What happened: GPT-5.4 Pro reportedly solved Erdős Problem #1196 in around eighty minutes, with a LaTeX write-up in thirty. Terence Tao engaged substantively in the problem forum, characterising the contribution's novelty in two ways: recognition of a bridge between a standard process in the anatomy-of-integers literature and a known duality, and a sustained tactical commitment to staying on the integers where prior literature defaulted to transport to the reals.
Diagnostic reading: a worked example of recombination-within-configured-space producing a result humans had not found — with the field's most authoritative living commentator supplying, in real time, the vocabulary problem Thread 2 tracks: is "bridge-recognition plus tactical persistence" insight, or search? The question is not answerable by inspecting the output, which is ARG-03's point run in the empirical direction. Tao's own flagged open thread (a weight naturally defined on the reals in an integer-side argument — "I'm not sure what to make of this fact yet") marks the register the log aims to preserve on both sides.
Formal verification status pending at capture; not citable as empirical evidence until verification lands. Tao's comments supplied directly from the forum thread; automated retrieval blocked.
