/**
 * v2.15.0 follow-up — G5: QA business-perspective review state.
 *
 * Similar in shape to G1 (slice review) but lives on the QA side and
 * uses the 6-item business checklist from the 12 Gaps positioning
 * memory. Technical verification (coverage / P99 / security scan) is
 * AI auto-decided in `peaks-rd`'s fan-out; QA only records what the
 * user (business / product reviewer) sees.
 *
 * Persistence: `.peaks/_runtime/<sid>/qa-business-reviews/<rid>.json`.
 *
 *   6 items: business-flow / req-coverage / boundary-cases / ui-assembly /
 *            exception-tone / mergeable
 *   decision: pending | accepted | rejected
 *   threshold: avg >= 3 AND no item <= 2 (same as G1)
