Treating Agent Reasoning as a Span (forestmars.substack.com via hn)
AI Agents Run To Completion Treating reasoning as infrastructure is collapsing the stack The Agentic Web has two requirements that have to work simultaneously: trust and observability. Trust without observability is recklessness.
Large Language Models (LLMs) achieve strong performance on reasoning tasks, but whether this reflects faithful logical inference or heuristic approximation remains unclear. We study this question in legal entailment by comparing three para…
