# Core services

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 acquisition and processing cluster on the Orin, developed and deployed as one
unit: `recorder` now; `can-bridge`, `obd-poller`, `gnss` and `decoder` as they are
needed.

| Binary | Installed as | Does |
|---|---|---|
| `recorder` | `yukart-recorder.service` | Raw CAN + GNSS to disk, in sessions, under a storage bound |

```bash
scripts/deploy-recorder.sh                 # build, glibc check, install on the car Orin
yukart-recorder ctl status                 # on the Orin
yukart-recorder ctl start "cold start"     # manual session, ends only on stop
yukart-recorder ctl mark "indicator left on"
yukart-recorder ctl stop
```

Recordings live in `/var/lib/yukart/recordings/`, one directory per session —
layout in [the initial plan](docs/impl/plans/INITIAL.md#session-layout).
