630ed02c48 feat(joinir): Phase 286 P2.7 - V10不変条件追加（body_bb effects契約） 
- verifier.rs: V10検証追加 - body_bbのblock_effectsは空でなければならない
  - 違反時: "[V10] Loop at depth N has non-empty block_effects for body_bb"
  - テスト: test_v10_body_bb_effects_in_block_effects_fails
- joinir-plan-frag-ssot.md: V10をPlan段階の不変条件に追加
- README.md: P2.7セクション追加

Phase 286 P2.6.1で発見した「lowererはloop_plan.bodyをemitし、
block_effectsのbody_bbは無視する」問題を契約化し再発防止。

843d094598 refactor(joinir): Phase 286 P1-P3 - Boundary contract context enrichment 
- P1: Add alloc_join_param()/alloc_join_local() API to JoinValueSpace
  - Prevents future API misuse (thin wrappers with explicit "JoinIR" context)
  - Updated docs with footnote-style number references

- P2: Enrich error context with host_fn for better diagnostics
  - Added context: &str parameter to verify_boundary_contract_at_creation()
  - Error format now shows: [merge_joinir_mir_blocks host=<fn> ...]

- P3: Add join-side info to error context (continuation count + boundary summary)
  - Uses boundary.continuation_func_ids.len() for join=
  - Adds [conts=X exits=Y conds=Z] suffix with fixed key names
  - Enables faster debugging with log-searchable format

Error format: [merge_joinir_mir_blocks host=X join=Y [conts=A exits=B conds=C]]

2d5607930c docs(edgecfg): Phase 280 - Frag Composition SSOT Positioning (A→B→C) 
## Purpose

Stop pattern number enumeration proliferation by establishing Frag composition API
as the Single Source of Truth (SSOT) for structured control flow → CFG lowering.

Pattern numbers (1-9+) are **symptom labels** for regression tests, NOT architectural
concepts. The architectural SSOT is **Frag composition rules** (seq/if/loop/cleanup).

## Changes Summary

**Phase A (Docs-only, no code)**: SSOT Positioning
- edgecfg-fragments.md: Status Draft → Active SSOT (+243 lines)
  - Added 5 sections: Composition SSOT, Rules, Laws, Fail-Fast, Ownership
  - Documented 3-tier ownership model (Normalizer/Composition/Lowerer)
  - Established composition as pattern absorption destination
- joinir-architecture-overview.md: Pattern absorption documentation (+90 lines)
  - Added Section 0.2: Pattern Number Absorption Destination
  - JoinIR vs Plan comparison (different extraction, same SSOT)
  - Pattern absorption status table (Pattern6/7 as Phase 280 targets)
- phase-280/README.md: Full roadmap (new)

**Phase B (API solidification)**: Contract Verification
- compose.rs: Module-level + function-level Phase 280 docs (+149 lines)
  - Documented composition SSOT, ownership model, usage example
  - Added constraint/composition law sections to seq/if/loop/cleanup
  - Contract verification: All seq/if/loop contracts verified (no gaps)
  - Test gap analysis: No missing tests (wires/exits separation explicitly tested)

**Phase C (Pattern preparation)**: Documentation-only
- normalizer.rs: Pattern6/7 TODO comments (+10 lines)
  - Pattern6: Early exit doesn't fit compose::if_() → cleanup() target
  - Pattern7: 挙動不変保証難 → compose::if_() migration deferred to Phase 281

## Impact

- **Net +460 lines** (docs-heavy, minimal code)
- **4 files modified**, 1 directory created
- **SSOT established**: Frag composition is now THE absorption destination
- **導線固定**: Clear migration path for Pattern6/7 (Phase 281+)
- **No behavior change**: Documentation-only for Phase C (tests not run)

## Phase 280 Goal Achieved

✅ SSOT positioning + 導線固定 (NOT full migration - that's Phase 281)
✅ Phase A complete: Docs updated to "Active SSOT"
✅ Phase B complete: API contract verified and documented
✅ Phase C complete: Pattern6/7 hand-rolled locations documented

## Next Phase (Phase 281+)

- Phase 281: Full Pattern6/7 absorption (replace hand-rolled with compose_*)
- Phase 282: Router shrinkage (pattern numbers → test labels)
- Phase 283+: Pattern8 and beyond

757193891f feat(llvm/phi): Phase 277 P1 - fail-fast validation for PHI strict mode 
## Summary
Implemented fail-fast validation for PHI ordering and value resolution in strict mode.

## Changes

### P1-1: Strict mode for "PHI after terminator"
- File: `src/llvm_py/phi_wiring/wiring.py::ensure_phi`
- Behavior: `NYASH_LLVM_PHI_STRICT=1` → RuntimeError if PHI created after terminator
- Default: Warning only (no regression)

### P1-2: Strict mode for "fallback 0"
- File: `src/llvm_py/phi_wiring/wiring.py::wire_incomings`
- Behavior: Strict mode forbids silent fallback to 0 (2 locations)
  - Location 1: Unresolvable incoming value
  - Location 2: Type coercion failure
- Error messages point to next debug file: `llvm_builder.py::_value_at_end_i64`

### P1-3: Connect verify_phi_ordering() to execution path
- File: `src/llvm_py/builders/function_lower.py`
- Behavior: Verify PHI ordering after all instructions emitted
- Debug mode: Shows "✅ All N blocks have correct PHI ordering"
- Strict mode: Raises RuntimeError with block list if violations found

## Testing
✅ Test 1: strict=OFF - passes without errors
✅ Test 2: strict=ON - passes without errors (no violations in test fixtures)
✅ Test 3: debug mode - verify_phi_ordering() connected and running

## Scope
- LLVM harness (Python) changes only
- No new environment variables (uses existing 3 from Phase 277 P2)
- No JoinIR/Rust changes (root fix is Phase 279)
- Default behavior unchanged (strict mode opt-in)

## Next Steps
- Phase 278: Remove deprecated env var support
- Phase 279: Root fix - unify "2本のコンパイラ" pipelines

21387f3816 feat(edgecfg): Phase 265 P2 - seq/if_ 実装（wires/exits 分離） 
## 目的

「解決済み配線（wires）」と「未解決 exit（exits）」を分離し、
Frag 合成の基本パターンを完成させる。

## 実装内容

### 1. Frag 構造体の変更
- `wires: Vec<EdgeStub>` フィールド追加
- 不変条件:
  - exits: target = None のみ（未配線、外へ出る exit）
  - wires: target = Some(...) のみ（配線済み、内部配線）

### 2. loop_() の wires 対応
- Break/Continue を exits から wires に移動
- P1 テスト 3個を wires 検証に更新

### 3. seq(a, b) 実装
- a.Normal → b.entry を wires に追加（内部配線）
- seq の exits[Normal] は b の Normal のみ
- 新規テスト 2個追加

### 4. if_(header, cond, t, e, join_frag) 実装
- シグネチャ変更: join: BasicBlockId → join_frag: Frag
- t/e.Normal → join_frag.entry を wires に追加
- if の exits は join_frag.exits
- 新規テスト 2個追加

### 5. verify_frag_invariants() 強化
- wires/exits 分離契約の検証追加（警告のみ）
- Err 化は Phase 266 で実施

## テスト結果

- edgecfg::api: 13/13 PASS（frag 3 + compose 9 + verify 1）
- 全 lib テスト: 1388/1388 PASS（退行なし）

## 核心的な設計判断

1. **wires/exits 分離**:
   - 問題: 解決済み配線と未解決 exit を混ぜると再配線バグ
   - 解決: 分離して不変条件を強化
   - 効果: Phase 266 で wires を MIR terminator に落とすだけ

2. **if_ は join_frag 受け取り**:
   - 問題: join: BasicBlockId では「join block」か「join 以降」か曖昧
   - 解決: join_frag: Frag で「join 以降」を明確化
   - 効果: PHI 生成の柔軟性確保

3. **verify は警告のみ**:
   - P2 の役割: wires/exits 分離の証明に集中
   - Phase 266 で MIR 生成時に厳格化

## 次フェーズへの橋渡し

- Phase 266: wires を MIR terminator に落とす
- Phase 267: Pattern6/7/8 を Frag 化

cda034fe8f feat(edgecfg): Phase 265 P1 - compose 配線ロジック実装（test-only PoC） 
## 目的
Frag/ExitKind が BasicBlockId 層で配線できることを証明

## 実装完了内容
- EdgeStub に target: Option<BasicBlockId> 追加
- compose::loop_() 配線ロジック実装（Continue → header, Break → after）
- verify_frag_invariants() 配線契約検証追加
- test-only PoC で実証完了（5個のテスト）

## 配線契約
- Continue(loop_id) の EdgeStub.target = Some(header)
- Break(loop_id) の EdgeStub.target = Some(after)
- Normal/Return/Unwind の EdgeStub.target = None（上位へ伝搬）

## テスト
- compose::tests: 5 PASS（既存2個更新 + 新規3個追加）
- verify::tests: 1 PASS（基本smoke test）
- cargo test -p nyash-rust --lib: SUCCESS

## 重要な制約
- MIR 命令生成はまだしない（Frag 層の配線能力証明のみ）
- NormalizedShadow/JoinIR層への適用は Phase 266 に繰り越し
- Pattern6/7/8 未改変（配線能力の証明に集中）

## 次のステップ
- Phase 265 P2: seq/if_ 実装（順次合成・条件分岐合成）
- Phase 266: JoinIR-VM Bridge 改修後、NormalizedShadow への適用
