+四十、2026-06-13 继续执行记录：browser OPFS custom session wasm path input guard
+
+1. 本批目标。
+
+继续 staged path guard inventory 第三十五轮，收敛 browser OPFS smoke 中 custom
+session 的 `parameterWasmPath`、`toolTableWasmPath` runtime input 与 helper 生成 path
+的重复规则。
+
+2. 已完成改动。
+
+- browser smoke 新增 `opfsCustomSessionWasmPath(...)`；
+- `opfsCustomSessionPaths(...)` 改为复用该 helper 生成 custom parameter/tool-table
+  WASM path；
+- INI-derived custom session 和 explicit override session 的 runtime input
+  `parameterWasmPath` / `toolTableWasmPath` 改为走同一 helper；
+- save parameter/tool-table staging 断言的 expected WASM path 同步改为走同一 helper；
+- 未修改 OPFS bridge behavior、file-service、path-model、SDK planner、interpreter 或
+  LinuxCNC-owned runtime semantics。
+
+涉及文件：
+
+```text
+wasm-port/tests/browser/interp_smoke.html
+```
+
+3. 已完成验证。
+
+```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
+```
+
+提交建议：
+
+```text
+Guard browser OPFS custom session wasm input paths
+```
+
+4. 下一步工作建议。
+
+继续 staged path guard inventory 第三十六轮，优先扫描 browser OPFS smoke 中 custom
+session 的 repeated filename literals，判断是否值得用局部 constants 收敛；仍只加
+browser/OPFS boundary guard，不改变 LinuxCNC-owned interpreter、INI、tool、parameter
+或 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
+```
