 # Changelog
 
+## 2025-12-04 - 7.7.1 - fix(web_serviceworker)
+Standardize DeesComms message format in service worker backend
+
+- Add createMessage helper to generate consistent TypedRequest-shaped messages (includes messageId and correlation.id/phase).
+- Replace inline postMessage payloads with createMessage(...) calls across ServiceworkerBackend (status updates, new-version broadcasts, alerts, event pushes, metrics updates, resource-cached notifications).
+- Improves message consistency and enables easier correlation/tracing of DeesComms messages; behavior should remain backward-compatible.
+
 ## 2025-12-04 - 7.7.0 - feat(typedserver)
 Add SPA fallback support to TypedServer
