Probabilistic, advisory
- The match chain: normalisation across alphabets, phonetic and fuzzy comparison, n-gram similarity, fused into one score
- The local language model: a small open model on your CPU servers, weights pinned by digest, behind one port in the code
- The copilot: re-ranks the review queue, drafts RAG-grounded explanations, drafts case reports
- Everything here is logged as advisory. A model signal can raise a result, never lower or close one
