The cultnet.error.v0 contract is not decodable across runtimes, and the
interop CI lane has been red for 40 main runs. Cut 0 unblocks the lane;
Q1, Q2, Q3 and Q8 must be ruled before Cut 1.

Maps the four 2026-09-30 rulings. Cut 2 merges only with Cut F (Soul:
expiring reliable sets pin the bound). Adds Cut D (a failed send to one
peer no longer aborts a document server poll) and C# Cut 2c. Opens
Q-A7, Q-A8, Q-A9; Q-A7 and Q-A9 block Cut F.

Applies the Q-A1/Q-A2 rulings (one public meaning: Acknowledged means
delivered). Adds Cut 1b (every session ending drops what it owed; flush is
bound to its session) and Cut 1c (how a new generation is recognised,
blocked on new Q-A6). Probes at 3bf1c0c reproduce G1, G1b, G2 and G3 in
all four runtimes. Kotlin trails as Cut K pending Q-A5.

Adds the pass 4 probes, the journal-floor rule, and the re-taken Cuts 4-6, salvage and ledger.
Records Q-P5 A: a primary that cannot log a committed change throws CultNetShardLogException.

Imagination pass 1. Probes found acknowledged ordered frames lost in live
sessions in every runtime; the map derives Delivered at the sender from a
correct receiver watermark. Operator questions Q-A1..Q-A5 open.

Imagination rebuilt the writer-thread scheduler Soul pass 3 proposed: it
deadlocks exactly as bcae483 did (deleted in 4562340). The map keeps per-writer
delivery, validates getters before minting, isolates observers, and moves the
shard log onto a gate-held journal. Q-P1..Q-P4 open.

Re-anchored to current main and Aetheria fire-control-12. Grouping gets its own
[CultInspectorGroupBy] attribute; CultIndex stays unique. Sequenced with variants
C2a/C2b/C3 into one joint release (cultlib 1.0.61, Studio 1.5.0); Aetheria
annotations fold into variants C4. Q6 and Q7 open.

The map carried only on codex/studio-grouping moves to main. The operator
ruled Q2 A, Q3 A, Q4 A on 2026-09-30. Q5 is overtaken: one Studio release
with variants C3. A refresh pass is due before Hands.

A variant record (v2 store, slot 4 [baseKey, overrides], empty payload)
holds top-level Set overrides and is resolved in the admitting hold.
Readers see complete documents. A base edit re-resolves dependents in the
same commit. Rulings honoured: Q1 a plain Upsert at a variant key is
refused; Q4 an override follows the plain-record outcome (a dropped slot
soft-drifts and is shed, an undecodable value refuses); Q5 the v2 header
only with variants; Q6 the directory store and CultNet refuse variants
(after selection, typed, subscriptions withdrawn). Self's defaults:
invalid overrides are refused at write; R6 is extended to indexes (no
variant shares an indexed value with another record). The held index is
truthful (value to holders, smallest key wins among plain duplicates).
A conditional merge onto disk is judged on the merged set.
Soul made five passes. The held index keeping one key per value caused
three rounds of store-bricking findings until the owner was fixed.
Caching 249, Networking 293, Mesh 262, cross-runtime interop 36/36.
Follow-ups: TS/Python plain-duplicate parity, a subscription id on
per-change refusals, a removal-order test.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
C#, TypeScript, Python, Rust and CultMesh refuse an unknown
cultcache.store.* header and a fifth record slot, naming the version or the
key and schemaId. The silent slot-skipping and C#'s ignored header are
deleted, and CultMesh's second record decoder is gone. Shared vectors are in
tests/vectors/document-variants-c0/. v1 stores stay byte-identical. At base,
the single-file commit's read-modify-write rewrote a v2 store as v1, which
lost data; it now refuses.
Soul passed it. Cross-runtime interop was run and passes. Three C#
Caching tests fail on Linux at both base and tip: they are Windows
share-mode tests (a FileShare.Read handle blocking delete/replace), which
cannot pass on Linux.

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

The Rust runtime gains the reference's content chunk messages on the raw
path, CultMeshCdnArtifactManifest with wire-ordered metadata,
normalize_hash, pack_content, validate_manifest,
answer_content_chunk_request (every bad request is answered, byte
identical to the reference server) and fetch_content (one owner of
receiving-side verification; refuses zero-size floods and unnormalised
hashes before any request). Vectors run both ways between C# and Rust.
The operator ruled Q-BP1 A: chunks travel on the session already held.
This is the explicit Rust content path until an authenticated connector
exists.
Soul passed it after two fix batches. cultnet-rs: content 24, cultnet 53,
rudp 7, lib 110. cargo-mutants on content.rs misses 0.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A C# caller that leaves ChunkHash, MessageId or RecordKey null writes msgpack nil; the
reference reads it back as null, treats it as blank and answers found:false. Rust now
decodes nil as blank in content chunk requests, so those requests are answered with the
reference bytes instead of dropped. Three nil vectors from the reference server are
judged by decoding them in Rust. Record two content-plane limits in the parity scope.

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

Q3 is ids everywhere, minted on load (not opt-in). Q4 is soft drift for
dangling overrides, which supersedes one of the target's refusals. The
others were ruled as recommended.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The target (2026-09-17, with the operator's rulings) lived only on
codex/document-variants. The cut map is Imagination's pass of 2026-09-29.
Its operator questions Q1-Q7 are open.

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

The `==`->`!=` and `< 0`->`> 0` mutants on Extract's orientation check are
both Killed. The one survivor, `OrientationSign[axis] <= 0`, is an
equivalent mutant, not a coverage gap: OrientationSign only ever holds ±1,
so `< 0` and `<= 0` agree on every value it can produce. No vstest
coverage-based false survivor has actually been confirmed for
GameCult.Geometry; remove the withdrawn claim and keep the correct notes
about full-SHA --since, safe.directory, and config-change scope fan-out.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Stryker's diff-scoped run against this cut reported CultGeometrySurfaceNets
.Extract's `if (inside == (OrientationSign[axis] < 0))` - the sole authority
for quad winding after F4's fix deleted the geometric cross-product fallback
- as a Survived Equality mutation (== -> !=). Hand-mutating it and running
dotnet test directly failed 4 of 38 SurfaceNetsTests (the three per-axis
corner-order tests and the outward-winding test), confirming it is a real
vstest coverage-based test-selection miss, not a genuine gap. Recorded this
as a second confirmed case alongside the mtp/static-readonly-initializer
caveat, per this cut's verification requirement to hand-confirm any survivor
that looks like it must be covered.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The three TryGetOtherEndpoint survivors were triaged as a vstest coverage
false-survivor, mirroring the confirmed mtp/static-readonly caveat above.
That triage was wrong: the actual mutant is `return false` -> `return true`
inside each per-axis guard, which is equivalent (it makes the method report
an edge going nowhere, so the caller compares a sample against itself and
skips it exactly as it would with a correct `false`). Rewrote the paragraph
to say so, and removed the unsupported claim that this project has a
confirmed vstest false-survivor case. Also recorded, per this cut's
verification requirements, that `--since` needs a full commit SHA and that
`safe.directory` must be set in a container.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Three TryGetOtherEndpoint boundary-guard mutants (per-axis "if (x + 1 >=
sizeX) return false;" forced to "if (true) return false;") were reported
Survived despite being exercised by the X/Y/Z open-boundary tests. Hand-
mutating all three and running dotnet test directly failed 11 of 24
SurfaceNetsTests, confirming a vstest-runner coverage-attribution false
survivor (same class of caveat already recorded for CultMath's mtp runner,
here under the default runner). Recorded under Known tool caveat.
Separately, adding stryker-config.json in the same cut that first uses it
defeats --since line scoping: Stryker fell back to mutating the whole
GameCult.Geometry.csproj glob ("Non-CSharp files in test project were
changed"), not just the new files, which is why the run's survivor list
includes CultGeometryIsoSurface.cs, CultGeometryDocuments.cs, and
CultGeometryPrimitives.cs. Recorded under Follow-ups so a later diff-only
cut isn't surprised by the difference.

Adds SurfaceNetsTests.cs and QuadNormalsTests.cs covering the sign
convention, edge naming, outward winding, vertex placement (midpoint and
unequal-crossing means, origin/cellSize), closed-sphere welding and
Euler characteristic, an ambiguous checkerboard cell's even-but-not-2 edge
usage, open-boundary quad suppression, determinism/ordering, and
face-weighted normals (sliver-vs-large-quad area weighting, unit cube
normals, zero-area/untouched-vertex degenerate case). Adds
stryker-config.json (vstest runner; this project is NUnit 4, not xunit.v3)
and records GameCult.Geometry as scoped, diff-only, in
docs/mutation-testing.md's follow-ups.
