Graph Board for ZXW

An online graph board for the ZXW calculus live at zxwgraphboard.netlify.app. ZXW calculus is a specific kind of tensor network that can represent complex linear algebraic computations in diagrams. Users place vertices, wire them with edges, and compute the tensor the diagram represents via a Rust/WASM backend. The app is client-side only.

• User guides + dev docs available at: zxwgraphboard-doc.netlify.app (source: the doc/zxw-graphboard-doc git submodule).
• Operating manual for this repo: AGENTS.md — commands, layout, architecture invariants, persistence rules.
• Compute-backend design: doc/plans.md — the contract for the Rust compute layer; its status block at the top says which phases have landed.

• pnpm dev — dev server (Next.js).
• pnpm test — frontend tests (vitest).
• cargo test — Rust compute-layer tests (cargo llvm-cov --workspace for coverage).
• pnpm ping:wasm — quick smoke test of the WASM pipeline.

• pnpm build:wasm — build the Rust backend via wasm-pack (scripts/build-wasm.sh). Run before pnpm build and after any Rust change. Output lands in public/wasm/zxw/ (gitignored).
• pnpm build — build the frontend into .next/.

Manual Netlify deploy: pnx netlify deploy --prod (pnx = pnpm exec; --prod = production). netlify.toml runs build:wasm + build before uploading .next/; the wasm binaries are never committed.

• Two git submodules: doc/zxw-graphboard-doc (docs site) and crates/cartographer (treewidth research CLI, kept for planned later integration).
• Two Rust crates in the root Cargo workspace; default-members keeps cargo test on the zxw compute crate.
