"description": "CS9 fixed-mapping condition v1. All 20 aliases are invented strings with zero surface relation to any table name (no shared 2/3/4-char prefix, no substring match). Fixes the cs8 abbreviation confound. T1: 3-char single-token (rare-word tokens, fid 22k-95k). T2: 4-char two-token with 2+2 BPE split (2-char first tokens, fid 933-54k).",
"motivation": "CS8 aliases (cust, dept, emp, etc.) are common SQL abbreviations of their assigned table names. A surface-matching heuristic can predict them without any learned commitment, inflating the rand model's geometry silhouette above zero. CS9 aliases have no such relation.",
