+二十五、2026-06-13 继续执行记录：browser machine text-store staging guard
+
+1. 本批目标。
+
+继续 staged path guard inventory 第二十轮，处理 browser OPFS/machine text store 默认
+OPFS path 对账：
+
+```text
+linuxcnc/machines/<machine>/machine.ini
+linuxcnc/machines/<machine>/tool.tbl
+linuxcnc/machines/<machine>/linuxcnc.var
+```
+
+2. 已完成改动。
+
+- browser 侧新增 `assertMachineTextStorePaths(...)`；
+- `browser-interp` 的 `saveMachineTextFiles(...)` 返回 path map 增加默认 OPFS path
+  guard；
+- `browser-random-toolchanger` 的 `saveMachineTextFiles(...)` 返回 path map 增加默认
+  OPFS path guard；
+- `browser-ini-file-session` 与 `browser-ini-override-session` 的 machine text-store
+  path map 增加默认 OPFS path guard；
+- invalid parameter/tool INI negative session 的 machine text-store path map 增加默认
+  OPFS path guard；
+- 未修改 OPFS file-service、machine-file-store、path-model、machine file 内容或
+  session runtime semantics。
+
+涉及文件：
+
+```text
+wasm-port/tests/browser/interp_smoke.html
+```
+
+3. 已完成的目标验证。
+
+```bash
+git diff --check
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_interp_browser.sh
+```
+
+4. 本批剩余建议验证。
+
+```bash
+wasm-port/tools/verify_vendor_sync.sh
+wasm-port/tools/verify_no_standalone_cnc_semantics.sh
+SKIP_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_interp_wasm.sh
+SKIP_INTERP_BUILD=1 wasm-port/tests/wasm/node/verify_sim_configs_inventory_wasm.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+如果通过，提交建议：
+
+```text
+Guard browser machine text-store staging
+```
+
+5. 下一步工作建议。
+
+继续 staged path guard inventory 第二十一轮，优先扫描 OPFS gcode program storage
+边界，例如 `saveGcodeProgram(...)` / `loadGcodeProgram(...)` 与
+`linuxcnc/gcode/<filename>` path 对账；仍只加 filesystem/OPFS path guard，不改变
+gcode storage、file-service 或 interpreter runtime semantics。
+
+下一轮第一条命令仍保持：
+
+```bash
+git status --short && git log -5 --oneline && tail -n 120 text7.txt && awk '/^[一二三四五六七八九十百]+、/ {print}' text7.txt | sort | uniq -d
