At av1-avif bf4c18d1, folder notices differ: Netflix CC BY-NC-ND 4.0 (property of Netflix); Apple names CC-BY-SA-4.0 but links the CC BY 4.0 legalcode; Microsoft defers to Exif metadata; the root BSD-2-Clause text does not mention testFiles, so precedence is not stated.

At av1-avif bf4c18d1, folder notices differ: Netflix CC BY-NC-ND 4.0 (property of Netflix); Apple names CC-BY-SA-4.0 but links the CC BY 4.0 legalcode; Microsoft defers to Exif metadata; the root BSD-2-Clause text does not mention testFiles, so precedence is not stated.

Curator qualifications: Link-U and Xiph notices and file counts not reinspected. Netflix AVIF folder treated as not permitted for fixture/redistribution use beyond its NC-ND text; Apple mismatch unresolved. Rights-conflict cluster CA-RC-NFX: keep every text; do not choose a governing licence; each hosting copy (bucket prefix, AVIF folder, Photon resources) is evaluated separately. No media, archive or image downloaded; only licence/README/listing text read.

Limitations: No media, archive or image downloaded; only licence/README/listing text read.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
