BetaBetadocumentThe specific document id this participant is in: a draft, published, or version id, depending on which perspective they are editing.
BetalastWhen they said they were last active, on their clock. Fine for display, unreliable for liveness. See PresenceLocation.lastActiveAt.
BetapathThe focused field path. Empty when they are in the document but no field.
Optional BetaselectionThe Portable Text caret, when they are focused in a Portable Text field.
BetasessionIdentifies one tab, so the same person in two tabs appears twice.
Betauser
One participant at one location within a single document, flattened so it can be rendered directly against a field.
Unlike PresenceLocation.path,
pathhere is typed as a fullPath, so keyed and numeric segments are described rather than cast away.
