## Retrieval rules

1. Resolve canonical pattern or study-set URLs before citing a record.
2. Preserve language, source, provenance, and dataset version.
3. Prefer reviewed and canonical records over migration or legacy aliases.
4. Treat generated practice material as learning support, not linguistic authority.
5. Keep translations and cross-language transfers explicit; do not infer equivalence without the published relation.
