libtmux:list-server-access

Print the daemon ACL; return owned UTF-8 text and a COMMAND-OUTCOME. The ordinary native listing preserves escaping and whitespace. Before 3.8, rows use (R)/(W); from 3.8 they include U/G account kinds. UID 0 is omitted and unresolvable names print as unknown. An empty listing does not prove that no account has access. This is printer output, not a decoded authorization model. Blocks under shared preflight/dispatch limits and never retries or acquires an observation. Invalid UTF-8 signals DECODING-ERROR; native and operational failures retain their outcomes.
