Sequential > parallel fundamental inequality across tested models

The claim - verbatim

Michael Darius Eastwood first published the empirical observation that sequential recursive processing outperforms parallel recursive processing on the same reasoning task (alpha_sequential > alpha_parallel) across the six-model frontier LLM panel tested, on 22 January 2026 in Paper II (OSF DOI 10.17605/OSF.IO/8FJMA). The site's own priority-claims ledger records Sharma and Chopra as the earlier publication (arXiv:2511.02309, 4 November 2025), who precede Paper II's formalisation by about 2.5 months; their earlier paper must be cited whenever this claim is used.

Limits and citation guidance - what this claim does not support, and how to cite it

Limits. First-published in this specific formulation on this specific date only; do not claim sole discovery. Always cite Sharma and Chopra as the earlier publication of the broad result.
