Stage 3: independently tested.
The rule that placed itSomeone other than the maker has tested it: an independent benchmark, a peer-reviewed paper, or a hands-on test by a trusted outlet.
The evidenceMETR's study of public records found maths results have come faster in 2026, including three open problems solved with AI, but no clear speed-up in improvements to algorithms. It calls the evidence from solved open problems weak. METR, Have We Seen an Acceleration in Discoveries?, Aug 14, 2026.

Not found in our sources yet: what the makers claim; what has launched; tested with real people; how many people use it. No regulator approves AI for this task, so the approval step doesn't apply.
Track record and tools.
Failures and court cases are shown beside the stage, never folded into it. Tools are listed because the evidence names them, in no order of merit.
