The claim - verbatim

Michael Darius Eastwood first published experimental validation of the ARC Principle across a panel of frontier AI models (Claude, DeepSeek, Gemini, Grok, Groq Qwen, GPT) on 22 January 2026 in Paper II: 'The ARC Principle - Experimental Validation of Super-Linear Error Suppression Through Sequential Recursive Processing' under OSF DOI 10.17605/OSF.IO/6C5XB (sister DOI 10.17605/OSF.IO/8FJMA). The standalone 'sequential > parallel' priority is credited by the site's own ledger as CONCURRENT with Sharma and Chopra (arXiv:2511.02309, 4 November 2025), who precede Paper II's formalisation by about 2.5 months.
