This manuscript presents an original and intellectually stimulating hypothesis: that host defense against Mycobacterium tuberculosis has evolved through an adaptive compromise, in which intermediate neutrophil abundance and NOX2-derived reactive oxygen species (ROS) provide greater protection than maximal neutrophil responses.The integration of human genetics, neutrophil biology, host-pathogen coevolution, and tuberculosis immunopathogenesis yields a coherent conceptual framework that is both novel and potentially impactful.The manuscript is generally well written and logically organized, and it proposes several experimentally testable predictions, which considerably strengthen its value as a hypothesis article.Overall, I found the hypothesis scienti cally interesting and worthy of publication.However, several key aspects should be revised to distinguish established evidence from interpretation and speculation better.Most of my concerns do not question the originality of the hypothesis itself, but rather the strength with which some conclusions are presented.Major Comments 1. Clearly distinguish hypothesis from established evidence My primary concern is that, throughout the manuscript, speculative interpretations are sometimes presented with a level of certainty that exceeds the available evidence.For example, the proposed Ushaped relationship between neutrophil activity and tuberculosis susceptibility is presented as the central biological model of the manuscript.Although this is an attractive and plausible hypothesis, it has Qeios
