Structure Identification and Compression Behavior Analysis of 3D Fibrous Networks via Persistent Homology

Three-dimensional fibrous networks combine high porosity with a characteristic nonlinear J-shaped compressive response, yet the topological origins of this stiffening behavior remain elusive due to the complexity of their random architecture. Here we investigate the structural me...

Measuring Reverse-Specification Quality Without Ground Truth: A Three-Layer Framework and a Pre-Registered Study of Scale-Induced Failure Modes in Autonomous Coding Agents

Tool-using LLM coding agents can reverse-generate specifications from source, but the quality of those specifications is hard to assess when no reference specification exists. We present a ground-truth-free, deterministic-first framework that measures three layers - inventory cov...
