 `.forgejo/workflows/ci.yaml` is Crafter.Build's workflow for this app.
 - **Builds.** A pull request builds the Flatpak, runs the suite inside it and smoke-tests the app as it ships: the version and home, every library resolved and no RUNPATH outside `/app`, the bundled tools, and a freeze and a dry run on a scratch repository.
 - **Publishing.** Every push to master is a release (2026-11-02, Jorijn: no rolling `beta` or `latest` builds): CI publishes `stable`, tags the pushed commit with the version of the metainfo's newest `<release>` and creates the release with its notes. A push to master therefore adds a new `<release>`; one whose version is released already fails the job before anything is built or published.
-- **The runner.** It runs on the `crafter-flatpak` runner, registered to Crafter.Build alone today: until this repository has such a runner, the workflow does not run, and it is unverified on the forge. Its smoke test passes when run by hand against a local build.
+- **The runner.** It runs on the Catcrafts organisation's privileged `flatpak` runner, in two jobs by trust, as imsd-messages' workflow does: `check` (a pull request, a run by hand on another branch) builds cold with no host volume; `publish` (master) mounts the crafter-build installation the publish jobs share (`crafter-flatpak-org-system`), the published repository and its signing key. flatpak-builder's state stays in the workspace, so every run builds cold. The workflow is unverified on the forge until its first run; its smoke test passes when run by hand against a local build.
 - **The shared repo.** Both apps publish into one repo. The publish step holds `/srv/flatpak/.publish.lock`, which protects anything only once Crafter.Build's workflow takes the same lock. This one writes its own flatpakref and never the shared `catcrafts.flatpakrepo`.
