InspectorPanel shows EditorState.Selected's Transform (Position/Scale as draggable Vector3 widgets, Rotation shown read-only as a quaternion — a real rotate control needs Euler conversion or a gizmo, out of scope for just the Inspector) and, below it, every attached Component's public fields via reflection. No per-component-type drawer code exists anywhere: int/float/bool/string/Vector3 fields get a live-editable widget, anything else falls back to a read-only ToString(), and a brand new component type in any plugin gets an Inspector for free the moment it's attached — that genericity is the entire reason to do this by reflection instead of a registry. Field edits write straight back through FieldInfo.SetValue, same gap GameObject.AddComponent's doc comment already names: components are plain fields with nothing to intercept a direct mutation, so this needs no SystemAccessScope declaration any more than a hand-written `component. Value = 5` would. EditorPlugin now defaults EditorState.Selected to the first root once, if nothing's been clicked yet — an empty Inspector on every fresh launch had nothing useful to show. Verified by screenshot: Inspector displays "Quad"'s real Position (0,0,0) and Scale (2,2,1), matching scene.json exactly, plus a QuadRenderer header correctly showing "(no fields)" since it has none yet. Full suite still green: 65 tests. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N1qPfzq8TDCUMFMV3UwV5N
