+- **Base image**: `node:24` — Debian-based Node.js image (not Alpine, needed for apt packages).
-- **Install**: `npm i -g opencode-ai` — installs OpenCode globally.
+- **Install**: `npm i -g opencode-ai n2-soul@<version>` — installs OpenCode and Soul globally.
 - **Version check**: `RUN opencode --version` after install to validate the build and record the installed version in build logs.
-- **Dedicated user**: a non-root `opencode` user and group are created with `addgroup`/`adduser`. All runtime steps run as this user.
+- **Dedicated user**: a non-root `opencode` user and group are created with `groupadd`/`useradd` (UID/GID 1000). All runtime steps run as this user.
-- **Entrypoint**: `["opencode", "serve"]` — the container always starts the HTTP server.
+- **Cluster tooling**: `kubectl` is copied from the official `registry.k8s.io/kubectl` image (multi-stage COPY).
+- **Entrypoint**: `["opencode"]` — arguments are passed at runtime (e.g. `serve`).
