Northwind Financial: 79% of summaries were substantially rewritten, with edits clustering in two clauses the agent consistently misread.

The problem
A contract-summary agent reported a 98% completion rate for two quarters. Legal operations quietly disagreed.
What we did
Assembly instrumented the full workflow — instruction, retrieved scope, tool calls, and what paralegals did with the output.
The result
79% of summaries were substantially rewritten, with edits clustering in two clauses the agent consistently misread. Fixed in a fortnight, once visible.
Every dashboard said the agent was working. The paralegals knew otherwise and nobody asked them.
