Navigation: self-hosted MapLibre + Valhalla + PMTiles, offline-first, with Japan specifics (left-hand traffic via valhalla_build_admins, data volume, CJK labels). Map matching pulled forward as Phase 2 ground truth. Orin runtime: new document covering the 8 GB shared-memory budget, capture-first startup tiers, failure isolation, storage and the audio graph. Data flow: direction belongs to topics inside the Orin; the display boundary is two simplex channels rather than one duplex socket; cloud links are outbound-initiated only; services mock themselves rather than having separate stub implementations. Naming: repositories are <group>-<thing> with no project prefix, so lexical order matches semantic grouping. Indexes the five new repos. Decisions 8-19 recorded; 14 (recording retention) left open.

# Project Yukart
|
|
|
|
Making a 2008 Mitsubishi Colt Ralliart (Z27AG) a bit smarter with modern technologies.
|
|
What the system is meant to do is described in [OVERVIEW.md](OVERVIEW.md).
|
|
|
|
This repository is the **overview and roadmap only — it holds no code.**
|
|
Every application or application cluster lives in its own repository and is
|
|
indexed here.
|
|
|
|
## Documents
|
|
|
|
- [Overview](OVERVIEW.md) — what the system is meant to do
|
|
- [Architecture](docs/ARCHITECTURE.md) — system shape, services, message bus, display contract
|
|
- [Orin runtime](docs/ORIN-RUNTIME.md) — what runs on the board: memory budget, startup tiers, audio
|
|
- [Repositories](docs/REPOS.md) — repo layout, naming, template-repo policy
|
|
- [Roadmap](docs/ROADMAP.md) — phases and current status
