subject

What a capture of an entity is a picture of. Every path that frames or isolates an entity (fromEntity, oneshot, a setups or viewpoints collage, isolate) resolves the name, id or proxy it was given here, so they agree on which entity a name means.

A player is drawn as its body

A player identity (an entity carrying UserIdentity) is the registry anchor a connected user is known by. The player is drawn as the body its avatar names, a standalone entity at the scene root, so a capture of an identity frames and isolates that body.

In play, a player prototype's spawn turns the prototype's copy into the joining user's identity under the prototype's own name and stands the body it names at the spawn point. A capture of the name an author gave their player prototype therefore frames the player's body in play, and the prototype's subtree in edit.

What a refusal names

describe(target, via) is the phrase a framing refusal uses for each subject it looked at: the entity's name and id with the number of descendants it holds, and the player identity it is the body of when it was reached through one, or, for a player identity with no live body bound, that the body is missing.
