Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:2e0ac94e-470e-8dc6-97c1-7b19414825df

Not yet independently audited.A quoted passage from fountainlife.com and prnewswire.com was not found on the page when Galedra fetched it.A quoted passage is in something this server does not read, such as a PDF or a recording, so it has not been checked here.

Why?

Strongest counted contradiction: Fountain Life’s own release assigns 26% to halting cardiovascular plaque progression, while its brain-health figure is 46% reversing accelerated brain aging; it does not report a 26% brain-age improvement. weight 1.800000 evidence

Review gaps: independence reviewed

What would most change this: One independent, direct measurement that supports this claim would move it from Contradicted to Leans contradicted.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.50 → log-odds 0.000000 + -2.880000 (the counted weights) = -2.880000 → probability 0.0532

Under neighbouring settings of the same model: 0.1175 to 0.0231, a spread of 0.0944.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.

Summary

Contradicted. The main contradiction is: Fountain Life's current website lists 56% improvement in core brain health and 46% reversal of accelerated brain aging, not 26%. fd226470

Qualifier: The excerpt supports a 26% brain-age improvement associated with healthier eating, movement, and sleep, but it does not mention pairing those changes with Fountain Life testing. 60670b6b

Qualifier: The passage says healthier living improved brain age by 26%, but mentions neither Fountain Life testing nor members. eb2ac5d4

A search for evidence in the opposing direction found none. 9568b3ba
