 ## Current Focus: Phase 29ao（CorePlan composition）
 
-Next: Phase 29ao P21（Pattern1 subset: body is step-only）
-指示書: `docs/development/current/main/phases/phase-29ao/P21-PATTERN1-SUBSET-BODY-IS-STEP-ONLY-INSTRUCTIONS.md`
+Next: Phase 29ao P22（TBD）
+指示書: TBD
 運用ルール: integration filter で phase143_* は回さない（JoinIR 回帰は phase29ae pack のみ）
 運用ルール: phase286_pattern9_* は legacy pack (SKIP) を使う
