525e59bc8d feat(loop-phi): Add body-local variable PHI generation for Rust AST loops 
Phase 25.1c/k: Fix ValueId undefined errors in loops with body-local variables

**Problem:**
- FuncScannerBox.scan_all_boxes/1 and BreakFinderBox._find_loops/2 had ValueId
  undefined errors for variables declared inside loop bodies
- LoopFormBuilder only generated PHIs for preheader variables, missing body-locals
- Example: `local ch = s.substring(i, i+1)` inside loop → undefined on next iteration

**Solution:**
1. **Rust AST path** (src/mir/loop_builder.rs):
   - Detect body-local variables by comparing body_end_vars vs current_vars
   - Generate empty PHI nodes at loop header for body-local variables
   - Seal PHIs with latch + continue snapshot inputs after seal_phis()
   - Added HAKO_LOOP_PHI_TRACE=1 logging for debugging

2. **JSON v0 path** (already fixed in previous session):
   - src/runner/json_v0_bridge/lowering/loop_.rs handles body-locals
   - Uses same strategy but for JSON v0 bridge lowering

**Results:**
- ✅ FuncScannerBox.scan_all_boxes: 41 body-local PHIs generated
- ✅ Main.main (demo harness): 23 body-local PHIs generated
- ⚠️ Still some ValueId undefined errors remaining (exit PHI issue)

**Files changed:**
- src/mir/loop_builder.rs: body-local PHI generation logic
- lang/src/compiler/entry/func_scanner.hako: debug logging
- /tmp/stageb_funcscan_demo.hako: test harness

8b44c5009f fix(mir): fix else block scope bug - PHI materialization order 
Root Cause:
- Else blocks were not propagating variable assignments to outer scope
- Bug 1 (if_form.rs): PHI materialization happened before variable_map reset,
  causing PHI nodes to be lost
- Bug 2 (phi.rs): Variable merge didn't check if else branch modified variables

Changes:
- src/mir/builder/if_form.rs:93-127
  - Reordered: reset variable_map BEFORE materializing PHI nodes
  - Now matches then-branch pattern (reset → materialize → execute)
  - Applied to both "else" and "no else" branches for consistency
- src/mir/builder/phi.rs:137-154
  - Added else_modified_var check to detect variable modifications
  - Use modified value from else_var_map_end_opt when available
  - Fall back to pre-if value only when truly not modified

Test Results:
✅ Simple block: { x=42 } → 42
✅ If block: if 1 { x=42 } → 42
✅ Else block: if 0 { x=99 } else { x=42 } → 42 (FIXED!)
✅ Stage-B body extraction: "return 42" correctly extracted (was null)

Impact:
- Else block variable assignments now work correctly
- Stage-B compiler body extraction restored
- Selfhost builder path can now function
- Foundation for Phase 21.x progress

47f4ca0e44 📚 docs: Record field declaration design discussion in papers 
## Summary
Documented the "init block vs fields-at-top" design discussion as a valuable example of AI-human collaboration in language design.

## Changes

### Paper G (AI Collaboration)
- Added field-declaration-design.md documenting the entire discussion flow
- Showcased how complex init block proposal evolved to simple "fields at top" rule
- Demonstrates AI's tendency toward complexity vs human intuition for simplicity

### Paper H (AI Practical Patterns)
- Added Pattern #17: "Gradual Refinement Pattern" (段階的洗練型)
- Documents the process: Complex AI proposal → Detailed analysis → Human insight → Convergence
- Field declaration design as a typical example

### Paper K (Explosive Incidents)
- Added Incident #046: "init block vs fields-at-top incident"
- Updated total count to 46 incidents
- Shows how a single human comment redirected entire design approach

## Design Decision
After analysis, decided that BoxIndex should remain a compiler-internal structure, not a core Box:
- Core Boxes: User-instantiable runtime values (String, Integer, Array, Map)
- Compiler internals: BoxIndex for name resolution (compile-time only)
- Clear separation of concerns between language features and compiler tools

## Philosophy
This discussion exemplifies key principles:
- The best design needs no explanation
- Constraints provide clarity, not limitation
- "Everything is Box" doesn't mean "compiler internals are Boxes"
- AI tends toward theoretical completeness; humans toward practical simplicity

d90216e9c4 📚 Phase 15 - セルフホスティング戦略の明確化とEXE-first実装 
## 主な変更点

### 🎯 戦略の転換と明確化
- PyVMを開発ツールとして位置づけ（本番経路ではない）
- EXE-first戦略を明確に優先（build_compiler_exe.sh実装済み）
- Phase順序の整理: 15.2(LLVM)→15.3(コンパイラ)→15.4(VM)

### 🚀 セルフホスティング基盤の実装
- apps/selfhost-compiler/にNyashコンパイラMVP実装
  - compiler.nyash: メインエントリー（位置引数対応）
  - boxes/: parser_box, emitter_box, debug_box分離
- tools/build_compiler_exe.sh: ネイティブEXEビルド＋dist配布
- Python MVPパーサーStage-2完成（local/if/loop/call/method/new）

### 📝 ドキュメント整備
- Phase 15 README/ROADMAP更新（Self-Hosting優先明記）
- docs/guides/exe-first-wsl.md: WSLクイックスタート追加
- docs/private/papers/: 論文G～L、爆速事件簿41事例収録

### 🔧 技術的改善
- JSON v0 Bridge: If/Loop PHI生成実装（ChatGPT協力）
- PyVM/llvmliteパリティ検証スイート追加
- using/namespace機能（gated実装、Phase 15では非解決）

## 次のステップ
1. パーサー無限ループ修正（未実装関数の実装）
2. EXEビルドとセルフホスティング実証
3. c0→c1→c1'ブートストラップループ確立

af11c6855b 🚀 Start Phase 15.3: Nyash compiler MVP implementation 
Major milestone:
- Set up apps/selfhost-compiler/ directory structure
- Implement basic Nyash compiler in Nyash (CompilerBox)
- Stage-1: Basic arithmetic parser (int/string/+/-/*/括弧/return)
- JSON v0 output compatible with --ny-parser-pipe
- Runner integration with NYASH_USE_NY_COMPILER=1 flag
- Comprehensive smoke tests for PHI/Bridge/Stage-2

Technical updates:
- Updated CLAUDE.md with Phase 15.3 status and MIR14 details
- Statement separation policy: newline-based with minimal ASI
- Fixed runaway ny-parser-pipe processes (CPU 94.9%)
- Clarified MIR14 as canonical instruction set (not 13/18)
- LoopForm strategy: PHI auto-generation during reverse lowering

Collaborative development:
- ChatGPT5 implementing compiler skeleton
- Codex provided LoopForm PHI generation guidance
- Claude maintaining documentation and coordination

🎉 セルフホスティングの歴史的一歩！自分自身をコンパイルする日が近いにゃ！

3ba96d9a03 🚀 feat: Multiple improvements for Nyash parser and LLVM backend 
Parser improvements:
- Added expression statement fallback in parse_statement() for flexible syntax
- Fixed ternary operator to use PeekExpr instead of If AST (better lowering)
- Added peek_token() check to avoid ?/?: operator conflicts

LLVM Python improvements:
- Added optional ESC_JSON_FIX environment flag for string concatenation
- Improved PHI generation with better default handling
- Enhanced substring tracking for esc_json pattern

Documentation updates:
- Updated language guide with peek expression examples
- Added box theory diagrams to Phase 15 planning
- Clarified peek vs when syntax differences

These changes enable cleaner parser implementation for self-hosting,
especially for handling digit conversion with peek expressions instead
of 19-line if-else chains.

53a869136f 📚 ABI統合ドキュメント整理 & LLVM BuilderCursor改善 
## ABI関連
- docs/reference/abi/ABI_INDEX.md 作成（統合インデックス）
- 分散していたABI/TypeBoxドキュメントへのリンク集約
- CLAUDE.mdに「ABI統合インデックス」リンク追加
- ABI移行タイミング詳細検討（LLVM完成後のPhase 15.5推奨）

## LLVM改善（ChatGPT5協力）
- BuilderCursor導入でposition管理を構造化
- emit_return/jump/branchをcursor経由に統一
- PHI/terminator問題への対策改善
- より明確なbasic block位置管理
