 `interp_smoke.html` 中 OPFS custom session helpers 周边是否还有硬编码
 `machine.ini`、`linuxcnc.var`、`tool.tbl` default path literal 可安全接入既有
 path helper；只改测试胶水，不改变 path model 或 runtime bridge。
+
+十三、2026-06-14 继续执行记录：browser OPFS default machine path helper guard
+
+本轮按上一条下一步建议继续扫描 OPFS custom/default session helper 周边的 default
+machine file path literal，范围仍只触及 `wasm-port/tests/browser/interp_smoke.html`
+的 browser/OPFS test glue。
+
+完成内容：
+
+- 在 `assertMachineTextStorePaths(...)` 中复用 `opfsMachineFilePath(...)` 生成默认
+  `machine.ini`、`tool.tbl`、`linuxcnc.var` expected OPFS paths；
+- 在 `assertOpfsSessionStaging(...)` 中复用同一 helper 生成默认 INI、parameter、
+  tool-table OPFS paths；
+- custom session override 仍通过 `expectedPaths.opfs` 显式覆盖，路径模型行为未改；
+- 未改变 OPFS bridge behavior、file-service、path-model、SDK planner、interpreter、
+  INI、tool、parameter 或 LinuxCNC-owned runtime semantics。
+
+验证已通过：
+
+```bash
+git diff --check
+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
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_interp_browser.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+关键输出：
+
+```text
+vendor sync up to date
+standalone CNC semantics guard complete
+interp_wasm_node_smoke=ok
+sim_configs_wasm_node_inventory_executed=28
+sim_configs_wasm_node_inventory_passed=28
+sim_configs_wasm_node_inventory_skipped=131
+sim_configs_wasm_node_inventory_unexpected_fail=0
+browser_interp_smoke=ok
+host_wasm_opfs_browser_smokes=ok
+```
+
+下一步建议：
+
+继续保持小批量 browser/OPFS boundary guard。优先扫描 OPFS default filename
+`machine.ini`、`linuxcnc.var`、`tool.tbl` 是否值得抽成局部常量，只限
+`interp_smoke.html` test glue；如果收益不明显，转向其它 browser staging path
+literal guard。
