fix: Reduce coordinator chunk_size from 10k to 2k for small explorations
...
- 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

feat: Continuous optimization cluster for 2 EPYC servers
...
- Master controller with job queue and result aggregation
- Worker scripts for parallel backtesting (22 workers per server)
- SQLite database for strategy ranking and performance tracking
- File-based job queue (simple, robust, survives crashes)
- Auto-setup script for both EPYC servers
- Status dashboard for monitoring progress
- Comprehensive deployment guide
Architecture:
- Master: Job generation, worker coordination, result collection
- Worker 1 (pve-nu-monitor01): AMD EPYC 7282, 22 parallel jobs
- Worker 2 (srv-bd-host01): AMD EPYC 7302, 22 parallel jobs
- Total capacity: ~49,000 backtests/day (44 cores @ 70%)
Initial focus: v9 parameter refinement (27 configurations)
Target: Find strategies >00/1k P&L (current baseline 92/1k)
