🔍 Arkana PR Review — ArkLabsHQ/enclave#33

Summary: Dependabot bump of cachix/install-nix-action from v27 → v31 across two CI workflows (integration-test.yml, release.yml).

Changes: Minimal — two line changes, version tag only. No config changes to nix_path or extra_nix_config.

Assessment:

  • ✅ Safe upgrade — v31 brings Nix 2.27→2.34.2 with several security patches (privilege escalation fix in 2.29.1, macOS root execution fix in 2.30.1)
  • ✅ No breaking changes to action inputs/outputs between v27 and v31
  • ✅ Semantic versioning now used by install-nix-action starting at v31 — future minor/patch updates auto-included under the v31 tag
  • ⚠️ Minor note: The jump skips v28-v30 entirely. The release notes mention a rollback of Nix 2.34.0 due to cachix-action auth key issues, but 2.34.1 fixed that. Current v31 pins to 2.34.2 which is stable.

Verdict: Clean dependency bump with security improvements. No concerns.
