- Star-schema topology: facts filter to dimensions through many-to-one relationships.
- Ambiguous paths between facts and dimensions.
- Fact-to-fact relationships and accidental bridge paths.
- Many-to-many risk and bridge-table requirements.
- Active/inactive relationship strategy and role-playing dates.
- Cross-filter direction and bidirectional filter risks.
- Unsupported DirectQuery, composite model, or live/OLAP edits.
Output Requirements
- Include relationship inventory, invalid paths, severity, and remediation.
- Mark models as
pass,pass-with-risk, orfail.

- Use
scripts/powerbi_expert_factory.py validate --project <pbip-folder>for the current local static model-graph gate. - Treat any
model_grapherror as release blocking.
