The single module-eval derivation forced ~62 full nixosSystem fixtures live at once to compute its cases list: 10.6GB peak RSS / 5m25s to evaluate, by far the dominant cost in nix flake check. Splits it into 21 independent checks.module-eval-* derivations (1-7 fixtures each) sharing builders/helpers via module-eval/lib.nix, so no single derivation needs more than a handful of fixtures live at once. A few cases spanning two clusters carry a small duplicated fixture rather than threading shared state through lib.nix.
