The same original file verifies fine on openai.com/research/verify with both SynthID and Content Credentials detected.\n\nIs ChatGPT’s upload pipeline intentionally sanitizing/removing C2PA chunks, and is openai.com/verify the intended/only supported way to verify provenance? Or is there a way to preserve/read the original uploaded file metadata inside a chat?\n\nThe image in question is:\n\nwhat ChatGPT says he sees:\n\nand what the openai.com/research/verify website sees:",
