Adds the policy fields that must be non-zero, the inclusive shard limit at
the decoder for video and audio parity, admission statistics, seeded jitter
bounds, exact seeded loss, and arrival order for datagrams due together.

Pins the block-boundary chunk and last-chunk length refusals in video
recovery, the audio recovery refusals (packets one either side of the block,
another session, wrong length, parity from different blocks), the remaining
audio block identity rules (session, stream, timebase, duration), and the
data-parity alternation inside a block.

cultnet_impair is a deterministic bidirectional UDP proxy for pressure
testing real CultNet RUDP sessions with seeded loss, burst, duplicate,
reorder, jitter and stall schedules. It is ported from the Odin donor
(80adfd3) as an example, not library surface. The decision policy (Profile,
Scheduler, seeded RNG) is split from the sockets into policy.rs, which the
proxy and the tests both compile, so a schedule has one owner. The ten
donor profiles live in tests/impairment/.
tests/impairment_policy.rs keeps the donor's six deterministic policy tests
(the burst test now pins the exact drops rather than a count) and adds
profile loading and rejection. tests/media_fec_loss.rs sends protected video
frames through those schedules with no sockets and asserts the guarantee: a
block recovers exactly when at most m of its records were lost, recovered
chunks equal what was sent, and a burst that the send order spreads under m
per block loses no frame. The recovered-frame ratios are printed, not
asserted; tests/impairment/loss-matrix.txt is that output.

The codec owns the erasure math for both ends: protect_video_frame and
protect_audio_block on the producer, recover_video_block and
recover_audio_block on the consumer. Each block is systematic Reed-Solomon
over GF(2^8) (reed-solomon-erasure 6, default features), named on every
parity record by the scheme id rs-gf256-v1. Any <= m erasures recover
exactly; more report BeyondRepair. Video frames split into ceil(n/16)
near-equal blocks with m = max(2, ceil(k/4)); audio is 4+2. A frame's
records come back in send order, rotating one record from each block so a
burst lands as one loss per block.
Deleted first: gamecult.media_video_parity_shard.v2 and its XOR-stripe
validator, and the reliable "audio" channel (profile entry, send-options
arm, constant, tests). Audio now rides "media" with parity.
Added: gamecult.media_video_parity_shard.v3 (block geometry, scheme id,
shard length), gamecult.media_audio_parity_shard.v1, the AudioParity wire
variant with validation, and the parity record key now names the block.
Every shard is bounded at MEDIA_FEC_MAX_SHARD_PAYLOAD_BYTES (720) so its
wrapped record fits MEDIA_FEC_MAX_WIRE_BYTES (1431), measured with
identifiers of up to 32 bytes.
Tests pin: exhaustive recovery for every shipped (k, m) and 4+2, m+1
refusal, known-answer parity bytes for both paths, the datagram bound on
every record kind, send order, deadline carriage and decoder validation.

Soul verdict: merge. Before Cut 4 relies on sequence density: pin the
publish-on-throw guard in Held and observer removal on unsubscribe.

Every public CultMath value type serializes: MessagePack in the default resolver
chain (byte-identical to Aetheria's and StreamPixels' copies across 653 values
and all 115 float fields of the real Aetheria.cc) and System.Text.Json converters
(STJ-parity number handling, math types as dictionary keys). CultVec2/3 and
CultRect are gone with bytes unchanged. The cultlib Unity package depends on
cultmath; the release gate refuses until CultMath 0.3.0 carries every type.
Three Soul passes.

Named literals now follow AllowReadingFromString and WriteAsString as
System.Text.Json's float does; quoted numbers refuse whitespace;
UnmappedMemberHandling.Disallow and AllowDuplicateProperties=false are honoured
and a repeated property replaces the whole value; dictionary keys read only the
canonical spelling. Components live in stack spans, property names are
pre-encoded, and there is no per-property closure, so a float3 read allocates
nothing (424 bytes before). Tests pin unknown nested values, de-DE and sv-SE
style cultures, and a distinct negative-zero key.

scripts/check-cultmath-types.cs reads the assembly with System.Reflection.Metadata
and reports which named types are not public top-level CultMath types. The old
NUL-delimited string search passed an appended string or a member named like the
type, and failed a real type whose name is tail-shared in the string heap.
Prerelease and range versions now get a clear message instead of a raw
System.Version error.

The held-ancestor path compared the raw empty string, so a blank variant name
and a blank held base name never met the blank rule; NameRead now returns null
for blank on both paths.

Delete the dead removed-ancestor branch and the duplicated name-read in the
variant name rule (resolution already refuses a missing or removed base and a
variant shares its base type). Add tests for the index rule counting a record
the same commit removes, blank names not colliding, and Dispose rethrowing
escaped completions after every observer completed.

One Scalar plus Node description per type now drives reading, writing and the
dictionary-key spelling, replacing the per-value JsonDocument parse. NaN and the
infinities follow JsonNumberHandling (named literals or JsonException), floats
beyond float.MaxValue are refused instead of becoming infinity, out-of-range
components throw JsonException instead of FormatException, property matching
honours PropertyNameCaseInsensitive, and every type works as a dictionary key
spelled as comma-joined components.

The package build now fails when the declared org.gamecult.cultmath version is
ahead of the CultMath package, or when that package's CultMath.dll lacks a type
CultMathResolver formats. It also drops the shipped-plugin guard that could not
fire, since the output root is wiped first.

The is-not pattern binding made every mutant in RefuseVariantNameSharing a

CultMathJson is the JSON twin of CultMathResolver: vectors, quaternion and
Color32 are objects keyed by field name, matrices are arrays of row objects,
rect is {min,max}. Consumers add them with AddCultMathConverters(); CultLib owns
no JSON options. CultCircle and CultSphere serialize and deserialize through
them, with [JsonConstructor] so the struct constructor is used. The Caching
README documents each MessagePack and JSON shape in one table.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Golden bytes now cover double2, double3, int3, int4, bool3, bool4, quaternion,
Color32, Random, float3x3 and CultCellular. A missing Color32 alpha decodes as
255, the constructor default. A test proves a consumer resolver registered for
the assembly wins over CultMathResolver. The redundant nil check is deleted;
ReadArrayHeader already refuses nil.

A database write is published after its cache write returns, so a write whose
observer threw never reaches the database observers on this base. Keep the
probe to the exception reaching the writer and later changes still publishing
and logging; the ordering question belongs to the database cut.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
A direct cache write is not a database change on this base, so the database
observer could not show it. PutAsync is, and the observer after the thrower must
see it.

GameCult.Caching.MessagePack now references CultMath, so the Unity package
declares org.gamecult.cultmath in package.json, references CultMath.dll from the
asmdef, and the package build refuses to ship a second CultMath.dll and checks
the asmdef against the shipped plus external assembly lists.

The cache no longer fans changes out through an R3 Subject. It keeps a
copy-on-write observer array and Publish catches per observer: every observer
receives every change, an exception that escapes (a fail-fast R3 handler) joins
the OnUpdate failures rethrown to the writer after delivery, and the observer
stays subscribed. Dispose completes observers, and a disposed cache completes
new ones at once. Deletes the false "OnNext does not throw" comment.
The composition contract now states the observer policy and that a throwing
name or index getter refuses a change set, loads included.

Resolving a variant serializes its base, and the serializer reads the same
getters; the test measured them together and expected too few.

Resolve now ends in Project, the only place an admission runs a [CultName] or
[CultIndex] getter on a landing record. It runs before land and before any
Sequence is minted, so a throwing getter refuses the admission (loads
included) with nothing written, minted or left in memory. The variant name and
index rules and the indexer read the projection; Apply runs no user code.

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

GameCult.Geometry no longer carries vector or rectangle values. CultCircle and
CultSphere hold float2/float3, the isosurface and surface-nets extractors take
float3 origin, and the per-call conversion to float3 is gone. Their MessagePack
bytes are unchanged (pinned against the pre-collapse encodings), now produced
by CultMathResolver through the default CultCache options.
This is a breaking change to the GameCult.Geometry public API.

The first commit's resolver needs the CultMath project reference and scoped
span parameters to compile; the golden test file also had two literal slips.

CultMathResolver formats float2/3/4, double2/3, int2/3/4, bool2/3/4,
quaternion, Color32, Random, float2x2, float3x3, rect and CultCellular as
component arrays, and sits in the default CultCache resolver chain so no
consumer registers anything. It lives in GameCult.Caching.MessagePack, which
already owns that chain; CultMath core stays dependency-free.
Vector, rect and Aetheria-formatter byte shapes are pinned by golden tests, a
reflection test fails when a public CultMath value type has no formatter, and
decode skips extra elements and refuses nil.

Soul: merge. The drop gate calls the model's one candidate rule; every ref write

Stryker on the escaping showed the pair-skip branch uncovered and the run

The record list draws GroupRecords as foldouts (fold state keyed by listed
type and node id), each with Create through CreateInGroup; an ungrouped type
lists RecordCandidates flat under the model's notice. Add, Create and
Duplicate reveal the new record's path. Rows start the record drag.

A record row dragged onto a CultRecordRef value sets it when the ref's picker
would offer that record (IsRecordCandidate), refusing in a disabled scope, a
foreign model, or the key already held. The ref popup's None/Missing label
now comes from RecordRefLabel.

Uri.EscapeDataString maps every unpaired surrogate to %EF%BF%BD, so distinct

Ids that differ only by %2F versus /, keys that differ only by case, and

Closed after three Soul passes: the double iterate and progress stop hold over
~9000 cases against exact enumeration, zero allocation, deterministic; the stall
rule and fScale are now pinned (all six survivors killed). Ships in the next

Stryker survivors on the grouping diff: the no-declaration path, the
null-string identity, the inherited [CultGlobal] check and the id separator.
GroupLevel takes text and tie as optional arguments so the scalar kinds

Batches of small boxed problems whose passes end with the KKT test failing and
the cost unmoved (dependent free columns, releases the factor drops, weak-direction

scale in Objective, which no test reached before.

Seven values change: four snoise(float3) in HlslSemanticsTests and three snoise(float2)

[CultInspectorGroupBy(nameof(A), nameof(B))] on a document class names the
members its record list groups by, outermost first. CultInspectorModel owns
the rest: GroupingOf validates the declaration (a refused one gives a flat

identity with occupied values only, CreateInGroup builds the record a node
holds, RecordRefLabel owns None and Missing <key>. A variant groups by its
resolved Document.
