A cross-problem reference to open datasets used across Open Problem Lab problem packs. Every entry here is or should be documented in the relevant pack's datasets.md and evidence.json.
This file is maintained as a discovery aid. It is not canonical — the canonical dataset record lives in the problem pack. When a dataset is accepted into a pack, update the pack's datasets.md and evidence.json, then update this index.

Dataset Quality Requirements
Before a dataset is accepted into a problem pack's evidence.json, it must have:
Verified URL with permanent or archived access
Source date and access date
Geographic grain documented
Case definition or variable definitions documented
License or reuse permission documented
Known limitations listed
Denominator source (where applicable)
Use pnpm verify:sources to check URL availability after adding or modifying evidence records.
Add the dataset to the relevant pack's datasets.md with source, grain, status, and intended use.
Add an evidence.json record with URL, date, method, and limitations.
Update this file under the appropriate category.
Run pnpm validate and pnpm verify:sources.
