 抽取为纯 helper 并接入 `verify_ui_node_smokes.sh`；保持 helper 只描述 host/runtime 边界，
 不扩展 CNC 语义。
 
+二十四、2026-06-14 继续执行记录：INI panel machine file summary helper
+
+本轮继续沿 OPFS/session/UI boundary 推进，把 INI panel 的 machine text file save/load
+日志构造收敛为纯 helper，并接入 UI Node smoke。
+
+完成内容：
+
+- 新增 `wasm-port/runtime/ui/ini-panel/machine-file-summary.js`；
+- 导出：
+  - `createMachineFileSaveSummary(paths, gcodePath)`；
+  - `machineFileSaveLogLines(summary)`；
+  - `createMachineFileLoadSummary(files)`；
+  - `machineFileLoadLogLines(summary)`；
+- helper 只聚合 OPFS/staging boundary facts：
+  - INI/tool/parameter/G-code OPFS path；
+  - INI/tool/parameter loaded text length；
+- `wasm-port/runtime/ui/ini-panel/app.js` 的 `Save Machine Files` 和 `Load Machine Files`
+  日志改为复用该 helper；
+- 新增 `wasm-port/tests/ui/node/verify_ini_panel_machine_file_summary.mjs` 和 shell wrapper；
+- `wasm-port/tests/ui/node/verify_ui_node_smokes.sh` 现在覆盖 run/session/machine-file
+  三组 UI helper；
+- 未改变 UI runtime、OPFS bridge、interpreter run API、G-code 文本、canonical-event 输出
+  或 LinuxCNC-owned runtime semantics。
+
+验证已通过：
+
+```bash
+git diff --check
+wasm-port/tests/ui/node/verify_ini_panel_machine_file_summary.sh
+wasm-port/tests/ui/node/verify_ui_node_smokes.sh
+wasm-port/tools/verify_vendor_sync.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
+ini_panel_machine_file_summary_node_smoke=ok
+ini_panel_run_summary_node_smoke=ok
+ini_panel_session_summary_node_smoke=ok
+ui_node_smokes=ok

+opfs_file_service_node_smoke=ok
+browser_ini_opfs_smoke=ok
+browser_interp_smoke=ok
+host_wasm_opfs_browser_smokes=ok
+```
+
+下一步建议：
+
+继续沿 OPFS/session/UI boundary 推进。优先把 machine file helper 补入 UI helper docs
+索引或独立文档，确保新 helper 和 `verify_ui_node_smokes.sh` 的关系可发现；仍只做
+host/runtime boundary 文档和测试 glue，不扩展 CNC 语义。
