## New Features
### 1. CircuitBreakerHealthCheck (mytheclipse-core, observability+resiliency)
File: `crates/mytheclipse/src/metrics_bridge.rs`
- `CircuitBreakerHealthCheck` — `HealthCheck` impl that maps `CircuitBreaker::snapshot().state` to HealthStatus:
- Open → Unhealthy
- HalfOpen → Degraded
- Closed → Ok
- Gated `#[cfg(feature = "resiliency")]`; re-exported when both observability+resiliency enabled
- Feature interaction: `observability` now implies `lifecycle` (needed for `crate::health::{HealthCheck, HealthStatus}`)
- `CircuitBreakerHealthCheck` di metrics_bridge.rs — HealthCheck impl yang memetakan CircuitBreaker snapshot state → HealthStatus (Open→Unhealthy, HalfOpen→Degraded, Closed→Ok)
- Gated `#[cfg(feature="resiliency")]`; re-export gated `#[cfg(all(observability, resiliency))]`
- `observability` feature now implies `lifecycle` (needed for crate::health module access)
### 2. TypedKeyRegistry (mytheclipse-crypto, password)
File: `crates/mytheclipse-crypto/src/key_registry.rs`
- `TypedKeyRegistry<K, V>` — registry keyed by string ID, wraps KeyRing for current/previous rotation
- `key_for(&self, id: &str) -> Option<&K>` typed lookup
- `rotate_with_id(&mut self, id, key)` + `revoke(id)`
- Default impl uses String keys (v4 signers)
- `TypedKeyRegistry<K,V>` di key_registry.rs — ID-based key lookup + rotation + revoke, wraps KeyRing
- `key_for(id) -> Option<&K>`, `rotate_with_id(id, key)`, `revoke(id)`
### 3. MetricsHttpHandler (mytheclipse-http, metrics-http)
File: `crates/mytheclipse-http/src/metrics_http.rs`
- new feature `metrics-http` (axum + tower + mytheclipse/observability)
- `metrics_routes(collector) -> Router` serving `/metrics` (Prometheus text via `export_prometheus`) + `/`
- `tower` dep added (util feature)
- `metrics_routes(collector)` → Router serving /metrics (Prometheus text) + /
- added tower dep (util), ServiceExt import in test module
- 1 test via ServiceExt::oneshot
### 4. BatchProcessor (mytheclipse-queue, in-memory)
- `BatchJobHandler` trait — handle Vec<Job> atomically
- `BatchConfig` { batch_size, batch_timeout, concurrency }
- `BatchProcessor<Q>` — accumulates jobs per topic, flushes on size/timeout
- 2 tests: flush_on_batch_size, flush_on_timeout
## Verification
- `cargo build --workspace --all-features` → exit 0
- `cargo test --workspace --all-features` → all pass (160+ tests)
- `cargo clippy --workspace --all-features` → no new warnings
- cargo build --workspace --all-features → exit 0
- cargo test --workspace --all-features → all pass (160+ tests)
- cargo clippy --workspace --all-features → no new warnings
