ae7195c829 feat: implement evolution engine for self-improving strategies
Some checks failed
CI / test (pull_request) Has been cancelled
Details 
Complete Pillar 4 implementation with comprehensive testing and analysis.

Components:
- EvolutionOptimizer: Analyzes losing decisions from DecisionLogger,
  identifies failure patterns (time, market, action), and uses Gemini
  to generate improved strategies with auto-deployment capability
- ABTester: A/B testing framework with statistical significance testing
  (two-sample t-test), performance comparison, and deployment criteria
  (>60% win rate, >20 trades minimum)
- PerformanceTracker: Tracks strategy win rates, monitors improvement
  trends over time, generates comprehensive dashboards with daily/weekly
  metrics and trend analysis

Key Features:
- Uses DecisionLogger.get_losing_decisions() for failure identification
- Pattern analysis: market distribution, action types, time-of-day patterns
- Gemini integration for AI-powered strategy generation
- Statistical validation using scipy.stats.ttest_ind
- Sharpe ratio calculation for risk-adjusted returns
- Auto-deploy strategies meeting 60% win rate threshold
- Performance dashboard with JSON export capability

Testing:
- 24 comprehensive tests covering all evolution components
- 90% coverage of evolution module (304 lines, 31 missed)
- Integration tests for full evolution pipeline
- All 105 project tests passing with 72% overall coverage

Dependencies:
- Added scipy>=1.11,<2 for statistical analysis

Closes #19

e025136047 Fix Docker runtime errors: migrate to google-genai SDK and fix SQLite permissions
Some checks failed
CI / test (push) Has been cancelled
Details 
Migrate from deprecated google-generativeai to google-genai (>=1.0) using the
new Client-based API, and fix SQLite "unable to open database file" in Docker
by chowning the data directory to appuser before switching users.

d1750af80f Add complete Ouroboros trading system with TDD test suite
Some checks failed
CI / test (push) Has been cancelled
Details 
Implement the full autonomous trading agent architecture:
- KIS broker with async API, token refresh, leaky bucket rate limiter, and hash key signing
- Gemini-powered decision engine with JSON parsing and confidence threshold enforcement
- Risk manager with circuit breaker (-3% P&L) and fat finger protection (30% cap)
- Evolution engine for self-improving strategy generation via failure analysis
- 35 passing tests written TDD-first covering risk, broker, and brain modules
- CI/CD pipeline, Docker multi-stage build, and AI agent context docs
