Read

启动时只读取本文件的 Current、Task、Verify、Stop，然后按需读取：

docs/linuxcnc-web-wasm-simulation-gap-plan-v2.md
docs/linuxcnc-web-wasm-autonomous-execution-prompt.md
docs/linuxcnc-web-wasm-case-parity-plan.md

  - browser performance and recovery boundary report
  - explicit Firefox/Safari/OPFS blockers without promotion
objective: >-
  在真实 Chromium production preview 中验证 GUI DOM、Three.js 非空像素、
  exact-path 三轴案例加载、控件布局和移动视口；浏览器版本矩阵、OPFS
  crash/recovery 和 Safari/Firefox 不可用条件保持独立 blocked。
non_goals:
  - 不复制桌面 GTK/Qt/Tk 窗口，不把宿主 Python/动态 loader/真实硬件变成 Web 能力
  - 不修改 ABI、protocol、schema、context lock；manifest 归属缺口保留为可定位审计项

reason: Chromium visual slice is verified; full browser minimums, Safari/Firefox and OPFS recovery remain external blockers

认领后状态改为 in_progress，完成后只能在专属测试、完整技术回归和报告 self-hash 都通过时改为 verified；发现输入或契约缺口则改为 blocked 并保留失败样本。

Verify

开始修改前：

python3 scripts/validate_baseline.py
python3 scripts/validate_task_pointer.py

技术轨道收口验证：

scripts/build-wasm.sh
ctest --test-dir build-native --output-on-failure
for f in web/worker/test_*.mjs; do node "$f" || exit 1; done
for f in web/app/test_*.mjs; do node "$f" || exit 1; done

完成任务后还必须运行：

for f in web/worker/test_*.mjs; do node "$f" || exit 1; done
for f in web/app/test_*.mjs; do node "$f" || exit 1; done
python3 scripts/validate_baseline.py
python3 scripts/validate_task_pointer.py

Stop

遇到以下任一情况立即保持 blocked：

需要修改锁定 ABI、protocol、schema 或 manifest。
native/WASM/Worker 的首个 divergent tick 未定位。
只能依赖墙钟、随机数、mock Worker、宿主路径或真实设备才能通过。
checkpoint/event/hash 不可验证，或恢复会重复已提交副作用。
直接输入缺失、生成器不确定性、索引/资源无法定位，或测试只能通过降低检查。

S8-10 原有 235-case acceptance 仍保持 blocked/STOP_RELEASE，不宣称 LinuxCNC 全功能 release。用户已授权继续全 GUI 技术移植；FE-M4-GUI-01..05 已完成 source/domain/AXIS/family/Three.js 映射，FE-M4-GUI-06 Chromium desktop/mobile visual smoke 已 verified，但三浏览器 minimum matrix、Safari/Firefox、OPFS recovery 仍 blocked；许可证审批不阻塞实现，最终交付阶段再汇总 license/NOTICE。
