+## Development
+
+`main` is protected: no direct pushes. `develop` is the integration branch and is also protected. Work on a feature branch, open a PR into `develop`, then PR `develop` → `main` after CI is green.
+
+Workflow: `.gitea/workflows/validate.yml` (runs on PRs to `develop` and `main`)
+
+- YAML parse + `config.yaml` version vs `VERSION`
+- `emby-mcp`: `gofmt`, `go vet`, `go build`, `go test`
+- `openai-codex-proxy`: `node --check` on the entrypoint
+- `n95-mqtt-bridge`: upstream pin check + `go test` on the tagged upstream
+
+A Gitea runner labelled `ubuntu-latest` must be registered for those jobs to run.
