Command path proven end to end on the bus (node F8 interior lights, on/off/on),
each answering a distinct fresh challenge; bare opcodes without the exchange are
ignored. ids_can_auth.h verified bit-exact against ids_can_auth.py and the
captured/live pairs.
- idscan_cmd.py: stdlib socketcan tool running the full page-42/43 exchange
- esphome/onecontrol-canbus.yaml: correct IDS-CAN read dispatch (was stale RV-C
DGN code) + command path wired to the auth header
- README/memory: document the read map + command authentication; rename
sniff/ -> captures/; neutral device-integration framing throughout
