- Changed default chunk_size from 10,000 to 2,000
- Fixes bug where coordinator exited immediately for 4,096 combo exploration
- Coordinator was calculating: chunk 1 starts at 10,000 > 4,096 total = 'all done'
- Now creates 2-3 appropriately-sized chunks for distribution
- Verified: Workers now start and process assigned chunks
- Status: ✅ Docker rebuilt and deployed to port 3001
