tasty-cache: Nix-style test caching for Haskell
Summary
The tasty-cache README presents an AI-assisted Haskell test-caching tool that uses GHC HIE files to fingerprint and skip unchanged tests, speeding CI runs. It explains the architecture (fingerprints, BFS over HIE graph), how to enable caching with an opt-in cacheable wrapper, and practical caveats. Useful for readers interested in AI-assisted software tooling, CI optimization, and Nix-based Haskell workflows.
