Netflix's Open Content page says its open source content is available under CC BY 4.0, but the per-title licence files for the Chimera AV1 encodes (Sept 2019) and the Meridian IMP/VDM/Atmos assets (Nov 2016) license those sequences under CC BY-NC-ND 4.0, and the AV1 readme says each asset's licence is in its own license.txt; the TechblogAssets Sparks licence file referenced by the README returns 404.

Curator qualifications: Conflict preserved: page-level CC BY 4.0 vs title-level CC BY-NC-ND 4.0; the texts do not state precedence. Use the more restrictive title licence for those titles. Sparks/Experimental AV1 licence files and av2ctc/IMF listings (E3, E4, E6, E7) not reinspected. Text only; no media downloaded. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary.

Limitations: Live bucket and page. [component_reuse_restriction] Treat Chimera and Meridian as non-commercial, no-derivatives; no derived fixtures from them.

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