 The workflow will download the artifact, resolve any `{arch}`, `{app-id}`, or `{branch}` placeholders in the name, and find the matching `.flatpak` bundle inside it. If the downloaded artifact contains multiple `.flatpak` files, the workflow will use `flatpak info --show-ref` to automatically identify and select the one matching the current matrix cell's `app-id` and `arch`.
 
+### Ingesting local pre-built bundles in the reusable workflow
+
+If you have prebuilt `.flatpak` bundle files locally in the checked-out repository (or built in a previous job on a self-hosted runner where the workspace is shared), you can pass them directly using the `bundle-path` input. The reusable workflow will publish them in a single job without compiling or running a matrix:
