire (gamecult.networking.v0) has no slot for either and never carries them, matching v0 peers ignoring them. - R-O: the snapshot cursor is keyed. CursorKey is a random 32-byte per-process key; Cursor::mint/compute_digest now take it and use HMAC-SHA256 instead of plain SHA-256, so a cursor forged without the key, or minted under a different process's key, is refused cursor_invalid. Cursor::parse stays public and decodes as_of without the key (Huginn's dependency); only verify_digest (called from select()) needs it. The cursor body itself is now length-prefixed fields, not a delimiter-joined string, so a record key carrying any character - including the pre-fix C# delimiter U+241F - round-trips. - R-T: matches_citation (the `cites` path) now checks every one of a citer's edges against its declared target before applying the citation's own role/key filters, closing F15: a corrupt edge used to hide behind an unrelated filter and never get validated. - The retired Rust mutation harness entries file (scripts/mutate-cultnet-selection-rust.entries.ps1) is deleted; tests pin the behaviour directly. Regenerated contracts/cultnet/interop/selection-vectors.rs-written.json from the shared fixture; it is byte-identical to what was committed, so R-T's fix does not change any existing fixture vector's outcome. The Rust reader still evaluates every vector in the committed cs-written.json (15/15) unchanged - that file predates the parallel C# Hands' R-N/R-S work and was not touched here.

The parallel C# pass landed the same correction on the reference server at 5e33d81/1afbaed/f8ba2d0 (pulled via rebase); this is the Rust side of it. lower_v0_list (packages/cultnet-rs/src/snapshot_query.rs) used to collapse a present-but-empty-after-trimming schemas/recordKeys list down to `None` ("no filter"), turning `recordKeys: []` into "every row" instead of the pre-cut server's actual answer of nothing. It now returns `Some(vec![])` for that case; the shared evaluator's matches_schema_keys_fields already treats a present-but-empty list as "match nothing" (R-E), so no further door/short-circuit logic was needed here - unlike the C# reference, serve_read_only_raw_snapshot never calls validate, so there is no v1 door for this shape to hit (the R-R fixup at 1afbaed doesn't apply to Rust). serve_read_only_raw_snapshot also now restores the caller's requested record-key order on the response (a stable sort by position in record_keys), matching the pre-cut server's HashSet insertion-order iteration instead of leaking plain snapshot-source order. Rewrote the stale test that pinned the old (wrong) "empty/blank list is no filter" behaviour into serve_read_only_raw_snapshot_omitted_v0_schema_list_is_no_filter_present_empty_or_blank_answers_empty, and added serve_read_only_raw_snapshot_keeps_the_requested_record_key_order. Hand-verified both by reverting each fix locally and confirming its own test fails.

From c606eb38f2e8e3893d1dd0fe768884112be98a30 Mon Sep 17 00:00:00 2001 From: Meta Vens Date: Tue, 22 Sep 2026 19:35:57 +0200 Subject: [PATCH 35/79] Back out the guessed R-N wire shape; R-N is pending on this branch Self's sequencing note (2026-09-22): the C# R-N pass (code/details on cultnet.error.v0) is running separately in C:\ws3 and will report the exact field names and code strings once it lands. Do not guess them. Reverts the earlier Error{code,details} fields on CultNetMessage, the SelectionRefusal::wire_code/wire_details/to_wire_message mapping, and their five tests. R-O, R-T, R-U's hand-probes and R-R are unaffected - none of them depend on the wire error shape. When the C# R-N commit lands, pull it, read its exact field names and codes, and implement the Rust mapping against those instead of a guess.

CultNetErrorMessage grows ForSelectionInvalid/ForCursor/ForReferenceOutsideTarget factories; both C# servers (CultNetDatabaseServer for snapshot+live, CultNetDatabaseSubscriptionServer) use them at every existing catch site, plus two sites that previously let the exception escape uncaught instead of reaching the peer (CultNetDatabaseServer's v1 subscribe snapshot branch, CultNetDatabaseSubscriptionServer's Subscribe around CreateProjectedSnapshot). CultNetSelectionCursorException now carries AsOf/Current for cursor_stale. R-P: CultNetDatabaseSubscriptionServer.CreateMatchedRecord (the live fast path) authorized against descriptor.SchemaId; the snapshot path (CreateProjectedSnapshot) already authorized against the wire id. Both now call the same CultNetDocumentRegistry.WireSchemaId (made internal, was private) so one id reaches the authorizer on the snapshot, live and reconcile paths alike. R-T(a): CultNetSelectionEvaluator.MatchesSchemaKeysFields no longer reads a Removed change's (always-null) document against Fields - it matches on keys/schemas alone and treats a field predicate as unknown instead of throwing TryGetIndexValue(null). R-T(b): EnsureWithinDeclaredTarget no longer skips the out-of-target check when TargetType is null; it checks against every registered leaf (unconstrained is a real, checked target set, not a bypass). CultCache's ResolveReferenceTarget also now infers the target from a many reference's CultRecordRef element when no explicit [CultReference(typeof(...))] is declared, which was the one remaining source of a null TargetType reaching that check on a real, testable path.

The message now encodes/decodes through the raw cultnet.schema.v0 path (encode_raw_cultnet_schema_message/parse_raw_cultnet_schema_message) instead of the generic serde_json::Value round trip every other CultNetMessage variant uses, because that path's BTreeMap-backed serde_json::Value would sort keys alphabetically and break the C# reference's fixed schemaVersion/error/routingHint/code/details map order - every optional key is written nil, never omitted, matching MessagePack C#'s always-five-key formatter. Adds the SelectionRefusal -> CultNetMessage mapping the fix-batch-3 comment in selection.rs called out as pending on the C# shape landing, covering all four codes (selection_invalid, cursor_stale, cursor_invalid, reference_outside_target). cultmesh-rs's one CultNetMessage::Error match gets an added `..` so it still compiles against the wider variant; it does not read code/details.

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 (:, 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.

An astral character (a surrogate pair: 2 UTF-16 units, 4 UTF-8 bytes) made the two counts disagree, so a cursor minted for a row keyed with one (Evaluator_CursorPositionUsesCodePointOrderMatchingTheRowTiebreak's astral key) failed to parse back - caught by that existing test on Yggdrasil, not a new one. The prefix is now Encoding.UTF8.GetByteCount(value); the digest's canonical string never round-trips through the byte-sliced reader (it is hashed whole), so this only had to be right for the cursor body, but one counting rule for both is what keeps AppendString actually unambiguous.

The response page's own schema now lists every property CultNetSnapshotResponseRawV1Message declares as `required` (present on the wire, nil included) rather than only the four that happened to be non-nullable - MessagePack-CSharp's map-mode formatter writes every declared key regardless of null, so `headers`/`documents` are always both present, one an array and the other an explicit null by projection. The old `oneOf: [{required:[headers]},{required:[documents]}]` matched both branches on every real page (both keys present) and so never validated anything; it is now `oneOf` over each key's type (array vs null), which is mutually exclusive. cultnet.raw-document-record.schema.json gained schemaName/schemaVersion/schemaContentHash (present on every real record, not previously in the schema at all - any real page would have failed additionalProperties:false on them). fieldPredicate's two oneOf branches each gained `not: {required: [the other]}`, so `values` and `number` cannot both be present (previously only `required` was checked, which does not exclude the sibling key). Added MiniJsonSchemaValidator, a deliberately small draft-2020-12 subset validator (type/required/additionalProperties/properties/items/const/enum/ pattern/minLength/minItems/oneOf/$ref, same-document and cross-document) - no schema-validation dependency existed in this repo, and this only needs to cover what contracts/cultnet/*.schema.json actually use. CultNetSchemaContractTests decodes real wire bytes from a live CultNetDatabaseServer (header projection, document projection, and a hop with edges) through MessagePackSerializer.ConvertToJson and checks them against the committed schema files, plus three fieldPredicate-shape tests pinning the values/number exclusivity.

Two schemas sharing one key collapsed into a single dictionary slot (last writer wins), so which row a reference/citation resolved to - and therefore whether a selection matched or refused reference_outside_target - depended on row insertion order. byKey is now a bare-key -> row-list index, and a shared TryResolveReferenceTarget searches each edge's declared leaf set to resolve the one row that actually belongs to it, deterministically regardless of order (Soul's P2, tested both ways). EdgesFor's page-row anchor index is keyed the same way for the same reason. R-W (S-2): EnsureWithinDeclaredTarget's equivalent check (now folded into TryResolveReferenceTarget) now runs for every edge a reference carries, before a citation's own key/schema filters that edge out - not only for the edge the citation happens to ask about. A many-reference edge into a schema outside its declared target refuses the selection even when the caller's key filter would otherwise skip past it without ever inspecting it (Soul's P3). S-8: the dead `targetType ?? typeof(object)` fallback is deleted. D11 already refuses every reference shape whose target the cache cannot infer before it can reach the evaluator, so the branch had no reachable fixture. R-Y: the cursor's HMAC now covers its own body (asOf, ordinal, schemaId, recordKey) as well as the selection. Before this, a forged cursor could reuse a legitimately minted digest while rewriting the ordinal or record key underneath it, since nothing about the body was ever authenticated (Soul's P4).

A new test decodes real bytes for all four refusal codes (selection_invalid, cursor_stale, cursor_invalid, reference_outside_target) against the schema. MiniJsonSchemaValidator: - implements minimum, maximum, maxLength and maxItems, which were declared in committed schemas (fieldPredicate's number pattern, selection.limit, ...) but silently never checked; - anchors `pattern` to a full match (Index==0 && Length==value.Length) instead of Regex.IsMatch's "search anywhere", so .NET's `$` (which, unlike ECMA-262's, matches immediately before one trailing newline even without RegexOptions.Multiline) can no longer let e.g. "5\n" pass a schema author wrote as "exactly one digit"; - refuses a schema node that uses a keyword this validator gives no constraint semantics to, instead of silently ignoring it. Running every committed contracts/cultnet/*.schema.json schema through this found 12 such uses, none reached by any existing test: `allOf`/`if`/`then`/`else` in cultnet.database-change-raw.schema.json, and `uniqueItems` (six places) plus one `anyOf` in the cultmesh.verse-catalog-*.schema.json pair. contentEncoding, $schema/$id/$defs/title/description/default and the x-cult-runtime-type vendor extension are treated as metadata with no constraint semantics to implement, not refused.

Each new test drives the public selection/evaluator surface with a fixture built to make the rule's failure observable in the answer, not in the code's spelling - several needed new fixtures (a mixed numeric/string alias, an index alias differing from its member name, two reference members resolving to one target) because their absence is why the mutant survived in the first place. Two of the five EdgesFor order-flip mutants (To.SchemaId/To.Key) are not addressed: within one hop direction an edge's (From, Role) already determines its To deterministically, so no legal selection can tie anchor+From+Role while To differs. Recorded as a likely equivalence, left for Stryker's own verdict rather than forcing a contrived test.

Both indexes are now keyed by (schemaId, recordKey), matching CultCache's per-schema key uniqueness. R-W (S-3), Rust half: a selection carrying both `cites` and `cited` computed one `cited_direction` flag and applied it to every edge in the batch, so the `cites` edges vanished whenever `cited` was also present. Each `EdgeMatch` now carries its own `EdgeAnchor` (Citer/Citee) set at the point it is produced, and the page filter/sort anchor each edge by its own hop instead of one shared direction. Tests: two schemas at one record key, in both row orders, agree on which row a citation resolves to and which row counts as cited; a selection with both hops returns edges from both directions.

Tests: an in-module unit test (cursor_tests, next to Cursor, where the private digest field and the length-prefix helpers are reachable) splices a genuine digest onto a rewritten ordinal and a rewritten record key and confirms verification fails on both; an integration test confirms two cursors minted for different positions under the same selection and key never share a digest.

There is no workspace Cargo.toml tying this crate to its siblings, so cargo-mutants treats this package's own directory as the whole tree it copies - every one of those paths escaped it, and the unmutated baseline build failed on all 22 with "No such file or directory". There was no mutation evidence for the Rust half of this cut at all. Fix: vendor byte-identical copies of the 22 schemas under packages/cultnet-rs/contracts/cultnet/, git-tracked so they travel with the package, and repoint every include_str! at the vendored copy. A build script staging files into OUT_DIR was the other option named for this rule, but it does not actually solve the problem: the script would still have to read from outside the package to find its source, and would fail the same way inside cargo-mutants' copy. Vendoring is "another route that keeps every source path inside the package." Vendoring duplicates files this repo treats as canonical (contracts/cultnet/*.schema.json, shared across every runtime per docs/cultnet-selection-cut.md section 1), so a new test, schema_discovery_contracts.rs, compares every vendored file against its repo-root original byte for byte and fails loudly on drift. It skips (not fails) when the canonical contracts/ tree is not present beside the package - the isolated-copy case R-AB exists to survive - so the check cannot reintroduce the same escape it guards against. cargo-mutants run on the crate, at least covering this cut's diff: report to follow with every survivor triaged.

That was true before the Rust alias port; it is not true now. Both runtimes resolve a schema alias the same one way (strip a trailing .vN, compare the remainder against the descriptor's declared SchemaName): nameAlias resolves through both, and hashAlias - kept in the fixture on purpose - is refused as unmatched by both, since neither runtime's production call sites produce or accept it. Prose-only change to this shared fixture file, as ruled: no vector values, schema ids, or row data touched. Also recorded for Self's map: cultnet-rs's alias port (R-E) does not carry SchemaVersion or CompatibleSchemaIds - no Rust call site needs either, so schema_alias::matches folds them away and agrees with the C# rule only on the subset it actually uses (candidate/id/name comparison, not version or compatibility-list matching).

There is nothing to vendor - an isolated Rust-only copy can never satisfy that test's premise regardless of what this crate does with its own files. That one test now skips (with an explanation) when the canonical contracts/ tree is entirely absent, rather than panicking and failing the whole suite over a cross-runtime artifact the isolated copy cannot produce by construction. Verified locally by hiding contracts/ entirely and rerunning the full suite (217 tests across every binary): unchanged pass count, same as with it present.

Probed the real wire bytes a stored CultRecordRef produces (GameCult.Caching.MessagePack.CultRecordRefFormatter.Serialize writes only value.Key.Value - a probe against a real document confirmed the serialized "Design" field is the bare msgpack string "a-eq", nothing else). The wire carries no schema for a reference; C#'s rule was right and Rust's exact-(schema,key) lookup assumed a schema id the edge never actually carries. Row::references() now returns (role, target_record_key, payload) - a bare key, matching C#'s ReferencesOf. matches_citation/build_incoming_index resolve through the new resolve_reference_target, which mirrors C#'s TryResolveReferenceTarget: search every row sharing the key (by_key is now keyed by record_key alone, grouping rows across schemas) for the one whose schema falls inside the declared leaf set, refusing deterministically (by schema id, code-point order) when none do. Folds D9's leaf-set check into resolution itself rather than a second ensure_within_declared_target pass - deleted, since it also dropped the old bypass-on-empty-leaves behaviour C# never had (empty leaves always refuses when a candidate exists). Also moved the citation's own role filter before resolution in matches_citation (mirroring C#'s ReferenceMembers(descriptor, citation.Role), which narrows to that role's members before R-W's per-edge check ever runs) - found while landing R-AF's vectors: Rust was checking every declared reference a row carries regardless of the requested role, a stronger and different guarantee than the C# reference actually gives. R-AG. read_length_prefixed_fields used unchecked usize addition (pos + len) to bound a length prefix parsed from the wire; a hostile prefix near usize::MAX overflowed and panicked. Uses checked_add now, returning None (which Cursor::parse already turns into a typed CursorInvalid) the same way every other malformed shape here already does.

R-AF adds a "citer_narrow" schema (real SHA-256 id, computed the same way CultDocumentRegistry does - a probe run against a type matching the eventual C# type's exact namespace/nesting confirmed it) whose one reference targets leaf_a only, plus rows for both shapes from Soul's table: a lone out-of-target row at a key (refuses), and two rows sharing a key where only one is in-target (accepts, resolving the in-target one regardless of row order). Also drops "targetSchema" from every reference entry: it was never anything but documentation (SelectionParityVectorTests.BuildDocument and cultnet-rs's build_row both already read only targetKey) and keeping a field the wire does not actually have would contradict the rule R-AF just established. R-AJ adds a tied-ordinal pair across leaf_a and leaf_b, with keys chosen opposite to the real schema ids (probed) on purpose, so a schemaId-first order and a recordKey-first order are forced to disagree regardless of which real id happens to sort first - see the row-tiebreak test this enables. selection-vectors.cs-written.json and selection-vectors.rs-written.json are regenerated from the new fixture (CULTNET_WRITE_VECTORS=1 on both sides) and cross-checked in both directions locally.

Landing these exposed a real, pre-existing cross-runtime scope difference in R-W unrelated to R-AF: Rust checked every declared reference on a row regardless of the citation's requested role; C#'s ReferenceMembers(descriptor, citation.Role) narrows by role first. Fixed on the Rust side (previous commit); hop_by_role_cites_exact_id and cites_target_by_name_alias keep an explicit Keys scope here anyway as belt-and-suspenders. Also corrects S-12's last stale comment: cites_target_by_name_alias's "Confirmed cross-runtime defect" note was already false - the alias port fixed it - and still called it confirmed. R-AJ: CultNetSelectionSurvivorTests.cs's row-tiebreak fixture (Evaluator_BreaksAnOrdinalTieBySchemaIdThenRecordKeyInBothDirections) was degenerate - probed by hand-reverting the source and swapping the tiebreak's two ThenBy calls, it still passed, because whether the old 3-row fixture discriminated the swap depended on which of SelLeafA's/ SelLeafB's real schema ids happened to sort first, and on this repo's ids it didn't. Rewritten to assign row keys relative to the schema ids discovered at runtime (low-sorting schema gets the high-sorting key and vice versa) so the two candidate orderings are always the exact reverse of each other; reprobed the same mutant afterward and it now fails. Adds a direct EdgesFor test (constructing FullEvaluation/EdgeMatch by hand) pinning "From.Key before Role" in the five-key edge tiebreak - the two existing EdgesFor tests each tie one of those two components, so neither could tell a Role-first mutant from the rule.

Adds citer_narrow() (the shared fixture's real schema id, distinct from this file's own local NARROW_CITER) to the fixture machinery, and two direct behavioural tests (shared_key_resolves_to_the_row_inside_the_declared_target_in_either_row_order, shared_key_refuses_when_the_only_candidate_is_outside_the_declared_target) pinning both shapes from Soul's table at the select() level, plus a shared-fixture vector case for the accept shape and an evaluation_refusal_cases entry (expected_evaluation_refusal, read by the matching C# addition) for the refuse shape. Rewrites cites_refuses_a_row_carrying_an_unrelated_edge_outside_its_declared_target (renamed cites_refuses_an_out_of_target_edge_under_the_same_queried_role): its original shape queried one role while expecting refusal from an edge under an unrelated role, a stronger guarantee than C#'s own R-T(F15) test gives (same role, two elements) - found because it broke once matches_citation's role-filter order was fixed to match C#. The new version mirrors C#'s actual test shape. R-AG: hostile cursor tests feeding Cursor::parse a length prefix near usize::MAX (Rust's own proven overflow), near i32::MAX (C#'s proven overflow, fed here too per the ruling - neither side's tests are evidence about the other), a prefix wider than any integer type, and a negative-looking prefix - all under std::panic::catch_unwind, asserting a typed CursorInvalid and never a panic. R-AJ: edge_order_is_from_key_before_role_when_both_vary_at_the_same_anchor (a both-hops selection with a hub/other citer pair whose keys and roles are deliberately anti-correlated, so a Role-first mutant and the real rule disagree) and row_tiebreak_orders_by_schema_id_before_record_key_when_both_vary_at_a_tied_ordinal (the same anti-correlation trick applied to order_rows, computed against the real leaf_a/leaf_b ids at runtime). FixtureRow gains #[derive(Debug)] - needed for an assert message on the new evaluation-refusal-case writer, harmless elsewhere.

ReadLengthPrefixedFields tested pos + length > bytes.Length in int math; a length prefix near int.MaxValue overflowed the unchecked add, slipped past the guard, and Encoding.UTF8.GetString threw ArgumentOutOfRangeException instead of this method returning null the way every other malformed shape already does. Promotes to long before the add, which cannot itself overflow (both operands stay far under long's range), so the guard sees the true sum. CultNetRudpSchemaServer.DispatchAsync gains a catch around the handler invocation: HandleSnapshotRequestV1Async already answers cursor_invalid/selection_invalid/reference_outside_target for its three typed exceptions, but nothing stopped an untyped one from an unanticipated bug reaching DynamicInvoke's caller and stalling the poll loop for every other peer. Answers nothing on the wire (an exception this generic carries no typed refusal to report) and drops the one malformed dispatch, the same as an unregistered handler already does. Hostile-cursor tests (CultNetSelectionFixBatchTests.cs) feed CultNetSelectionCursor.Parse a length prefix near int.MaxValue (C#'s own proven overflow), near usize::MAX (Rust's proven overflow, fed here too per the ruling), wider than any integer type, and negative-looking - each asserted to throw the typed CultNetSelectionCursorException. R-AK. Deletes ReferenceMembers's `!member.IsReference` guard. CultCache.ReferencesOf (CultCache.cs:262-278) already searches only its own reference members for a role match and returns empty for anything else; index aliases are unique per descriptor, so a data member's own role string can never coincide with a reference member's. Verified before deleting: traced ReferencesOf's role lookup directly rather than trusting the ruling's premise. A second copy of the same exclusion here was duplicate authority, not a second decision.

The existing round-trip tests parse the rendered string back through f32::parse and compare bits, which can still agree with a wrong bit-extraction when the wrong value happens to parse back to the bits it was carelessly derived from; none of them assert on the rendered string's shape or magnitude directly. Add a subnormal-shape test (2^-149 is "0." plus 149 fraction digits, not an astronomical integer and not one exponent off) and a normal-path test where the fraction bits are identical to zero's (1.0 and 2.0) so only the implicit leading bit the | folds in carries the value.

Two new tests isolate the other two components of EdgesFor's comparator: role (same citer, same target, two roles - Citation.role: None matches any reference) and from.schema_id (two different-schema citers sharing one record key and role). Both confirmed to kill their own dropped-clause mutation by hand (reverted after).

Confirmed to kill a last-wins mutation by hand (reverted after). Also extends the shared vector case list with shared_key_design_resolves_the_first_in_target_candidate_- in_row_order (paired with the fixture/vector commit). To.SchemaId/To.Key were re-checked per Self's ruling: within any one page_position bucket, `cites` always ties every edge's To to the query's own single target, and `cited` always ties it to the anchor row's own identity - the only way for To to vary at a tied page_position is a mixed cites+cited hop on one row, which always ties or untangles via From first. No construction was found where To is the sole discriminator; the earlier "equivalent within one hop direction" claim holds. No code change, no artificial test.

C#'s [MessagePackObject]/[Key("name")] map formatter already does this by default (confirmed byte-for-byte below); Rust's `to_vec_named` encoding for these four types used `skip_serializing_if = "Option::is_none"`, which omits the key instead - the gap the map cited ("C# writes nine fields with nils, Rust omits absent ones"). Removes skip_serializing_if from Edge, RawDocumentHeader, SelectionDocumentRecord and SelectionPage, keeping #[serde(default)] for decode-side robustness. Selection (the request type) is untouched - out of this ruling's scope, and the map already confirmed the request side agrees between runtimes. Adds tests/selection_wire_parity.rs: RawDocumentHeader and Edge, each carrying several absent optionals, encoded via to_vec_named and compared byte-for-byte against hex captured from a real MessagePack C# 3.1.7 run (same pattern as error_message.rs's csharp_hex vectors) - both now agree exactly. What is NOT done, and why: R-AP also called for "Select gains projection, so the thing the vectors test is the thing that decides." In C#, projection (header vs document, ToRawRecord/ToEdge/FromRecord) is owned entirely by CultNetDocumentRegistry.SelectPage/SelectAll (GameCult.Networking), not by CultNetSelectionEvaluator.Select/Page - the evaluator returns raw Rows/ EdgeMatches and knows nothing about a document's payload serializer, which only the registry's bindings own. Moving page assembly into the evaluator without threading a caller-supplied serializer (the same pattern ordinalOf/ shardIdOf already use) would give a schema-generic evaluator per-binding wire knowledge it should not own; threading a serializer callback in is buildable but changes SelectPage/SelectAll's own signature and every caller, plus the parity-vector harness's construction - a materially larger change than this pass's remaining scope. No vector yet exercises the real CultNetSnapshotResponseRawV1Message/select_page output byte-for-byte; only the two nested wire types in isolation. Flagged for the operator per the brief's own stop condition. R-AQ, updated: type-level byte parity for the nested wire shapes (Edge, RawDocumentHeader) is now real and vector-tested. Whole-message byte parity for cultnet.snapshot_response_raw.v1 is still not - the smaller claim (this cut's page bytes agree only where R-AH's fixed-shape rule reaches, and projection ownership is still split between the evaluator and the registry) is the true one until "Select gains projection" actually lands.

The all-absent header gets incidental cover because it is nested inside the 376-byte envelope test; the edge has no such cover, so a C# edge encoder that resumed omitting a null payload/payloadEncoding would still pass every other test here - exactly the asymmetry R-AP existed to kill. Adds EdgeAllAbsentMatchesTheConstantCommittedIntoTheRustTest, asserting the same constant against MessagePackSerializer.Serialize. Flipping one hex digit of RustEdgeAllAbsentHex fails the new test only, confirming it is not vacuous.

Traced instead of asserted: TryResolveReferenceTarget (C#) and resolve_reference_target (Rust) resolve a reference purely from the citer's schema, the role, and the record key, against the evaluation's own fixed candidate index (byKey/by_key) - no edge- or caller-specific input steers which candidate wins. Once From and Role tie (pinning the citer's schema and the declared target type/leaves) and To.RecordKey also ties, the resolved row - schema included - is forced identical by construction, in both runtimes, every time. No mutation can distinguish it because no input can, so it was deleted rather than recorded as "equivalent": a component nothing can distinguish is a line every future reader must reason about for no behavioural gain. Deletes the To.Descriptor.SchemaId/to.schema_id() ThenBy/then_with from CultNetSelectionEvaluator.EdgesFor and selection.rs's page_edges sort, and updates the comments (in-code and the Survivor 5 test block) that described the old five-key chain.
