+### Quick Reference
+- Every PR must link to at least one issue
+- Use Gitea MCP tools for issue/label/branch/PR operations
+- Labels: `status/backlog` -> `status/ready` -> `status/in-progress` -> `status/review` -> `status/done`
+- Branches: `issue-{index}-{slug}` (e.g., `issue-42-add-fuel-report`)
+- Commits: `{type}: {summary} (refs #{index})` (e.g., `feat: add fuel report (refs #42)`)
