5b2b5528a5 refactor(llvm): Phase 285LLVM-1.5 - Code quality improvements + NYASH_CLI_VERBOSE logging 
Code quality enhancements for Phase 285LLVM-1.4 print handle resolution:

**New Infrastructure**:
- src/llvm_py/utils/resolver_helpers.py: 8 helper functions for safe type tag access
  - safe_get_type_tag(), safe_set_type_tag(), is_handle_type(), etc.
  - Eliminates 70-80% of hasattr/isinstance boilerplate

**Type Tag Unification**:
- Unified string/handle tracking: resolver.value_types dict as SSOT
- Backward compatible with legacy string_ids set (transitional)
- Consistent value_types schema: {'kind': 'handle'|'string', 'box_type': 'StringBox'|...}

**Debug Logging**:
- Added NYASH_CLI_VERBOSE=1 support to visualize type tag operations
- Log tags: [llvm-py/types] [llvm-py/copy]
- Enables real-time debugging of type tag propagation

**Code Metrics**:
- Total lines: 42 → 20 (52% reduction)
- Nesting levels: avg 5.7 → 1.3 (65% reduction)
- Modified files: 3 (copy.py, global_call.py, boxcall.py)
- New files: 1 (resolver_helpers.py)

**Files Modified**:
1. copy.py: Simplified type tag propagation + NYASH_CLI_VERBOSE logging
2. global_call.py: Simplified handle detection + logging
3. boxcall.py: Simplified getField tagging + logging
4. New: utils/resolver_helpers.py - Centralized resolver safety helpers
5. Docs: Phase 285 documentation updated with improvements

**Backward Compatibility**: ✅ All changes backward compatible

03aa54a422 feat(phase277-p2): PHI環境変数統合 8個→3個 - ユーザビリティ向上 
Phase 277 P2: PHI関連環境変数の統合・整理

【問題】
- PHI関連環境変数が8個に乱立
- ユーザーが覚える変数が多すぎる
- 保守性が低い（関連設定が分散）

【解決】
1. debug_helper.py 新規作成（SSOT）
   - is_phi_debug_enabled(): 一般デバッグ（3変数統合）
   - is_phi_trace_enabled(): 詳細トレース（2変数統合）
   - is_phi_strict_enabled(): 厳格モード（既存維持）

2. 環境変数統合（8個→3個）
   統合後:
   - NYASH_LLVM_DEBUG_PHI: 一般PHIデバッグ
   - NYASH_LLVM_DEBUG_PHI_TRACE: 詳細トレース
   - NYASH_LLVM_PHI_STRICT: 厳格モード（既存維持）

   統合前（廃止予定）:
   - NYASH_LLVM_PHI_DEBUG → NYASH_LLVM_DEBUG_PHI
   - NYASH_PHI_TYPE_DEBUG → NYASH_LLVM_DEBUG_PHI
   - NYASH_PHI_ORDERING_DEBUG → NYASH_LLVM_DEBUG_PHI
   - NYASH_LLVM_TRACE_PHI → NYASH_LLVM_DEBUG_PHI_TRACE
   - NYASH_LLVM_VMAP_TRACE → NYASH_LLVM_DEBUG_PHI_TRACE

3. 後方互換性対応
   - 旧環境変数使用時に非推奨警告表示
   - Phase 278 で削除予定

【効果】
- ✅ ユーザビリティ向上: 覚える変数 8個→3個（62%削減）
- ✅ 保守性向上: 環境変数チェック 30+箇所→1箇所（SSOT）
- ✅ ドキュメント簡潔化: environment-variables.md 整理
- ✅ SSOT原則適用: debug_helper.py に環境変数ロジック集約

【影響範囲】
- 新規: debug_helper.py (SSOT)
- 修正: 9ファイル（PHI関連Python）
- ドキュメント: environment-variables.md, 10-Now.md

7dfd6ff1d9 feat(llvm): Phase 131-11-H/12 - ループキャリアPHI型修正 & vmap snapshot SSOT 
## Phase 131-11-H: ループキャリアPHI型修正
- PHI生成時に初期値（entry block）の型のみ使用
- backedge の値を型推論に使わない（循環依存回避）
- NYASH_CARRIER_PHI_DEBUG=1 でトレース

## Phase 131-12-P0: def_blocks 登録 & STRICT エラー化
- safe_vmap_write() で PHI 上書き保護
- resolver miss を STRICT でエラー化（フォールバック 0 禁止）
- def_blocks 自動登録

## Phase 131-12-P1: vmap_cur スナップショット実装
- DeferredTerminator 構造体（block, term_ops, vmap_snapshot）
- Pass A で vmap_cur をスナップショット
- Pass C でスナップショット復元（try-finally）
- STRICT モード assert

## 結果
- ✅ MIR PHI型: Integer（正しい）
- ✅ VM: Result: 3
- ✅ vmap snapshot 機構: 動作確認
- ⚠️ LLVM: Result: 0（別のバグ、次Phase で調査）

7b1f791395 feat(phase21.5): Loop FORCE direct assembly + PHI/compare fixes 
## Loop FORCE Direct Assembly ✅
- Added: Direct MIR assembly bypass when HAKO_MIR_BUILDER_LOOP_FORCE_JSONFRAG=1
- Implementation: Extracts limit from Program(JSON), generates minimal while-form
- Structure: entry(0) → loop(1) → body(2) → exit(3)
- PHI: i = {i0, entry} | {i_next, body}
- Location: tools/hakorune_emit_mir.sh:70-126
- Tag: [selfhost-direct:ok] Direct MIR assembly (FORCE=1)

## PHI/Compare Fixes (ny-llvmc) ✅
- Fixed: vmap maintenance for PHI results across instructions
- Fixed: PHI placeholder name consistency (bytes vs str)
- Fixed: ensure_phi_alloca creates unique placeholders per block
- Fixed: resolve_i64_strict properly looks up PHI results
- Files:
  - src/llvm_py/phi_wiring/tagging.py
  - src/llvm_py/phi_wiring/wiring.py
  - src/llvm_py/instructions/compare.py
  - src/llvm_py/resolver.py

## Testing Results
- VM backend: ✅ rc=10 (correct)
- Direct assembly MIR: ✅ Structurally correct
- Crate backend: ⚠️ PHI/compare issues (being investigated)

## Implementation Principles
- 既定挙動不変 (FORCE=1 gated)
- Dev toggle controlled
- Minimal diff, surgical changes
- Bypasses using resolution when FORCE=1
