Publication holds

  • Claude and Grok timed out during their bounded attempts, so independent external review is absent and explicitly waived for this published reviewable draft.
  • IFC defines IfcBuilding as a subtype of IfcFacility while the Vercy registry uses Facility CONTAINS Building; the operational Vercy relation is retained but requires a formal crosswalk decision.
  • Building-code, structure-subtype, structural-safety, energy and jurisdiction profiles need competent specialist review before operational enforcement.
  • Certified IFC and CityGML field mappings, model-view constraints and round-trip tests remain unverified for canonical conformance.
  • Independent external review was explicitly waived by the repository owner; this codex-only result remains a reviewable draft.

Deferred research

  • Validate the base against building, bridge, tunnel, tower, dam, retaining-structure and temporary-works subtype profiles.
  • Develop formal structural, fire, accessibility, energy, indoor-environment and climate-hazard profile recipes with jurisdictional authority.
  • Create certified IFC 4.3 and CityGML 3.0 crosswalks with model views, levels of detail, validation fixtures and declared information loss.
  • Approve sibling model identifiers and relation cardinalities for sites, parcels, spaces, equipment, materials, works, permits, incidents and documents.
