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 becomes the code-free hub: overview, roadmap and cross-cutting
design only. Each app or app cluster gets its own repo, indexed from here.
- ARCHITECTURE.md: separate services over a message bus, with displays as bus
subscribers so the directly-driven screen, Android client and ESP32 panel
share one contract. Records CAN scope (listen-only + OBD-II as sole writer)
and a decisions table for choices still in flux.
- REPOS.md: repo splitting rule, planned repos, naming, and Gitea template-repo
policy (scaffolding only — no upstream link after instantiation).
- ROADMAP.md: phases 0-5, capture and decode before displays.
Bus choice (MQTT) is marked proposed pending a check against real CAN rates;
implementation language is still open.
