+三十四、2026-06-13 继续执行记录：browser OPFS invalid session staging guard
+
+1. 本批目标。
+
+继续 staged path guard inventory 第二十九轮，收敛 browser OPFS smoke 中 invalid INI
+parameter/tool-table rejection 的重复 staging guard：
+
+```text
+browser-invalid-param-file-session
+browser-invalid-tool-file-session
+```
+
+2. 已完成改动。
+
+- browser smoke 新增 `verifyOpfsInvalidIniSessionRejects(...)`；
+- invalid parameter-file session 改为通过 helper 保存 machine text、校验默认 OPFS
+  machine text paths、校验 INI staging path，再验证 expected rejection；
+- invalid tool-table session 改为通过同一 helper 走相同 staging/rejection guard；
+- 保留 LinuxCNC-owned INI filename validation 的错误期望，不改变 OPFS bridge behavior、
+  file-service、path-model、SDK planner、interpreter 或 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 invalid session staging
+```
+
+4. 下一步工作建议。
+
+继续 staged path guard inventory 第三十轮，优先扫描 browser OPFS smoke 中 save
+parameter/tool-table 后的 explicit `assertOpfsParameterStaging(...)`、
+`assertOpfsToolTableStaging(...)` 是否还能按 save-operation helper 小批收敛；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
