Strict Repeaters Project

Who dominates the strict U.S.-nexus backlog?

A standalone public project on the strict U.S.-nexus proxy core, showing that the regulated-looking backlog remains spread across NIH-linked, academic, and industry sponsors rather than collapsing into one archetype.

Project

This page stays inside the strict U.S.-nexus core and asks who still dominates once the proxy core is read as a repeater problem rather than a sector average.

The strict-core backlog is smaller than the full registry backlog, but it is still institutionally distributed and far from clean.

The strict proxy does not strip away the repeater structure.
