目标

以一个共享 Blender Main reader、WASM build、Worker 路由和 Chromium receipt 批量验证 ANIM_OT_keyframe_delete 的真实 modifier/RNA 元数据。

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/basic_scene.blend
Chromium test: web/tests/e2e/wbv2-object-delete-batch-production.spec.ts
Selected modifier units: modifier-source:ANIM_OT_keyframe_delete
Selected RNA units: none (source-only dependency batch)

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-P1315-001 --write

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
