mikkeli b55ccba268 Define display boundary protocol v0
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.

Part of Project Yukart, making an old 2008 Mitsubishi Z27AG a bit smarter with modern technologies.
This file serves as the minimalist portal to other docs

What this repo is about

The topic namespace, payload schemas and signal registry that every other repo depends on. Rust services, Python tooling and the Dart client all read the same definitions from here.

File Holds
schema/topics.json Topic namespace: payload kind, retention, rate, publisher
schema/envelope.json JSON Schema for the decoded-signal envelope
schema/signals.json Signal registry — the single source for name, unit, type and range
docs/BOUNDARY.md Display boundary protocol: what crosses between svc-gw and the app

The Z27AG DBC lands here too, once Phase 2 produces one.
