- Add vbt_backtest.py as single source of truth for all metric formulas
(Sharpe, drawdown, IC, transaction costs) — backtest_engine.py and
strategy_orchestrator.py now delegate to it
- Add LLMUnavailableError to exception.py; rd_loop.py catches it at the
proposal stage and raises LoopResumeError to avoid corrupting trace
history with None hypotheses
- Guard record() against None exp/hypothesis so loop resets leave
trace.hist in a consistent state
- Refactor strategy_orchestrator and optuna_optimizer to use unified
backtest path; remove duplicate metric calculation code
- Add predix_rebacktest_unified.py script for offline re-evaluation
- Update tests and README

Implement automatic trading protection system to prevent excessive losses:
PROTECTIONS (100% original code, NOT copied from Freqtrade):
- Max Drawdown Protection: Blocks trading when DD > 15% (configurable)
- Cooldown Period: 4h mandatory rest after 5% loss
- Stoploss Guard: Detects stoploss clusters (>5 per day)
- Low Performance Filter: Filters factors with Sharpe < 0.5, Win Rate < 40%
ARCHITECTURE:
- Base protection interface with common utilities
- 4 specialized protection implementations
- ProtectionManager orchestrates all active protections
- Time-based blocking with automatic expiry
TESTS (32 total, ALL PASS):
- 25 unit tests in test/backtesting/test_protections.py
- 7 integration tests in test/integration/test_all_features.py
- Tests cover: normal operation, edge cases, error handling
DOCUMENTATION:
- Update QWEN.md with development guidelines for AI assistant
* Mandatory rules: Update QWEN.md, README, requirements.txt, tests
* Pre-commit checklist
* Example workflow
- Update README.md with protection system features
- Update project structure with new modules
