+- **Notes**: Metabase query failed with HTTP 401 Unauthenticated. `METABASE_API_KEY` is present in environment K5KStCm5aYvhfBJb8cHol6 but is a short placeholder/invalid value, not a real Metabase API key for https://warp.metabaseapp.com. Same failure mode as 2026-08-10. Posted failure notice to #growth-docs. Action needed: replace the secret with a valid Metabase API key and re-run.
