Spline distortion beats OpenCV for cheap lenses; swappable API outclasses mrcal's overhead.
Rotation-invariant calibration that stays zero when you rotate the phone — most apps fail this.
Six-dimension scoring for Claude skills when nothing else measures quality this way.
Comprehensive checklist, but CLAUDE.md and cursor rules already solve this locally.
Encrypted semantic search via modular arithmetic—98% quality, 8x faster than homomorphic encryption.
Replaces Google Nest's $20/month cloud analysis with local Qwen 35B and a 3D-printed head.
