theorem on a triangle mesh.

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.

## Input schema

- `compute_curvatures` *boolean* — Whether to compute per-vertex curvatures (default true).
- `triangles` *string* (required) — JSON array of triangle index triplets (CCW winding), e.g. `[[0,1,2]]`.
- `verify_gauss_bonnet` *boolean* — Whether to verify the Gauss–Bonnet theorem (default true).
- `vertices` *string* (required) — JSON array of 3D vertex positions, e.g. `[[0,0,0],[1,0,0],[0,1,0]]`.
