A ready check's start line took the leader's name from the party roster, so it printed even when the client did not know the name, with an empty name if the roster lacked the leader.
**Reference:** the handler asks the name cache with no callback (`0x4ba50f` → `0x55f080`). A miss returns at once without a query (`0x55f120`-`0x55f125`, `0x55f221`), and the line is skipped (`0x4ba514`-`0x4ba516`). The deadline and READY_CHECK follow either way (`0x4ba535`, `0x4ba53a`).
**Changed:** the line reads the leader through the name cache, as the leave line does (#2000), and a miss prints nothing and sends nothing.
**Tests:** a cached leader prints the line before the popup, and an uncached one prints none and sends no query, while READY_CHECK still fires.
Fixes#2792.
