- Line 421: Update the Helm version-mismatch diagnostic in the platform-specific
installation flow so the Homebrew/current-stable explanation is emitted only for
macOS; in the Linux branch, use a generic message instructing manual
installation of the pinned HELM_VERSION. Keep the existing mismatch validation
and version references unchanged.
- Line 398: Update the Helm setup logic around installed_helm_version to
determine Homebrew ownership with brew list --versions helm, selecting brew
upgrade only when a Homebrew Helm record exists and brew install otherwise;
retain PATH version handling separately. Add a hermetic macOS regression case
covering a stale manually installed helm binary with no Homebrew Helm record.

- Around line 90-102: The Helm test currently verifies only source text rather
than runtime behavior. Replace or supplement the grep-only checks in the test
with hermetic mocked helm and brew scenarios that exercise the setup decision
logic: assert stale Homebrew-managed Helm invokes brew upgrade helm, stale
unmanaged PATH Helm invokes brew install helm, and a post-install version
mismatch reports the expected error.

- Around line 206-208: Make both Helm version-mismatch branches in install_helm
return non-zero after log_error, and update the related setup-tools test to
expect run_install_helm failure while still asserting the diagnostic message.

check-tools compared helm by major version only, so a patch-version mismatch against the .settings.yaml pin (e.g. v4.2.4 installed vs v4.3.0 pinned) reported a false pass while pkg/oci's OCI-chart tests still fail on that same drift. Switch helm's match_strategy to strict_exact. setup-tools only checked for helm's presence before installing, so a stale Homebrew install was never upgraded to the pinned version and setup-tools reported success without noticing the drift. Compare the installed version against HELM_VERSION before and after the install step, and use brew upgrade when a stale Homebrew install is found. Return non-zero from install_helm on a post-install version mismatch instead of just logging: setup-tools calls it unguarded, so with set -euo pipefail this now aborts setup instead of reporting success with an incompatible Helm. Fix the matching test gap: the mismatch case's failure was invisible to run_install_helm's own set -e because it ran as the tested command of an if in the caller, and bash ignores -e for the full extent of a compound command under test that way -- including nested subshells that re-enable it themselves. Capture the exit code explicitly instead. Also replace the Helm version literals used across these tests with obviously-fake values (e.g. 9.9.9) instead of numbers that happen to match the real .settings.yaml pin, so a future Helm bump doesn't look like it needs a matching test edit.

Summary
Make Helm version checking exact rather than major-version-only, so
make tools-checkandmake tools-setupactually catch and fix the drift thatpkg/oci's OCI-chart tests already treat as a hard failure.Motivation / Context
TestHelmPinnedVersionExplicitVersionPullrequires the exact Helm version pinned in.settings.yaml, buttools/check-toolscompared Helm by major version only, so a patch-version mismatch (v4.2.4 installed vs. v4.3.0 pinned) showed a passing checkmark right before that same drift failed the test.tools/setup-toolshad the matching gap on the install side: it only checked for Helm's presence, so a stale Homebrew install was never upgraded to the pin.Fixes: N/A

check-tools's Helm entry switchesmatch_strategyfrommajortostrict_exact.setup-toolsnow reads the installed Helm version up front, compares it againstHELM_VERSION, and on macOS runsbrew upgrade helmwhen a stale install is found instead of skipping straight past it becausecommand_exists helmwas true. It re-checks the version after install/upgrade and errors out with guidance if Homebrew's current stable release still doesn't match the pin, since Homebrew can't install an arbitrary older Helm release.Testing
# Commands run (prefer `make qualify` for non-trivial changes) make qualifymake qualifypassed. Also ran the hermetic script tests directly:Both pass, including the new Helm
strict_exactcases (accepts-exact-helm,rejects-mismatched-helm,rejects-unreadable-helm,rejects-missing-helm) and thesetup-toolsregression guard for the version-compare/brew upgradebehavior.Risk Assessment
Rollout notes: N/A. Dev-tooling scripts only; no runtime or CI-pipeline behavior changes for anyone whose local Helm is already on the pinned version.
