Claim
Direct correlation spectroscopy reported a relative frequency agreement of −2.4×10⁻¹⁹ with ±5.7×10⁻¹⁹ statistical and ±1.0×10⁻¹⁹ systematic uncertainties.

Assessment
Supported
Main unresolved issue: 2 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:e4b026cb-37a4-8995-ab83-58dc1fb48c28
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 arxiv.org was not found on the page when Galedra fetched it.
Why?
Strongest counted support: The abstract reports direct correlation-spectroscopy agreement with separate statistical and systematic uncertainties. weight 2.000000 evidence
Suppressed as dependent: The excerpt directly reports −2.4×10⁻¹⁹ agreement with ±5.7×10⁻¹⁹ statistical and ±1.0×10⁻¹⁹ systematic uncertainties.
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.

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.
