Assessment

Leans supported

Score: 0.7991 under ledger-default@0.3.0 at snapshot 27745

3 of 4 review checks done · 1 counted · 2 by the author only

1 independent evidence lineage · review checks 1 of 4 · stability LOW

Main unresolved issue: 2 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:d88d26b3-d2e8-825a-a747-a7d8f1c26528

Not yet independently audited.This assessment depends heavily on modeling choices.

Why?

Strongest counted support: The primary study reports SnOx suppression of interface reactivity and 95.7% retained minimodule performance after 1000 thermal cycles. weight 2.000000 evidence

Suppressed as dependent: The passage directly states that an ultrathin conformal SnOx interlayer suppresses interfacial reactivity between nickel oxide and perovskite.

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 Leans supported 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 0.35 → log-odds -0.619039 + 2.000000 (the counted weights) = 1.380961 → probability 0.7991

Under neighbouring settings of the same model: 0.6859 to 0.8788, a spread of 0.1929.

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.
