- task: M16-GAP-00133
- parent: M16-GAP-00132
- status: in_progress
- gap: operator:action.select_all
- ownerFamily: OPERATOR
- targetImplementationClass: LOCAL_EXACT

## 目标

Make the same minimal fixture produce observable operator:action.select_all data in Blender desktop and WASM/Main, with save/reopen stability. Change only this gap; do not expand to other data-blocks, editors, or browsers.

## 输入与范围

- Fixture: `tests/files/web/generated/M16-GAP-00133-operator-action.select_all.blend`
- Generator: `tools/web/generated/M16-GAP-00133.py`
- Production: `blender-5.2.0/source/blender/web_engine/web_engine_blend_reader.cpp`
- Checker: `tools/web/check-generated-gap.mjs`
- Do: field read, desktop/WASM comparison, save/reopen, structured report.
- Do not: other gaps, Firefox/WebKit, or full editor behavior.

## 验收

build_blender_5.2.0/bin/blender -b --factory-startup --python tools/web/generated/M16-GAP-00133.py -- tests/files/web/generated/M16-GAP-00133-operator-action.select_all.blend
npm --prefix web run test:generated-gap -- --task M16-GAP-00133
node tools/web/check-generated-gap.mjs --task M16-GAP-00133

Malformed/unsupported, cancellation, duplicate, over-budget, or hash-drift cases must keep in_progress; they must not change Main revision or advance nextTask.
