Assessment

Why?

Strongest counted support: The primary study reports a smaller crown-area-to-stem-diameter ratio in drought-exposed trees. weight 2.000000 evidence

Suppressed as dependent: The quoted passage directly reports approximately 26.5% smaller crown area per unit stem diameter in drought-exposed trees than untreated controls.

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.

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.
