• definitions 2026-09-06 — see /method for what each field means
• schemaVersion 2

number.json is reproducible from the partitions in this archive:

python pipeline/recompute.py --data-dir data --check

The figures were computed under the definitions current on the date in the tag.
Definitions move, and when they do the changelog on /method records it, so a
figure from an older snapshot is read against that date's definitions, not today's.
