Struct SupervisorState 

pub struct SupervisorState {
    pub supervisor_pid: Option<u32>,
    pub supervisor_alive: bool,
    pub sessions: Vec<SupervisedSession>,
    pub unmanaged_pids: Vec<u32>,
    pub stale_binary_sessions: Vec<String>,
}

Read-only snapshot of the supervisor’s current topology — supervisor liveness + per-session daemon liveness + orphan pids the supervisor is not currently managing. Used by wire supervisor (the CLI counterpart to single-session wire status) so operators can ask “what is the multi-session supervisor doing?” in one command instead of cross-referencing pgrep against per-session pidfiles by hand.

Fields

supervisor_pid: Option<u32>

Pid the supervisor.pid file names; None if file missing.

supervisor_alive: bool

True iff that pid is currently a live process.

sessions: Vec<SupervisedSession>

Per-session liveness across every initialized session, in list_sessions() order.

unmanaged_pids: Vec<u32>

wire daemon pids found via cmdline-scan that are NOT mapped to any session’s pidfile AND are not the supervisor itself. Could be legacy operator-spawned daemons, leftover children from a crashed prior supervisor, or daemons serving the default WIRE_HOME (no --all-sessions). Operators see them here so they can decide whether to kill.

stale_binary_sessions: Vec<String>

v0.14.2: session names whose live daemon’s recorded pidfile.version is older than this CLI’s own CARGO_PKG_VERSION. The supervisor’s existing-pidfile check skips alive daemons regardless of their binary version, so stale-binary daemons persist until they exit. Surfaced for operator visibility — they can pkill -TERM <pid> or use a future wire upgrade --refresh-stale-children to force the supervisor to respawn them on the current binary.
