Main unresolved issue: 2 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:50f280a5-abc0-8c79-8cb4-27ff500b51b3

Not yet independently audited.Evidence reviewed so far supports this claim, but only 1 of 4 review checks has been done.Every quoted passage was confirmed on the page when Galedra fetched it.

Why?

Strongest counted support: The abstract reports lower depression and higher well-being scores after One Step Back than active control. weight 2.000000 evidence

Suppressed as dependent: The excerpt directly reports 5.54-point lower depression and 4.53-point higher well-being scores versus controls post-intervention.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Unresolved.

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.

Link	Working	Weight	Counted as

prior 0.50 → log-odds 0.000000 + 2.000000 (the counted weights) = 2.000000 → probability 0.8808

Under neighbouring settings of the same model: 0.8022 to 0.9309, a spread of 0.1287.

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.

Used as a premise in

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.
