Summary

The v0.6.0 tag's docker job (CI) failed in Set up job:

Unable to resolve action `sigstore/cosign-installer@v4`, unable to find version `v4`

The Release workflow waits for CI on the tagged commit, so it stopped too. Neither the v0.6.0 image nor the GitHub release was published; the website deployed.

sigstore/cosign-installer has published only full version tags since v4 (v4.1.2; there is no v4), and only tag-only jobs use it, so #158's PR checks never resolved it. This pins @v4.1.2 in ci.yml and release.yml; Dependabot can bump full versions.

Checks

  • Every uses: ref in the workflows now resolves (checked through the GitHub API). ruby/setup-ruby@v1 is a branch, which the website run used successfully.
  • cosign-installer v4.1.2 installing the pinned Cosign v2.6.3 was replayed locally, following the installer's own verification: the release key's digest matches, and Cosign v3.0.6 verifies the v2.6.3 binary's signature.
  • AGENTS.md notes the exception, and to check that a ref exists before bumping it.

The v0.6.0 tag's docker and release jobs failed in Set up job: 'Unable to
resolve action sigstore/cosign-installer@v4, unable to find version v4'.
cosign-installer publishes full version tags only since v4, and only
tag-only jobs use it, so the bump's PR checks never resolved it. Every
other action ref in the workflows resolves. AGENTS.md notes the
exception and to check that a ref exists before bumping it.

0.6.1 carries 0.6.0's code. The v0.6.0 tag's workflows asked for
sigstore/cosign-installer@v4, which does not exist, so its image,
signatures and GitHub release were never published; ideaconnect#159 pins v4.1.2.
The v0.6.0 tag stays as it is, marked in the CHANGELOG as not published.
Tag this commit as v0.6.1.
