 | Real browser simulation priority | Active first priority | Future batches should prioritize the real UI/browser CNC simulation page, with visible machine/session loading, G-code program state, LinuxCNC-backed interpreter execution, machine readiness/status panels, toolpath/preview rendering from LinuxCNC-produced output or validated runtime events, and browser smoke coverage. First entry point: `wasm-port/runtime/ui/simulation/index.html`; gate: `wasm-port/tests/browser/verify_real_simulation_browser.sh`. See `wasm-port/docs/real-browser-simulation-priority.md`. |
-| Real browser simulation page | MVP active | `runtime/ui/simulation/index.html` loads in Chromium, exposes a selector for multiple LinuxCNC-backed test programs, runs them through interpreter WASM, and now includes reset/step/play/finish playback over LinuxCNC canonical motion events. It highlights active G-code and motion rows, updates live axis readout, moves the toolhead, and grows the executed SVG toolpath. Current program set covers square contour, Z pocket contour, incremental loop, G2/G3 arcs, and G81 drilling. |

Browser smoke verifies shell regions, tab switching, toolbar playback, and existing program execution. |
 | Simulation test program library | Active | Built-in browser simulation programs live in `wasm-port/runtime/ui/simulation/programs/`, one module per program, exported through `programs/index.js`; `verify_real_simulation_programs.sh` checks directory-backed inventory, IDs, defaults, and playback contracts. |
 | Vendor/source guard | Stable | `verify_vendor_sync.sh` and standalone semantic guard are required every batch. |

+
+八十四、2026-06-16 继续执行记录：真实 G-code 文本/文件执行
+
+用户要求程序实现跑真实的 G-code 程序。本批在保留内置测试程序库的基础上，新增 operator-provided
+G-code text 和 browser File 的执行入口。
+
+本批新增实质能力：
+
+- 页面工具栏新增 Open Program 文件入口：
+  - `data-open-program`；
+  - `data-open-program-file`；
+- `window.linuxCncRealSimulationApi` 新增：
+  - `runProgramText(programText, metadata)`；
+  - `loadProgramFile(file)`；
+- `runProgramText()` 会直接调用 `runRealBrowserSimulation({ programText })`，因此仍通过
+  LinuxCNC-backed WASM interpreter 执行；
+- `loadProgramFile(file)` 读取浏览器 File 文本，再走同一个 LinuxCNC WASM 执行路径；
+- simulation state 新增 program source metadata：
+  - `program.source`；
+  - `program.sourceLabel`；
+  - `program.filename`；
+  - `document.body.dataset.simulationProgramSource`；
+- UI 显示程序来源：
+  - G-code pane header；
+  - bottom status bar；
+- browser smoke 新增真实 G-code 验证：
+  - `runProgramText()` 执行非内置 G-code，验证 canonical output 中出现对应坐标；
+  - `loadProgramFile()` 使用 browser `File` 对象加载 `.ngc` 文本，验证修改后的 G-code 坐标
+    通过 LinuxCNC WASM 输出；
+- Node smoke 新增 custom `programText` 直接执行验证。
+
+本批新增/更新可执行验证：
+
+```bash
+wasm-port/tests/ui/node/verify_real_simulation_programs.sh
+SKIP_INTERP_BUILD=1 wasm-port/tests/browser/verify_real_simulation_browser.sh
+```
+
+关键通过输出：
+
+```text
+real_simulation_programs_node_smoke=ok
+browser_real_simulation_page_smoke=ok
+```
+
+本批仍保持 LinuxCNC 语义边界：
+
+- JS 只读取用户提供的 G-code 文本/文件；
+- G-code 执行仍交给 LinuxCNC-backed WASM；
+- JS 不解释 G-code、不规划刀路、不推导 CNC 语义。
