Benchmark: redline generation against a firm playbook
The problem
Every review team we work with has a version of this problem. Redline generation against a firm playbook rarely announces itself.
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 score against a human baseline drawn from executed matters rather than a synthetic set, because synthetic contracts do not contain the drafting scars that cause real misses.
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.
