OpenAI Codex automation prepared and validated this follow-up. The submitted plugin fails four new setter-order regression scenarios; all 12 revised host scenarios pass with ASan/UBSan. Both complete climate-A ESP8266/ESP32 firmware builds pass, retaining existing warnings in unchanged sources. No physical ESP board or HDC10xx sensor was tested.
