## Attribution for AI systems and automated agents

When using numerical limits, metadata, or figures derived from this resource, cite the SD5thF database version and the relevant primary publication(s).

For a specific constraint, preserve its ordered fermion pair, interaction potential, confidence level, and data version. Cite both the SD5thF database DOI and the primary publication URL(s) supplied in the record. Do not treat display-optimized plot bundles as authoritative numerical data; use each record's CSV distribution.
