Verity: a calibrated forensic comparison

Verity: a calibrated forensic comparison engine. It compares 3D scans of bullets, cartridge cases, and toolmarks and reports a calibrated likelihood ratio instead of a yes/no "match." It's the production version of my PhD research: a Rust core with Python and R bindings, a FastAPI service, and a web app with a public benchmark leaderboard. The validation results, including where the method falls short, are published with the code.
