The full 2×101 qx table lives in src/lib/facts-mortality.ts, GENERATED deterministically by scripts/generate_mortality_facts.py from the NCHS source workbooks (strict structural parse with invariants, no manual transcription). Promoted 2026-08-28 (delegated): the workbooks were re-downloaded and the generator re-run — output byte-identical to the committed file.
