+三十二、2026-06-13 继续执行记录：browser OPFS session staging guard
+
+1. 本批目标。
+
+继续 staged path guard inventory 第二十七轮，收敛 browser OPFS smoke 中普通 session
+与 random toolchanger session 的重复 inline staging 断言：
+
+```text
+loadMachineSessionFromOpfs(...)
+browser-interp
+browser-random-toolchanger
+```
+
+2. 已完成改动。
+
+- browser smoke 新增 `assertOpfsSessionStaging(...)`；
+- 普通 `browser-interp` session 的 INI、tool table、parameter path 断言改为走 session
+  helper；
+- `browser-random-toolchanger` session 的 INI、tool table、parameter path 断言改为走
+  session helper；
+- 保留既有 `assertOpfsIniStaging(...)`、`assertOpfsToolTableStaging(...)`、
+  `assertOpfsParameterStaging(...)` 单项 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

+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 session staging
+```
+
+4. 下一步工作建议。
+
+继续 staged path guard inventory 第二十八轮，优先把 browser OPFS smoke 中 INI-derived
+和 explicit override session 的 `assertOpfsIniStaging(...)`、`assertOpfsToolTableStaging(...)`、
+`assertOpfsParameterStaging(...)` 三件套收敛到 session-aware helper，但保留 custom
+filename 的显式 expected OPFS path；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
+```
