 workflow：保存当前 INI、parameter/tool-table path 和可选 G-code snapshot，再通过
 `loadMachineSessionSnapshot(...)` 恢复出待加载文件清单。范围仍限定 OPFS/filesystem/UI
 workflow，不解析或重写任何 LinuxCNC-owned CNC 语义。
+
+五、2026-06-14 继续执行记录：INI panel session snapshot workflow
+
+本轮继续按“加快实质性推进铁律”推进可直接使用的 browser/UI workflow，把 machine
+session snapshot save/load helper 接入 INI panel 的最小会话保存/恢复流程。
+
+完成内容：
+
+- 在 `wasm-port/runtime/ui/ini-panel/app.js` 引入
+  `saveMachineSessionSnapshot(...)` 与 `loadMachineSessionSnapshot(...)`；
+- 新增固定 UI session snapshot id 与 filename：
+  `ui-machine-session/ui-machine-session.json`；
+- 新增 `Save Session Snapshot` 控件：
+  - 保存当前编辑器 INI 到 OPFS machine files；
+  - 保存默认 parameter/tool-table text；
+  - 保存默认 G-code program；
+  - 生成并保存 machine session snapshot；
+  - 回填 INI、parameter、tool-table、G-code 和 snapshot path 字段；
+- 新增 `Restore Session Snapshot` 控件：
+  - 通过 `loadMachineSessionSnapshot(...)` 读取并校验 snapshot；
+  - 从 OPFS machine files 恢复 INI 到编辑器；
+  - 回填 snapshot 中的待加载文件清单；
+- 在 `wasm-port/runtime/ui/ini-panel/index.html` 增加两个按钮和
+  `Session Snapshot` 状态字段；
+- 在 browser INI panel smoke 中覆盖保存 snapshot、恢复 snapshot、字段回填和 INI
+  文本恢复；
+- 未改变 LinuxCNC INI parser、interpreter、parameter restore/save、tool-table load/save
+  或 G-code 执行语义；
+- 未改变 OPFS path model、generic snapshot envelope、file-service、machine-session
+  bridge 或 LinuxCNC-owned runtime semantics。
+
+验证已通过：

+```
+
+下一步建议：
+
+继续推进 browser/UI workflow 的实质能力。优先把 `Restore Session Snapshot` 后的文件清单
+与现有 `Load Machine Session` 串联成单个可执行入口，例如新增
+`Restore And Load Session`：先校验 snapshot，再把 OPFS INI/parameter/tool-table 加载到
+interpreter WASM FS，并保持 G-code path 可运行。范围仍限定 OPFS/session/UI 编排，不
+解析或改写任何 CNC 语义。
