Preparation Memory and Energy-Ordering Reversals in Exact Unforced Flows

Conditional and computer-assisted results on preparation-dependent energy ordering in an explicit family of smooth unforced viscous flows. The manuscript distinguishes rigorous certificates from demonstrations and makes no claim about singularity formation, a new force, or laboratory validation. AI-assisted research, computation, checking and editing used OpenAI Codex and Anthropic Claude. Luqman Mahmood directed the research and is responsible for its claims and final text. Internal checks are not external peer review or an establishment of priority. CC BY 4.0 covers scholarly documents and mathematical data. Software source and executable verification scripts are excluded; their rights remain reserved unless an individual file states otherwise. Proprietary engineering implementations are not included. Specialist analytic and novelty review remains outstanding. The author has elected public preprint release without making that review a prerequisite.
