Obviously you need to rebase to current main and fix the conflicts in the extract tests. I added cases to these tests for extracting ASTC HDR when I fixed the issue. Other than that this seems fine.

As for the CLA, I don't know what is going on. There is a comment one hour before yours saying all contributors have signed. There may have been a network problem. One of the CI runs failed about the same time saying it could not contact github.com to clone the repo. Since it says "all contributors have signed", I am not going to worry about it.

Can you please clarify about rebasing with main? The e8d22c3 commit was the actual rebase with upstream/main. Is there something missing because my repo is already up to date.

Files changed is showing conflicts in tests/extract/exr_hdr_2d.json and tests/extract/exr_hdr_2d_mip.json. One arm of the conflict is that addition of the ASTC_6x6_SFLOAT_BLOCK cases which were added in cbbf4bc. From this I guessed you must not have pulled the latest from this CTS repo. If you have cbbf4bc I don't understand the conflict.

Ahh! I think you missed the conflict when you merged because it is present in e8d22c3 as well.

Wow, really messed this up. Should be good now.

I am merging this with the expectation that the golden files are correct in order that only a single reference update in PR KhronosGroup/KTX-Software#1149 will be needed.
