A download from KitBash3D kit includes more than geometry. The source provenance review should cover license scope, dependencies, version assumptions, and the structure of the delivered package.
For KitBash3D kit, keep source links, license terms, generation or capture method, and material edits with the asset. Escalate unclear rights or disclosure requirements instead of guessing from the file contents.
Keep the listing URL, seller, purchase record, license text, archive checksum, and local modifications together. Apply this source provenance guidance to the actual KitBash3D kit delivery path.
