目标

以一个共享 Blender Main reader、WASM build、Worker 路由和 Chromium receipt 批量验证 CompositorNodeNormalize, CompositorNodeOutputFile, CompositorNodePixelate, CompositorNodePlaneTrackDeform, CompositorNodePosterize, CompositorNodePremulKey, CompositorNodeRGBToBW, CompositorNodeRLayers 的真实 modifier/RNA 元数据。

输入与范围

• Blender modifier sources: blender-5.2.0/source/blender/modifiers/intern/
• RNA source: blender-5.2.0/source/blender/makesrna/intern/rna_modifier.cc
• Native reader: blender-5.2.0/source/blender/web_engine/web_engine_blend_reader.cpp
• Fixtures: tests/files/web/generated/wbv2-compositor-bf66c685c7c6fd95.blend
• Chromium test: web/tests/e2e/compositor-main-reader-production.spec.ts
• Selected modifier units: modifier-source:CompositorNodeNormalize, modifier-source:CompositorNodeOutputFile, modifier-source:CompositorNodePixelate, modifier-source:CompositorNodePlaneTrackDeform, modifier-source:CompositorNodePosterize, modifier-source:CompositorNodePremulKey, modifier-source:CompositorNodeRGBToBW, modifier-source:CompositorNodeRLayers
• Selected RNA units: none (source-only dependency batch)

验收

• one shared Main/WASM/Worker/Chromium chain observes every selected type
• malformed input is rejected without Main mutation
• save/reopen and deterministic second read are exact
• only Chromium is used; JS simulation and per-API duplicate workers are forbidden
• each selected source unit receives an explicit hash-bound coverage binding
• node tools/web/check-task-context.mjs --task WBV2-P1172-001 --write

失败边界

• any missing source, unsupported type, hash drift, malformed data or non-exact recovery keeps the batch in_progress/blocked
• partial batch success never claims the omitted family; historical inventory remains read-only
