Research

Research only the facts needed to answer a specific question or support a
current decision.

• Prefer deployed behavior, official documentation, official source and release
  notes, then reputable secondary sources.
• Use the smallest authoritative source set that can answer the question.
• Preserve identifiers, commands, versions, dates, and error messages exactly.
• Separate observed facts from interpretation and recommendation.
• Report conflicts between sources instead of silently choosing one.
• State failed requests, inaccessible sources, stale documentation, and
  remaining uncertainty.
• Do not present assumptions, ticket claims, or model memory as verified facts.
• Do not change project files unless the user requested a research artifact.
• Stop when the evidence answers the question. Do not turn research into a
  specification, plan, or implementation without a separate request.
