 The pairs are matched before implementation on repository, primary implementation language, scope, and expected review surface. Pair 1 changes operational/compliance documentation without runtime behavior; pair 2 changes agent-key lifecycle across the API and UI; pair 3 adds medium asynchronous notification delivery across backend jobs and consumer-facing interfaces; pair 4 adds compliance evidence across stored invocation data, exports, mapping data, and PDF surfaces. If implementation discovery makes a pair materially unequal or blocked, stop before the first timed review and record a new frozen protocol revision rather than silently substituting an issue.
