拆分仿真测试程序目录

结论：将内置 G-code 测试程序从 simulation-app.js 移入 runtime/ui/simulation/programs/，建立一程序一模块的目录化程序库，并保持页面 API 与验证 gate 兼容。

@@ -42,6 +42,7 @@ The project is complete for the current scope when all of the following are true
 | 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. |
 | AXIS-style simulation shell | Phase 1 active | `runtime/ui/simulation/index.html` now uses an AXIS-inspired titlebar, menubar, toolbar, Manual/MDI tabs, Preview/DRO tabs, G-code pane, machine-state pane, and status bar while preserving current LinuxCNC-backed execution and playback APIs. 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. |
 | Interpreter WASM smoke | Stable | `interp_wasm_node_smoke=ok`. |
 | Sim config inventory | Stable with skips | `executed=28`, `passed=28`, `skipped=131`, `unexpected_fail=0`; `docs/sim-configs-coverage-handoff.md` records the release-gate baseline. |
