…o headless example Two fixes to docs/knuckle.md: 1. Add ISO verification step in the installation walkthrough. Release ISOs are cosign-signed via GitHub Actions OIDC keyless signing. Users who want to verify authenticity before writing to USB now have the exact command inline, with a note that the SECURITY.md in the knuckle repo has full details. 2. Add update_strategy field to the minimal headless install example. The field is optional (defaults to "reboot") but omitting it from the docs example was inconsistent with the knuckle README and could leave users unaware that Flatcar update behavior is configurable. Now the minimal example is explicit about this important setting. Signed-off-by: guide <guide-agent@hive.local>

What
Two improvements to
docs/knuckle.md, the end-user page for Knuckle at docs.projectbluefin.io/knuckle.Changes
1. Cosign ISO verification step
Adds a step 2 to the ISO installation walkthrough explaining how to verify the downloaded ISO with cosign before writing it to USB. Every release ISO is signed with GitHub Actions OIDC keyless signing; users previously had no inline guidance for this and needed to find
SECURITY.mdin the knuckle repo.The command is taken directly from knuckle's
docs/SECURITY.md(the authoritative source), adapted for the ISO artifact.2.
update_strategyin minimal headless exampleThe minimal
install.jsonexample was missingupdate_strategy. The field defaults to"reboot"so the omission is not a bug, but:No changes to site configuration, navigation, or other pages.
