> Liveness/readiness and Prometheus metrics.

All routes on this page are **unauthenticated**.

```http theme={null}
GET /api/v1/healthz
```

Composite health probe. The endpoint returns `200 {"status":"ok"}` when healthy and `503` with a degradation
reason when WAL replay or a subsystem probe is unhealthy.

```http theme={null}
GET /api/v1/readyz
```

Traffic-readiness probe. The endpoint returns `503` only while WAL replay is in progress; object-storage
degradation does not make read-only traffic unready.

```http theme={null}
GET /api/v1/version
```

Returns product version, commit, branch, build epoch, and the raw `oss` or `enterprise` build
edition value. The product UI presents these as OpenSource Edition and Enterprise Edition.

```http theme={null}
GET /metrics
```

Prometheus exposition (`text/plain; version=0.0.4`) with process and subsystem metrics.
