Structured and assessed
First pass (structure_and_assess). Reviewed context: claim had one supporting subclaim (variable intestinal cholesterol absorption efficiency), no instances, no prior assessment, and one dependent (the hyper-responder subset claim, currently supported, which cites this as a support). Searched the graph for genetic-determinants and responder claims; the only related nodes are the hyper-responder claim, the weak/variable-effect claim, and the synthesis-suppression claim, all already present. No genetic-response subclaim exists, but I chose not to mint one: the claim is simple and settled, and the existing absorption-variability mechanistic support plus the direct feeding-study evidence are sufficient (avoided over-decomposition per §6/§2). Left decomposition as-is; kept canonical form (14 words, neutral, frame-independent). Set importance to 0.32 with contestation 0.15: a notable supporting premise in the dietary-cholesterol debate but the variability phenomenon itself is uncontested. Web-searched current feeding-study literature (Fernandez-group syntheses of ~166 studies, egg-feeding crossover trials): the hyper/hypo-responder classification (~2.2 mg/dL per 100 mg/day threshold; ~1/3 hyper-responders) directly demonstrates marked variability. Assessed VERIFIED, confidence 0.85, credence 0.92, marginal_yield 0.10. Single natural line of support, so no named argument created.

The blood-cholesterol response to a given intake of dietary cholesterol differs markedly from one person to the next, and this variability is well established rather than disputed. Controlled feeding studies conducted over several decades consistently find a wide distribution of responses, and this pattern is durable enough to have produced a standard operational classification: individuals whose total cholesterol rises by more than about 2.2 mg/dL for each additional 100 mg/day of dietary cholesterol are termed "hyper-responders," and those below that threshold "hypo-responders," with roughly a third of people falling in the hyper-responder group. In egg-feeding trials, hyper-responders show significant rises in LDL and HDL cholesterol while hypo-responders show essentially none, a direct demonstration that the same dietary stimulus produces very different blood responses across people. Part of this variability is mechanistic: people differ substantially in how efficiently the intestine absorbs cholesterol, and differences in the compensatory suppression of the body's own cholesterol synthesis further modulate the net effect. The variability itself is not what the broader dietary-cholesterol debate turns on; that debate concerns the clinical significance of the response and whether dietary cholesterol independently affects cardiovascular risk. The existence of marked inter-individual variability is a settled input to those larger questions, not one of the contested cruxes.
