Review under the unattended Renovate merge rule: lock file maintenance

Renovate's refresh moved one input: nixpkgs (nixos-unstable) from 3ec6363 to 1c89083. That channel release was pushed on 2026-10-30 20:20 UTC, so it was under three days old at review time.

Trim. Commit 757a6ba pins nixpkgs back to 31ecbac, the newest nixos-unstable channel release that is at least three days old. It was pushed on 2026-10-28 02:53 UTC. No other lock node moved, and the repo holds no hash computed from the lock, so nothing else needed to change.

What moves. Lock-file maintenance has no release notes, so I compared the tools the flake takes from nixpkgs at both revisions. bash, coreutils, gawk, git, herdr, jq, shellcheck, gnused, gnugrep and findutils resolve to the same versions. bd comes from the beads input, which did not move. Nothing moves a major, and nothing talks to an outside service with a version skew to respect.

Safe to take once the required checks pass on the trimmed head commit.
