• Requires Domain Model Change - Bugs reveal domain understanding gap
  • Reasoning: [Why domain model change is needed]
  • Impact: [What domain concepts need updating]
• Requires Architectural Change - Bugs indicate pattern failure
  • Reasoning: [Why architectural change is needed]
  • ADR Required: [Yes/No] - [If yes, what decision needs documenting]
• Needs More Investigation - Missing information
  • What’s Missing: [What information is needed]
