```
(outcome-phase outcome)

Primary method: libtmux:command-outcome:
(outcome-phase (command-outcome libtmux:command-outcome))
```

Return retained dispatch evidence, without I/O.
Raw process phases are :PREPARED, :LAUNCHING, :DISPATCHED and :EXITED. Named
operations may also report :PREFLIGHT or :GUARD-REJECTED before payload dispatch.
Explicit server termination reports :SERVER-TERMINATED only after retained
pidfd readiness proves exit. Phase is separate from OUTCOME-STATUS; an exited
queue can have partially completed effects even when it reported failure.
