Leaving toolchain versions to runtime resolution breaks reproducibility across teams.

Nix's hermetic builds and Cosign's keyless signing create verifiable software supply chain evidence.

Nix's hermetic builds need external attestation to meet SLSA requirements.

Overlays patch vulnerabilities across your entire dependency graph, not just one package.

Lock files alone won't stop supply chain attacks without review discipline.

Keeping SBOMs in sync with dependency bumps prevents silent audit failures.

Nix's pure-function model produces SBOMs that need careful schema mapping to validate correctly.

Nix's derivation-based provenance breaks standard SBOM tools designed for filesystem scanning.

Nix Flakes and automation ensure reproducible, audit-ready dependency inventories at every build.

Content-addressed paths let Nix skip rebuilds and verify outputs without trusting the cache.
