5a88c4eb23 refactor(llvm-py): Phase 3 boxification - Strategic extraction 
Extract complex logic while keeping simple parts inline:

1. StringBoxerBox (15 lines)
   - Box string pointers (i8*) to handles (i64)
   - Eliminate function declaration boilerplate
   - Clear single responsibility

2. ReturnPhiSynthesizerBox (101 lines)
   - Synthesize PHI nodes for return values
   - should_synthesize_phi(): Zero-like detection
   - synthesize_phi(): PHI creation with predecessors
   - Respects _disable_phi_synthesis flag

What was NOT boxified (good decisions):
- Fast path vmap lookup (13 lines): Too simple
- Global vmap fallback (7 lines): Too small
- Default value generation (18 lines): Clear as-is

Impact:
- lower_return(): 166→117 lines (-29% reduction)
- File size: 250→352 lines (+102 for organization)
- Testable units: 2→4 (+2 new Boxes)

Tests:
- phase286_pattern5_return_min.hako: PASS (exit 7)
- phase284_p1_return_in_loop_llvm.sh: PASS
- phase284_p2_return_in_loop_llvm.sh: PASS

32aa0ddf69 refactor(llvm-py): Box-First refactoring of ret.py (Phase 1-2) 
Extract two responsibility Boxes following Box-First principle:

1. UnreachableReturnHandlerBox (Phase 1)
   - Handle unreachable block returns with Fail-Fast principle
   - Implements Phase 284-P2 unreachable semantics
   - Moved os/sys imports to file header

2. ReturnTypeAdjusterBox (Phase 2)
   - Handle ptr↔int conversion and int width adjustment
   - Isolate type coercion logic for LLVM compatibility
   - Support truncate/extend for integer width mismatches

Changes:
- File size: 205→249 lines (+21% for better organization)
- Reduced lower_return() complexity
- Preserved all Phase 284-P2 comments and semantics
- No breaking changes

Tests:
- phase286_pattern5_return_min.hako: PASS (exit 7)
- phase284_p2_return_in_loop_llvm.sh: PASS
- Quick profile: 154/154 PASS

225600b5f9 fix(llvm): Phase 284 P2 - Use unreachable for null returns (Fail-Fast) 
MIR generates unreachable blocks with null return values (e.g., after loop(true)).
LLVM type-checks ALL blocks, so we must match function signatures.

Solution: Use builder.unreachable() instead of ret void for non-void functions.
- Type-safe: Satisfies LLVM type checker without return value
- Fail-Fast: Immediate crash if "unreachable" block is executed
- No silent failures

Test results:
✅ phase284_p2_return_in_loop_llvm: PASS (integration)
✅ phase285_p2_weak_upgrade_success_llvm: PASS (already passing)
✅ quick 154/154: PASS (no regression)

ce2baa0d47 feat(llvm): Phase 285 P3 - KeepAlive/ReleaseStrong LLVM implementation 
Phase 285 P3: LLVM One-Pass (VM/LLVM一気通貫の最小ゲート)

## 実装内容

### 1. LLVM Backend (Python)
- src/llvm_py/instructions/lifecycle.py: NEW
  - lower_keepalive(): no-op (DCE/liveness only)
  - lower_release_strong(): ny_release_strong() 呼び出し
- src/llvm_py/builders/instruction_lower.py:
  - KeepAlive/ReleaseStrong ディスパッチエントリ追加

### 2. Runtime (Rust)
- crates/nyash_kernel/src/lib.rs:
  - ny_release_strong(handle: i64): handles::drop() 呼び出し
  - Phase 287対応（変数上書きセマンティクス）

### 3. MIR JSON Serialization
- src/runner/mir_json_emit.rs:
  - KeepAlive/ReleaseStrong JSON emit 追加（両関数）
  - {"op":"keepalive","values":[...]}
  - {"op":"release_strong","values":[...]}

## テスト結果

✅ **phase285_p2_weak_upgrade_fail_llvm**: PASS (exit 1, weak_to_strong null)
⏸️ **phase285_p2_weak_upgrade_success_llvm**: SKIP (--version に features 表示なし)
⏸️ **phase284_p2_return_in_loop_llvm**: SKIP (同上)

## SKIP理由（--version feature表示問題）

テストスクリプトが `--version | grep "features.*llvm"` で環境チェックするが、
現在の --version は "nyash 1.0" のみ出力。LLVM feature有効でも SKIP される。

**対応方針**: Phase 285 P3 目的（KeepAlive/ReleaseStrong LLVM実装）達成。
--version feature表示は Phase 286以降で対応予定。

## 検証

- cargo build --release --features llvm: OK
- weak_upgrade_fail_llvm: PASS (VM/LLVM parity確認)
- quick gate: 154/154 PASS (退行なし)

4a5e2bd330 refactor(rewrite): Phase 287 P5 - Code cleanup after toString SSOT 
Three targeted cleanups following Phase 287 P4 toString normalization:

1. known.rs: Extract primitive guard into helper function
   - Unified 4 duplicate guard blocks (60 lines) into single function (15 lines)
   - 75% code reduction with improved testability
   - Function: should_block_primitive_str_rewrite()

2. special.rs: Extract trace helper
   - Unified 3 duplicate NYASH_STATIC_CALL_TRACE checks
   - Function: trace_tostring()

3. boxcall.py: Constant-ify magic numbers
   - UNIVERSAL_SLOT_TOSTRING = 0 (self-documenting)
   - TOSTRING_METHODS = ("toString", "stringify", "str")

Total impact: ~45 lines reduced, improved maintainability.

SSOT maintained: toString always uses universal slot #0.

b696f6c4c4 fix(llvm): Use nyash.any.toString_h for universal slot #0 - Phase 287 P4 
SSOT unification: All toString calls now use nyash.any.toString_h(handle)
instead of plugin invoke system. This works for ALL types:
- IntegerBox, FloatBox, BoolBox, StringBox
- ArrayBox, MapBox, user-defined boxes

Changes:
- LLVM boxcall.py: Replace plugin invoke with direct nyash.any.toString_h call
- Deleted complex 6-argument plugin invoke for method_id=0
- Primitive i64 → box via nyash.box.from_i64 → toString via universal SSOT

Test Results (VM/LLVM parity achieved):
✅ VM: local x = 1; print(x.toString()) → "1"
✅ LLVM: local x = 1; print(x.toString()) → "1"
✅ VM: array_length (boxed Integer) → "0\n1\n2\n3"
✅ LLVM: array_length (boxed Integer) → "0\n1\n2\n3"

SSOT: nyash.any.toString_h = universal slot #0 handler (kernel)

Files changed:
- src/llvm_py/instructions/boxcall.py (universal slot #0 handler)

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)

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

83c897eb5d feat(llvm): Phase 285LLVM-1.4 - print Handle Resolution (type tag propagation) 
Fix LLVM print to output 42 instead of 4 (handle value) for field access.

Root cause: Type tags lost through MIR copy instruction chains
- getField tagged ValueId 16 as handle
- MIR copy chain: 16 → 17 → 18
- print used ValueId 18 (not tagged) → treated as raw integer

Solution: Type-tag based handle detection with copy propagation
- boxcall.py: Tag getField results as handles
- global_call.py: Skip boxing for handles in print
- copy.py: Propagate value_types tags through copy chains

Test coverage:
- apps/tests/phase285_print_raw_int.hako: Raw int regression check
- apps/tests/phase285_userbox_field_basic.hako: Field access parity

Result: VM/LLVM parity achieved (both output 42) ✅

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

9a76a199ee feat(phase276-p0): Quick Win improvements - type helper SSOT + debug cleanup 
Phase 276 P0 post-Phase 275 robustness improvements:

1. Debug cleanup (wiring.py L100-103):
   - Remove traceback.format_stack() output
   - Cleaner debug logs after Phase 275 completion

2. box_from_f64 usage investigation:
   - Confirmed ZERO usage (Rust/Python/MIR)
   - Ready for deletion (Phase 275 unboxed double SSOT)
   - crates/nyash_kernel/src/lib.rs L244-252, L971-982

3. Type resolution SSOT (⭐ most important):
   - New file: src/llvm_py/phi_wiring/type_helper.py (72 lines)
   - Unified 3 duplicate logic sites:
     * tagging.py: inst.get("dst_type") → type_helper.get_phi_dst_type()
     * llvm_builder.py: 9 lines → 2 lines (-7)
     * wiring.py: 18 lines → 5 lines (-13)
   - Priority: MIR JSON dst_type > resolver.value_types
   - Benefits: SSOT principle, bug prevention, easy extension

4. Type mismatch warning enhancement (wiring.py L63-79):
   - CRITICAL warning for predeclared PHI type mismatch
   - PhiManager.invalidate_phi() notification
   - Early bug detection with ⚠️  marker

Effects:
- Type resolution logic: 3 sites → 1 SSOT (type_helper.py)
- Code reduction: -20 lines duplicate logic
- Robustness: SSOT principle, CRITICAL warnings, Fail-Fast
- Debuggability: cleaner logs, prominent type mismatch alerts

Testing:
- LLVM harness: exit=3 verified (/tmp/test_p275_debug2.hako)
- NYASH_PHI_TYPE_DEBUG=1: correct type resolution confirmed

Docs:
- Phase 276 P0 completion: docs/.../phase-276/P0-COMPLETION.md
- 10-Now.md: Phase 276 P0 ✅, Phase 275 P0 completed section

Next steps (Phase 277 P0 recommended):
- Delete box_from_f64 (nyash.box.from_f64, nyash.float.box_from_f64)
- Adopt dst_type_to_llvm_type() helper

1. MIR型伝播順序修正 (lifecycle.rs)
   - BinOp repropagation → PHI resolution に変更
   - Int+Float → Float promotion を PHI推論前に実行

2. MIR JSON Float型出力 (mir_json_emit.rs)
   - PHI dst_type に Float case 追加（2箇所）

3. LLVM PHI型対応 (wiring.py, tagging.py, llvm_builder.py)
   - ensure_phi に dst_type パラメータ追加
   - f64 の場合 ir.DoubleType() PHI 生成
   - 型互換性チェック付き predeclared PHI 再利用

4. LLVM Float演算対応
   - compare.py: ensure_double helper (Float unboxing for fcmp)
   - binop.py: Int+Float → sitofp→fadd (unboxed double)

【検証】
- LLVM IR: phi double [%"float_int_add", %"bb0"] ✅
- VM/LLVM parity: exit=3 ✅
- PHI duplicate 解消: 型チェックで再利用 ✅

【影響範囲】
- Rust MIR builder: 3ファイル (型伝播ロジック)
- LLVM harness: 5ファイル (PHI型対応)
- Kernel: 1ファイル (box_from_f64 helper - 予備)

41d28330e9 feat(select): Task 2-E complete - VM/LLVM backend support for Select instruction 
Phase 256 P1.5: Implement Select instruction (ternary conditional) across entire MIR pipeline

Task 2-E Implementation:
- Added Select ValueId entry to effects() in instruction/methods.rs (pure operation)
- Added Select case to dst_value() for definition tracking
- Added Select case to used_values() for use-def chains (cond, then_val, else_val)
- Fixed non-exhaustive pattern matches in 5 locations:
  * src/mir/instruction/methods.rs: 3 match arms (effects, dst_value, used_values)
  * src/mir/printer_helpers.rs: format_instruction display
  * src/mir/query.rs: reads_of and writes_of MirQuery trait

- Created VM backend: src/llvm_py/instructions/select.py
  * lower_select() implements ternary: dst = cond ? then_val : else_val
  * Converts cond to i1 for boolean test
  * Uses llvmlite builder.select() for LLVM IR generation

- Integrated Select dispatch in instruction_lower.py
  * Imported lower_select module
  * Added select case to instruction dispatch (after barrier, before while)
  * Passes resolver, ValueIds, and CFG context

Compilation Status: ✅ 0 errors (cargo build --release succeeded)
MIR Output: ✅ Select instructions present in generated MIR
Next: Investigate SSA undefined value issue in Pattern7 loop_step

aad01a1079 feat(llvm): Phase 132-P2 - Dict ctx removal (FunctionLowerContext SSOT completion) 
Completed SSOT unification for FunctionLowerContext by removing the manual
dict ctx creation and assignment in function_lower.py.

Changes:
- Removed builder.ctx = dict(...) creation (18 lines, lines 313-330)
- Removed builder.resolver.ctx assignment (no longer needed)
- Confirmed instruction_lower.py uses context=owner.context throughout
- Added phase132_multifunc_isolation_min.hako test for multi-function isolation
- Extended phase132_exit_phi_parity.sh with Case C (Rust VM context test)

Testing:
- Phase 132 smoke test: All 3 cases PASS
- Phase 87 LLVM exe test: PASS (Result: 42)
- STRICT mode: PASS
- No regressions: Behavior identical before/after (RC:6 maintained)

Impact:
- Reduced manual context management complexity
- FunctionLowerContext now sole source of truth (SSOT)
- Per-function state properly isolated, no cross-function collisions
- Cleaner architecture: context parameter passed explicitly vs manual dict

a15d1e97e6 refactor(llvm): Phase 132-P1 follow-up - bind block_end_values and clear predeclared PHIs 2025-12-15 11:47:58 +09:00
nyash-codex
e0fb6fecf6 refactor(llvm): Phase 132-P1 - FunctionLowerContext Box isolation 
Structural fix for cross-function state leakage bugs discovered in Phase 131-132.

Problem:
- Function-local state (block_end_values, def_blocks, phi_manager, caches)
  was globally managed, causing collisions across functions
- Required manual clearing via _clear_function_local_state() (~80 lines)
- Tuple-key workaround (func_name, block_id) added complexity

Solution: FunctionLowerContext Box
- Encapsulates all function-scoped state in a dedicated Box
- Automatic lifetime management (created at entry, destroyed at exit)
- Eliminates manual state clearing
- Simplifies from tuple-key to simple block_id access

Implementation:
1. Created src/llvm_py/context/function_lower_context.py (150+ lines)
   - block_end_values, def_blocks, jump_only_blocks
   - phi_manager, resolver_caches
   - Helper methods: get/set_block_snapshot(), register_def(), etc.

2. Updated function_lower.py
   - Creates context at function entry
   - Binds resolver to context for cache isolation
   - Removed _clear_function_local_state() (~80 lines)

3. Updated block_lower.py
   - Changed tuple-key (func_name, block_id) to simple block_id
   - Access via context.get_block_snapshot() / context.set_block_snapshot()

4. Updated resolver.py, phi_wiring/wiring.py, phi_wiring/tagging.py
   - All state access now through context

5. Fixed critical bug in phi_wiring/tagging.py
   - setup_phi_placeholders() was breaking context connection
   - Changed reassignment to .clear()/.update() to preserve reference

Benefits:
- ✅ Automatic state isolation (no manual clearing)
- ✅ Clear ownership (one context per function)
- ✅ Eliminated tuple-keys (simpler code)
- ✅ Prevents bugs by design (cross-function leakage impossible)

Test results:
- ✅ Phase 87 smoke test: PASS
- ✅ Phase 132 smoke test: PASS (both cases)
- ✅ STRICT mode: Works with multi-function inputs
- ✅ No regression

Files modified: 8 (2 new, 6 updated)

11e794d0ff feat(llvm): Phase 132-P1 - Function-local state clearing at function boundaries 
## Problem
Multiple function-scoped caches used (bid, vid) or similar keys without
function namespace, causing cross-function collisions.

## Affected State (now cleared at function start)

1. **PhiManager.predeclared** - (bid, vid) -> phi_value
2. **Resolver caches**:
   - i64_cache, ptr_cache, f64_cache - (bb_name, vid) -> value
   - _end_i64_cache - (bid, vid) -> value
3. **String caches** - string_ids, string_literals, string_ptrs, etc.
4. **Control flow** - _jump_only_blocks, block_phi_incomings, def_blocks

## Solution (Box-First principle)

Added `_clear_function_local_state(builder)` called at start of each
`lower_function()`. This ensures:

- Each function starts with clean state
- No cross-function ValueId/BlockId collisions
- PHI generation determinism improved

## Implementation

**File**: src/llvm_py/builders/function_lower.py

```python
def _clear_function_local_state(builder):
    """Clear all function-local state at function boundary."""
    if hasattr(builder, 'phi_manager'):
        builder.phi_manager.predeclared.clear()
    # ... clear all caches ...
```

## Design Principles

- **Box-First**: Each function is an isolated Box
- **SSOT**: Function-local state is scoped to function
- **Fail-Fast**: Collision structure eliminated by design

3f58f34592 feat(llvm): Phase 132-P0 - block_end_values tuple-key fix for cross-function isolation 
## Problem
`block_end_values` used block ID only as key, causing collisions when
multiple functions share the same block IDs (e.g., bb0 in both
condition_fn and main).

## Root Cause
- condition_fn's bb0 → block_end_values[0]
- main's bb0 → block_end_values[0] (OVERWRITES!)
- PHI resolution gets wrong snapshot → dominance error

## Solution (Box-First principle)
Change key from `int` to `Tuple[str, int]` (func_name, block_id):

```python
# Before
block_end_values: Dict[int, Dict[int, ir.Value]]

# After
block_end_values: Dict[Tuple[str, int], Dict[int, ir.Value]]
```

## Files Modified (Python - 6 files)

1. `llvm_builder.py` - Type annotation update
2. `function_lower.py` - Pass func_name to lower_blocks
3. `block_lower.py` - Use tuple keys for snapshot save/load
4. `resolver.py` - Add func_name parameter to resolve_incoming
5. `wiring.py` - Thread func_name through PHI wiring
6. `phi_manager.py` - Debug traces

## Files Modified (Rust - cleanup)

- Removed deprecated `loop_to_join.rs` (297 lines deleted)
- Updated pattern lowerers for cleaner exit handling
- Added lifecycle management improvements

## Verification

- ✅ Pattern 1: VM RC: 3, LLVM Result: 3 (no regression)
- ⚠️ Case C: Still has dominance error (separate root cause)
  - Needs additional scope fixes (phi_manager, resolver caches)

## Design Principles

- **Box-First**: Each function is an isolated Box with scoped state
- **SSOT**: (func_name, block_id) uniquely identifies block snapshots
- **Fail-Fast**: No cross-function state contamination

## Known Issues (Phase 132-P1)

Other function-local state needs same treatment:
- phi_manager.predeclared
- resolver caches (i64_cache, ptr_cache, etc.)
- builder._jump_only_blocks

447d4ea246 feat(llvm): Phase 132 - Pattern 1 exit value parity fix + Box-First refactoring 
## Phase 132: Exit PHI Value Parity Fix

### Problem
Pattern 1 (Simple While) returned 0 instead of final loop variable value (3)
- VM: RC: 3 ✅ (correct)
- LLVM: Result: 0 ❌ (wrong)

### Root Cause (Two Layers)
1. **JoinIR/Boundary**: Missing exit_bindings → ExitLineReconnector not firing
2. **LLVM Python**: block_end_values snapshot dropping PHI values

### Fix
**JoinIR** (simple_while_minimal.rs):
- Jump(k_exit, [i_param]) passes exit value

**Boundary** (pattern1_minimal.rs):
- Added LoopExitBinding with carrier_name="i", role=LoopState
- Enables ExitLineReconnector to update variable_map

**LLVM** (block_lower.py):
- Use predeclared_ret_phis for reliable PHI filtering
- Protect builder.vmap PHIs from overwrites (SSOT principle)

### Result
- ✅ VM: RC: 3
- ✅ LLVM: Result: 3
- ✅ VM/LLVM parity achieved

## Phase 132-Post: Box-First Refactoring

### Rust Side
**JoinModule::require_function()** (mod.rs):
- Encapsulate function search logic
- 10 lines → 1 line (90% reduction)
- Reusable for Pattern 2-5

### Python Side
**PhiManager Box** (phi_manager.py - new):
- Centralized PHI lifecycle management
- 47 lines → 8 lines (83% reduction)
- SSOT: builder.vmap owns PHIs
- Fail-Fast: No silent overwrites

**Integration**:
- LLVMBuilder: Added phi_manager
- block_lower.py: Delegated to PhiManager
- tagging.py: Register PHIs with manager

### Documentation
**New Files**:
- docs/development/architecture/exit-phi-design.md
- docs/development/current/main/investigations/phase132-llvm-exit-phi-wrong-result.md
- docs/development/current/main/phases/phase-132/

**Updated**:
- docs/development/current/main/10-Now.md
- docs/development/current/main/phase131-3-llvm-lowering-inventory.md

### Design Principles
- Box-First: Logic encapsulated in classes/methods
- SSOT: Single Source of Truth (builder.vmap for PHIs)
- Fail-Fast: Early explicit failures, no fallbacks
- Separation of Concerns: 3-layer architecture

### 1) Rust MIR Builder (ops.rs + lifecycle.rs)
- OperandTypeClass で型分類（String/Integer/Unknown）
- BinOp 型推論: Integer + Unknown → Integer
- lifecycle.rs に repropagate_binop_types() パス追加
  - PHI 型解決後に BinOp 型を再計算

### 2) JSON Emission (mir_json_emit.rs)

9e76173c99 fix(llvm): Phase 131-5 完了 - TAG-LINK 修正（ExternCall symbol mapping） 
Phase 131-5: ExternCall Symbol Mapping 修正

問題:
- Case B (loop_min_while.hako) が TAG-LINK で失敗
- エラー: undefined reference to `nyash_console_log`

根本原因:
- Python harness が dot → underscore 変換を実行
  (`nyash.console.log` → `nyash_console_log`)
- NyKernel は `nyash.console.log` をエクスポート
  （ELF format では dot が有効）

修正:
- src/llvm_py/instructions/externcall.py から変換ロジックを削除（-4 lines）
- Symbol 名は NyKernel exports と完全一致

変更ファイル:
- src/llvm_py/instructions/externcall.py:
  - 不要な dot→underscore 変換削除
  - ELF symbol 仕様のコメント追加

テスト結果:
- Case B LINK: ❌→✅ (修正成功)
- Case B RUN: ❌ (新 TAG-RUN: infinite loop)
- Case A/B2: ✅ (退行なし)

箱化モジュール化:
- ✅ SSOT 達成: NyKernel exports を信頼
- ✅ クリーンな修正: 不要コード削除のみ
- 推奨: NyKernel symbol naming convention ドキュメント化

Next: Phase 131-6 (TAG-RUN 修正 - infinite loop)

Phase 131-4 P1: PHI After Terminator Bug 修正

問題:
- LLVM IR で PHI が terminator の後に出現（LLVM invariant 違反）
- Case B (loop_min_while.hako) が TAG-EMIT で失敗

修正:
- Multi-pass block lowering architecture 実装:
  - Pass A: non-terminator instructions のみ emit
  - Pass B: PHI finalization（block head に確実に配置）
  - Pass C: deferred terminators を最後に emit

変更ファイル:
- src/llvm_py/builders/block_lower.py (~40行):
  - lower_blocks() で terminator を defer
  - lower_terminators() 新設（Pass C）
  - _deferred_terminators dict で管理
- src/llvm_py/builders/function_lower.py (3行):
  - Pass 順序更新: A→B→C
- src/llvm_py/instructions/ret.py (5行):
  - _disable_phi_synthesis flag で Pass C 中の PHI 生成を抑制

テスト結果:
- Case B EMIT: ❌→✅ (修正成功)
- Case B LINK: ❌ (新 TAG-LINK: undefined nyash_console_log)
- Case A/B2: ✅ (退行なし)

箱化モジュール化:
- ✅ Multi-pass で責務分離
- ✅ Flag mechanism で構造的制御
- ✅ ハードコード禁止原則遵守

Next: Phase 131-5 (TAG-LINK 修正)

e4eedef34f feat(llvm): Phase 132 - Fix PHI instruction ordering bug 
Structural fix for LLVM backend PHI placement issue discovered in Phase 131.

Changes:
- Modified ensure_phi() to position PHI before existing instructions
- Enhanced setup_phi_placeholders() with debug mode
- Created phi_placement.py utility for validation
- Added test script for representative cases

Technical approach:
- PHI creation during setup (before block lowering)
- Explicit positioning with position_before(instrs[0])
- Debug infrastructure via NYASH_PHI_ORDERING_DEBUG=1

Design principles:
- PHI must be created when blocks are empty
- finalize_phis only wires, never creates
- llvmlite API constraints respected

Phase 132 complete. Ready for Phase 133 (ConsoleBox integration).

d7b8f79a75 feat(phase131): LLVM backend re-enable & PHI ordering bug discovery 
Phase 131: JoinIR → LLVM individual fixes (minimal scope)

## Modifications

### 1. LLVM Backend Re-enable ✅
- Built with --features llvm to enable real LLVM execution
- Verified Python/llvmlite environment (llvmlite 0.45.1)
- Fixed llvmlite deprecated API: removed llvm.initialize() call
- Successfully moved from Mock backend to real LLVM harness execution

### 2. PHI Instruction Ordering Bug Discovery ⚠️
- Discovered critical bug: PHI nodes placed AFTER terminator instructions
- LLVM IR constraint: PHI must be at block start, before any non-PHI
- Root cause: finalize_phis() in llvm_builder.py emits PHIs after block termination
- Affects all 6 tests with control flow merges

### 3. ConsoleBox LLVM Integration ⚠️
- Confirmed ConsoleBox not registered in Rust VM environment
- Deferred to Phase 132 (prerequisite issue)

## Results

Modified files:
- src/llvm_py/llvm_builder.py: Removed deprecated llvm.initialize()
- docs/development/current/main/phase130_joinir_llvm_baseline.md: Added Phase 131 results
- CURRENT_TASK.md: Added Phase 131 completion report

Test results:
- ✅ peek_expr_block.hako: LLVM execution success (Result: 1)
- ❌ 6/7 tests: PHI ordering bug (requires Phase 132 refactoring)

## Success Criteria

- ✅ LLVM backend minimal re-enable (1/7 test passing)
- ⚠️ PHI ordering bug discovered and documented
- ⚠️ ConsoleBox integration deferred to Phase 132

## Phase 132 Handoff

Priority 1: Fix PHI instruction ordering bug (finalize_phis() refactoring)
Priority 2: Resolve ConsoleBox registration issue
Priority 3: Enable remaining test cases for LLVM

419214a5a9 feat(naming): Python NamingHelper実装 - Rust NamingBoxのミラー完成 
Phase 25.4 メンテナンス: Python LLVM側のNamingBox SSOT統一

## 📦 実装内容

### 1. Python NamingHelper作成
- 新規作成: `src/llvm_py/naming_helper.py`
- Rust `src/mir/naming.rs` と完全同一の意味論を実装
- 3つの関数:
  - `encode_static_method(box_name, method, arity)` → "BoxName.method/arity"
  - `canonical_box_name(raw)` → "main" → "Main"
  - `normalize_static_global_name(func_name)` → "main._nop/0" → "Main._nop/0"
- doctest 9個全てPASS ✅

### 2. Python LLVM側の統一修正
- `instructions/boxcall.py:437` - f"Main.{method_name}/{arity}" → encode_static_method()
- `instructions/call.py:170-173` - traced_names タプル生成をNamingHelper経由に変更
- `pyvm/intrinsic.py:17, 50` - "Main.esc_json/1", "Main.dirname/1" → encode_static_method()
- `builders/entry.py:16` - 'Main.main/1' → encode_static_method("Main", "main", 1)

## 🎯 技術的成果
- **意味論一致**: Rust ↔ Python で完全同一の命名規則
- **保守性向上**: ハードコード4箇所 → NamingHelper一元管理
- **テスト完備**: doctest 9個でRust NamingBoxと同一動作を保証

## テスト結果
✅ python3 -m py_compile: 全ファイル構文OK
✅ python3 -m doctest naming_helper.py: 9 tests passed

## 参考
- Phase 25.4-A (Rust側): fa9cea51, bceb20ed
- Rust NamingBox SSOT: src/mir/naming.rs
