Round 2

One saved weekly assessment of The proton's partial lifetime for positron–neutral-pion decay is below 10^35 years., kept as it was published. It is an estimate from three models reading the evidence, not proof the hypothesis holds, and it did not set any price.

The round note and its sources

Round 2: score 0.27

Live panel did not return all three estimates (OpenAI, Anthropic, xAI failed or gave an unusable answer). A round is only live when all three are valid, so this round is a placeholder at the previous score rather than an average of two.

Audit bundle

No audit bundle is recorded for this round. A bundle from another round is not substituted for it.
