| Area | Status | Notes |
|---|---|---|
| Docs checklist + /l5 try page | done | This docs section and /l5 landing page exist. |
| Lua source detection (.lua) in loader | done | disk + parse support .lua, including .mjs -> .lua -> .lisp fallback. |
| Lua runtime adapter (Wasmoon) | done | Wasmoon runtime is vendored and wired through lib/l5.mjs. |
| L5 lifecycle bridge (setup/draw/events) | in progress | setup/draw + key/mouse callbacks are mapped; advanced callbacks remain. |
| Core graphics API parity | in progress | background/fill/stroke/line/rect/circle/ellipse/text/triangle/quad mapped. |
| Input globals (mouse/key/frame) | in progress | mouse/key/frame globals are injected each frame; parity is still incomplete. |
| Publish .lua pieces | done | Upload + media tracking now accept lua extension. |
| Trust/restricted API posture for Lua | done | Lua pieces use trustLevel=l5 and run through restricted API policy. |
