“The hardest and most consequential work are the simulations and the evals in addition to the test pipeline. We need to test whether the rewritten software preserves the behavior customers depend on, performs under real conditions, and handles failures correctly. The agents can iterate, but passing those comprehensive evals has to be a prerequisite for deployment.”

Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-11-04).
Found in Patel's post. The four sentences match exactly, ending "prerequisite for deployment." The post continues with a sentence about reliability, which the passage does not include.
