nixos/nixcontainer.dockerTools.buildLayeredImageproduces a deterministic OCI image(
f5fd0e54…), identical across two environments. Lab 6'sdocker build --no-cacheproducestwo different digests. Chose
buildLayeredImage+fakeRootCommandsoverbuildImage+runAsRootbecause the latter needs KVM and fails inside a container..github/workflows/nix-repro.yml— two parallel replicas on fresh runners, third jobasserts digest equality. Green run, deliberately-broken red run, and post-revert green run all

sandbox = true. Documented insubmissions/lab11.md.
