Assessment

Why?

Strongest counted support: A university-hosted abstract reports the same conditional diffusion model and 41% and 15% policy cost-effectiveness improvements for central-offtaker targeting. weight 1.800000 evidence

Suppressed as dependent: The model reports up to 41% cost-effectiveness improvement in a controlled setting and 15% under a European Hydrogen Bank-style auction.

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.

• Independent reporting repeats the 13–15% auction-style and up-to-41% idealised modeled improvements while noting the idealised scenario removed real-world constraints.

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.
