Nothing public decodes the Z27 Colt's broadcast frames; MUT-III diagnostic
requests are covered by OBDb's open Mitsubishi signal set. The first capture
gives engine-speed candidates in 0x210 and 0x13D, to confirm against OBD-II.

What crosses between svc-gw and the app: hello, heartbeats both ways, state
snapshots of envelopes with mock flagged per message, and commands carrying an
idempotency key. TTS utterances are left for when a TTS exists.

The app<->svc-gw channels have no wire format yet. Measured USB link
drops (~3 s per power change, sleeping tablet invisible at link level)
and yukart decision 24 already fix the required fields: heartbeat,
command idempotency key, and utterance id/sequence/terminator/expiry.
