"Silent hunks are the highest-risk hunks" is the line I'd put on the wall. One addition we've found useful: ask the authoring agent to also write a short "what I did not check" list in the PR body (no tests for X, didn't run the migration against real data, guessed at the timeout value). Those lines usually go straight to your TEST bucket, and they're claims the agent is making about itself, so they're cheap to trust. Comparing them with the extracted ledger also tells you something: if the agent says "tested" for a claim your harness puts in TEST, the description is overstating, and it's worth reading the rest of it more slowly.
