- spawn-ledger: Spawn log (spawn_start/launched/end + cost, native agentId lineage), artifact check and in-session RESPAWN_REQUEST picku (Review before installing)
- voice-compact: Startup token diet: rewrites the long CAVEMAN / PONYTAIL MODE ACTIVE hook-context injections into ~150-token compact rul (Low risk)
