 继续小批量扫描 browser staging path literal。优先看 custom INI-named / explicit session
 的 `iniFileIniWasmPath`、`iniOverrideIniWasmPath` 是否能复用一个 session INI WASM
 path helper；只改测试胶水，不改变 staging path 字符串或 custom filename 输入。
+
+十八、2026-06-14 继续执行记录：browser OPFS custom session INI wasm path helper guard
+
+本轮按上一条下一步建议继续扫描 custom INI-named / explicit session 的 INI WASM path
+literal，范围仍只触及 `wasm-port/tests/browser/interp_smoke.html` 的 browser/OPFS
+test glue。
+
+完成内容：
+
+- 将 `iniFileIniWasmPath` 改为复用 `opfsMachineIniWasmPath(iniFileMachineId)`；
+- 将 `iniOverrideIniWasmPath` 改为复用 `opfsMachineIniWasmPath(iniOverrideMachineId)`；
+- 未改变实际 `/work/browser-ini-file-session.ini`、
+  `/work/browser-ini-override-session.ini` staging path 字符串；
+- custom parameter/tool-table filename 输入仍在测试处外显；
+- 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
+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：
+
+继续小批量扫描 browser staging path literal。优先看 custom session 中
+`opfsCustomSessionWasmPath(...)` 调用是否还有重复 filename-derived WASM path 可用
+局部变量收敛；只改测试胶水，不改变 custom filename 输入或 path 字符串。
