The flake pins sixteen tools by hand and nothing was watching them, so they would drift the way the `go install` lines they replaced used to. Renovate can watch them, but only halfway: it can edit a version string, and it has no idea what the source tarball or the vendored module tree underneath that version hashes to. So split the job. A custom manager reads the `# renovate:` comments now sitting above each entry in `toolVersions` and bumps the version; a workflow on Renovate's branches then runs hack/nix/update-hashes.sh and commits the hashes that go with it, before anyone reviews the PR. The script drives nix-update, which refetches rather than builds — a fixed-output path is named after the hash it is *expected* to have, so a stale download of the old version already sits where the new one would go, and an ordinary build reuses it without a murmur. That makes the script the answer for a bump by hand too, so running-locally.md now says to run it rather than pasting hashes out of build errors. Three pins are deliberately left alone and say so in place: cspell follows nixpkgs, since the flake asserts on the version nixpkgs ships; the kube-openapi commit is the one the checked-in OpenAPI definitions were generated from; and OpenAPI Generator decides what the Java SDK downstream users compile against looks like. k8s.io/code-generator is held to patch releases, because its minor has to match the apimachinery in go.mod. None of these automerge, unlike the rest of the patch updates on main: the point of the pinned tier is that a version change gets read by someone, and the hashes only arrive in a second commit. properdocs is grouped so its two homes — the docs build and the nix shell — move together. The nixpkgs pin itself, which moves every floating tool at once, is weekly and reviewed. The workflow wants the GitHub App that used to push gomod2nix.toml, under NIX_UPDATE_APP_ID and NIX_UPDATE_APP_PRIVATE_KEY. Without them it falls back to GITHUB_TOKEN, which still pushes but leaves the PR's other checks unstarted. Nothing needed deleting: no rule named the pin locations PR1 removed, and the flakes it deleted under dev/nix and sdks/java were only ever matched by the `nix` manager's default file pattern.
