Claim

The study reported that reef-building coral microbiomes had biosynthetic potential rivaling or surpassing traditional natural-product sources such as sponges.

Assessment

Leans supported

Score: 0.7790 under ledger-default@0.3.0 at snapshot 27745

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

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

Main unresolved issue: 4 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:21616710-2f15-8bd3-8b99-89947ad6ef87

Not yet independently audited.Evidence points both ways.Every quoted passage was confirmed on the page when Galedra fetched it.

Why?

Strongest counted support: The primary study compares coral microbiome biosynthetic potential favorably with sponge natural-product sources. weight 1.800000 evidence

Strongest counted contradiction: Raw recovery yielded fewer biosynthetic gene-cluster families from corals than sponges, though normalization reversed the comparison. weight 0.540000 evidence

Suppressed as dependent: The quoted passage directly says reef-building coral microbiomes rivalled or surpassed traditional natural-product sources such as sponges.; The primary study compares coral microbiome biosynthetic potential with established natural-product sources.

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 0.50 → log-odds 0.000000 + 1.260000 (the counted weights) = 1.260000 → probability 0.7790

Under neighbouring settings of the same model: 0.7072 to 0.8373, a spread of 0.1301.

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.

Evidence against

Raw recovery yielded fewer biosynthetic gene-cluster families from corals than sponges, though normalization reversed the comparison.

This qualifies and partly contradicts an unqualified claim of coral microbiome potential rivaling or surpassing sponges; the result depends on normalization.

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.

Summary

Leans supported. The main support is: The primary study compares coral microbiome biosynthetic potential favorably with sponge natural-product sources. fd1b9677

Against that, contradiction: Raw recovery yielded fewer biosynthetic gene-cluster families from corals than sponges, though normalization reversed the comparison. 49bae959

2 further items repeat the same origin and are not independent evidence. af93c9c8c88f2df3
