# Changelog
## 2025-12-04 - 6.1.0 - feat(web_serviceworker)
Enhance service worker subsystem: add metrics, event bus, error handling, config and caching/update improvements; make client connection & polling robust
- Introduce MetricsCollector (cache, network, update, connection) for runtime observability and APIs to retrieve metrics
- Add EventBus singleton to emit/subscribe to internal SW events (cache hits/misses, network events, update lifecycle, connection events)
- Add ErrorHandler and ServiceWorkerError types for consistent error classification and tracking
- Add ServiceWorkerConfig with defaults and WebStore persistence to centralize SW settings (cache, update, network, blocked/cacheable domains)
- CacheManager: implement request deduplication (in-flight request coalescing), periodic in-flight cleanup, record cache hit/miss metrics and safer cache storing (headers/body handling)
- UpdateManager: rate-limited and concurrency-safe update checks, improved stale-cache handling, event emissions, debounced update and revalidation tasks, and metrics recording
- NetworkManager: enhanced online/offline detection and robust request retries/timeouts/backoff handling
- ServiceworkerBackend: improved client reload logic and notification handling via DeesComms and clients API
- Serviceworker client-side: ActionManager.waitForServiceWorkerConnection now returns a structured result with timeout/retries/backoff; ServiceworkerClient gains controllable polling (AbortController), visibility-based pause/resume, manual trigger and lifecycle cleanup
- Expose serviceworker bundle routes at both nested and root paths (/serviceworker/*splat and /serviceworker.bundle.js(.map)) in servertools
- Add/extend typed interfaces for serviceworker metrics and connection results
## 2025-12-04 - 6.0.1 - fix(web_inject)
Use TypedSocket status API in web_inject and bump dependencies
