What was already known
Known categoricity-transfer theorems commonly require additional structural hypotheses or address narrower classes.
What changed and why it matters
Advances the stated target relative to the recorded baseline.
The AI contribution
OpenAI attributes the manuscript to its internal model; individual human contributions remain unspecified.
Limitations
This is qualitative eventual categoricity; no numerical threshold is supplied. The CH threshold companion conflicts with a published claim and is held pending. Its formal artifact is not evidence for this qualitative theorem. Preprint. AIProofWatch read the source statement and context; it has not refereed the proof, compiled a formal development, or established community acceptance.
Verification evidence
Evidence labels show what supports the claim. Importance rates its impact if correct.
Author claim
The original source reports this scoped result; AIProofWatch reviewed its statement, not the full proof.
Accessible artifact / proof
A research manuscript or proof artifact is publicly accessible; availability is not independent checking.
