 ## Workflows

\ No newline at end of file
+- **Gitea Actions**: `.gitea/workflows/build-v3-rpms.yml`
+
+Each build workflow now finishes with a repository assembly job that collects the shard artifacts,
+generates `repodata/` with `createrepo_c`, and uploads a ready-to-serve DNF repository artifact.
+
+## Repository artifacts
+- **GitHub Actions** uploads `dnf-repo-x86-64-v3`
+- **Gitea Actions** uploads `dnf-repo-x86-64-v3` and `dnf-repo-x86-64-v4`
+
+Each repository artifact contains:
+- `packages/` with the built binary RPMs
+- `repodata/` generated for DNF
+- a `.repo` template with a placeholder `baseurl`
+- `README.txt` with Fedora 43 install instructions
