Default: bump nixpkgs + tracey to latest
nix flake update nixpkgs
nix flake update tracey-src # tracey source is a flake input (IFD-free since c1d6a05)
git add flake.lock
Then show the user the flake.lock diff. Do not commit — the user reviews and commits.
With a specific input argument (/bump-refs nixpkgs)
nix flake update $ARGUMENTS
git add flake.lock
Show the diff. Do not commit.
Post-bump
Remind the user that the next nix develop / build will re-fetch inputs and may rebuild. The crane cargoArtifacts cache survives.
tracey bump extra step: if tracey-src was bumped and pnpmDeps hash changed, one fakeHash roundtrip is needed — see memory tracey-adoption.md.
