Function derivePhaseStatus

src/workflow/panel/selectors.ts:32–41

* Derive a phase's sidebar status from the actual record + the agents grouped under it. * * The actual record comes from `phase_started`/`phase_done` events. Scripts that follow the * ultracode canonical pipeline pattern pass `opts.phase` directly to `agent()` inside * `pipeline()`/`parallel()`

(
  actual: { status: 'running' | 'done' } | undefined,
  inPhase: AgentProgress[],
)

 *    (`running` if `phase()` was called and is still active, else pending).
