+三十八、2026-06-13 继续执行记录：browser OPFS custom session path helper guard
+
+1. 本批目标。
+
+继续 staged path guard inventory 第三十三轮，收敛 browser OPFS smoke 中 custom
+session 的 session path/backup path 组合重复：
+
+```text
+browser-ini-file-session
+browser-ini-override-session
+```
+
+2. 已完成改动。
+
+- browser smoke 新增 `opfsCustomSessionPaths(...)`；
+- INI-derived custom session 和 explicit override session 的 session staging path
+  map 改为走 helper；
+- helper 统一生成 custom parameter/tool-table OPFS path 与对应 WASM path map；
+- 保留 `browser-custom.var` / `browser-explicit.var` 等文件名显式可见；
+- 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_sim_configs_inventory_wasm.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+提交建议：
+
+```text
+Guard browser OPFS custom session path helper
+```
+
+4. 下一步工作建议。
+
+继续 staged path guard inventory 第三十四轮，优先扫描 browser OPFS smoke 中
+saved parameter/tool-table readback 的 backup path 命名、以及 custom session session-path
+组合是否还能进一步分层为更小的 path helper；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
