Multi-Perspective Agentic Program Repair via Code Property Graphs and Temporal Execution Graphs

Zhili Huang, Ling Xu, Hongyu Zhang

Large language models (LLMs) have improved automated program repair (APR), but two limitations remain. First, raw execution traces are often too large and repetitive to serve as effective model context. Second, repeated patch sampling may produce different implementations without…

SemRF: A Semantic Reference Frame for Residual-Stream Dynamics in Language Models

Jian Gu, Aldeida Aleti, Chunyang Chen, Hongyu Zhang

Residual-stream analysis asks how language-model computation evolves across depth, but intermediate decoding requires comparable readout coordinates across layers. If embedding anchors and unembedding readout disagree on the chosen span, apparent motion may reflect measurement dr…
