Prove a Tableau migration's live database sources are reachable through the Power BI artifact that will ship. Use before builders start on any workbook/datasource with live sources, when a Desktop refresh stops on a sign-in or other dialog, or when sign-off needs real-data evidence for a live source.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Live-source reachability Use this before any builder starts on a workbook/datasource with live database sources. Prove that the **Power BI artifact you will ship** can reach its source. A Python, SQL client or Tableau-only check does not use Power BI Desktop's credential store, so it proves nothing here. Run it **before dispatching builders**. START_READY can admit `live_unproven`; it is not data proof. There is no write-time enforcement. Use the existing [`pbip-model-refresh` procedure](../pbip-model-refresh/SKILL.md#automatic-callers---automatic-source-scope-780), with its Desktop, bridge and client-library prerequisites; do not create a second refresh route. ## Run order 1. **Classify the sources (read-only, no network).** ```powershell python scripts\preflight_source_credentials.py --spec <spec> ``` Any live database source needs steps 2 to 5. No live source: record that and stop here. 2. **Check the emitted artifact before opening Desktop.** ```powershell python scripts\check_bundle_sources.py <bundle> --spec <spec> ``` Non-zero means a static finding or unavailable input, not a credential diagnosis.

How to install
mdr add guust-franssens/tableau-to-powerbi-migration/live-source-reachability@sha256:ea6889dec818a1b0The line at the top of this page pins the label git:20261105.1fee875, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
