 继续小批量 browser OPFS test glue guard。优先扫描 custom session 中 filename groups
 是否还能和 path/load/staging helper 对齐为 locals；只改测试胶水，不改变 custom
 filename 输入、OPFS path、WASM path 字符串或保存/读取行为。
+
+三十四、2026-06-14 继续执行记录：browser OPFS INI-named session file group helper guard
+
+本轮按上一条下一步建议继续收敛 custom session filename groups，范围仍只触及
+`wasm-port/tests/browser/interp_smoke.html` 的 browser/OPFS test glue。
+
+完成内容：
+
+- 新增 `opfsCustomSessionFiles(...)`，统一 custom session parameter/tool-table
+  filename 与对应 WASM path 的派生；
+- INI-named session 的 `browser-custom.var` 与 `browser-custom-tool.tbl` 改为通过
+  `opfsCustomSessionFiles(...)` 生成 filename group；
+- INI-named session 的 parameter/tool-table WASM paths 改为复用该 filename group
+  派生出的 `/work/<filename>` paths；
+- 实际 custom filename 输入、OPFS path、WASM path 字符串与 save/read 行为均未改变；
+- 未改变 staging path 模型、OPFS bridge behavior、file-service、SDK planner、
+  interpreter、INI、tool、parameter 或 LinuxCNC-owned runtime semantics。
+
+验证已通过：
+
+```bash
+git diff --check
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_interp_browser.sh
+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
+```
+
+关键输出：
+
+```text
+browser_interp_smoke=ok
+vendor sync up to date
+standalone CNC semantics guard complete
+interp_wasm_node_smoke=ok

+```
+
+下一步建议：
+
+继续小批量 browser OPFS test glue guard。优先扫描 explicit override session 的
+filename group 是否也能复用 `opfsCustomSessionFiles(...)`；只改测试胶水，不改变
+custom filename 输入、OPFS path、WASM path 字符串或保存/读取行为。
