Every legal team has a set of positions: what it will accept on limitation of liability, which governing laws are fine, where it needs a carve-out, what triggers escalation to the general counsel. In most organisations this exists partly in a template, partly in precedent, and substantially in the heads of two or three people.
Extracting that into an explicit, versioned playbook is most of the work in a contract-review deployment, and it is work with value independent of any AI system — teams commonly discover during it that their stated position and their actual practice have diverged. The model then compares an incoming contract against it and reports differences.
Framed this way, the task becomes tractable and evaluable. “Is this contract risky?” is unanswerable and unmeasurable. “Does clause 12 depart from position 7, and how?” has a right answer that a lawyer can confirm or reject, which means you can build an evaluation set and know whether the thing works.
