Definitions built from an exhaustive B5 09 register scan of a real appliance (1280 addresses probed on pages 00-04; 555 answered, 215 of them covered by known message definitions). Until now this product id fell through to the final bai.308523.inc fallback, which polls 29 registers this appliance does not have and misses its CO-sensor diagnostics. Five CO-sensor registers on page 01 reply with the value followed by its bitwise-negated copy (integrity check); modelled with a trailing ignored field. Verified against the live appliance (decoded values plausibility-checked, d.93 DSN readback matches the rating plate). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
