+# Implementation Spec: Round 4
+
+## Status: COMPLETE
+
+## New Features
+
+### 1. CircuitBreakerMetrics (circuit_breaker.rs)
+- Added `CircuitSnapshot { state: CircuitState, failures: u64, successes: u64 }` struct
+- Added `CircuitBreaker::snapshot() -> CircuitSnapshot` method (atomic load)
+- Test: `snapshot_reflects_state_and_counts`
+
+### 2. RetryStats (retry.rs)
+- Added `RetryStats { attempts: u32, retries: u32, last_error: Option<String> }`
+- Added `retry_with_stats()` returning `(Result, RetryStats)` (parallel to retry())
+- Tests: 2 new
+
+### 3. AsyncLifecycleManager (lifecycle.rs) — Round 3 carryover, verified
+- Composes ShutdownManager + HealthRegistry + health loop
+- Tests: 3
+
+### 4. MetricsBridge (metrics_bridge.rs) — Round 3 carryover
+- `MetricsBridge` emits MetricsCollector → tracing
+- `MetricsHealthCheck` wraps collector as HealthCheck
+- Tests: 2
+
+## Fixes in round 4
+- `HealthRegistry` wrapped in `Arc` in AsyncLifecycleManager (not Clone)
+- Removed unused `span`/`Instrument` import in lifecycle.rs
+- Fixed `op_ref` mutability in service_builder.rs
+- Fixed `last_error` assertion (None on success) in retry test
+- Fixed snapshot test assertions (successes not incremented in Closed state)
+
+## Build Status
+- cargo build --workspace --all-features: OK (2 pre-existing warnings in crypto/cli)
+- cargo test --workspace --all-features: ALL PASS
+- cargo clippy: 0 warnings on round-4 code (pre-existing in crypto/cli only)
+- Committed + pushed
