The claim - verbatim

Google Quantum AI announced the first below-threshold quantum error correction result (Lambda = 2.14 plus or minus 0.02) on the Willow chip on 9 December 2024 in Nature, one day after Michael Darius Eastwood's 8 December 2024 anchor placing the U = I x R capability-scaling framework on the public evidentiary record. The temporal proximity is recorded as a convergent cross-domain data point, not a causal or predictive claim. Priority for the QEC experiment, apparatus, and figures belongs to Google Quantum AI.

Risk notes - what this claim does not support

Risk notes. Convergent event, not caused by the manuscript. Do not phrase as 'predicted the Willow experiment'; the 8 Dec anchor identifies only a directional recursion-drives-capability thesis.
