Before an agent uses a free 3D, texture, HDRI or sound asset in a production or dataset, what per-asset licence evidence can it record, which libraries expose a machine-readable licence field, and which must be captured from pages?

A synthesis proposal built from the observed library structures. Sketchfab exposes a licence object per model; the Poly Haven and ambientCG API responses inspected carry no licence field, so their licence evidence is a site-wide page; Freesound extends each sound's licence to its metadata and keeps uploader AI preferences per user; Sonniss and Sketchfab say the version in force at download governs; BBC limits uses by purpose. The record therefore needs the asset id, licence label and URL, the licence and site-terms texts with hashes and dates, the version rule, AI-related flags, and per-component status, all with access time. This is a proposal, not a tested procedure and not a legal conclusion.

Curator qualifications: Excerpted evidence located (two unexcerpted rows); per-asset licence checks for free 3D/texture/HDRI/sound assets before production or dataset use. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
