* modelcraft-io: the .modelcraft file (modelcraft/1), atomic writes, autosave storage A stored ZIP of a manifest (format tag, geometry sources with SHA-256, part sizes and hashes), the model definition as stable pretty JSON, the mesh and geometry tags in a compact binary part, and the journal one command per line. Reading caps every size, checks every checksum and replays the model through its checked methods. Model::without_mesh and empty mesh fields left out of the model's JSON; geometry::read_file. Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * engine: undo/redo on the journal, file.open/save/save_as, autosave and recovery CommandSpec gains a kind: Model commands are journalled and become undo steps; Session commands (file.*, edit.*) manage the session. Undo history is bounded by steps and estimated memory. Geometry sources are recorded with content hashes and reopened on file.open (missing or changed files are warnings). Desktop app autosaves every 30 s and reports recoverable models; Ctrl/Cmd+Z and Shift+Z/Y undo and redo.

ModelCraft
An open-source, clean-room CAE modeling application in pure Rust: geometry to analysis-ready finite element models, with robust tetrahedral and hexahedral meshing, solver decks for Abaqus, Nastran and LS-DYNA, and its own linear static and modal solver. Desktop, browser and AI agents drive the same commands.
Status: early. The workspace, quality gates, the FE model, the command engine and the geometry boundary (SolidCraft's kernel and tessellator) are in place; meshing is next. See ROADMAP.md.
Build
cargo xtask ci # fmt, assets, licences, layers, clippy, tests, wasm
cargo run -p modelcraft-cli -- commands # every command and its parameters
cargo run -p modelcraft-cli -- run script.json # run a command script
Rust 1.95 or later, with the wasm32-unknown-unknown target for cargo xtask ci.
