+# Phase 29aj P9: Isolate phase286 pattern9 legacy integration (docs/smokes)
+
+Date: 2025-12-29  
+Status: Ready for execution  
+Scope: smokes/docs の整理のみ（挙動コードは触らない）  
+Goal: JoinIR 回帰ゲートを phase29ae pack に固定し、phase286_pattern9_* を legacy/skip に隔離する
+
+## Objective
+
+- phase286_pattern9_frag_poc の plugins disabled 経路 mismatch を “legacy” として SSOT 化
+- JoinIR 回帰は `phase29ae_regression_pack_vm.sh` のみに固定
+- 任意の integration filter 実行で誤爆しないように legacy pack を用意する
+
+## Non-goals
+
+- phase286_pattern9_frag_poc の挙動修正
+- 新 env var / 新ログ追加
+- JoinIR 本体の挙動変更
+
+## Implementation Steps
+
+### Step 1: legacy pack を追加
+
+New:
+- `tools/smokes/v2/profiles/integration/joinir/phase286_pattern9_legacy_pack.sh`
+
+Behavior:
+- `phase286_pattern9_frag_poc` を `test_skip` で固定
+- skip 理由を 1 行で明記（plugins disabled path mismatch）
+
+### Step 2: docs に SSOT を追記
+
+Update:
+- `docs/development/current/main/phases/phase-29aj/README.md`
+- `docs/development/current/main/phases/phase-29ae/README.md`
+- `docs/development/current/main/10-Now.md`
+- `docs/development/current/main/30-Backlog.md`
+- `CURRENT_TASK.md`
+
+## Verification
+
+- `./tools/smokes/v2/run.sh --profile quick`
+- `./tools/smokes/v2/profiles/integration/joinir/phase29ae_regression_pack_vm.sh`
+- `./tools/smokes/v2/profiles/integration/joinir/phase286_pattern9_legacy_pack.sh` (SKIP)
+
+## Commit
+
+- `git add -A && git commit -m "docs(phase29aj): isolate phase286 pattern9 legacy smoke"`
