Breaking the Chain: A Causal Analysis of LLM Faithfulness to Intermediate Structures

arXiv:2603.16475v2 Announce Type: replace Abstract: In schema-guided reasoning (SGR) pipelines, LLMs produce explicit intermediate structures -- rubrics, checklists, or verification queries -- before committing to a final decision. SGR is increasingly adopted because it promises controllability: practitioners expect to inspect, edit, and override these structures to steer the outcome. But does the promise hold? We introduce a causal evaluation protocol to measure it: by selecting tasks where a deterministic function maps intermediate structures to decisions, every controlled edit implies a uni

Why this matters
Why now

The rapid advancement and deployment of LLMs necessitate robust methods for ensuring their reliability and controllability, especially in critical applications.

Why it’s important

A strategic reader should care because this research addresses fundamental reliability and controllability issues with LLMs, which are crucial for their safe and effective integration into complex workflows.

What changes

This causal evaluation protocol introduces a new standard for assessing LLM faithfulness to intermediate structures, providing a clearer path to verifiable and auditable AI systems.
