Commits were taking up to 80s warm. Two causes: - The osv-scanner hook runs `make scan` on any go.mod/go.sum change, resolving all 1444 go.sum entries against the osv.dev API. Warm, that is ~71s of the ~78s a dependency commit took. The osv-scanner workflow already scans on push and on every pull request, so this was duplicate coverage bought at the cost of blocking commits. - golangci-lint ran twice per commit: once as `run --fix` from `make fmt` and again as `run -v` from `make lint`. Split formatting from linting: `make fmt` now runs `golangci-lint fmt` (formatters only, ~0.8s), and a new `make lint-fix` target carries the single `golangci-lint run --fix` pass that the pre-commit `lint` hook uses. Linting still gates the commit, and the linters that can repair their own findings still do so. `make lint` is unchanged, so CI keeps reporting rather than rewriting. Drop `go fmt ./...` from `make fmt`; the gofmt formatter in `golangci-lint fmt` supersedes it, and unlike `go fmt` it honors the third_party, builtin and examples exclusions in .golangci.yaml. Vulnerability scanning leaves the commit path via dev-kit v2.0.0, which disables the osv-scanner hook by default, so no per-project override is needed. Pin the dev-kit flake input to the v2.0.0 tag. It carried no ref, so `nix flake update` resolved it to whatever `main` happened to be; that is how the lock reached d7e7744, an untagged mid-stream commit that skipped the v1.0.14 and v1.0.15 releases. Align DEV_KIT_VERSION, which pins the downloaded common.mk, to v2.0.0 as well -- it was on v1.0.13, so the two dev-kit references had drifted apart and now move together. Document the split in docs/CONTRIBUTING.md: the target table gains `make lint-fix`, and the contributor fix workflow now points at it instead of the report-only `make lint`. Warm commits go from ~6.9s (code) and ~78.5s (dependency) to ~5.5s. Closes #669

What
Closes #669
Speed up the pre-commit hooks: warm commits drop from ~6.9s (code change) and ~78.5s (dependency change) to ~6s.
Why
Two independent causes, found by measuring each hook step:
make scanon anygo.mod/go.sumchange, which resolves all 1444go.sumentries against the osv.dev API. Measured 64.6s with default flags vs 0.10s with--offline-vulnerabilities, so it is network latency, not local work..github/workflows/osv-scanner.ymlalready scans on push and on every pull request, so this was duplicate coverage paid for by blocking commits.run --fixfrommake fmt, then again asrun -vfrommake lint.A popular theory was that
web/node_modules(375M, 26203 files) was slowing the scans. It is not: osv-scanner honors.gitignoreand scans that tree in 0.09s, andmake fmt/make lintoperate ongit ls-files, so nothing in the hook chain walks the untracked tree.Testing
forbidigo+unusedviolation fails thelinthook atMakefile: lint-fix, exit 1.importasrewrotemetatometav1(declaration and usage) andmisspellfixedrecieve; the first attempt aborts with "files were modified by this hook" and the second passes aftergit add.make lintstill runs in the commit path, 19 of the 56 enabled linters can autofix and still do.make fmt,make lint-fix,make lint,make shellcheckandpre-commit run --all-filesall exit 0.make codegenproduces no diff.Notes for reviewers
No API, CRD, or RBAC changes. Three behavioral changes worth a look:
make fmtno longer gates. It formats only;make lint-fixis what fails the commit.make lintis untouched, so CI reports rather than rewrites.nix flake updatelanded on whatevermainwas; the lock had reachedd7e7744, an untagged mid-stream commit that skipped v1.0.14 and v1.0.15.DEV_KIT_VERSION(which pins the downloadedcommon.mk) moves from v1.0.13 to v2.0.0 so both dev-kit references travel together; the only functional delta in that range is a one-linemake cleanfix. Nothing will now notify you of new dev-kit releases, since Renovate has nonixmanager configured andDEV_KIT_VERSIONis not covered by the custom managers inrenovate.json.Not addressed: on a genuinely cold cache (fresh clone, or after a toolchain or dependency bump) the hooks still take ~205s. Measured, ~142s of that is compiling the Go dependency closure into
~/.cache/go-build, which is shared withmake testandgo buildand would be paid on the next build regardless. That is build-cache cost, not hook cost, and no hook change can remove it.Checklist
