…he version it ended with; pin the mage and benchstat hints (celeris#838) mage Tools fell back to `go install .../h2spec@latest`, which resolves to v2.2.1+incompatible (it reports Version: 2.0.0, one test case fewer), and its download path fetched the amd64 tarball on every architecture, so an arm64 Mac or Linux host got a binary that cannot run, with rc=0. It also accepted any h2spec already on PATH. Tools now builds the commit the v2.6.0 tag points at, as a pseudo-version the module proxy serves, with the -ldflags of h2spec's own Makefile, on every GOOS/GOARCH. It checks the version the result reports and the one PATH resolves, fails with the release URL when either is not 2.6.0, and prints the version and path it ended with. CONTRIBUTING pins mage to v1.17.2 (what CI installs) and names CI's golangci-lint v2.13; bench-ab.sh runs the benchstat that .github/tools pins with `go tool`, and Dependabot bumps it there.
… pinned module version; bench-ab.sh runs benchstat with GOWORK=off (celeris#838) The 2.6.0 version string is the -ldflags stamp Tools itself applies, so it said 2.6.0 for any code. Tools now reads the installed binary's build info and requires github.com/summerwind/h2spec@v1.5.1-0.20200804131034-70ac22940108, and prints the module it was built from. go refuses -modfile in workspace mode, so bench-ab.sh stopped for a contributor with a go.work; both go tool calls now run with GOWORK=off. golang.org/x/perf has no tagged release and Dependabot's version updates propose tagged versions only: the tools go.mod and dependabot.yml now say the benchstat pin moves by hand.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Early return trusts the version string only.
Line 108 accepts any PATH h2spec whose --version prints 2.6.0. The -ldflags stamp sets that string for any code. A wrong-commit build passes on the next mage tools run, as the PR notes. The comment on Lines 90-92 says build info is what proves the code, but this path skips that check.
Call h2specBuiltFrom(path) before the early return. Compare it to h2specMod + "@" + h2specModVersion. Binaries not built with go install of the pinned module, such as the release amd64 binary, may report a different Main.Version. If so, they fall through to the reinstall. If the PR defers this to #890, keep the deferral. Then update the comment on Lines 90-92 so it does not claim a check that this path skips.

…(celeris#838) (#485) CONTRIBUTING.md now installs mage from the CI tools module (go run -modfile=.github/tools/go.mod), the same pinned version CI uses, instead of mage@latest. This is the probatorium part of goceleris/celeris#838; the celeris part is goceleris/celeris#910.
Part of #838. goceleris/probatorium#485 fixes the rest: probatorium's CONTRIBUTING.md:7. #838 needs both PRs: once both have merged, close it by hand.
Defect
mage Toolscan end with an h2spec that is not 2.6.0, and it still exits 0 without saying which version it installed. Line numbers are at 2ca5d72, unchanged at c88d843, this PR's base.go install github.com/summerwind/h2spec/cmd/h2spec@latest(magefile.go:93 and :108) resolves to v2.2.1+incompatible. That build reportsVersion: 2.0.0and has 146 test cases. The v2.6.0 release has 147.h2spec_<goos>_amd64.tar.gzon every architecture (goarch := "amd64", magefile.go:89).mage toolsexits 0 and leaves an x86_64 binary that fails withBad CPU type in executable(rc 126).mage@latest, while CI installs v1.17.2..github/scripts/bench-ab.sh:41,50usesbenchstat@latest.Mechanism
@latestlands on v2.2.1. h2spec's tags after v2.2.1 carry a go.mod without the/v2suffix. The module proxy therefore has no version for them:go install .../h2spec@v2.6.0and@v2.6.0+incompatibleare both refused with "module contains a go.mod file, so module path must match major version".@latestgets v2.2.1+incompatible.v1.5.1-0.20200804131034-70ac22940108, with its own go.mod pins.-ldflags "-X main.VERSION=2.6.0 -X main.COMMIT=<sha>". So the string says 2.6.0 for any code built with that stamp.Fix
h2spec (magefile.go)
Toolsbuilds that commit with the same ldflags:go install -ldflags=... github.com/summerwind/h2spec/cmd/h2spec@v1.5.1-0.20200804131034-70ac22940108.curl | tarpath, which had no checksum, is gone.Toolschecks three things:github.com/summerwind/h2spec@v1.5.1-0.20200804131034-70ac22940108(round 1);Toolsapplies, so the build-info check is what proves the code. An edit back to@latestnow fails the firstmage toolsafter it, which names the module version it found. Before, it printed 2.6.0.Toolsreads only the version string. So a secondmage toolson the same machine accepts the build. The fix changes howToolsbehaves, so it is an item on v1.6.0 polish: CI and tests #890 rather than a change here.Toolsfails and names the binary and the release URL. That covers:h2spec: 2.6.0 at <path> (built from github.com/summerwind/h2spec@v1.5.1-0.20200804131034-70ac22940108).must(Tools())(mage_compliance.go:74) now stops FullCompliance wheneverToolsrefuses. Before, on linux/arm64 it got an amd64 binary that cannot run, and the spec-test failure was "tolerated" (:76-78). That is the intended fix.The other hints

mage Tools. Magefiles also cannot be tested in the root package, because the root package iscelerisand the magefiles aremain. So the regression test is a black-box Go test in the lane evidence.The test is

It runs the realmage tools(mage v1.17.2) of a tree with a private GOBIN, GOPATH and PATH, then checks what PATH ends up resolving.

Two reviews of fe509c8 found no blocker or major. The correctness review re-ran the test on darwin/arm64, linux/arm64 and linux/amd64 with its own mage and module cache, against main 874ebf4 (whose magefile.go is c88d843's). It got the same results on all three: base 0 pass / 6 FAIL, this branch 6 PASS / 0, and the
cpnegative control 0 / 6 FAIL. Its own second controls were caught: goBinDir ignoring GOBIN gave 0 / 2, and dropping the stamp gave 0 / 1. Logs:review-correctness-r1/r1x-logs/838-{host,linux-arm64,linux-amd64}-summary.log, under the lane evidence dir.The head is still fe509c8. This round changes only this text.
mage toolsaccepts the stamped build the first run refused, because the early return reads only--version. The review'sTestReviewerRefusalIsStickyFAILs at fe509c8 on all three platforms (lane evidencereview-correctness-r1/r1x-logs/838-*-P-probe-sticky-head.log).Toolsbehaves, so under the polish rule it is an item on #890, with that test as its failing test. The Fix section above now says the refusal holds for one run.The fork-claim audit for #864 in this round also found celeris's
.coderabbit.yaml:184, which says fork code never runs on a self-hosted or macro runner. That is a second #890 item. Neither item is part of this PR.
