A reserved value nobody can discover is a trap, and this is the view the API's /categories endpoint is built from. Emitted for the two flow vocabularies only -- cog_balances() returns a stock and has no concept to sum within. Also fix test-categories.R to exclude pseudo-category rows from crosswalk-specific assertions (one row per (category, subtype) pair, non-empty item_codes, valid subtypes).
