Control the brief-to-article handoff starts with a clearly stated operating decision for a bounded audience. Record the question, scope, time period, definitions, exclusions, and owner before collecting evidence.
Five handoff fields, question, audience, scope, sources, and owner, should match before release. This is an operating-control measure for the article workflow, not a claim about market performance. Use it to make the handoff inspectable and to show where judgment remains.
Use authoritative sources and map each material claim to the exact page that supports it. Keep dates, units, calculations, assumptions, and limitations visible; if a reviewer cannot reproduce the reasoning, narrow or remove the claim.
Close the handoff with the validation result, three related Research links, and the next owner action. Preserve Blog and Research inventories separately, stage only intended Research files, and record repository evidence at the GitHub-only boundary.
