 * Pipeline state tracking completion histories for all phases.

 * Each phase stores its latest and previous execution history. The step counter
 * pattern enables automatic dependency tracking: when a phase reruns, its step
 * increments and downstream phases become invalid through step mismatch.
 *
 * State is reconstructed from event history. `null` means the phase hasn't
 * completed yet.
