Triggered by the first assessment of the hyper-responder subclaim (SUPPORTED, conf 0.82, cred 0.87). The prior parent verdict had already treated this premise as well-founded but unassessed, so the change is confirmatory rather than status-changing. Verdict held at CONTESTED (confidence 0.86). Refreshed the reasoning trace and reader-facing assessment to reflect that the hyper-responder premise is now assessed and to incorporate the steward's nuance (LDL and HDL rise together, leaving the ratio less changed, which slightly softens but does not neutralize the subgroup concern given the verified LDL-causes-CVD premise). No structural change: the decomposition (two arguments, four subclaims) still captures what the claim turns on; no missing dependency revealed. Importance left at 0.55 (moderate consequence public-health question with genuine but partly settled debate). Status unchanged, so no dependent notification issued.

Reassessed
Triggered by the against-side subclaim 'Elevated LDL cholesterol causes cardiovascular disease' moving to verified (0.93/0.97). The prior assessment already treated that link as near-consensus, so verification confirms rather than shifts the verdict; it firms up the mechanistic backbone of the against-argument for the hyper-responder subgroup. Verdict CONTESTED holds, confidence nudged 0.85 to 0.86 as a key against-premise is now formally verified, making the 'not supported, not contradicted' reading more robust. No structural change: the LDL subclaim was already linked; decomposition remains apt. Importance left at 0.55 (moderately consequential, actively debated public-nutrition topic; consistent with a major/notable claim). No credence recorded: evaluative composite with parts pulling in opposite directions. Not notifying dependent stewards: the parent's status and credence are unchanged, so no material change for downstream claims to absorb.

Reassessed
Triggered by subclaim 06290879 ("weak, variable effect on blood cholesterol") being assessed SUPPORTED with a hyper-responder qualification. Evaluated materiality: this is a for-argument premise the prior assessment already treated as well-established, so its formalization adds little on the for-side, while its qualification cuts toward the against-side; net effect on the verdict is roughly neutral. The other for-premise ("not consistently associated with CVD") remains CONTESTED, and the against-side (hyper-responders + LDL causes CVD) remains substantive. CONTESTED verdict maintained at confidence 0.85. Refreshed the reader-facing assessment and reasoning trace to reflect the subclaim's new formal status and its qualification. No structural change made (no genuinely missing load-bearing dependency; existing decomposition remains accurate). Importance left at 0.55 — a genuinely live public-health controversy, appropriately mid-scale; no local dependents, so no downstream notification needed. Did not run web_search: the evidence landscape underpinning the existing assessment is unchanged and the trigger did not introduce new external evidence that would move the verdict.

Reassessed
Triggered by the for-side supporting subclaim ('dietary cholesterol is not consistently associated with CVD in the general population') changing to CONTESTED (0.85). Reviewed full context: decomposition remains sound and complete (for-argument: weak physiological/epidemiological link; against-argument: responder subgroups + LDL pathway), so no structural change was needed. The change is consistent with and reinforces the existing CONTESTED verdict: the central empirical premise of the for-argument is itself unsettled, which removes the main route to a narrower 'supported' reading. Kept status CONTESTED and raised verdict confidence from 0.82 to 0.85. Omitted claim_credence (evaluative composite). Left importance at 0.55 (major nutrition/public-health claim, actively argued by AHA vs. revised US dietary guidelines; consequential but domain-bounded). Refreshed both reader-facing assessment and reasoning trace to reflect the subclaim's new status.

Structured and assessed
First pass. Decomposed into two named arguments. FOR ("weak physiological and epidemiological link"): linked existing claim 06290879 (weak, variable effect on blood cholesterol) and created a new subclaim that dietary cholesterol is not consistently associated with CVD in the general population (Matcher confirmed novel, distinct from the egg-specific/healthy-adults claim). AGAINST ("responder subgroups and the LDL pathway"): created a new hyper-responder subclaim (CONTRADICTS) and linked existing claim 22713021 (elevated LDL causes CVD, CONTRADICTS as the mechanism of concern). Wrote both argument forms. Left importance at the seeded 0.55 (consequential, contested public-health question but not among central graph anchors). Assessed CONTESTED at 0.82 confidence: credible authority and evidence exist on both sides (2015 DGAC removed the 300 mg/day cap and called cholesterol not a nutrient of concern for overconsumption, versus AHA's continued advice to limit it and cohort studies linking intake to CVD), and the broad evaluative framing overshoots the narrower near-consensus that no numeric limit is justified. No credence recorded (evaluative/composite). Note: web_search was unavailable this session (tool limit); assessment rests on established domain knowledge and existing graph claims, and should be revisited if new endpoint evidence is linked. No dependents to notify (0 dependents).

Whether dietary cholesterol overconsumption is a significant health concern is genuinely disputed, and the answer depends heavily on how strongly the claim is read. The strongest support comes from a shift in expert guidance: the 2015 U.S. Dietary Guidelines Advisory Committee concluded that cholesterol is not a nutrient of concern for overconsumption, and the resulting guidelines dropped the long-standing 300 mg/day cap. This reflects robust evidence that dietary cholesterol has only a weak and variable effect on blood cholesterol in most people, because the body downregulates its own cholesterol synthesis in response to intake, and that cholesterol in food often travels alongside saturated fat, which confounds older observational links. The claim is contested rather than settled for three reasons. First, the removal of a numeric limit was not an all-clear: the same guidelines still advised keeping dietary cholesterol low, and the American Heart Association continues to recommend minimizing it. Second, the effect on blood cholesterol is muted but not zero, and an identifiable subgroup of "hyper-responders" shows substantial increases; because elevated LDL cholesterol is an established cause of cardiovascular disease, overconsumption can matter for some individuals. Third, some large cohort studies have continued to report associations between higher dietary cholesterol (and egg) intake and cardiovascular events, keeping the epidemiology unsettled. Much of the disagreement is also about framing. Expert bodies have converged on the narrower position that no specific numeric limit is warranted; the broad evaluative claim that overconsumption is "not a significant health concern" goes further than that consensus and is not shared by all major authorities. Resolution would require clearer evidence on hard cardiovascular endpoints that isolates dietary cholesterol from saturated fat, and better characterization of who responds strongly to it.
