Last dual-run — harness snapshot only

File sparco-dual-run-parity-20260910T133058Z.json · captured 2026-09-10T13:30:58Z · 10/10 PASS (failed=0) — harness SoR, not live traffic.

How to read this page

Honest constraints: Modern p95 is worse than legacy (outside +20% band). Do not pitch p95 win. No live SPARCO latency theater on this page. Re-run dual-run and refresh this embedded snapshot to update numbers. Legacy Admin login stays on :80 — this page is not that portal.
