The auditor's role is 'silent observer' — read every channel and emit
a reflect note when something notable happens. Smoke run 3 never
spawned auditor because no event-subscription registered it. Added
handler handle_auditor_spawn() wired to:
- task.blocked (EventType.TASK_BLOCKED)
- task.cancelled (EventType.TASK_CANCELLED)
- task.awaiting_ceo_approval (EventType.TASK_AWAITING_CEO_APPROVAL)
Routine events (task.claimed, task.started, task.created) deliberately
do NOT trigger auditor — those are progress, not exceptions. The
auditor's container is one-shot: i_am_idle() exits after logging its
reflect note.
Auditor spawn failures are swallowed into a WARNING log so they cannot
block the underlying event's processing chain. The auditor is a silent
observer — its absence must have no side effects on the lifecycle.
