Test / test (push) Failing after 25m47s
Go port of the read path of pybyd 0.0.75 (the client behind jkaberg/hass-byd-vehicle): the bangcle white-box AES envelope, the signing/checkcode layer, login, vehicle list, and realtime readings. Scraping runs on a cron schedule rather than per Prometheus request because each reading wakes the car's T-Box and drains the traction battery; /metrics serves the last result. Every numeric field of the realtime payload becomes a gauge, so the exporter does not need a hand-maintained field list that goes stale when BYD changes the payload. Tests pin the wire format against pybyd byte-for-byte and drive the client end to end against a fake cloud that speaks the real protocol. Co-Authored-By: Claude Opus 5 <[email protected]>
