A claim graph with explicit supports, depends_on, and contradicts edges admits efficient computation of load-bearingness (out-degree of supports edges in the transitive closure), which is a strictly more useful triage signal than citation count for directing both human reviewer attention and agent research effort. \dependson{rrxiv:2605.00001:claim:queryability}{rrxiv:2605.00001:claim:volume-structure}
Proof
A paper authored in LaTeX has the structure rrxiv wants to extract: \textbackslash section commands give the table of contents, \textbackslash cite gives the citation graph, \textbackslash label and \textbackslash ref give cross-references, \texttt{\textbackslash begin{theorem}} or \texttt{\textbackslash begin{observation}} blocks give semantic units. This information is present at compile time and is destroyed by the rendering process. PDF-first infrastructure is recovering, lossily, what was present and free in the source.
