The lookup-table insert relied on INSERT OR IGNORE and the unique index to dedupe against existing rows, but SQLite unique indexes treat NULLs as distinct - extracting a second table into the same lookup table re-inserted every NULL-containing value, growing orphan rows on each extract. The insert now also has an IS-based NOT EXISTS guard, matching how the foreign keys themselves are resolved.
