confluence-explain-doc

Write and publish a Confluence page (or Jira/report text) that explains a bug's cause, logic, and fix so a first-time reader understands it. Code-capture first: real source lines with red/green/blue line highlights and line-numbered captions, one section per problem, how problems connect, git blame plus the original reason for each cause, details folded. Use for "write this up in Confluence", "explain the root cause", "I don't understand this explanation", "progressive disclosure", 컨플 정리, 설명 문서, 원인 설명.
