# Real Browser Simulation Priority
|
|
|
|
This document is a standing project constraint for all work after 2026-06-16.
|
|
|
|
## Primary Objective
|
|
|
|
The first priority is to deliver a real browser CNC simulation page, not more
|
|
project metadata or dashboard-only helpers. Future batches should prefer
|
|
visible, interactive browser capability that moves the product toward an
|
|
operator-usable CNC simulation surface.
|
|
|
|
The target page must become a real CNC simulation page with:
|
|
|
|
- a machine/session loader backed by the existing OPFS/session workflow;
|
|
- a G-code program view backed by persisted or staged program text;
|
|
- LinuxCNC-backed interpreter execution through the existing WASM SDK;
|
|
- machine state panels for run status, active program, machine files, and
|
|
missing readiness;
|
|
- a toolpath/preview area driven by LinuxCNC-produced interpreter/canonical
|
|
output or existing validated runtime events, not JavaScript-owned CNC
|
|
semantics;
|
|
- browser smoke coverage that proves the page loads, renders nonempty runtime
|
|
state, and can run a representative LinuxCNC-backed program flow.
|
|
|
|
The first implementation entry point is:
|
|
|
|
```text
|
|
runtime/ui/simulation/index.html
|
|
```
|
|
|
|
Its browser gate is:
|
|
|
|
```bash
|
|
wasm-port/tests/browser/verify_real_simulation_browser.sh
|
|
```
|
|
|
|
The current page includes a real LinuxCNC-backed test-program selector and
|
|
motion playback controls. The browser gate runs each listed program through the
|
|
WASM interpreter and verifies that rendered program rows, canonical output,
|
|
motion rows, active-line playback, executed toolpath points, moving toolhead,
|
|
and declared motion types stay aligned with LinuxCNC-produced output. The first
|
|
program set covers linear contouring, Z moves, incremental mode, G2/G3 arcs,
|
|
and G81 drilling.
|
|
|
|
## Batch Priority
|
|
|
|
Unless a user explicitly changes priority, choose work in this order:
|
|
|
|
1. Real UI/browser simulation page capability.
|
|
2. Browser workflow smoke for that simulation capability.
|
|
3. UI APIs needed by the simulation page.
|
|
4. OPFS/session integration needed by the simulation page.
|
|
5. SDK/API helpers only when they directly unblock the simulation page.
|
|
6. Documentation or release metadata only when it creates an executable gate or
|
|
protects the simulation-page direction.
|
|
|
|
Every implementation batch still must produce at least one callable API,
|
|
verifiable workflow, executable gate, or real UI/browser capability.
|
|
|
|
## Boundary Rules
|
|
|
|
The browser simulation page must not implement CNC semantics in JavaScript.
|
|
G-code interpretation, canonical motion behavior, tool semantics, parameter
|
|
semantics, kinematics, remap behavior, and planner behavior must remain owned by
|
|
vendored LinuxCNC source and existing LinuxCNC-backed WASM C ABI boundaries.
|
|
|
|
JavaScript/browser code may own:
|
|
|
|
- layout and interaction state;
|
|
- OPFS/session persistence;
|
|
- file staging into the Emscripten filesystem;
|
|
- calls into the SDK/WASM boundary;
|
|
- rendering LinuxCNC-produced output, canonical events, and validated runtime
|
|
summaries;
|
|
- non-CNC UI state such as selected file, active tab, viewport mode, and
|
|
validation messages.
|
|
|
|
## Required Evidence
|
|
|
|
The priority is enforced by:
|
|
|
|
```bash
|
|
wasm-port/tests/docs/node/verify_real_browser_simulation_priority_docs.sh
|
|
wasm-port/tests/ui/node/verify_real_simulation_programs.sh
|
|
wasm-port/tests/host/verify_host_smokes.sh
|
|
wasm-port/tests/host/verify_project_release_gate.sh
|
|
```
|
|
|
|
The docs gate must verify that this priority document, the release handoff, the
|
|
README, and `PROJECT_COMPLETION_TRACKER.md` all point future work toward a real
|
|
browser CNC simulation page while preserving the LinuxCNC semantic boundary.
