**Status.** derived

This node is assembled mechanically from the 2 claims that carry the concept tag `structure`. It is a roster of what the corpus says under this term.

## Every claim under this term

2 claims across 2 works, 2021 to 2026.

**2021**

- [3782191-032](https://wulfkaal.github.io/claims/3782191-032) [mechanism/argued] -- Concentration produces instability and dispersion produces stability: the more concentrated a structure is, the more unstable it is, because little changes can cause major structural change, while a spread out pattern remains spread out when disturbed.

**2026**

- [7598518-029](https://wulfkaal.github.io/claims/7598518-029) [design/stated] -- Three validator families share a mean accuracy of 0.75 while differing in structure: one is homogeneous at 0.75, one has each validator reliable at 0.90 on two hash-drawn tags and at 0.60 on the other two so that domain-scoped reputation has something to find, and one has five validators at 0.90 and fifteen at 0.70, a competent minority.
  > Intelligence models increasingly learn from data that earlier Intelligence models produced, and when that loop repeats the rare cases disappear first. This paper preregisters a test of whether a reputation-weighted validator pool, filtering the training data of a recursive replacement loop, keeps those rare cases alive. The outcomes remain sealed until a replication of the original model-collapse result succeeds.
