# Lippert IDS-CAN command-auth challenge/response pairs — MULTI-NODE
# Captured 2026-06-11, app-driven (phone app issued on/off/move commands).
# Source log: app-commands-2026-06-11_230059.log  (node 2A bulk set lives in 2A-auth-pairs.txt).

# Exchange (controller node 01 <-> module node), all 29-bit extended frames:
#   id = (src<<18) | (dir<<16) | (dest<<8) | page    dir: 0 = 01->node, 1 = node->01
#   arm       01->node  page42  DLC2  "00 04"
#   challenge node->01  page42  DLC6  "00 04 <CC CC CC CC>"
#   response  01->node  page43  DLC6  "00 04 <RR RR RR RR>"
#   ack       node->01  page43  DLC2  "00 04"
# format below: <challenge_hex> <response_hex>  (the 4-byte payload tails)
#
# Confirmed: the SAME handshake gates every node tested — switched loads AND the
# awning (movement class). 51 pairs total across 4 nodes; response = f(challenge)
# is nonlinear (not GF(2)-affine, not Z/2^32-affine, full byte diffusion).

# node 61 — water pump (type 0x1E switched load)

# node 75 — awning (type 0x21 H-bridge/movement) — full nonce gate, same as loads

# node 2A — exterior lights (type 0x1E) — 2 extra pairs from this session;
# 42 more in 2A-auth-pairs.txt (extlight-authpairs-*.log). 21CA0C06 is the pair
# the README used to rule out the BLE TEA key.
