The oracle no longer uses Fusion measurements. tests/oracle/<case>/ now holds the 76 recipes (our own format, with recorded measurements and tool-specific fields removed) and an expected.json per case: - 55 analytic cases: closed-form values from tools/oracle-analytic/ (stdlib Python, formulas in each case's "method"). - 21 FreeCAD cases: the same recipe built with FreeCAD's public scripting API by tools/freecad-oracle/ (an external program, not a dependency), with a reference.stl for 20. solvecraft-cli oracle compares body count, volume, area, centre of mass, bbox, face counts where the geometry fixes them, and, against reference.stl, the sampled Hausdorff distance and the principal moments (spatial.rs from #301). cargo xtask oracle reads tests/oracle, writes docs/oracle.md with the source of each value, and supports known_failure marks for tracked bugs. CI runs it on every PR; a manual workflow regenerates the FreeCAD values. step-corpus, seam normalisation and the through-all emulation, which only existed to compare with Fusion, are removed. 75/76 pass; 75-sm-bracket-holes is a known failure (#296).

SolidCraft
SolidCraft is an open-source parametric 3D CAD application written in pure Rust. Sketch on a plane, constrain and dimension the sketch, turn profiles into solids with features on a timeline, and change a parameter to watch the whole timeline rebuild.
It runs as:
- a desktop app for Windows and Linux (egui + wgpu);
- a web app in the browser (wasm, WebGPU or WebGL2), try it here;
- a headless CLI,
solvecraft-cli, that runs command scripts, measures and exports; - an MCP server that AI agents model with, headless or driving the running app.
Everything the user can do is a command with JSON parameters. The toolbar, the dialogs, scripts, the CLI, the control channel and MCP all run the same commands, so anything you can click you can also script, test or hand to an agent.
SolidCraft is early. Sketching, solid modelling, parameters, components with joints, sheet metal and a plastic-enclosure subset work; surfaces, drawings, CAM and simulation are deferred. The roadmap has the details, and command parity and the reference tests measure how far along it is.
Existing .solvecraft designs and solvecraft-cli commands keep their names and behavior.
This book has two halves: the user guide for people modelling with SolidCraft, and the developer guide for people working on it. The command reference is generated from the code on every build.
