 1. Investigate codebase. _Isolate deep exploration in sub-agents/tasks where available. To prevent context snowballing, instruct subagents to give you distilled summaries only._

+3. Self-review against READY FOR DEVELOPMENT standard. If the intent derives from a parent artifact (epic plan, PRD, story brief), verify that every requirement assigned to this scope has a corresponding AC — architectural mechanisms do not substitute for testable acceptance criteria.
 4. If intent gaps exist, do not fantasize, do not leave open questions, HALT and ask the human.
