🚀 Wave 127 Wave 2: Execution Validation (6 agents)

**Mission**: Validate frameworks created in Wave 126

**Agent 120b: Prometheus Exporters Fix** ⚠️ Code Complete
- Fixed all 4 services (wrong Prometheus registries)
- API Gateway: Now uses GatewayMetrics registry
- Trading Service: Uses TradingMetricsServer
- Backtesting/ML: Created simple_metrics modules
- Built successfully (1m 51s)
- BLOCKER: Docker rebuild needed for deployment

**Agent 122: E2E Test Execution** ❌ BLOCKED
- Fixed Tonic 0.12 → 0.14 migration (all proto enums)
- 54 E2E tests compile successfully
- BLOCKER: JWT auth not implemented in test framework
- Impact: 0/54 tests can execute

**Agent 123: Load Test Execution** ❌ BLOCKED
- Framework validated (7,960-9,354 req/sec client-side)
- HDR histogram metrics working
- BLOCKER: SQL schema mismatch (price vs limit_price)
- Impact: 100% failure rate (477K attempted, 0 successful)

**Agent 124: Benchmark Execution** ✅ PARTIAL
- Authentication: 4.4μs ✅ (<10μs target)
- Order matching: 1-6μs P99 ✅ (<50μs target)
- Component latencies validated
- Gap: E2E, risk, ML benchmarks not executed

**Agent 125: PPO Test Fix** ✅ COMPLETE
- Test already passing (575/575 ML tests)
- 100% pass rate in ML crate
- No fix needed (transient failure)

**Agent 126: Security Hardening** ✅ COMPLETE
- RSA 4096-bit certificates generated and deployed
- All services restarted successfully
- H1 security gap closed

**Wave 2 Results**:
- Achievements: Component latency validated, security hardened, GPU working
- Critical Blockers: 3 identified (E2E auth, load test SQL, Prometheus deployment)
- Production Readiness: 91-92% (unchanged - blockers prevent further validation)

**Files Modified** (21):
- services/integration_tests/* (6 files - E2E test compilation fixes)
- services/*/src/main.rs (3 files - Prometheus exporters)
- services/backtesting_service/src/simple_metrics.rs (new)
- services/ml_training_service/src/simple_metrics.rs (new)
- certs/production/* (RSA 4096-bit certificates)
- services/load_tests/tests/* (relocated)

**Critical Blockers Identified**:
1. E2E: JWT Interceptor missing (2-4h fix)
2. Load: SQL schema mismatch (1-2h fix)
3. Prometheus: Docker rebuild needed (30m)

**Validation Report**: /tmp/wave2_gate_validation.md

**Next**: Deploy 3 blocker-fix agents, then Wave 3
