# Desk log HTAB-KEYS-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 pack with 54,800 normalized assignment rows, 1,200 dual-key collisions, a 0.8-point checkout delta, and 0.2 additional support contacts per 1,000. The SQL was described but not published; shipping remained held because collisions were undiagnosed.

The [CSV](https://infinisynapse.com/blog-media/how-to-ab-test/downloads/join-summary-HTAB-KEYS-20260823.csv) exposes four aggregates and two held items. The [verification script](https://infinisynapse.com/blog-media/how-to-ab-test/downloads/verify-HTAB-KEYS-20260823.py) checks displayed output only. Rows, key mapping, SQL, intervals, SRM, guardrail definitions, and collision adjudication are unavailable.
