# Brave Sync Server v2 Rust Port

Rust port of the Brave Sync v2 command server from `/home/user/go-sync`.

The server exposes:

- `GET /`
- `GET /health-check`
- `POST /v2/command/`
- `GET /metrics`

## Storage

This port uses SQLite instead of DynamoDB. On startup it creates the required
tables automatically.

Environment variables:

- `SQLITE_PATH`: SQLite database path. Defaults to `brave-sync.sqlite3`.
- `LISTEN_ADDR`: HTTP listen address. Defaults to `0.0.0.0:8295`.
- `BLOCKED_CLIENT_IDS`: comma-separated lowercase or uppercase client public key hex values.
- `HIGH_DEVICE_LIMIT_CLIENT_IDS`: comma-separated client IDs allowed up to 100 active devices.

## Build and Test

```sh
cargo test
cargo run
```

## Docker

```sh
docker build -t brave-sync-rs .
docker run --rm -p 8295:8295 -v brave-sync-data:/var/lib/brave-sync brave-sync-rs
```

For bind mounts, the container starts as root only long enough to create/chown
the SQLite directory, then runs the server as the `brave-sync` user.

The protobuf Rust bindings are generated at build time from
`schema/protobuf/sync_pb`. A vendored `protoc` binary is used, so a system
`protoc` install is not required.
