Clinical Coding Review Agent

Reported events and medications arrive as free text and must be coded to standard dictionaries, and doing it by hand is slow and inconsistent between coders. This agent proposes a dictionary code for each new term by matching it to the dictionary and to how similar terms were coded before in the study. It marks a code as clear only when there is a single strong match. Close matches with more than one option, and terms that match nothing, go to a human coder with a drafted query where the verbatim term is vague. It then checks that the same term is coded the same way across the whole study and flags conflicts. It never finalizes a code on its own. You approve all codes and queries. Edge case: a term that could mean two very different events always goes to a human.
