Topology checks look for open boundaries, shared-edge anomalies, degenerate triangles, duplicates, and normal mismatches.
Mesh repair
A mesh repair workflow built around inspection first.
The safest repair starts with topology diagnostics: count the issues, explain their print risk, and only apply supported edits.
Repair actions are intentionally conservative so the output can be compared against the original mesh report.
The V1 engine is pure TypeScript so checker logic can run in the browser and be reused by the server path.
External engines such as ADMesh or PyMeshFix remain benchmark references until license and runtime risks are resolved.
