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.
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 — what the system is meant to do
- Architecture — system shape, services, message bus, display contract
- Orin runtime — what runs on the board: memory budget, startup tiers, audio
- Repositories — repo layout, naming, template-repo policy
- Roadmap — phases and current status
