{
  "context": "Cold round-2 production admin gateway baseline versus selective round-3 candidate on one static real-data clone. Ten sequential pairs alternate AB/BA. Each SQL operation uses clone-only search_path and RR; explicit candidate transactions preserve their single-snapshot semantics. TeachingCourseCategory and CourseTeachingProfile Parse reads/schema lookups are prefetched and shared within each pair OUTSIDE service timers. Service time also excludes setup, cache clearing, authentication and transport; pairRequestMs includes those per-pair prefetches/clears and transport for BOTH variants. This is not full API user-experience timing. ReviewRewardIncome is frozen as an equivalent copied-row view. All clone result caches are emptied before and after every variant. Digest readiness is stubbed for an unchanged copied digest: no source-write/trigger acceptance is claimed. Operator-bound manager projection, not manager-login acceptance.",
