Benchmark: lease abstraction on scanned originals
The problem
We keep coming back to lease abstraction on scanned originals, because the cost of a miss here compounds across a portfolio.
Volume changes the shape of the problem. At ten documents you can hold the exceptions in your head. At four hundred you need the exceptions written down and checkable.
How we measured 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.
None of this removes the reviewer. It moves the reviewer to the part of the work where judgement actually pays.
