-- Deep-dive universe (rubric v15, gate 25): the top-N eligible companies by
-- market cap (descending), deterministic. The screening-flag promotion that
-- gate 3 allows is handled by Python at assignment time, NOT by this SQL, so
-- the SQL respects the assignment-time rule and never reads opinions.
-- Null-safe: marketcap is filtered to > 0 so the SELECT market_cap column is
-- never null.
