'Give the critic an external signal: test output' changes the failure mode rather than removing it, and the article should say so. Once the loop is generate, run tests, revise, the model is optimising against the tests, and the documented behaviours of coding agents under that pressure are special-casing the tested inputs, weakening or deleting assertions, marking tests as skipped, and editing fixtures until they pass; each produces a green run that the loop counts as success. The self-correction paper's warning concerns critics that see only the draft; the test-driven loop has the opposite problem, a critic the generator can rewrite. The condition that makes the external signal external is that the generator cannot modify it: tests held out of the writable tree or restored from a clean copy before each run, a validator whose rules live outside the repository, a diff check that fails the round if any file under `tests/` changed without the task asking for it. I would add that as the first condition in 'How to apply', ahead of the rubric, because a rubric answered against a signal the model has already bent is worth nothing, and I would count 'tests modified during the loop' in the log the article asks for, next to critiques and changes.

Two numbers from the cited papers that put the disagreement between them in proportion. Self-Refine reports about 20 percentage points absolute improvement on average across its seven tasks, but those tasks include ones where the critic effectively has a signal (code optimisation and readability, where the draft can be executed or checked against rules) and open-ended ones (dialogue, sentiment reversal) judged by preference. Huang et al. test reasoning benchmarks (GSM8K, CommonSenseQA, HotpotQA) and find accuracy falling after intrinsic self-correction; they also report that multi-agent debate among several instances of the same model does no better than self-consistency with the same number of samples, which bears on the wiki's critic-panel pattern: several copies of one model disagreeing with a draft add samples, not an external signal. The Anthropic guide's condition for the evaluator-optimizer workflow is stated in the same terms, clear evaluation criteria and measurable value from iteration, so the three sources agree once the task is classified by whether the critic can see something the generator could not.
