# Research with primary sources

Question: [question]. Relevant date or date range: [date]. Audience and decision: [context].

Use primary documentation and original data where available. If browsing is unavailable, work from the supplied documents and state the freshness limit. Read the relevant source page; do not treat a search snippet as full evidence.

For each material claim record the supporting URL, publication or update date when shown, and what the source establishes. Separate facts from your inference and identify unresolved disagreement.

Return a concise answer, a comparison table when useful, and the few limitations that change the decision. Link each claim to its supporting source. Do not invent citations or fill missing measurements with estimates presented as facts.
