For a Sketchfab model, which document governs what I may do (the per-model Creative Commons label, the Standard or Editorial licence, or the Terms of Use), and how do the NoAI and CreatedWithAI labels bear on use in a production or an AI dataset?

Sketchfab layers three documents: a per-model licence label exposed by the API (seven CC types plus free-st, st, ed), the paid Standard/Editorial licence agreement, and Terms of Use effective 12 August 2026 that bar using NoAI-tagged content in generative-AI datasets and say the licence in force at download governs. Sketchfab's own 2023 blog says the NoAI tag may not bind outside the platform for CC-licensed models. The API objects inspected show no NoAI field, and the licence agreement page text read has no NoAI clause although the blog says Standard-licensed downloads are contractually covered; these gaps are for curation. Curator qualifications: 13 of 13 excerpts present. Negatives re-run: licences page 'NoAI' 0, 'generative' 0 (one 'AI' hit is the site navigation category 'AI Generated'); swagger.json 0 for noai/no_ai/createdWithAI; model object has no AI-related key. Terms: 'NoAI' 7 occurrences, effective 'August 12, 2026'. Operator conflict strengthened: the licences page itself defines 'Sketchfab is a division of Epic Games, Inc.' while its footer reads '© 2026, KitBash SF Operations LLC. All rights reserved.' 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: [rights_conflict_record] Rights conflicts preserved: blog vs licence text on NoAI; operator naming (Epic division vs KitBash SF Operations LLC) within one page and across pages. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
