  "mechanism": "The substrate-level primitive of 'try the same call again after a delay.' ReAttempt is the atomic physical-substrate operation: same arguments, same target, after a pause. Distinct from {{retry}}, which is the strategic Mind-layer pattern that classifies failures, consults failure history, computes adaptive {{backoff}}, and decides whether conditions have changed enough to warrant another attempt. Descendants build classification and budget on top of ReAttempt; the primitive imposes no ceiling.",
