+三十六、2026-06-13 继续执行记录：browser OPFS readback staging guard
+
+1. 本批目标。
+
+继续 staged path guard inventory 第三十一轮，收敛 browser OPFS smoke 中 saved
+parameter/tool-table readback 的重复 `loadTextFile(...)` 验证。
+
+2. 已完成改动。
+
+- browser smoke 新增 `verifyOpfsReadback(...)`；
+- saved parameter backup、INI-derived parameter text、INI-derived parameter backup、INI-derived
+  tool-table text、explicit parameter text、explicit parameter backup、explicit tool-table text
+  的读回验证改为走 readback helper；
+- helper 只包装 `loadTextFile(...)` + `verifyExpectedOutput(...)`，不改变 readback 语义；
+- 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 readback staging
+```
+
+4. 下一步工作建议。
+
+继续 staged path guard inventory 第三十二轮，优先扫描 browser OPFS smoke 中
+saved backup path 的 explicit variable names、backup file naming、以及 file-content text
+fixture 的 inline path 重复，挑选仍可收敛为更小的 readback/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
