IComponentBridge

Remarks

⚠ An archetype knows dense ids and a panel knows names, and the map only goes one way. A ComponentTypeId is handed out in first-touch order, so it means nothing across two runs of the same program and cannot be shown to anybody. There is therefore no "what components does this entity have" call: an inspector enumerates the bridges it was given and asks each one Has.

⚠ Two kinds of component exist in the editor and both have to appear. One carries [Component] and [DataContract], so the engine's component generator declares it to SceneComponentRegistry and a compiled scene can name it; the other — Light, PrimitiveShape — is editor-side and deliberately written as its own field of the scene file, because a scene naming a type no build declares is what a content compile refuses. An inspector that showed only the first would omit the light on the light, which is the most obviously missing row in the panel.
