Enum HookSignal 

pub enum HookSignal {
    Running,
    NeedsInput,
    Interrupted,
    TurnFinished,
}

One coarse lifecycle signal. This is the COMPLETE vocabulary the lane can express — deliberately much smaller than mission status, so no hook payload can ever spell a state transition (FeatureFailed, Blocked, Complete, grant mutations): the mapping is an enum, not a string.

Variants

Running

The session is alive and working (sessionStart).

NeedsInput

The session appears to want operator attention (cursor: a headless tool call was refused by the permission posture — postToolUseFailure with failure_type == "permission_denied").

Interrupted

The session ended abnormally (sessionEnd with aborted/error/window_close/user_close).

TurnFinished

The session finished its turn (stop, or sessionEnd with completed).
