# Desk log ABM-SRM-20260823

**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 CMS pack: 61,000 users split 51.2%/48.8%, a 2.1-point add-to-cart delta, and a 180 ms p95 latency increase. SQL was declared after the green badge. The decision remained held for undiagnosed SRM and latency.

The [CSV](https://infinisynapse.com/blog-media/ab-testing-meaning/downloads/meaning-summary-ABM-SRM-20260823.csv) exposes five aggregates and two held items. The [verification script](https://infinisynapse.com/blog-media/ab-testing-meaning/downloads/verify-ABM-SRM-20260823.py) checks displayed output only. Assignment/outcome rows, expected allocation, SRM result, intervals, variances, code, stopping rule, and latency distribution are unavailable.
