 verification helper。优先只收敛 `wasm-port/tests/browser/interp_smoke.html` 中
 `saveMachineParametersToOpfs(...)` / `saveMachineToolTableToOpfs(...)` 的 result
 校验胶水，不改变 expected text，不触碰 runtime bridge 与 LinuxCNC 语义。
+
+八、2026-06-14 继续执行记录：browser OPFS save result helper guard
+
+本轮按上一条下一步建议继续推进 OPFS save result verification 小批收敛，范围仍只触及
+`wasm-port/tests/browser/interp_smoke.html` 的 browser/OPFS test glue。
+
+完成内容：
+
+- 新增 `verifyOpfsSaveResult(...)`，统一 OPFS save helper result 的
+  `verifyExpectedOutput(...)` 精确校验入口；
+- 收敛 `saveMachineParametersToOpfs(...)` / `saveMachineToolTableToOpfs(...)`
+  后续 7 个 result 校验调用；
+- expected output 行内容未改，只把 `.result` 读取和 `join("\n")` 胶水放入 helper；
+- 未改变 OPFS bridge behavior、file-service、path-model、SDK planner、interpreter、
+  INI、tool、parameter 或 LinuxCNC-owned runtime semantics。
+
+验证已通过：
+
+```bash
+git diff --check
+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
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_interp_browser.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+关键输出：
+
+```text
+vendor sync up to date
+standalone CNC semantics guard complete
+interp_wasm_node_smoke=ok
+sim_configs_wasm_node_inventory_executed=28
+sim_configs_wasm_node_inventory_passed=28
+sim_configs_wasm_node_inventory_skipped=131
+sim_configs_wasm_node_inventory_unexpected_fail=0
+browser_interp_smoke=ok
+host_wasm_opfs_browser_smokes=ok
+```
+
+下一步建议：
+
+继续沿 browser/OPFS boundary guard 方向小批量推进。优先扫描
+`wasm-port/tests/browser/interp_smoke.html` 里 OPFS load result 的重复
+`verifyExpectedOutput(...)` 调用，若 `loadedSession.parameters.result` /
+`loadedSession.toolTable.result` 等形态足够一致，可抽一个只处理 result 精确校验的
+helper。仍不改变 expected text，不触碰 runtime bridge、file-service 或 LinuxCNC
+语义。
