Reviewers have raised findings against it on FOUR separate PRs (#19, #35, #40, #48), always the same two shapes: - - - it asserts a test result without carrying the command or its output ("all merged and tested", "three tests pass") - - it cites a file that is not in the delivered tree (`ops/TARGET.md`) - -Those are cheap findings that cost a review round trip each time, and they recur because nothing checks the file.

The kernel's dispatch, lease, and claim machinery is real and tested. The worker side of the protocol is unimplemented - nothing in this repo can execute an agent step.
