Claim

At 80 bar, the study measured CU-6 gravimetric methane uptakes of up to 0.67 g g−1 at 273 K and 0.53 g g−1 at 298 K for CU-6-Fe.

Assessment

Supported

Score: 0.9781 under ledger-default@0.3.0 at snapshot 27745

1 of 4 review checks done · 1 counted

2 independent evidence lineages · review checks 1 of 4 · stability HIGH

Main unresolved issue: 3 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:d3f7f163-31b0-8e3b-8550-b36a9fe6786c

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

Why?

Strongest counted support: The primary study reports methane uptake values across three temperatures. weight 2.000000 evidence

Suppressed as dependent: The excerpt directly reports CU-6-Fe methane uptakes of 0.67 g/g at 273 K and 0.53 g/g at 298 K under 80 bar.

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 Supported.

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 + 3.800000 (the counted weights) = 3.800000 → probability 0.9781

Under neighbouring settings of the same model: 0.9346 to 0.9929, a spread of 0.0583.

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.

Inferences

Concluded from

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.
