Vera Qs

• IfcMaterialLayerSet: Verify presence on IfcWall, IfcSlab, IfcBeam.
• Material Selection: Cross-check against references/material_registry.md.
• Naming: Ensure no "Generic" or "Placeholder" materials in production models.

2.2 Quantity Presence

• IfcElementQuantity: Check for existence of Area, Volume, and Length.
• Consistency: Verify NetArea and GrossArea fields are populated.

2.3 Classification Validation (v0.2)

• IfcClassification: Verify elements (IfcWall, IfcSlab) have UniClass-2015 or authorized local codes.
• Reference: Cross-check against classification artifacts in SOT.

3. Checklist (Deterministic)

• Material Match: IfcMaterial.Name exists in material_registry.md.
• Classification Check: Elements have IfcClassificationReference (UniClass) assigned.
• Quantity Existence: Qto_*_BaseQuantities set is present on all structural elements.
• GlobalId Integrity: No duplicates found in the evidence set.
