"""probe_tables.py TABLES [--limit 200] - retrieval-only check of engram tables on the AA-Omniscience dev sample (10-20,
PLAN-verticals): for each item, retrieve over TABLES (comma list) and over wiki alone; per domain, the share of items whose
gold answer string appears in the top 3 / top 10 passages (a proxy: AA answers are short, exact strings). Same hash-ordered,
domain round-robin sample as engram_eval.py --limit. Run before any LLM time; a table that does not raise answer@10 for its
domain is not worth an eval. Env as engram.py (THREADS, NPROBE, NCAND)."""
