Fast Match Finder Uses Graph Validation

Fast Match Finder is an open-source timed perception game that models a 57-card deck as a projective plane graph and uses Neo4j as authoritative validation. The repository (with quickstart) supports optional OpenAI vision-based AI opponents, PNG rendering, and API endpoints for round creation, validation, and AI play; Neo4j is optional with an internal math fallback. Run locally via uv run uvicorn main:app and access http://localhost:8000.
