Native #1508 completion — 2026-10-11

Exact clean accepted parent23321ac563f7ec5335d755239534d0a17da303d2 -> nativeff2934dd89f806e846babb04626ffa645da5a4b5, one commit/five owned paths. Canonical immutable native receipt6106934096; full modes/blobs/results at /Users/user/.barocss-ai/v3/evidence-engine-uv-texture-material-gpu/immutable-handoff.json. Root plus three scoped helpers used disjoint ownership; native handoff delivered ONCE to sole Integration. Serial adoption is pending its actual receipt.

Actual12 admissions/106 refusals/getters0/24 exact raw reflections/148 runtime exports(parent145+3)/four new types/12 cold rows.

Complete original source is authority; retained resource originals were copied byte-exact without replaying providers. Exact old1184 decode text, independent sampleIR/materialIR/layout/text expectations and old public declarations/authored sample names/provider leaves passed.

Native source/IR/trusted GLSL text only. ValidIR2MiB/text64KiB/lowered128KiB defensive overflow remains unforced. No resource join/evaluator/texture-unit allocation/upload/link/pixels/nativeUV/frame/lifetime/consumer/currentRoot/publication claim. Owner#1507 source-only reference response 6106859687 remains separate; no cache/backend/library migration.

Immediate useful owned continuation is existing #1184 authored sampler/resource CPU join preparation, GPU-Engine-UV-Texture-Bindings-Preparation. Existing fixed catalog and numeric binders cannot bind the new profile by casts; actual #1508 adoption and exact remaining DTO/error/copy contracts gate implementation. Pending unrelated Viewer/Physics/Shell/graphics do not block preparation. No duplicate Issue or repeated immutable handoff is created. Earlier pending/READY checkpoints below are historical; original browser/physical-click evidence, protected WIP/old hosts/scenes/paused629/Release0.12.2 remain intact.

Direct human language request; source/compiler authoring proceeds independently of unrelated graphics consumers. Owner GPU maintains grammar/IR/trusted shader/provider contracts; CAD owns dimensional construction/native topology, Render/Viewer owns saved intent/node/TEN/history/adoption. Current source is authoritative; no external syntax imported. Preserve interaction1443 and light-object1445 scope.

Deliverable	Actual existing provider	Current implementation stage / missing gate
Typed/unit parameters	#1462 literal scalar/scene-length/degree parameters adopted82344b02; original Source0/1/2 numbers and Material uniforms/locals retained	Native and code adopted. Scene units remain distinct from native CAD units; consumer dispatch/files/display conversion and integrated UI remain separate. General dimensional algebra is PLANNED.
Calculations	#1467 two-reference quantity products adoptedc052; #1470 flat two-reference +/-/* atoms adoptedb98440be; existing Material calculations/builtins	Native and code adopted within the exact selected quantity rules. Chains, nested expressions and general scene calculations remain PLANNED; original source/ranges and old literal profile stay unchanged.
Reusable pure functions	#1454 float functions adoptedb1ee; #1456 color returns adopted363f; existing builtins/locals	Narrow Material source sugar is native and code adopted into existing IR. General functions, capture, recursion and author-body calls remain unsupported.
Conditional generation	#1482 nativea0ea09c0 adopted447ba55d; exact five-blob audit6106255503	Native and code adopted; integrated validation remains pending. Strict same-quantity two-reference<, stable PREFIX_0 and validation of all potential objects. Old separate entries retain their grammars. #1488 nativee33c1a1b/receipt6106327504 now adopted4dcb0ebb, five-blob audit6106390967; distinct mixed source profile available. No body/else/nesting; broader generation remains PLANNED. Material discrete selection and CPU sampling have separate current receipts below.
Finite loops	#1476 finite-repeat compiler adopted3833ded7; positive count1..32/eight prefixes/32 potential objects	Native and code adopted with original repeat tokens and separate generated identity. Mixed repeat/conditional #1488 is code adopted4dcb0ebb. Zero count #1494 native3bf23cc1/receipt6106441227 is code adoptedcc3f3f74, five-blob audit6106473174; index expressions and nesting remain PLANNED. No while/recursion/runtime creation.
Material vector calculations	Existing distinct linear RGB color type/hex/rgb, scalar calculations	PLANNED vec2/3/4 scope and operations/component ranges/zero normals/type compatibility; color is not general vector authority.
mix and smoothstep	Existing typed scalar/color mix; literal ordered smoothstep edges/reciprocal<=1000, canonical expansion	Existing native/adopted source capabilities reused. No duplicate card. Actual GL qualification follows selected consumer.
Noise	Existing explicit sin/cos waves	PLANNED exact algorithm/seed/domain/range/precision/derivative/work, no CPU F64/GPU F32 bit-parity claim. Need actual requested source failure before one bounded issue.
Texture sampling	1184 generic CPU texture catalog/companion; language no sampler expression	PLANNED source resource IDs/colorspace/UV/sampler stage/derivatives/copies/dimensions/filter/mips/errors plus actual texture/frame lifetime; generic catalog is not native sampling support.
Material functions/layers	Existing builtin/locals/nested color mix; adopted1454 float and1456 color functions	Opaque named composition/layer sugar PLANNED after concrete need/control. Separate BSDF/alpha/pass/depth/PBR, no layered physical claim.
Value selection	Existing continuous scalar/color mix/clamp; actual repeating-UV fract composition supplies five bounded black/white threshold CPU samples	READY selected compiler-only #1498, exact new recursive IR/profile/strict threshold/both-branch work/copies/errors in GPU-Material-Discrete-Selection-Selected-Contract.

Provider and compatibility stages

1432 nativeUV grammar,1434 full native geometry,1439 binding,1441 reflective cause ownership and1449 trusted shader strings are CPU native/code adopted separately.1449 native50b2ce8b/adoptff21085e, root6104449193. Attribute2 upload/program/frame/TEN/pixels/loss/resources remain missing; original denied52215 is not retried. Generic Engine evaluator1331 has its actual existing profile set; nativeUV evaluator is not claimed. Scene Source0/1/2 are literal ranged source families with distinct opt-in schemas/profiles, not native CAD generation. Original native F64/control/knot/rawUV/IDs stay separate from derived display/F32 buffers.

Exact future gates

Before each selected implementation: actual accepted/rejected authoring source and existing composition control, all-state duplicates, exact syntax/types/units/IR/version/profile/frame/identity/copies/work/error/compatibility plus one acceptance. Then native implementation, affected build and ONE source/API/file/cold flow; immutable clean parent/head/result receipt to soleIntegration/actualconsumer once. Adoption does not prove linked shaders, rendered pixels, editor/history or publication. No broad campaign/version publication/newWork/kernel replacement.

One1454 acceptance uses independently authored U/V formula expansion, typed declarations and actual fresh reconstruction. Later conditional/loop acceptance must prove stable generated IDs and bounds at source IR before rendering. Texture/noise/layers each need their own exact selected provider; specifications are PLANNED until those actual dependencies and source controls exist. General records/dynamic arrays/imports/BSDF closures deferred.

Prepared1456 — named palette return after actual1454 adoption

New 1456 / GPU-Material-Color-Return-Functions-Selected-Contract is PLANNED pending actualaccepted1454 parser/provider ancestry, not unrelatedgraphicsconsumers.

READY optional repeat source #1494

New #1494 / GPU-Scene-Optional-Repeat-Selected-Contract freezes the maintained zero-count need before code. NEW actual manual2/0/3 controls admit; existing positive repeat0 refuses SYNTAX; unmatched invalid radius/scale refuse while empty torus cross-field relation is not an instance certificate. All-state duplicate checks found no optional-zero GPU card. Exact current accepted parentf275e19c198bfce154b9144444c6e836ee38d992 and adopted1476 supply the repeat-only provider. Pending1488 adoption is not a required dependency; do not invent a joint profile availability gate. Root core/index/README plus three helpers new wrapper/new qualifier/private review have disjoint ownership in a new isolated checkout. New optional source API/result9/schema0, count0..32, no phantom IDs/records, original source/copies/work/error/oldpositive compatibility and ONE future file/cold flow are frozen.
