{"version":"1.0","effective_date":"2026-10-12","summary":"The repository preserves differing source values with their attribution, dates, geography, units, definitions and verification limits. A difference is not by itself proof that either source is wrong. Analyses that need one value disclose the selected basis, the alternatives and the reason for selection.","rules":["Compare the same measure, period, geographic footprint, unit, definition and method before describing values as conflicting. Otherwise label them as not directly comparable.","Never hide or average a value solely because another source differs. Preserve publisher wording separately from portal interpretation and from unverified legacy entries.","For an analysis requiring one value, prefer the most reliable source suitable for that question: relevant primary authority, traceable original issue, applicable time/geography and documented method. A high publisher grade alone is insufficient.","Show all alternatives alongside the analytical basis and selection rationale. If no defensible preference exists, report the range or scenarios and do not manufacture a single estimate.","Repository users can choose their own basis. A portal analytical selection does not declare another source false; official national warnings remain the operational reference.","Missing, withdrawn or user-transcribed material is labelled explicitly. Removal from the active repository does not erase dated archives or reuse old evidence IDs."]}
