 | LinuxCNC semantic boundary | Stable | JS/browser remains glue, staging, OPFS, WASM/browser boundary, docs, and tests only. |
 | 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 | Planned | Implementation plan exists at `wasm-port/docs/axis-style-simulation-implementation.md`; next batch should build the AXIS-inspired shell while preserving current LinuxCNC-backed execution and playback APIs. |
 | 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. |

 - Playback controls now expose reset/step/play/finish over LinuxCNC canonical

 - It should use OPFS/session persistence, staged G-code, and existing
   LinuxCNC-backed WASM SDK execution.
