Session name-claim outcomes are built out but availability is set by remote config.
What
Claiming a session name now resolves to one of a fixed set of outcomes ("own-name", "held", "yielded", "kept", "superseded", "pre-decided"), and that outcome decides whether the name is recorded as user-chosen, auto-generated or a collision, whether the session announces that it gave the name up, and whether the old name is kept for the session list. Part of the cross-session naming machinery, whose availability is set by remote config.
Evidence
pre-decided
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
