Endpoint–Lindelöf Local Bounds via Explicit Short Truncation of the Zeta Function

A method to bound the size of the Riemann zeta function on short intervals using a one-sided truncation with explicit endpoint constants, removing the need for dual Dirichlet sums.

A large language model was used to assist with symbolic derivations and drafting text. Mathematical correctness is not guaranteed; this document represents exploratory AI-assisted research. This upload is part of an experiment on whether large language models can produce research-level mathematical content under guided direction. Expert feedback and verification (positive or negative) are welcome and will be incorporated into future revisions.
