+SolidCraft is a clean-room, open-source, pure-Rust parametric 3D CAD application in the style of
 Autodesk Fusion: sketches with a constraint solver, a parametric timeline of features, a B-rep
 kernel, and a desktop UI that agents can drive. Siblings with the same conventions live next to
 it in `storytold/`: `cadcraft` (AutoCAD-style, the closest relative), `photocraft`, `vectorcraft`,
 `gridcraft`, `designcraft`, `wordcraft`, `deckcraft`, `soundcraft`. Repos don't share code; when
 code is adapted from a sibling (MIT OR Apache-2.0) it is noted in ATTRIBUTION.md.
 
+## Product name and compatibility
+SolidCraft is the displayed product name; `solidcraft` is the repository name. Keep existing
+`solvecraft` crate/binary names, `.solvecraft` files, format markers, environment variables,
+settings/recovery paths and package IDs compatible. Published SolveCraft release artifacts
+and attribution records keep their historical names. Public docs/web/Flatpak deployments
+use project Pages `/solidcraft/`; do not add permanent old-name Pages aliases. See README's
+compatibility notes.
