Decide if 3 agreeing AI tools may auto-merge

Your team wants AI in its pull request flow for a TypeScript product. One tool drafts code from a ticket, a second reviews the diff, and a third writes tests. A teammate proposes chaining them with no person in between. If the reviewer approves and the generated tests pass, the PR merges itself.

Do you approve the pipeline? Decide where people stay in the loop, and what, if anything, may merge without one.
