[Copilot]

🟡 Changes recommended

The workflows’ LATEST_VERSION env values weren’t updated to match the new matrix entries, so the “latest” conditional steps will run against the wrong versions.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

.github/workflows/test-opentofu.yml:66

• The OpenTofu matrix now includes 1.12., but env.LATEST_VERSION is still 1.10.. This means the workflow will treat 1.10.* as “latest” (running the go-test-action step) and will not treat 1.12.* as the latest version.

        if: ${{ matrix.opentofu != env.LATEST_VERSION }}
