The Expect-CT header is deprecated. This header was used to enforce Certificate Transparency (CT) requirements, but it is no longer recommended for use. Chromium-based browsers, such as Google Chrome, deprecated the Expect-CT header starting from version 107, as they now enforce CT by default

How can I customize these reviews?

Check out the Hyperlint AI Reviewer docs for more information on how to customize the review.

If you just want to ignore it on this PR, you can add the hyperlint-ignore label to the PR. Future changes won't trigger a Hyperlint review.

Note specifically for link checks, we only check the first 30 links in a file and we cache the results for several hours (for instance, if you just added a page, you might experience this). Our recommendation is to add hyperlint-ignore to the PR to ignore the link check for this PR.

Hello @ratesangelo
Thank you for the heads up. I've shared this information internally.
However, the "Add security headers" Managed Transform, when enabled, still adds the header, so we will keep the documentation as is for now.
