+项目整体完成情况与后续执行计划
+
+生成时间：2026-06-15 CST
+
+本文件接替 `text11.txt`。后续工作按 `text12.txt` 执行；除非明确要求审计旧记录，
+不要再回到 `text1/text2/text3/text4/text5/text6/text7/text8/text9/text10/text11`
+扩展进度。`text11.txt` 作为历史归档保留。
+
+一、第一原则：加快实质性推进
+
+后续批次必须以“实质性能力优先”为第一遵守原则。
+
+1. 优先级从高到低：
+
+- OPFS/session persistence；
+- SDK/API surface；
+- browser/UI workflow；
+- sim config coverage promotion；
+- host/runtime boundary proof；
+- 文档化可执行工作流。
+
+2. 每批默认应产出至少一种可直接复用的能力：
+
+- 可调用 helper；
+- 可复用 API；
+- 可验证用户流程；
+- 可执行 gate；
+- 可提升覆盖面的 runtime boundary proof；
+- 能直接指导下一步实现的设计/清单。
+
+3. 暂停低收益推进：
+
+- 不再把“局部常量化、路径变量收敛、断言分组整理”作为主目标；
+- 只有当它支撑可复用 workflow/API/gate 时，才允许做测试胶水；
+- 禁止为了推进而扩大 CNC 语义边界；
+- 禁止启动性能测试，除非已有明确用户流程需要性能基线。
+
+4. LinuxCNC 仍是唯一 CNC 语义来源：
+
+- G-code、remap、tool、parameter、planner、kinematics、user-M、tool DB、Python remap
+  等语义必须来自 LinuxCNC upstream 或 vendored LinuxCNC C/C++/配置/脚本源码；
+- JS/browser 只允许做 build、source sync、runtime shim、filesystem staging、OPFS、
+  WASM/browser boundary、测试胶水、文档和机器可读 gate/artifact；
+- 不在 JS 中重写 G-code 或 CNC 语义；
+- 不修改 vendored LinuxCNC 源文件来让测试通过；
+- 不把 full-process/HAL/UI/Python/tool DB 依赖伪装成 standalone pass；
+- 不把 expected failure 硬改成 pass，除非已有 LinuxCNC-owned runtime proof，并且
+  native、Node、browser gate 都按顺序通过；
+- browser 不能依赖目录枚举。
+
+二、续接状态与防重规则
+
+1. 当前续接点。
+
+`text11.txt` 已推进到：
+
+```text
+二十四、2026-06-15 继续执行记录：INI panel control-page refresh workflow helper
+```
+
+该批已提交：
+
+```text
+ed5d03e 推进 INI 面板 control-page refresh workflow helper
+```
+
+本文件从 `text12.txt` 重新开始记录后续进度。
+
+2. 每轮开始前必须先执行：
+
+```bash
+git status --short
+git log -5 --oneline
+tail -n 120 text12.txt
+awk '/^[一二三四五六七八九十百]+、/ {print}' text12.txt | sort | uniq -d
+```
+
+执行规则：
+
+- 如果 `git status --short` 是 clean，且最新提交已经包含当前建议工作，不要重复追加记录；
+- 每轮只追加一个新的中文编号记录；
+- 提交前再次检查标题唯一性；
+- `text12.txt` 只记录新的后续进度，不复制 `text11.txt` 的长历史；
+- 每批完成后，如果要写记录，先写 `text12.txt`，再提交该批代码和记录；
+- 如果发现重复记录，先做 dedupe 清理并提交，再继续新功能或新 guard；
+- `text11.txt` 不再追加新进度，除非明确要求审计或修正历史记录。
+
+三、当前完成情况摘要
+
+1. 当前工作树状态。
+
+切换到 `text12.txt` 前已确认：
+
+```text
+git status --short: clean
+```
+
+当前最近提交：
+
+```text
+ed5d03e 推进 INI 面板 control-page refresh workflow helper
+213514f 推进 INI 面板 shell view-model helper
+b330f7b 推进 INI 面板 launcher link view-model helper
+ac46345 推进 INI 面板 entry docs strict gate
+ef4769b 推进 INI 面板 entry doc
+```
+
+2. 关键基线保持稳定。
+
+- `linuxcnc/nc_files` native Layer 1：
+  - `total 107`
+  - `pass 101`
+  - `expected_fail 6`
+  - `unexpected_fail 0`
+- `linuxcnc/configs/sim` native Layer 2：
+  - `total 159`
+  - `pass 151`
+  - `expected_fail 8`
+  - `unexpected_fail 0`
+- Node sim-config inventory：
+  - `executed=28`
+  - `passed=28`
+  - `skipped=131`
+  - `unexpected_fail=0`
+
+3. blocked runtime family 仍未 promotion。
+
+仍 blocked，不允许 promotion：
+
+- `L4-USER-M-PROCESS`
+- `L4-TOOL-DB`
+- `L4-PYTHON-REMAP`
+
+当前 host 仍按缺少 LinuxCNC host runtime 处理，不执行任何：
+
+```bash
+ENABLE_MILLTURN_USER_M_RUNTIME_PROBE=1 bash wasm-port/tests/native/probe_millturn_user_m_runtime.sh
+ENABLE_TOOL_DB_RUNTIME_PROBE=1 bash wasm-port/tests/native/probe_tool_db_runtime.sh
+ENABLE_PYTHON_REMAP_RUNTIME_PROBE=1 bash wasm-port/tests/native/probe_python_remap_runtime.sh
+```
+
+四、当前实质能力进展
+
+1. INI panel/UI helper 能力。
+
+当前 UI helper 已覆盖：
+
+- run summary；
+- run workflow；
+- session snapshot summary；
+- session load summary；
+- machine file save/load summary；
+- panel state summary；
+- session snapshot save/restore workflow；
+- entry manifest、launcher link view-model、shell view-model；
+- read-only control-page controller；
+- read-only control-page refresh workflow。
+
+当前聚合验证入口：
+
+```bash
+wasm-port/tests/ui/node/verify_ui_node_smokes.sh
+```
+
+当前 `verify_ui_node_smokes.sh` 覆盖：
+
+```text
+ini_panel_run_summary_node_smoke=ok
+ini_panel_run_workflow_node_smoke=ok
+ini_panel_session_summary_node_smoke=ok
+ini_panel_session_workflow_node_smoke=ok
+ini_panel_machine_file_summary_node_smoke=ok
+ini_panel_state_summary_node_smoke=ok
+ini_panel_control_page_controller_node_smoke=ok
+ini_panel_control_page_refresh_workflow_node_smoke=ok
+ini_panel_entry_manifest_node_smoke=ok
+ini_panel_ui_shell_node_smoke=ok
+ini_panel_entry_docs_node_smoke=ok
+ui_node_smokes=ok
+```
+
+2. Browser/UI workflow 验证。
+
+当前 browser INI panel smoke 覆盖真实 OPFS/session persistence workflow：
+
+```bash
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_ini_panel_browser.sh
+```
+
+关键输出：
+
+```text
+browser_ini_opfs_smoke=ok
+browser_ini_control_page_smoke=ok
+browser_ini_launch_smoke=ok
+```
+
+五、当前必须保持通过的验证入口
+
+每批后续改动至少运行：
+
+```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_ini_panel_browser.sh
+wasm-port/tests/ui/node/verify_ui_node_smokes.sh
+wasm-port/tests/host/verify_host_smokes.sh
+```
+
+如果涉及 browser interpreter smoke，再运行：
+
+```bash
+SKIP_INI_BUILD=1 SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_interp_browser.sh
+```
+
+涉及 native baseline 或大范围 source/staging 改动时，再运行：
+
+```bash
+wasm-port/tests/native/verify_nc_files.sh
+wasm-port/tests/native/verify_sim_configs.sh
+```
+
+六、下一步建议
+
+继续推进 OPFS/session persistence 的实质链路。下一批建议抽出
+`loadMachineSessionForControlPageWorkflow()` 或等价 helper，让 read-only control page 能以明确
+状态模型描述 embedded panel API readiness 和首帧 session state；仍保持只读，不新增控制按钮，
+不解析 G-code。
+
+一、2026-06-15 继续执行记录：INI panel control-page session readiness workflow helper
+
+本轮按“第一原则：加快实质性推进”切换到 `text12.txt` 续接，并推进 OPFS/session
+persistence 相关 browser/UI workflow：新增 read-only control-page session readiness workflow，
+让外层页面能以明确状态模型读取 embedded panel API readiness 和首帧 session state。
+
+完成内容：
+
+- 新建 `text12.txt`，接替 `text11.txt`；后续记录从本文件继续；
+- 新增 `wasm-port/runtime/ui/ini-panel/control-page-session-workflow.js`；
+- 新增 `createControlPageSessionLoadState(input)`，固定 control-page session load 状态结构；
+- 新增 `loadMachineSessionForControlPageWorkflow(input)`，统一描述：
+  - `waiting-panel`：embedded panel frame 尚不可读；
+  - `waiting-api`：panel window 可读但 API 尚未暴露；
+  - `waiting-session`：API 已可读但 control view 尚未就绪；
+  - `ready`：state bundle、workflow status 和 control view 可读取；
+  - `error`：读取 panel window/API/control view 时失败；
+- `createMachineSessionControlPageController()` 新增 `loadSessionState()`；
+- `control-page.js` 对浏览器页面暴露 `loadControlPageSessionState`；
+- `ui-shell.js` re-export session readiness workflow helper，并在
+  `createIniPanelShellViewModel()` 中暴露 `controlPage.loadSessionState`；
+- 新增 `wasm-port/tests/ui/node/verify_ini_panel_control_page_session_workflow.mjs` 和 `.sh`；
+- `verify_ui_node_smokes.sh` 纳入 session readiness workflow smoke；
+- browser control-page smoke 验证 `loadControlPageSessionState().phase === "ready"`；
+- `panel-entry.md` 和 entry docs gate 同步记录 session readiness workflow API；
+- 未新增控制按钮；
+- 未解析 G-code；
+- 未解释 canonical events；
+- 未改变 OPFS/session persistence、LinuxCNC interpreter、tool、parameter、planner 或
+  LinuxCNC-owned runtime semantics。
+
+验证已通过：

+```
+
+下一步建议：
+
+继续推进 OPFS/session persistence 的实质链路。下一批建议把 `load-session` 按钮路径抽成
+`loadMachineSessionIntoWasmWorkflow()`，统一返回 loaded session、load summary、field state 和
+log lines；仍保持由 LinuxCNC/OPFS bridge 执行实际语义，不在 JS 中解释 CNC 行为。
