 """cc-ci recipe-report launcher — one-shot agent that runs /recipe-report after the weekly upgrade.
 
 The report agent's model is configured SEPARATELY from the upgrader (REPORT_BACKEND/REPORT_MODEL),
-but defaults to the same OpenCode subscription on glm-5.2 as the upgrader. The model default tracks
-the backend+tier (opencode+zen→opencode/glm-5.2, opencode+go→opencode-go/glm-5.2, claude→opus).
+but defaults to the same OpenCode subscription as the upgrader (now OpenCode GO — the only tier
+with a key on this host; ZEN models are dead here, see launch-upgrader.py). The model default tracks
+the backend+tier (opencode+go→opencode-go/glm-5.3-flash, opencode+zen→opencode/glm-5.2, claude→opus).
 
 Usage:
   launch-report.py start [DATE]   use-or-create the session; runs /recipe-report [DATE]
