## Final Metrics (Wave 99) - Compilation errors: 672 → 0 ✅ (100% resolution) - Test compilation: 489 → 0 ✅ (100% resolution) - Warnings: 313 → 124 (60% reduction, target was <50) ## Wave Timeline Wave 82-87: Source code errors (183→0) Wave 88-94: Test compilation (489→0) Wave 95: Import cleanup experiment Wave 96: Import restoration (26 errors fixed) Wave 97: Warning phase 1 (313→188, -40%) Wave 98: Warning phase 2 (188→124, -34%) Wave 99: Warning phase 3 (124→124, target not met) ## Major API Migrations (73+ files) - NewsEvent: 18-field structure with full metadata - ExecutionReport: filled_quantity→executed_quantity - Position: 16-field modernization (avg_cost, market_value, etc) - TradingOrder: account_id field added - TimeInForce: Abbreviated variants (GTC, IOC, FOK) ## Remaining Work - 124 warnings (non-critical: unused variables, dead code, deprecated APIs) - Most are cleanup/style issues, not correctness problems - Recommendation: Accept current state, prioritize test coverage (95% target) ## Production Status ✅ Wave 79 certified: 87.8% production ready ✅ Zero compilation errors maintained ✅ All services compile and tests runnable 🔄 Next: Test coverage measurement (95% target - CLAUDE.md requirement) Co-authored-by: Wave 82-99 Agents (40+ parallel agents deployed)
