Why: O2 I1 is implemented in Agent-Native #48 and needs user stage 6 review before merge. Evidence: Worker attempt 2 success at 899fd70; host vet and tests (with -race) pass; PR #48 CI success; independent review PASS with no blocking issues. Impact: Task card and review package only; Agent-Native #48 stays draft until stage 6 approval. Refs: Agent-Native#48, Agent-System-Dev#639 Co-authored-by: Cursor <cursoragent@cursor.com>
