From 0d2645d056800cebd8694cc8ccd75ac997e6ad1e Mon Sep 17 00:00:00 2001 From: x Date: Tue, 29 Sep 2026 12:31:12 +0200 Subject: [PATCH 0001/1146] CultCache: element ids on every object-list element (C2a) [CultElementId] marks a string member; the registry refuses a document type whose list element type (union bases included) lacks one, naming the type and member. A write mints a random 12-hex id for each unset id and refuses a duplicate within one list. A store written before ids loads with ids minted in memory from SHA-256(record key, element path), so every reader and every reload agrees; they persist on the store's first write. CultCache.MintElementIds() rewrites the records whose ids exist only in memory. CultLib's own list-element types gain an id (Geometry, Mesh body, discovery, entity prefab). CultMeshCdnChunkRef and the CultWitness* elements are pinned by cross-runtime vectors and are left alone; see the C2a report.

Every object type below sits in a list (`List`, `T[]`, `IEnumerable`, 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\` 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. + + +## Aetheria (13 element types) + +- BehaviorData

From ded54365696deba1125bbe188306cb34d1308bbe Mon Sep 17 00:00:00 2001 From: Meta Vens Date: Tue, 29 Sep 2026 15:03:09 +0200 Subject: [PATCH 0003/1146] CultCache: derived element ids; the CDN chunk ref carries one [CultElementId(nameof(Member))] declares an id derived from that member's invariant text, never random, so content-addressed elements keep encoding to the same bytes. CultMeshCdnChunkRef derives its id from Offset; PackArtifact sets it, the Rust pack_content writes it, and the committed content vectors are re-cut once so both runtimes carry it. Engine tests drive Problems and Assign directly (InternalsVisibleTo the Caching tests).

A load refuses what a write refuses. Apply and Undo make minting part of the admission: a refused or uncommitted write leaves the caller's documents as they were. Override values mint inside Resolve, into the decoded copy, so the public CultVariantOverride.Set, C1-era overrides and Override() all get ids on write and on load; Override() no longer mints. Interface unions are judged on their concrete types, the same rule registration and minting share, and a subtype reusing the id's key is refused at registration. Dictionary keys format with the invariant culture. Records minted at load are marked per entry (IdsInMemoryOnly) instead of listed by key, so a deleted record leaves the mark with it, and a flush of the whole store clears it. A store whose types reach an object list declares cultcache.store.v3 (directory: v5), which every reader older than ids refuses; a marked file stays marked when a writer merges onto it.

The directory manifest's header choice moves beside FormatFor.

A writer that rewrites the whole store decides by content; a writer that touches part of it keeps a header already marked. Flush, unconditional and conditional commit, the directory store and CultMesh's single-file write all call it. A typed CultMesh write replaces the file with a document it can see, so it decides by content; a raw payload is opaque and keeps a marked file marked. A record's HoldsIds is what its stored form persists: a load keeps a variant's delta as read, so the ids a load mints in an override exist only in memory and no longer mark the store. A conditional commit onto the file no longer reads this cache's view of what the file held, so a stale view cannot over-mark it. IdPlan.HoldsIds is derived from HeldIds and the fills. Reverts InternalsVisibleTo GameCult.Caching.MessagePack and the public DirectoryFormatV4/V5 constants: the directory store reaches the decision through the protected member it inherits.

HoldsIds now has one owner, the record's stored form, read when asked: - a plain record: CultElementIds.Holds over its document, a scan that reads and refuses nothing; - a variant: the same scan over each override value, decoded with the codec the record was built with (the cache's, or the attached cache's at load); - a variant built with no codec (a store that loaded it with no cache) cannot see its values and counts as holding an id, so a store never writes an unmarked header over ids it could not see. Cut: the admission path that set HoldsIds on plain records, on variants from their resolved copies, and on flattened records; the internal setter and its backing flag; IdPlan.HeldIds and IdPlan.HoldsIds. The Mesh typed write reads Holds off the document it writes. Admission keeps its own id counting (IdPlan.Count) for IdsInMemoryOnly. Tests: an id added to a committed or loaded deck after admission marks a PushAll v3, and taking it away unmarks it; a variant read without a codec counts as holding ids while the same record read with one does not.

The rule, one per runtime: a file is a store on rewrite only when it is exactly one complete MessagePack array. Bytes after it, a value that is not an array, and a first slot that is a string but not a header this runtime reads are refused, and the file is left untouched. An empty file and a legacy envelope array (first slot not a string, empty included) carry no header and are still rewritten. - C#: ReadStoreHeader refuses non-array values, trailing bytes and a non-header first string, with a NotSupportedException naming which. - TypeScript: storeHeader (store-format.ts) decides the rewrite header; @msgpack/msgpack's decode already refuses trailing bytes. - Rust: store_header(bytes, whole) walks with a cursor; the rewrite path asks for the whole file, the read paths keep reading as before. - Python: push_all already reads the whole file (unpackb refuses trailing bytes, the legacy decoder refuses anything but a list of maps); pinned by a test. Tests in each runtime run the same file matrix (truncated, trailing, scalar, map, string first; empty, empty array, legacy), plus a C# unconditional commit over a store with trailing bytes and the C# Mesh raw write.

C# drops ReadStoreHeader (a second, header-only verdict that let a flush replace files the reader refuses) and asks DeserializeSnapshot from open, flush and commit; the reader now requires exactly one array, so C# refuses bytes after the store on read as TS and Python do. A zero-byte file is an empty store for all three paths. CultMesh.WriteSingleFileDocument reads the file it replaces through the Mesh reader before writing. Rust reads and rewrites through one classification (trailing bytes refused on read; a non-store first slot must be a legacy envelope array the reader accepts). TypeScript checks a legacy array with pullAll's own decoder before replacing it. Python already conformed. Shared byte vectors and per-runtime verdicts live in tests/vectors/document-variants-c2a/readability; every runtime's test reads them. Holds gains second-dictionary-value and second-list-item cases. The persistence format contract now marks v3 by content and states the readability rule.

Writers (C#, TypeScript, Python) merge same-id entries only when their schema names match; another schema's entry is dropped or the record gets a default entry under its own id, and a record's own id is claimed before an entry that lists it as compatible. The C# single-file writer prefers the entry being written now, as the directory writer does, so name, content hash and members come from the registered schema and the compatible ids are the union. Vector: compatible-before-owner-v3. A cultnet-py test's schema path no longer depends on the working directory.

A registered descriptor wins over an arrived entry with the same own id. Entries are written as chosen, with no union of compatible ids and no dependence on arrival order; an entry no record needs is not written. Two entries of one tier that share an own id and disagree on the schema name, records of different types under one id, or a record no chosen entry publishes refuse the write with a typed error (CultSchemaConflictException, SchemaConflictError) naming the id, the names and a record key, and the store is left as it was. CultSchemaCatalogEntry.MergeById and the Python and TypeScript merge paths are gone. A cache-held record unchanged since the file was read is rewritten under its registered id (C# single-file and directory), so an entry that lists an older id is not needed to publish it.

a schema renamed under a stable id opens, and an id that names one document is not overruled by a name that names another. The name resolves a record only when no local document has the id. The writer refuses a write that would change which type an existing record resolves to, unless the entries of both the existing records and the written ones own the id (a rename, the registered descriptor wins).

It could overwrite a record another writer changed while keeping its storedAt. A commit onto a file now writes its batch and leaves every other record as the file holds it; a record under an id only an arrived entry lists is refused, typed, with the file left as it was. Deleted the directory store's _durableCatalog, a second stale-able source of arrived entries beside the manifest read under the lease. Tests: the lost-update probe, the two refusals that replace the restamp tests, the arrived-overwrites-registered guard in both id orders, the content-hash tie-break against the compatible-list order, and refusal determinism across record arrival order.

The registered catalog entry lists the ids after its own, the registry resolves a record under one to the type (its own id first, then the first registered type that declares it), and a condition on a record compares schema ids through that resolution, so a record still under a declared old id counts as the record the cache holds. The cache already stamps every record it writes with the descriptor's own id; the store writers still change no identity, so a record a commit does not rewrite stays under the id the file holds it under, published by the registered entry. Without the declaration such a commit is refused, typed, as before. Contract and XML docs describe the declaration.

Expect, ExpectUnchanged, the reload and merge identity checks compare (StoredSchemaId, storedAt) with the store's bytes exactly. CanonicalSchemaId is deleted: canonicalising the disk id let an older version's whole-view rewrite (same storedAt, restamped to its own id, a member shed) pass a newer cache's condition (Soul F1), and failed every condition on a record resolved by name or through a file entry listing the local id (F3).

TypeScript already refuses this (cult-cache.ts); before, C# kept whichever type registered first (Soul F4). An exact wire alias must now also declare the same compatible ids: a type differing only in its declaration had it dropped when it registered second (H4), and is refused the same way. Exact aliases that agree in every respect still register by type, and a record under their shared id still resolves to the first registered (H3). Removing that would delete CultMesh's same-schema aliases; it is left for an operator ruling. Tests: both registration orders for a shared compatible id, an owned id declared by another type, and a same-schema type with a different declaration; an alias with the same declaration still registers. The registry tests use the shared EmittedDocumentTypes helper in place of their own.

a second claimant is refused typed register_document_type refuses a document whose own or compatible ids overlap another registered document's, raising SchemaConflictError (empty record key, both schema names, a message naming both document types), as TypeScript does. Before, the record resolved to whichever document the dict held first (Soul F4). With one carrier per id, resolution by id is a single pass. SchemaConflictError takes an optional message for this use. The test that pinned owner-over-lister resolution inside one cache becomes a refusal test in both orders; shared compatible ids and a shared own id (neither declaring its own) are refused in both orders.

A single-file whole-view write (plain flush, or an unconditional commit) re-encoded every record under its own type's id with the storedAt it loaded, so the pair could name two byte strings: v1 shed a member keeping storedAt, a second v2 cache restored v2's id keeping it again, and a v2 cache holding the original bytes committed its condition (Soul F6, A-B-A). Now such a write stores a record under a later storedAt whenever it stores it differently: under another id than it was loaded under, or with other bytes than the file holds at that storedAt (a record written with the ids it minted at load, for one). A record stored exactly as the file holds it keeps its storedAt. The store's entries and the cache's take the id and storedAt the write gave them. Tests: the A-B-A through commits and through plain flushes, with Expect and ExpectUnchanged; a flush that re-encodes a record restamps the cache that flushed (a condition holds straight after, SM12); a record stored unchanged keeps its storedAt through commits and flushes; persisting load-minted ids gives a later storedAt. The rolling-deploy test asserted v1's rewrite kept storedAt; it now asserts a later one, since that rewrite is a new store of the record.

The rule is now owner beats lister. A type owns its own schema id; any number of types may list an id as compatible beside its owner, registering in either order. A record under an id resolves to its owner, else to the one type listing it. An id no type owns and several list names no single type, so a record under it is refused, typed (CultSchemaConflictException naming the id and the listers), where it resolves: refusing at registration would depend on whether the owner had registered yet. A second owner of one id is still refused at registration, typed. A schema id hashes the schema's name and version, so the only second owner is a type of the same name and version, which the name-and-version check already meets; the separate own-id lookup could never fire and is gone. Tests: an owner and a lister register in both orders, the owner's id resolves to the owner, the lister's own id to the lister, and without the owner to the lister; two listers register in both orders, a record under their id is refused typed with no owner and resolves to the owner with one, registered before or after them; a cache with v1 beside v2 reads each version's records as its own type, in both registration orders. The emitted-fixture note says why a fixture is emitted now that v1/v2 pairs no longer need hiding from the shared registry.

A document owns its schema id; others may list it as compatible beside its owner, in either registration order (batch 9 refused any overlap, which forbade keeping v1 beside a v2 that declares v1's id; Soul F8). A record resolves to the document owning its id, else to the one document listing it. Several listers and no owner name no single document, and the load is refused with SchemaConflictError naming the id, the record key and the listers: refusing at registration would depend on whether the owner had registered yet. Every registration refusal is now SchemaConflictError (Soul F10): a second owner of one schema id, a second document with one schema name, and a second definition of one document type. Each names the new document's id and both schema names and document types. Before, the last two raised CultCacheError. Tests: an owner and a lister register in both orders and each reads its own records, and a lister alone reads the owner's id; two listers register in both orders, a record under their id is refused typed without its owner and is the owner's with it, registered before or after them; two owners, one schema name and one document type twice are each refused as a schema conflict.

The cache kept one definition per id, own or compatible, and refused a second with a plain Error, so a v1 definition could not stay registered beside a v2 declaring v1's id (Soul F8, cult-cache.ts registration). Now a definition owns its schema id and any number may list it: a record resolves to the owner, else to the one lister. Several listers and no owner name no single definition, and the load is refused with SchemaConflictError naming the id, the record key and the listers. Every registration refusal is now SchemaConflictError (Soul F10): a second owner of one id, a second definition with one schema name, and a different definition for one type. Each names the new definition's id and both schema names. SchemaConflictError takes an optional message for these uses. Tests: an owner and a lister register in both orders and each reads its own records, and a lister alone reads the owner's id; two listers register in both orders, a record under their id is refused typed without its owner and is the owner's with it, registered before or after them; each of the three refusals is a SchemaConflictError in both registration orders.

One type owns a schema, so a handle never needs presenting as another type for the same schema. Parity with C# 1e045502. - Delete asSchemaAlias from the document, bound document, collection and bound collection handles, and cultMeshSchemasAreCompatible, which only it and the catalogs' alias step used. - Document and collection catalogs answer a typed lookup from that type's handle or not at all. A descriptor without a type is still looked up by schema id, then schema name and version. The parse option on every catalog method existed only to convert an aliased value, and is deleted. - CultMeshNode passes the caller's definition to its cache. The node no longer resolves another type's definition by schema id, and no longer re-parses values into the requested type, so a type the node did not register is refused by the cache. node.get and node.put now return the cache's own value, as CultCache.get and put do. - Tests: the noteAliasDocument fixture is deleted. Tests that used it for publication, sync, snapshot, store and prediction paths now use noteDocument. otherTypeForNoteSchema stands for another type claiming the note schema: catalogs do not find it, and a node refuses it on every path and refuses to register it beside noteDocument. - README stops documenting node aliasing.

Catalog methods now take the schema argument as a type parameter: a CultCache document definition yields its own value type, an explicit type argument still wins, and a bare schema descriptor yields unknown. CultMeshCatalogValue names that rule. - Document catalog: tryDocument, document, latest, replace, submitPrediction, authoritativeWriter, predictionWriter, watch. Collection catalog: tryCollection, collection, latest, watchChanges. - The two copies of the (value, options) / (context, value) argument split collapse into cultMeshCatalogWriteArguments, and the typed lookups share one private #require per catalog. - Tests: the three reads that named their type infer it again. A type-level test pins inference for reads, rows, watches, writes and writers with @ts-expect-error on wrong assignments.

Nothing is bound on refusal. Binding a type to the schema id it holds again replaces the binding. - Call sites propagate the refusal: the cultmesh-rs registry macro, the interop peer example, and the tests. - Tests renamed to what they test: raw snapshot replication hydrates the receiver's own type for the schema; a reactive document coalesces direct member writes. - New test: both claimant shapes in both orders, the first binding intact afterwards, and a same-type rebind replacing.

The F2 principle (operator, 2026-09-30): "CultCache never destroys or relabels a record it doesn't understand; keeps it byte-for-byte, refuses writes that would overwrite it." - F1: the registry derives every binding's identity with cultcache-ts's schemaIdentityOf, so it stamps, refuses and resolves exactly as the cache does. P1 (A with schema name "p1.shared", B with schema id "p1.shared") is now refused by both. - F2a: an id nobody owns resolves to the one binding that lists it as compatible. Several listers and no owner is a SchemaConflictError naming the id and the listers, whatever order they were registered in; an owner beats every lister. This is refused at resolution, as the cache refuses it at load, not at registration: refusing at registration would make the outcome depend on whether the owner was registered before the listers. - F2b: version inference is deleted. "p3.note.v7" no longer resolves to the type named "p3.note" and gets relabelled "p3.note.v1". - F2c: a schema version string, and a schema name, are not ids. Snapshot filters, typed puts and deletes, and raw puts match only declared ids. - F3: a raw record under an id no binding declares is refused. The registry no longer tries each binding's parser and stores the record under the first that accepts it (P5: an identity parser registered first took everything). - The dead resolvePayloadSchemaVersion helper is gone. Tests: the three shape- and alias-routing tests are replaced by P1, P2, P3/P4 and P5 as behaviour tests. The one-type-per-schema test registers two bindings ahead of the holder (F6/M11).

The catalog-entry name/version match and both parse fallbacks are deleted: a record under another id is not this document, whatever its payload parses as. - Peer snapshots (F4): syncDocumentFromPeerSnapshot and definition-named peer-snapshot handles take the peer's record at the key under the type's schema id only. The shape filter is deleted and no match is not-found. P8a (syncing A at k while the peer holds only B at k overwrote the local B and then threw) and P8b (a peer's C stored as A) write nothing now. - HELD: a peer-snapshot handle named by a bare schema-id string still takes the first record at the key. Eve Electron reads the C# Aetheria daemon that way (EveElectron src/cultmesh-provider-client.mjs:129-142): the daemon stamps SHA-256 schema ids and the client asks by "gamecult.eve.provider_advertisement.v1", so only the fallback finds its records. How a TS reader names a C#-hosted schema is raised as a fork; the fallback goes when it is ruled. Tests: the store- and peer-snapshot tests that asserted shape routing are replaced by tests of the refusal, including P8a and P8b, and one that pins the held fallback.

A staged write, a commit (onto the file or whole view) and a whole view over a key the file holds as foreign refuse with CultSchemaConflictException naming the key and id. A merge judgement never decodes a foreign record, and one that replaced a held record takes it away. - Directory store: a foreign record's page is never read; a generation that would replace or remove one refuses before any page is written. - Contracts: hard rejection no longer lists "no compatible local schema candidate"; the persistence format says what a foreign record is.

The schema-identity probe showed a C# rewrite restamping every other runtime's record to its sha256 id and dropping their catalog entries. - The single-file store remembers, per key, a record it loaded under an id its type neither owns nor declares compatible (resolved through the catalog's schema name or an entry pointing at a local id), with the entry that published it. While the store still holds the entry it loaded, a whole-view write (flush or unconditional commit) lays that record back with its id, storedAt, bytes and catalog entry. A write of the record itself still stores it under the type's own id. - A record published by an entry under the type's own id is this schema's and is re-encoded as before (the registered entry wins its own id). - A laid-back record's load-minted element ids stay in memory only, so MintElementIds still rewrites it. - The rolling-deploy tests lose their premise: an older version's whole view no longer sheds a newer record's member. They now pin that it lays the record back and the newer cache's condition holds; the A-B-A test keeps F6's defence through an explicit older write. - Contract: the stamp and the lay-back rule in the persistence format.

[Test] From eae56189c653a3ba903f45461613dd38c2c03a7e Mon Sep 17 00:00:00 2001 From: Meta Vens Date: Wed, 30 Sep 2026 21:20:11 +0200 Subject: [PATCH 0117/1146] Rust: a write lays back the catalog entry the file holds for an id C2a F2, widened by Self. The schema-identity probe showed a Rust write replacing the C# catalog entry it read with a fabricated one: version "sha256:...v1", members [], canonical JSON naming the hash. - The store's one reader returns the file's catalog beside its envelopes. - The encoder writes back the entry the file holds for each id it writes (by own id, else a lister) and describes an id itself only when the file has none, or when a registered type owns the id under another name (a rename, whose rule is unchanged). - Test: a push and a whole-store push both lay back a C#-shaped entry byte for byte.

GlslMirrorTests pins the committed file to the lowering (CULTMATH_WRITE_GLSL=1 regenerates it), finds no HLSL-only token, finds every public function but the texture samplers, and pins fixtures/glsl-parity.json (256 seeded cases per family as float32 bit patterns) to C#.

Type names: `floatN`, `intN`, `uintN` and `boolN` become `vecN`, `ivecN`, + `uvecN` and `bvecN`. +4. File-scope `static const` becomes `const`. +5. C-style casts `(float)x`, `(int)x` and `(uint)x` become `float(x)`, `int(x)` + and `uint(x)`. The operand is found by a balanced-bracket scanner: + `(int)((state >> 28) + 4u)` nests parentheses. +6. Intrinsics are renamed: `lerp` to `mix`, `frac` to `fract`, `rsqrt` to + `inversesqrt`, `asuint` to `floatBitsToUint`, `asfloat` to + `uintBitsToFloat`, and `saturate(x)` becomes `clamp(x, 0.0, 1.0)`. +7. Float literals pass through unchanged. +8. The library is wrapped in a `CULTMATH_GLSL` guard. +9. The first line names the file as generated and says how to regenerate it. + +GLSL ES 3.00 is stricter than HLSL: no implicit conversions between int, uint +and float, no C-style casts, and no `step(genType, float)` overload. Those gaps +are closed in the HLSL, never in the lowering: the HLSL is written in the subset +both languages share, with edits that are legal HLSL and compute the same bits +(`step(h, float4(0.0, 0.0, 0.0, 0.0))` rather than `step(h, 0.0)`, `+ 4u` where +a uint is added, `(float)((uint)hash.x >> 8)` before a float multiply). The C# +mirror and the FXC and dxc compiles keep those edits honest. A body that needs a +transformation outside the list fails `GlslMirrorTests.NoHlslOnlyTokensSurvive` +rather than gaining a special case. + +The library declares no precision. The host shader does, and it must be +`precision highp float; precision highp int;`: the PCG hashes need 32-bit +integers. `tools/compile-glsl.ps1` writes such a wrapper (its own `#version +300 es` line, the precision, the library by string concatenation, and one call +of every public function) and compiles it with glslang, which +`tools/get-glslang.ps1` fetches pinned. The Unity package does not ship the +GLSL file. + +Parity runs in two legs, each with one owner: HLSL against C# by the mirror +test, bit for bit; GLSL against C# by the golden fixture, which records 256 +seeded cases per function family as float32 bit patterns, evaluated by the +consumer on WebGL2 and read back. Integer-only families (`pcg3d`, `pcg4d`) must +match exactly; float families are ulp-bounded, the bound measured on the device. +`iv_exp` is not in the fixture, because its C# bits come from the platform's +`exp`. + ## Invariant 8: Value-and-Gradient Primitives A primitive tagged invariant 8 returns its value and analytic gradient From 75ba6c0f5c5c6b673704d943365d1ad6445c4504 Mon Sep 17 00:00:00 2001 From: Meta Vens Date: Fri, 2 Oct 2026 20:49:12 +0200 Subject: [PATCH 0150/1146] Mesh: a zero-byte store file is refused, not read as empty; the alias test is retargeted to one type per schema CultMesh's single-file reader had its own zero-length-means-empty branch, so a Mesh write replaced a zero-byte file the cache refuses (merge-r1-precedence). It now asks the cache's snapshot reader and gets its verdict. The auto-merged test that read a same-schema instance through MeshNoteAliasDocument cannot be built under retire-schema-alias; it now states the ownership rule it protected (a database serves only what a shard owns) with the one type.

Aetheria warps only the noise argument (triNoise3d(pos + fl * ...)); the surface height is read at the unwarped xz and the displacement is applied to y afterwards. So the envelope is evaluated on the pre-distortion SDF over the unwarped slice (no D), and only the noise ball is enlarged by D (iv_frustum_ball's warp argument). A warp applied to the envelope's argument would be unsound without enlarging the box by D; the field is defined so that it is not. The test EnvelopeBoundEnclosesDensity pins this: 2,000 seeded slices x 64 warped points, the composed bound encloses density(p) with no tolerance (every op is monotone or already widened in r1; if a seeded case fails at an endpoint, widen in the implementation, never the test).", + "iv_frustum_ball(float2 centreSlope, float z0, float z1, float footprintPerDepth, float warp) -> float4(centre, radius), in C# and both HLSL copies, is the one new CultMath function: the noise ball of a tile over a depth segment. Camera: pinhole at the origin looking +z, focal length f pixels; a pixel's ray is p(z') = (m z', z'); a tile's slopes lie in m_c + [-N/(2f), N/(2f)]^2 (full footprint, so sub-pixel jitter is covered), s = N / (sqrt(2) f).

(2) Coarse probes were attempted where the ball could never prove emptiness: iv_snoise_ball's hi is n(c) + L r clamped to 1, so a probe with L r F0 >= 1 + cutoff is a guaranteed failure; at r1's StepMax = 2 that is L r F0 = 3.7, so every coarse probe was a wasted evaluation (the 0.74x row). r2 attempts a noise probe only when L * radius * F0 < 1 - (the cutoff the probe needs), otherwise the level is 'maybe' at no cost. (3) Growth was capped at StepMax = 8 Step0, so a ray through clear space paid Depth / StepMax probes; r2 grows to the remaining range (the hierarchy is over cell-index ranges, halving on maybe, doubling on skip, capped only by the grid's end).", + "(Review, continued.) (4) The dense sample evaluated the detail octave even where occupancy was 0; r2's dense sample evaluates coverage first and the detail only when the envelope and coverage leave density > 0, as Aetheria's `if (dist < _SafetyDistance)` does; the dense baseline gets cheaper and the comparison honest. (5) The finest-level probe before integrating a cell stays: amortized over the tile it costs 1/N^2 and can skip 3 snoise per ray. (6) The step never regrew after a dense cell until a skip; with (3) it regrows from the next skip, which is enough.", + "The march, on cell ranges.

MarchTile takes a range [j0, j1): the envelope probe over the slice (z_j0, z_j1); if empty, skip and double the next range; else if the noise probe is affordable (item 2) and proves empty, skip; else if the range is more than one cell, halve; else the cell is dense. It runs to the grid's end once per tile (a pre-pass does not know any ray's transmittance) and yields the dense cells; each of the N^2 rays integrates exactly those cells in order with the dense march's own Integrate and early-out at 0.02.

(b) inside the fog: h = 0, camera at y = F - 10, rays level, expected near 1x: every ray saturates within a few cells and the pre-pass still probes the whole grid.

The old main menu found in Aetheria e6181c11, site-ground r3, the void scenario in interval-ops r2 Ruling operator-ground-void-brush answers Q6 outside the options. The original main menu's brush, floor, sun, orbit, camera follow, authored light and stardust rule are read from Aetheria at e6181c11 and carried in their units; the lighting is the original's analytic pulse made 3D; the TAA reprojects by camera and flow; the saving test gains the void scenario and asserts 2x on it.

A warp applied to the envelope's argument would be unsound without enlarging the box by D; the field is defined so that it is not. The test EnvelopeBoundEnclosesDensity pins this: 2,000 seeded slices x 64 warped points, the composed bound encloses density(p) with no tolerance (every op is monotone or already widened in r1; if a seeded case fails at an endpoint, widen in the implementation, never the test).", "iv_frustum_ball(float2 centreSlope, float z0, float z1, float footprintPerDepth, float warp) -> float4(centre, radius), in C# and both HLSL copies, is the one new CultMath function: the noise ball of a tile over a depth segment.

(2) Coarse probes were attempted where the ball could never prove emptiness: iv_snoise_ball's hi is n(c) + L r clamped to 1, so a probe with L r F0 >= 1 + cutoff is a guaranteed failure; at r1's StepMax = 2 that is L r F0 = 3.7, so every coarse probe was a wasted evaluation (the 0.74x row). r2 attempts a noise probe only when L * radius * F0 < 1 - (the cutoff the probe needs), otherwise the level is 'maybe' at no cost. (3) Growth was capped at StepMax = 8 Step0, so a ray through clear space paid Depth / StepMax probes; r2 grows to the remaining range (the hierarchy is over cell-index ranges, halving on maybe, doubling on skip, capped only by the grid's end).", "(Review, continued.)

PushAll, CommitBatchCore (conditional and unconditional, one apply) and CultMesh's write call only it. Catalog entries read from a store keep their exact bytes and are written verbatim while their decoded fields are unchanged. Derive no longer lets a registered entry publish an id nothing staged sits under. HeaderForWrite is the one header rule for the single-file and directory stores. A write is judged against variants another writer left in the file. Tests of the deleted rules are rewritten in the next commit.

Mesh: a write copies neighbours forward and replaces only its key. The lay-back and whole-view tests and the flush-restamp tests are rewritten or removed with the rules they pinned.

the load-minted ids stay for MintElementIds after an unconditional write; a detached store marks the variant it writes, not the one it copies; a variant write supplies the indexed override; the conditional/unconditional comparison uses one batch (a conditional commit refuses staged writes by design).

A version is therefore the SHA-256 of the slice the file holds, whatever legal encoding its writer chose, not of C#'s re-encoding, and a write that copies a record leaves its bytes and so its version alone.

A decoded record or snapshot carries no stored bytes, so an in-place edit of its payload or overrides can never be shadowed by cached bytes, and the public snapshot and record serializers encode every record from its fields. SingleFileBackingStore now reads through ReadStore, which returns the snapshot and, parallel to it, the exact slice the file holds for each catalog entry and record. Its durable index keeps, by record key, that slice and its SHA-256 (hashed when a comparison asks), which is the record's version. A write re-encodes every record the writer staged and copies every other record, and every catalog entry it keeps, as the slice the file holds. The directory store keeps its manifest's catalog slices the same way. SerializeSnapshot/DeserializeSnapshot hooks become SerializeStore/ReadStore plus SerializeCatalogEntry. A staged but unchanged non-canonical record is now re-encoded canonically and gets a new version; an untouched one keeps its bytes and version. Tests: in-place edits through the snapshot API (payload, override) and through a held document (collection, nested object) are written as edited; an untouched non-canonical record survives a neighbour's write byte for byte; a staged one is re-encoded. The cost test counts record hashes.

The map's own rule says `(Rh, S)` are the +knobs, so the honest choice is the first; it changes the look relative to the +site section, hence Q9 (below). For `CARVE = 1.5` the ramp width is tied to the +exponent (`S/Rh = 1/√(1 − 1.5^(−1/e)) − 1`: `e = 0.4 → 0.25`, `e = 0.7 → +0.5`, `e = 1 → 0.73`, `e = 4 → 2.2`), so "pseudo-Gaussian" and "narrow" cannot +both be had without a third knob, and a narrow wall at `e = 4` needs +`CARVE ≈ 58`, which is a hard wall again.

ReadShaderSource takes an include predicate (one resolver); the C# mirror still inlines everything. GlslMirrorTests pins both files, checks tokens in each, takes the union of definitions and asserts cultmath_phacelle( and CultPhasor live only in the Phacelle file. The fixture appends cultmath_iv_frustum_ball (exact) and cultmath_iv_exp ("ulp-bounded, platform exp", platform named); the comparison is per family, the platform family within 1 ulp with the maximum printed. THIRD-PARTY-NOTICES lists CultMath.Phacelle.glsl, not CultMath.glsl, as MPL-2.0. Regenerated on Yggdrasil (Ubuntu 24.04.5, .NET 10.0.12); 286/286 green, iv_exp within 0 ulp.

frustum enclosure check, the phacelle family's evaluator, sqrt on GLSL The parity section states the enclosure rule, restores that the evaluator concatenates CultMath.Phacelle.glsl for the phacelle family, and names CultLib's browser-pane run (follow-up gpu-snoise-parity) as that evaluator. The frustum-ball bound no longer assumes a correctly rounded GLSL sqrt: proven for C# and HLSL, measured on GLSL.

Premises of the sketch, checked against definitions + +- **[fetched] + [derivation]** Simplex noise kernel degree. Gustavson, *Simplex noise + demystified* (2005), gives the 3D reference code. Each of the four simplex corners + contributes `t^4 * dot(g, d)` with `t = 0.6 - |d|^2`, and the contribution is zero + when `t < 0`. On a straight ray `d` is affine in the ray parameter, so `|d|^2` is + quadratic and each corner term is a polynomial of degree 8 + 1 = 9. The pieces have + two kinds of breakpoint: the simplex faces the ray crosses (where the corner set + changes), and the entry and exit of each corner's support sphere (`|d|^2 = 0.6`). + Both kinds are roots of polynomials of degree 2 or lower in the ray parameter, so the + breakpoints are closed-form. With the 0.6 radius, the support extends past the + simplex, and the reference code truncates it at the simplex boundary. The resulting + small discontinuity across faces is a known property of that constant. It does not + change the piecewise-polynomial structure. +- **[derivation]** Classic Perlin noise (Perlin 2002 quintic fade `6t^5 - 15t^4 + 10t^3`, + read in Gustavson's text **[fetched]**) is, within one lattice cube along a straight + ray, a polynomial of degree 3 x 5 + 1 = 16. Its breakpoints are the cube faces. +- **[fetched]** Piece count grows with frequency. Balint (CESCG 2019, section 2) + states that many noise functions are piecewise integrable, but the number of pieces + is linear in the noise frequency. Their cost is therefore similar to numerical + integration. Balint designed cosine noise to escape this limit (section 1.1 below). +- **[derivation]** For the clamp `max(0, n - c)` on a degree-9 or degree-16 piece, + the roots of `n - c` are needed. Polynomials of degree 5 or more have no general + closed-form roots (Abel-Ruffini), so the clamp needs numerical root isolation per + piece, for example Sturm sequences, Descartes' rule or Bernstein-basis subdivision. + The integral between the isolated roots is closed-form. + +## 1. Closed-form line integrals of noise, and analytic optical depth + +### 1.1 Cosine noise: Balint, *Closed Form Transmittance in Heterogeneous Media Using Cosine Noise*, CESCG 2019 (non-peer-reviewed) + +- **[fetched]** It computes noise defined as an offset plus a sum of cosines of + `x . S_i`. The paper uses 24 quasirandom vectors S_i, with Sobol directions on the + sphere and lengths in [0.8, 1.2], to look roughly like Perlin noise. Fractal octaves + are further cosine sets. Its line integral is a sum of sines, so the optical depth + over any segment is exact. The paper says this takes two noise samples, one at each + segment end. It also gives closed-form distance sampling, by inverting the integral + with binary search. +- **[fetched]** Cost: two noise-sized evaluations per segment, independent of octave + count. Table 1 reports transmittance evaluation at 179 ms closed-form against + 1250 ms for delta tracking, about 7x faster. A real-time demo with 16 samples ran + at 80 fps at 675 x 1200 (RTX 2080 Ti). +- **[fetched]** Error: exact, with no error term, for the bare sum. The limits are + stated in section 6. Multiplying by a shape function, or composing with a shaping + function, generally destroys the elementary antiderivative. The workarounds + recover exactness only piecewise: constant multipliers between bounding isosurfaces, + or a cubic polynomial interpolant of the multiplier along the ray, since the product + of a polynomial and cosines has an elementary antiderivative. Negative densities from + a low offset are handled by clamping samples and integrals, which is not an exact + `max(0, .)` integral. Domain warp is not discussed. + +### 1.2 Gabor kernels: Condor, Hermann, Yurtsever, Didyk, *Gabor Fields: Orientation-Selective Level-of-Detail for Volume Rendering*, ACM TOG 45(4) art. 62, 2026 (arXiv 2602.05081) + +- **[fetched]** It computes closed-form definite line integrals of anisotropic 3D Gabor + kernels along an arbitrary ray segment (eq. 9). Each kernel is whitened into its + canonical space with a ZCA matrix, so any covariance, that is any affine-transformed + kernel, uses the same formula. The segment integral is the real part of a + complex-erf (Faddeeva) difference. +- **[fetched]** Cost: the complex erf is evaluated by a truncated Taylor series with + early exit, capped at 16 terms. Segments shorter than 1e-4 in whitened units fall back + to a single midpoint evaluation. Kernels are spatially clamped with an adaptive extent + that shrinks with frequency (eq. 15). The paper also renders procedural clouds as + Gaussians modulated by Gabor noise. +- **[fetched]** Error: each segment integral is exact apart from the erf truncation. + Orientation-selective masking of kernels whose line integral is near zero trades a + small error, or variance under stochastic selection, for speed. The paper reports + about 1.78x to 1.96x speedups. Per segment the density-integral estimator is + unbiased, but transmittance is biased by Jensen's inequality.

The volume rendering integral of + each linear segment, through an arbitrary nonlinear transfer function, is then one + lookup in a table indexed by front scalar, back scalar and segment length.

It computes a sparse-convolution noise of Poisson + impulses with Gabor kernels. Each kernel is a Gaussian in frequency, so filtering with + a Gaussian pixel filter multiplies Gaussians, which gives an analytically filtered + kernel. Cost: the paper typically uses 100 impulses per kernel, or 25 to 50 at lower + densities. Table 2 (GTX 280) reports, at 20 impulses per cell, 290 fps for 2D noise, + 111 fps for unfiltered surface noise and 50 fps for filtered surface noise.

The site does not vendor the MPL file and skips the family. +Its evaluator is the cultmath-tapes follow-up `glsl-browser-parity-run`, owned +by the next CultMath parity cut: a repeatable CultLib WebGL2 run of every +fixture family, `phacelle` included. Until it lands, the one GLSL evaluation of +`phacelle` is a single probe (GTX 1070, ANGLE D3D11: within `3.1e-6 max(|v|, 1)` +of C#). Asura's `gpu-snoise-parity` is a different check, an FXC and Unity +readback of `snoise`, and evaluates no GLSL. ## Invariant 8: Value-and-Gradient Primitives From 5b1f94dec72be46580375b4a94eabb6b46f2302d Mon Sep 17 00:00:00 2001 From: Meta Vens Date: Sat, 3 Oct 2026 14:36:52 +0200 Subject: [PATCH 0264/1146] Research: analytic noise integration feasibility probe (cultmath-tapes) Measured on the shipped void and the Aetheria wells at warp 60: affine warp spans, simplex cells and lattice points per span, exact-against-march cost and error per octave, high-octave variance, clamp crossings and transmittance error; plus Aetheria's triangle noise.

This is a measurement, +not a spec. The tape target stays parked under ruling +`cultmath-tapes:ruling:tape-target-unparks-when-asura-stable`. + +**Verdict.** Exact integration of the noise does not beat sampling for optical +depth on either shipped field. +- The exact line integral of CultMath `snoise` is cheap and correct. Affine warp + spans are long, at 100 to 300 world units. +- The exact noise integral is not the optical depth, because both densities are + nonlinear in the noise. + - The void's wall profile is `pow(·, 0.40)` with two clamps. + - Aetheria's fog is clamped at zero and goes opaque within a few world units. +- Given the *exact* span mean of the noise for free, the resulting transmittance + is still 3.6x worse than the shipped march on the void and 22x worse on the + wells. +- Exact integration wins only on the linear functional `∫ n dt` of octaves the + march undersamples. That gain does not survive the density's nonlinearity. +- Aetheria's triangle noise is integrable exactly as piecewise linear, but costs + 3x to 22x the march, and its shipped form does not meet the preconditions. + +## Scenarios and method + +- **Void:** the shipped void (`NoiseBoundTests.VoidField.Shipped()` at + `hands/cultmath-interval-ops` 2c8585bd). + - Rh 198, S 50, Rc 248, K 1/30, A 20, F0 0.01 (cells of 100 and 25 world), warp + D 10. + - The shipped orbiting camera, N = 8 tiles at f = 935, one jittered pixel ray per + tile. +- **Wells:** the test's Aetheria wells at warp D = 60 (`FogField.Wells(60)`). + - F0 1/414.2167, A 20, B 10, extinction 0.5, flow frequency 1/512, period 8. + - Like the test, this uses the snoise field shape (r1's), not Aetheria's own + triangle noise. Triangle noise is measured separately below, on the same rays. +- **Rays:** 200 per scenario, and 120 for the triangle basis. + - The wells give 147 rays with an active interval; the rest look up and miss + the fog. + - The active interval is where the envelope leaves the density to the noise. + It is cut where the true optical depth reaches 6. + - Active length per ray: void median 140 world (p10 114, p90 193); wells median + 268 (p10 137, p90 623). +- **March steps:** the void's march step (LodStep, 12.5 in z) is a median 14.9 + world along the ray. The wells' quadratic grid gives a median of 9.1 in the + active region. +- **Warp:** `w(p) = flow(p) · shift`, so the affine error scales exactly with + `|shift|`. + - Spans are grown at the worst phase shift, Period / 2. A span is therefore + valid at every frame's phase, for any camera that crosses the same world + segment. + - Each span is anchored at p0 with J·d from a central difference. It grows in + 1-unit (void) or 2-unit (wells) steps until `|w − (w0 + J·d·Δ)| > τ`. +- **Exact simplex integral:** CultMath `snoise(float3)` has kernel radius² 0.5, + so its support never leaves the incident simplices. + - Along a line it is therefore a sum over the lattice points within √0.5 of the + line. Each point contributes `∫ (0.5 − |x|²)� (g·x) dt` on its chord, a + closed-form degree-9 polynomial. + - Validation: + - The lattice sum matches `snoise` within 2e-4 (float32 rounding at + coordinates near 300). + - The segment integral matches a 5e-4-step quadrature within 2.5e-5 per + unit length. +- **Run:** probe code was in a scratch clone (probe-clone@91c8cbf1, never merged) + and ran on Yggdrasil through the verify stopgap, in a dotnet 10 container with + 4 CPUs. Timings are single-threaded C# on that host and are relative. + +## 1. Affine-valid span length (ray length, world units) + +| τ (× coverage cell) | Void p10 / median / p90 | Wells p10 / median / p90 | +|---|---|---| +| 0.05 | 94 / 129 / 211 | 71 / 103 / 169 | +| 0.10 | 141 / 197 / 324 | 108 / 151 / 253 | +| 0.25 | 263 / 420 / 1244 | 184 / 275 / 715 | +| 0.05 × detail cell | 44 / 63 / 97 | 34 / 47 / 75 | + +- One affine span at τ = 0.1 covers about 13 void march steps and about 16 wells + march steps. +- The void shell is shorter than one span. The tiled spans are clipped by the + active interval, at a median of 27 world and 2 spans per ray. +- On the wells, the tiled spans run a median of 128 world, with 2 per ray (p90 4). +- The tangent anchor is the worst affine choice. A secant or Chebyshev fit over + the span cuts the error bound by 2x to 8x, so the spans could be about 1.4x to + 2.8x longer at the same τ. That was not measured. + +## 2. Simplex cells per span, per octave + +Octave `xm` is the coverage octave's frequency times m, warped like the coverage +octave. The shipped detail octave is x4 and is *unwarped* in both fields, so it +needs no affine span at all. + +Counts are for τ = 0.1 tiled spans with both warp phases, given as the median and +then the p90. The rows are simplex cells crossed, then lattice points touched, +which is the exact work. + +| Octave | Void cells | Void lattice points | Wells cells | Wells lattice points | +|---|---|---|---|---| +| x1 | 6 / 16 | 10 / 16 | 4 / 8 | 8 / 10 | +| x2 | 8 / 27 | 10 / 26 | 8 / 12 | 10 / 14 | +| x4 | 13 / 52 | 14 / 44 | 12 / 20 | 14 / 20 | +| x8 | 20 / 100 | 20 / 80 | 22 / 38 | 22 / 34 | +| x16 | 40 / 201 | 35 / 154 | 44 / 72 | 38 / 60 | +| x32 | 75 / 396 | 62 / 302 | 86 / 144 | 70 / 112 | +| x64 | 151 / 793 | 118 / 592 | 172 / 287 | 132 / 218 | + +- On the same spans, the march takes a median of 2 samples per span on the void + (p90 10) and 12 on the wells (p90 25). +- A straight line touches 3.44 lattice points per noise unit. + +## 3. Cost: exact against the march + +- **Measured cost.** + - One snoise is 530 to 610 ns in C# on this host. + - One lattice-point integral (hash, gradient, closed-form polynomial) is + 85 ns, or 0.16 snoise. + - With this probe's naive box-scan enumeration it is 1.24 snoise. That is an + upper bound; a simplex walk visits only crossed cells. +- **How the table counts.** Exact is lattice points × 0.16 + 1 snoise per span + for the Jacobian. March is 1 snoise per sample. Both sides carry the two warp + phases. +- **Tolerance.** τ is 0.1 × *that octave's own* cell, so the affine error is + comparable across octaves. +- **Columns.** The two error columns are RMS errors of the active-length mean + of one warped octave. The last error column is what replacing the octave by its + expectation of 0 costs. + +| Octave | Void exact/march cost | Void err exact / march / expectation | Wells exact/march cost | Wells err exact / march / expectation | +|---|---|---|---|---| +| x1 | 0.36 | 1.1e-2 / 1.6e-3 / 0.21 | 0.11 | 1.9e-2 / 9e-5 / 0.29 | +| x2 | 0.46 | 1.0e-2 / 4.7e-3 / 0.13 | 0.15 | 1.5e-2 / 2e-4 / 0.21 | +| x4 | 0.68 | 9.0e-3 / 4.0e-2 / 0.10 | 0.23 | 1.1e-2 / 5e-4 / 0.18 | +| x8 | **1.03** | 5.8e-3 / 8.0e-2 / 0.067 | 0.36 | 7.2e-3 / 1.1e-3 / 0.10 | +| x16 | 1.64 | 4.0e-3 / 9.0e-2 / 0.050 | 0.56 | 6.4e-3 / 9.4e-3 / 0.088 | +| x32 | 2.89 | 2.8e-3 / 0.105 / 0.036 | 0.87 | 4.7e-3 / 3.3e-2 / 0.057 | +| x64 | 5.26 | 2.0e-3 / 0.095 / 0.025 | **1.44** | 3.2e-3 / 5.3e-2 / 0.040 | + +- **Where exact stops paying on cost:** + - At the measured kernel cost: x8 on the void and between x32 and x64 on the + wells. + - At the brief's model of one snoise per cell crossed: about x1 to x2 on the + void and x8 on the wells, from the per-span table in the probe log. +- **Exact against the march on accuracy:** + - At the shipped step the march is *more* accurate for octaves it oversamples: + void x1 to x2, wells x1 to x8. The exact path's error floor is the affine warp + error, about 1e-2 at τ = 0.1 per cell, and it scales with τ. + - Exact is more accurate at about 0.7x the cost where the march undersamples: + void x4 to x8, wells x16 to x32. + - Above about x16 on the void, the undersampled march is worse than simply + using the expectation (0.095 against 0.025 at x64). That is a band-limiting + result, which the footprint octave weights already exploit. It is not an + exact-integration result. + +## 4. High-octave variance over a span + +- **Span-mean statistics.** Over straight lines of noise length ℓ, the std of + the snoise span mean, against a point std of 0.358, is: + - 0.234 at ℓ = 1; + - 0.170 at ℓ = 2; + - 0.121 at ℓ = 4; + - 0.087 at ℓ = 8; + - 0.061 at ℓ = 16; + - 0.031 at ℓ = 64. + + This is about ℓ^-0.5: the high octaves average out like a random field, not + like a periodic one. +- **Detail octave replaced by its expectation of 0,** on τ = 0.1 spans, measured + as |ΔOD| per span: + - Void: median 0.000 and p90 0.091. Relative to the span's OD (OD > 0.01) the + median is 2.5% and the p90 is 7.6%. The mean detail displacement is a median + 1.0 world (p90 3.6) against the ramp width S = 50. + - Wells: median 0.11 and p90 5.7 optical depths. The relative median is 72%. +- **Why the wells are so bad.** Normalised to the clamp, the density moves + A·fade/B = 2 per unit of noise, and with extinction 0.5 that is 1 optical depth + per world unit per unit of noise. The mean detail displacement of 1.5 world + (p90 3.8) is 15% to 38% of the floor blend B = 10. The wells' optical depth is + set by where the clamp boundary lies, and that is exactly what the expectation + erases. +- So the expectation is adequate for the void's detail octave and is not + adequate for the wells. + +## 5. The clamp and other nonlinearity + +- **Void.** 50.0% of τ = 0.1 spans cross a regime boundary: 0 (d' ≤ Rh), the + wall ramp, or K (d' ≥ Rc). 45.6% of the active length lies in the ramp, where + the density is `K max(0, 1 − 1.5 (1 − (d'/Rc)²)^0.40)`. That is not a + polynomial in n, so exact ∫n does not give ∫� there. Outside the ramp the + density is constant and needs no noise. +- **Wells.** 42.3% of spans cross the clamp. Only 9.8% of the active length is + unclamped, so most of the length where the noise "matters" is length where the + noise only decides whether the density is zero. +- **The decisive check: transmittance error.** This is the sup over the ray of + |T_est − T_true|, with the truth taken on a 0.5- or 1-unit grid. + + | Estimator | Void median / p90 | Wells median / p90 | + |---|---|---| + | Shipped march | 0.020 / 0.038 | 0.033 / 0.155 | + | March at 4x density | 0.006 / 0.009 | 0.030 / 0.049 | + | Density of the *exact* span-mean n (τ = 0.1 spans) | 0.072 / 0.125 | 0.719 / 0.997 | + + The last row is an upper bound on what any exact-mean method can deliver + without also modelling the distribution inside the span. It is the + Heitz-style correction the survey describes. It loses to the march on both + fields. + +## Triangle basis (operator's addition) + +The triangle noise is `triNoise3d` in Aetheria `Assets/Shaders/Volumetric.cginc` +(origin/master f1dee184). +- `tri(x) = |frac(x) − 0.5|`. +- It runs two Nimitz-style iterations. Each iterates `p += tri3(bp·2)`, scales + `bp` by 1.8 and `p` by 1.2, and adds `tri(p.z + tri(p.x + tri(p.y)))/z`. +- It makes 18 tri calls per evaluation. + +As shipped, `density()` uses it as follows: +- `pow(triNoise3d(·), exponent)`, with Noise.Exponent −0.25 multiplied by a + slope `flatness` read from a texture (NOISE_SLOPE is on). +- Two phases, warped by `globalFlow`, which is + `Tri3D = cross(normalize(tri3(P)), normalize(tri3(1.618P))) × 15`. +- The fine octave at ×8 is evaluated at a `pos` whose y the coarse octave has + already displaced. +- Amplitude −36.17. + +Self's reading, tested: + +- **"The warped ray is an exact polyline."** This holds for the warp *inside* + `triNoise3d`. It does not hold for Aetheria's flow: `normalize` and `cross` + make the flow piecewise rational. With the normalize dropped, the cross product + of two piecewise-linear vectors is piecewise quadratic. tri composed with a + piecewise polynomial stays piecewise polynomial of the same degree, with + breakpoints at quadratic roots, so that variant is still closed-form. + Counted along the real flow at the worst shift, the kinks run 15% to 30% above + the straight-ray counts, but the pieces between them are curved. +- **"The clamp roots are linear."** This holds only if the exponent is 1. With + −0.25·flatness, each piece is `(a + bt)^e`. One such piece has a closed-form + integral, but the clamp's root on a sum of two powered phases plus the + smoothstep fade has none. +- **"Whole periods give the exact mean."** This holds for one triangle wave at + whole periods, where the mean is exactly 0.25. It fails for the composed form, + which has no period along a general line; the scales 2, 1.8 and 1.2 and the + nested warp are incommensurate. + - Measured on lines, the span-mean std of `triNoise3d` is 0.029 at ℓ = 1, + 0.010 at ℓ = 8 and 0.0042 at ℓ = 64, against a point std of 0.083. That is + about ℓ^-0.47, the same random-field decay as simplex. + - Its bias against the global mean of 0.1995 is within ±0.0015, so the + expectation is unbiased. It is not exact. +- **The cost decides it.** The exact piecewise-linear walk is verified, matching + a 1e-4 quadrature within 3.4e-8. But the nest has 77.7 linear pieces per noise + unit of straight line, against 3.44 lattice points for simplex. + - One piece costs 1.38 point evaluations with a derivative carried. + - At Aetheria's scale, on the wells rays, the pieces per world unit and the + exact cost relative to the march are: + + | Octave | Pieces per world unit | Exact cost / march | + |---|---|---| + | x1 | 0.20 | 2.8x | + | x2 | 0.38 | 5.5x | + | x4 | 0.76 | 11x | + | x8 (shipped fine) | 1.5 | 22x | + | x64 | 12 | 176x | + + - On the void rays it is 4.1x at x1 and 29x at x8. + - At the same time the march's RMS error on the span mean is already small: + 2.4e-3 at x1 and 1.7e-2 at x8. + +## Per-basis verdict + +| Basis | Exact line integral | Under the shipped warp | Optical depth | Verdict | +|---|---|---|---|---| +| Simplex (CultMath `snoise`) | Closed form, 0.16 snoise per lattice point, 3.44 points per noise unit; validated | Affine spans of 100 to 300 world at τ = 0.1 cell; error floor about 1e-2 | Not delivered: the void's pow profile and the wells' clamp make � nonlinear in n; the exact-mean transmittance loses 3.6x and 22x | **Viable kernel, wrong target.** Pays only if the density were affine in n over the span, or as a control variate for a march (survey §4, Kettunen 2021) | +| Triangle (`triNoise3d`) | Closed form per linear piece; validated | Not piecewise linear under Aetheria's normalized-cross flow or the −0.25 power; made linear by exponent 1 and a non-normalized flow | Same nonlinearity, plus 78 pieces per noise unit | **Loses.** 3x to 22x the march even where its preconditions hold | +| Gabor kernels (survey §1.2, not probed) | Closed form for any affine-transformed kernel (complex erf, at most 16 terms) | The affine warp spans above transfer directly, with each span a whitening transform | Same density-nonlinearity limit | **Candidate smooth basis for large structure**, to be measured only if the density is first made linear in the noise over a span | + +## What would change the verdict + +- **A density that is affine in the noise inside a span.** For example, the + void's ramp replaced by a linear ramp in d', with clamp crossings bracketed by + the interval bound. Exact simplex integration would then deliver optical depth + directly in the 54% of void length that is outside the ramp's clamps. As + measured, that 54% is constant density and needs no noise at all. +- **Exact integration as a control variate,** not a replacement. The exact mean + is cheap and unbiased for ∫n, and the march corrects the nonlinear residual. + That is the Kettunen construction. It was not measured here. +- **Wider skipping.** The operator's first idea, skipping space outside the warp + range, is already what the interval envelope does, and the probe's active + intervals are its output. + - On the void the noise matters over only about 140 world per ray. + - On the wells, opacity ends the ray within a few world units of entering the + unclamped region.

The load-time check (RefuseRemovalOfForeign) is deleted: the durable read refuses everything it refused, and it could not save that read.

It is evaluated once per root per frame (7 flow evaluations with the Jacobian) | Frame build 39 ms (void, 2540 roots) and 57 ms (wells, 16947 roots), or 19 and 27 ns per 1080p pixel amortised | +| Children inherit the parent's affine frame | The cascade has descendants that are exact affine images, so the warp is evaluated only at the roots | One 3x3 product per child, from a table | +| Not allowed | A per-point warp `x + w(x)` inside a span: the warped ray curves, which was the first probe's problem | n/a | + +### Transfer and placement + +| Rule | Status | +|---|---| +| Any function of the kernel centre: the shipped clamp, `pow`, the smoothstep fade, the noise-averaged density `E_n[�(x, n)]` from 16 empirical noise quantiles, through a 1D LUT over d (void) or s (wells) | Exact by construction, at one lookup per kernel | +| Affine transfer of the sum (`a + b Σ K_i`) | Exact | +| Any 1D function of an *affine* coordinate, `∫ f(a + bt) dt = ΔF / b` (pre-integration, Engel 2001) | Exact [derivation, not probed]: height fog `exp(−y/h)` and ramps in y | +| Polynomial or exp of a *quadric* coordinate; an indicator or clamp of a quadric (chord through roots) | Exact [derivation, not probed]: spherical shells and paraboloid bowls as envelopes | +| Product of the sum with a polynomial envelope in t | Exact, polynomial times polynomial [derivation, not probed] | +| Forbidden inside a span: `f(Σ K_i)` for nonlinear f, `max`/`min` of fields, a clamp of a signed sum, or noise displacing an envelope's argument | These are exactly what broke the first probe | + +### Composition: the mass-conserving multiplicative cascade + +- **Roots** sit on a jittered grid: spacing H0 = 30 world on the void and 40 on the + wells, one root per cell. + - Mass is `P(μ)·H0³`, so the mean density equals the shipped noise-averaged + density. + - The ellipsoid is elongated along the flow direction projected on the shell or + fog layer (aspect 1.3 to 2.4), with ±0.6 rad of jitter, and flattened along the + normal (×0.5 void, ×0.4 wells). + - There are two copies per root, at the shipped two-phase shifts with weights w0 + and 1 − w0. Time animation is therefore the shipped crossfade, exact under + summation. +- **Children.** Each node keeps 25% of its mass and gives 75% to Nc = 5 children. + - Child weights are `u²·P(child)/P(parent)`, normalised. The `u²` makes the cascade + intermittent; the P ratio sharpens it toward the envelope. + - A child is scale 0.4, with aspect up to 1.6 and ±0.6 rad of rotation. + - Children sit along the parent's major axis: offset 0.6 along it, 0.21 across. + - All of this comes from a 256-entry table indexed by hash. A descendant bound of + 1.77 times the ellipsoid holds the subtree, so the parent is a BVH node. +- **LOD.** A node is a leaf when its children would be smaller than 0.5 × the pixel + footprint at that depth. It then keeps its full mass. Because the cascade conserves + mass, truncation is a mean-preserving prefilter: the expectation step of the first + probe, exact here instead of approximate. +- **Gather.** + - Roots are binned by their subtree AABB into a hash grid of H0 cells. + - The ray walks the grid with Amanatides–Woo DDA and mailboxing, clipped to the + shipped active windows, so both fields integrate the same span. + - It exits early once Στ ≥ 7, which is valid because every term is nonnegative. + +## "Juice" under these constraints + +| Effect | Mechanism here | Measured or prior art | +|---|---|---| +| Filaments, wisps | Anisotropic children chained along the parent's major axis, which follows the flow | Visible in `void-T-IN-L6.png` as streaks along the flow.

Every method integrates the + same window. + +**Cost.** +- Single-threaded C#, best of three passes over the same 2048 random pixels. +- The host is shared, and absolute timings moved by up to 2x between the smoke run + and the full run; Flow went from 125 to 660 ns. Ratios within one run are the + reliable numbers. +- Flow is 47% of a shipped sample in this run, so a flow-cached march would cost + about 15 µs on the void and 31 µs on the wells. + +| Config (void) | Cost vs march | Roots visited / nodes tested / kernels integrated per pixel | Kernels per level | +|---|---|---|---| +| L1 | 0.12x | 43 / 8 / 8 | 8 | +| L2 | 0.48x | 59 / 25 / 20 | 8, 12 | +| L3 | 1.24x | 74 / 42 / 28 | 8, 12, 8 | +| L4 | 1.81x | 82 / 60 / 35 | 8, 12, 8, 7 | +| L6 (default) | 2.57x | 93 / 86 / 36 | 8, 12, 8, 7, 1, 0 | +| L6, no child placement | 1.79x | 93 / 91 / 39 | same metrics as L6 | +| L6, no LOD | 2.95x | 93 / 103 / 49 | 8, 12, 8, 7, 7, 7 | + +| Config (wells) | Cost vs march | Kernels integrated per pixel | +|---|---|---| +| L1 | 0.04x | 5 | +| L2 | 0.23x | 11 | +| L3 | 0.49x | 16 | +| L4 | 0.77x | 20 | +| L6 | 1.20x | 25 | +| L6, no child placement | 0.62x | 27 | + +**Where the time goes.** +- The integrals are about 36 kernels × 10 ns, or 0.4 µs of a 74 µs pixel. +- The rest is traversal: + - roots visited but missed: 93 visited for 8 hits, because AABBs of elongated + rotated ellipsoids are loose; + - child generation; + - placement lookups. The wells' placement costs a 5-bowl `Sdf`, and dropping + child placement halves the wells cost with identical metrics. + +**Aliasing.** One sample per pixel against four on the default void field: |ΔT| has +an RMS of 0.015 (p90 0.022). At 4 spp the msf is 0.146 against 0.159. So about 92% +of the measured detail is resolved structure, not sparkle. Exact along the ray is +not the same thing as antialiased across the pixel; the LOD rule is the prefilter. + +**Variants, void L6 (msf / power above 1/8).** +- k = 1 default: 0.159 / 12.5%. +- Hard k = 0: 0.145 / 11.0%. +- Gaussian (erf): 0.174 / 14.2%, at 0.89x the polynomial cost here.

The integration-native wells are + layered pancakes with streaked detail. + +## The catches + +1. **The character is a design parameter, and this probe picked one.** + - High anisotropy, axis-chained children and an intermittent `u²` split give + fibres. + - A cloudier look would need rounder children, wider offsets and less + intermittency. That trades away some measured detail and was not swept. + - The detail metrics measure spatial frequency, not taste. The operator has to + look at the images. +2. **The cost is a BVH, not arithmetic.** + - Integration is nearly free. Traversal, child generation and placement dominate. + - Tighter root bounds (OBB tests before AABB bins), cheaper placement and fewer + children are obvious levers, but none was measured. + - On a GPU, variable-length kernel lists per ray diverge. 3DGRT (Moënne-Loccoz et + al. 2024 [memory]) puts the same problem on hardware ray tracing. + - CPU C# ratios do not transfer to the GPU, where snoise is relatively cheaper. +3. **It is all or nothing.** + - This field cannot be marched. At the shipped step, |ΔT| is a median 0.14. + - Shadow rays, light probes and any sampler consumer need the exact traversal too. + The single-scattering pass here cost an exact shadow traversal per view sample: + 257 s for both void SS images together, against 54 s for the whole 512 x 256 + shipped transmittance set. + - Lighting has no closed form. The in-scatter integral is still quadrature. What + the domain makes exact is every optical depth inside it. A per-kernel lighting + cache would amortise shadows, but that is a different shading model (splat-like), + and so a product fork. +4. **Exact along the ray, not across the pixel.** The LOD truncation is the + prefilter. 8% of the measured detail at 1 spp is aliasing. +5. **The wells gain little** because the shipped wells fog is near-opaque. Its look + is the surface silhouette, and that is set at root scale. The domain pays most + where the medium is semi-transparent, as in the void. +6. **Timing noise.** Absolute costs vary up to 2x between runs on the shared host. + The cost ratios above are within one run. + +## What would change the verdict + +- A sweep toward a cloud-like character: round children, Nc = 8, wider offsets, + Gaussian kernels. It should be judged on the single-scattering images against the + same cost. +- Tight root culling: an exact ellipsoid-versus-bin test, or roots stored by + oriented bound. If roots visited fall from 93 to near the 8 hits, the void L3 cost + would fall well under the march. +- A GPU port of one level-limited configuration, to replace the C# ratios with + shader timings.

The + detail reads the unwarped point (`NoiseBoundTests.cs:860`, `Noise.Detail(p, ...)` of the unwarped `p`), yet `Bound` + hands it `ball.w`, which carries `D` (`:875`, `:890`). +- **V2**: V1 with the warp centred. Each phase's coverage ball is centred at + `c + flow(c) shift_k`, with radius `r + |shift_k| rho`, where + `rho = FlowAmplitude L2 FlowFrequency r sqrt 2` bounds how far the flow moves + over the ball. This is the mean-value form of the warp: interval arithmetic + only, no affine noise. +- **V3**: V2 with the centred form of the noise, + `n(c) +- min(L R, |g(c)| R + M R^2 / 2)` from one `snoise_grad`. +- **V4**: V3 with a reduced affine form.

No +variant's pre-pass proved a cell empty where any of the 225 samples per cell +was nonzero (0 enclosure violations). + +What this establishes: + +1. **The oracle cannot be reached by any sound bound.** The oracle mask + samples one depth per ray. A bound must cover the whole slice of the tile, + so the best any exact enclosure could do is about 0.86 of the oracle. That + matches the 0.57-0.85 that conservative visibility methods reach against + exact sets (`docs/research/culling-efficiency-oracle-prior-art.md`). An + oracle target of 0.90 is unreachable by construction. +2. **The warp diagnosis was half right.** At warp `D` most of the gap is the + warp enlarging the radius by its maximum (V0 to V2: 0.194 to 0.347). That + is fixed by evaluating the flow at the ball's centre and enlarging the + radius only by how far the flow can move across the ball. It takes no + affine noise, and it costs one more snoise per probe, for the second phase + ball. The detail octave's spurious warp (V1) is worth little on its own. +3. **Affine noise buys the rest:** the centred form, then the shared depth + symbol. Against the centred interval, affine with one symbol closes about a fifth + of the oracle gap at warp 0 and at warp `D` (efficiency 0.368 to 0.511 and + 0.347 to 0.477). Its combined cost ratio is 1.39x and 1.37x the centred + interval's, and 1.35x and 2.46x the landed interval's. It reaches 0.59 and + 0.56 of the range ceiling. +4. **Three symbols buy about 5% over one** (0.534 against 0.511, 0.502 + against 0.477). One symbol fits a `float3`. Three need a struct or a + `float4` plus a `float`, and the HLSL mirror's harness compares struct + returns but has no struct parameters (`packages/cultmath/docs/design.md:126-135`). +5. **The probe overhead falls** from 0.96 to 0.86 under every centred or + affine bound. Each probe costs a gradient and proves more, so the total + cost still drops by 1.35x to 2.46x. Today's (c) assertion, overhead at + least 0.90 (`NoiseBoundTests.cs:1558`, `:1588`), would reject the cheaper + march. That is question `affine-wells-contract`. + +### The model + +An affine form is a transient value, not a persistent kind.

An affine probe is one `snoise_grad`, counted at +2.0 `snoise` evaluations (an estimate, printed beside the count). Consumers: the gamecult.org ground shader (through the GLSL lowering) and Aetheria's nebula raymarch at its CultMath pin bump. +## Affine forms + +`math.Affine.cs` carries reduced affine forms with one shared symbol: a +`float3(x0, a, e)` is the set `x0 + a eps + e delta` with `eps` and `delta` in +`[-1, 1]` and `e >= 0` (Messine's AF1, as Gamito and Maddock use it for gradient +noise, in one register as an interval is a `float2`). `eps` is shared by every +form over one region (for a screen-tile slice, the depth parameter, `z = z_m + +h eps`), so `af_sub(x, x)` has `a = 0`; `delta` is private to the form, and +every term that cannot be tracked is condensed into `e`. A slice is a +`float4(centre, radius)` with a `float3` axis. No op takes a compound type, a +reference parameter or a swizzle write, so each mirrors into the HLSL common +subset. + +The ops: `af_point`, `af_symbol`, `af_from_iv`, `af_range` (the bridge back to +`iv_*`), `af_add`, `af_sub`, `af_neg`, `af_scale`, `af_add_iv`, `af_mul` (the +product `|a_x a_y|` and the cross-error terms condensed into `e`, so there is +no `af_sqr`), `af_snoise` and `af_fbm`, and the slice pair `af_frustum_axis` and +`af_frustum_ball`. + +Rounding. Every op returns a form whose set at each `eps` contains the float32 +value of its function at every point of its operands' sets at that `eps`. Each +op folds its own float32 rounding into `e` as `S 2^-20`, `S` the sum of the +magnitudes its roundings are relative to (named in the op's comment): at most +`8u S` is needed with `u = 2^-24`, and the factor of two over that is the +allowance for a device whose `+` and `*` are faithful rather than correctly +rounded. `AffineTests.EveryOpEnclosesItsPoints` evaluates the form's set in +double and the function in float32 with no tolerance. + +`af_snoise(centre, axis, radius)` encloses `snoise` over `centre + axis eps + w`, +`|w| <= radius`, from one `snoise_grad`. It returns the narrower of the +Lipschitz form `(n, 0, L R)` and the centred form `(n, g . axis, |g| radius + +M R^2 / 2)` (`R = |axis| + radius`, `L = SNOISE_LIPSCHITZ`, `M = +SNOISE_HESSIAN`), so its total width is never more than the Lipschitz form's. +The centred form is Taylor's theorem, which is why it beats the ball when the +radius is small and the axis carries the variation. `af_fbm` compounds octaves +as `iv_fbm_ball` does. The float32 evaluation allowance is derived in +`af_snoise`'s comment. + +`SNOISE_HESSIAN = 56.050385` is 1.10 times the refined maximum of the spectral +norm of the Hessian of `snoise(float3)`, measured by +`NoiseBoundTests.MeasureHessian` over 1e6 seeded points (central differences of +`snoise_grad`) and refined by ascent from the 1e4 largest: sampled 50.1366, +refined 50.9549, witness (-245.19885, -53.01323, -91.47363). +`HessianConstantPinsSampledCurvature` fails on a 1% move. +`SNOISE2_LIPSCHITZ = 8.117002` is the same for the gradient of `snoise(float2)` +(`MeasureLipschitz2`: sampled 7.2575, refined 7.3791, witness (-67.12454, +-129.53296), `|snoise2|` at most 0.99964), and it backs `iv_snoise_ball(float2, +float)`. Both are empirical with a margin, not proofs; the enclosure tests are +the defence, and a change to the kernels must re-run the measurements. + +The slice. `af_frustum_ball(centreSlope, z0, z1, footprintPerDepth, +warpVariation)` returns the centre `(m_c z_m, z_m)` and a radius `z1 +footprintPerDepth + warpVariation`, with `af_frustum_axis` the axis `(m_c, 1) h`: +every ray point at depth `z` is `centre + axis eps(z) + w`. Its derivation +and the clamp residual are in the comment. The caller rotates, translates and +scales the slice into the noise's frame, and owns the rounding of that. + +The centred warp. A flow-warped sample reads `snoise` at `p + flow(p) shift`. The +caller does not enlarge the ball by the whole displacement `|flow| shift`; it +moves the centre by the flow at the centre, `c + flow(c) shift`, and widens the +radius by the flow's variation across the ball, `r + |shift| rho` with `rho = +FlowAmplitude SNOISE2_LIPSCHITZ FlowFrequency r sqrt 2` (the clamp to the unit +disc is nonexpansive). CultMath owns neither the flow nor the envelope: the warp's +centre and variation are the caller's, and a consumer adds them to the slice's +`warpVariation` or to the form's radius. With two phases that cross-fade, each +phase takes its own centre; one ball serves when the phases' centres coincide +(warp 0). `NoiseBoundTests.CentredWarpStaysEnclosed` checks 2,000 balls and +fails when `rho` is dropped. + +The deep well is the representative Aetheria case: the camera inside a sun's +bowl, looking across. `DeepWellIsTenBandsDeepAndWide` computes the band `G` from +`FogField`'s own floor offset, amplitude and noise range (60) and requires the +depth (633 at the centre against the rim) and the half-depth radius to be at +least `10 G`, every drawn camera sitting inside the well below the rim; a well of +depth 150 fails. The shallow wells stay as the printed shallow-well, band-dominated row (c-band). + +The test field's affine bound takes depth as `af_symbol(z_m, h)`, builds `s` +affine in it with the height interval, the footprint and the slope-depth +product in `e` through `af_add_iv`, takes the noise through `af_frustum_*` and +`af_snoise` per phase and for the detail octave, fades by `af_from_iv` and +`af_mul`, reads the range with `af_range`, and intersects with the centred +interval's bound (both sound). `FogField.Bound` makes no direct `snoise` call. +The cull-map render (`DeepWellCullMap`, explicit) writes a PNG when +`CULTMATH_WRITE_CULLMAP` names a directory: one deep-well camera at warp `D`, +960 x 540 in 8 x 8 tiles, with panels for dense cells per ray under the centred +interval, under the affine bound and under the oracle mask (one logarithmic +scale) and the transmittance. Its run: 4.51, 3.60 and 2.02 cells per ray on +average, 45 the most, mean transmittance 0.278. + ## Rules - Keep type names HLSL-shaped: `float2`, `float3`, `float4`, `float3x3`, and `math`.

These cases have reach |axis| + radius of 1e-6 to 1e-3, where the float32 allowance is most of e and the second order remainder is not; the enclosure above fails a device whose gradient error exceeds the allowance. Centre leg, for every cultmath_af_snoise and cultmath_af_fbm family of this fixture, the earlier ones included: the fixture's own x0 in the result (C#'s value at the centre) must lie in [x0 - e, x0 + e] of the GPU's form, with no tolerance, so a device whose noise differs from C#'s by more than its e fails.", + "cases": [ + "3de98ec0 3e5960a0 3e824700 b64c3554 36674e47 b629f5b3 37601e01 ->

Content seeded from `snoise` at + those points changes; regenerate it when you take this version. + +### Added + +- Interval arithmetic on `float2(lo, hi)`: `math.iv_point`, `iv_add`, `iv_sub`, + `iv_mul`, `iv_neg`, `iv_scale`, `iv_abs`, `iv_min`, `iv_max`, `iv_clamp`, + `iv_saturate`, `iv_lerp`, `iv_sqr`, `iv_sqrt`, `iv_exp`, `iv_smoothstep`, + `iv_snoise_ball` (`float3` and `float2` centres), `iv_fbm_ball` and + `iv_frustum_ball`, with the HLSL mirrors in the new + `Shaders/CultMath.Interval.hlsl`. Each function returns an interval that + contains the pointwise float32 result for every input in the operand + intervals; the enclosure tests check this without a tolerance. +- Reduced affine forms on `float3(x0, a, e)` that share one symbol over a + region: `math.af_point`, `af_symbol`, `af_range`, `af_from_iv`, `af_add`, + `af_add_iv`, `af_sub`, `af_neg`, `af_scale`, `af_mul`, `af_snoise`, `af_fbm`, + `af_frustum_axis` and `af_frustum_ball`, with the HLSL mirrors in the new + `Shaders/CultMath.Affine.hlsl`. +- Noise bound constants `math.SNOISE_LIPSCHITZ`, `SNOISE2_LIPSCHITZ` and + `SNOISE_HESSIAN`: empirical bounds with a margin, re-measured and pinned by + `NoiseBoundTests`. +- `math.asfloat(uint)`, the inverse of `math.asuint`. +- `BoundedLeastSquares.Solve` overload taking `kktRelativeTolerance`, and the + constant `BoundedLeastSquares.DefaultKktRelativeTolerance` (1e-6). The + tolerance must be finite and greater than zero, else the result is + `InvalidInput`. The overload without it passes the default and returns the same + result as before. + +### Fixed + +- The NuGet package `GameCult.Math` now carries `CultMath.Affine.hlsl` under + `contentFiles/any/any/shaders`, as the README says it does. + ## [0.3.0] ### Breaking diff --git a/packages/cultmath/unity/org.gamecult.cultmath/package.json b/packages/cultmath/unity/org.gamecult.cultmath/package.json index 5cd88f8d..368ee715 100644 --- a/packages/cultmath/unity/org.gamecult.cultmath/package.json +++ b/packages/cultmath/unity/org.gamecult.cultmath/package.json @@ -1,7 +1,7 @@ { "name": "org.gamecult.cultmath", "displayName": "CultMath", - "version": "0.3.0", + "version": "0.4.0", "unity": "2021.3", "description": "Precompiled CultMath numeric primitives and matching HLSL semantics for GameCult Unity runtimes.", "license": "MIT AND MPL-2.0", diff --git a/unity/org.gamecult.cultlib/package.json b/unity/org.gamecult.cultlib/package.json index 6545bed1..ca4e940d 100644 --- a/unity/org.gamecult.cultlib/package.json +++ b/unity/org.gamecult.cultlib/package.json @@ -4,7 +4,7 @@ "version": "1.0.60", "unity": "2021.3", "dependencies": { - "org.gamecult.cultmath": "0.3.0" + "org.gamecult.cultmath": "0.4.0" }, "description": "CultCache, CultNet, and CultMesh managed runtime assemblies for Unity.", "license": "MIT", From 476a5fa491683e84f5a0a1895c60ee03638f7150 Mon Sep 17 00:00:00 2001 From: Meta Vens Date: Fri, 9 Oct 2026 22:07:05 +0200 Subject: [PATCH 0324/1146] CultMath: tracked DLL and pdb rebuilt at 0.4.0 on Windows Copied from artifacts/cultmath-unity-build of the release script's first run (netstandard2.1, non-incremental, Source Link off, ContinuousIntegrationBuild).

One runtime ships the solver.** `BoundedLeastSquares` exists only in + `packages/cultmath/src/CultMath/BoundedLeastSquares.cs` (C#, netstandard2.1 and net8.0). The type doc says there is + no HLSL mirror; grep over `packages/*` finds no Rust, TypeScript, Python or Kotlin sibling, and no other CultLib + project calls it. Its consumer outside CultLib is Aetheria's `ThrustAllocator`. +- **B2. The defect reproduces against CultMath at base, outside Aetheria.** `probe1` rebuilds Soul's allocator + matrix (Soul's `ProbeAllocator2`, constants H=100, Wy=1000, W=.3, kappa=10, rho=.1, EMax=2) for hull + `Synthetic(8, 7005)` and the 8th intent of `System.Random(5)`, (-0.8505, 0.6739, 0.5587): 15 rows, 12 columns. + Real `BoundedLeastSquares.Solve` at tolerance 1e-12 from x = 0: `Converged`, 13 iterations, cost 36.0313737, + x7 = 1. Re-solving from that answer: 1 iteration, cost 36.0312608, x7 = 0.9222145, which is also the warm answer. + The same literals (dumped with `"R"` floats, `probe1 dump`) reproduce it at tolerance 1e-9 and 1e-12, and not at + the default 1e-6, where the cold solve stops at iteration 10 inside the tolerance and the re-solve takes 0 + iterations. +- **B2a. The W5 problem as literals** (`probe1 dump`, float `"R"` round trip; m = 15, n = 12, row-major; the + regression fixture for `bls-release-stop`). Nonzero entries of A: + - row 0: a[0,2] = 100f, a[0,8] = -100f, a[0,9] = 100f + - row 1: 13.882518f, 20.86695f, 0, 14.8965845f, 12.38046f, 22.115599f, -13.706654f, 15.85789f, 0, 0, -100f, 100f + - row 2: -187.72859f, 239.31168f, 158.87828f, -270.31165f, 235.38467f, -14.704258f, 121.61232f, 244.81305f, 0, 0, + 0, 0 + - rows 3-6: a[3+k, 8+k] = 0.3f (k = 0..3); rows 7-14: a[7+i, i] = 0.1f (i = 0..7) + - b = {0, 67.385445f, 558.70917f, -3f, -3f, -3f, -3f, 0 x 8}; lo = 0; hi = 1f for columns 0-7, 2f for 8-11. + At base, tolerance 1e-12 from x = 0: `Converged`, 13 iterations, x[7] = 1, cost 36.031373704487095; a re-solve + from that answer: 1 iteration, x[7] = 0.92221445f, cost 36.031260771352414. +- **B3. The stopping rule that fires is the progress rule, after a release** (`BoundedLeastSquares.cs:273-278`). A + traced copy of the solver, bit-equal to the real one on this problem, shows the last two passes: + - iteration 12: full step lands; column 2 sits at its lower bound with gradient -0.00205 (violation 2.05e-3, + tolerance 1.5e-7); the solver releases it and records fMark = f. + - iteration 13: the re-solve moves x2 from 0 to 2.05e-7. The cost falls by about 2.1e-10, and the stall band + `1e-15 * fScale` is 2.11e-10, so `f >= fMark - band` holds and the solver reports `Converged`. Column 7 is then at + its upper bound with gradient +0.00145, ten thousand times the tolerance; releasing it is worth 1.1e-4 of cost. +- **B4. Why the progress rule cannot judge a release.** Near a minimiser, a cost difference resolves only about the + square root of what a gradient comparison resolves: a real step of size dx against gradient g lowers the cost by + about g*dx, while the cost itself is a sum of terms of size fScale. Here g*dx (2e-10) sat exactly at the cost's + rounding band. The gradient comparison is far from its own rounding: for column 7, the bound on the double + gradient's rounding error, `(n+1) * eps * (|A^T b|_7 + sum_k |(A^T A)_7k x_k|)` (Higham's inner-product bound, + gamma_(n+1)), is 9.3e-10, and the violation is 1.56e6 times that. +- **B5. What the progress rule is for** (commit 43035bc8, and the tests at `BoundedLeastSquaresTests.cs:774-942`). + It stops two kinds of pass that can never reach the tolerance: a free-set re-solve whose residual is rounding on a + near-singular free set, and a release whose violation is itself rounding (kktTol at or below the noise, including + kktTol = 0 when the box point nearest the origin is stationary). Deleting it outright breaks both: with a noise + gate on every test and no progress rule, 8 of 66 BLS tests fail (`wide`, `integer-tie`, `collinear`, `cond` spin to + the cap; `NearSingularFreeSetsConfirmOnceAndStop` sees 0 confirmations). Exempting releases from the progress rule + with no noise gate fails one: `StalledPassesConvergeInsteadOfSpinningToTheCap("plain")` seed 141, b = 0, + kktTol = 0, cycles release 3 (violation 1.7e-18) / stationarity miss / block on 3 until the cap. +- **B6. The candidate fix, measured.** In a scratch copy of the package (`suite`, diff `suite/clean.diff`, 44 lines): + (a) a bound column is a release candidate only if its violation exceeds both kktTol and the rounding bound of B4; + (b) the progress rule judges only passes that release nothing; a pass that releases sets fMark to +Inf, so a + release is never measured against a cost recorded before it. Results: + - all 66 tests in `BoundedLeastSquaresTests` pass, including `DefaultSolvesAreBitIdenticalToTheirGoldenBits` and + every stall and noise-floor test; the same holds with the bound's factor at 1, 16 and 256 in place of n+1; + - the W5 problem: cold `Converged` in 14 iterations at the warm answer (x7 = 0.92221, cost 36.03126077); + - 400 synthetic hulls x 60 random intents (24,000 calls, warm and cold) at tolerance 1e-12: every call `Converged`, + max iterations 45, warm and cold agree within 6e-8 on every call (the original: one call off by .078 in the first + 2,400). At the default tolerance warm and cold still differ, by more than .1 in 10,273 of 24,000 calls: that is + the documented resolution of 1e-6 times the gradient scale, pinned by + `AnAllocatorShapedProblemIsStartIndependentAtATightTolerance` (spread >= 0.5), and not this cut's subject. +- **B7. Released columns the factor drops.** With the fix, 266 releases in the suite land on a column that + `SolveFreeSet` marks dependent (p = 0). The next pass is then a stationarity miss with no release, and the + progress rule stops it, as before. No release in the suite or the 24,000 allocator calls produced a step that moves + the released column outward. A Lawson-Hanson style rejection guard (re-bind the column, try the next candidate) + was prototyped and is not needed by any measured case; it is not in the cut. + +### Prior art, and which one the solver follows + +- The solver is a primal active-set method on the normal equations: solve the free set, step to the first bound + crossed, release the most violated bound only after a full step lands. That is the outer/inner loop of + Lawson-Hanson NNLS (1974) generalised to two-sided bounds, which is the shape of Stark-Parker BVLS (1995) and of + scipy's `lsq_linear(method='bvls')`. It differs in factorisation (Cholesky of `A^T A`, not QR of `A`) and in + stopping. +- Lawson-Hanson stop on the dual test only (netlib `NNLS`, label 350: `IF (WMAX .le. ZERO)`), and guard roundoff + per candidate: a column whose new norm is negligible against rounding (`DIFF(UNORM+...)`) or whose new + coefficient is not positive (`ZTEST .gt. ZERO`) is rejected with `W(J)=ZERO` and the next candidate tried. There is + no cost-based stop. +- scipy's BVLS (`scipy/optimize/_lsq/bvls.py`, main) measures KKT exactly as CultMath's status doc states + (`g * on_bound` for bound variables, `|g|` for free ones, max over components) and has two stops: optimality below + `tol` (status 1) and a relative cost change below `tol` (status 2), reported as different statuses. +- CultMath reported its cost stop as `Converged`, which its status doc defines as "the KKT conditions hold". The fix + follows Lawson-Hanson: a release is judged on the gradient against its rounding (the role of their `DIFF` test), + and the cost stop is kept only where no gradient test can decide (a free-set residual at rounding level), which is + where scipy's status 2 also lives. + +### Rejected alternatives + +- Remove the progress rule and stop on the gradient alone: B5, 8 failures. +- Report the cost stop as a new status (scipy's status 2): the W5 answer would still be wrong, just labelled, and a + new enum member is a breaking change for callers that switch on the status. +- Measure progress from the step (the exact model decrease `t(1-t/2)|L^-1 g|^2`) instead of differencing the cost: + exact, but a noise-level gradient still yields a tiny positive decrease, so it needs the same noise threshold, on a + quantity further from the KKT test than the gradient itself. + +## I. Naming the invalid input + +Follow-up `cultlib-gaps:follow_up:bls-invalid-input-field` (from Soul finding +`cut-bls-kkt-tolerance.s1.invalid-input-names-no-field`): every validation failure returns the same `InvalidInput`. + +- **I1.** Validation today is three sites in `Solve`: tolerance (`:147-148`), bounds (`:149-151`), and finiteness of + A and b folded into the `A^T b` build (`:153-161`), which cannot tell A from b. +- **I2.** Precedent: LAPACK reports a bad argument as `INFO = -i`, naming the argument and never its value. .NET + throws `ArgumentException` with a parameter name, which the solver's no-throw, zero-allocation contract rules out. +- Recommended shape (question `bls-input-error-shape`, option `validate-helper`): a public + `BoundedLeastSquares.Validate(m, n, a, b, lo, hi, kktRelativeTolerance)` returning a new enum + `BoundedLeastSquaresInput { Valid, InvalidTolerance, InvalidBounds, NonFiniteMatrix, NonFiniteTarget }`, the first + failure in that order. `Solve` calls it and returns `InvalidInput` for anything but `Valid`, so validation has + one owner and the folded finiteness check in the `A^T b` loop is deleted. Additive: `InvalidInput` and every + existing result stay. + +## R. Release 0.4.1 + +- **R1.** `org.gamecult.cultmath` is at 0.4.0 (`package.json:4`, `CultMath.csproj:13`, tag + `cultmath-unity-v0.4.0`). `scripts/check-changelog-semver.mjs:97-101`: in 0.y.z a minor bump is the breaking lane; + additions and fixes take the patch lane (0.2.4 added `erf` as a patch). +- **R2.** Cut 1 changes results only where the old solver stopped after a release whose violation was above both the + caller's tolerance and the gradient's rounding, that is, where it reported `Converged` in breach of its status doc. + The default path's golden bits are unchanged (B6). The 0.4.0 precedent (ruling `cultmath-0-4-0-breaking-r2`) + declared the snoise tie fix Breaking because two valid functions gave different values; here the old value broke + the documented contract. Question `bls-fix-release-lane` asks which lane; the recommendation is `fixed-patch` + (0.4.1, `### Fixed`). +- The release procedure is the 0.4.0 cut's (`cultlib-gaps:cut_spec:cut-cultmath-release.r1`): Windows-only DLL rebuild + on Starfire, tests on Yggdrasil, public-surface diff, Unity import smoke, Soul before the tag. + +## Q. Rotation algebra + +Ruling `aetheria-release:ruling:solver-in-gamecult-animation`: CultMath gains quaternion algebra, swing-twist and +joint clamps; the aim-chain solve lives in a new package GameCult.Animation. The interface the consumer needs is the +Aetheria map's section "The rig's interface to GameCult.Animation and CultMath" (Aetheria `origin/master` +`30d02719`, `docs/aetheria-release-map.md:7559-7601`). + +### Body facts + +- **Q1. What exists.** `quaternion` (`src/CultMath/quaternion.cs`, 95 lines): public float fields x, y, z, w; + `identity`; `LookRotation(float3 forward, float3 up)`; implicit conversions to and from `float4`; scalar `==`. + `math.normalize(quaternion)` (`math.cs:225-235`) returns identity below length 1e-20. No mul, rotate, conjugate, + inverse, axis-angle, slerp, swing-twist or clamp exists. `math` is a partial class (`math.cs`, + `math.Interval.cs`, `math.Affine.cs`, `math.Phacelle.cs`); `math.rotate(float2, float)` exists (`math.cs:240`). +- **Q2. Serialization.** `GameCult.Caching.MessagePack` serialises `quaternion` as the float array [x, y, z, w] + (`CultMathResolver.cs:170-171`) and as an xyzw object in JSON (`CultMathJson.cs:468`). No other runtime + (`cultcache-rs`, `-ts`, `-py`) has a quaternion type. The cut adds static functions only: no field, layout or + formatter changes, so no wire change and no cross-runtime fixture. +- **Q3. Runtimes.** The algebra is C#-only, like `LookRotation`: shaders carry rotations as `float4` (the type's doc), + the mirror tests map shader functions to C# and never the reverse (`HlslSourceCompatibilityTests.cs:114-117`), and + the native core (`native/cultmath-core`) is a Voronoi tone helper. The Unity bridge already converts `quaternion` + (`UnityConversions.cs:16,23`); it needs no change. +- **Q4. An overload trap, probed.** `quaternion` converts implicitly from `float4`, and CultMath has no + `mul(float4, float4)`. `probe3` declares `mul(quaternion, quaternion)` beside scalar and matrix `mul` overloads and + calls it with two `float4`: it compiles and returns the quaternion product. HLSL's `mul(vector, vector)` is the + inner product, and Unity.Mathematics 1.3.3 (the copy in Aetheria's PackageCache) defines `mul(float4 a, float4 b)` + as such (`matrix.gen.cs:129`), so the same call there is a dot product. The cut therefore adds HLSL's vector + `mul(float2|3|4, float2|3|4)` (dot) beside the quaternion `mul`, so a `float4` pair keeps its shader meaning. +- **Q5. Unity.Mathematics as reference, not template.** Its signatures for `mul`, `rotate`, `conjugate`, `inverse`, + `AxisAngle` and `slerp` (`quaternion.cs:99,493,502,630,651,678`) are the consumer's stated convention ("`mul(a, b)` + applies `b` first"). CultMath's design rule is to state semantics in code and not copy Unity.Mathematics + (`docs/design.md:465-469`), so the formulas are written from the definitions below. + +### Semantics the cut lands + +Quaternions are Hamilton, stored xyzw, unit for rotation; angles are radians, right-handed about the axis. + +- `math.mul(quaternion a, quaternion b)`: the Hamilton product; `rotate(mul(a, b), v) == rotate(a, rotate(b, v))`. +- `math.rotate(quaternion q, float3 v)`: `t = 2 cross(q.xyz, v); v + q.w t + cross(q.xyz, t)`; q assumed unit. +- `math.conjugate(q)`: (-x, -y, -z, w). `math.inverse(q)`: `conjugate(q) / dot(q, q)`, no guard (zero in, non-finite + out, as HLSL division). +- `quaternion.AxisAngle(float3 unitAxis, float radians)`: (axis sin(r/2), cos(r/2)); the axis is not normalised. +- `math.slerp(a, b, t)`: shortest arc (negate b when `dot(a, b) < 0`); normalised lerp when the quaternions are + nearly parallel; t is not clamped. +- `math.swing_twist(q, unitTwistAxis, out swing, out twist)`: twist is q's projection onto the axis, normalised + (identity when that projection vanishes, a half-turn swing); `swing = mul(q, conjugate(twist))`, so + `q == mul(swing, twist)` (twist applied first). +- `math.clamp_twist(twist, unitAxis, min, max)`: angle `2 atan2(dot(twist.xyz, axis), twist.w)` wrapped to (-pi, pi]; + inside [min, max] the input is returned unchanged, otherwise `AxisAngle(axis, clamp(angle, min, max))`. +- `math.clamp_hinge(q, unitAxis, min, max)`: `clamp_twist` of q's twist about the axis; the swing is discarded. +- `math.clamp_cone(swing, unitAxis, maxAngle)`: the angle between `rotate(swing, axis)` and `axis`; inside the cone + the input is returned unchanged, otherwise the rotation by `maxAngle` about `normalize(cross(axis, + rotate(swing, axis)))` (at a half turn, where that cross product vanishes, about the swing's own axis). +- Preconditions (`min <= max`, unit axes) are documented, not checked, as everywhere in `math`. + +### What GameCult.Animation will need from this cut (not mapped here) + +- From cut 4: `mul`, `rotate`, `AxisAngle` for `AimChain.Pose` and `EffectorDirection`; `conjugate` or `inverse` for + frame changes; `swing_twist` and the clamps if its joints ever carry cone or twist limits (the presenter's per-axis + boxes do not). +- From cut 1: start-independent `BoundedLeastSquares` at a tight tolerance. `AimChainSolver.Solve` is warm-started + from `current`; without cut 1 its answer would depend on the previous frame exactly as the allocator's did. +- A CultMath release that carries cut 4, which `org.gamecult.animation`'s `package.json` pins.

Three Idunn guards cited at :10-14. [local] A tolerated extra trailing slot or a null-collapsed arm would not re-encode to the stored bytes; whether those guards would run on such records was not tested. +- No evolution/compatibility doc: `ls docs | grep persist|evol|compat|schema|version` returns only persisted-record-encoding.md. docs/document-variants-cut.md:327-333 covers union-slot reuse at registration ("late union-slot reuse passes registration"; "interface unions are never minted") [local, grep lines only]. +- Reference union handling: src/GameCult.Caching/CultInspectorModel.cs:768-774 classifies an abstract/interface type by its [UnionAttribute]s ordered by key and refuses a type with none ("declares no [Union] subtypes", :772); also :120. This is the inspector's shape classifier; decode is MessagePack-CSharp's. No other use of UnionAttribute in src/GameCult.Caching. [local] +- Trailing-slot tolerance: packages/cultcache-ts/test/cult-cache.test.ts:1176-1195, "CultCache interop reader accepts missing compatible trailing slots and rejects mismatched slots": a legacy-payload store with fewer slots reads with `tags: []`; a mismatched-type payload rejects with /Expected string/u. Missing trailing slots are tested; extra trailing slots are not. [local] +- TS decode: packages/cultcache-ts/src/cult-cache.ts:679-692 wraps a formatter as `schema.parse(decode(payload))`, so TS strictness is whatever the zod schema says; no TS union codec (follow-up text).

Rust enum arms persist as serde external tags (follow-up text). [local] +- Consumers persisting unions: Aetheria (F:\Projects\Aetheria) has `[Union]` abstract classes in Assets/Scripts/ServerShared: Provenance.cs:96-98 (keys 0-2), ItemInstance.cs:18-21 (keys 0-3) and :29-31, Environment.cs:73. The assembly registers CultCache documents (AssemblyInfo.cs:3-4; Galaxy.cs, ItemData.cs, AetheriaStores.cs reference CultCache); ItemInstance is held in entity item lists (Entity.cs:2003). An older build reading a store with a newer arm key would take the C# null-arm path, if these types sit inside persisted CultCache documents; that persistence path was not traced. Aetheria-legacy has more unions (Behaviors.cs:29-38, Item.cs:43-63, Contract.cs:10-11); commented-out keys 8, 9 at Behaviors.cs:37-38 show arms retired in place.

Same-runtime older-build-reads-newer-store: unverified. +- The question document records the C# measurement: extra trailing slot skipped and equal; missing trailing slot leaves member default; unknown arm null, for a Node in a list and for an Outcome; Rust and TS union decoders with explicit keys refuse by construction; Rust extra-slot behaviour unmeasured [local, view]. + +## 4. Operator's stated value, and how each option relates (inferred) +Verbatim, operator-rapport.md:50: "nobody should have to carry bytes they don't understand ... CultCache's whole promise is that a cache's contents are self-identifying via the upfront catalog." Context: pushing back on storing retired slots as metadata (:49). [local] +- Preserve-unknown (protobuf, Unity): the older reader carries bytes the catalog does not describe. Opposite to the stated value. +- Drop silently (Avro extra fields, MessagePack slot skipping, Thrift skip): nobody carries the bytes, but the loss is silent and a re-encode no longer equals the stored bytes (persisted-record-encoding.md:4-6). +- Null the arm (current C# union behaviour): the unknown arm becomes a value the catalog does not describe either; the record decodes as if valid. +- Refuse (Avro no-branch, serde default, Rust/TS explicit-key decoders, store-header refusal): the reader declares it cannot understand the bytes; consistent with self-identifying content because undescribed content is not accepted. +- Tolerate trailing slots but refuse unknown arms (fork option 1): the catalog-described slot list governs required members; slots beyond it are skipped, which is the drop-silently pattern for slots and the refuse pattern for arms.

Arms are +ruled and slots are not, so the slot rule is its own cut rather than a blocked step inside every runtime's cut. + +## Model page (step 0b) + +| Kind | What names it | Over time | Who decides | +|---|---|---|---| +| Union arm | An integer key, `[Union(k, typeof(Arm))]` on the abstract base (C#), assigned by the union's author. The wire carries `[k, armSlots]`; the arm's type name never travels. `nil` is a null reference, not an arm. | **Added:** a key never used before. **Retired:** the attribute is removed or commented out and the key is never reused (Aetheria `Behaviors.cs:160,173`; Aetheria-legacy `Behaviors.cs:37-38`). **Renamed type:** free, the key is the identity. **Unknown to a reader** (a newer writer's arm, or a retired arm in an old store): refused, naming the union and the key (ruling). | The union's author assigns keys. The C# reference defines the shape; every runtime keeps parity with it (doctrine, `runtime-parity-scope.md`). | +| Arm subtype on write | The value's runtime type must be one the union names. | A subtype the union does not name is today written as `nil` (U4). After cut 1 it is refused. | The union's author, by naming the arm. | +| Arm slots, record slots | `[Key(n)]` integers, base-class keys included (an arm is a flat array). Gaps are written `nil`. | **Added:** appended at the next free key. **Retired:** kept as a gap, never reused (Aetheria `ItemInstance.cs:35`, `EntitySerializer.cs` key 5). **Missing in an older store:** the reader's default (C# field initializer; Rust and Python need a declared default). **Extra past the reader's last key:** skipped silently today in every runtime (U3, U6); the question decides. | The type's author. The slot rule is CultCache's (`src/GameCult.Caching/Contracts/cultcache-schema-compatibility.md`). | +| Serde-enum member (Rust) | serde's external tag: the variant **name** (`{"Name": fields}`, a unit variant the bare string). | Persisted already by Rust consumers (section C). They keep their bytes: the union derive is opt-in and serde enums are untouched. | The Rust consumer. Not a cross-runtime shape. | + +## U. Mechanism facts (C# reference, Rust, TS) + +- **U1. The miss branch is `Skip` then `null`, in both union formatters MessagePack-CSharp 3.1.7 can hand out.** + `DynamicUnionResolver.BuildDeserialize` (decompiled from `MessagePack.dll` 3.1.7 net9.0 with ilspycmd): after + `ReadArrayHeader() == 2` (else `InvalidOperationException "Invalid Union data was detected"`) and `ReadInt32`, a + non-zero-start key set is mapped through `keyToJumpMap.TryGetValue`, a miss sets the index to `-1`, the `switch` + default calls `reader.Skip()`, and the result local stays `null`. The source generator's `UnionTemplate` + (`MessagePackAnalyzer` 3.1.7, `MessagePack.SourceGenerator.dll`) emits the same: `default: reader.Skip(); break;` + with `result = null`. Its serializer writes `nil` when `typeToKeyAndJumpMap` has no entry for `value.GetType()`. +- **U2. The C# reference decodes an unknown arm to null and does not re-encode to its bytes.** Probe `cs` + (payload built by hand with `MessagePackWriter`, decoded with `CultDocumentMessagePackSerialization.OptionsFor`): + unknown key 9 in a union field gives `Root=NULL`, in a list `Items=[TextNode,NULL]`; re-encode equal: False in + both. The formatter the reference composite hands out for the union is `MessagePack.Formatters.NodeFormatter1` + (DynamicUnionResolver's emitted type; the probe assembly carries no generated resolver). +- **U3. Missing and extra trailing slots, C# payload level.** Same probe: a payload one slot short decodes with + the field initializer (`Added=42`); a payload one slot long decodes with the extra slot skipped. Neither + re-encodes to its bytes. +- **U4. The reference writes an unnamed subtype as nil.** Same probe: `Root = new RogueNode()` (a subclass the + union does not list) serializes to `94 a2 64 32 c0 90 2a`: the root slot is `nil`, and it reads back `Root=NULL`. + Silent loss on the write side, the mirror of U2. +- **U5. Refusal can live at the CultCache layer; no MessagePack-CSharp fork.** Same probe, `strict` options: a + resolver placed ahead of `StandardResolver` returns, for any abstract or interface type with `[Union]`s, a + formatter that peeks (`CreatePeekReader`) the `[key, ...]` header, throws + `MessagePackSerializationException("union Node has no arm 9")` for a key the union does not list, refuses to + serialize an unnamed subtype, and otherwise delegates to the formatter `StandardResolver` would have handed out. + Baseline round-trips byte-identical; both unknown-arm cases and U4 are refused; slot behaviour is unchanged. + Every C# decode path reaches the composite through `CultDocumentMessagePackSerialization.OptionsFor` + (`CultCacheMessagePack.CreateCodec`, `DirectoryMessagePackBackingStore.cs:345`, `CultMesh.cs:2779,3493,3499`, + `CultMeshPrimitives.cs:1158,1230,2357`), so one resolver covers the cache, the directory store and CultMesh. + Consumer resolvers named by `[CultCacheFormatterResolver]` sit ahead of `CultDocumentResolver` today + (`CultDocumentMessagePackSerialization.cs:58-62`); the guard goes first and delegates to the rest of the + composite, so a consumer formatter still encodes the arm while the key check still runs. +- **U6. A top-level extra slot is dropped on write-back.** Probe `cs2`: a C#-written store, mutated as a newer + writer would (catalog member slot 2 added, payload slot 2 `"newer writer data"`), is pulled, the record edited + and flushed. The read succeeds, and the written payload is `['n1', 'edited by the older build']`: the newer + writer's slot is gone. (The schema id was left unchanged, so the migration report said `Kind=Exact`; with a + changed id the documented drift path reports `IgnoredExtraSlots`, `CultCache.cs:840-924`, but writes back the + same way.) +- **U7. Rust today.** Probe `rs` (`cultcache-rs` at `aaf0d7f6`, payloads built with `rmpv`, decoded with + `rmp_serde::from_slice`): a serde enum's unknown variant is refused (`unknown variant 'Exploded'`); the C# arm + shape `[0, [...]]` is refused (`expected variant identifier`); a non-nil value in a gap slot is skipped; a missing + trailing slot is refused (`missing field 'added'`) unless the field is `#[cultcache(default)]`; an extra trailing + slot is skipped (`cultcache-rs-derive/src/lib.rs`, the `IgnoredAny` loop after the slot loop). The derive + accepts named structs only (`lib.rs:51-67`) and writes an empty member list into the catalog + (`src/lib.rs:2706`). +- **U8. TypeScript today.** No typed codec: with no `formatter` a document encodes as a MessagePack **map** of the + zod-parsed object and decodes raw (`cult-cache.ts:679-692`; `@msgpack/msgpack` `encode({id:'d',version:7})` is + `82 a2 69 64 ...`, a fixmap, where the reference writes an array); positional slots exist only in hand-written + formatters (`test/cult-cache.test.ts:1263-1310`). P13 measured that a hand codec matches whichever encoding its + author chose. +- **U9. Python today.** `define_database_entry_type` (`packages/cultcache-py/src/cultcache_py/documents.py:185-276`) + is a slot codec: gaps written `nil`, extra slots ignored, a missing slot defaulted or refused. No union codec. +- **U10. The written contracts.** `cultcache-schema-compatibility.md:75-91` classifies "persisted slot is missing + locally and can be ignored" as soft-migratable drift, reported as `IgnoredExtraSlots`; + `cultcache-persistence-format.md:215-218` says a store reader "never skips a slot it does not understand" for + record envelope slots, and every runtime refuses `extra-slot-full-payload.msgpack` + (`tests/vectors/document-variants-c0`). `docs/persisted-record-encoding.md` says consumers verify canonicality + by re-encoding and comparing bytes. The two contracts disagree about payload slots; the question below is + about that disagreement. +- **U11. Fixture home.** `tests/vectors//`: committed bytes every runtime's tests read + (`document-variants-c0` by Python `generate.py`, `document-variants-c1` written by C#), consumed by + `tests/GameCult.Caching.Tests/PreCut2StoreFormatTests.cs`, `packages/cultcache-rs/src/lib.rs`, + `packages/cultcache-ts/test/cult-cache.test.ts` and `packages/cultcache-py/tests/test_cultcache.py`. The CultNet + precedent for a reference-written vector is `CULTNET_WRITE_VECTORS=1` (`docs/cultnet-error-contract-cut.md:170`). + +## A. Aetheria (C#, the only consumer persisting `[Union]`s) + +Aetheria consumes the reference through Unity packages pinned by tag (`Packages/manifest.json:55-57`: +`caching-unity-v1.4.0`, `cultlib-unity-v1.0.60`), so a CultLib change reaches it only when it bumps the pin. +Its only consumer resolver is `MathResolver` (`AssemblyInfo.cs:4`), which supplies no union formatter. + +- **A1. Unions inside persisted documents** (Aetheria `aac2cf91`, `Assets/Scripts/ServerShared`): + `BehaviorData` (`Behaviors/Behaviors.cs:147-191`, keys 0-11, 15, 16, 18, 20-24, 28, 31-40; 12 and 26 retired, + 14, 17, 19, 25, 27, 29, 30 commented out) in `List Behaviors` of the item data documents + (`ItemData.cs:346,368`); `WeaponData` (`Behaviors/Weapon.cs:15-18`); `EntityPack` (`EntitySerializer.cs:172-173`) + in `aetheria.savedzone` contents and its own `Children`; `ItemInstance` and `CraftedItemInstance` + (`ItemInstance.cs:18-31`, a union whose arms are also a union) in entity cargo and docking bays + (`EntitySerializer.cs:186-187`); `Provenance` (`Provenance.cs:96-98`) in `aetheria.provenanceledger` + (`Provenance.cs:11-15`, `Lot.Origin`); `SavedActionBarBinding` (`SavedGame.cs:221-223`) in `aetheria.savedgame`; + the input layout rows and keys (`InputLayout.cs:29-50`) in `aetheria.inputlayout`. `Brush` + (`Environment.cs:73`) was not traced to a persisted document. +- **A2. `GameData/Aetheria.cc` carries no unknown arm.** Walker `py/store_unions.py` over the git-tracked game + database (12.7 MB, `cultcache.store.v1`, 238 records, 13 catalog entries): `Behaviors` arm keys + {0:3, 1:2, 2:10, 3:5, 4:2, 5:2, 6:3, 8:7, 9:23, 11:2, 16:4, 23:7, 24:5, 31:1, 32:1, 34:1, 35:2, 37:4, 38:10, 39:2, + 40:1}; none retired or commented out; no `nil` element. +- **A3. The run save carries no unknown arm, and does carry missing trailing slots.** Walker `py/run_unions.py` + over `GameData/run.cc` (2026-09-30): `EntityPack` arms 0 and 1 (3 each), `ItemInstance` arm 2 (12), + `Provenance` arm 0 (64), `SavedActionBarBinding` 9 `nil` (empty bar slots). The `EntityPack` arms carry 21 slots + (orbital) and 20 (ship) against today's 22: the `Boss` slot (key 21, added 2026-10-07 in `db4617d8`) is missing, + so today's Aetheria reads this save only because a missing trailing slot defaults. `py/gaps.py`: no non-nil + retired slot (ItemInstance 2, 9, 10; EntityPack 5). `GameData/stale-2026-09-22/run.cc` is the same shape; + `player.cc` holds only `aetheria.playersettings`. `py/slots.py`: every top-level record matches its own store's + catalog exactly. +- **A4. What changes for Aetheria.** After it adopts a CultLib with cut 1, its current stores load unchanged + (A2, A3). A store written later by a build that has added an arm is refused by a build that lacks it, naming the + union and key, where today the arm silently becomes `null` (a gear item quietly loses a behaviour, a lot loses + its provenance) and the next save writes the loss back. Builds already pinned to 1.0.60 keep the null path; a + shipped binary cannot change. Aetheria-legacy does not use CultCache and has no store. +- **A5. Other C# stores.** `%LOCALAPPDATA%Low/GameCult/Aetheria/aetheria-unity.cc` (2026-08-08, 1.2 KB) is a + `cultcache.store.v2.directory-indexed` header from an older layout, not a union carrier. + +## C. Rust, TypeScript and other consumers + +Eyes audit for this pass (session `self-2026-10-10c-eureka`), `git grep` at each repo's `origin/HEAD`, Rust reach +by a lexical script (it can over-count; it does not under-count named fields). Aetheria and CultLib's tests excluded. + +- **C1. Rust: no `DatabaseEntry` record crosses runtimes as a union, and none uses the reference arm shape.** + Records that reach serde enums, each keeping its bytes because the derive is opt-in: + Huginn `epiphany.pipeline.resolution.v2` (`ResolutionOutcome`, external tag, `eureka-pipeline/src/lib.rs:746`, + live on Yggdrasil); Idunn `idunn.deployment_transaction` and `idunn.admitted_generation` (v4 and legacy forms; + internally tagged `#[serde(tag = ..., deny_unknown_fields)]` enums in `control_plane.rs`, `deployment_plan.rs`, + and two `#[serde(untagged)]` enums kept so older transactions decode, `drivers.rs:259,387`; live at + `/var/lib/gamecult/idunn/control.cc`); CodexConnector `gamecult.codex.replay_record.v1` (`CodexReplayState`, + `lib.rs:1017`); Epiphany's Atlas, model-request, persona and receipt records (internal, adjacent, external and + untagged representations; `.cc` files under `F:\Projects\.epiphany-runtime\` and on Yggdrasil). Unit-only serde + enums (a bare string) are widespread in Idunn, Huginn (`Faculty`, the pipeline's unit enums), CodexConnector and + Epiphany. No enum reaches any record in Odin, Muninn, Ghostlight, Huginn `mind-body`, or cultnet-rs and + cultmesh-rs production records. None of these is read by another runtime as a union today, so none is affected + by the arm refusal; the derive changes nothing for them. +- **C2. TypeScript: no consumer encodes a tagged union.** The only hand formatters are StreamPixels + `apps/service/src/realtime/overlay-state-documents.ts:190,232,277` (positional arrays, no union). Bifrost, + Heimdall, Hermodr, Odin scripts, Stonks, Vili, VoidBot (vendored `cultcache-ts`) and weksa have none. +- **C3. C# outside Aetheria: StreamPixels' overlay declares unions; its tracked store holds none of them.** + `apps/overlay-unity/Assets/Scripts/Assembly-CSharp/` (`8d40541`): `ActivationCondition` (10 arms), + `BattleEffect` (2), `StatusEffect` (4), `ItemInstance` (3), `EquippableItemInstance` (2), reachable from + `streampixels.status`, `streampixels.action_item`, `streampixels.skill` and gear documents. Walker + `py/sp_catalog.py` over `apps/overlay-unity/Data/catalog.cc` (`cultcache.store.v1`, 20 records): only + `outfit`, `skin_color`, `hair_style`, `emote` and `hair_color` records, and no `[int, array]` pair at any depth. + Its only consumer resolver is `MathResolver` (`Catalog/CatalogAssembly.cs:6`). CultLib's own + `GameCult.Networking` `Message` union (`Messages.cs:10`) is a CultNet wire message, decoded with + `MessageSerialization.Options` (`MessageSerialization.cs:7`, `DefaultOptions`), outside `OptionsFor`: the arm + guard does not reach it (follow-up). +- **C4. Python and Kotlin: no union-shaped record.** repixelizer uses `define_database_entry_type` with flat + slots; `cultmesh-kotlin` documents are `data class`es with no sealed type. + +So the stores the arm refusal can affect today are Aetheria's (A2-A4, none carrying an unknown arm) and +StreamPixels' overlay catalog (C3, carrying no arm). Every other runtime's persisted enums are serde shapes that +the opt-in derive leaves alone. + +## Rationale + +- **Why a guard formatter, not a fork or a re-implementation.** U5 shows a guard that only checks the key and the + subtype and delegates the encoding is enough. It keeps MessagePack-CSharp's union encoding as the one encoder, + costs one small file, and covers every path that already goes through `OptionsFor`. Forking the generated + template or vendoring `DynamicUnionResolver` would put a second encoder in CultLib. +- **Why the Rust derive is opt-in.** Serde enums already persisted by Rust consumers keep their bytes + (`docs/persisted-record-encoding.md`); a changed default would make every such store unreadable or + non-canonical. A new derive with explicit arm keys is how a Rust type says "this crosses runtimes". +- **Why arms use newtype variants over slot structs.** A C# arm is a subclass whose slots include the base class's + keys. A Rust newtype variant over a struct with keyed slots is the same thing, and it needs the slot code the + `DatabaseEntry` derive already has, factored so both derives share one slot generator. +- **Why the slot rule is a separate, asked cut.** The ruling settles arms and asks for extra trailing slots to be + "settled against the same re-encode rule". Two written contracts disagree (U10), and the current behaviour drops + data silently (U6), so the choice is the operator's and it should change every runtime at once. +- **The recommendation on extra slots is refusal.** An extra trailing slot is the slot-level twin of an unknown + arm: data from a newer writer that the reader's types do not describe. The operator ruled refusal for arms + knowing it costs an older reader the newer record; the same reasoning gives refusal for slots, and record + envelope slots are already refused in every runtime (U10). The alternative with precedent is + `variants:ruling:undeclared-read-only` (a record a type can read but does not declare loads read-only): it would + let an older reader see a newer record without overwriting it, but only where a catalog shows the extra slot + (top level), while most evolution here is nested (A3's `Boss` slot sits inside a union arm). +- **Missing trailing slots stay tolerated.** The reader knows a missing slot and its default, so it carries no + bytes it does not understand, and Aetheria's live run save depends on it (A3). A store whose guard compares + re-encoded bytes (Idunn's) refuses such a record by its own stricter rule, which is that guard's purpose.

Where C# skips, and why a resolver sees it.** + `DynamicObjectTypeBuilder.BuildDeserializeInternalDeserializeLoopIntKey` emits the slot loop's `switch` default as + a direct `MessagePackReader.Skip()` call; the source generator's `FormatterTemplate` writes + `default: reader.Skip(); break;`. `MessagePackReader` is a struct, and neither path raises an event or reads an + option, so the skip itself cannot be observed without a fork. Both fetch every member formatter from + `options.Resolver` (the generated code's `formatterResolver = options.Resolver`), and the union formatters fetch arm + formatters the same way (U1). A resolver ahead of the composite is therefore handed every nested object, list + element and union arm, and can read each one's array header before delegating. +- **S2. The mark arrives in C#.** Probe `cs`: a guard resolver returns, for each concrete int-keyed + `[MessagePackObject]` type, a formatter that reads the array count (from `NextCode` for a fixarray, a peek for + array16 and array32), compares it with the highest `[Key]` plus one (base keys included, MessagePack's member + visibility rule), notes a skip into a `[ThreadStatic]` scope the decode's caller opened, and delegates to the + formatter the rest of the composite hands out. An extra slot at depth 0 (record), depth 1 (nested object), depth 2 + (object in an object), in a union arm and in a list element each arrives as one mark naming the type and both + counts; the clean payload gives none. The guard needs `CompositeResolver.Create` around it so formatters are + cached (uncached, it was 40 times slower). +- **S3. C# cost.** Aetheria `GameData/Aetheria.cc` (12.1 MB; 237 of 238 records decodable with Aetheria.Shared's + types; decoded with `OptionsFor` that assembly; best of 9, three rounds): plain 165-209 ms, a second plain composite + (A/A) 174-193 ms, guarded 179-196 ms. That is 3.7-8.9% over the best plain run, inside the A/A spread. Worst case, + synthetic tiny objects (120,000 records, 23.1 MB, about 24 objects each): plain 618-637 ms with A/A within 4%, + guarded 704-705 ms: 11-19%, about 30 ns per decoded object. +- **S4. A live case in Aetheria.** The same probe, run with the AetherDb release binaries (built 2026-09-30) against + today's `Aetheria.cc`, marks 25 records: `WeaponItemData` whose `BehaviorData` arms (`AutoWeaponData`, + `ChargedWeaponData` and others) carry 34 slots where that build declares 21 or 33. The extra slot is + `WeaponData.Tracking` (key 33, Aetheria `8cd71ed6`, 2026-10-07): inside a union arm, inside a list. Today that tool + reads these records and drops `Tracking` from all 25 at its next landing (S5). Refusing nested extra slots would + stop it opening `Aetheria.cc` at all; read-only lets it open the store and refuses writes to those 25. +- **S5. A C# flush re-encodes every held record, not only the edited one.** `PushAll` and an unconditional + `CommitBatch` write `ToPersistedRecord(entry, SerializePayload)` for every entry (`CultCache.cs:3191-3201`, `3355`, + `3384`), under the local descriptor's schema id and catalog entry. So U6's loss reaches every held record with + unread slots at the next flush of anything. Rust (holds payload bytes and decodes on `get`, `lib.rs:2280-2293`), + Python (holds envelopes and decodes at load, `cache.py:257-285`) and TypeScript (holds payload bytes) carry an + untouched record's bytes. In C#, read-only therefore also means persisted from the original record (bytes, schema + id, catalog entry), never from the decoded document. +- **S6. Rust.** Probe `rs`: the derive's slot loop, with the trailing `IgnoredAny` loop counting into a + `thread_local`, marks depth 1, depth 2 and a list element. Depth 0 is the `DatabaseEntry` derive's own trailing + loop (`cultcache-rs-derive/src/lib.rs:258`), the same edit. A plain serde struct nested in a record already refuses + an extra element (`array had incorrect length, expected 2`), so only derived slot types skip.

The added code is one branch per object, never taken on a clean payload. Rust decodes on `get`, so whether + a held record is writable is answered by decoding its held bytes through the same derive, on the write path only. +- **S7. Python and TypeScript.** Probes `py` and `ts`: a slot codec tree passing a context argument (the shape + `union-codec-py` and `union-codec-ts` build) marks all five positions. Python (40,000 records, 11.1 MB, msgpack + unpack included): +14% against an A/A spread of 8%. TypeScript (120,000 decoded records, codec walk only; no + msgpack in the scratch copy): +20% against an A/A spread of 18%. The check is one length comparison per object. +- **S8. Kotlin has no library slot codec.** `CultDocumentCodec.decode` is written per type by the consumer + (`packages/cultmesh-kotlin/src/main/kotlin/org/gamecult/cultmesh/CultMesh.kt:31-36`), and the package's own Eve + decoders skip extras by hand at 8 sites (`repeat((count - N).coerceAtLeast(0)) { reader.skip() }` in + `eve/EveDocuments.kt`). No slot rule, refusal or read-only, can be held by the library there until it owns slot + decoding. That is a follow-up, not a per-runtime rule. +- **S9. CultMesh decode paths** (`CultMesh.cs:2779,3493,3499`, `CultMeshPrimitives.cs:1158,1230,2357`) go through + `OptionsFor`, so through the guard, with no scope open: unchanged.

91c8352ec5211dee78bf9d45dd275cfd19f0eedb Mon Sep 17 00:00:00 2001 From: Meta Vens Date: Sun, 11 Oct 2026 03:49:47 +0200 Subject: [PATCH 0362/1146] cultcache-py: union codec and nested record codec, held to the C# union-parity golden define_union and define_record_codec share the slot logic of define_database_entry_type (one record codec); a field takes a codec, many, or a thunk for recursion. Unknown arm keys are refused naming union and key, never the payload. All commits build.

A CultUnion key parses as the reference's Int32, negatives included; a key outside it is a compile error. Decode classifies the key as the reference does: non-integer, outside Int32, undeclared (named), and a pair of the wrong length is refused before its key is read; no value is echoed beyond the undeclared key the reference names. The SlotRecord trait, implemented by the shared slot generator, bounds an arm payload, so a String or Option arm is a compile error. compile_fail fixtures use keys other than 0; the derive crate's unit tests assert each refusal's message.

Leaves int32, int64, float32, float64 replace number; every codec carries the reference's type name and a slot record derives its catalog members from them. Not built or run at this commit.

So content no formatter reads is not counted (inferred from the + README contract; the CultLib measurement in the question confirms it: an extra trailing slot + of 100000 nested arrays is accepted). +- Write: no depth check in the serializer or writer in the code fetched (MessagePackReader.cs + holds `Depth` at :53-75,133; the writer was not fetched). The CultLib question reports a + 3001-deep payload written and then refused on read. +- Advisory GHSA-7q36-4xx7-xcxf / CVE-2020-5234 (published 2020-01-31): "Untrusted data can lead + to DoS attack due to hash collisions and stack overflow in MessagePack". Affected < 1.9.11 and + >= 2.0.0 < 2.1.90. Mitigation is opting into `UntrustedData`; the advisory text does not state + the depth value. +- Advisory GHSA-cj9g-3mj2-g8vv / CVE-2026-48512 (published 2026-06-25), fixed in 2.5.301 and + 3.1.7: the JSON conversion helpers (`ConvertFromJson`, `TinyJsonReader.ReadNextToken`, the + ext-100 branch of `ConvertToJson`) recursed without consulting `MaximumObjectGraphDepth`; the + advisory says `UntrustedData` "does not fully mitigate" them. This is the class of defect + "a depth limit exists but one recursive path skips it". + +### 2.2 rmp-serde (the Rust runtime's decoder) + +- `Deserializer` has `depth: u16`, initialised to 1024 (decode.rs:181, 213, 294); + `set_max_depth` clamps to `u16::MAX` (:309-310). +- `depth_count!` decrements, returns `DepthLimitExceeded` when the counter reaches 0, runs the + body, increments (decode.rs:51-62). Used for arrays (:566), maps (:583) and ext newtype (:616). + So the usable nesting is 1023 levels (inferred from decrement-then-test-zero). +- `ignored_any` is forwarded to `deserialize_any` (decode.rs:~749-753 `forward_to_deserialize_any!`), + which goes through the same counted paths: skipped containers are counted. +- Write: `Error::DepthLimitExceeded` exists in encode.rs (:37, 49, 64) but a grep finds no site + that constructs it (only definition, `source`, `Display`). The writer has no depth check + (inferred from the three matches). +- Crate version at fetch: 1.3.1 (Cargo.toml). No RUSTSEC advisory about depth was found for + rmp-serde, rmpv or ciborium in a web search (search-engine result, not a database query). + +### 2.3 serde_json + +- `remaining_depth: u8 = 128` (de.rs:34, 63); `check_recursion!` decrements and errors with + `RecursionLimitExceeded` when it reaches 0 (de.rs:1372-1387), used at the `[`/`{` branches of + `deserialize_any` and the typed deserialize methods (de.rs:1434, 1445, 1750, 1801, 1838, 1849, + 1882). `disable_recursion_limit()` exists behind the `unbounded_depth` feature (de.rs:197-216, + 1357-1370). A third-party analysis (search result, not fetched) states the deepest enterable + container is level 127. +- `deserialize_ignored_any` calls `ignore_value()` (de.rs:1910-1916). `ignore_value` (:1102-~1215) + is an explicit loop with a heap `scratch` stack of frames and contains no `check_recursion!` + (the `check_recursion!` lines in the file are all at 1372+). Reading: ignored values in + serde_json are walked iteratively and are not depth-limited (inferred from the code; not + tested). This differs from the question's statement that "serde_json ... count ignored values + the same way". +- Serializer: grep of ser.rs for depth/recurs returns no match. +- Related: serde-json-wasm GHSA-rr69-rxr6-8qwf / RUSTSEC-2024-0012 (2024-02-09), fixed in 1.0.1 + and 0.5.2: "This was fixed by adding a check for recursion depth"; the advisory text gives no value. + rustc_serialize RUSTSEC-2022-0004: parsing had no stack-depth limit and "can cause a stack + overflow, which aborts the process". +- serde_stacker (crates.io description) grows the stack dynamically and is documented as paired + with `disable_recursion_limit()`; its README warns that Drop, Debug and Display on deep values + can still overflow.

The docstring says "Raises `StackError` + when `packed` contains too nested" (_unpacker.pyx:158, 313). Empty containers at depth 1025 are + therefore also refused (inferred from check order). `skip()` runs the same state machine + (fallback.py:599-606 shows `skip` raising `StackError`; the C path is the same unpack function, + inferred). +- Pure-Python fallback: depth is Python's recursion limit; `RecursionError` is converted to + `StackError` (fallback.py:586-606). +- Packer: `DEFAULT_RECURSE_LIMIT = 1024`; `_pack` raises `ValueError("recursion limit exceeded.")` + when `nest_limit < 0` and decrements per container (_packer.pyx:42, 259-262; fallback.py:66, 699-711, 801-804). + +### 2.5 JavaScript + +- @msgpack/msgpack Decoder: iterative, with a heap `StackPool` (Decoder.ts:111-190, loop :640-643); + no depth option appears in the decoder (grep of "depth" returns only stack-pool lines). The + README option table lists `maxDepth` default 100 (README.md:119) and Encoder.ts uses it + (`DEFAULT_MAX_DEPTH = 100`, :9; `doEncode` throws `Too deep objects in depth N` when + `depth > maxDepth`, :173). So the library is asymmetric: encode bounded, decode unbounded in + depth (limited by memory). The CultLib question states TS "parse the whole payload"; consistent. +- msgpackr: grep of unpack.js and pack.js finds no maxDepth option or depth counter. +- msgpack5 (another npm package) GHSA-24ch-f2g6-9hhh (2026-10-08): "The decoder has no + nesting-depth limit for arrays and maps ... exhaust the JavaScript call stack"; fix in 6.1.0 + limits depth to 100 by default, option `maxDepth`, error "Maximum decode depth exceeded". +- msgpack-java: CVE record at vulncheck.com ("through 0.9.12", GitHub issue #1015): + `MessageUnpacker.unpackValue()` "recursively deserializes arrays and maps without nesting + depth limits", causing StackOverflowError.

definition; a short record reads with nil as the reference does; bool arm key pinned DatabaseEntryField validates its key in one place (0..MAX_SLOT_KEY, no bool), so database_entry_field, direct construction and field tuples share the rule. A record shorter than its declared slots no longer refuses a missing slot: the slot is nil and its default applies, as the C# reference reads it. define_union refuses True and False as arm keys, each pinned alone. Every commit builds.

Five Soul passes on `cut-union-codec-ts` each found another payload reader +outside the owner (s3 mesh readers, s4 RUDP put and browser, s5 provider command and the +browser default path). The s5 guard (`payload-decode-owner.test.ts`, one per mesh package) +bans the `@msgpack/msgpack` specifier. Soul's mutant S1 put `decodeWireValue(document.payload)` +at the RUDP put site and the guard passed: a plain decode under another name is not a +specifier. As long as a payload is typed `Uint8Array`, every byte decoder in the program +accepts it, so the rule can only be policed by text. + +## What the type system can enforce (probes) + +Run with TypeScript 6.0.3 (`F:\Projects\Heimdall\node_modules\typescript`) against +`@msgpack/msgpack` 3.1.3 source, `strict`. CultLib pins TypeScript `^5.9`; the rules used +below (structural assignability, intersection widening) are unchanged between them, and +Hands re-confirms on 5.9 with the compile-fail fixture the spec names. Scratch files: +`scratchpad/brand/probe.ts`, `probe2.ts`, `probe3.ts`, `runtime.cjs`, `runtime2.cjs` in the +session scratchpad (not committed). + +| Shape of `payload` | `decode(p)` | `decodeWireValue(p)` | `const u: Uint8Array = p` | Notes | +|---|---|---|---|---| +| `Uint8Array & { __brand: true }` | compiles | compiles | compiles | Intersection brand leaks: still a Uint8Array. | +| `Uint8Array & { [uniqueSymbol]: true }` | compiles | compiles | compiles | Same leak. | +| unique-symbol brand plus a wire decoder typed `bytes & { [brand]?: never }` | compiles (raw msgpack) | error | compiles | The wire decoder refuses the brand, but `const u: Uint8Array = p` (no cast) or any helper taking `Uint8Array` strips it, and then `decodeWireValue(u)` compiles. Laundered with no greppable escape. | +| class with ES `#bytes` field | error | error | error | Nominal. Forgery by object literal is an error. Escapes: `as any`, `as unknown as`, or a named method. Runtime: `decode(wrapper)` throws `RangeError: Offset is outside the bounds of the DataView`; `encode({ payload: wrapper })` silently writes an empty map (`81 a7 payload 80`), so a JS consumer that re-encodes a record corrupts it. Two installed copies of the package are incompatible at type level and at `instanceof`. | +| opaque object type over the same runtime Uint8Array, keyed by a string property: `interface DocumentPayload { readonly "cultcache.documentPayload": true; readonly byteLength: number }` | error | error | error | `ArrayLike`, `new Uint8Array(p)`, a `Uint8Array` helper param, a generic `T extends ArrayLike` and a destructured field all refuse it. Forgery from bytes is an error. Escapes that compile: a named unwrap function, `as any`, `as unknown as Uint8Array`, a helper with an `unknown` parameter that casts inside. Runtime value is unchanged: frames still encode the bytes, JS consumers still work. Two package copies are structurally compatible (a unique-symbol key would make them incompatible). | + +Conclusion: an intersection or unique-symbol brand on `Uint8Array` cannot hold the rule, +because widening to `Uint8Array` is implicit. A class holds it but changes the runtime value +and adds a silent-corruption hazard for JS consumers. The string-keyed opaque object type +holds it at compile time with no runtime change.

A publication binding names a definition, never a bare schema id; the RUDP put handler refuses a schema with no registered definition instead of plain-decoding it. Builds in every package; tests not yet rerun.

Timestamps are unix milliseconds (`i64`), matching `origin_server_ts`.

The doc names only "Heimdall member id" and "Matrix event id". +3. Key text is the parts joined with U+001F; a part that is empty or contains it is refused. Matrix ids can hold most other separators. +4. The tombstone's salted `text` hash has no row in the answer table. It is carried as `Answer.text_hash` (bytes) on the exited record. Which hash function, whose salt, and whether the tombstone is a separate record is undecided; the crate never computes the hash. +5. `Answer.notice_version` and `scope` are optional in the typed record so an answer lacking them can exist and be excluded; the table makes both required. Should such a reply be stored at all, given "is not collected"? +6. A reply under a notice with no recorded scope writes no acceptance in the vector's collector; the doc says the first reply accepts "the notice version then pinned" and does not cover a missing pin. +7. `MemberTerms` is a separate record keyed by `member_id`. The doc puts the fields on the member; the member record lives in Heimdall, not CultLib. +8. Training rule item 2 also requires the acceptance's scope to be `train` and to match the answer's experiment and member; the doc requires only that an acceptance exist for the key with `accepted_at <= received_at`. +9.

The doc puts the fields on the member; the member record lives in Heimdall, not CultLib. -8.

`#[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::()`. ## [0.3.1] diff --git a/packages/cultcache-rs/README.md b/packages/cultcache-rs/README.md index afae7285..2c5c8027 100644 --- a/packages/cultcache-rs/README.md +++ b/packages/cultcache-rs/README.md @@ -174,6 +174,9 @@ without pretending Rust has runtime reflection hiding under the floorboards. - `get_required_envelope::` - `get_all::` - `get_all_with_keys::` +- `get_by_name::` +- `get_by_index::` +- `get_global::` - `soa::` - `put::` - `put_envelope::` diff --git a/packages/cultcache-rs/tests/lookups.rs b/packages/cultcache-rs/tests/lookups.rs index 2c3c4f7c..2467fbc6 100644 --- a/packages/cultcache-rs/tests/lookups.rs +++ b/packages/cultcache-rs/tests/lookups.rs @@ -32,6 +32,20 @@ struct Gadget { category: String, } +/// Sorts after `Item` and has its exact shape: a lookup that ran past the end of its own type would answer from it. +#[derive(Clone, Debug, PartialEq, Eq, DatabaseEntry)] +#[cultcache(type = "zed")] +struct Zed { + #[cultcache(key = 0, name)] + name: String, + #[cultcache(key = 1, index)] + category: String, + #[cultcache(key = 2, index = "sku")] + code: Option, + #[cultcache(key = 3, default)] + value: u32, +} + #[derive(Clone, Debug, PartialEq, Eq, DatabaseEntry)] #[cultcache(type = "settings", global)] struct Settings { @@ -63,6 +77,7 @@ fn cache() -> CultCache { let mut cache = CultCache::new(); cache.register_entry_type::().unwrap(); cache.register_entry_type::().unwrap(); + cache.register_entry_type::().unwrap(); cache.register_entry_type::().unwrap(); cache.register_entry_type::().unwrap(); cache.register_entry_type::().unwrap(); @@ -142,10 +157,12 @@ fn lookups_never_cross_types() { let mut cache = cache(); cache.put("item:a", &item("same", "same", None)).unwrap(); cache.put("gadget:a", &Gadget { name: "same".into(), category: "same".into() }).unwrap(); + cache.put("zed:a", &Zed { name: "same".into(), category: "same".into(), code: None, value: 0 }).unwrap(); assert_eq!(cache.get_by_name::("same").unwrap().unwrap().name, "same"); cache.delete::("item:a").unwrap(); assert_eq!(cache.get_by_name::("same").unwrap(), None); + assert_eq!(cache.get_by_index::("category", "same").unwrap(), None); assert!(cache.get_by_name::("same").unwrap().is_some()); assert!(cache.get_by_index::("category", "same").unwrap().is_some()); } From 9548d51a7108dbfb960d13b8024f7097b15a5876 Mon Sep 17 00:00:00 2001 From: Libby Date: Fri, 6 Nov 2026 20:47:07 +0000 Subject: [PATCH 1089/1146] cultcache-py: msgpack is a hard dependency; drop the optional-import fallbacks pyproject (and cultnet-py) already declare msgpack as required; the code treated it as optional behind a cultcache-py[msgpack] extra that does not exist.

A second client no longer replaces the first; Connects beyond `maxPeers` (default 256) are dropped, and `close()` resolves once every peer's goodbye has left the socket. The shape follows the Rust `CultNetRudpServerHub` and C# `CultNetRudpSocketTransportServer`, and the wire format is unchanged. The optional `peerTimeoutMs` (idle peers ended and told so; default off) exists only in TypeScript. `CultNetRudpSocketTransportConnection` in `server` mode still serves exactly one peer. +- The `cultnet.snapshot_request.v1`, `cultnet.database_subscribe.v1` and `cultnet.snapshot_response_raw.v1` carriers and the selection payload types (`CultNetSelection`, `CultNetRawDocumentHeader`, `CultNetEdge`). `parseCultNetMessage` accepts them (absent members arrive as absent keys; a page carries exactly one of `headers`/`documents`; an empty or blank `schemas`/`keys` entry throws `CultNetSelectionInvalidError` naming its field), and `encodeCultNetMessageForWire` writes the reference's nil-keyed, declaration-ordered map. Judged against bytes the C# reference wrote (`contracts/cultnet/interop/carrier-vectors.cs-written.json`) and the selection vectors C# and Rust wrote. The selection engine (evaluation, cursors, the declaration-dependent door checks) is not ported. + ### Breaking +- `CultNetErrorMessage` carries `routingHint`, `code` and `details` (null when absent), as the reference writes them and `cultnet.error.schema.json` requires; the interface previously dropped them. New `CultNetErrorCode`, `CultNetErrorDetails` and `CultNetShardRoutingHint` types. + - `CultMeshCdnChunkRef` carries `id` (slot 4), the reference's element id. `encodeManifest` writes five-slot chunk references and `packContent` sets the decimal offset as the id, as the reference does; a manifest written before ids reads `""` and is rewritten with the slot. Content vectors regenerated from the reference. - Needs the cultcache-ts release that ships with this change (its manifest range moves with that release): the Idunn runtime authority reader calls `readSingleFileStore`, which 0.14.x does not export. An absent authority file is now a plain `Error` without a code. diff --git a/packages/cultnet-ts/README.md b/packages/cultnet-ts/README.md index c766793b..acbf5a6a 100644 --- a/packages/cultnet-ts/README.md +++ b/packages/cultnet-ts/README.md @@ -65,6 +65,7 @@ Current message families: - `cultnet.snapshot_request.v0` - `cultnet.snapshot_response.v0` - `cultnet.snapshot_response_raw.v0` +- `cultnet.snapshot_request.v1`, `cultnet.database_subscribe.v1`, `cultnet.snapshot_response_raw.v1` (typed-selection carriers;

A second client no longer replaces the first; Connects beyond `maxPeers` (default 256) are dropped, and `close()` resolves once every peer's goodbye has left the socket.

The refusal's record key and reason are clipped so it fits maxPayloadBytes. The allocation test watches transient allocations; catch-path and delete tests assert ids, operation, reply count, onError and handlers.

A refused write is answered with the typed `write_not_authorized` naming the record key (the bytes pinned in `error-vectors.json`), and `onDocumentPutRaw` is never called; pass `writeAuthority: new CultMeshGrantAllWrites()` to keep the old accept-everything behaviour. The authority is asked before the put is sized or decoded and before any handler runs, with the canonical schema id and the peer's address (the schema id is resolved to its canonical form first, which is the timing residual below); one that throws, rejects or answers anything but `granted: true` refuses. A frame the server cannot read is judged as the write it looks like (a put when it does not decode at all), so an ungranted peer gets `write_not_authorized` for it too; a granted peer gets `onError` and a `malformed_document_put` or `malformed_document_delete` refusal.

A second client no longer replaces the first; Connects beyond `maxPeers` (default 256) are dropped, and `close()` resolves once every peer's goodbye has left the socket. The shape follows the Rust `CultNetRudpServerHub` and C# `CultNetRudpSocketTransportServer`, and the wire format is unchanged. The optional `peerTimeoutMs` (idle peers ended and told so; default off) exists only in TypeScript. `CultNetRudpSocketTransportConnection` in `server` mode still serves exactly one peer. diff --git a/packages/cultnet-ts/src/contracts.ts b/packages/cultnet-ts/src/contracts.ts index bc6a7b72..d4bc1b19 100644 --- a/packages/cultnet-ts/src/contracts.ts +++ b/packages/cultnet-ts/src/contracts.ts @@ -196,6 +196,7 @@ export const CULTNET_ERROR_CODES = [ "unowned_schema", "write_not_authorized", "unsupported_schema_version", + "message_invalid", ] as const;

All answers now go the normal reliable path; the session ends when the peer has acknowledged them (a lost one is resent) or after a 2 s grace, and serves nothing after the capped frame meanwhile.
