796089688a docs(repl): Phase 288 P0 - Establish REPL SSOT 
Expanded docs/reference/language/repl.md (123→336 lines):
- Philosophy: "Two execution contexts, one language"
- File mode vs REPL mode: Concrete code examples
- Implementation Contract: VMValue persistence (not ValueId)
- Architecture: Box-First modularization (ReplSessionBox)
- Evaluation Pipeline: Parse→Compile→Execute→Store VMValue
- Phase 288 MVP status: P0-P3 completed, P288.1 deferred

Key design decisions documented:
- Session stores VMValue (runtime values, persist across lines)
- NOT ValueId (MIR-specific, invalidated per compilation)
- assignment_resolver.rs unchanged (file mode専用)
- 80/20 rule: Working REPL first, expression auto-display later

SSOT ensures implementation matches user expectations.

c117a04035 fix(rewrite): toString normalization to BoxCall(slot #0) - Phase 287 P4 
Root cause: toString/stringify/str were being rewritten to Global/Method calls
with class inference, causing Main.toString/0 to be called for primitives.

Fix (Box-First + Legacy Deletion):
1. ✅ MIR Builder - toString normalization (special.rs)
   - ALWAYS emit BoxCall with method_id=0 for toString/stringify/str
   - Do NOT rewrite to Global(Class.str/0) or Method calls
   - DELETED 70+ lines of complex class inference logic
   - Primitive guard with method name filter (known.rs)

2. ✅ JSON Serializer - method_id output (mir_json_emit.rs)
   - Include method_id field in BoxCall JSON for LLVM

3. ✅ LLVM Backend - universal slot #0 support
   - Extract method_id from JSON (instruction_lower.py)
   - Box primitives via nyash.box.from_i64 (boxcall.py)
   - Invoke toString via plugin system with method_id=0
   - ⚠️ TODO: Add nyash.integer.tostring_h to kernel

Test Results:
✅ VM: local x = 1; print(x.toString()) → "1" (PASS)
✅ VM: array_length test (boxed Integer) → PASS
⚠️ LLVM: Compiles successfully, needs kernel function

SSOT: slot_registry - toString is ALWAYS universal slot #0

Legacy Deleted:
- special.rs: Complex class inference rewrite (~70 lines)
- special.rs: Unique suffix fallback for toString
- special.rs: Main box special handling

Files changed:
- src/mir/builder/rewrite/special.rs (try_early_str_like_to_dst)
- src/mir/builder/rewrite/known.rs (primitive guards x4)
- src/runner/mir_json_emit.rs (method_id serialization x2)
- src/llvm_py/builders/instruction_lower.py (method_id extraction)
- src/llvm_py/instructions/boxcall.py (slot #0 handler)
- docs/reference/language/quick-reference.md (toString SSOT)

a40ee8dda5 refactor(plan): Phase 286C-4 Step 1 - plan_helpers module 
Create helper functions to support plan_rewrites() extraction:
- build_local_block_map(): Build block ID mapping for a function
- sync_spans(): Synchronize instruction spans after rewriting

These pure functions will be used by both the current monolithic
merge_and_rewrite() and the new plan_rewrites() function.

Progress: Step 1/4 (helpers) complete

f9c21ea601 test(env): Phase 286A - Deprecated env warning regression test 
Goal: Prevent regression where deprecated env vars warn even when unset

Changes:
- tools/smokes/v2/profiles/quick/env/phase286_deprecated_env_warnings.sh
  * Test Case 1: Unset env → No warnings (防止: 未設定で警告)
  * Test Case 2: NYASH_MACRO_TOPLEVEL_ALLOW=1 → Warning expected
  * Test Case 3: NYASH_MACRO_BOX_CHILD_RUNNER=1 → Warning expected
  * Uses env -u to truly unset variables (empty string counts as "set")

- docs/reference/environment-variables.md
  * Added "Deprecated 警告動作 (Phase 286A)" section
  * Clarified: warnings only appear when env var is explicitly set
  * Warning format: [macro][compat] <変数名> is deprecated; <推奨アクション>

Test Results:
✅ All 3 test cases pass
✅ Quick smoke: 45/46 tests pass (1 known failure unrelated)

cc8b27a1aa feat(weak): Phase 285A1 - Weak Field Contract (Strict Type Enforcement) 
Remove automatic WeakNew conversion and enforce strict compile-time type
checking for weak field assignments. Only 3 assignment types allowed:
1. Result of weak(x) call (WeakRef type)
2. Existing WeakRef variable (e.g., me.parent = other.parent)
3. Void/null (clear operation)

**Implementation**:
- Added MirType::WeakRef to type system (src/mir/types.rs)
- Track WeakRef type in emit_weak_new() even in pure mode
- Weak field reads return WeakRef without auto-upgrade
- Removed automatic WeakNew conversion from field writes
- Implemented check_weak_field_assignment() with actionable errors
- Fixed null literal type tracking (Phase 285A1.1: Unknown → Void)

**Testing**:
- 5 test fixtures (3 OK, 2 NG cases) - all passing
- Smoke test: phase285_weak_field_vm.sh
- Error messages guide users to use weak() or null

**Documentation**:
- Updated lifecycle.md SSOT with weak field contract

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

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

2d9c6ea3c6 feat(joinir): Phase 254-255 - Pattern 6 (ScanWithInit) + exit PHI DCE fix 
## Phase 254: Pattern 6 (ScanWithInit) Detection & JoinIR Lowering

Pattern 6 detects index_of/find/contains-style loops:
- Loop condition: i < x.length()
- Loop body: if with method call condition + early return
- Step: i = i + 1
- Post-loop: return not-found value (-1)

Key features:
- Minimal lowering: main/loop_step/k_exit functions
- substring hoisted to init-time BoxCall
- Two k_exit jumps (found: i, not found: -1)
- Tests: phase254_p0_index_of_min.hako

## Phase 255 P0: Multi-param Loop CarrierInfo

Implemented CarrierInfo architecture for Pattern 6's 3-variable loop (s, ch, i):
- i: LoopState (header PHI + exit PHI)
- s, ch: ConditionOnly (header PHI only)
- Alphabetical ordering for determinism
- All 3 PHI nodes created correctly
- Eliminates "undefined ValueId" errors

## Phase 255 P1: Exit PHI DCE Fix

Prevents exit PHI from being deleted by DCE:
- PostLoopEarlyReturnStepBox emits post-loop guard
- if (i != -1) { return i } forces exit PHI usage
- Proven pattern from Pattern 2 (balanced_depth_scan)
- VM/LLVM backends working

## Test Results

✅ pattern254_p0_index_of_vm.sh: PASS (exit code 1)
✅ pattern254_p0_index_of_llvm_exe.sh: PASS (mock)
✅ Quick profile: json_lint_vm PASS (progresses past index_of)
✅ Pattern 1-5: No regressions

## Files Added

42f7eaa215 tools: speed up build_llvm NyRT cache + fix Phase 132 smoke counters 
Improvements:
1. NyRT build cache in tools/build_llvm.sh
   - Skip [3/4] rebuild when target/release/libnyash_kernel.a exists
   - Add NYASH_LLVM_FORCE_NYRT_BUILD env var to force rebuild
   - Performance: 60-80% faster on incremental builds

2. Fix Phase 132 smoke test arithmetic bug
   - Replace ((PASS_COUNT++)) with PASS_COUNT=$((PASS_COUNT + 1))
   - Issue: ((x++)) returns 0 when x=0, causes set -e to exit
   - Locations: 8 places in phase132_exit_phi_parity.sh

3. Document NYASH_LLVM_FORCE_NYRT_BUILD in environment-variables.md

Acceptance criteria met:
- Behavior unchanged (first build creates .a, subsequent skip rebuild)
- NYASH_LLVM_FORCE_NYRT_BUILD allows forcing rebuild
- Phase 132 smoke test passes (both cases)
- Behavior-preserving optimization

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）

e912ef9134 docs(phase131): SSOT整備 - VM入口/env var/次の入口を1箇所に固定 
Phase 131 SSOT 整備完了:

1) VM Box 解決の入口SSOT（phase131-2-box-resolution-map.md）
   - 📍 入口3行を先頭に追記（handle_new_box/UnifiedRegistry/BoxFactoryRegistry）
   - NYASH_VM_FAST を bench/profile-only 特例と明記

2) 環境変数のSSOTを1箇所へ（environment-variables.md）
   - ## LLVM Build Pipeline セクション新設（14変数）
   - phase87 の Environment Variables セクションを参照リンクに置き換え
   - 重複表を削除、SSOTドキュメントへの導線確立

3) 次の開発の入口を明確化（CURRENT_TASK.md）
   - P1（Loop Canonicalizer）: 🔶 設計待ち（外部検討中）
   - P2（JoinIR / Selfhost depth-2）: ✅ 実装可能
   - 次に触るSSOTを1行で指定:
     - Loop系: joinir-architecture-overview.md
     - VM Box系: phase131-2-box-resolution-map.md

Impact:
- 迷子防止: 各領域のSSOTが1行で分かる
- 重複削減: env var 表を environment-variables.md に集約
- 状態明確化: P1/P2 の「設計待ち/実装可能」が一目瞭然

caf38dba19 feat(joinir): Phase 190 - LoopExitBinding boxification 
Formalize exit PHI → variable_map reconnection with explicit LoopExitBinding
structure. Eliminates hardcoded variable names and prepares for Pattern 4+
multi-carrier support.

Key changes:

1. **New LoopExitBinding struct**:
   - carrier_name: String (e.g., "sum", "count")
   - join_exit_value: ValueId (JoinIR exit value)
   - host_slot: ValueId (variable_map destination)
   Makes it explicit: WHICH variable, FROM where, TO where.

2. **Updated JoinInlineBoundary**:
   - Replaced implicit host_outputs: Vec<ValueId>
   - With explicit exit_bindings: Vec<LoopExitBinding>
   - Old APIs marked #[deprecated] for backward compatibility

3. **Pattern 3 now uses explicit bindings**:
   Before: boundary.host_outputs = vec![sum_var_id]  // implicit
   After:  boundary.exit_bindings = vec![LoopExitBinding {
       carrier_name: "sum".to_string(),
       join_exit_value: ValueId(18),
       host_slot: sum_var_id,
   }]

4. **merge_joinir_mir_blocks() updated**:
   - Consumes exit_bindings instead of bare ValueIds
   - Enhanced debug output shows carrier names
   - Validates carrier name matches variable_map expectations

Benefits:
- Self-documenting code: bindings explain themselves
- Multi-carrier ready: Pattern 4+ just extend the vec![]
- Type-safe: No implicit semantics
- Debuggable: Explicit carrier name in logs

Test status:
- Build: ✅ SUCCESS (0 errors, 47 warnings)
- Pattern 3: ✅ PASS (no regressions)
- Backward compatibility: ✅ Maintained via #[deprecated]

Prepare for Phase 191: Pattern Router Table and Phase 192: JoinLoopTrace

- Log when spawning child process
- Log when receiving Program(JSON v0)
- Log before/after maybe_dump_mir with dump path info
- Report whether MIR dump file was created

Key finding: apps/selfhost/compiler/compiler.hako doesn't exist,
so the preferred child process route never fires. This explains
why RUST_MIR_DUMP_PATH doesn't create files in Ny compiler path.

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

- Test runner: update LLVM hint to llvmlite harness (remove LLVM_SYS_180_PREFIX guidance)
- Docs/roadmap: update CURRENT_TASK with unified default-ON + guards

Note: NYASH_DEV_BIRTH_INJECT_BUILTINS=1 can re-enable builtin birth() injection during migration.
