M10-03 Status

status: done task: Geometry Nodes allowlist 逐节点 Blender 5.2 desktop/WASM golden updated: 2026-08-16 America/New_York

Scope

The headless Web modifier evaluates the saved Blender Main graph only through the 16-node schema-1 allowlist. Eleven minimal Blender 5.2 fixtures make every allowlisted node affect a measured output. The same fixture is evaluated by the full-Main WASM in Node and by the production Chromium Worker before and after save/reopen.

This is a bounded constant-scalar, topology, attribute, and same-file resource closure. It does not claim arbitrary Blender field/domain conversion, complete lazy-function semantics, Geometry Nodes graph writing, linked resources, or Simulation Zones.

Coverage

Graph boundary: Group Input and Group Output.
Geometry: Transform, Set Position, Join/Separate Geometry, Realize Instances, and Store Named Attribute with a constant Float point-domain value.
Scalar/vector: Integer, Vector, Value, Compare, and Math nodes on the bounded operations accepted by the native evaluator.
Same-file resources: Object Info, Collection Info with separate children, and Image Info dimensions. Missing, recursive, linked, or otherwise unverified resources stay behind the M10-02 resource gate.

Evidence

Fixture: tests/files/web/geometry_node_allowlist_evaluator.blend.
Golden: tests/golden/M10-03/geometry-node-evaluator.json.
Desktop generator: tools/web/generate-geometry-node-evaluator-golden.py; Blender 5.2.0 LTS emitted 11 cases, and a clean temporary regeneration matched every semantic golden field after excluding output-path-dependent fixture path/hash fields.
Node full-Main WASM: node tools/web/check-geometry-node-evaluator-golden.mjs; 16 nodes, 11 cases, maximum position error 0, RMS position error 0, and attributes passed.
Chromium: WEB_TEST_PORT=5443 npm --prefix web run test:geometry-node-evaluator-golden; unit 4/4, Node golden 1/1, and Worker open/evaluate/save/reopen 1/1 passed.
Tolerances: maximum position 1e-5, RMS position 1e-6, Float point attribute 1e-6, and bounds 1e-5.
M10-01 regression on port 5444 and M10-02 regression on port 5445 passed.
Full unit suite 131/131, typecheck, lint, production build (73 modules), local dependency checks, and git diff --check passed.

Contract

Evaluation is demand-driven from the active Group Output and is capped at 4,096 node-output evaluations. Unsupported nodes, sockets, operations, cycles, or resource states return GEOMETRY_NODES_EVALUATOR_UNSUPPORTED without claiming evaluation.
The evaluator uses Blender GeometrySet, geometry join/realize/transform helpers, evaluated dependency graph resources, and Blender mesh attributes. Three.js does not execute or approximate Geometry Nodes semantics.
The fixture and golden inventory must cover every schema-1 allowlist entry before the check starts; missing coverage fails before numeric comparison.

Rollback

Remove the bounded evaluator expansion, M10-03 generator/fixture/golden/checker, Chromium spec, package script, and this status file together. Revert the M10 count to 2/15 and restore the previous Transform/Set Position-only modifier evaluator.
