wesandClaude Fable 5 b97401fec8 canbus: reverse-engineer OneControl IDS-CAN bus (read fully mapped, write auth-gated)

Tapped the X180T's CAN bus via CANable 2.0 at the monitor panel's terminator
port. The bus is NOT RV-C — it's Lippert's proprietary IDS-CAN (250k, 11-bit
IDs, (page<<8)|node, 1 Hz broadcasts).

Read side fully mapped from live captures:
- device classes (page-2 type byte: 0x0A tank, 0x1E switched load, 0x21 motor)
- node map for this rig (Catalina 263BHSCK): tanks 27/E2/7D/FE, lights 2A/F8,
  heater 95, pump 61, awning 75 (+ direction & live motor current)
- battery voltage on 29-bit extended frames

Write side: commands are DLC-0 ext frames 0006<node><op>, but auth-gated by a
rolling challenge-response (page 42/43). Replay confirmed dead (spoofed cansend
did not actuate). Not the BLE TEA cypher. response=f(challenge) is deterministic
(no session state) so crackable offline later — seeded 42 pairs in
sniff/2A-auth-pairs.txt.

Includes raw captures (sniff/*.log, force-added past *.log ignore), a read-only
esp32_can ESPHome skeleton, and the log-can.sh sniff helper. Full writeup in
canbus/README.md.
