nixpkgs-multiverse introduces a 'fast mode' that provides direct store paths for any historical package version without downloading or evaluating the full Nixpkgs tree. By querying a cache-first index, users can bypass the traditional evaluation penalty and realize outputs straight from binary caches. This represents a fundamental shift in how Nixpkgs version histories are accessed and used.
Background
Nixpkgs is the massive package collection for the Nix package manager, but accessing specific historical versions traditionally required fetching and evaluating the entire repository. This new capability shifts the model from evaluation-based lookup to direct cache-path resolution.
