"known_limitations": [
"The SDK licence page does not define the small-scale threshold; it is in the Proprietary Software License Agreement (Section 1.22) and a help page (dated 2019/06/21), so thresholds come from three pages that were checked separately.",
"A 20 million yen annual-sales trigger appears for VTuber tracking software; it is a product-specific rule and conflicts at first glance with the 10 million yen definition.",
"The English agreement says Japanese text prevails in interpretation; the Japanese page and agreement were not compared line by line.",
"Agreement sections about Expandable Applications and fee amounts beyond the tier names were not read; fee amounts are on separate plan pages.",
"Cubism SDK components may be under separate licences (Open Software licence for samples, proprietary Core); the SDK about page lists both agreements but does not map them to files."
