QGTCD Constraints Note

This corrected preprint presents its research question, method, bounded result, and principal limitations in a standardized reader-facing format. Quantum Gradient Time Crystal Dilation (QGTCD) proposes that unequal temporal opportunity can bias otherwise symmetric microscopic transitions and thereby contribute to gravitational behavior. A bounded companion model turns that narrative into positive normalized Markov kernels, proves a smooth-lattice drift-diffusion limit, and constructs a conditional position-velocity calibration . This technical companion note asks a different question: which stronger gravity conclusions do not follow from those premises? It converts five limitations already exposed by the companion's constructive analysis into explicit countermodel certificates and a premise-dependency audit. It does not claim five independent discoveries. It belongs to the Super Information Theory, Super Dark Time, and QGTCD physics research program.
