+# Phase 29aj P5: Pattern5 infinite early-exit planner-first via Facts (subset)
+
+Date: 2025-12-29  
+Status: Ready for execution  
+Scope: Pattern5 facts → planner candidate → single_planner planner-first（仕様不変）  
+Goal: Pattern5 を Facts→Planner に乗せ、extractor 依存を 1 本減らす
+
+## Objective
+
+- Pattern5（loop(true) + early exit）を Facts→Planner 経路に追加
+- single_planner は Pattern5 の型一致時のみ planner-first 採用
+- 既定挙動・観測・エラー文字列は不変
+
+## Non-goals
+
+- Pattern5 サブセット拡張（複数exit/複雑条件/複数carrier）
+- ルール順序 SSOT の CandidateSet 移管
+- 新 env var / 新ログ追加
+
+## Implementation Steps
+
+### Step 1: Facts SSOT 追加（Pattern5）
+
+Files:
+- `src/mir/builder/control_flow/plan/facts/pattern5_infinite_early_exit_facts.rs` (new)
+
+Facts:
+- `Pattern5InfiniteEarlyExitFacts { loop_var, exit_kind, exit_condition, exit_value, carrier_var, carrier_update, loop_increment }`
+
+Extraction rules (Ok(None) fallback only):
+- condition は `loop(true)` のみ
+- body 先頭が `if (cond) { return <expr> }` か `if (cond) { break }`（else 無し）
+- then_body は単一要素のみ（Return / Break のみ）
+- Break 版は carrier 1 個だけ許可し、`var = var + ...` 形のみ
+- loop_increment は `extract_loop_increment_plan(body, loop_var)` が取れる場合のみ
+
+Unit tests:
+- return 版 / break 版の success
+- else 付き / increment 無し → Ok(None)
+
+### Step 2: LoopFacts に接続
+
+Files:
+- `src/mir/builder/control_flow/plan/facts/mod.rs`
+- `src/mir/builder/control_flow/plan/facts/loop_facts.rs`
+
+Changes:
+- LoopFacts に `pattern5_infinite_early_exit` を追加
+- `try_build_loop_facts()` に抽出を追加
+- all-none 判定に `pattern5_infinite_early_exit` を含める
+
+### Step 3: Planner candidate 追加
+
+File:
+- `src/mir/builder/control_flow/plan/planner/build.rs`
+
+Changes:
+- facts が Some のとき `DomainPlan::Pattern5InfiniteEarlyExit` を候補に追加
+- rule 名は `loop/pattern5_infinite_early_exit`
+- unit test 追加
+
+### Step 4: single_planner を Pattern5 planner-first に
+
+File:
+- `src/mir/builder/control_flow/plan/single_planner/rules.rs`
+
+Changes:
+- RuleKind::Pattern5 を追加
+- planner_opt が `Pattern5InfiniteEarlyExit` のとき採用
+- それ以外は extractor へフォールバック
+
+### Step 5: docs / CURRENT_TASK 更新
+
+Files:
+- `docs/development/current/main/phases/phase-29aj/README.md`
+- `docs/development/current/main/10-Now.md`
+- `docs/development/current/main/30-Backlog.md`
+- `CURRENT_TASK.md`
+
+## Acceptance Criteria
+
+- `cargo build --release`
+- `./tools/smokes/v2/run.sh --profile quick`
+- `./tools/smokes/v2/profiles/integration/joinir/phase29ae_regression_pack_vm.sh`
+- `./tools/smokes/v2/run.sh --profile integration --filter "phase143_"`
+
+## Commit
+
+- `git add -A && git commit -m "phase29aj(p5): planner-first pattern5 infinite early-exit subset"`
+
+## Next (P6 candidate)
+
+- TBD
