b37e07a52c cultmath: regenerate CultMath.glsl for the snoise read constants

58a2d50a76 cultmath: one owner of the snoise read's absolute terms (SNOISE_READ_VALUE, SNOISE_READ_GRADIENT)
span_slack and af_snoise each spelled 2^-14 (value) and 2^-12 (gradient) inline, in C# and
HLSL. Both now read the constants beside SNOISE_HESSIAN (math.Affine.cs, CultMath.Affine.hlsl,
Unity copies), so a device-judged widening moves every reader. Bits unchanged. The test
oracles in AffineTests and GlslMirrorTests read the constants; a new test pins af_snoise's
allowance to span_slack's terms. span_slack's comment no longer claims it is the only
allowance. Does not build green yet: CultMath.glsl is not regenerated in this commit.

377c24b8cd cultnet-rs: one decoder per family, duplicate keys refused, value-free receive errors
Raw v1 is decoded by the enum's derive alone (SnapshotResponseRawV1Rows,
the v1 arm and its helpers deleted); the five raw families carry
skip_deserializing so the hand reader is their only decoder. The four hand
readers refuse a duplicated key; refusals carry a schema-shaped
schemaVersion context and never a received value. README describes only
the raw lane. A same-length str-payload credential forgery is pinned.

338a952be0 cultmath: near-origin fold test checks the exact departure to 1e-13
The additive 1e-9 absorbed the whole exact departure at scales 1e-4 and 1e-2 (1e-11 to 1e-9),
so dropping the value allowance's absolute term 2^-14 survived the test. The tolerance is 1e-13.
Test only; builds.

4250dd28d5 cultmath: compile-hlsl.ps1 fails on warnings and on a missing shader without its path; compile-glsl.ps1 passes struct arguments
dxc runs with -WX; a ShaderPath that is not a file throws naming the parameter and entry index,
never the path; the GLSL wrapper builds a struct parameter from its declaration's field zeros.
design.md and README state the struct-argument twin rule, the span twins and the missing shader identity.
No C# change; the compiles run on Starfire after the last commit.

9548e1d0e6 cultmath: HLSL span stage twins over struct arguments; mirror twin rule; span_l1 becomes csum(abs(..))
cultmath_span_stage, cultmath_span_fbm and cultmath_span_ridged with SpanPath, SpanStage and
SpanNoise, statement for statement from math.span_stage (no shader identity). They follow the
includes, not cultmath_ridged_grad: the bounds read the SNOISE_* constants the includes define.
The mirror comparison matches every mirror function to the math function of the same name,
public or private, with struct parameters mapped by name and fields; MirrorOnly is gone.
New tests: identity and realistic-span mirror sweeps, a large-octave-step fold test; the
near-origin fold test gains scales 1e-4 and 1e-2; the integral_clamp_linear tests also read the
committed fixture's cases.

The GLSL, the fixture families and the docs follow: CommittedGlslEqualsLowering and
GoldenFixtureMatchesCSharp are red at this commit. It builds.

b2852304b1 cultmath: flat integral_clamp_linear returns +0 for a zero-length span; HLSL guard, lo-normalise and pin tests behavioural; owned dxc compile script
The b == 0 branch now guards t1 != t0 like the sloped branch (C# and both HLSL
copies), so an infinite bound times a zero length no longer forms NaN.
Edge-grid mirror test and a counting-clamp shadow test replace the text-order
check; the four pin tests assert equality with their measured expression;
tools/compile-hlsl.ps1 is the one dxc compile verdict for the HLSL copies.

Builds. CultMath.glsl and glsl-parity.json are not yet regenerated, so
CommittedGlslEqualsLowering and GoldenFixtureMatchesCSharp are red at this
commit; the next commit regenerates them.

Deletes CultNetDocumentRecord, the DocumentPut and SnapshotResponse variants,
parse_cultnet_message, require_typed, round_trip_typed, the eight replication
functions and the two catalog schemas (parked at tag
parked/cultnet-rs-dynamic-document-lane). decode_cultnet_message_from_slice is
the one decode; raw v1 rows, identity credentials and the signed-record readers
decode through cultcache_rs::decode_payload. Adds tests/decode_door.rs. 0.2.0.

8939af134f cultmath: span tests: long path from rest, near-zero midpoint under a point span and a loose speed bound, fold's float arm read from span_ridged's own field
The fold test's float arm no longer re-spells the octave coordinate (OneOctave): each octave's float value is the difference of span_fbm / span_ridged at o + 1 and o octaves, with a stated bound on what the accumulating float sum loses.
New fixed span at halfLength 6 pins the Gl reach operator (nu / halfLength fails); a near-zero midpoint on a stationary path (halfLength 0, and halfLength 1 under a loose speed bound) pins the halfLength-0 fold rule and S_o's reach term.
Builds: yes (to be confirmed by the Yggdrasil job).
