P23-02 diagnostic projection scopes r343-r03
Diagnostic-only native wall-time scopes on the unchanged r340-r02 candidate. Thread-local POD counters across ephemeral cores. One cold646 tick, full original oracle equality and owned exit; inclusive scopes overlap and may perturb timing. No pure CPU, subtraction-based attribution, stable performance, release adoption or unit acceptance. Failed preparation and rejected r02 retained. All gzip bytes verified; originals retained.
