@@ -76,3 +76,16 @@ For manifest mode, the Agent fetches:
 ```
 
 Docker image components require Docker Engine on the client machine. By default `AUTO_INSTALL_DOCKER=true`, so the agent will install the trusted distro package `docker.io` with `apt-get` when a Docker app is installed and Docker is missing. Set `AUTO_INSTALL_DOCKER=false` if Docker must be provisioned by your own fleet policy. The agent validates `image` against `ALLOWED_DOCKER_REGISTRIES`, then runs a managed container using the manifest fields `containerName`, `restartPolicy`, `ports`, `volumes`, and `env`.
+
+APT components use a fixed manifest contract and never accept shell commands:
+
+```json
+{
+  "componentId": "postgresql",
+  "type": "apt",
+  "packageName": "postgresql",
+  "version": "16"
+}
+```
+
+The package name must be present in `ALLOWED_APT_PACKAGES` (default: `postgresql`). For PostgreSQL, the Agent refreshes the APT index, installs the distro package non-interactively, verifies `postgresql.service`, and waits for `pg_isready` before completing the task.
