## 根本原因
|
## 根本原因
|
||||||
|
|
||||||
- [cond_promoter] がループ内の条件式 `char == " "` を `promoted carrier` に昇格
|
- Trim系のcondition promotion (A-3) が返す `CarrierInfo` は promoted carrier を `carriers` に入れず `loop_var_name` 側に置く設計
|
||||||
- break時のexitブロックでこのcarrierの値をどうするか(join_id)が未定義
|
- Pattern2 が `find_carrier()` で join_id を取ろうとして `[phase229] ... has no join_id` で落ちる
|
||||||
- Phase 229(Promoted Carrier Join ID割り当て)で panic
|
- 該当: `src/mir/loop_pattern_detection/loop_body_carrier_promoter.rs:73` (コメント通り "carriers: Empty")

## 修正対象
|
## 修正内容(P1: 箱理論アプローチ)
|
||||||
|
|
||||||
**Phase 229**: Promoted Carrier Join ID割り当ての拡張
|
**方針**: Pattern2 は Trim(A-3) を自前で join_id 解決しない。Trim は既に `apply_trim_and_normalize()` (= TrimLoopLowerer) が SSOT で ConditionEnv に join_id を登録するので、そちらに責務を寄せて二重実装を消す。
|
||||||
- Loop exit時に promoted carrier が安全に処理される
|
|
||||||
- Exit PHI と promoted carrier の生命周期統合
|
**実装**: `src/mir/builder/control_flow/joinir/patterns/pattern2_with_break.rs`
|
||||||
|
- `promote_and_prepare_carriers()` で Promoted が Trim 由来かチェック (`carrier_info.trim_helper().is_some()`)
|
||||||
|
- Trim の場合:
|
||||||
|
- `promoted_pairs.push()` をスキップ
|
||||||
|
- `DigitPosConditionNormalizer::normalize()` をスキップ
|
||||||
|
- `[phase229]` の promoted_pairs 解決ループ自体を通らない
|
||||||
|
- Trim でない(DigitPos等)なら、現状の promoted_pairs + join_id 解決を維持
|
||||||
|
|
||||||
|
**結果**: "Trim を cond_promoter 側で promote したのに、Pattern2 側で join_id を要求して死ぬ" 構造矛盾が解消
