**Status:** First-party illustrative assignment composite; not customer, production, randomized-trial, benchmark, or independently audited data  
**Run date:** 2026-08-23  
**Evidence checked:** 2026-08-31  
**Operator:** InfiniSynapse Data Team  
**Attestor:** William Zhu, InfiniSynapse cofounder ([GitHub @allwefantasy](https://github.com/allwefantasy))

The operator inspected an illustrative 35-day pack: 72,400 users split 50.2%/49.8%, a 1.6-point checkout delta, a 0.5-point refund delta, and three unplanned dashboard looks. The interval was held as exploratory, and shipping remained held for peeking plus the adverse refund line.

The [CSV](https://infinisynapse.com/blog-media/what-is-ab-testing/downloads/peek-summary-WIABT-LOOKS-20260823.csv) exposes six aggregates and two held items. The [verification script](https://infinisynapse.com/blog-media/what-is-ab-testing/downloads/verify-WIABT-LOOKS-20260823.py) checks displayed output only. Rows, SQL, intervals, look timestamps, stopping rule, SRM, and metric definitions are unavailable.
