libtmux:kill-server

Terminate CLIENT's preflight-accepted daemon and return a COMMAND-OUTCOME. Success requires both a pre-dispatch receipt and observed exit of the server process accepted during this call. Missing evidence signals OUTCOME-UNKNOWN; cancellation or a deadline never causes an automatic retry. The connection CLIENT stays open but its generation is invalidated after observed server death. A failed exit wait retains :SERVER-EXIT-UNOBSERVED and the underlying ERROR-CAUSE. CLOSE-CLIENT never calls this function.
