description	Update Nix flake inputs in persops. Use when asked to update flake.lock/inputs, update AI inputs (codex-cli-nix, claude-code-nix, llm-agents), or run full `nix flake update`, then verify with `nix flake check` and commit the update-only changes.

Nix Flake Update

Workflow

1. Decide scope
   • AI update: run nix flake update codex-cli-nix claude-code-nix llm-agents
   • Full update: run nix flake update (default when user does not mention AI)
2. Switch
   • Run make local after any update
3. Handle Pi changelog once
   • Run pi --version 2>&1 once after switching.
   • Compare it with modules/ai/pi/settings.json lastChangelogVersion.
   • If different, bump lastChangelogVersion to the current Pi version, read installed Pi CHANGELOG.md, and summarize entries between the old and new versions in the handoff.
   • If already equal, say no Pi changelog news.
4. Verify (full updates only)
   • Run nix flake check
   • If failure, quote exact error, fix only update-related fallout, rerun nix flake check
5. Commit
   • Stage only update-related files (typically flake.lock, modules/ai/pi/settings.json when Pi changed, maybe flake.nix or other necessary fixes)
   • Use Conventional Commit, keep commit isolated to the update
   • Examples: chore(nix): update flake inputs or chore(nix): update ai inputs
