9ea15e8417 feat(mir): Loop Canonicalizer Phase 4 - router parity verification 
## Summary
既存 Router と Canonicalizer の選択が一致することを dev-only で検証。
不一致は理由付き Fail-Fast（strict mode）。

## Changes
- src/mir/builder/control_flow/joinir/routing.rs:
  - verify_router_parity() 実装
  - cf_loop_joinir_impl でパリティチェック呼び出し
  - 2つのユニットテスト追加
    - test_parity_check_mismatch_detected
    - test_parity_check_match_simple_while
- docs/development/current/main/phases/phase-137/phase-137-4-parity-verification.md:
  - Phase 4 完全ドキュメント

## Verification Modes
- Debug mode (HAKO_JOINIR_DEBUG=1): ログのみ
- Strict mode (HAKO_JOINIR_STRICT=1): 不一致でエラー

## Known Mismatch
- skip_whitespace pattern:
  - Canonicalizer: Pattern3IfPhi (構造認識)
  - Router: Pattern2Break (has_break優先)
  - Phase 5+ で分類ルール改善予定

## Tests
- Unit tests: 2 tests PASS
- Integration: skip_whitespace parity mismatch 検出確認
- cargo test --release --lib: 1046/1046 PASS

Phase 137-4 complete

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

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 ✅

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

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

b7f7882558 feat(joinir): Phase 79 Activation - BindingId wiring operational (dev-only) 
Phase 79 の最終段階：BindingId を ExprLowerer に配線し、end-to-end で動作確認。

Key changes:
- ExprLowerer wiring:
  - scope_resolution.rs: build_condition_env_from_scope_with_binding() (BindingId-aware)
  - expr_lowerer.rs: lower_condition() uses BindingId priority lookup

- ConditionEnv extension:
  - register_loop_var_binding(): Loop var BindingId→ValueId registration
  - register_condition_binding(): Condition-only carrier BindingId→ValueId registration

- Pattern2 integration:
  - pattern2_with_break.rs: Loop var registration (Line 116-128)
  - pattern2_with_break.rs: Carrier role-based registration (Line 381-425)
  - Debug logging: [phase79] tags for registration, [binding_pilot/hit] for lookup success

- E2E tests (normalized_joinir_min.rs, debug-only):
  - test_phase79_digitpos_bindingid_lookup_works(): DigitPos pattern verification
  - test_phase79_trim_bindingid_lookup_works(): Trim pattern verification

Result: BindingId lookup actually works end-to-end
- Promoted carriers resolve via BindingId, not string hacks
- Debug: NYASH_JOINIR_DEBUG=1 shows [phase79] Registered loop var BindingId, [binding_pilot/hit] BindingId(1) -> ValueId(100)

Tests: 1025/1025 lib PASS
Design: dev-only feature-gated, dual-path maintained (BindingId priority + name fallback)

Phase 74-79 complete: BindingId migration fully operational
- Infrastructure (74-76): BindingId type, binding_map, 3-tier lookup, promoted_bindings map
- Implementation (77): DigitPos/Trim populate, legacy deprecate
- Refactoring (78-79 Refactoring): PromotedBindingRecorder, Detector/Recorder split
- Activation (80 Foundation + 79 Activation): CarrierBindingAssigner + ExprLowerer wiring

8b48bec962 feat(joinir): Phase 78 - BindingId infrastructure for promoted carriers (dev-only) 
Phase 78 adds infrastructure to assign BindingIds to synthetic promoted
carriers (e.g., is_digit_pos, is_ch_match), enabling type-safe promoted
variable lookup without string-based naming conventions.

Key Changes:
1. CarrierVar.binding_id field (dev-only):
   - Added Option<BindingId> to track BindingId for each carrier
   - Updated all constructors and struct instantiations

2. CarrierBindingAssigner Box (new file, 273 lines):
   - Allocates BindingIds for promoted carriers via builder.allocate_binding_id()
   - Records original → promoted mapping in promoted_bindings
   - Sets binding_id field on promoted CarrierVar
   - Includes 3 comprehensive unit tests

3. ConditionEnv.register_carrier_binding() (new method):
   - Registers carrier BindingId → ValueId mappings
   - Enables type-safe lookup via binding_id_map

4. Logging cleanup:
   - Gated 6 eprintln! statements with NYASH_JOINIR_DEBUG
   - Unified logging tags to [binding_pilot/*]

Design Decisions:
- Promoters create CarrierInfo, lowering code assigns BindingIds
- CarrierBindingAssigner called from Pattern2/4 lowering (has builder access)
- Clear documentation prevents misuse (promoters lack builder access)

Files modified (18):
- carrier_info.rs: binding_id field added to CarrierVar
- carrier_binding_assigner.rs: New Box for BindingId allocation
- condition_env.rs: register_carrier_binding() method
- mod.rs: Module exports
- pattern2_with_break.rs, pattern4_with_continue.rs: Updated for binding_id
- loop_body_*_promoter.rs: Logging cleanup + binding_id in structs
- phase78-bindingid-promoted-carriers.md: Architecture documentation

Tests: 970/970 PASS (zero regressions)
Status: Infrastructure complete, integration deferred to Phase 79

Next Phase: Wire CarrierBindingAssigner in Pattern2/4 lowering + E2E tests

- Pattern2/4: Wired binding_map from builder.binding_map to promoters
- Legacy deprecation: Added #[deprecated] to resolve_promoted_join_id()
- Dual-path design: BindingId priority + name fallback maintained

Files modified (8):
- pattern2_with_break.rs, pattern4_with_continue.rs: binding_map wiring
- trim_loop_lowering.rs: Trim promoter integration
- carrier_info.rs: Deprecation warnings
- scope_manager.rs: Deprecated fallback paths
- loop_body_carrier_promoter.rs: Trim binding_map support
- loop_body_cond_promoter.rs: Orchestrator updates
- loop_body_digitpos_promoter.rs: DigitPos binding_map support

Tests: 958/958 PASS (zero regressions)
Design: Type-safe BindingId mapping replaces string-based promoted variable resolution

Phase 78+ will delete deprecated code (~50 lines) and make binding_map required.

db9c9055fa obs(joinir): Phase 72 - PHI Reserved Region Observation Complete 
## Summary
Observed PHI dst ValueId distribution to determine if verifier can enforce
reserved region (0-99). **Conclusion: Verifier strengthening NOT recommended.**

## Key Finding
PHI dst allocation does NOT architecturally respect reserved region:
- PHI dst comes from `builder.next_value_id()` (host MirBuilder)
- Reserved region (0-99) is a JoinValueSpace contract for JoinIR lowering
- These are separate allocation pools with no enforcement mechanism
- Current stability is accidental (ValueId allocation ordering)

## Evidence
Manual verification (`apps/tests/loop_min_while.hako`):
- PHI dst = %3 (ValueId(3)) ✅ in reserved region
- Works because PHI allocated early in function (0-20 typical)
- JoinValueSpace allocates high (100+, 1000+)
- Accidental separation, not enforced

## Implementation
Added observation infrastructure (debug-only):
- `src/mir/join_ir/verify_phi_reserved.rs` (266 lines)
  - PHI dst observer with distribution analyzer
  - Region classifier (Reserved/Param/Local)
  - Human-readable report generator
- Instrumentation at PHI allocation points:
  - loop_header_phi_builder.rs:94, 151
  - Debug-only `observe_phi_dst()` calls

## Test Results
- Unit tests: ✅ 4/4 PASS (verify_phi_reserved module)
- Lib tests: ✅ 950/950 PASS, 56 ignored
- Normalized tests: ✅ 54/54 PASS
- Manual verification: ✅ PHI dst in 0-99 observed

## Decision: Document, Don't Enforce
**Rationale**:
1. No architectural mechanism to enforce PHI dst ∈ [0, 99]
2. Adding verifier creates false assumptions about allocation order
3. Current system stable through separate pools (950/950 tests)
4. Future architectural fix possible (Phase 73+) but not urgent

## Documentation
- PHASE_72_SUMMARY.md: Executive summary and implementation record
- phase72-phi-reserved-observation.md: Detailed findings and analysis
- CURRENT_TASK.md: Phase 72 completion entry

## Next Steps
- Phase 73: Update architecture overview with Phase 72 findings
- Optional: Explicit PHI reserved pool (future enhancement)
