HouseIR synthetic MEP evaluation — October 4, 2026
This is a scripted edit, not an AI-generated edit or a customer production model.
Change: extend a straight 50 mm diameter pipe from 1000 to 1400 mm.
Tests independently inspect IFC radius/depth, endpoint positions, pipe and port
GlobalIds, open endpoint topology, system membership, and the exact unchanged
neighbor fingerprint. These tests pass for this fixture.
The compiler report discloses its verification scope and geometry reference.
This is not engineering certification, universal MEP support, or native RVT export.
A separate regression refuses uncertifiable bent-network fitting geometry.
before.bir and after.bir show the requested change; IFC files permit independent review.
No API key, signing key, sealed residual, or customer data is included.
