MeshContract v0.2.1

• Reject OBJ input that contains vertices but no faces.
• Handle overflowing geometry limits safely as a structured contract error instead of an uncaught OverflowError.
• Add regression tests.

MeshContract v0.2.0 — JSON and CI foundation

MeshContract v0.2.0 adds the foundation for using 3D asset contracts in automated pipelines.

Highlights:

• Stable JSON output with --format json
• Structured machine-readable contract violations
• Backend-independent ValidationResult / Violation models
• CI-friendly exit codes
• Copyable GitHub Actions example
• Improved package metadata for future PyPI distribution
• Backward compatibility with v0.1 YAML contracts and text output
• 25 tests
• CI verified on Python 3.11 and 3.12

Current asset support remains Wavefront OBJ.

MeshContract v0.1.0 — OBJ validation MVP

First public MVP of MeshContract: requirements-as-code for 3D assets.

• Wavefront OBJ validation with YAML contracts.
• Checks vertices, faces, virtual triangle count (polygon faces are virtually triangulated), and bounding-box dimensions.
• Supported geometry rules: max_triangles, max_vertices, max_width_m, max_height_m, max_length_m, allow_ngons.
• CI-friendly exit codes: 0 when the contract passes; non-zero when violations are found.
• 22 unit tests; GitHub Actions CI runs on Python 3.11 and 3.12.
• Core validation uses backend-independent models, ready for future 3D backends.
