 ### Fixes
 
+- Gateway/Agents: stop injecting a phantom `main` agent into gateway agent listings when `agents.list` explicitly excludes it. (#11450) Thanks @arosstale.
 - Agents/Heartbeat: stop auto-creating `HEARTBEAT.md` during workspace bootstrap so missing files continue to run heartbeat as documented. (#11766) Thanks @shadril238.
 - Telegram: cap bot menu registration to Telegram's 100-command limit with an overflow warning while keeping typed hidden commands available. (#15844) Thanks @battman21.
 - CLI: lazily load outbound provider dependencies and remove forced success-path exits so commands terminate naturally without killing intentional long-running foreground actions. (#12906) Thanks @DrCrinkle.
