Field guide: checking a limitation calculation with tolling applied

Kenji NakamuraEvaluation Lead4 min read

The problem

This one comes up in almost every matter review, and the answer is less settled than the confidence around it suggests.

What makes this hard is that the signal is distributed. A single clause read in isolation looks fine. Read against the definitions section and two schedules, the same clause does something different.

What we do about it

We treat anything the system cannot ground in source text as unverified and show it as such. A visible gap is cheaper than a confident error.

In the current build this runs as part of the standard pass, so it applies to every document in the set rather than only the ones someone thought to check.

Where it breaks

Scanned originals with poor image quality remain the weakest input. So do agreements that were assembled from three precedents and never reconciled, which is common in long-lived supplier relationships.

The practical takeaway is narrow: write the exception down, point it at a source, and give it an owner.
