The engineering under the product.

Replacing fragile face IDs with geometric coordinate signatures, so an edit doesn't break on a renamed face.

Why every OrionFlow model is a FeatureGraph first — one representation that compiles to FreeCAD and build123d alike.

How we prove a generated model rebuilds to the exact same solid — down to the cubic millimetre.

Why we manufacture our own text-to-CAD training data instead of scraping it, why we build it in FreeCAD, and how every part is proven correct before it earns a place in the corpus.

Multimodal extraction: feature graphs, rolling geometry, sketch constraints, and topology-stable anchors as training signal.
