+### 十二、2026-06-17 Virtual HAL Session Diagnostics Artifact Linkage
+
+继续按本文件铁律推进：虚拟 HAL 的功能完全来源于 LinuxCNC 源程序，并且虚拟 HAL
+完全满足 Web 方式数控系统仿真系统。本批完成上一节下一步第 1 项，把 real
+simulation page 保存的 virtual HAL session snapshot 与 release diagnostics artifact 做联动，
+使保存后的 Web CNC 仿真会话可直接输出 release-ready diagnostics evidence。
+
+新增实质能力：
+
+- real simulation page 新增 session diagnostics artifact builder：
+  - `createVirtualHalSessionDiagnosticsArtifact(snapshot)`；
+  - 从保存的 session snapshot 读取 `payload.virtualHal`；
+  - 复用 snapshot 中的 virtual HAL state、simulation replacement、source compliance、
+    sim-config coverage、halcmd fixtures、motion controller matrix；
+  - 使用 `createProjectReleaseBrowserDiagnosticsArtifactValidation()` 对 snapshot
+    派生 diagnostics artifact 做 release 级验证；
+- `exportDiagnosticsArtifact()` 新增：
+  - `virtualHalSessionDiagnostics`；
+  - 未保存 session 时返回 `phase: "not-saved"` 和 missing reason；
+  - 已保存或恢复 session 后返回 `phase: "release-ready"`；
+- Browser simulation API 新增：
+  - `exportVirtualHalSessionDiagnosticsArtifact()`；
+- `saveVirtualHalSessionSnapshot()` 返回值新增：
+  - `releaseDiagnosticsReady`；
+  - `sessionDiagnostics`；
+- `restoreVirtualHalSessionSnapshot()` 返回值新增：
+  - `releaseDiagnosticsReady`；
+  - `sessionDiagnostics`；
+- AXIS simulation docs 同步公开
+  `exportVirtualHalSessionDiagnosticsArtifact()`，并说明 saved virtual HAL session
+  snapshot 会进入 browser diagnostics artifact，形成 release-ready evidence。
+
+新增/扩展验证：
+
+- `real_simulation_page_smoke.html` 覆盖：
+  - 页面 API 暴露 `exportVirtualHalSessionDiagnosticsArtifact()`；
+  - 保存 virtual HAL session 后 `releaseDiagnosticsReady === true`；
+  - 保存返回的 `sessionDiagnostics.validation.ready === true`；
+  - 保存返回的 session diagnostics 包含 complete motion controller matrix；
+  - `exportVirtualHalSessionDiagnosticsArtifact()` 输出 `phase === "release-ready"`；
+  - `exportDiagnosticsArtifact()` 内嵌 `virtualHalSessionDiagnostics.ready === true`；
+  - restore 后 session diagnostics 仍保持 release-ready；
+- `verify_axis_style_simulation_docs.mjs` 覆盖新 API 文档契约；
+- `verify_sdk_surface.sh` 继续覆盖 release diagnostics validation 与 virtual HAL source
+  evidence。
+
+关键验证：
+
+```text
+axis_style_simulation_docs_node_smoke=ok
+browser_real_simulation_page_smoke=ok
+sdk_surface_node_smoke=ok
+project_release_gate_manifest_node_smoke=ok
+project_release_artifact_url_workflow_node_smoke=ok
+project_batch_acceptance_workflow_node_smoke=ok
+project_batch_acceptance_artifact_node_smoke=ok
+git diff --check ok
+```
+
+语义边界：
+
+- 本批没有新增 G-code/interpreter/planner/kinematics/remap 语义；
+- session diagnostics artifact 只复用保存时已有的 source-derived virtual HAL reports；
+- release validation 只验证 Web 仿真所需 HAL、halcmd、motion controller evidence；
+- virtual HAL 仍不声称提供 Linux kernel hard-realtime ABI、外部硬件驱动 ABI 或 native
+  HAL module ABI；
+- G-code/interpreter/planner/canonical motion 语义仍来自 LinuxCNC-backed WASM。
+
+下一步工作内容：
+
+1. 将 ini-panel workflow overview 的 diagnostics URL workflow 接入固定页面表单/按钮，
+   让用户可在页面上输入 release artifact URL 与 browser diagnostics URL 后直接运行验证。
+2. 为 motion matrix 增加 manifest-backed source check，把 matrix 关联的 sim config
+   source files 与 vendored LinuxCNC manifest 做显式一致性验证。
+3. 将 virtual HAL session diagnostics artifact 纳入 release artifact URL workflow 的示例
+   fixtures，使 URL workflow 同时覆盖 live diagnostics 与 saved-session diagnostics。
