attestedPrincipals

Host-verified principals of currently-linked peers, keyed by the PeerId each was verified against at admission — the hosted-path analogue of the relay path's Member.principal.

Populated when this session rides a PrincipalRoster seam (a gameHosted hub whose connection source attaches principals — e.g. a KtorConnectionSource with a principalExtractor); a constant empty map on seams with no attestation concept (a gameJoin spoke, gameNode, in-memory fabrics without attached principals).
