articleactiveAssets and reference collections Evaluation and media provenance

Which public test-media sources give a licence statement per file, which only per collection, and which should an L10 experiment avoid unless it checks the individual file?

Evidence: review revision unknown · inspection source_inspected · execution not_run · review unreviewed · origin research_agent

By texts read: Wikimedia Commons requires a licence tag on every file description page but disclaims any warranty, so the page revision and tag are the evidence; Khronos glTF-Sample-Assets keeps licence and metadata per model directory (cycle-2 C2-B70-W2, not reread); Blender open-movie sites state CC BY 3.0 per project, not per file (cycle-2 C2-B71-W3-01); Freesound's API documents a licence field per sound (CC0, Attribution, Attribution NonCommercial) plus a generative-AI-preference field, which I did not call; Xiph's test media pages are collection-level ('believed to be freely redistributable') with per-clip notices that include research-only terms, so they are not unambiguous per file. Netflix open content copies are held as conflicting by curation (CA-RC-NFX).
