v0.4.2

CervoMutants v0.4.2

Changelog

Changed

• Hosted external-wave result and summary generation now run through tested Go
  helpers in cmd/actionhelper instead of large inline workflow scripts.
• The hosted external-wave workflow now runs those helper commands from the
  checked-out source module, fixing the post-#278 working-directory
  regression on GitHub-hosted runners.

Documentation

• Published a dated current-main hosted-wave verification note and committed
  aggregate summary artifact for the post-hardening rerun after the helper-path
  repair.

Verification

• go run ./cmd/releasehelper verify-compat
• go run ./cmd/releasehelper notes --version v0.4.2 --out .tmp/release-notes-v0.4.2.md

Upgrade Notes

Summary

• v0.4.2 is a patch release that carries the latest hosted external-wave
  hardening work into the public release surface.
• Hosted wave result and summary generation now flow through tested Go helpers
  rather than large inline workflow scripts.
• The release also fixes the helper working-directory regression that was
  exposed when that extraction was first revalidated on GitHub-hosted runners.

Operator Action

• If you pin the first-party GitHub Action, move the tag from @v0.4.1 to
  @v0.4.2 so hosted lanes pick up the repaired helper invocation path.
• If you maintain your own hosted external-wave workflow around
  .github/workflows/external-action-wave.yml, re-read the current helper-path
  assumptions before copying older snippets or partial steps.
• If you review hosted-wave evidence, prefer the new dated current-main note
  and committed aggregate summary when checking whether the latest hosted path
  still produces stable denominator health and actionable-yield signal.

Rollback

• Reinstall v0.4.1 if this patch causes rollout friction and you need to
  return quickly to the prior public release.
• If rolling back from hosted-wave workflows, also restore any automation or
  documentation that assumes the repaired helper working-directory behavior.
• Keep the rollback within the same install family where possible:
  • go install github.com/cervantesh/cervo-mutants/cmd/cervomut@v0.4.1
  • reinstall the v0.4.1 GitHub release archive
