SHEAF
Frontier Extension to Heterogeneous Agents
Key result
Sheaf diagnostic maintains R² > 0.96 at all scales; best baseline degrades from 0.83 (n=5) to 0.52 (n=50)
Falsification
A non-topological diagnostic that maintains accuracy at scale, or a counterexample to the Laplacian-Cohomology Bridge
Abstract
Extends diagnostics to heterogeneous agents with different observation spaces, vocabularies, and objectives. Introduces a topology auction mechanism for resolving impossibility.
