These changes look fine but Chimera-AV1-10bit-480x270.avif is missing a Primary Item (pitm) box. I always thought that was required. MIAF section 7.3.2 says that a primary item is required for files that are conformant with any of the MIAF profiles. I thought this requirement carried over to AVIF as well. Do you have a different understanding?

Yup, you're correct. I have updated the file to add a 'pitm' box.
