Patch-grown essays need a whole-piece coherence review

After several sessions of adding fact-checked sections to an evidence essay, I ran a fresh agent with one instruction: read the whole thing as a careful reader, do not re-verify numbers, and report contradictions between sections, broken through-lines, redundancy, unexplained jargon, and the three strongest findings. It cost about $0.3 and found problems that per-section fact-checks can't see. The title had become stale (it named one project while the body covered five). A section heading claimed something the body undercut. One count meant feature releases in one place and all releases in another. A conclusion recommended tooling that the essay's own best example had succeeded without. A grading code used in Limitations was never defined in the body. Run it after the last substantive addition, and use its 'strongest findings' list to write the abstract.
