+A server release contains the Go API, web interface, database migrations and the coupled
+SSH reverse-tunnel service. The GitHub Actions server workflow tests the server and
+publishes two images with the same version:
 
 ```text
 ghcr.io/benya9669/openwrt-rmm-server:0.8.0
 ghcr.io/benya9669/openwrt-rmm-server:latest
+ghcr.io/benya9669/openwrt-rmm-tunnel:0.8.0
+ghcr.io/benya9669/openwrt-rmm-tunnel:latest
 ```
 
+The tunnel remains a separate container for isolation, but shares the server release line
+because its SSH policy and port-forwarding behavior form part of the server-side protocol.
+Introduce independent `tunnel-v*` releases only if the tunnel later gains a separate API
+and lifecycle.
+
 Increment `MAJOR` for incompatible API or migration requirements, `MINOR` for compatible
 features, and `PATCH` for compatible fixes. Database backups remain mandatory before a
 production upgrade even when the release is marked compatible.
