-
-- C# reference runtime: `src/` (`GameCult.Caching`, `GameCult.Networking`,
-  `GameCult.Mesh`, `GameCult.Geometry`, `GameCult.Unity`). Build and test with
-  `dotnet build CultLib.sln` and `dotnet test CultLib.sln`.

-  Application path: `src/GameCult.Mesh/docs/getting-started/README.md` and

-## Live And Planned
-
-Live: typed CultCache persistence, CultNet schema-v0 transports and native RUDP,
-CultMesh nodes with Verse discovery, shard replication and authority leases,
-the geometry documents, and CultUI for Unity. The browser client boundary
-(`packages/cultmesh-browser`, `GameCult.Networking.WebSockets`) is proven on
-loopback under an explicit `local-development` trust policy by

-# C2a land map
-
-What C2a (`hands/variants-c2a`, a5c7954e) must still prove to merge to main, measured
-on 2026-10-22 against main 7a8933b0 and the 2.0.0 release candidate
-`hands/cultlib-unity-release-2.0.0` (5b5d8573, which carries f91e30ed). The land cut
-is the merge plus the gate. Everything else is classified below. Governing ruling:
-`cultlib-gaps:ruling:release-now-c2a-bumps-format`.
-
-## Cut sequence to main (2026-10-27, branch head 7c7cc799)
-
-Landed since the facts below: `land-c2a` (h1), `land-c2a-merge-api-docs` (h1-h6), the 2.0.1 and
-cultcache-rs 0.3.1 merges (5baa02fa, f54472e5), `land-c2a-gate` r4 (h1), `store-gate-one-owner`
-(h1-h7, Soul s6) and `restamp-on-write` (h1-h2, 8ee66714..7c7cc799, Soul s2 holds). One static `Owns`
-decides ownership for cache and cacheless writers, and the High finding
-`cut-land-c2a-gate.s1.reflist-record-read-only-at-head` is Fixed by 7c7cc799. origin/main is 73e684b1:
-21 commits past the merge base 02cf04b5, all docs and research (15 files, +1879, none under src/,
-tests/ or packages/, none on a path the branch changed). What stands between the branch and main, in
-order:
-
-1. **claimant-one-owner** (spec r1 at 7c7cc799, Hands then Soul). Restamp's Soul s2 left four Lows
-   on the landing path. Which entry reads a persisted entry is chosen twice (`Claimant` at
-   CultCache.cs:703-750, `ClaimantEntry` at :797-799), and so a cacheless writer handed registry {A,B}
-   overwrites a record that a cache with {A,B} holds read-only (probe X4). The cut keeps one `Claimant`
-   precedence over a by-id/by-name lookup that the registry or a single entry supplies. A cacheless
-   writer with a registry then takes its claimant from that registry. The cut also pins the
-   unpublished-id case and fixes the stale test comment. It closes `claimant-selection-duplicated`,
-   `cacheless-inverts-registry-claimant`, `unpublished-id-guard-unpinned` and `stale-flag-copy-comment`.
-   It is kept apart from the gate so that Soul can falsify it alone. Its files (CultCache.cs, the
-   persistence contract, RestampOnWriteTests.cs) are disjoint from the gate's, so it can run before or
-   beside step 2. The second cut to land rebases.
-2. **land-c2a-gate** (spec r7 at 7c7cc799, Hands h2 then Soul). The ref-list gate does the same write
-   at 2.0.1 and at head and compares schema ids. The committed vectors are pinned byte for byte under a
-   fixed clock, and every stage counts its cases. r7 drops r6's head-only restamp assertions, which
-   `RestampOnWriteTests.TheCommitted1060VectorsListRecordIsWrittenUnderTheHoldersOwnId` already pins.
-   It also drops the red-at-193cf1c3 run, because restamp is measured. The cut closes
-   `single-vector-hand-edit-passes`, `gate-green-with-no-refusal-probes` and follow-up
-   `gate-reads-1x-written-store`.
-3. **Ledger** (Self, no Hands; can run now, beside steps 1 and 2). Each of these is in force though
-   its fix has landed:
-   - The seven `cut-land-c2a.s1.*` findings. `land-c2a-merge-api-docs` carried their pins (source reads
-     2026-10-27: GameCult.Caching grants InternalsVisibleTo only to `.Tests` and `.MessagePack`, the
-     residual being follow-up `caching-messagepack-ivt`; PreCut2StoreFormatTests pins "with a suffix
-     of"). Close each one against its commit, or defer it. `stale-unity-plugin-dlls` defers to the
-     Unity 3.0.0 release cut (the plugins are 2.0.1 builds, 1eeb1a01).
-   - `cut-c2a-write-set.s1.untouched-dropped-slot-resurrects` and follow-up `slot-reuse-contract-doc`.
-     Ruling `slot-reuse-documented` decided the behaviour, and the paragraph is in
-     cultcache-schema-compatibility.md:64-66.
-   - `cut-restamp-on-write.s1.websockets-tests-unreported`, Fixed by h2 (s2 promise
-     `websockets-tests-reported` holds).
-   - Follow-up `gate-bound-test-tighten`, carried by restamp r2 (50362447, a768b821). Close it if
-     restamp's Soul passes measured it; otherwise route it.
-   - After steps 1 and 2 hold: the four s2 Lows, the two remaining `cut-land-c2a-gate.s1` Lows and
-     `gate-reads-1x-written-store`.
-4. **Consumer pins** (ruling `unpinned-consumers-at-land-3`, follow-up `consumer-pins-before-land`).
-   Brokkr, Aquarium, Ymir, AquaSynth and Mimir have no `CultLibRevision`/`VerifyCultLibRevision` guard,
-   and each builds against the sibling `..\CultLib` checkout. In its own repo, each adopts Aetheria's
-   guard at the 2.0.0 tag, with one Hands per repo, before the merge reaches main. The pins touch no
-   CultLib file, so they can start now and run in parallel with steps 1-3. Eve and Gjallar get no pin
-   (ruled). The step is done when each repo's guard fails a build against a CultLib checkout at
-   another revision and passes at the tag, and the follow-up is resolved.
-5. **Main into the branch, then full verification.** After steps 1, 2 and 4, `git merge origin/main`
-   into `hands/variants-c2a`. It should be clean, because main's commits since 02cf04b5 are docs and
-   research only. Re-check that before merging (`git diff --stat 02cf04b5 origin/main -- src tests
-   packages unity`). Then run every suite at the merged head on Yggdrasil: Caching, Mesh, Networking,
-   Geometry, WebSockets, ConsumerBuild, InteropPeer, cultcache-ts/-rs/-py, cultnet-ts and cultmesh-ts.
-   Run `old-reader-refusal.sh gate` for csharp, typescript, python and rust. If main gained code by then,
-   a Soul pass covers the merge.
-6. **Land.** The land is `git merge --no-ff`, never a squash, so the SHAs that every report and verdict cites stay reachable from main (skip the branch's non-building commits with `git bisect --first-parent`). Steps 1 and 2 closed at 723b7996 (claimant-one-owner, land-c2a-gate); step 5 closed at the merge commit 3157d4b3 (Soul `cut-land-c2a-main.s1` holds). Step 3 closed except `cut-land-c2a.s1.stale-unity-plugin-dlls` and `cut-land-c2a-gate.s2.mutation-table-reads-gate-as-zero`, which wait on the 3.0.0 release cut and the Eureka tools respectively; step 4 closed with `consumer-pins-before-land` (pins since 2026-10-22). Run `git merge --no-ff hands/variants-c2a` onto main, with an empty diff against the
-   verified head. There is no tag: tags, the Unity plugin rebuild and `declared-range-gate-own-version`
-   belong to the 3.0.0 release cut. Open follow-ups `c2a-load-slower` (load 2 to 2.3 times slower than
-   main on a synthetic Aetheria catalog) and `drift-write-ownership-leaves` do not say "before land".
-   `c2a-load-slower` still needs a reason or a fix before the 3.0.0 release, under
-   `cultlib-gaps:ruling:database-shaped-built-for-load`.
-
-## Facts
-
-**1. The merge.** A trial `git merge origin/main` on a5c7954e gives 12 conflicted files and
-33 hunks of about 950 marker lines (CultCache.cs 17 hunks/196; cult-cache.test.ts 337;
-single-file-messagepack-backing-store.ts 4/106; rs lib.rs 2/51; VariantTests 51; three
-CHANGELOG add/adds; store-composition contract 32; Directory store 14; InteropPeer 21).
-Main moved 4.8k lines in the cache runtimes since base 1a12bc2d. Three semantic collisions
-are not textual:
-
-- *Durable record identity has two owners.* Main added `CultStoredDocument.PersistedSchemaId`
-  and `CacheBackingStore.MarkWritten` (73d438db, afd799ba, 3f6dda8b). Conditional commit
-  compares the persisted schema id plus storedAt. C2a already owns this as
-  `StoredSchemaId` + `StoredVersion` (SHA-256 of the stored bytes, which names the schema
-  id and storedAt) set by `CultCache.Wrote`. After the merge, 9 references in
-  ConditionalCommitTests and the contract name main's owner. The version is the owner.
-  PersistedSchemaId and MarkWritten are deleted, and main's +309 test lines are ported as
-  pins against StoredVersion. 2.0.0 ships MarkWritten as protected API, and C2a also
-  removes `SerializeSnapshot`/`DeserializeSnapshot` overrides and changes `ConditionsHold`.
-  C2a is therefore a major release (3.0.0), which semver forces.
-- *TS store commit moved.* Main's `store-file.ts` (0e6452c9, 0010ee92; 391 lines) now owns
-  commit, replace and the `<path>.lock`. C2a's v3 read and keep-v3-on-rewrite
-  (`STORE_FORMAT_ELEMENT_IDS`) lives in the old store file and must move into store-file.ts.
-- *Rust decode door.* Main's cultcache-rs 0.3.0 grown decoder (`decode_stack`, fc630d3b)
-  must sit under C2a's `readable_store_format` and v3 `decode_store_file`.
-
-**2. The gate already holds; it needs a test, not a format change.** C2a stamps
-`cultcache.store.v3` (single file) or `...v5.directory-content-addressed-pages` exactly when
-a record holds an id (`HeaderFor`, CultCache.cs:3543). It also marks when a copied record
-decodes holding one (`CopiedHoldIds`, :4285). The 2.0 C# reader accepts only v1/v2
-(CultDocumentMessagePackSerialization.cs:229) and directory v4 (Directory store :452).
-Main's TS, Rust and Python readers accept only v1 (store-format.ts `isV1Snapshot`, lib.rs:1274,
-stores.py:192). Probe on Yggdrasil at 5b5d8573 plus C2a's `v3-base.msgpack` (job
-`gate1.log`): 4/4 pass. The single file is refused naming v3, and a later flush leaves it
-byte-identical. A v5-stamped directory store is refused naming v5, and its 4 files are
-byte-identical after a later add and flush. **The pin:** C2a already ships
-`tests/vectors/document-variants-c2a/old-reader-refusal.sh`, which stages an old revision
-plus probes on a scratch ref and runs them per runtime. The land cut sets its
-`OLD_READER_REV` default to the tag `cultlib-unity-v2.0.0`. It also adds the never-rewritten
-assertion and the v5 directory case to the C# probe, and runs all four runtimes at the
-tag. If the tag is absent, the land waits for it. The tag, not a package, is the pin: the tag's
-tree holds every runtime's released reader.
-
-*Outside C2a's reach (release session):* in 2.0, `CultMesh.WriteSingleFileDocument`/
-`WriteSingleFileDocumentPayload` (CultMeshSingleFileDocuments.cs:211-245 at 7a8933b0) build
-a fresh one-record v1 snapshot and replace the file without reading it. A 2.0 Mesh write
-to a C2a v3 path therefore discards it whole, ids and other records included, and no header
-gate can stop a writer that never reads. C2a's version reads under the lock and refuses.
-Fix it in 2.0.0 before tagging, or record it.
-
-**5. Consumers.** Aetheria pins a CultLib revision (`VerifyCultLibRevision`) and Unity tags.
-Ghostlight, Eve's Rust crates, Huginn and the Brokkr daemon pin cultcache-rs by git rev.
-None of them moves when main moves. Two C# consumers build against an unpinned sibling
-`..\CultLib` checkout: Eve `GameCult.Eve.Surface.csproj:16` and Brokkr's three csprojs.
-Eve.Surface has `[MessagePackObject]` element arrays with no `[CultElementId]`
-(`EveAssetCatalogEntry[]`, `EveEntitySoaBuffer[]`, `EveInputActionDocument[]`,
-`IReadOnlyList<EveCommandTemplate>`, 0 ids in the repo), so C2a registration refuses its
-documents as soon as the checkout pulls the land. Grep finds no object lists in Brokkr's
-`[CultDocument]` files (not build-verified). Removed C2a API (`Options`, `AsSchemaAlias`) is
-unused by Eve and Brokkr. Fork: `variants:question:unpinned-consumers-at-land`.

-## Classification
-
-| Item | Class | Why |
-|---|---|---|
-| c2a-format-version-gate | **a** | The gate test above. No new header: v3/v5 already refuse. |
-| slot-reuse-contract-doc | **a** | The ruled consequence of the write set C2a lands. One paragraph in cultcache-schema-compatibility.md, absent at a5c7954e (grep). |
-| foreign-ids-under-v1-header | **b** | Obsoleted by fb065f0d (write-time `CopiedHoldIds`, after the finding) for every C# writer with the type. The residual (non-C# or opaque writers) is what `non-csharp-writers-mark-ids-2` ruled to carry, and the contract states it (persistence-format.md:434-439). The gate changes neither side, so no fork remains. Resolve as Superseded by that ruling. |
-| custom-resolver-element-ids | **b** | Fixed by b091d21f (19:52Z, after the 18:27Z follow-up): `ListElementsClaimedByAResolverAreRefused`, `AResolverClaimingTheListTypeOfAnObjectListIsRefused`. s6 holds on the claim loop. |
-| codec-door-proven-mismatch | **b** | Done in h6 57fdf70c (s6 `only-proven-mismatch` Holds; Geometry 76/0). |
-| consumer-element-id-sweep-r2 | **c** | Each repo's sweep is its own work (q3). Only the unpinned trackers matter at land, and that is the question below. Aetheria bumps a pin on purpose (C4). |
-| schema-discovery-holder-recogniser | **c** | `TryGetDictionaryRefTypes` is identical on main (CultCache.cs:1288). It describes record-ref dictionaries and is not on the id path. Changing it moves schema hashes, which is its own epoch event. |
-| copy-check-memo | **c** | Performance only (about 3x flush on unmarked stores of 20k records). Correct as is. |
-| string-key-field-and-shadow-pins | **c** | No wrong behaviour at 64ec14f9. These are test pins and may ride the land cut if Hands touches the file. |
-| declared-range-gate-own-version, range-check-in-ci | **c** | The script exists only on C2a and runs in no CI. It guards a TS publish, not a merge. Fix both before the first TS release from main after the land. |
-| s6 Unproven: Unity/IL2CPP identity, other MessagePack versions | **c** | The merge reaches no Unity build. Unity sees C2a only at the 3.0.0 tag, so measure it in the Unity release cut (operator Unity check, C3). |
-| multi-store-commit-atomicity, store-replace-cut, reader-refuses-duplicate-keys, soft-flush-all-runtimes, writer-dangling-link-tolerance, unique-index-cut, py-shared-write-lock, rust-lock-open-waits, ts-lock-test-hardening, c0/legacy/directory vectors, culture-test, wire-id-cuts, remaining-variant-cuts, golden-path, paged store | **c** | None says "before land". Each is pre-existing on main or C2a-independent. None lets a released reader strip ids or corrupt a C2a store. |
-
-## The land cut's shape (transcribe once the question is ruled)
-
-- **Base.** Merge main at or after the `cultlib-unity-v2.0.0` tag into `hands/variants-c2a`.
-  Versions stay main's. CHANGELOGs get Unreleased entries, and the Unity entry says major.
-- **Deletes and collapses.** Delete `PersistedSchemaId`, `PersistedIdentity`,
-  `CultStoredDocument.MarkWritten` and `CacheBackingStore.MarkWritten` (main, about 60 lines),
-  and the store-composition contract's MarkWritten paragraph. C2a's `StoredVersion`/`Wrote`
-  is the one owner. In TS, delete C2a's header handling in
-  single-file-messagepack-backing-store.ts and move it into store-file.ts. In Rust, C2a's v3
-  decode goes through the grown decoder.
-- **Adds.** Retarget old-reader-refusal.sh to the tag. Add the C# probe's never-rewritten
-  assertion and the v5 directory case (as in gate1.log). Add the slot-reuse paragraph.
-  Port main's ConditionalCommitTests to the version identity.
-- **Verification.** Full suites: Caching, Mesh, Networking, Geometry, WebSockets,
-  ConsumerBuild, InteropPeer, cultcache-ts/-rs/-py, cultnet-ts and cultmesh-ts, all on
-  Yggdrasil. Run old-reader-refusal.sh for all four runtimes at the tag, and it must refuse.
-  Negative greps over the merged tree: `PersistedSchemaId|MarkWritten`, conflict markers.
-  Mutation: drop the v3/v5 stamp in `HeaderFor` and the gate probe must fail.
-- **Estimate.** About 950 conflict lines resolved. Net -60 to -150 from the identity
-  collapse and TS de-duplication, +80 to +120 tests and docs. One Hands pass of 100-150
-  calls, then one Soul pass.
-- **Precondition (question).** Eve.Surface, and Brokkr if confirmed, are pinned or swept
-  before the merge reaches main.
-
-## Store gate: attachment is the attach's hold (store-gate-one-owner r2)
-
-Spec `variants:cut_spec:cut-store-gate-one-owner.r2` (base ec94ab98), question
-`variants:question:pulled-variant-codec`. It closes Soul s3's
-`attach-window-cacheless-write` (Medium) and `codec-loan-pinned-by-reflection` (Low).
-
-**Facts (source reads at ec94ab98 and a probe, 2026-10-25).**
-
-- The window. AddBackingStore holds the cache's gate, then the store's gate through
-  `InStoreHold`, lends the registry and codec, sets `Loaded`, adds the store to `_stores`,
-  pulls, and only then sets `store.Cache` (CultCache.cs 2268-2312). `InStoreHold` lets any
-  call on the same store's gate re-enter it (2825-2831). So a journal the pull's Admit runs
-  on the attaching thread can call `store.WriteDocument`: `Gate(cacheless)` guesses null,
-  re-enters the store's gate, finds `Cache == null` and runs the write, and its `finally`
-  calls `UseRegistry(null, null)` (Soul s3 P1, full1.log lines 49-53). Other threads are not
-  in the window: they queue on the store's gate and see either the published cache or a
-  store that the failed attach put back.
-- The codec loan has no reader on the attach path. A pulled variant's codec is read only
-  by `CultStoredDocument.HoldsIds` (543-557). Header decisions read `HoldsIds` only on
-  staged entries (single-file 4318, 4447 and 4472; directory store 362), and a staged entry
-  is always the document the cache pushed (`Push` sets `Entries[key] = entry`, 4211-4215).
-  A single-file `PullAll` returns without loading while the store is dirty (4157-4159), so
-  a pulled copy is never staged. A refused write unstages its keys before it adopts the
-  reload. The directory store refuses variants (ruling `q6-directory-and-cultnet-refuse`;
-  DirectoryMessagePackBackingStore.cs 139-144 and 642-643). Admit re-resolves every pulled
-  variant with the cache's codec (CultCache.cs 3259). Soul's N4 mutant (the attach lends
-  no codec) was caught only by the reflection test, and h4's M2 only by a bare-store test
-  that sets `Loaded` and calls `UseRegistry` by hand.
-- Probe (scratch clone `imagination-store-gate-r2/clone`, commits 4663934e and c099b9e8 on
-  ec94ab98; Yggdrasil t1.log, t2.log and t3.log; 2026-10-25 around 20:50 CEST). The
-  probe did three things. `InStoreHold` refuses a cacheless call that re-enters the same
-  store's gate. The `_codec` field and the two-argument `UseRegistry` are deleted. The pull
-  builds variants with a null codec. Results:
-  - Mesh is 342/0/4.
-  - In the Caching suite, the only failures were two probe tests, both from authoring
-    errors: a key `AddAsync` minted, and an element id that was not 12 hex characters.
-    No existing test failed, `UserCodeInACachelessCallMayCallItsOwnStore` included.
-  - Soul's P1 as a test: the journal's write is refused with the new message. The attach
-    keeps its registry and the file holds only `a`. After the attach, a cache write, a
-    flush and `store.PullAll()` all succeed.
-  - A cacheless write nested in another on the same store is refused, the outer write
-    fails, and no file is written.
-  - Through a real attach, a store holding a name-override variant flushes an unrelated
-    commit with a `cultcache.store.v2` header. With no codec loan, the pulled copy does not
-    mark the store.
-  - Mutant `return cacheless` changed to `return false`, which is ec94ab98's behaviour,
-    fails both new gate tests. In that mutant the nested write succeeds and the file exists.
-
-**Rationale.**
-
-- Attachment has one fact again. While the attach runs, the store's gate is the attach's
-  hold, and `Cache` is published when that hold ends. A cacheless write is a write the
-  store owns outright, so it must be the outermost hold of its store's gate. One more
-  argument to the existing owner of per-thread gate facts (`InStoreHold`) refuses it. No
-  field mirrors `Cache`, and `Loaded` and `_registry` are not read. Precedent:
-  `ConcurrentHashMap.computeIfAbsent` refuses a mapping function that updates the same
-  map with `IllegalStateException("Recursive update")` since Java 9. That is from
-  memory, not fetched this pass; the 2026-10-23 prior-art note covers the documented
-  restriction in its counter-positions. Non-cacheless store calls from user code still
-  re-enter: `UserCodeInACachelessCallMayCallItsOwnStore` stays green.
-- The late publish stays. It is what bounds `Gate` at two passes (s2's finding). Publishing
-  early would bring back the failure-rate-bounded retry.
-- The codec loan goes: it is a value nothing on the attach path reads. A pulled variant
-  carries no codec and counts as holding ids (the documented conservative answer), and
-  the cache's resolved copy is what any header decision sees. This reverses the codec
-  half of Defaulted ruling `late-publish-needs-attach-codec`, so it goes to Self as
-  `variants:question:pulled-variant-codec`. The spec is written for the recommended option.
-- Scar check: `git log -S` over CultCache.cs for `reentrant`, `outermost` and `_attaching`
-  finds nothing. `Cache?.Codec` appears in 1468a83a (h4) and 619e089f only. No earlier
-  re-entry refusal was built and deleted.
-- Behaviour change, stated in the CHANGELOG: a cacheless write made from user code that
-  another cacheless write of the same store runs used to succeed, and its `finally` took
-  the outer call's registry. It is now refused.
-
-## Store gate: Cache is the one attachment fact (store-gate-one-owner r3)
-
-Spec `variants:cut_spec:cut-store-gate-one-owner.r3` (base 0fa836cb), superseding r2. It
-closes Soul s4's `attach-window-held-store-writes` (Medium), `cacheless-refusal-order-unpinned`
-(Low) and `interop-consumer-suite-unrun` (Low). This is the third time the attach window has
-beaten the rule (s3 from the cacheless side, s4 from the held side), so r3 moves the
-decision instead of patching the next entry point.
-
-**Facts: every entry point that reads or decides attachment, at 0fa836cb.** Source reads of
-CultCache.cs, DirectoryMessagePackBackingStore.cs and CultMeshSingleFileDocuments.cs. The
-window column is a journal on the attaching thread, through a real attach of a store holding
-`a`. Probe: scratch clone `imagination-store-gate-r3/clone`, commit b2330b6d (test R3Probes),
-Yggdrasil `probe-base.log`, 2026-10-25 around 23:00 CEST. "Disagree" means that after the
-attach, a commit of `later` and a flush, the attaching cache holds `a,later` and a fresh cache
-over the same file reads something else.
-
-| Entry point (line) | Fact it reads | In the attach window at 0fa836cb |
-| --- | --- | --- |
-| Single-file `PullAll` (4156) | `Gate`: `Cache` guessed unlocked, then re-read under the re-entered store gate | Runs as detached; its `Loaded` re-enters the cache and is refused as a journal write. Agrees. |
-| Single-file `Push` (4212) | same | Runs as detached and stages `b`. Disagree: fresh reads `a,b,later`. |
-| Single-file `Delete` (4223) | same | Runs as detached and stages a removal the cache never made (dirty after the attach). |
-| Single-file `PushAll` (4239), and `Dispose` (3722) through it | same, then in-body `Cache == null` (4531, 4543, 4588, 4603, 4611, 4661) | Runs as a cacheless writer. Push then PushAll writes `b` to the file inside the attach (disagree). Delete then PushAll is refused with the cacheless writer's text. On a variant store it is refused as "a writer with no CultCache" (Soul s4). |
-| Single-file `CommitBatch` (4256) | same | Runs as detached and commits `b`. Disagree. |
-| Single-file `JudgeChecks` (4568), `RefuseRemovalOfUndeclared` and `StageChecks` (4558, 3915) | same | Run as detached. Agree in the probe, but under the wrong gate's rules. |
-| Single-file `ReadStoreSnapshot` (4687) | same | Runs as detached and reads the file. |
-| `WriteRecord` (4342), `WriteDocument` (4366) | `InStoreHold`'s per-thread hold (cacheless re-entry), before `Cache` | Refused with the re-entry text (h5). Agree. |
-| Directory `PullAll` (48) | `Gate`, as above | Refused as a journal write. Agree. |
-| Directory `Push` (147), `Delete` (160), `CommitBatch` (172) | same | Run as detached. Disagree: fresh reads `a,b,later` after Push or CommitBatch, and `later` after Delete. |
-| Directory `PushAll` (235) | same | Runs as detached. Push then PushAll and Delete then PushAll disagree. |
-| Directory `JudgeChecks` (269), `RefuseRemovalOfUndeclared` (259) | same | Run as detached. Agree. |
-| In-body reads: `StoredAtOver` clock (4028), refusal text and `DurableAt` (4531, 4543), declares and cacheless refusal (4588, 4603, 4611), `Wrote` (4661) | `Cache`, under the gate `Gate` chose | On the attaching thread they read null while the thread holds the cache's gate, so a held call runs as a cacheless writer. |
-| `AddBackingStore` (2259-2314) | writes `Cache` under both gates, after the pull | The window's author: the store is attached for the pull (registry lent, `Loaded` set, in `_stores`) while `Cache` is null. |
-| Mesh `CultMeshSingleFileDocuments` writes and reads (99, 143, 174, 226) | none of the attached store's | `StoreAt` (239) builds a new store per call, so they never touch an attached store object. A file it shares with an attached store is the file lock's and the write set's business. |
-| `IsDirty`, `HasStagedChecks`, `ForeignRecords`, `LastSchemaMigrationReports`, `HeaderFor`, `HeaderForWrite` | none | Ungated values or static decisions. They read no attachment fact. |
-
-So during an attach, cacheless entry points decide attachment from the hold, and every held
-entry point, plus every in-body read, decides it from `Cache`, which is still null. These are
-two facts.
-
-**Probe of the chosen shape** (commit 4695390c on b2330b6d; `proto-full.log`). `AddBackingStore`
-publishes `Cache` before the pull and takes it back in the same hold if the pull fails. `Gate`
-becomes straight-line code: guess, then the store's gate, where `Cache` is settled, then the
-settled cache's gate. Results:
-
-- All 21 probe cases are refused. The cacheless writes get the re-entry text and every other
-  case gets "A journal entered the cache it journals". After the flush, the attaching cache
-  and a fresh cache both read `a,later`.
-- Caching: the only failures are the two tests that pin the late publish:
-  `AnAttachLendsTheRegistryAndPublishesTheCacheAfterThePull` (asserts no cache during the
-  pull) and `ACallWhoseGateChangesTwiceUnderItThrowsInsteadOfLooping` (asserts the old message
-  text; the tampering reader still throws). The churn, queued-reader and failed-attach tests
-  pass unchanged.
-- Mesh and Networking are green.
-- The cultcache-ts suite, which builds and drives the C# InteropPeer, passes on this shape:
-  175 tests, 171 pass, 0 fail, 4 skipped. The C#, Rust and Python interop tests ran, the C#
-  edit-in-place one included (`proto-ts2.log`, commit f5f02053). Recipe `clone/r3ts.sh`:
-  image node:24-bookworm, apt python3-msgpack, dotnet-install for 10.0, rustup minimal.
-
-**Shapes weighed (rationale).**
-
-- (a) Publish `Cache` before the pull, as a616431e did. Chosen. What s2 found was not that an
-  early publish is unbounded. It was that `Gate` re-read `Cache` *unlocked* after a stale
-  guess, so a churn of failing attaches could hand it a new stale guess every pass. The fix is
-  where `Gate` reads on its second step. Under the store's gate, `Cache` is settled: an attach
-  publishes and takes it back inside one hold of that gate, and no other thread can hold that
-  gate during the attach. A settled cache is permanent, because there is no detach. So `Gate`
-  needs at most three acquisitions, with no loop and no counter: the guess's gate, the store's
-  gate, and then the settled cache's gate, which cannot miss. This deletes a fact rather than
-  reconciling two. During the attach the store *is* attached, so every entry point, cacheless
-  or held, and every in-body read sees one answer. A journal's call is then refused by the rule
-  journals already have (AddJournal: "any hold on this cache while a journal runs throws"),
-  exactly as it is after the attach. Prior art: `ConcurrentHashMap.computeIfAbsent` installs a
-  ReservationNode in the bin *before* running the mapping function, so a recursive update on
-  the same thread finds the owner and throws, and on failure the reservation is removed (see
-  `docs/research/2026-10-23-store-lock-user-code-prior-art.md` item 4 on main: the re-check
-  after locking, and the ReservationNode on the empty-bin path). The validate-after-acquire in
-  `Gate` is the same item.
-- (b) Keep the late publish and make the attach's hold the one fact for every entry point.
-  Rejected. `InStoreHold` knows that this thread holds the store's gate, not *whose* hold it is.
-  Refusing every same-store re-entry kills `UserCodeInACachelessCallMayCallItsOwnStore` (r2's
-  R5), so (b) needs an "attaching" marker beside `Cache`. That is the second fact that s3 and
-  s4 rule out, plus every in-body `Cache == null` read would need to consult it as well.
-- (c) Run no user code on the attaching thread under the store's hold during a pull: defer the
-  pull's journals to after the hold (open calls). Rejected as insufficient on its own. Getters
-  and constructors still run during the pull's decode, so the window stays open to any user
-  code that is not a journal. It also moves journal timing, which is a documented contract
-  ("right after an admission is applied").
-- Scar check: `git log -S` over CultCache.cs finds `store.Cache = null` and `MaxStaleGuesses`
-  only in ba658965 and 1468a83a. The early publish was not removed for a correctness reason of
-  its own: 1468a83a removed it to bound `Gate` and to lend the codec, and the codec loan is gone
-  (`pulled-variant-codec`). No settled read under the store's gate was built before. The
-  precedent recipe (no root filter) finds no same decision.
-- Not a product fork. A journal's store call during an attach now throws, as it already does
-  after the attach. Cacheless writes on the attaching thread stay refused, with the same text.
-  Getters and constructors during the pull see an attached store, as they do during any held
-  call. It changes the late-publish clause of Defaulted ruling `variants:ruling:pulled-variant-codec`,
-  so Self defaults a superseding ruling (recommended label `cache-published-for-the-pull`)
-  before dispatch.
-- Residual, not in r3. `Push`, `Delete`, `PushAll` and `CommitBatch` are public, so user code
-  that is not a journal (another thread, or a getter during any held call) can stage records
-  behind an attached store's cache. Soul s4 shows this with `other-thread-push`: file `a,b`,
-  cache `a`. That is true before, during and after an attach, so it is not the window's
-  two-fact problem. Closing it changes public API (a store's writes taken only from its
-  cache), so it is a follow-up and an operator question for Self, not part of this cut.
-
-## Body facts: claimant-one-owner r2 (Imagination, 2026-10-27, base fc74cf6f)
-
-Why a revision: Soul beat the same rule three times (s1 claimant choice, s2 compatible ids, s3 shape). Each time a
-cacheless write lent a registry let the registry's entry for the written schema id decide ownership beside the entry
-the caller passed. Two descriptions of one type reached `Owns`; each fix (h2 schema-id compare, h3 subset of compatible
-ids) compared one more facet of the two and left the rest open. r2 removes the second description from the lookup.
-
-### Where the two descriptions met (source read, fc74cf6f)
-
-- `OwnsOnDisk` cacheless arm (`CultCache.cs:4725-4740`): with a lent registry it called
-  `lent.Owns(id, catalog, declared, written)`, whose lookup is the registry's `_indexes` and whose `entryOf` is
-  `descriptor.ToCatalogEntry()` (`:824-825`). The claimant for the written schema id was the registry's descriptor,
-  so `ReadsWhole(persisted, claimantEntry)` (`:848`) judged shape against the registry's entry, and the claimant
-  precedence (`:756-806`) walked the registry's compatible ids. `written` (`:4734-4736`) then compared the two entries
-  by schema id plus a subset of compatible ids.
-- `WriteDocument` (`:4495-4524`) takes its entry from the registry (`resolvedRegistry.GetRequired<TDocument>().ToCatalogEntry()`),
-  so its two descriptions are always identical. Only `WriteRecord(record, catalogEntry, holdsIds, registry)` (`:4471`) can
-  pass an entry that disagrees with the registry's entry for the same id.
-- `CopiedHoldIds` (`:4600-4630`) also reads `AttachedRegistry`, to decide the v3 header from copied records. It is a
-  positive-only header decision, not ownership, and out of this cut.
-
-### Consumer audit (2026-10-27)
-
-- `WriteRecord` and `WriteDocument` are new in the Unreleased 3.0.0 entry; `main` has neither (`git show main:src/GameCult.Caching/CultCache.cs`).
-- Per-repo `rg` over every git repo directly under `F:\Projects` for `.WriteRecord(`, `.WriteDocument(`, `WriteSingleFileDocument`
-  (Library, obj, bin, PackageCache excluded): hits only in CultLib and in vendored CultLib copies under Heimdall and StreamPixels
-  (`vendor\CultLib`, older pins without these methods). No consumer outside CultLib calls either method.
-- Inside CultLib at fc74cf6f: Mesh `WriteSingleFileDocument` calls `WriteDocument(key, document, storedAt, registry)`;
-  Mesh's raw-payload path calls `WriteRecord(..., registry: null)` (`CultMeshSingleFileDocuments.cs:129, 226`). The only
-  `WriteRecord` calls with a registry are tests: `CachelessSingleFileTests.cs:453, 660` (a registry `{IdDeck}` that does
-  not hold the written entry `One` at all, used for the copied-record header), `RestampOnWriteTests.cs:595, 599`, and
-  Soul's probes. Packages: no TS, Python or Rust counterpart takes a registry (cultnet-rs `write_record` is an example helper).
-- Consequence: the registry's documented role in `WriteRecord` is to describe the other records in the store. A shape
-  that derives the written entry from the registry (or refuses an entry the registry does not hold) breaks
-  `CachelessSingleFileTests.cs:660` and removes that role.
-
-### Candidate shapes weighed
-
-| Shape | One description? | Public API | Kills s2/s3 | Cost |
-|---|---|---|---|---|
-| A. Lent registry's entry decides; refuse a passed entry that disagrees | yes, after a door check | signature kept; new refusal | yes | an equality check over a redundant parameter; breaks the registry-describes-others use (`:660`) when the registry lacks the written type unless it falls back to the passed entry, which is two descriptions again |
-| B. Passed entry is the only description of its schema id; the registry supplies other types only | yes, by construction | signature kept; doc only | yes (probed) | one lookup class gains the registry; one registry overload deleted |
-| C. Overloads: `WriteRecord(record, catalogEntry, holdsIds)` and `WriteRecord(record, registry, holdsIds)` | yes, by type | changes a 3.0.0 signature | yes | loses the registry-describes-others use |
-| D. Delete `WriteRecord`'s registry parameter | yes | changes a 3.0.0 signature | yes | loses the copied-record header decision for raw writes |
-
-Picked B. It is the only shape that keeps every documented use of the registry, needs no public signature change,
-and deletes the comparison instead of extending it. It is ordinary scoping (an inner binding shadows the outer one
-for its name), applied to schema ids.
-
-### Probes (Starfire, local filtered runs, 2026-10-27)
-
-Scratch clone of fc74cf6f at `<scratchpad>/imagination-claimant-r2/clone`, Soul's `SoulClaimantProbe.cs`,
-`SoulClaimant2Probe.cs`, `SoulClaimant3Probe.cs` copied into `tests/GameCult.Caching.Tests`.
-
-Base fc74cf6f (`probe-base.log`):
-- P7 (registry {N lists own, A, B}; passed entry N with the list varied; record k under O, named like N): lent R / no
-  registry C for rows b, b2, e, g, h, k, l, l2; lent C for a, c, d, f, i, j. Confirms `subset-refuses-own-drift`.
-- P9 (registry {NW: Name, Value, Colour}; passed NW minus Colour): lent C (restamped, Colour lost), no registry R.
-  Confirms `lent-shape-widens-passed-entry`.
-- P6 (bare X1 entry, registry {X1} listing OX, record under OX): lent R, no registry R, cache C. h3 closed the id axis.
-- P4: 12 states x 8 registries, violations=0. P1d: a cache {N,L} commits N over L's listed old id (`cache-replaces-other-types-record`).
-
-Prototype B (scratch commit 349ea3f3 on the clone, not for landing; `probe-protoB2.log`): `CatalogEntryLookup` takes
-the written entries and an optional registry and drops every registry descriptor whose schema id a written entry has;
-the registry's `Owns(schemaId, catalog, declared, mayClaim)` overload is deleted; the cacheless arm always asks
-`CultDocumentRegistry.Owns(id, catalog, declared, new CatalogEntryLookup(writes, AttachedRegistry), entry => entry,
-claimant => writes has claimant's schema id)`.
-- P7: lent == no registry on all 14 rows (all C).
-- P9: lent R, no registry R, wide entry C.
-- P6: unchanged (R, R, C). P4: identical table to base, violations=0. P1a-f, P2a-d: identical to base.
-- `RestampOnWriteTests`, `CachelessSingleFileTests` and the probes: 139/139 passed locally.
-- Yggdrasil, 349ea3f3, `ygg-protoB-full.log`: GameCult.Caching.Tests 1180 passed / 0 failed / 2 skipped;
-  GameCult.Mesh.Tests 342 / 0 / 4.
-
-Negative greps, each tested at fc74cf6f (each matches there, and none may match after the cut, src and tests):
-`claimant.CompatibleSchemaIds.All(` (1, the subset), `lent.Owns(` (1), `Func<CultSchemaCatalogEntry, bool> mayClaim) =>`
-(1, the deleted overload), `CatalogEntryLookup(writes)` (3, one-argument construction). CHANGELOG and docs:
-`never widens what the passed entry declares` (1), `with no compatible id the passed entry does not list` (1).
-
-### Not settled by r2
-
-- `cache-replaces-other-types-record` (s2, PreExisting, cache arm): r2 touches only the cacheless lookup, so it does
-  not settle whether a cache may replace another registered type's record at a shared key.
-- Whether a registry-less `WriteDocument` should consult `CultDocumentRegistry.Shared` for claimants at all (s1
-  `shared-decides-registryless-write`, closed Fixed by documentation in h2). r2 keeps today's answer.
-- `variants:finding:cut-restamp-on-write.s2.cacheless-inverts-registry-claimant` is still in force although r1 was
-  mapped to close it; Self should close or re-triage it after r2's Soul pass.

-
-### Body facts
-
-- A1. The generator does not discover `CultRecordRefFormatter<T>`. For a generic type it does not know, it collects
-  the type's definition as an object and names the formatter it would generate, `<Type>Formatter<T>`, nested in
-  `GeneratedMessagePackResolver`. For a type from another assembly it then generates nothing, so the resolver names
-  `GeneratedMessagePackResolver.GameCult.Caching.CultRecordRefFormatter<T>`, which does not exist (CS0426). The match
-  with our formatter's name is a coincidence. Evidence (job1): `[ExcludeFormatterFromSourceGeneratedResolver]` on the
-  formatter, and an `internal` formatter, both still fail G, H and B with the same line. Upstream issue
-  MessagePack-CSharp#2133 (open, no maintainer reply) reports the same failure for any open-generic type with a
-  formatter in another package.
-- A2. Consumer MessagePack 3.1.12, the newest stable, fails G, H and B the same way (job1). Upgrading does not fix it.
-- A3. `[MessagePackFormatter(typeof(CultRecordRefFormatter<>))]` on the `CultRecordRef<T>` struct stops the
-  generator naming a formatter for it (the mangled line is gone), but the generator then reports `MsgPack006` (error)
-  in every consumer: it checks `typeof(X<>)`'s interfaces, which an unbound generic does not list. Adding the
-  non-generic `IMessagePackFormatter` marker to the formatter does not help (job2 `ta2`). With `MsgPack006`
-  suppressed by the consumer, G, H and B build and run (job2). Rejected: it needs the formatter moved into
-  `GameCult.Caching`, which then needs the whole `MessagePack` package instead of `MessagePack.Annotations`, and every
-  generator consumer still has to suppress an error.
-- A4. `[assembly: MessagePackAssumedFormattable(typeof(CultRecordRef<>))]` in the consumer assembly fixes G, H and B
-  with no library change (job2 `base@ASSUMED`). The generator stops collecting `CultRecordRef<T>`; the generated
-  document formatter asks the resolver, and `CultDocumentResolver` serves the ref. This is the attribute MessagePack
-  documents for "a formatter added through a custom resolver at runtime". The same attribute as an MSBuild
-  `AssemblyAttribute` item in the consumer project (`_Parameter1_IsLiteral`), which is what a package's
-  `buildTransitive` targets injects, does the same (job3 MG, MH, MB). The attribute declared in the library assembly
-  does not reach the consumer's generator (job4 LIBATTR: CS0426).
-- A5. Generated and dynamic formatters write the same bytes. RefDoc (B) payload is `93A172A17081A170CA3F000000` from
-  the Reflection.Emit fallback with no generator (job3 BASE) and from the generated formatter (job3 MB). The document
-  formatter is `GeneratedMessagePackResolver+Probe+RefDocFormatter` (`dynamic=False`); the ref formatter is the
-  library's `CultRecordRefFormatter<PlainDoc>` through `CultDocumentResolver`.
-- A6. NativeAOT (`PublishAot`, probe assembly rooted, linux-x64): G round-trips (payload, upsert, flush, reopen) with
-  payload `92A172A170`, identical to JIT (job4 G0). B fails, in C2a code, not in the generator path: upsert fails in
-  `CultElementIds.MapEntries`, whose `MakeGenericMethod(key, value)` has no native code for a struct key (job4 B0). With
-  that walk reading the map through non-generic `IDictionary` instead, upsert passes under AOT and JIT is unchanged
-  (job5 B1), but the payload and flush still throw `TargetInvocationException` from a second reflective call on the
-  serialize path. By source read the candidate is `ResolverClaim`'s `GetFormatterMethod.MakeGenericMethod(type)`
-  (`CultDocumentMessagePackSerialization.cs:84`), not proven. Both are runtime reflection over element-id paths, which is
-  AOT cut 3's ground, so cut 1 proves AOT on the member shape and leaves the key shape's AOT round trip to cut 3.
-- A7. `GameCult.Geometry` already runs the generator (it references `MessagePack` directly) and carries the per-member
-  workaround on three members (`CultGeometryDocuments.cs:164,239,328`). Under A4 those attributes are redundant.
-
-### Shape the cut lands, and why
-
-`GameCult.Caching.MessagePack` ships `buildTransitive/GameCult.Caching.MessagePack.targets`, which adds the A4 assembly
-attribute to every project that consumes the package. NuGet consumers need no line of their own, which is what a
-consumer expects from a library whose type breaks the generator. Unity consumers and in-repo `ProjectReference`
-consumers do not get `buildTransitive`: Unity consumers write the one attribute line (README), and in-repo consumers
-import the targets file, so they exercise the file that ships. The attribute type comes from `MessagePack.Annotations`,
-which `GameCult.Caching` already brings, so the injection compiles in a consumer with or without the generator. Wire
-bytes do not change: no formatter changes, only which code path asks for it (A5).
-
-Rejected: a type-level formatter attribute (A3); excluding or hiding the formatter (A1); upgrading MessagePack (A2);
-declaring the attribute in the library (A4); keeping per-member attributes, which cannot reach dictionary keys.

-Campaign `cultmesh-garden-path`, stage 1 (server-authoritative garden path for the
-orbs .io game). Target: `docs/cultmesh-garden-path-target.md` (typed as
-`cultmesh-garden-path:target:r2`). Rulings, questions and follow-ups are documents
-in the mind; this page holds the model page, body facts and the stage 1 cut lines.

-Written by Imagination (`imagination-gp-0b`, session `self-2026-10-27-eureka`)
-against CultLib `d1bf21b3`. Refreshed by `imagination-gp-stage1` (session
-`self-2026-10-27c-eureka`) against `51ca81a1`: every fork the page waited on is
-ruled, and the cells below carry the rulings.
-
-## Model page
-
-One row per kind. "Store" says where it lives: a CultCache document in the room's
-store, or transient per-tick data that never enters a store. Proposed values are
-marked as such; they are the design this page offers for the cuts, not landed
-behaviour. A cell that waits on an operator question names it.
-
-The governing split, from `state-is-cultcache` and the CultCache scope restraint:
-every value that crosses a boundary is CultCache-encoded (one serialisation model,
-no JSON), but only state that outlives a tick is a record in a store. Inputs, ticks
-and snapshots are typed CultNet message payloads, not store records. The store
-receives exactly one write set per tick (ruled `tick-state-commit`: tick-batch).
-
-| Kind | Store | Identity (what names it) | Lifecycle (what happens to it) | Authority (who decides; forbidden writers) |
-|---|---|---|---|---|
-| **Game definition** (documents, systems, authority declaration, tick rate) | Proposed: one CultCache document per server process (`gamecult.mesh.game_definition`), read-only to everyone but the server's startup. | Game id string from code (`"orbs"`), namespaced by Verse id. The id alone is not injective (two builds share it), so proposed identity is `(game id, definition hash)`, the hash derived from the lowered definition: document schema ids and versions, system ids, order and marks (`[Predicted]`, later `[Adjudicable]`), tick rate, authority declaration. Schema ids (`orbs.player`) are global strings; the game prefix is convention, not enforced (body fact F9). | Created at server startup from code; never revised at runtime; a new build supersedes it with a new hash. Clients carry their own compiled hash (C# in wasm, ruling `browser-sim-runtime`) and are refused at join on mismatch. A declaration a mode cannot honour is refused at startup (`modes-do-not-leak`). Never replayed. | The game's code, through the builder, at startup; the runtime validates. Forbidden: clients, any runtime mutation, Odin (Odin may read and index it, never write it). |
-| **Game document** (Player, Pellet, Shot) | CultCache documents in the room store. | `(schema id, record key)`. Today the key is a free string the caller picks; `[CultIndex] Id` in the illustration is an index, not the key. Proposed: the runtime mints keys. Player key derives from the session principal (one Player per principal per room). Spawned documents (Shot, Pellet) key on `(spawner key, tick, spawn ordinal within that tick)`, so a client's predicted spawn and the server's authoritative spawn derive the same key and reconcile instead of duplicating. That is injective as long as spawn order within a system step is deterministic for the predicting client, which the predicted system's own code gives under one runtime (C# both sides). The developer's `Id` field becomes redundant; whether to keep it as a mirror of the key is an API call for the cut, not an operator fork. | Created by a system during a tick, or by the join system (Player). Revised at most once per tick, in that tick's commit. Deleted by a system (pellet eaten) or by the game's leave system after a session ends. Across reconnect within the grace window the Player record is unchanged; only the session's connection binding moves. Across a server restart: gone (ruled `room-durability`: ephemeral; a restart is a new room epoch at tick 0). Replayed only on the client, during reconciliation; the server never replays in stage 1. | The server tick runner on the room's primary is the one writer of committed state, and systems write only through the tick's working set. Forbidden writers: client document puts through `CultNetDatabaseServer.HandlePutAsync` (today accepted from any peer, F1); `PutPredictedAsync` and `CultMeshGameSession.PredictAsync` on any networked store; game code calling database APIs; the simulation-fact committer (F7). |
-| **Player input** | Transient. A CultCache-encoded payload on a CultNet message; never a store record in stage 1. | `(session principal, input sequence)`, the sequence monotonic per session; each input also carries the tick it targets. Namespace: the room. Injective given the principal. The input type is a schema'd CultCache type, so the schema catalog publishes it like any document. | Sampled each client tick (devices read by the TS shell, handed to wasm); sent with the last few unacknowledged inputs repeated, so one loss is absorbed; buffered by the server per session against its target tick; consumed exactly once by the matching tick (proposed policy for late inputs: applied to the next tick and counted); acknowledged in the snapshot as "last processed sequence"; kept by the client until acknowledged, for replay; then discarded. Stage 4 changes this: inputs become signed, hash-chained and retained for a dispute window. | The client's principal authors the content; the tick runner decides which tick consumes it. Forbidden: server code altering input content; other clients; any input that arrives without a bound session. |
-| **Tick** | Transient counter; proposed: the last committed tick is written into the room record in each tick's batch, so a snapshot or checkpoint knows it. | `(room id, room epoch, tick number)`, the number starting at 0 when the room epoch starts. Injective with the epoch. | Advanced only by the server tick runner at the one declared rate (ruled `tick-model`: one-fixed-rate); never revised. The client estimates the server tick from snapshots and runs its predicted tick ahead by its round trip plus a buffer; on reconnect it re-syncs from the next full snapshot. | Server tick runner. Forbidden: client clocks, transport arrival time, wall-clock reads inside systems (systems receive the tick, not the time). Today no tick scheduler exists anywhere in the C# body (F6). |
-| **Predicted state and reconciliation** | Client-side only. In the browser they live in the C# wasm CultCache store; the TS renderer reads a per-frame view (ruled `browser-client-store`: wasm-owns-store). | Same `(schema id, record key)` as the authoritative document, plus the client tick it was predicted for. | Each client tick: predicted systems run over owned documents and the client's own spawns. On a snapshot for tick T acknowledging input sequence S: predicted documents are replaced by the authoritative ones at T, then inputs after S are replayed through the predicted systems up to the current client tick; predicted spawns are matched by derived key, and an unmatched one is removed once the acknowledgement passes its tick. Today `Reconciled` means "the authoritative put replaced the predicted copy" with no replay (F3); the replay loop does not exist. | Predicted state owns nothing outside the client. It is derived from the last authoritative snapshot plus unacknowledged inputs plus the predicted systems. The snapshot owns truth. Forbidden: sending predicted documents to the server; `CultNetClientAuthorityScope` in server mode (F4); the renderer writing. |
-| **Session and the player's identity** | Proposed: session membership as a small CultCache document in the room store (`gamecult.mesh.game_session`, low churn, readable by systems and present in snapshots). The connection handle is transient process state. | Principal: the fingerprint of a browser-held P-256 key, proved by signing a join challenge (ruled `player-identity`: browser-keypair). Connection: a server-minted id per transport connection (ephemeral). Logical session: `(principal, room)`, bound across reconnects. Today the client's identity is a self-asserted `runtimeId` string (browser client options; `SourceRuntimeId` on operation envelopes); CultMesh's session identity proves the server to the client and not the reverse (F5). The body still has no authenticated client principal (F5, F13); the session cut builds it. | Connect, then join (definition hash check, principal proof), then the session record is created and the join system spawns the Player. Disconnect suspends the session for a grace window; resume binds a new connection to the same session; expiry ends the session, systems see the leave, and the game's leave system removes the Player. On server restart sessions end (ruled `room-durability`). | The server's join and leave handler on the room primary decides membership; the principal proves itself by signing the join challenge. Forbidden: a client-asserted `runtimeId` as identity; transport peer address; peer catalogs. |
-| **Authority declaration and the lease it lowers to** | Declaration: inside the game definition. Lease: proposed as a CultCache document (`gamecult.mesh.authority_lease`); today a plain class in an in-memory dictionary (F2). | Declaration: per document type, `(writer, checker, arbiter)`. Lease: `LeaseId`, carrying Verse, peer, roles, shard ids, issuer, validity window, epoch and signature (`CultMeshAuthorityLease`). Namespace: the Verse. | Declaration fixed per build. At startup `Authority.Server` lowers to: the server holds a `ShardPrimary` lease on the room shard, and clients hold no write scope at all. Renewed before expiry; revocation or expiry stops the tick runner from committing; a new primary takes a new epoch. Proposed issuer in stage 1: the server's own deployment key, which clients pin through the browser trust policy, so an indie deployment needs no Odin. Odin-issued leases stay possible. | The game definition decides the declaration; the issuer issues leases; `CultMeshAuthorityResolver` decides whether a peer holds a role on a shard. Today the database's write gate (`CultNetShardDescriptor.IsPrimary`, `CultNetClientAuthorityScope`, both set from options) never consults the resolver: two authority structures (F2, F4). Proposed: the write gate is derived from lease resolution. First step (cut `remote-write-authority`): a peer's put or delete reaches the database only when `CultNetDatabaseServerOptions.RemoteWriteAuthority` grants it; none configured refuses every remote write (F1, GP1). The lease-backed grant needs an authenticated principal bound to the connection, so it follows the session cut. `CultNetClientAuthorityScope` is no longer an owner; it is derived from the declaration, and in stage 1 it is empty. |
-| **Shard / room** (stage 1: one) | `CultNetShardDescriptor` (configuration); the room's state is its CultCache store. | Room id `(Verse, game id, room name)`, for example `orbs/main`, carried as the shard id plus the shard epoch. | Created at server start (epoch 1; on restart a new epoch, ruled `room-durability`); never moved in stage 1; ended at shutdown. Join means "join the one room"; matchmaking is out of scope. Interest management is stage 5 per the target, so in stage 1 every client receives the whole room. | The runtime holding the `ShardPrimary` lease. Forbidden: a second primary; clients. |
-| **Snapshot sent to clients** | Transient. A CultNet message whose payload is CultCache-encoded documents; never stored. The server keeps per-client baselines in memory for deltas. | `(room, epoch, tick, recipient session, baseline tick)`. | Derived after a tick commit at the send rate; a delta against the recipient's last acknowledged snapshot, or a full snapshot on join and resume; carries the last processed input sequence for that session. Discarded once sent; a baseline is dropped when a newer one is acknowledged. Today the nearest things are per-record change pushes from `CultNetDatabaseSubscriptionServer` (no tick, no acknowledgement, no input sequence) and shard catch-up snapshots in `CultMeshSnapshots.cs` (F8). | The snapshot builder decides nothing; it is derived from the committed tick. Forbidden: the per-record subscription stream acting as a second game replication path. That stream stays for non-game observers. |
-| **Simulation fact / witness observation** (found) | `CultMeshSimulationFact` is a CultCache document; observations are hub memory. | `(shard, epoch, frame, subject, kind)`. | Stage 1: not used. The target replaces it at stage 4. | Today `CultMeshGameSession` serves observations by default (`ServeSimulationObservations = true`) and commits quorum facts through the primary (F7). In server mode there is no checker, so the observation server and the committer must not be wired. Forbidden writer in stage 1. |
-| **Shard mutation log entry** (found) | `CultNetDatabase` in-memory `SortedList` per shard, plus an optional durable store. | `(shard id, sequence)`. | Today every primary write appends one entry, and the in-memory list is never trimmed (F10). Per-record writes at tick rate would grow it without bound. In stage 1 the tick's write set either bypasses the per-record log or lands as one bounded entry per tick. Ruled: the tick's write set lands as one batch per tick (`tick-state-commit`), in memory (`room-durability`); the bounded per-tick entry is the tick-runner cut's to specify. | `CultNetDatabase` on the primary. Forbidden: per-system-write appends from the tick runner. |

-## Body facts
-
-All are source reads at CultLib `d1bf21b3` on 2026-10-27 by `imagination-gp-0b`. No
-runtime probe was run in this pass. Each fact names the read that would falsify it.
-
-- **F1. The primary applies any peer's document put.** `CultNetDatabaseServer.HandlePutAsync(message, peer)` (`src/GameCult.Networking/CultNetDatabaseServer.cs:307`) calls `ApplyPutAsync(message)` (`CultNetDatabase.cs:1022`), which checks only that this runtime is primary for the shard and the epoch matches (`EnsurePrimary`, `:2003`). `peer` is used only to send errors. Any connected client can overwrite any game document on the server.
-- **F2. Leases are not typed state and do not gate writes.** `CultMeshAuthorityLease` is a plain class (no `[CultDocument]`); `CultMeshAuthorityLeaseCatalog` is a `Dictionary` (`CultMeshAuthority.cs:242`). The only `[CultDocument]` types in `GameCult.Mesh` are body publication, CDN chunk and manifest, content transfer state, discovery state, entity prefab package and simulation fact. `GameCult.Networking` (the database) references no lease type; the one Networking file naming `Lease` is `CultNetSchemaMessages.cs`.
-- **F3. Reconciliation is replacement, not replay.** `CultNetDatabase.cs:1247-1252`: a predicted put records a prediction key; the next non-predicting write to that key turns the change into `Reconciled`. No code re-applies inputs after an authoritative state.
-- **F4. Client write scope is a runtime-id string match from options.** `CultNetClientAuthorityScope.Matches` compares `OwnerRuntimeId` with the database's own `_runtimeId` (`CultNetDatabase.cs:111-153`, `EnsureClientAuthority` `:1934`). It gates local prediction only and has no relation to leases.
-- **F5. No authenticated client principal.** `CultMeshSessionIdentity.cs` verifies transports for `(verse, authorityRuntimeId, protocol, routeGeneration)`, which proves the server to the client. The browser client's `runtimeId` (`packages/cultmesh-browser/src/index.ts:182`) and the operation envelope's `SourceRuntimeId` (`CultNetOperationServer.cs:39`) are self-asserted.
-- **F6. No tick scheduler.** A grep of `GameCult.Networking` and `GameCult.Mesh` for tick or timestep names finds none. `Frame` exists only as a witness-asserted number in `CultNetSimulationConsensus` and `CultMeshSimulationFact`.
-- **F7. The game session serves the witness path by default.** `CultMeshGameSession` constructs `CultNetSimulationObservationServer` when `ServeSimulationObservations` (default `true`) and always constructs a `CultMeshSimulationFactCommitter` (`CultMeshGameSession.cs:70-104`). `PredictAsync` is `PutPredictedAsync` (`:161`).
-- **F8. The browser can watch and invoke, not put.** The `cultmesh-browser` README says it "does not expose direct document writes". The client offers `leaseRawDocument` (`index.ts:349`) and `invoke` of typed operations (`:370`), over one WebSocket. On C#: `CultNetDatabaseSubscriptionServer` and `CultNetOperationServer` take `ICultNetSchemaServer`, so they run over `CultNetWebSocketSchemaServer`; `CultNetDatabaseServer` (puts) takes the concrete UDP `Server` (`CultNetDatabaseServer.cs:36`). Operations are request and response with receipts and idempotency keys, which is a poor fit for an input stream at tick rate.
-- **F9. Schema-id namespacing is convention.** `[CultDocument("orbs.player", ...)]` ids are global strings; nothing ties a schema id to a game id.
-- **F10. The in-memory mutation log is never trimmed.** `RecordMutationLogEntry` (`CultNetDatabase.cs:1610`) inserts into a per-shard `SortedList`; no `Remove` or trim on that list exists in the file. Compaction applies to the durable store and to burned sequences only.
-- **F11. CultCache has a write-set batch; CultNetDatabase does not expose one.** `CultCacheBatch` with `Commit` and `TryCommit` (`GameCult.Caching/CultCache.cs:1796`, `:2212`) is the 2.0.0 write set (`variants:ruling:write-set-content-version-declared-ownership`). `CultNetDatabase` has no batch method: every write is a per-record door.
-- **F12. A reflection site on the mesh put path.** `CultMesh.cs:3502` `PutDatabaseDocumentAsync` picks `PutAsync` or `PutPredictedAsync` by `GetMethods` and `MakeGenericMethod`, which matters to the AOT prerequisite (`cultlib-gaps:follow_up:cs-aot-safe-registration`; probe in `research/cultmesh-garden-path/cultcache-aot-probe-2026-10-27.md`).
-
-- **GP1 (runtime probe, 2026-10-28, `imagination-gp-stage1`).** Scratch NUnit test at `51ca81a1`, run on Yggdrasil (`ygg-verify.sh`, `mcr.microsoft.com/dotnet/sdk:10.0`, filter `ImagGpProbeTests`, never pushed to origin). The server writes `gp:player` = "server-owned" through `CultNetDatabase.PutAsync` on a primary shard. `CultNetDatabaseServer._putHandler`, invoked with an uninitialized `CultNetServerPeer` (no field set: no endpoint, no transport, no identity) and a put of "client-overwrote", leaves the record "client-overwrote", and `Server.CanProcessBeforeVerification(put)` returns `true`. Output: `GP1 after=client-overwrote canProcessBeforeVerification=True`, Passed 1. This confirms F1 at runtime: nothing about the peer is consulted, and puts and deletes pass before the legacy login verification (`Server.cs:562-575`).
-- **F13. A server peer carries no identity.** `CultNetServerPeer` (`Server.cs:829`) holds the LiteNetLib `NetPeer`, its endpoint and transport stats. The only principal on `Server` is the legacy username and password login (`PlayerData.PlayerId`, `IsVerified` `:697`), which the database door never reads. `ServerSecurityOptions` is one shared `ConnectionKey`: transport admission, not authority.
-- **F14. A new refusal code is a coordinated change.** The `cultnet.error.v0` `code` is a closed enum (`contracts/cultnet/cultnet.error.schema.json:28-31`, with a byte-identical copy under `packages/cultnet-rs/contracts/`). Rust `CultNetErrorCode` (`packages/cultnet-rs/src/contracts.rs:242-273`) refuses unknown codes, `packages/cultnet-rs/tests/error_message.rs` decodes captured C# bytes per code, and TypeScript imports the root schema (`packages/cultnet-ts/src/contracts.ts:10`). `unowned_schema` was added this way and is the pattern.
-- **F15. Forwarding re-sends as a new client.** `TryForwardPutAsync` (`CultNetDatabaseServer.cs:654`) forwards a `not_primary` put through `ICultNetShardWriteForwarder`, and `CultNetSchemaWriteForwarder` opens its own client connection (`CultNetShardWriteForwarding.cs:122-128`). The primary therefore sees the forwarding runtime, never the original peer.
-- **F16. Consumers of the remote write door.** No C# consumer outside CultLib constructs `CultNetDatabaseServer` (grep of the Aetheria, Epiphany, Ghostlight, huginn and gamecult-ops `*.cs` files finds only vendored CultLib copies). In CultLib, tests reach the put and delete handlers directly in `CultNetJournalTests.cs:738`, `:935-936` and `SoulP4cProbeTests.cs:57`. `CultNetDatabaseServer.ApplyPutAsync` and `ApplyDeleteAsync` (`:73`, `:81`) have no caller in `src` or `tests` besides the handlers. TypeScript puts (the `cultnet-ts` Idunn presence and signed health publishers) target Rust servers.
-- **F17. The Rust document server admits a put by size only.** In `packages/cultmesh-rs/src/rudp_document_server.rs:682-720`, a `DocumentPutRaw` is refused only when its served response would not fit; no authority is asked. This is F1's gap in the Rust runtime (a follow-up, not stage 1).

-## Cut sequence (stage 1)
-
-One line per cut not yet mapped. The model page has no empty cell as of 2026-10-28. Remote write authority (`cultmesh-garden-path:cut_spec:cut-remote-write-authority.r1`, mapped 2026-10-28, so no longer a line here) goes first: it waits on nothing, every later server cut stands on a closed write door, and GP1 shows the door open today. The wasm measuring probe is the sibling that may run beside it, since it touches no file this cut does; ruling `browser-sim-runtime` names it the first cut of the browser runtime track, not of stage 1 as a whole.
-
-- **Wasm runtime measuring probe.** Download size, startup and 60 Hz tick cost of a stub orbs tick under Mono browser-wasm and NetWasm, including `CultCacheBatch` commit cost at tick rate. This is the first cut named by ruling `browser-sim-runtime`, which it can overturn. Its NetWasm and AOT variant waits on `cultlib-gaps:follow_up:cs-aot-safe-registration`.
-- **Witness services off in server mode.** `CultMeshGameSession` stops constructing the observation server and fact committer when the declaration has no checker (F7). Waits on nothing; can run beside remote write authority.
-- **Leases as typed state and the lease-derived grant.** `CultMeshAuthorityLease` becomes a CultCache document, the lease catalog a store view, and the Mesh host's `RemoteWriteAuthority` resolves the connection's principal through `CultMeshAuthorityResolver`. Waits on remote write authority and on session and principal.
-- **Demote `CultNetClientAuthorityScope`.** It becomes derived from the authority declaration (empty in server mode). Waits on game definition.
-- **Changelog entry for the remote write refusal.** `unity/org.gamecult.cultlib/CHANGELOG.md` is also written by `variants:cut_spec:cut-write-ownership-cs.r1`, so Self adds this cut's bullet at merge, after that cut lands, and the two specs share no file.
-- **Game definition and server tick runner.** Builder, document and system registration, definition document and hash, fixed tick, tick-boundary commit. Rests on rulings `tick-model`, `tick-state-commit` and `room-durability`; waits on nothing mapped.
-- **Session and principal.** Join, resume and leave; principal proof; session document. Rests on ruling `player-identity`; waits on game definition (the join checks the definition hash).
-- **Input and snapshot path.** Input messages with redundancy, a server input buffer, acknowledgements, delta snapshots. Rests on ruling `browser-transport`; waits on session and principal.
-- **Browser client runtime.** Wasm simulation host, TypeScript shell for transport and rendering, prediction with replay reconciliation. Waits on the measuring probe and `browser-client-store`.
-- **Orbs reference game and garden-path proof.** The game written with no networking code (`garden-path-needs-no-networking`), and a browser client that writes (`browser-is-first-class`). Waits on all of the above.

-# CultMesh garden path: target
-
-Status: draft target for campaign `cultmesh-garden-path`, 2026-10-27. It holds the
-ends, not the means. The code below is illustrative: it shows what a developer
-should have to write, and no name in it is decided.
-
-## The problem
-
-Operator, 2026-10-27: "the value is in solving the multiplayer scaling problem
-for indie developers in an ergonomic fashion. Having one authoritative server is
-fine, up to a point, but there's no real open source playbook on how to ship an
-MMO, and existing solutions like SpacetimeDB have a huge ergonomics gap. I want
-CultMesh to feel like magic: as a garden path, you annotate your domain POCOs and
-simulation code and declare your authority structure ... and it'll all just work
-without the developer needing to understand networking deeply."
-
-Prior art: `research/cultmesh-garden-path/prior-art-2026-10-27.md` (frameworks,
-ergonomics, scale-out) and `research/witness-authoritative-networking/` (consensus
-and P2P anti-cheat). What the field shows, in short:
-
-- One API over several authority modes ships today (Photon Fusion: Server, Host,
-  Shared; Unity NGO: client-server and distributed authority), and in both the
-  modes leak into the developer's code (`IsServer` against `HasAuthority`,
-  features missing in one mode).
-- SpacetimeDB gives one machine per database. Scaling past it, client
-  prediction, and the reducer-shaped rewrite of game code are left to the
-  developer.
-- Determinism, where it is required at all, is required of the whole simulation
-  (Croquet/Multisynq, Photon Quantum), and that tax is the main ergonomic cost.
-- Shipped world-scale designs treat a spatial unit as indivisible and move
-  players between units (EVE, Pax Dei, Folia); nobody publishes an open,
-  end-to-end playbook (Astron, the nearest, is discontinued).
-
-## What a developer writes (illustrative)
-
-The reference game is a small browser .io game (operator, 2026-10-27: "the .io
-game, Aetheria later"): players steer orbs, eat pellets, and shoot.
-
-```csharp
-[CultDocument("orbs.player", "orbs.player.v1")]
-public sealed class Player
-{
-    [CultIndex] public string Id { get; set; } = "";
-    public Fix2 Position { get; set; }
-    public Fix2 Velocity { get; set; }
-    public int Mass { get; set; }
-}
-
-[CultDocument("orbs.shot", "orbs.shot.v1")]
-public sealed class Shot
-{
-    [CultIndex] public string Id { get; set; } = "";
-    public string Shooter { get; set; } = "";
-    public Fix2 Origin { get; set; }
-    public Fix2 Direction { get; set; }
-}
-
-// Runs every tick. Predicted on the owning client, corrected by authority.
-public sealed class Movement : CultSystem
-{
-    [Predicted]
-    public void Step(Player player, PlayerInput input, Tick tick) { /* ... */ }
-}
-
-// A non-owner may re-run this to settle a dispute, so it must be
-// deterministic. The analyzer enforces that on this system only.
-[Adjudicable]
-public sealed class Hits : CultSystem
-{
-    public HitResult Resolve(Shot shot, Rewind<Player> target) { /* ... */ }
-}
-
-var game = CultMesh.Game("orbs")
-    .Documents<Player, Pellet, Shot>()
-    .Systems<Movement, Eating, Hits>()
-    .Authority(Authority.Server);
-//  .Authority(Authority.TrustedCoop);
-//  .Authority(Authority.Witnessed(w => w.Challenger(Party.Victim).Quorum(3).Arbiter(Party.Server)));
-//  .Authority(Authority.Regions(r => r.Grid(512).Handoff()));   // later: past one server
-```
-
-Changing the authority line is the whole migration between modes, unless the new
-mode re-executes a system on a non-owner and that system is not yet
-deterministic. Then the analyzer names exactly those systems.
-
-## Invariants
-
-- `one-model`: server-authoritative, trusted co-op, witnessed and regioned
-  authority are configurations of one authority declaration, answering per
-  document: who writes, who checks, who arbitrates. No mode has its own API for
-  state, systems or queries.
-- `modes-do-not-leak`: game code does not branch on the authority mode or ask
-  "am I the server"; a system states what it does and the runtime decides where
-  it runs. Where a mode cannot offer a capability, the declaration is refused at
-  startup with a reason, never degraded silently at runtime.
-- `determinism-is-per-system`: only code a non-owner may re-execute must be
-  deterministic. That requirement is marked on the system and checked by an
-  analyzer at build time, not by documentation or by desync in production.
-- `state-is-cultcache`: game state is ordinary CultCache documents; the
-  framework adds no second state model and no JSON on the load-bearing path.
-- `authority-is-typed-state`: who holds authority over what is CultMesh state
-  (leases, shard primaries), inspectable and revocable, never inferred from
-  transport success or peer catalogs.
-- `garden-path-needs-no-networking`: the reference game is written without the
-  developer touching sockets, serialisation, tick scheduling, prediction or
-  reconciliation code.
-- `honest-guarantees`: each mode states its fault model (trusted server, trusted
-  peers, honest-majority sampled witnesses with server arbitration) and its
-  documentation and tests claim nothing past it.
-- `browser-is-first-class`: the reference game's client runs in a browser and can
-  write (submit inputs, own predicted state), not only watch.
-- `built-for-load`: what the garden path ships that is database-shaped (the
-  tick commit, the batch door, logs, subscriptions) is architected for
-  unreasonable load from the start (operator 2026-10-27,
-  `cultlib-gaps:ruling:database-shaped-built-for-load`): "if what we're shipping
-  is database shaped, people will use it as such".
-
-## Sequence (each a campaign or stage of its own; one foundation at a time)
-
-1. Server-authoritative garden path for the .io game: documents, systems,
-   ticked scheduling, client prediction and reconciliation, browser client that
-   writes. This is the proof of ergonomics.
-2. Trusted co-op: authority moves to the owning peer; same game code.
-3. Deterministic dispute kernel (CultMath fixed-point hit tests, cross-runtime
-   vectors) and the `[Adjudicable]` analyzer.
-4. Witnessed authority: signed, hash-chained inputs; victim challenge; sampled
-   network-near witnesses; server arbitration; browser-to-browser channels.
-   Demonstration: a cheating client caught and corrected.
-5. Regions: spatial authority handoff and interest management past one server.
-6. Aetheria on the same declaration.
-
-## Not in scope
-
-- Aetheria until stage 6. Eve and Gjallar (deprecated).
-- A new CultCache storage engine (the paged single-file store stays postponed,
-  `variants:ruling:page-tree-store-postponed`). The garden path fills gaps in
-  their owners, built for load.
-- Asynchronous Byzantine total ordering, zero-knowledge proofs, and chains of
-  any kind.
-- The existing witness aggregator (`CultNetSimulationConsensus`, unsigned and
-  weighted by observed votes) as a base for stage 4: it is the trusted co-op
-  first stage by design and will be replaced, not extended.
-
-## Open forks (to the Fork Desk, each with prior art first)
-
-1. Where simulation code runs in the browser: C# compiled to WebAssembly (one
-   implementation everywhere, which also shrinks the determinism problem to
-   fixed-point maths, at the cost of runtime download size), C# on the server
-   with TypeScript systems in the browser (two implementations of each predicted
-   system), or another arrangement.
-2. Server transport for the browser: WebSocket as today, or WebTransport
-   (QUIC datagrams) on the provider side.
-3. Tick model: fixed tick with a declared rate, or per-system rates.

-verdicts `cut-c2a-element-id-holes.s5` and `.s6`, spec `cut-c2a-ids-header.r1` (`first`). This section keeps
-what was run and what it showed.
-
-**What an id is on disk and in memory.**
-- An id is an ordinary keyed string in the payload. A list element whose `[CultElementId]` member holds
-  `a1b2c3d4e5f6` and one whose plain `Tag` holds the same value encode to identical bytes
-  (`92A1649192AC61316232633364346535663607`; `c2a-ids-header` r1 probe, base `2774a7fe`). No reader can tell
-  from a record's bytes that it holds ids; only the store header says so.
-- `StubArm`, a union arm that is not an object type, is never minted (`imag\imag1.log`, I1): for a document of
-  `StubArm` and `Unit8`, `Plan` counts 1, `StubArm.Id` stays `''`, `Unit8.Id` is minted, `Inspect` reports 0
-  problems.
-- Resolver over-mark (I2): a consumer `[assembly: CultCacheFormatterResolver]` claims a keyed arm with a
-  formatter that writes only `N`. The cache mints an id in memory, `Holds` is true and the header is stamped
-  `v3`, but the payload (`92A263319192009104`) carries no id, and a reopen mints a different one (`8f5e929888ca`
-  in memory, `a1ea2b683d98` after reload). The header claims ids the disk lacks.
-- `[MessagePackFormatter]` on an element type is honoured (I3): the attribute formatter wrote
-  `92A26131919104`, no id, and `Inspect` reported 0 problems at that base. Registration refuses it from r5 on
-  (`declares [MessagePackFormatter]`).
-- Python store (I4): `py-store/leaf-record.cc` (header `v1`, ids `000000000021/22`) loads in C# with
-  `HoldsIds = true`, `IdsInMemoryOnly = false`. A C# write that adds an unrelated record copies it forward,
-  the header stays `v1`, and the ids survive reload. cultcache-py, -ts and -rs have no declaration of which
-  member is an id, so they keep a `v3` they found and never decide one.
-- Header narrowing (`c2a-ids-header` r1): per-record `StoredHoldsIds`, set from the type that decoded a
-  record, is falsified by the identical-bytes probe above. The durable header owns "these stored bytes hold
-  ids" at store granularity. A write that copies any record forward keeps a marked header; only a write that
-  encodes every record decides by content. `StoredHoldsIds` and `KnownIdFree` are deleted.
-- Object list versus value list (r4, `imag-r4\probe1.log`, `probe2.log`): ids sit on object-list elements only
-  (ruling `q7-object-list-elements-only`). `Dictionary`, `ConcurrentDictionary`, `SortedDictionary`,
-  `IReadOnlyDictionary`, and `ILookup` of keyed arms round-trip with the id at
-  the element's own slot (e.g. `ConcDict` `81A16B92AC30313233343536373839616200`: key, then `[id, 0]`). A list
-  or map of scalars has no element to carry one and never enters the id path.
-
-**How MessagePack decides what it writes** (r5 `imag-r5\probe1.log`, `probe3.log`; Soul s5 `job2.log`).
-- Member discovery, `MessagePack.Internal.ObjectSerializationInfo.CreateOrNull(Type, bool forceStringKey,
-  bool contractless, bool allowPrivate)`, is internal, and so is `StandardResolver.Resolvers`. The public
-  surface allows one test: `StandardResolver`'s formatter for `T` is reference-equal to the formatter one
-  public singleton hands out for `T`, each caching one instance per type. `DynamicObjectResolver.Instance`
-  matches keyed classes and structs, `DynamicUnionResolver.Instance` `[Union]` types,
-  `DynamicGenericResolver.Instance` List, arrays, maps, KeyValuePair, tuples, Lazy, Memory, ArraySegment and
-  Nullable, and `ImmutableCollectionResolver.Instance` (namespace `MessagePack.ImmutableCollection`)
-  `ImmutableArray` and `ImmutableList`. Asking `DynamicObjectResolver` for a collection type throws
-  `TypeInitializationException`, so a family probe swallows exceptions.
-- Kind facts (`probe3`): a `[MessagePackObject]` class implementing only `IEnumerable<T>` or
-  `IReadOnlyList<T>` (`KBag`, `KNode`, `KRo`) is written by key (object resolver). One that is also
-  `ICollection<T>`, a `List<T>` subclass or a `Dictionary` subclass (`KC2`, `KColl`, `KList2<T>`, `KDict`) is
-  written as a collection (generic resolver) and its `[Key]` members are dropped.
-- Member facts (`probe3`; `ap` is `AllowPrivate`, `R` written, `W` read back). A member is written when it
-  has an integer `[Key]`, no `[IgnoreMember]`, and is a public field or a property with a public getter. It is
-  read back when it is a public non-readonly field, a property with a public setter (`init` counts), or a
-  `[SerializationConstructor]` parameter. At `ap=False`: `PG` (private getter) `R=False W=True`, `PS`
-  (private setter) `R=True W=False`, `GetOnly` `R=True W=False`, `InitOnly` both. `IdPriv`
-  (`Id { get; private set; }`) is written and not read back (wire `91AC62...`, back `<null>`), and `IdCtor` is
-  `W=False`. At `ap=True` every one of these, `priv` included, is `R=True W=True`, except `GetOnly`
-  (`W=False`).
-- AllowPrivate attribute form (Soul s5 `SoulS5Probe.C`, `ApTrueArm`): on a type declared
-  `[MessagePackObject(AllowPrivate = true)]`, `StandardResolver` writes private `[Key]` members and a
-  private-setter id round-trips. The oracle test calls `CreateOrNull(type, false, false, false)` and reports
-  none of them, so the walk's member set misses that form.
-- Collection written as object (r6 `probe2.log`): a `[DataContract]` class implementing only `IEnumerable<T>`
-  over an id-carrying arm (`DcSeq`) is a collection in the walk, yet `StandardResolver`'s formatter is
-  `DynamicObjectResolver`'s (wire `91 91 91 92 AC..`, written as an object). A `[DataContract]` `List<T>`
-  subclass (`DcColl`) is written by the generic resolver, and the object resolver hands out a different
-  instance for it. For `DcBad` (two members on one `Order`) `StandardResolver` uses the generic resolver, and
-  Soul s5 measured both `DcColl` and `DcBad` passing the door.
-- Geometry (r6 `probe2.log`, `probe3.log`): Geometry has a direct MessagePack 3.1.7 `PackageReference`, so the
-  source generator runs, and its assembly carries `[GeneratedAssemblyMessagePackResolverAttribute(
-  typeof(GeneratedMessagePackResolver), 3, 1)]`. For `CultGeometryDomainNode`, `DomainDocument` and
-  `FeatureClaim`, `StandardResolver` returns `GeneratedMessagePackResolver`'s formatter and every public
-  singleton returns a different instance or null. For `CultGeometryDomainNode[]` and `FeatureClaim[]` it is
-  the generated resolver's `ArrayFormatter`, not `DynamicGenericResolver`'s. No Geometry id-path type matches
-  a family singleton. Caching.Tests has no generator (analyzers do not flow through a `ProjectReference`), so
-  its keyed types match `DynamicObjectResolver`.
-- Generated assemblies (Soul s5, fresh generator-enabled assembly `SoulGen`, `job2.log` GEN rows): a keyed
-  `List` or `Dictionary` subclass (`GKColl`, `GKDict`) is written by key, wire `["c",[7]]`, with its elements
-  dropped by MessagePack; the walk reads it by key too (Plan 0). A generated-assembly `[DataContract]`
-  enumerable (`GDcSeq`) is still written by `DynamicObjectResolver`, because the generator emits no
-  DataContract formatters.
-- Null standard (Soul s6 finding `null-standard-untyped`): for a non-generic interface or abstract class that
-  enumerates arms, `StandardResolver` returns null instead of throwing, and the door neither refuses nor
-  types it.
-- Wire pin (Soul s5, s6 `SoulS5Pin`): a deterministic document with 12 minted ids, encoded by the codec and
-  decoded independently with `MessagePackSerializer.ConvertToJson`, carries every id. The ids are
-  byte-identical at `494ad9ab` and `57fdf70c`, `0f8964b58a08` and `7eb4fb13d530` among them.
-- Not measured: Unity/IL2CPP, where the package bundles its own `MessagePack.dll` (version not read) and the
-  dynamic resolvers cannot emit, and MessagePack versions other than 3.1.7.

-Imagination scratchpad `imagination-c2a-closed-world-r2`).
-- Shapes the walk does not own already behave as whole values. A keyed document holding
-  `ImmutableArray<PElem>`, `(List<PElem>, int)`, `KeyValuePair<string, List<PElem>>`, a non-enumerable
-  `[DataContract]` holder, or a string-keyed holder (`[Key("items")]`) gives `Inspect` problems 0, an empty
-  IdPath, `CanHoldIds` false, `Plan` 0 (random and deterministic), and `Holds` false with ids set.
-- The marker and the copy check do not count them. Committed with ids `aaaaaaaaaaaa`/`bbbbbbbbbbbb`, the store
-  header stays `cultcache.store.v1`. A fresh cache that writes another record over that file (the copy-forward
-  check) keeps `v1`. Reload returns the ids exactly as written, and unset ids stay null after write and reload.
-- Variants replace them whole, and that is the C2a resolver's behaviour for every list. A variant `Set` of the
-  `ImmutableArray` slot resolved to `[9:eeeeeeeeeeee]` with the base untouched, header `v2`, `HoldsIds` false.
-  A path step `[1:aaaaaaaaaaaa]` is refused: "this runtime resolves top-level Set overrides only". No C2a gap.
-  The gap belongs to C2b, in the cut sequence below.
-- AllowPrivate is read from the most derived `[MessagePackObject]`. `ApDerived` (AllowPrivate over a base
-  without it) is written `[[],[],4,[]]`: base-chain privates and a private-getter property, with
-  `ObjectSerializationInfo` at `allowPrivate: true` = `[baseStash, own, N, Pg]`. `NoApDerived` (plain over an
-  AllowPrivate base) is written `[nil, 5]`. The walk read only `[N]` for both.
-- A `[DataContract]` `List<T>` subclass is written by `NonGenericListFormatter`, and its record does not read
-  back ("System.Object[] is not of type PElem"), whatever the walk does. That is a MessagePack limit, not an
-  id fact.

A refusal names a header only as `cultcache.store.v<digits>`.
 - **Derived state.** The write header is never decided by the writer: it is the reader's verdict (header read, whole-store flag, whether ids or variants are held). A rewrite of a file that cannot be read cannot happen, because the reader throws first.
 - **Forbidden writers.** A second header classifier. Deleted: Rust `leading_header`, `read_array_header`, `read_string`; cultnet-ts's own decode of the store header; the TS async `readStore`; Rust `StoreUnreadableError` (negative grep `StoreUnreadableError` in `packages/cultcache-rs`: no match); Python `_decode_v1_snapshot`.
-- **Shared paths.** cultnet-ts reaches the header decision only through `readSingleFileStore` (AUTH:4, :321) and checks only record count, schema id and type. cultnet-ts therefore needs a cultcache-ts release that exports it, which is the release that ships with this change; the manifests move to that version then (c0-ships-with-c2a), not before.
+- **Shared paths.** cultnet-ts reaches the header decision only through `readSingleFileStore` (AUTH:4, :321) and checks only record count, schema id and type. cultnet-ts therefore declares cultcache-ts `^0.15.0`, the first release that exports it.

-# Element-id sweep list (C2a)
-
-Data for the per-consumer sweep in docs/document-variants-cut.md, C2. Every object type below sits in a list (`List<T>`, `T[]`, `IEnumerable<T>`, and the like) reachable from a registered document type, and needs one string member with `[Key(n)]` and `[CultElementId]` before that consumer can take a CultLib that requires ids. A union base takes the member on the base; its subclasses inherit it, so put the slot above the subclasses' highest key.
-
-Method: a static scan of `F:\Projects\<consumer>` C# files for types marked `[CultDocument(`, walked through keyed members, base classes, dictionary values and `[Union]` subtypes. Read-only; no consumer was edited. Worktree copies (`Aetheria-catalog`, `CultLib-*`, and so on) are excluded. Struct elements are values and need no id. Non-C# consumers carry the id as an ordinary member and are not listed. The scan is text-based: a document registered without a literal `[CultDocument(` attribute, or a type whose members lack an integer `[Key]`, is missed, so the sweep pass should confirm each repo by registering its types once.
-
-Lines: `Type  file:line  (via Owner.Member)`, paths relative to the consumer root.

-C2a adds ids to: `CultGeometryDomainNode`, `CultGeometryFeatureClaim`, `CultGeometryContributionRow` (`src/GameCult.Geometry/CultGeometryDocuments.cs`); `CultMeshBodyDescriptor` (`src/GameCult.Mesh/CultMeshBodies.cs:35`); `CultMeshDiscoveryCandidateDocument` (`CultMeshDiscoveryService.cs:418`); `CultMeshEntityPrefabAssetRef`, `CultMeshEntityPrefabComponent`, `CultMeshEntityPrefabNode` (`CultMeshEntityPrefabs.cs`); `CultWitnessContractPin`, `CultWitnessArtifactEntry`, `CultWitnessTimingEntry` (`src/GameCult.Networking/CultWitnessArtifactBundle.cs`).
-
-`CultMeshCdnChunkRef` (`src/GameCult.Mesh/CultMeshCdn.cs:73`) has a derived id, `[CultElementId(nameof(Offset))]`: the decimal text of its offset, never random, so packing the same body encodes the same manifest bytes. `contracts/cultmesh/content-vectors.*.json` and the Rust runtime carry it. A consumer with content-addressed elements declares the same way.

-## 1. Established practice: who pays for a breaking upstream change, and when
-
-- **Abseil / live at head (S1, S2).** Recommends users track the latest code. Says it will provide a tool to perform an API refactor for well-behaved code (S1). Requires of downstream: show how you call it, stay within the compatibility guidelines; otherwise fork or use periodic supported branches (about every 6 months, patched 2 years) (S1). Says every change is potentially breaking for someone; breaks are announced in commit messages and LTS notes, and users are asked to report undetected breaks on GitHub (S2). Users should be able to temporarily pin to an earlier commit if a newer change is a problem (S2). S1/S2 do not mention Rosie, the Beyonce rule, or caller-fixing; the fetched pages describe tooling and a feedback channel only.
-- **Live at Head as described in SWE at Google ch. 21 (S3).** Providers are expected to test changes against downstream dependents before committing; breaking changes wait until dependents are updated or an automated migration tool exists. Consumers must keep meaningful tests. Stated preconditions: unit tests across dependencies run in CI, a visible reverse-dependency graph, substantial compute, no pinning of dependencies, provider acceptance of the downstream-testing duty. Called "costly but effective" inside Google and "largely unproven at scale." Notes that under SemVer a major bump costs maintainers little and many indirect users a lot. Ch. 16 (S4) does not address live at head; it states large-scale changes across trunk are costly and tooling-supported.
-- **Go MVS (S5).** Selects the oldest version satisfying all declared minimums. Publishing a new version changes nobody's build; a consumer gets it only when a requirement names it, directly or through another module. Upgrades are explicit edits to `go.mod` by the top-level module. Compatibility rule: newer versions inside one major version are expected to work where older did; a major version is a different module identity. Cost of a breaking change falls on whoever opts into the new version, at the time they opt in.
-- **Cargo (S6).** Git dependency without `rev` takes the default-branch tip at first build and fixes that commit in `Cargo.lock`; changes arrive only on `cargo update`. A `rev` in `Cargo.toml` pins explicitly; the Cargo book calls hand-managed SHAs "tedious and error prone" and prefers the lockfile. Consumer pays at `cargo update` time.
-- **npm (S7).** `package-lock.json` records the exact tree; installs stay on it until the lockfile changes and is committed. It is not published with a package. The page gives no timeline for when updates reach a consumer.
-- **Chromium DEPS (S8).** `DEPS` stores dependency URLs and commit hashes (often in `vars`). Developers roll with `gclient setdep`, `roll-dep`, or manual `git update-index`; some projects (Skia) are autorolled. The page says manual rolling after an upstream change is good practice to confirm the roll compiles and tests pass. It does not describe revert procedure. Cost is paid by the roller at roll time.
-- **Git submodules (S9).** The superproject records one commit SHA (gitlink, mode 160000). Upstream commits never move the pin; it moves when someone updates the checkout and commits the new SHA in the superproject. Collaborators receive the pin via pull and must run `git submodule update`.
-
-## 2. Internal precedent
-
-- **Aetheria pin (L1).** `Directory.Build.props` holds `CultLibRevision` (currently `45c2f4006f5f7dab357426cabd3197e8d0a17f66`) and `CultMathRevision` (`9c1b06cd703bfa44352050e819b0d0659cf5978a`). `Directory.Build.targets` target `VerifyCultLibRevision` (BeforeTargets `ResolveProjectReferences`) errors if the sibling checkout's `git rev-parse HEAD` differs from the pin, or if `git status --porcelain` is non-empty; escape hatch `SkipCultLibRevisionCheck=true`. File is 39 lines; the pin is one pair of properties per pinned package.
-- **Why added (L1 git).** Commit `4f4beb0f` (2026-09-14, "Pin CultLib for headless builds"): "Directory.Build.targets carries Delvehold's VerifyCultLibRevision guard, checking for CultMath.csproj: HEAD must equal the pin and the worktree must be clean." Commit `e91ba369` (2026-09-24, "Pin CultLib per package, as Unity's manifest does"): headless build must compile the revisions Unity consumes; a single pin would have compiled six commits of newer CultCache under headless tests while Unity stays on its tag. The Aetheria cut doc (L2, ~line 1905) calls the guard "the only working pin for a sibling checkout." Aetheria's `Packages/manifest.json` pins Unity packages by git tag.
-- **Pin guard already in Delvehold (L4/search_sources hit, `Delvehold:Directory.Build.targets`)** and a variant in AetheriaEve (archived, `Aetheria.State.Dependencies.targets`, also checks a Unity package tree hash). Delvehold's guard checks `GameCult.Mesh.csproj` exists, HEAD equals `CultLibRevision`, tree clean. Date of Delvehold's first guard: not determined.
-- **Consumer table (L2, Q6 in Aetheria `docs/cultcache-migration-cut.md`).** Aquarium, Ymir, AquaSynth, Mimir, Gjallar: ".NET sibling, unpinned", compile against main at once. Brokkr, Eve, EveUnity, EvePlugins: "Unity package / sibling", pin "various". Delvehold: sibling with revision guard at `334e60f`, 52 behind, "Not until it re-pins." Heimdall: submodule `b6b1d9c`. Rust consumers (Idunn, Epiphany, Odin, Ghostlight, Muninn, Ratatoskr, CodexConnector): Cargo by commit.
-- **Operator discussion (L4).** voidbot `search_history` ("pin CultLib revision vs track main for consumers"; "Brokkr Eve sibling CultLib checkout build pin") returned no relevant operator statement on pinning versus tracking; hits were unrelated Discord chatter. Nearest operator words found in the Discord index: Metacrat, 2026-05-09, "Oh, anyone using CultLib will still be paying the blood price, you can count on that" (message 1502671320406687894; context not fetched, so its subject is not confirmed). No operator quote on pinning versus tracking was found in memory files grepped (`C:\Users\Meta\.claude\projects\F--Projects\memory`, pattern pin/track main/unpinned/sibling) beyond a retired Idunn pin line and Odin/Muninn pin-branch coordination notes.
-- Aetheria cut doc operator mentions near pins are about content (Schematic-shape drawer, 2026-09-14; Studio grouping, 2026-09-17), not pinning policy.
-
-## 3. Current state of the two consumers (L3)
-
-- **Eve.** `packages/org.gamecult.eve.surface/GameCult.Eve.Surface.csproj:16` `CultLibRoot` defaults to `$(MSBuildThisFileDirectory)..\..\..\CultLib`; lines 20-21 ProjectReference `$(CultLibRoot)\src\GameCult.Caching\...` and `...\GameCult.Mesh\...`. `tests/GameCult.Eve.Surface.Serialization.Tests/*.csproj:19` references `$(CultLibRoot)\src\GameCult.Mesh\...` (and Eve.Surface by relative path). `git ls-files` shows only `packages/org.gamecult.eve.surface/Directory.Build.props` (sets only BaseOutputPath/BaseIntermediateOutputPath/MSBuildProjectExtensionsPath, no revision). No `Directory.Build.targets`, no `global.json`, no `.gitmodules`, no revision property or check. Eve also holds Cargo.toml/Cargo.lock (Rust side, not examined).
-- **Brokkr.** `brokkr-command/Brokkr.Command.csproj:7`, `brokkr-contracts.Tests/Brokkr.Contracts.Tests.csproj:7`, `brokkr-contracts/Brokkr.Contracts.csproj:8`: `CultLibRoot` defaults to `..\..\CultLib`. ProjectReferences: Caching, Caching.MessagePack, Mesh, Networking (by project). No `Directory.Build.*`, no `.gitmodules` in `git ls-files`; no revision property or check.
-- Neither repo contains `CultLibRevision`, a `VerifyCultLibRevision` target, or any HEAD check. Both build whatever `F:\Projects\CultLib` currently holds (including dirty or other-branch states).
-- Fork text claims (not re-verified here): Eve.Surface has 0 `[CultElementId]`; Brokkr `[CultDocument]` files show no object lists by grep.

-# Prior art: read with an old writer schema, then write back
-
-Facts only. Pages were fetched 2026-10-23 through a summarising fetcher; "not stated" means the fetched page did not say it, not that no source does. Items marked (memory) are my background knowledge, not verified from a fetched page.
-
-## 1. Apache Avro
-- Source: https://avro.apache.org/docs/current/specification/ (Schema Resolution; summarised via apache/avro doc source), Java `DataFileWriter` javadoc (1.11.1).
-- Model: the writer schema travels with the data. The reader resolves it against its own reader schema. Resolution is a read-time projection; the spec defines no write-back.
-- Data loss on projection: "the writer's value for that field is ignored" when the reader schema lacks the field. A reader-only field takes its default, or the read errors if it has none.
-- Write-back: the spec states no rule. Object container files store one schema in the header ("Each datum in a file is of the same schema"). `appendTo` is documented only as "Open a writer appending to an existing file"; it does not say which schema the append uses. (memory: Java `appendTo` reuses the file's header schema, so an append never restamps.)
-- Stated reason for the read-time design: readers and writers evolve separately (fields added or removed in a different software version).
-
-## 2. Protocol Buffers (proto3)
-- Source: https://protobuf.dev/programming-guides/proto3/ (Unknown Fields).
-- On write: unknown fields are "included during parsing and in the serialized output" (matches proto2). Round-trip keeps fields the current type does not know.
-- Loss cases the page lists: serializing to JSON, and copying a message field by field into a new message (it recommends `CopyFrom`/`MergeFrom`).
-- No schema id or version is written. The wire format carries only field numbers, so "restamp" has no meaning here.
-- Not stated: behaviour in versions before 3.5 (memory: proto3 dropped unknown fields before 3.5, then reversed). The Java reference page says nothing on preservation.
-- Stated reason: preserve data across a mixed-version fleet.
-
-## 3. Confluent Schema Registry
-- Source: https://docs.confluent.io/platform/current/schema-registry/fundamentals/schema-evolution.html
-- BACKWARD (default): consumers on the new schema read data written with the new or the previous version. FORWARD: data written with the new schema is readable by consumers on the old one. FULL: both.
-- Write: "Each schema version gets a unique ID and an incremented version number." A producer writes under the schema it holds (its own current version). The id is stamped per message at serialisation, from the producer's schema.
-- Upgrade order is how the rules prevent loss. BACKWARD means upgrade consumers before producers. FORWARD means upgrade producers first, and keep old-schema data away from consumers until they are upgraded.
-- Not stated on the page: what a consume-modify-produce app writes. (memory: it re-serialises under its own latest schema, so fields it does not model are lost unless a compatibility rule kept them.)
-- The registry gates registration. It does not gate individual rewrites.
-
-## 4. Document DBs and ORMs with stored versions
-### MongoDB schema-versioning pattern
-- Sources: https://www.mongodb.com/blog/post/building-with-patterns-the-schema-versioning-pattern ; https://www.mongodb.com/docs/manual/data-modeling/design-patterns/data-versioning/schema-versioning/
-- Documents carry `schema_version` (absent means 1). The app keeps a handler per version and writes new documents at the current version.
-- Migration strategy is the app's choice: migrate all, migrate "when accessed" (lazy), or never.
-- Not stated: whether an update of an old document restamps it. The manual's update example branches on `schemaVersion` and writes into each version's own shape. It notes its `else: null` branch adds stray null fields to the other shape.
-- Stated reasons: no downtime, failed migrations easier to handle, timing flexibility. Cost: handler code per live version.
-
-### Realm (Atlas Device SDKs, now deprecated)
-- Source: https://www.mongodb.com/docs/atlas/device-sdks/sdk/swift/model-data/change-an-object-model.md
-- Per-file schema version. A changed schema needs an incremented `schemaVersion`, plus a `migrationBlock` for non-trivial changes. The file is migrated whole at open, before any read or write, and Realm "will throw an error" if the version is lower or the same but the schema differs.
-- No lazy per-object restamp. Writes happen only on a migrated file.
-- Data loss: the manual says "Deleting a property will not impact existing objects", i.e. removal is automatic and needs no developer step. Required new properties and renames need a manual block. (memory: removed-property values are dropped from the file.)
-
-### Core Data
-- Source: web search results only (Apple forum threads 745114 and 785427, WWDC22-10120, "staged migrations" doc). The Apple docs URL I tried returned 404.
-- A store whose model hash differs from the current model fails to open with an incompatible-version error. Opening migrates the whole store when `NSMigratePersistentStoresAutomaticallyOption` and `NSInferMappingModelAutomaticallyOption` are set. Lightweight migration covers only obvious patterns (add entity, remove relationship, required to optional, rename). Anything else needs a staged or custom migration.
-- Migration is store-wide at open. It does not happen per record on write.
-
-### EF Core
-- Not fetched. (memory: no per-row schema stamp. Migrations are explicit, ordered DDL, tracked in a `__EFMigrationsHistory` table.)
-
-## 5. Old-schema data held read-only until explicit migration
-### Elasticsearch archive indices
-- Sources: https://www.elastic.co/docs/deploy-manage/upgrade/deployment-or-cluster/reading-indices-from-older-elasticsearch-versions ; https://www.elastic.co/guide/en/elasticsearch/reference/current/archive-indices.html ; 8.0 migration notes (7.0+ indices readable, 6.x or earlier must be reindexed).
-- Indices from an older major are readable through search and field-caps. "They do not support the Get API or any write APIs."
-- The route to a writable copy is reindex into a new index that is "fully compatible with the current Elasticsearch version". `_source` is readable, so no data is lost on reindex.
-- Stated reason: the page does not say why they are read-only. It describes archive access as "slower read-only access", with limited query capability. Some legacy mappings cannot be imported (the original is kept in `_meta`), and that is the one place the page shows a lossy translation.
-- Third-party (Search Guard blog, unverified against Elastic): in 9.x a plain `index.blocks.write` does not satisfy the boot check; `index.verified_read_only` is needed.
-- This is the closest match to option (b) in the fetched set: an old format, readable but not writable, left until the owner reindexes it.
-
-## Where restamp-on-write loses data (from the sources above)
-- Avro: a field present in the writer schema and absent from the reader schema is dropped at read, "ignored". Any rewrite from the resolved value would omit it.
-- Protobuf: unknown fields survive a binary round trip. They are lost via JSON, or when copied field by field.
-- Realm: removed properties are deleted by the automatic migration.
-- MongoDB: a handler that writes only the current shape can lose or relocate old-shape fields (the manual's example adds nulls).
-- Confluent: loss is prevented by compatibility rules at registration time, not at each write.
-
-## Pattern across the set
-- No fetched system restamps a single record on write when the record's writer schema differs from the application's type, on an app-visible, per-record basis.
-  - Avro, protobuf and Confluent carry the schema per file or message.
-  - Realm, Core Data and Elasticsearch move or block the whole store or index at open.
-  - MongoDB leaves it to the app.
-- Whole-store migration at open is the usual explicit step (Realm, Core Data). Elasticsearch is the one case of read-only-until-reindex.
-- Not found: a system that declares per-schema-id compatibility, as in option (b). Avro schema resolution and Confluent compatibility rules are the nearest analogues. Both are read-side or registration-side declarations.

-
-## 1. Goetz et al., Java Concurrency in Practice (Addison-Wesley, 2006), ch. 10 "Avoiding Liveness Hazards"
-Status: EXISTS, SECTION NUMBER CORRECTED.
-- "Open Calls" is **10.1.4**, not 10.1.3. 10.1.3 is "Deadlocks Between Cooperating Objects"; 10.1.2 is "Dynamic Lock Order Deadlocks"; 10.1.5 is "Resource Deadlocks". Source: text extracted from a PDF copy of the book (its TOC lists Listing 10.6 "Using Open Calls to Avoiding Deadlock Between Cooperating Objects", p. 133). The copy is an unofficial one at library.megu.edu.ua; a publisher link was not checked.
-- (a) 10.1.3 gives the warning sign: an "alien method" (defined p. 40 as a method whose behavior the calling class does not fully specify) called while holding a lock. Paraphrase: such a call may take other locks (deadlock risk) or block a long time, stalling threads that need the lock you hold. 10.1.4 defines an open call as a call made with no locks held (credited to Lea, CPJ 2.4.1.3) and says programs restricted to open calls are far easier to analyze for deadlock-freedom than ones that allow alien calls under lock.
-- Cost it names: moving a call out of a synchronized block makes an atomic operation non-atomic (its getImage example stops being a snapshot). Where atomicity is needed it suggests structuring so only one thread can run the code path after the open call (service shutdown example).
-- (b), (c): not addressed in this section.

-## 2. Sutter, "Effective Concurrency: Avoid Calling Unknown Code While Inside a Critical Section"
-Status: VERIFIED, with date caveat.
-- Dr. Dobb's column in the "Effective Concurrency" series. Sutter's blog teaser is dated 2007-11-06: https://herbsutter.com/2007/11/06/effective-concurrency-avoid-calling-unknown-code-while-inside-a-critical-section/ . Original link ddj.com/architect/202802983; Dr. Dobb's mirror https://drdobbs.com/cpp/avoid-calling-unknown-code-while-inside/202802983 (4 pages). The Dr. Dobb's issue date was not shown in anything fetched; the blog date is the only date confirmed. www.drdobbs.com did not resolve from this machine, so the column body comes from search-result summaries and the blog teaser, not a full first-hand read.
-- (a) Core claim: locks do not compose; two separately correct modules can deadlock when combined. Trigger: caller inside a critical section, callee enters another critical section or blocks, another thread can take the same two in the opposite order. "Unknown code" listed as: library functions, plug-ins, callbacks/function pointers, virtual methods, generic types.
-- Mitigations listed: move the call outside the critical section; pass copies instead of shared data; narrow the critical section (finer locks, reader-writer); require callees not to block (documentation/discipline only).
-- (b), (c): not addressed.
-
-## 3. Linux lockdep
-Status: VERIFIED, with a nuance.
-- Source: kernel docs "Runtime locking correctness validator", https://docs.kernel.org/locking/lockdep-design.html .
-- (b) Lockdep tracks lock classes, not instances, and records dependencies between classes as sequences are observed. It reports a circular order as a potential deadlock even if the deadlock never happened. Its "Proof of 100% correctness" section says that once each simple single-task locking sequence has occurred at least once, no timing of them can deadlock. Each new lock chain is validated once and hashed; repeats skip validation.
-- Nuance: it flags the dependency edge that closes a cycle, so both orders must have been exercised at some point (possibly by different, non-concurrent runs). A lone nesting is flagged only if it breaks a single-lock rule (IRQ-safe vs unsafe, same-class recursion). "Refuses on first sight" fits the closing edge or a single-lock rule violation only. It warns; it does not block the acquisition.
-
-## 4. ConcurrentHashMap re-check after locking
-Status: VERIFIED.
-- Source: OpenJDK java/util/concurrent/ConcurrentHashMap.java, `putVal` and `computeIfAbsent`: head node `f` is read unlocked, `synchronized (f)` is taken, then `tabAt(tab, i) == f` is re-checked; on failure nothing is done and the loop retries. The overview comment gives the reason: the locked node can be replaced, so first-in-bin must be confirmed after locking. (Only the first 100k of 269k chars were read; both methods were reported found there.) Empty-bin `computeIfAbsent` uses a ReservationNode plus CAS instead.
-- (c) This is the pattern: choose the lock from an unlocked read, validate the read after acquiring.
-
-## 5. LMDB
-Status: VERIFIED (paraphrase). Not about alien code or lock order.
-- Source: lmdb.h, `mdb_txn_begin` and `mdb_env_open` (https://github.com/LMDB/lmdb, libraries/liblmdb/lmdb.h). A thread may hold one transaction at a time (plus children); a transaction and its cursors belong to one thread; one write transaction at a time, so writers cannot deadlock each other; MDB_NOTLS ties reader slots to the txn object instead of the thread, and the application must then serialize writers itself because write locking is unaware of user threads.
-- Relevance: "one hold per thread" as a deliberate rule, parallel to CultCache's one-cache-gate-per-thread.
-
-## 6. SQLite btmutex.c
-Status: VERIFIED (summary of trunk source).
-- Source: https://github.com/sqlite/sqlite/blob/master/src/btmutex.c (read via raw.githubusercontent.com; sqlite.org served a bot check).
-- (b) Prevention by ordering, not detection: sharable B-trees on a connection sit in a list sorted by BtShared address and are always locked ascending (`sqlite3BtreeEnterAll`). `sqlite3BtreeEnter` try-locks first; on failure it releases later-ordered locks, waits, then reacquires in order. `wantToLock` is a count that makes a non-recursive mutex behave recursively.
-- No alien-code or callback discussion in these comments.
-
-## Counter-positions and how they stay safe
-- Callbacks under lock, documented: Java `ConcurrentHashMap.compute`/`computeIfAbsent`. Javadoc (Java 21): the function should be short and simple because other threads' updates may block meanwhile, and must not modify the map. The javadoc does not say "internal lock"; that it runs under the bin lock is inferred from the source in item 4. Safety rests on documented restrictions, not enforcement.
-- Opposite choice: .NET `ConcurrentDictionary.GetOrAdd(key, valueFactory)`. Writes use fine-grained locks but valueFactory runs outside them, "to avoid the problems that can arise from executing unknown code under a lock" (doc remarks). Price: not atomic; the factory may run more than once; a recheck decides the winner (another thread's insert wins). https://learn.microsoft.com/en-us/dotnet/api/system.collections.concurrent.concurrentdictionary-2.getoradd . Same shape as option `encode-first` (user code outside the lock, then recheck and commit) and as item 4.
-- JCIP and Sutter both name the cost of leaving the lock: lost atomicity. Sutter also offers "pass copies" and "callee must not block" as alternatives to leaving.
-- Not researched (no source fetched): Linux notifier chains, Java `synchronized` event listeners, other systems that call back under lock by design. No verified citation for them.

-## A. Local mechanics (CultLib, read-only, `C:\cl-wt\c2a-land\src\GameCult.Caching\CultCache.cs`)
-
-- `CultDocumentRegistry.Shared` is `Lazy<CultDocumentRegistry>` (line 639-645). Its public constructor calls `Refresh()` (647-650), which scans `ReflectionExtensions.GetAttributedDocumentTypes()` (688; defined in `ReflectionExtensions.cs:10`) and rebuilds the indexes under `_registrationGate`. So Shared's initial content is whatever `[CultDocument]` types are in loaded assemblies at first touch of `Shared`.
-- `GetRequired(Type)` (697-711) registers an unregistered `[CultDocument]` type on demand. So Shared also grows whenever any caller asks for a type. `Refresh()` is public and rebuilds the index from currently loaded assemblies.
-- `ForTypes(IEnumerable<Type>)` (658-669) builds a registry with `discoverLoadedDocuments:false`, containing only the given types (plus those `GetRequired` pulls in).
-- `CultCache(registry = null, ...)` sets `_registry = registry ?? CultDocumentRegistry.Shared` (2202-2205).
-- `WriteDocument<TDocument>(key, doc, storedAt, registry = null)` (4515-4545): `resolvedRegistry = registry ?? Shared`; `catalogEntry = resolvedRegistry.GetRequired<TDocument>().ToCatalogEntry()`; then `Cacheless(resolvedRegistry, ...)` lends that registry to the store for the call. XML doc (4510) says Shared "can only refuse more".
-- `WriteRecord(..., registry = null)` (4491-4497): XML doc (4489) says that with registry omitted "it decides nothing for copied records and the one entry is the only claimant".
-- `OwnsOnDisk(upserts)` (4741-4759): when the store is cacheless and upserts are given, ownership of an on-disk record is decided by `CultDocumentRegistry.Owns(id, catalog, declared, new CatalogEntryLookup(writes, AttachedRegistry), ..., claimant => writes.Any(entry => entry.SchemaId == claimant.SchemaId))`. The comment (4731-4735, 4738-4740) says written entries shadow the lent registry's type for their ids, the registry adds other claimants, and the record is owned only when the claimant is a written entry, "a registry can only refuse more". `CatalogEntryLookup` ctor at 604 takes `(entries, CultDocumentRegistry? others)`.
-- Net: with `registry == null` the lent registry's claimant set is Shared's current contents, which depend on assemblies loaded and on every prior `GetRequired` call in the process.

-## B. Q1. Process-global, lazily filled registries in established libraries
-
-### MongoDB C# driver, `BsonClassMap`
-- Global: yes. `BsonClassMap.RegisterClassMap` is process-wide static; unregistered types are auto-mapped on first use. Docs: "You must register a class map _before_ it's needed in your code." and "We recommend registering class maps before initializing a connection with MongoDB." https://www.mongodb.com/docs/drivers/csharp/current/serialization/class-mapping/ (WebFetch; the page itself says nothing on freezing or late-registration errors).
-- Behaviour depends on what has been touched: EF Core provider issue EF-88 reports "Unknown discriminator value 'List`1'" when the first operation after startup is a read; reporter links it to a class map that is created only on write. Status Closed/Fixed in 8.0.0; page has no maintainer comment. https://jira.mongodb.org/browse/EF-88 (WebFetch). Reporter says explicit `RegisterClassMap` at startup did not fix it for them.
-- A MongoDB community answer (via search summary, not opened): discriminator mappings persist once registered, so a read after an insert works; fix offered is `[BsonKnownTypes]`. https://mongodb.com/community/forums/t/c-driver-why-is-bsonknowntypes-attribute-needed-for-polymorphism/2183 (summary only).
-- Register-once contract: CSHARP-4424 states the three `RegisterClassMap` methods are "meant to only be called once for a given type"; requested because several libraries share data models and do not control init order. Closed Done, fix version 2.19.0; the page does not say which API shipped. https://jira.mongodb.org/browse/CSHARP-4424 (WebFetch). Community workaround named in search summary: `BsonClassMap.IsClassMapRegistered`.
-- CSHARP-1879 (search summary): `RegisterClassMap` accepted an unfrozen map and failed later on use; fixed 2.4.2. https://jira.mongodb.com/browse/CSHARP-1879 (not opened).
-- CSHARP-5597 (search summary): `BsonSerializer.RegisterDiscriminator` has no effect; discriminator dictionary populated at class-map registration. https://jira.mongodb.org/browse/CSHARP-5597 (not opened).
-- Polymorphic docs: "You must specify hierarchical discriminators in root-to-leaf order." and the relationship of all classes in a hierarchy must be documented before deserialization. https://www.mongodb.com/docs/drivers/csharp/current/serialization/polymorphic-objects/ (WebFetch).
-- Particular docs report an order-dependent GuidSerializer failure ("incorrect order of class mappings"). https://docs.particular.net/persistence/upgrades/mongodb-4to5 (search summary, not opened).
-- Did they move away: not found. Class maps remain global static; mitigation is documentation plus the IfNotRegistered API.
-
-### protobuf-net `RuntimeTypeModel.Default`

-- Global mutable default exists: `MessagePackSerializer.DefaultOptions`. README (WebFetch): labelled "Global state; Not recommended when writing library code." Safe if you control all MessagePack code; libraries should pass options explicitly because others "may change this static property." Libraries "must not use StaticCompositeResolver - as it is global state". https://github.com/MessagePack-CSharp/MessagePack-CSharp/blob/master/README.md
-- Resolvers are an ordered list (`CompositeResolver`): order matters by construction.
-- Whether it moved away from the global: not found.
-
-### System.Text.Json
-- `JsonSerializerOptions.Default`: "Gets a read-only, singleton instance"; remarks give a performance reason: shared instance avoids "redundant recomputation of converters". https://learn.microsoft.com/dotnet/api/system.text.json.jsonserializeroptions.default (WebFetch). The page states no rationale about cross-component interference; any such reading is inference. Design-discussion issue in dotnet/runtime: searched, not found. Whether Default was ever mutable: not verified.
-- Type-info resolvers: not researched beyond the above.
-
-### Json.NET
-- `TypeNameHandling` is a security concern, not an order concern: CA2326 says "An attacker could modify the serialized data to include unexpected types"; mitigation is a custom `ISerializationBinder` restricting types. https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/quality-rules/ca2326 (WebFetch).
-- `JsonConvert.DefaultSettings` global behaviour/guidance: the Newtonsoft page fetched says nothing about global effects. Not verified.
-
-### Orleans
-- Serializer discovery is build-time source generation (`[GenerateSerializer]`, `[Id]`), not a runtime scan; the docs' older code-generation section lists scan of assemblies referencing the core library plus `KnownType`/`KnownAssembly` attributes. Aliases: "Type aliases are globally scoped, and you cannot have two aliases with the same value in an application." https://learn.microsoft.com/en-us/dotnet/orleans/host/configuration-guide/serialization (saved locally: `C:\Users\Meta\.claude\projects\F--Projects-CultLib\0840c7c7-0e31-410e-9012-afb79c3c0742\tool-results\toolu_0148m7no1AbrJzWmNLicn6N9.txt`, lines 134, 839-841).
-- Type manifest / codec registry runtime behaviour, issues: not researched.
-
-### EF Core
-- Model is built per `DbContext` type and cached (IMemoryCache; "the built model has a cache size of 100"); initialised at first operation: "just creating a DbContext instance does not cause the EF model to be initialized." https://learn.microsoft.com/en-us/ef/core/performance/advanced-performance-topics
-- Assembly scan: `ApplyConfigurationsFromAssembly` — "The order in which the configurations will be applied is undefined, therefore this method should only be used when the order doesn't matter." https://learn.microsoft.com/en-us/ef/core/modeling/ ; and "`EntityTypeConfigurationAttribute` types will not be automatically discovered in an assembly."
-- So EF's registry is per context type, not process-global; assembly scan is opt-in and documented as order-undefined.
-
-### Marten
-- Storage is a table and upsert function per document type, alias `mt_doc_<alias>`; alias collisions are resolved with `DocumentAlias`. https://martendb.io/schema/storage (WebFetch). Hierarchies share one table via `AddSubClass<T>()`; subclass docs are "stored as the parent type" in the identity map. https://www.martendb.io/documents/hierarchies (WebFetch). Schema is configured in `StoreOptions` per store, not a process-global.
-
-### Java ServiceLoader
-- "Service providers are loaded and instantiated lazily, that is, on demand." Providers on the class path load in the order `getResources` finds config files; "The ordering of modules in a module layer is not defined." "Instances of this class are not safe for use by multiple concurrent threads." Caches cleared by `reload`. https://docs.oracle.com/en/java/javase/21/docs/api/java.base/java/util/ServiceLoader.html (WebFetch). Visibility is class-loader dependent ("must be visible to the class loader").
-
-## C. Q2. Write/overwrite decisions against an existing record of another type
-
-- RavenDB: REST put docs, request body section: updates must "include its collection name in the metadata" and "A document's collection cannot be modified." Server error code for mismatch: the first fetch summary said HTTP 500; not confirmed on a second fetch. https://docs.ravendb.net/7.1/client-api/rest-api/document-commands/put-documents (WebFetch twice). Ayende, RavenDB 4.0 storage: document key namespace is global, same key cannot exist in two collections (summary). https://ayende.com/blog/173954/the-design-of-ravendb-4-0-physically-segregating-collections The check is against the collection named in the write (derived from the writer's type by the client), not a registry; the "client maps entity type to collection" part is inference from the search summary, not a quoted source. `PutDocumentCommand` page: a missing collection means `@empty`; concurrency via `changeVector`, null "to skip the check". https://docs.ravendb.net/client-api/commands/documents/put
-- Marten: per-type tables, so the same id under two types are two rows in two tables; no cross-type check. Same id across subclasses of one hierarchy table: not covered by docs fetched; unverified. Marten docs: upsert is used so users "don't have to check whether a document is new or existing" (search summary of https://www.martendb.io/documents/storing, not opened).
-- MongoDB: the server has no type; `_id` unique per collection; the C# driver writes a `_t` discriminator from the written object's class map. Whether the driver checks an existing document's `_t` on replace: not researched; nothing found stating it does.
-- Couchbase: key unique within a collection; upsert replaces; no server-side type field enforcement; guidance is one type per collection. https://docs.couchbase.com/server/7.0/learn/data/scopes-and-collections.html (search summary, not opened).
-- Orleans: grain identity is type plus key ("type/key"), so same key under two grain classes is two identities, not a conflict. https://learn.microsoft.com/en-ca/%20dotnet/orleans/grains/grain-identity (search summary, not opened). How storage providers key state: not found.
-- Result of this pass: no store found in which a process-global type registry decides whether a write may replace an existing record of another type. Found: collection/type fixed by metadata of the writer (RavenDB), type as part of the key (Orleans, Marten tables), or no check (Couchbase upsert). This is a negative search result, not proof of absence. Not searched: Cosmos DB, DynamoDB, EF Core TPH update of an existing row with another discriminator, Realm, LiteDB, Akka.Persistence.
-
-## D. Q3. Guidance on ambient/global registries and determinism
-
-- Mark Seemann (ploeh, 2019): after discussion with co-author van Deursen, "Ambient Context really is an anti-pattern." Reasons given: he has never used it and superior alternatives exist; he says the claim is unproven. https://blog.ploeh.dk/2019/01/21/some-thoughts-on-anti-patterns/ (WebFetch). Examples he cites as found in the BCL (search summary, not verified on page): `Thread.CurrentPrincipal`, `CultureInfo.CurrentCulture`, `HttpContext.Current`. DI book 2nd ed. chapter 5 lists it among DI anti-patterns: https://www.oreilly.com/library/view/dependency-injection-principles/9781617294730/OEBPS/Text/c05.xhtml (not opened).
-- MessagePack README (above) is itself a library-author statement on global mutable defaults. MongoDB CSHARP-4424 (above) states the shared-library init-order problem. EF Core docs (above) state assembly-scan order is undefined.
-- No .NET guidance specifically about AppDomain-wide/assembly-scan registries and write decisions found.
-
-## E. Not verified / gaps
-- protobuf-net lazy registration, freezing and bug history.
-- Why System.Text.Json made Default immutable; no maintainer statement found.
-- Json.NET DefaultSettings guidance.
-- RavenDB exact error text and HTTP status; whether the stored document is unchanged after refusal.
-- Marten same-id-across-subclasses behaviour.
-- MongoDB driver behaviour on replacing a document whose `_t` differs.

-- `F:\Projects\CultLib\src\GameCult.Caching\CultCache.cs:717-718` schemaId = Sha256(BuildSemanticFingerprint(...)). `:735-761` fingerprint = `schemaName|schemaVersion` then per member ordered by Slot: `slot:MemberName:TypeName:ref|value:TargetSchemaName:one|many`. `contentHash` (`:716`) is a separate Sha256 of canonical JSON (`:763+`).
-- `TypeName` = `CultSchemaTypeNames.FromType`: CLR `Type.FullName` (namespace-qualified), generics as `Name<args>`, arrays `T[]` (`src\GameCult.Caching\CultSchemaTypeNames.cs:9-31`). So the fingerprint contains .NET type names as well as member names.
-- Contract `Contracts\cultcache-persistence-format.md:257-284` lists what canonicalization must preserve: slots, types, required/default, nullability, collection semantics, enum constraints, encoding shape. Member names and declared schema name are not in that list. `:171-179` says the id is not derived from C#/Rust/TS type names and the same shape should give the same id "regardless of origin language". `:180-190` defines schemaId = "same semantic persistence shape?" vs contentHash = "exact same canonical schema document?". Example catalog entry (`:140-170`) carries optional `supersedesSchemaIds`, `migrationFamily`; its example canonicalSchema fields do carry `"name": "Name"` (PascalCase). Soft-migration reader flow `:286-345` (exact_match / soft_migrate / reject).
-- Runtimes do not derive ids; they emulate C# names:
-  - Python: `packages\cultcache-py\src\cultcache_py\documents.py:326` `member_name=_pascal_case(field.name)`; `:516-517` splits on `_` and capitalises. `schema_id` defaults to `self.type` (`:218`); `compatible_schema_ids` field (`:188,242`).
-  - TypeScript: `packages\cultcache-ts\src\codec.ts:226-232` `pascalCase` (splits on non-alphanumerics), `:267` `memberName: pascalCase(field.name)`; throws if a codec has no C# type name (`:~262`).
-  - Rust: `packages\cultcache-rs\src\lib.rs:295,308` `serde(rename_all = "camelCase")` on envelope structs; `schema_id: Some(T::TYPE.to_string())` at `:2856`. I did not trace how Rust document types obtain a sha256 id.
-  - Python test pins a literal id from shared vectors: `packages\cultcache-py\tests\test_cultcache.py:808` (`tests\vectors\document-variants-c0`).
-- C# also has `CompatibleSchemaIds` (`CultCache.cs:28,313,570`): a record whose persisted id is in the list is accepted (an alias-list mechanism; I saw only the grep lines, not the logic).
-- Ruling `variants:ruling:wire-id-is-version` (eureka-state, InForce, ruled 2026-09-30, operator quote "Agreed on schema identity"): wire schema id = declared version string `<name>.vN`; every runtime stamps/resolves it exactly; a wire binding without `.v<digits>` is refused; "Store ids are unchanged." Cited source: document-variants-cut.md:552-555 (not opened).
-
-## 1. How established formats define identity/compatibility, and whether names participate
-
-Protocol Buffers (fetched https://protobuf.dev/programming-guides/proto3/ and /json/)
-- Field number identifies the field in the binary wire; changing it = delete + add. Field names appear only in TextProto/JSON encodings; reserve deleted numbers and, for JSON/text, names. The proto3 page has no explicit safe/unsafe entry for renaming; names matter only for JSON/text.
-- JSON mapping: names become lowerCamelCase unless `json_name` is set; "Parsers accept both the lowerCamelCase name" and the original proto name (/programming-guides/json/).
-- Message type identity in `Any` is by name: default type URL `type.googleapis.com/<package>.<message>`, "a globally unique identifier" (proto3 page, #any). Type identity is nominal; compatibility is by field numbers.
-
-Apache Avro (fetched https://avro.apache.org/docs/1.11.1/specification/)
-- Parsing Canonical Form (PCF): STRIP keeps only attributes relevant to parsing (type, name, fields, symbols, items, values, size); doc and aliases dropped; FULLNAMES replaces short names with fullnames and drops namespace attributes. Textually equal PCF means "the same" for any reader. Names ARE in the canonical form (record and field names), as is field declaration order. Defaults are absent from the kept list (extractor's inference; spec text not confirmed).
-- Fingerprints: CRC-64-AVRO in single-object encoding (marker C3 01 + 8-byte LE fingerprint); spec recommends at least a 64-bit Rabin, with SHA-256 / MD5 options for larger sets.
-- Name rules: `[A-Za-z_][A-Za-z0-9_]*`, dot-separated namespaces, equality on case-sensitive fullname.
-- Resolution: records match on same unqualified name; "Named types and fields may have aliases"; implementations "may optionally" use aliases to map writer to reader. So in Avro names participate in identity (fingerprint) and resolution; aliases are the rename mechanism and are excluded from the fingerprint.
-
-Cap'n Proto (fetched https://capnproto.org/language.html)
-- Files and types carry 64-bit IDs; `capnp id` generates them randomly. Default ID for a declaration without one = first 8 bytes of MD5 of (parent scope ID, declaration name). "You cannot change the name of a type that doesn't have an explicit ID"; symbolic names can change if ID/ordinals stay. Stated rationale for IDs: short, unambiguous, full names waste wire space. The page does not say why structural hashes were rejected; I found no Varda statement (search pointed at a mailing-list thread "Schema Refactoring and Unique IDs", Aug 2023, unopened).
-- Encoding page (https://capnproto.org/encoding.html, fetched): adding fields is backward compatible because field positions depend only on lower-numbered fields; nothing on type identity.
-
-FlatBuffers (fetched https://flatbuffers.dev/evolution/ and /schema/)
-- Field positions by declaration order or explicit `id: n` (contiguous from 0, on all fields if used). Renaming "generally OK" because names are not in the binary. `file_identifier` is exactly 4 chars at bytes 4-7; docs frame it as a file-level check and recommend unions for distinguishing messages.
-
-Thrift (fetched https://raw.githubusercontent.com/apache/thrift/master/doc/specs/thrift-binary-protocol.md)
-- Binary protocol: field header = type + field id; "the field name is not encoded". (IDL page gave nothing on omitted ids.)
-
-MessagePack-CSharp (fetched https://github.com/MessagePack-CSharp/MessagePack-CSharp, first 100k of 105k chars)
-- `[Key(int)]` on all members => array encoding; string keys => map. Keys should be sequential from 0 (gaps cost nulls); do not reuse indexes of removed members; keep obsolete members until clients update. Union keys are ints, unique, serialized as [key, object]. No type identity in the payload.
-
-Microsoft Bond (fetched https://microsoft.github.io/bond/manual/bond_cpp.html)
-- Changing field ordinals breaks wire compat; no explicit versioning; Simple JSON matches by field name so a rename breaks it. No schema hash/GUID documented there. Bebop: wiki page empty (points to docs.bebop.sh, not opened).
-
-Unison (fetched https://www.unison-lang.org/docs/the-big-idea/ and /docs/language-reference/unique-types; hash size from search summary)
-- Definitions identified by hash of syntax tree; names are "separately stored metadata"; hash excludes names (512-bit SHA3 per search summary, unopened).
-- Structural types: "Unison does not uniquely identify a type by its name"; same-shape types are the same type (Suit/Direction, four nullary constructors, interchangeable). `unique` types: compiler generates a UUID that feeds the hash, so identity becomes nominal. Which is the default keyword was not confirmed.
-
-IPLD (fetched https://ipld.io/docs/schemas/)
-- Matching is structural: "the names of types aren't expected to be found in the serialized data"; match is by structural outline. The page does not say schemas are themselves content-addressed. Versioning is left to developers; "Migrations" subpage not opened.
-
-## 2. Failure modes of purely structural identity
-
-- Unison documents it directly: structurally identical enums are one type unless declared `unique` (unison-lang.org/docs/language-reference/unique-types, fetched). Its mitigation is a per-declaration UUID mixed into the hash (identity re-nominalised).
-- Language literature (summary, pages not opened): structural typing is prone to accidental conformance/type equivalence; nominal typing prevents it at the cost of rigidity (Wikipedia "Nominal type system"; arXiv 1007.2123 lecture notes; Erlang nominals doc https://www.erlang.org/doc/system/nominals.html says nominal types exist to prevent misuse of same-structure types). TypeScript "brand" = phantom discriminator field. No serialization-specific source found.
-- Formats that avoid the collision by carrying a name or tag outside the shape: protobuf Any type URL (full name), Avro fullname in PCF, Cap'n Proto explicit IDs, Unison `unique`, MessagePack-CSharp union key ints, FlatBuffers file_identifier/unions.
-- Not found: a documented incident of two same-shape serialized types colliding under a structural id (one search, nothing).
-
-## 3. Failure modes of name-inclusive identity across languages
-
-- Protobuf: default camelCase conversion is "always valid but not necessarily unique"; proto3 compiler rejects JSON-name conflicts; serialized duplicate keys parse differently by runtime (Edition Zero design doc, summary: https://flutter.googlesource.com/third_party/protobuf/+/HEAD/docs/design/editions/edition-zero-json-handling.md). Snake_case vs camelCase JSON mismatches in practice: https://github.com/fullstorydev/grpcurl/issues/105 (summary); https://github.com/open-telemetry/opentelemetry-proto/issues/476 (summary: spec contradicted itself on camelCase vs original names). Protobuf's mitigation: parsers accept both forms.
-- Serde (fetched https://serde.rs/container-attrs.html): `rename_all` accepts lowercase, UPPERCASE, PascalCase, camelCase, snake_case; per-field `rename`.
-- Avro restricts names to `[A-Za-z_][A-Za-z0-9_]*` with case-sensitive fullname equality, so snake_case and PascalCase spellings are distinct names; renames go through aliases, which PCF drops.
-- Cap'n Proto: auto-derived IDs depend on the declaration name, so a rename without an explicit ID changes the ID.
-- Bond Simple JSON: rename breaks compatibility (name matching).
-- Local: Python/TS already convert to PascalCase to reproduce C#'s fingerprint (section 0); the fingerprint's TypeName is the CLR full name (`CultSchemaTypeNames.cs:30`) and TS throws when a codec lacks a C# type name.
-- Registry normalisation (summary): Confluent Schema Registry `normalize.schemas=true` maps semantically-equal schemas to one id (https://www.confluent.io/blog/best-practices-for-confluent-schema-registry/); sources disagree on whether JSON Schema property order is normalised.
-
-## 4. Migration precedents for changing identity derivation
-
-- Git SHA-1 -> SHA-256 (fetched https://git-scm.com/docs/hash-function-transition): per-repo format marker (`extensions.objectFormat`, `compatObjectFormat`, `repositoryFormatVersion=1` makes old git refuse); bidirectional SHA-256<->SHA-1 mapping (pack idx v3, `loose-object-idx`); four transition modes (dark launch, early, late, post); conversion at the network boundary. It is a design doc, not a statement of what has shipped.
-- IPFS CIDv0 -> CIDv1 (fetched https://docs.ipfs.tech/concepts/content-addressing/): v0 (46 chars, "Qm") and v1 (self-describing version/codec/multihash) coexist; `ipfs cid format -v 1` converts; v1->v0 only for dag-pb.
-- Docker manifest schema 1 -> 2 (summary, mirror pages unopened): digests differ per manifest format; pull-by-digest gets no translation, pull-by-tag may be translated; repush converts. https://pulp.plan.io/issues/2099.
-- Warpcast API hash v1 -> v2 (summary, https://warpcast.notion.site/Warpcast-API-Hash-Migration-Public-ccdd6de8ac604783b9596cfd623ddbac): two-week dual-hash period, then only v2.
-- Cap'n Proto explicit-ID escape hatch for renamed/moved declarations; Avro aliases as the rename bridge in resolution; MessagePack-CSharp keep-obsolete-members (all fetched, above).
-- Local: contract `supersedesSchemaIds` / `migrationFamily` (`cultcache-persistence-format.md:~140-170`) and C#/Py `CompatibleSchemaIds` exist as alias lists.
-- Not found: Unison changing its hash derivation (one search, no docs); any serialization store that switched from name-inclusive to structural ids.

-## Could not verify / not done
-- Cap'n Proto designer's rationale against structural hashing (not in docs; mailing list unopened).

-CultLib is one stack in several languages: **CultCache** (typed `.cc` persistence),
-**CultNet** (schema-v0 wire messages and transports) on top of it, and **CultMesh** (Verse
-discovery, replication, authority) on top of that. **CultMath** and **Geometry** sit beside the
-stack as portable numerics and engine-neutral geometry. The C# runtime in `src/` is the
-reference; the other runtimes keep wire parity with it.

-If you want typed state on disk, start with CultCache. Everything else assumes it.

-# Recipe: a two-client .io game over CultCache + CultMesh (TypeScript)
-
-A tiny arena. One process is the authority: it holds a single `io.arena_state` document in a CultCache
-and serves it over CultMesh. Each client discovers the authority through the Odin catalog, leases the
-document, and invokes `join`, `move` and `leave` operations. Two clients see each other join, move and
-leave because both lease the same document.

-| Browser bundle builds and the page is served | **tested** (HTTP fetch only) |

-| Run by CI / `npm run test:ts` | **not yet**: the recipe has its own `package.json` (for `ws`) outside the workspaces; run it by hand as below |
-| Authority state on disk (`.cc` file) | **not yet**: the arena cache is in memory |
-| Remote play: Odin roots and a signed route | **not yet**: the client uses `local-development` trust, loopback only |
-| Dropped players: a closed tab that never sent `leave` stays in the arena | **not yet**: operations do not carry a connection identity to the authority |
-| `CultCache` in the browser | **not yet**: the `@gamecult/cultcache-ts` entry imports Node built-ins, so the client keeps the decoded document in a variable and only `./document` is imported |
-
-No `@gamecult/cultmesh-ts` or `@gamecult/cultnet-ts` TypeScript authority server exists. The server below is the CultNet
-message handling a provider owes, written in this recipe with the `ws` package.
-
-## Run it
-
-```
-npm ci --ignore-scripts                          # repo root
-(cd packages/cultnet-ts && npm run build)        # then cultcache-ts, cultmesh-browser, same command
-cd docs/start/io-game && npm install
-npm test                                         # node --test arena.test.ts, Node 24
-node serve.ts                                    # http://127.0.0.1:8080, open it twice
-```
-
-Tested on Node v24.14, which runs `.ts` files directly (no type check; `tsc` is not part of this recipe).

-# Write-ownership map
-
-Imagination, 2026-10-27/28, session `self-2026-10-27c-eureka`. Base: CultLib `main` at `b7a68884` (C2a landed).
-Serves `variants:follow_up:write-ownership-cut`. Spec: `variants:cut_spec:cut-write-ownership-cs.r1`. Question:
-`variants:question:written-type-undeclared-drift`.
-
-## The rulings: what decides and what illustrates
-
-- `variants:ruling:cache-refuses-retype`. Her words decide: a stored record's schema id identifies its type, so a write of
-  another type at that key is the wrong type and is refused, by a cache exactly as by a cacheless write. Retyping is an
-  explicit remove plus add. The Household / `_pet` / rake analogy is an illustration, not a rule about object fields. Self's
-  gloss (ownership becomes per staged key) is Self's reading, not hers.
-- `variants:ruling:write-ownership-by-written-type`. Her words decide one thing: a record under the written type's own id is
-  equivalent by construction, so which type owns that id cannot change the write. The full rule ("own id or one the written
-  type declares it migrates from; anything else is refused; no registry, Shared included, and no owner/lister precedence
-  enters a write's ownership decision") is Self's reading, which she accepted in the same exchange. Her remark that ids
-  indicating structural equivalence beats demanding names match is context for the open
-  `variants:question:store-schema-id-derivation`, not a ruling here.
-- In force and touched: `variants:ruling:drift-record-write-ownership` (operator: a type that reads a record as compatible
-  drift owns it and restamps it, as 2.0.1 does), `variants:ruling:mesh-writes-bound-by-declaration`,
-  `variants:ruling:undeclared-read-only`, `variants:ruling:unheld-removal-refused-at-commit`,
-  `variants:ruling:unheld-removal-multi-store-cost-ruled`.
-
-The two Self readings disagree on one case: a record under an undeclared older id of the written schema name, read whole
-(an undeclared version bump). Literal "anything else is refused" makes it read-only; `drift-record-write-ownership` makes it
-owned. That is `variants:question:written-type-undeclared-drift`, and only the operator can settle it.
-
-## Body facts (probed at b7a68884)
-
-Probes: scratch tests in this worktree, removed. C# filtered runs on Starfire (one job each); TS and Rust on Yggdrasil
-(`ygg-verify.sh`, scratch commit `78f604fd`, not pushed to the forge); Python locally. Types A (`tests.wo_a`) and B
-(`tests.wo_b`) share one shape; N1/N2 are two versions of `tests.wo_n`, nothing declared.
-
-| Probe | C# | TypeScript | Rust | Python |
-|---|---|---|---|---|
-| P1 cache {A,B}: B at k, then A at k | **C**: B's record replaced, k now A's id | C, and **both** records live at k | C, both live at k | C, both live at k |
-| P2 cache {A} only, store holds B at k, write A at k | R `CultSchemaConflictException` (B is foreign, carried) | R at load: "No schema is registered for persisted schema id" | R at load, same | R at load: "Unknown persisted document type" |
-| P3 cacheless `WriteDocument<A>` over B, registry null / {A} / {A,B} | R / R / R | no cacheless write | no cacheless write | no cacheless write |
-| P4 cache {A,B}: remove k and upsert A at k in one batch | C (k is A's) | n/a | n/a | n/a |
-| P5 cache {A,B}: remove, then add in a second commit | C | n/a | n/a | n/a |
-| P6 N2 over an N1 record (undeclared name drift), cache {N2} / cacheless reg {N2} | C restamped / C restamped | not probed | not probed | C (cache) |
-
-What this establishes:
-
-- C#: one record per key. The only path that retypes is the cache arm (P1): `CacheBackingStore.RefuseUndeclared`
-  (`CultCache.cs:3994-4009`) and the on-disk judge (`OwnsOnDisk`, `:4731-4763`) ask `Registry.Owns(schemaId, catalog)`
-  (`:841-842`), which answers per schema id for the whole registry: any registered type declaring the id makes every
-  registered type's write to that key owned. The cacheless arm already refuses the retype (P3) but decides it through
-  `CatalogEntryLookup`'s registry half (`:596-634`) and the claimant precedence, which is what the ruling removes.
-  The judge is also per batch, not per key: the cacheless predicate's `declared` is the union over every written entry
-  (`:4752-4754`), and `UndeclaredOnDisk` memoises one answer per schema id (`:4784-4797`).
-- Retype as remove plus add already works in the cache (P4, P5); the cut adds no new primitive.
-- Directory store: its own judge (`DirectoryMessagePackBackingStore.cs:287-306`) asks `Registry.Owns` for every key,
-  upserts included. It must take the same per-key rule.
-- TypeScript, Rust, Python: records are keyed by `(type, key)` (Rust `entries: BTreeMap<(String, String), _>`,
-  `lib.rs:2659`; TS `#entryId(definition.type, key)`, `cult-cache.ts:323`; Python sorts and stores by `(type, key)`).
-  A write of A at k never meets B's record: both live at k (P1). None carries a foreign record; a store holding an
-  unregistered type does not load (P2). So no leaf has a "write meets another type's record" path to fix. Bringing the
-  ruling to the leaves first needs C#'s key identity (one record per key) and C#'s foreign carry, which are parity changes
-  of the leaves' store model, not a write-ownership rule. Owned by the new follow-up `variants:follow_up:leaf-key-identity-parity`.
-- Interop (unproven): a Python store holding A and B at k fails C# decode first on payload encoding (Python's
-  lambda-defined document wrote JSON payloads), so what C# does with two records at one key was not reached.
-
-## Model and authority table
-
-| Value | Today (b7a68884) | After the cut |
-|---|---|---|
-| May an upsert of T replace the stored record at k? | cache: `Registry.Owns(id)` (any registered type); cacheless: union of written entries' declarations plus claimant over written entries and the lent registry | **Owner: `CultDocumentRegistry.WrittenOwns(T's entry, stored id, catalog)`**, per key, both arms, both store kinds |
-| May a removal (or check) at k proceed? | cache: `Registry.Owns`; cacheless: the written-entries predicate | unchanged in kind: cache `Registry.Owns`; cacheless: owned when some entry the call writes `WrittenOwns` it (no registry) |
-| Which type reads a record (claimant precedence) | `Claimant<T>` | unchanged; read machinery only, no write asks it except through `WrittenOwns`' one-entry lookup (option `own-entry-reads-whole`) |
-| Lent registry in a cacheless write | encodes, decides copied-record v3 header, adds claimants | encodes and decides the copied-record header (`CopiedHoldIds`, `:4600-4630`); **adds no claimants** |
-| `CatalogEntryLookup` registry half (`_others`, `Other`, `Others`) | live | **deleted** |
-| `CultDocumentRegistry.Lookup` | live | **deleted** |
-| `Owns<T>`'s `mayClaim` | live | **deleted** (the lookup holds only the written entry) |
-| Foreign record at k | refused for every write | unchanged |
-
-Authority map (also in the spec):
-
-- Owner: `WrittenOwns(written, storedId, catalog)` decides whether an upsert of `written` may replace the record stored at
-  its key. Inputs: the written catalog entry, the stored record's schema id, the catalog that publishes it. Nothing else.
-- Derived: `Registry.Owns` is demoted to the removal/check rule and to load-time read-only marking; it no longer decides
-  upserts. `Claimant` is read machinery.
-- Forbidden writers: `Registry.Owns` on an upsert key; `CatalogEntryLookup` with a registry; the per-batch union `declared`;
-  the per-schema-id memo across different written entries.
-- Shared paths: cache staging (`Claim` -> `RefuseUndeclared`, `:3156`), single-file on-disk judge (`ApplyWriteSet` ->
-  `RefuseUndeclaredOnDisk`, `:4565`, `:4736`), single-file `JudgeChecks` (`:4726`, checks only), directory store judge,
-  `WriteRecord`, `WriteDocument`, unattached `PushAll`, Mesh's `WriteSingleFileDocument` and raw-payload write.
-
-## Absorb or leave
-
-- `variants:follow_up:drift-write-ownership-leaves`: **leave**, but it now waits on `leaf-key-identity-parity`. Its premise
-  (give each leaf the C# Owns rule) assumes one record per key, which no leaf has (P1). The leaf write-ownership cuts in the
-  sequence below close it together with this follow-up's leaf half.
-- `variants:follow_up:public-store-writes-behind-cache`: **leave**. It asks who may stage behind an attached cache (API
-  shape); this cut changes what any staging is judged by. No collision: direct `Push`/`CommitBatch` reach the same on-disk
-  judge, so they get the per-key rule for free. Hands must not give direct staging a different predicate.
-- `variants:follow_up:writer-dangling-link-tolerance`: **leave**. Rust/TS whole-store `push_all` reading a dangling link is
-  a reader/writer tolerance question, not ownership; this cut touches no leaf.
-
-## Deferred doc findings this cut fixes
-
-The ownership-docs rewrite in part 1 is the fix for (each resolved `Deferred` to `write-ownership-cut`):
-`variants:finding:cut-claimant-one-owner.s2.changelog-underdescribes-refusals`,
-`variants:finding:cut-claimant-one-owner.s3.changelog-misstates-subset`,
-`variants:finding:cut-claimant-one-owner.s5.refusal-list-ignores-declared-win`,
-`variants:finding:cut-claimant-one-owner.s5.shared-read-stated-as-contract`.
-Sites: `unity/org.gamecult.cultlib/CHANGELOG.md:16`, `src/GameCult.Caching/Contracts/cultcache-persistence-format.md:209-219`,
-`CultCache.cs` `WriteRecord`/`WriteDocument` registry docs (`:4476-4519`). Self closes them `Fixed` after Soul holds.
-
-## Cut sequence
-
-1. `cut-write-ownership-cs` (spec r1, admitted, blocked on `variants:question:written-type-undeclared-drift`): C# reference,
-   both arms, both store kinds, docs. Lands before the 3.0.0 release cut.
-2. `leaf-key-identity` (one per leaf, TS, Rust, Python; follow-up `leaf-key-identity-parity`): one record per key and
-   foreign carry at C# parity, with a cross-runtime vector. Not mapped.
-3. `leaf-write-ownership` (one per leaf, after 2): `WrittenOwns` per leaf; closes `drift-write-ownership-leaves`. Not mapped.
-
-Leaves ship on their own versions (cultcache-ts 0.14.2), not in the 3.0.0 Unity package, so 2 and 3 do not gate 3.0.0;
-whether they must land first is Self's call.

-# Changelog
-
-## Unreleased
-
-### Changed
-
-- `msgpack` is a hard dependency, as `pyproject.toml` declared it. The optional-import fallbacks and the `cultcache-py[msgpack]` extra they named (which never existed) are gone: a missing msgpack is an `ImportError` at import.
-- The single-file store's `push`, `push_all` and `delete` take the cross-process lock on `<path>.lock` (flock; LockFileEx over the whole file on Windows) across the read and the replace, waiting up to `lock_timeout` seconds (30 by default, `TimeoutError` after), and exclude the C#, Rust and TypeScript runtimes' writers. The staged file is `<path>.tmp-<pid>-<uuid>`, fsynced before the replace, with a directory fsync after it off Windows. A fixed `<path>.tmp` is no longer used.
-
-### Breaking
-
-- A single-file store written as `cultcache.store.v3` is read and written: a record that holds an element id (an owned list element with an `[CultElementId]` member, carried through every write) marks the store v3, and a v3 store is carried through a rewrite with its ids. A runtime from before this change refuses a v3 store by name.
-- A write over a file the reader refuses (`StoreUnreadableError`, from `push`, `push_all` and `delete`) refuses and leaves the file as it is. A flush used to replace such a file. A write set cannot merge with a disk it cannot read, so the file is repaired or removed by its owner before the store writes again.
-- Added `StoreUnreadableError` (a `ValueError`) for a store file this runtime cannot read, and `SchemaConflictError` (a `ValueError`) for a
-  write the catalog cannot describe. A store is exactly three slots; a schema is never recovered from a record's payload.
-- The single-file writer derives the catalog from the records it writes: one entry per carried schema id, the registered entry over an
-  arrived one, written as chosen and never merged. A cache stamps a record with its registered schema's id.
-- Every registration refusal is now a `SchemaConflictError`, a `ValueError`, where it was a `CultCacheError`, a `RuntimeError`: registering a document type or a schema name twice no longer raises what `except CultCacheError` or `except RuntimeError` catches.
-- Two documents that own one schema id are refused at registration (`SchemaConflictError`). 2.0.1 accepted them. A document may still list another's id as compatible.
-- A loaded record resolves by its schema id first: the document that owns the id, else the one document that lists it as compatible; several listers and no owner refuse the record with `SchemaConflictError`. The record's type name resolves it only when its schema id names no registered document. 2.0.1 resolved by the record's type name alone.

-# Changelog
-
-All notable changes to `cultcache-rs` are recorded here, following
-[Keep a Changelog](https://keepachangelog.com/en/1.1.0/). Earlier releases are recorded
-only in git history.
-
-## Unreleased
-
-### Breaking
-
-- A single-file store written as `cultcache.store.v3` is read and written: a record that holds an element id (an owned list element with an `[CultElementId]` member, carried through every write) marks the store v3, and a v3 store is carried through a rewrite with its ids. A runtime from before this change refuses a v3 store by name.
-- A write over a file the reader refuses (a zero-byte file, a truncated store, a stamp this runtime does not read) refuses with `CultCacheStoreUnreadable` and leaves the file as it is. A whole-store write used to replace such a file. This reverses 0.3.1, where `push_all` replaced a file with no readable stamp (healing it); the stamp rule now has one owner, the reader every write asks under the lock, and it accepts v1 and v3 (0.3.1 refused v3).
-
-### Added
-
-- Lookups, matching the C# `GetByName`, `GetByIndex` and `GetGlobal`. `#[cultcache(name)]` and `#[cultcache(index)]` / `#[cultcache(index = "alias")]` on `DatabaseEntry` fields and `#[cultcache(global)]` on the struct give `CultCache::get_by_name`, `get_by_index` and `get_global`. An empty name and a blank index value are not found; records of one type sharing a name or value find the one with the smallest key. A second record of a global type under another key is refused on every write path and on load with `CultCacheSecondGlobal`. Two `name` members, or two members with one index alias, are refused at compile time. A member's text comes from `CultLookupValue` (`String`, `Option` of one, integers, `bool`, `char`).
-- `SchemaConflictError`, the typed refusal of a write the catalog cannot describe: records of different types under one schema id, or an arrived schema and a registered one that share an id and disagree on the schema name. A whole-store write (`push_all`) refuses with it, names the schema id, the names involved and a record key, writes nothing and leaves the file as it is. A caller tells it apart with `error.downcast_ref::<SchemaConflictError>()`.
-
-## [0.3.1]
-
-### Fixed
-- `push_all` reads the store's header under the lock and refuses a format this runtime does
-  not read, with `CultCacheStoreUnreadable` `UnsupportedFormat`, leaving the file as it was.
-  A file with no readable stamp is still replaced, so a whole write heals it.

 All notable changes to `@gamecult/cultcache-ts` are recorded here, following
 [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 
-## [0.15.0]
-
-0.14.1 and 0.14.2 were never tagged or published; this entry carries them with the Unreleased work, and `cultcache-ts-v0.14.0` is the previous release.
-
-### Breaking
-
-- A single-file store written as `cultcache.store.v3` is read and written: a record that holds an element id (an owned list element with an `[CultElementId]` member, carried through every write) marks the store v3, and a v3 store is carried through a rewrite with its ids. A runtime from before this change refuses a v3 store by name.
-- A single-file store refuses a zero-byte file as `StoreUnreadableError`; only a path with nothing at it is an empty store. A header this runtime does not read is refused, and the refusal echoes the header only as `cultcache.store.v<digits>`.
-- A write over a file the reader refuses (`StoreUnreadableError`, from `push`, `pushAll` and `delete`) refuses and leaves the file as it is. A flush used to replace such a file. A write set cannot merge with a disk it cannot read, so the file is repaired or removed by its owner before the store writes again. A full `pushAll` over a file with no readable stamp does not replace it: the reader refuses it. The stamp rule has one owner, `refuseUnreadFormat`, asked only by the one reader that every write consults under the lock. The reader judges the stamp from the header before it decodes the body, so a newer store is refused by name whether or not its body is whole.
-- A dangling symbolic link at the store path is an I/O error with code `ENOENT`, not an empty store.
+## [0.14.2]
 
 ### Added
-
-- `@gamecult/cultcache-ts/browser`, also what a bundler resolves for the package root under the `browser` export condition: the root surface without `SingleFileMessagePackBackingStore` and `readSingleFileStore`, so it imports no `node:*` built-in and no `koffi` and bundles with esbuild `platform: "browser"`. The Node entry exports exactly what it did.
-- `readSingleFileStore(path)`, the one synchronous reader of a single-file store, for consumers that must read a store file rather than decode it themselves. `pullAll`, `push`, `delete` and `pushAll` ask the same reader.
-- `StoreUnreadableError` for a store file this runtime cannot read, `SchemaConflictError` for a write the catalog cannot describe, and `schemaIdentityOf` with its result type `CultCacheSchemaIdentity` (`schemaId`, `schemaName`, `schemaVersion`, `compatibleSchemaIds`), the one derivation of a definition's identity.
-- The document payload codec, exported from `@gamecult/cultcache-ts/document`: `decodeDocumentPayload`, `encodeDocumentPayload`, and the two named byte escapes `documentPayloadFromBytes` and `documentPayloadBytes`.
-- `SingleFileStoreRead`, exported: the result type of `readSingleFileStore` (`absent`, `format`, `envelopes`, `repairedLegacyPayload`).
-- `CultCacheInspection.format` is `StoreFormat | "legacy.envelope-array"`: it reports `cultcache.store.v3` for a v3 store.
-- A soft `pushAll` writes only where nothing is at the path, leaves a store it can read byte for byte, and refuses what the reader refuses.
 - `SingleFileMessagePackBackingStore` takes a cross-process write lock on `<file>.lock`,
   interoperable with the C# and Rust runtimes (`flock` on Unix, `LockFileEx` on Windows).

-  random `p` (a 64-unit cube), a uniformly random `side` direction and offset, the

 ## [Unreleased]
 
-### Added
-
-- `math.fbm(float3 p, int octaves, float lacunarity, float gain)` and `math.fbm(float3 p)` (four octaves,
-  lacunarity 2, gain 0.5): the value-only octave sum of `snoise`, the cost of `fbm_grad` without the gradient.
-  The shaders carry `cultmath_fbm` in HLSL and GLSL; octaves clamp to [0, 16] as `fbm_grad`'s do.
-
-## [0.5.0]
-
 ### Breaking
 
 - `CultPhasor.cos` and `.sin` are now `.cosine` and `.sine` in C#, HLSL and GLSL,
   constructor parameters included, because SPIRV-Cross renames members that match
-  GLSL builtins.
-- The `const` `math.SNOISE_HESSIAN` (and `CULTMATH_SNOISE_HESSIAN`) is re-pinned
-  from 56.050385 to 55.642143, measured on the analytic `snoise_hessian` instead of
-  central differences of `snoise_grad`, whose rounding read high
-  (`NoiseBoundTests`). A consumer compiled against 0.4.x keeps the old value
-  inlined until it recompiles. `af_snoise` and `af_fbm` read it, so their
-  remainder terms are slightly tighter.
-
-### Changed
-
-- The package license expression is `MIT AND MPL-2.0 AND Apache-2.0` (was
-  `MIT AND MPL-2.0`): the Cycles files below are Apache-2.0 (`LICENSE.md`,
-  `THIRD-PARTY-NOTICES.md`).
-
-### Added
-
-- Cycles node semantics (Apache-2.0, `math.Cycles.cs` and the new
-  `Shaders/CultMath.Cycles.hlsl`): `math.cycles_*` and `cultmath_cycles_*` compute
-  what Blender's Cycles computes for the Math node operations whose results differ
-  from a plain intrinsic (`cycles_divide`, `cycles_power`, `cycles_modulo`,
-  `cycles_wrap`, `cycles_pingpong`, `cycles_smooth_min`, `cycles_arctan2`, ...),
-  Map Range (`linear`, `stepped`, `smoothstep`, `smootherstep`), Clamp, Mix
-  (`cycles_mix_float`, `cycles_mix_vector` and every colour blend mode as
-  `cycles_mix_<mode>`), RGB to BW, HSV conversion and `cycles_ramp_index`.
-  `CyclesOracleTests` holds the C# and the HLSL mirror to fixtures recorded from
-  Blender 5.2.2's CPU Cycles.
-- `CultMath.Expr`: an immutable scalar SSA expression graph (`ExprGraph`, built by
-  `ExprBuilder` with substitution, validated by `ExprGraph.Create` on build and on
-  decode), parameter bindings (`ExprBindings`), an evaluator (`ExprEvaluator`) and
-  the op table (`ExprOps`). The package carries no serializer for it.
-- Site cells: `math.power_score`, `multiplicative_score`, the `CultSiteCells`
-  accumulator (`site_cells_empty`, `site_cells_insert`, `site_cells_border`), the
-  exact power cell border (`power_border`, `power_border_step`) and
-  `gabriel_margin`, each with an HLSL twin (`cultmath_` prefix); the shader
-  `cultmath_power_border` takes a fixed-capacity site array of
-  `CULTMATH_MAX_SITES` (128 unless defined before the include). `power_cells`,
-  `multiplicative_cells` and `soft_gabriel_gate` are C# only.
-- Weighted lattice cells: `math.weighted_lattice_cells` with an exact ring-exit
-  search and its four public steps (`lattice_site`, `lattice_weight`,
-  `lattice_distance`, `lattice_smooth_step`), the range constants
-  `LatticeMaxBoost`, `LatticeMaxStretch`, `LatticeMaxSmoothing` and
-  `LatticeMaxRing`, and the HLSL twins (`cultmath_weighted_lattice_cells`,
-  `cultmath_lattice_cell_distance`).
-- Span stages: `math.span_fbm` and `span_ridged` over a `SpanPath` and a
-  `SpanStage` return `SpanNoise` (field, curvature and fold), widened by float
-  rounding allowances, with HLSL twins; `cultmath_span_rounding` and
-  `cultmath_span_slack` own the allowances.
-- `math.snoise_hessian(float3)` (`float3x3`), the next-order bound
-  `SNOISE_THIRD` (535.8009), and the snoise read rounding constants
-  `CULTMATH_SNOISE_READ_VALUE` and `CULTMATH_SNOISE_READ_GRADIENT` in HLSL.
-- `math.integral_clamp_linear(a, b, lo, hi, t0, t1)`, the integral of
-  `clamp(a + b t, lo, hi)` over `[t0, t1]` in closed form, with its HLSL twin. It
-  is finite for an infinite clamp bound, and `lo` above `hi` clamps to `hi`
-  everywhere, as `clamp` does.
-- `math.segment_closest` and the out-free `distance_to_segment` for `float2`
-  and `float3`, with HLSL twins.
+  GLSL builtins. This is a minor bump on 0.y.z, so the next cultmath-unity release
+  is 0.5.0.
