nyash-codex bd39e09c5d docs: Phase 131 P0 structure implementation complete
Document Phase 131 P0 Normalized loop(true) break-once:

**Documentation**:
- docs/development/current/main/phases/phase-131/README.md (234 lines)
  - Goal: loop(true) { <assign>* ; break } in Normalized (PHI-free)
  - Scope: one-time execution loop only
  - Contract: Bool(true) literal + break at end
  - SSOT: EnvLayout, loop structure contract, VM+LLVM parity
  - Current status: structure implemented, execution wiring pending
- docs/development/current/main/10-Now.md
  - Updated Next section with Phase 131 P0 status

**Deliverables** (P0):
-  Complete loop(true) break-once Normalized lowering logic
-  PHI-free implementation (env + continuations)
-  Box-First modular design
-  Foundation for execution (structure verified)
-  Unit tests passing (1155/1155)

**Known Limitation**:
- Execution path not yet wired (dev-only observation mode)
- Follow-up phase needed to route execution through Normalized shadow
- VM/LLVM smokes fail (expected until execution wiring)

**Next Steps**:
1. Modify try_cf_loop_joinir to check Normalized shadow first
2. Add dev-mode routing for loop(true) break-once
3. Implement JoinModule → MIR merge for loop patterns
4. Enable VM/LLVM smoke tests

Phase 命名規則

  • ファイル名: phase-<N>-<title>/ (例: phase-131/)
  • 文書名: <N>-<NN>-<topic>.md (例: 131-11-case-c-summary.md)
    • Phase 番号で自然にソート可能
    • 同一 Phase 内で段階的に追跡可能

作成ルールSSOT

詳しくは ../DOCS_LAYOUT.md を参照。

  • 置き場所: phases/phase-<N>/ 配下のみ
  • 内容: Phase の実装記録・進捗・チェックリスト・検証結果
  • 避けるべき: 複数 Phase で参照される設計・アーキテクチャ(→ design/ へ)
