# Collider Diagnostics Acceptance

Issue: Gitea #26 (`BS-JD-305`)

## Evidence

![Collider viewport, selected trigger inspector, and scene health panel](collider-diagnostics-live.png)

The native Wayland editor loaded `assets/levels/collider_diagnostics_showcase.scn.ron` and entered
Collider view. The captured frame shows shape overlays with meshes hidden, the scene health HUD,
the selectable Diagnostics window, and the selected trigger's hydrated status in the inspector.

## Live Results

- Box, scaled sphere/ellipsoid, and capsule overlays matched authored transforms and dimensions.
- Green ready, cyan trigger, gray disabled, and red missing states were visually distinct.
- The HUD reported `4 ready / 1 disabled / 0 warning / 1 invalid` and followed selection.
- The Diagnostics panel linked the missing finding back to its actor.
- Switching the valid box to sphere preserved useful extents and produced `Undo: Set Collider`;
  undo restored the box.
- Physics Placement rejected the missing-collider actor with the shared collider-health messages.
- Scene switching and editor shutdown completed without a panic or runtime validation error.

Packaged verification remains deferred by current project instruction.
