Collect the measurement lessons, and drop the orphaned guard script The corrections this document accumulated are the most transferable content in it: anyone measuring a Nix build on a real machine will hit at least one of a per-derivation upload hook, keep-outputs making deletion a no-op, a repeated identical mutation measuring the cache, or a divided total inheriting every contaminant in it. Collected as rules, separated from this repository specifics, with the cost tables left clean. scripts/check-graph-agreement.mjs went unreferenced when the guard was rewritten to ask pnpm instead of comparing a generated table against the manifests it was generated from.
