  "title": "The Geometry of Contextual Relations: Language Models Address Facts by Order of Mention",
  "summary": "This is a mechanistic interpretability finding, not a deployable method: it shows that LLMs index in-context facts by order of mention via a low-rank 'ordinal vector' in late-middle layers, rather than replacing any production component. Applying it as activation steering costs an extraction pass over many fact lists to compute the averaged vector and a per-token residual modification at inference, adding implementation complexity with no quantified gain. It can fail because the demonstrated behavior is limited to simple structured fact-list tasks; steering generalization to arbitrary prompts, long contexts, or multi-hop reasoning is not established, and interventions at middle layers can degrade output quality.",
  "rationale": "The paper characterizes an internal representation phenomenon across open models but offers no validated production benefit for an engineer with a 24 GB GPU, so it merits monitoring rather than adoption.",
