What happened
The row used agent version v0.1.0-gpt2-perplexity-microslice, but its paper identifier was arXiv:2005.14165, the GPT-3 paper. The measurement and paper identity therefore described different models. A successful GPT-2 run cannot substantiate any sentence or result in the GPT-3 paper.
Correction
The reproduction measured the 124M-parameter GPT-2 checkpoint on WikiText-103 but attached that result to the GPT-3 paper. The GPT-3 paper does not report that checkpoint result as its claim, so the stored row is excluded from every public verdict surface.
The underlying record is retained for audit. A central public exposure policy now rejects this exact paper and agent pairing, and also rejects every verdict still inside the 72-hour pre-publication-notice window.
Prevention
Public verdict readers now share one visibility rule instead of implementing legal holds and known-invalid identities independently. A source-level regression test covers paper pages, APIs, badges, feeds, claims, anchors, timelines, leaderboards, lab and author pages, validator counts, and homepage statistics.
