From Agent Traces to Trust: Evidence Tracing and Execution Provenance in LLM Agents
Announce Type: new Abstract: Large language model (LLM)-based agents increasingly solve complex tasks by interacting with external tools, retrieval systems, memory modules, environments, and other agents. These capabilities expand agent autonomy, but also make agent behavior harder to verify, debug, and audit. Final-answer accuracy alone cannot explain how an output was produced, which evidence supported each claim, whether tool calls were justified, how memory influenced later decisions, or...
Insights Generator: Systematic Corpus-Level Trace Diagnostics for LLM Agents
arXiv:2605.21347v3 Announce Type: replace Abstract: Diagnosing failures in LLM agents remains largely manual. Practitioners inspect a small subset of execution traces, form ad-hoc hypotheses, and iterate. This process misses patterns that only emerge across trace populations and does not scale to production corpora where individual traces span tens of thousands of tokens.
Ebola 'spreading unchecked for months' as patient zero traced back to January
Ebola 'spreading unchecked for months' as patient zero traced back to January Health care workers in Africa have just admitted patient zero zero could be traced back to Janurary, months earlier than previously thought, in the eastern DRC village of Rwampara Ebola may have been running rampant in the Democratic Republic of Congo (DRC) since January, with local officials tracing the latest outbreak of the killer virus back to a patient zero at the turn of the year. But, for some reason, that...
Compress-Distill: Reasoning Trace Compression for Efficient Knowledge Distillation
arXiv:2606.05988v1 Announce Type: new Abstract: Reasoning models produce long chain-of-thought traces that are costly to distill and encourage verbose student outputs. We study post-hoc compression of such traces before knowledge distillation.
ZX-Calculus:Trace-Indexed Dependent Types and Epistemic Semantics
Announce Type: new Abstract: We propose ZX-Calculus (Knowledge Evolution Calculus), a conservative extension of Martin-Lof Dependent Type Theory (MLTT) integrating trace-indexed types, presheaf non-monotone semantics, and constructive AGM belief revision. A Coq mechanisation accompanies the paper (34 complete proofs; zero admits for the two central results). FinTrace(s0,sn) is an inductive family of typed execution traces.
Reasoning Arena: Trace Tournaments When Verifiable Rewards Fall Short
arXiv:2606.09380v1 Announce Type: new Abstract: Reinforcement learning with verifiable rewards (RLVR) has become a leading paradigm for improving the reasoning ability of large language models through outcome-based supervision. However, verifiable rewards frequently become uninformative at the group level: when all sampled traces of a given prompt receive identical rewards, group-relative advantage estimation provides no gradient signal, even though the traces may differ substantially in...
ReasoningFlow: Discourse Structures for Understanding LLM Reasoning Traces
arXiv:2606.05402v1 Announce Type: new Abstract: Large reasoning models (LRMs) produce reasoning traces with non-linear structures, such as backtracking and self-correction, that complicate the evaluation and monitoring of the reasoning process. We introduce ReasoningFlow, a framework that captures the discourse structures of LRM reasoning traces into fine-grained directed acyclic graphs (DAGs).
Expert-Aware Causal Tracing of Factual Recall in Sparse MoE Language Models
new Abstract: Causal tracing of factual recall has been studied predominantly in dense transformer language models, where interventions localize information flow to layers or feed-forward modules. Sparse mixture-of-experts (MoE) language models introduce a sharper question: when a factual prediction is mediated by a routed MoE block, which routed expert contributions matter? We formulate expert-aware causal tracing for sparse MoE language models.
Trace-Preserving hp Interpolation and Polynomial Liftings on Conforming Hexahedral Meshes
Announce Type: new Abstract: Trace-compatible polynomial extensions are a recurring local ingredient in high-order finite element analysis on conforming hexahedral meshes. They are needed whenever prescribed edge and face traces must be preserved while a polynomial is extended into a neighboring cell or boundary patch. The main contribution of this paper is the construction of p-robust polynomial liftings on nonsingular conforming hexahedral boundary patches, with stable control of both the...
Trace Reconstruction with Language Models
Announce Type: replace Abstract: The general trace reconstruction problem seeks to recover an original sequence from its noisy copies independently corrupted by insertions, deletions, and substitutions. This problem arises in applications such as DNA data storage, a promising storage medium due to its high information density and longevity. However, errors introduced during DNA synthesis, storage, and sequencing require correction through algorithms and codes, with trace reconstruction often...
