Auto-spawned discuss/plan/refine agents were invisible because: 1. listInitiatives only filtered for mode='detail' agents 2. deriveInitiativeActivity returned 'idle' for zero phases before checking for active agents Broadened agent filter to all architect modes (discuss, plan, detail, refine), moved active agent check before zero-phases early return, and added 'discussing'/'refining' activity states with pulsing indicators.
