Run

ifcdiff rev-a.ifc rev-b.ifc --format markdown

Which walls moved and by how much. Which properties changed. Quantity deltas by class — and, the part that matters in a payment meeting, what caused them. Markdown for a pull request, HTML for a CI artifact, JSON for a script, BCF 2.1 for the coordination tool everyone already has open.

What makes it different

Quantity deltas decomposed by cause, not just reported as a number
Four outputs from one run: Markdown, HTML, JSON, BCF 2.1
Standard library only — no geometry kernel, no server, nothing to install but the package
