58f66e3fa2 feat(mir): Phase 137-5 - Decision Policy SSOT化完了 
## 目的
Canonicalizer の RoutingDecision.chosen を「lowerer 選択の最終結果」にする
（構造クラス名ではなく ExitContract ベースの決定）

## 実装内容

### 1. Canonicalizer の決定ロジック修正
- `src/mir/loop_canonicalizer/mod.rs`
  - `skip_whitespace` パターン認識で ExitContract (has_break=true) を考慮
  - Pattern3IfPhi → Pattern2Break に修正（構造は似ているが break あり）
  - 単体テスト更新（Pattern2Break 期待に変更）

### 2. Parity 検証テスト修正
- `src/mir/builder/control_flow/joinir/routing.rs`
  - `test_parity_check_mismatch_detected` → `test_parity_check_skip_whitespace_match`
  - Canonicalizer と Router の一致を検証（ミスマッチ検出からマッチ検証へ）
  - Phase 137-5 の SSOT 原則を反映

### 3. ドキュメント更新
- `docs/development/current/main/design/loop-canonicalizer.md`
  - Phase 137-5: Decision Policy SSOT セクション追加
  - ExitContract 優先の原則を明記
  - skip_whitespace の例を追加

- `docs/development/current/main/phases/phase-137/README.md`
  - Phase 4 完了マーク追加
  - Phase 5 完了セクション追加（実装・検証・効果）

## 検証結果
- ✅ 単体テスト: `cargo test --release --lib loop_canonicalizer::tests` (11/11 passed)
- ✅ Parity テスト: `cargo test --release --lib 'routing::tests::test_parity'` (2/2 passed)
- ✅ Strict モード: `HAKO_JOINIR_STRICT=1` で skip_whitespace parity OK

## 効果
- Router と Canonicalizer の pattern 選択が一致
- ExitContract が pattern 決定の SSOT として明確化
- 構造的特徴（if-else 等）は notes に記録（将来拡張に備える）

2bdf1abe78 feat(mir): Phase 1 - Loop Canonicalizer type definitions 
Implements the foundation for loop canonicalization - a preprocessing
layer that decomposes AST loops into normalized skeleton representation
to prevent combinatorial explosion in pattern detection.

## Implementation (Phase 1)

Created `src/mir/loop_canonicalizer/mod.rs` with:

1. **Core Types**:
   - `LoopSkeleton`: Canonical loop representation
   - `SkeletonStep`: Step kinds (HeaderCond, BreakCheck, ContinueCheck, Update, Body)
   - `UpdateKind`: Carrier update classification (ConstStep, Conditional, Arbitrary)
   - `ExitContract`: Exit presence tracking (break/continue/return)
   - `CarrierSlot`: Loop variables with roles and update rules
   - `CarrierRole`: Semantic roles (Counter, Accumulator, ConditionVar, Derived)
   - `CapturedSlot`: Outer scope variable capture

2. **Capability Guard**:
   - `RoutingDecision`: Pattern selection with diagnostics
   - `capability_tags` module: Standardized Fail-Fast vocabulary
     (CAP_MISSING_CONST_STEP, CAP_MISSING_SINGLE_BREAK, etc.)

3. **Helper Methods**:
   - Skeleton counting (break_checks, continue_checks)
   - Carrier name extraction
   - Exit contract queries
   - Display implementations for debugging

4. **Unit Tests**: 6 tests covering all basic functionality

## Design Principles

- **Input**: AST only (no JoinIR dependencies)
- **Output**: LoopSkeleton only (no BlockId/ValueId)
- **Boundary**: Clear separation from lowering concerns
- **Fail-Fast**: Capability-based rejection with clear reasons

## Next Steps (Not in this commit)

- Phase 2: `LoopCanonicalizer::canonicalize(ast) -> Result<LoopSkeleton>`
- Phase 3: Test with skip_whitespace fixture
- Phase 4: Integration with existing JoinIR lowering

## Acceptance Criteria

✅ `cargo build --release` succeeds
✅ `cargo test --release --lib` passes (1039 tests)
✅ 6 new unit tests for loop_canonicalizer pass
✅ No regressions in existing tests

455d511187 feat(mir): Phase 136 P0 - ValueId allocator SSOT 徹底（関数内経路から value_gen.next() 掃討） 
## Summary
Eliminates remaining `value_gen.next()` calls from function-context code paths,
unifying all ValueId allocation through `MirBuilder::next_value_id()` SSOT allocator.

## Changes

### 1. Fixed `new_typed_value()` (src/mir/builder.rs:1068)
**Before**: `let id = self.value_gen.next();` (bypasses function context)
**After**: `let id = self.next_value_id();` (respects function context)

This is a public API used in function context, so must use SSOT allocator
to avoid collisions with reserved PHI dsts and function params.

### 2. Fixed test code (src/mir/builder.rs)
**test_shadowing_binding_restore** (lines 1161, 1171):
- Simulates function scope with `push_lexical_scope()`
- Changed to `builder.next_value_id()` for function scope simulation

**test_valueid_binding_parallel_allocation** (lines 1196-1216):
- Tests ValueId/BindingId independence
- Changed to `builder.next_value_id()` with note that Module context fallback preserves test intent

### 3. Verified Module context fallbacks (OK, no change needed)
These already check `current_function.is_some()` and use `value_gen.next()` only as Module context fallback:
- `src/mir/builder/utils.rs:43` - next_value_id() SSOT implementation
- `src/mir/builder/utils.rs:436` - pin_to_slot()
- `src/mir/builder/utils.rs:467` - materialize_local()
- `src/mir/utils/phi_helpers.rs:69` - insert_phi_unified()

## Verification
```bash
rg -n "value_gen\.next\(" src/mir --type rust | grep -v "Module context" | grep -v "//"
# Result: Only comments/docs remain
```

## Acceptance
✅ cargo test --release --lib - 997 passed
✅ phase135_trim_mir_verify.sh - PASS
✅ phase132_exit_phi_parity.sh - 3/3 PASS
✅ All function-context `value_gen.next()` eliminated

## Effect
- **Collision prevention**: No more ValueId collisions between function-level allocations and reserved PHI dsts
- **SSOT compliance**: All ValueId allocation flows through single allocator
- **Contract enforcement**: Phase 135 P1 contract_checks will catch violations immediately

22b0c14adb feat(joinir): Phase 135 P1 - Contract checks Fail-Fast (二度と破れない設計) 
## Summary
Adds early Fail-Fast contract verification to prevent Phase 135 P0 issues from recurring.
Two new verifiers catch allocator SSOT violations and boundary inconsistencies before --verify.

## Changes

### Step 1: verify_condition_bindings_consistent
**Location**: `src/mir/builder/control_flow/joinir/merge/contract_checks.rs`

**Contract**: condition_bindings can have aliases (multiple names for same join_value),
but same join_value with different host_value is a violation.

**Example Error**:
```
[JoinIRVerifier/Phase135-P1] condition_bindings conflict:
  join_value ValueId(104) mapped to both ValueId(12) and ValueId(18)
```

**Catches**: ConditionLoweringBox bypassing SSOT allocator before BoundaryInjector

### Step 2: verify_header_phi_dsts_not_redefined
**Location**: `src/mir/builder/control_flow/joinir/merge/contract_checks.rs`

**Contract**: Loop header PHI dst ValueIds must not be reused as dst in non-PHI instructions.
Violation breaks MIR SSA (PHI dst overwrite).

**Example Error**:
```
[JoinIRVerifier/Phase135-P1] Header PHI dst ValueId(14) redefined by non-PHI instruction in block 3:
  Instruction: Call { dst: Some(ValueId(14)), ... }
```

**Catches**: ValueId collisions between header PHI dsts and lowered instructions

### Integration
**Location**: `src/mir/builder/control_flow/joinir/merge/mod.rs`

Added to `verify_joinir_contracts()`:
1. Step 1 runs before merge (validates boundary)
2. Step 2 runs after merge (validates func with PHI dst set)

### Documentation
- Updated `phase135_trim_mir_verify.sh` - Added P1 contract_checks description
- Updated `phase-135/README.md` - Added P1 section with contract details and effects

## Acceptance
✅ Build: SUCCESS
✅ Smoke: phase135_trim_mir_verify.sh - PASS
✅ Regression: phase132_exit_phi_parity.sh - 3/3 PASS
✅ Regression: phase133_json_skip_whitespace_llvm_exe.sh - PASS

## Effect
- **Prevention**: Future Box implementations catch SSOT violations immediately
- **Explicit Errors**: Phase 135-specific messages instead of generic --verify failures
- **Unbreakable**: Debug builds always detect violations, enforced by CI/CD

d82c332a40 feat(joinir): Phase 135 P0 - ConditionLoweringBox allocator SSOT (ValueId collision fix) 
## Summary
Root cause: ConditionLoweringBox was bypassing ConditionContext.alloc_value (SSOT allocator),
causing ValueId collisions between JoinIR condition params and lowered instructions.

## Changes
1. **ConditionLoweringBox (expr_lowerer.rs)**: Must use ConditionContext.alloc_value
   - Pass &mut ConditionContext to lower_condition (SSOT allocator)
   - Eliminates internal counter usage

2. **Allocator unification (condition_lowerer.rs, method_call_lowerer.rs)**:
   - Accept &mut dyn FnMut() -> ValueId as allocator parameter
   - Ensures all lowering paths use same SSOT allocator

3. **Boundary Copy deduplication (joinir_inline_boundary_injector.rs)**:
   - Deduplicate condition_bindings by dst
   - Fail-Fast if different sources target same dst (MIR SSA violation)

4. **Trim pattern fixes (trim_loop_lowering.rs, trim_pattern_validator.rs, stmts.rs)**:
   - Use builder.next_value_id() instead of value_gen.next() in function context
   - Ensures function-level ValueId allocation respects reserved PHI dsts

## Acceptance
✅ ./target/release/hakorune --verify apps/tests/phase133_json_skip_whitespace_min.hako
✅ Smoke: phase135_trim_mir_verify.sh - MIR SSA validation PASS
✅ Regression: phase132_exit_phi_parity.sh - 3/3 PASS
✅ Regression: phase133_json_skip_whitespace_llvm_exe.sh - compile-only PASS

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

771bf6b0d1 feat(joinir): Phase 132-P3 - Exit PHI collision early detection 
Added verify_exit_phi_no_collision() to contract_checks.rs for early detection
of ValueId collisions between exit PHIs and other instructions.

Problem detected:
- If exit_phi_builder uses builder.value_gen.next() (module-level) instead of
  func.next_value_id() (function-level), ValueIds can collide:

  Example:
  - bb0: %1 = const 0   (counter init)
  - bb3: %1 = phi ...   (exit PHI - collision!)

Previous behavior:
- Error only detected at LLVM backend runtime
- Cryptic error: "Cannot overwrite PHI dst=1"

New behavior:
- Panic at Rust compile time (debug build)
- Clear error message with fix suggestion:
  "Exit PHI dst %1 collides with instruction in block 0
   Fix: Use func.next_value_id() in exit_phi_builder.rs"

Benefits:
- 🔥 Fail-Fast: Catch errors during Rust compilation, not LLVM execution
- 📋 Clear messages: Exact collision point + fix suggestion
- 🧪 Testable: verify_exit_phi_no_collision() can be unit tested

bd07b7f41f fix(joinir): Phase 132-P2 - Exit PHI ValueId collision fix 
Root cause: exit_phi_builder.rs used builder.value_gen.next() (module-level counter)
instead of func.next_value_id() (function-level counter) for allocating exit PHI dst.

This caused ValueId collisions in functions like:
- bb0: %1 = const 0  (initial counter value)
- bb3: %1 = phi ...  (exit PHI - collision!)

The LLVM backend then failed with:
"Cannot overwrite PHI dst=1. ValueId namespace collision detected."

Fix: Use func.next_value_id() to allocate from the function's local counter,
ensuring unique ValueIds within each function.

Verified:
- Pattern 1 (simple while): VM RC:3, LLVM RC:3 ✅
- Case C (Pattern 5): VM returns 3, LLVM Result: 3 ✅

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

18d56d5b88 refactor(joinir): Box-First cleanup - trace unification + SSOT + Fail-Fast 
## Changes

### 1. eprintln! to trace.rs unification
**File**: src/mir/builder/control_flow/joinir/routing.rs
- Replaced direct eprintln! with trace::trace().routing()
- Box-First principle: Log responsibility centralized in trace.rs
- Enables filtering via HAKO_JOINIR_DEBUG=1

### 2. Priority field removal (SSOT)
**File**: src/mir/builder/control_flow/joinir/patterns/router.rs
- Removed #[allow(dead_code)] priority field
- Array order is SSOT (Single Source of Truth) for pattern priority
- Pattern try order: Pattern5 → Pattern4 → Pattern3 → Pattern1 → Pattern2
- Eliminated dead code warning

### 3. catch_unwind removal (Fail-Fast)
**File**: src/mir/builder/control_flow/joinir/routing_legacy_binding.rs
- Removed catch_unwind + Ok(None) silent error swallowing
- Fail-Fast principle: Panics propagate explicitly
- Enables early detection of panic sources

## Verification

✅ Build: cargo build --release (0 errors)
✅ Tests: 71 JoinIR tests all PASS
✅ VM: /tmp/p1_return_i.hako → Result: 3
✅ LLVM: /tmp/p1_return_i.hako → Mock exit code: 0

## Design Principles Applied

- **Box-First**: Log responsibility → trace.rs
- **SSOT**: Array order defines priority (no redundant field)
- **Fail-Fast**: Explicit failures, no silent error swallowing

## Statistics

- 3 files changed
- 53 deletions, 28 insertions
- Net: -25 lines (code reduction)

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

a955dd6b18 feat(llvm): Phase 131-15 - print/concat segfault 根治修正 
## P1-1/P1-2: TypeFacts 優先化
- binop.py: operand facts が dst_type ヒントより優先
- mir_json_emit.rs: Unknown 時に dst_type を出さない
- function_lower.py: value_types を metadata から読み込み

## P2: handle concat 統一（根治）
- print シグネチャ修正: i64(i64) → void(i8*)
- Mixed concat を handle ベースに統一:
  - concat_si/concat_is → concat_hh
  - box.from_i64 で integer を handle 化
  - Everything is Box 哲学に統一
- legacy 関数は互換性のために保持

## 結果
- ✅ print("Result: " + 3) → Result: 3
- ✅ segfault 解消
- ✅ Everything is Box 統一

d3b3bf5372 feat(mir): Phase 131-11-E - TypeFacts/TypeDemands 分離（SSOT） 
## 実装内容

### 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)
- 結果ベースの dst_type 発行に変更
- Integer → "i64", String → {kind: handle, box_type: StringBox}

### 3) Python LLVM Backend (binop.py)
- dst_type を確実な情報として使用
- dst_type != None なら優先して処理

## 結果
- ✅ MIR: PHI/BinOp が Integer として正しく型付け
- ✅ VM: `Result: 3` （正しい出力）
- ✅ JSON: `dst_type: "i64"` を発行
- ❓ LLVM: 別の codegen 問題の可能性あり

## SSOT 設計達成
- TypeFacts（事実）: 定義命令から推論
- TypeDemands（要求）: 使用箇所の coercion で吸収
- 後方伝播なし: Fail-Fast に統一
