+## Code Health
+
+- **Rebuild the compiled CLN channels controller to match its source**
+  ([#1631](https://github.com/Ride-The-Lightning/RTL/pull/1631)).
+  The #1606 fix updated `server/controllers/cln/channels.ts` to mirror `peer_connected` onto the
+  legacy `connected` field, but the committed compiled artifact
+  `backend/controllers/cln/channels.js` was never regenerated, so it lagged its source. Rebuilt it
+  so the committed backend output includes the connected-mirror line.

 ## Developer Tooling
 
 - **Rebuilt the regtest docker fixture**
