Summary
Performance
Measured against a copy of a real workspace database with 28,619 runtime events and 77.47 MB of payload JSON:
A real 32-way deepseek-flash-reader swarm spawned all 32 children. During the active swarm, renderer CDP latency was 28 ms median, 124 ms p95, and 166 ms max; the previous build reached 15.8 seconds. Main-process profiling no longer showed decodeStoredRuntimeEvent, scanToolLedger, or assertToolLedgerTransition as hotspots.
