+## Viewing logs
+
+To see verbose logs:
+1) Enable: Settings → search “Copilot Bridge” → enable “bridge.verbose”
+2) Open: View → Output → select “Copilot Bridge” in the dropdown
+3) Trigger a request (e.g., curl /v1/chat/completions). You’ll see:
+   - HTTP request lines (method/path)
+   - Access acquisition attempts (“Copilot access missing; attempting to acquire…”, “Copilot access acquired.”)
+   - SSE lifecycle (“SSE start …”, “SSE end …”)
+   - Health checks (best-effort access check when verbose is on)
 - bridge.verbose (boolean; default false): verbose logs to “Copilot Bridge” output channel
