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

4ef2261e97 fix(joinir): Phase 269 P1.2 - static call normalization for this.method() 
Problem:
- `this.method()` calls in static box loops were using string constant "StringUtils" as receiver
- This violated Box Theory (static box this should not be runtime object)
- Pattern8 was trying to pass receiver to JoinIR, causing SSA/PHI issues

Solution (3-part fix):
1. **MeResolverBox Fail-Fast** (stmts.rs): Remove string fallback, error message cleanup
2. **ReceiverNormalizeBox** (calls/build.rs): Normalize `this/me.method()` → static call at compile-time
3. **Pattern8 Skip Static Box** (pattern8_scan_bool_predicate.rs): Reject Pattern8 for static box contexts

Key changes:
- **stmts.rs**: Update error message - remove MeBindingInitializerBox mentions
- **calls/build.rs**: Add This/Me receiver check, normalize to static call if current_static_box exists
- **calls/lowering.rs**: Remove NewBox-based "me" initialization (2 locations - fixes Stage1Cli regression)
- **pattern8_scan_bool_predicate.rs**: Skip Pattern8 for static boxes (use Pattern1 fallback instead)

Result:
- ✅ phase269_p1_2_this_method_in_loop_vm.sh PASS (exit=7)
- ✅ No regression: phase259_p0_is_integer_vm PASS
- ✅ No regression: phase269_p0_pattern8_frag_vm PASS
- ✅ Stage1Cli unit tests PASS
- ✅ MIR uses CallTarget::Global, no const "StringUtils" as receiver

5f22fe8fcd feat(pattern8): Phase 269 P1 - SSA fix and call_method type annotation 
Phase 269 P1.0: Pattern8 SSA correctness
- Add PHI node for loop variable `i` in pattern8_scan_bool_predicate.rs
- Ensure proper SSA form: i_current = phi [(preheader, i_init), (step, i_next)]
- Create loop_predicate_scan.rs for Pattern8 Frag emission
- Pre-allocate PHI destination before block generation
- Use insert_phi_at_head_spanned() for span synchronization

Phase 269 P1.1: call_method return type SSOT propagation
- Add callee_sig_name() helper in annotation.rs for function name formatting
- Annotate call_method return types in emit_unified_call_impl()
- Use module signature as SSOT for return type resolution (no hardcoding)
- Arity-aware function name: "BoxName.method/arity"

Fixes: is_integer() now correctly returns Bool instead of String
Test: Simple call_method test returns exit=7 (loop test has pre-existing bug)
Unit tests: All 1389 tests passing

be4de67601 fix(joinir): improve Pattern3 classification to exclude simple conditional assignment (Phase 264 P0) 
Problem:
- Pattern3 heuristic was too conservative: detect_if_in_body() returned
  true for ANY if statement, causing simple conditional assignments to be
  misclassified as Pattern3IfPhi
- Example: `if i == 0 then seg = "first" else seg = "other"` was routed
  to Pattern3, but Pattern3 only handles if-sum patterns like
  `sum = sum + (if x then 1 else 0)`
- This caused loops with conditional assignment to fail Pattern3 check
  and exhaust all routing paths

Solution (Conservative, Phase 264 P0):
- ast_feature_extractor.rs:
  - detect_if_else_phi_in_body(): Always return false
  - has_if = has_if_else_phi (don't use detect_if_in_body())
- loop_pattern_detection/mod.rs:
  - Add has_if_sum_signature() (returns false for P0)
  - has_if_else_phi = carrier_count > 1 && has_if_sum_signature(scope)

Effect:
- Simple conditional assignment loops now fall through to Pattern1 ✅
- Pattern3 misrouting prevented ✅

Results:
- Lib tests: 1368/1368 PASS (no regression)
- Minimal repro: phase264_p0_bundle_resolver_loop_min.hako PASS ✅
- Quick smoke: 45/46 (unchanged - complex BundleResolver loop needs P1)

Phase 264 P1 TODO:
- Implement accurate if-sum signature detection (AST/CFG analysis)
- Support complex nested loops in Pattern2 or new pattern

93022e7e10 fix(pattern2): abort entire Pattern2 on unpromoted LoopBodyLocal instead of partial execution 
Phase 263 P0: Pattern2 で処理できない LoopBodyLocal を検出したら Pattern2 全体を早期終了

Changes:
- promote_step_box.rs: 戻り値を Result<Option<_>, String> に変更
  - Reject を二分化: 対象外（not_readonly等）→ Ok(None)、対象だが未対応 → Err
- pattern2_lowering_orchestrator.rs: Ok(None) 検出で早期 return
- apps/tests/phase263_p0_pattern2_seg_min.hako: test simplification

後続経路（legacy binding等）へ fallback させる（detection→extract→lower SSOT 維持）
Fail-Fast 原則: 対象外は Ok(None) で後続経路へ、対象だが未対応は Err で即座に失敗

Fixes: core_direct_array_oob_set_rc_vm smoke test FAIL

a767f0f3a9 feat(joinir): Phase 259 P0 - Pattern8 BoolPredicateScan + Copy binding fix 
Pattern8 (Boolean Predicate Scan) implementation for is_integer/1:
- New pattern detection for `loop + if not predicate() { return false }`
- JoinIR lowerer with main/loop_step/k_exit structure
- Me receiver passed as param (by-name 禁止)

Key fixes:
1. expr_result = Some(join_exit_value) (Pattern7 style)
2. Tail-call: dst: None (no extra Ret instruction)
3. instruction_rewriter: Add `&& is_loop_header_with_phi` check
   - Pattern8 has no carriers → no PHIs → MUST generate Copy bindings
   - Without this, ValueId(103/104/105) were undefined

Status: Copy instructions now generated correctly, but exit block
creation issue remains (next step: Step A-C in指示書).

edc7355937 refactor(joinir): unify boundary join_inputs SSOT (pattern4/6/7) 
Apply Phase 256.8 SSOT fix to Pattern4/6/7:
- Use join_module.entry.params.clone() instead of hardcoded ValueIds
- Add fail-fast validation for params count mismatch
- Remove ValueId(0), ValueId(PARAM_MIN + k) patterns
- Clean up unused PARAM_MIN imports

This prevents entry_param_mismatch errors structurally and maintains
consistency with Pattern2/3.

Changes:
- pattern4_with_continue.rs: Lines 442-476 (SSOT extraction + validation)
- pattern6_scan_with_init.rs: Lines 447-471 (SSOT extraction + validation)
- pattern7_split_scan.rs: Lines 495-526 (SSOT extraction + validation)

All patterns now use the same SSOT principle:
1. Extract entry function (priority: join_module.entry → fallback "main")
2. Use params as SSOT: join_inputs = entry_func.params.clone()
3. Build host_inputs in expected order (pattern-specific)
4. Fail-fast validation: join_inputs.len() == host_inputs.len()

Verification:
- cargo build --release: ✅ PASS (no PARAM_MIN warnings)
- Quick profile: ✅ First FAIL still json_lint_vm (baseline maintained)
- Pattern6 smoke: ✅ PASS (index_of test)
- Pattern7 smoke: Pre-existing phi pred mismatch (not introduced by SSOT)

64f679354a fix(joinir): Phase 256 P1 - Carrier PHI wiring and parameter mapping (in progress) 
**Status**: Core carrier PHI issue partially resolved, debugging loop body

**Progress**:
✅ Task 1: split_scan_minimal.rs Carriers-First ordering (6 locations)
✅ Task 2: pattern7_split_scan.rs boundary configuration (host/join inputs, exit_bindings, expr_result)
✅ Result now flows from k_exit to post-loop code (RC issue resolved)
⚠️  Loop body instruction execution needs review

**Key Fixes**:
1. Fixed host_inputs/join_inputs to match main() params Carriers-First order
2. Added result to exit_bindings (CarrierRole::LoopState)
3. Added result back to loop_invariants for variable initialization
4. Added expr_result=join_exit_value_result for loop expression return
5. Fixed jump args to k_exit to include all 4 params [i, start, result, s]

**Current Issue**:
- Loop body type errors resolved (String vs Integer fixed)
- New issue: Loop body computations (sep_len) undefined in certain blocks
- Likely cause: JoinIR→MIR conversion of local variables needs review

**Next Steps**:
- Review JoinValueSpace allocation and ValueId mapping in conversion
- Verify loop_step instruction ordering and block structure
- May need to refactor bound computation or revisit split algorithm

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

9336785680 feat(anf): Phase 146/147 - Loop/If Condition ANF with Compare support 
## Phase 146 P0: ANF Routing SSOT Unified

**Goal**: Unify ANF routing in `lower_expr_with_scope()` L54-84, remove legacy lowering

**Changes**:
- expr_lowerer_box.rs: Added scope check (PureOnly → skip ANF, WithImpure → try ANF)
- post_if_post_k.rs: Removed legacy inline lowering (L271-285), added `lower_condition_legacy()` helper
- contract.rs: Already had `CondLoweringFailed` out-of-scope reason

**Test Results**: ✅ Phase 146 P0 smoke (exit 7), 0 regressions

## Phase 146 P1: Compare Operator Support

**Goal**: Enable ANF for condition expressions with Compare operators

**Changes**:
- joinir_dev.rs: Added `anf_allow_pure_enabled()` (HAKO_ANF_ALLOW_PURE=1)
- expr_lowerer_box.rs: PureOnly scope ANF support (L56-66)
- execute_box.rs: Compare operator support (+122 lines)
  - `execute_compare_hoist()`, `execute_compare_recursive()`, `ast_compare_to_joinir()`
  - Extended `normalize_and_lower()` for Compare

**Test Results**: ✅ Phase 146 P1 smoke (exit 7 with flags), 0 regressions

## Phase 147 P0: Recursive Comparison ANF

**Goal**: Extend recursive ANF to Compare operators

**Changes**:
- contract.rs: Added `AnfParentKind::Compare` variant
- plan_box.rs: Compare case in BinaryOp routing (L68-79, L134-139)
  - Distinguishes Compare vs arithmetic BinaryOp

**Benefits**: Enables recursive ANF for comparisons
- `s.length() == 3` → `t = s.length(); if (t == 3)` ✅
- `s1.length() < s2.length()` → `t1 = s1.length(); t2 = s2.length(); if (t1 < t2)` ✅

275fe45ba4 feat(normalization): Phase 142 P0 - Statement-level normalization 
## Summary

Changed normalization unit from "block suffix" to "statement (loop only)"
to prevent pattern explosion.

## Changes

1. **PlanBox** (`plan_box.rs`):
   - Always return `loop_only()` for any `loop(true)`, regardless of what follows
   - Subsequent statements (return, assignments) handled by normal MIR lowering
   - ~70 lines reduced, 7 unit tests updated

2. **build_block** (`stmts.rs`):
   - Removed `break` after consumed=1 from suffix_router
   - Continue processing subsequent statements normally
   - Phase 142 P0 comments added

3. **Tests**:
   - Fixture: `phase142_loop_stmt_only_then_return_length_min.hako`
   - VM smoke: exit code 3 (s="abc" → s.length() → 3)

## Results

- ✅ Unit tests: 10/10 passed
- ✅ Phase 142 VM smoke: PASS
- ✅ Phase 131 regression: PASS
- ✅ Build: Success

## Design

- **Pattern Explosion Prevention**: Normalize only the loop (consumed=1)
- **Out-of-Scope Policy**: Always Ok(None) for fallback
- **Fail-Fast**: Only for "in-scope but broken" cases

91c7dfbf0b refactor(normalization): Phase 135 P0 - Extend plan to zero post-loop assigns 
Generalize NormalizationPlan suffix detection to accept zero post-loop assignments:

Goal: Improve entry point consistency by allowing `loop + assign* + return` (N >= 0)

Implementation:
- Modified plan_box.rs detection logic (only file changed)
- Removed `post_assign_count >= 1` requirement
- Unified Phase 131 (loop + return) and Phase 132-133 (loop + assign+ + return) paths

Changes:
- src/mir/builder/control_flow/normalization/plan_box.rs:
  - Removed assignment count constraint
  - Unified pattern detection: `loop + assign* + return` (N >= 0)
- apps/tests/phase135_loop_true_break_once_post_empty_return_min.hako (new fixture)
- tools/smokes/v2/profiles/integration/apps/phase135_*.sh (new smoke tests)

Pattern support:
- Phase 131/135: loop + return only (consumed: 2, post_assign_count: 0) ✅
- Phase 132: loop + 1 assign + return (consumed: 3, post_assign_count: 1) ✅
- Phase 133: loop + N assigns + return (consumed: 2+N, post_assign_count: N) ✅

Design principles maintained:
- **Minimal change**: Only plan_box.rs modified (execute_box unchanged)
- **SSOT**: Detection logic centralized in plan_box.rs
- **Box-First**: Responsibility separation preserved (Plan/Execute)

Test results:
- Unit tests (plan_box): 9/9 PASS (2 new tests added)
- Phase 135 VM/LLVM EXE: PASS (exit code 1)
- Phase 131 regression: 2/2 PASS (path now unified)
- Phase 133 regression: 2/2 PASS
- cargo test --lib: PASS

Benefits:
- Unified entry point for all loop + post patterns
- Easier maintenance (single detection logic)
- Future extensibility (easy to add new patterns)
- Clear separation of Phase 131 and Phase 132-135 paths

Default behavior unchanged: Dev-only guard maintained

ef71ea955c feat(control_tree): Phase 133 P0 - Multiple post-loop assigns support 
Extend Phase 132's loop(true) + post-loop to accept multiple assignments:

Goal: `x=0; loop(true){ x=1; break }; x=x+2; x=x+3; return x` → exit code 6

Implementation:
- Extended loop_true_break_once.rs pattern detection (len() == 2 → len() >= 2)
- Added iterative assignment lowering (for loop over post_nodes)
- Reused Phase 130's lower_assign_stmt for each assignment
- Maintained ExitMeta DirectValue mode (PHI-free)

Changes:
- apps/tests/phase133_loop_true_break_once_post_multi_add_min.hako (new fixture)
- tools/smokes/v2/profiles/integration/apps/phase133_*_multi_add_*.sh (new smokes)
- src/mir/control_tree/normalized_shadow/loop_true_break_once.rs (+30 lines)
- docs/development/current/main/phases/phase-133/README.md (new documentation)
- docs/development/current/main/10-Now.md (Phase 133 entry added)

Scope (Phase 130 baseline):
- ✅ x = <int literal>
- ✅ x = y (variable copy)
- ✅ x = x + <int literal> (increment)
- ❌ Function calls / general expressions (future phases)

Design principles:
- Minimal change: ~30 lines added
- SSOT preservation: env_post_k remains single source of truth
- Reuse: Leveraged existing lower_assign_stmt
- Fail-Fast: Contract violations trigger freeze_with_hint

Test results:
- cargo test --lib: 1176 PASS
- Phase 133 VM: PASS (exit code 6)
- Phase 133 LLVM EXE: PASS (exit code 6)
- Phase 132 regression: PASS (exit code 3)
- Phase 131 regression: PASS (exit code 1)
- Phase 97 regression: PASS

Architecture maintained:
- 5-function structure unchanged (main/loop_step/loop_body/k_exit/post_k)
- PHI-free DirectValue mode
- Zero changes to ExitMeta, merge logic, or JoinIR contracts

b5d8ace6ab feat(control_tree): Phase 132 P0 + P0.5 - loop(true) + post-loop support 
**Phase 132 P0**: Extend loop(true) break-once to support post-loop statements

Goal: Support `loop(true) { x = 1; break }; x = x + 2; return x` → exit code 3

Implementation:
- loop_true_break_once.rs: Add post_k continuation generation
- Reuse Phase 130's lower_assign_stmt for post statements
- ExitMeta uses DirectValue mode (PHI-free)

**Phase 132 P0.5**: Fix StepTree post-loop statement visibility

Root cause: routing.rs created StepTree from Loop node only, losing post statements

Solution:
- New: normalized_shadow_suffix_router_box.rs
- Detects block suffix: Loop + Assign* + Return
- Creates StepTree from entire suffix (Block([Loop, Assign, Return]))
- Modified build_block() to call suffix router (dev-only)

Changes:
- apps/tests/phase132_loop_true_break_once_post_add_min.hako (new fixture)
- tools/smokes/v2/profiles/integration/apps/phase132_loop_true_break_once_post_add_*.sh
- src/mir/control_tree/normalized_shadow/loop_true_break_once.rs (+150 lines)
- src/mir/builder/control_flow/joinir/patterns/policies/normalized_shadow_suffix_router_box.rs (+380 lines)
- src/mir/builder/stmts.rs (build_block modified to support suffix skipping)

Design principles:
- StepTree unchanged: Block is SSOT for statement order
- No data duplication: Loop doesn't hold post_nodes
- Suffix router handles detection + conversion
- build_block() handles wiring only

Test results:
- Phase 132 VM: PASS (exit code 3)
- Phase 131 regression: PASS
- Phase 97 regression: PASS

ed38aa820a test: Phase 116 if-only keep+call merge parity (VM + LLVM EXE) 
Phase 116 固定: if-only で片側が元値保持、片側が call 結果の merge パターン

## 実装内容

### Fixture
- `apps/tests/phase116_if_only_keep_plus_call_min.hako`
- Expected output: `10\n2`
- Pattern:
  - then側: call結果でvを更新 (`v = f(1)`)
  - else側: 元の値を保持 (`v = 10`)
  - merge地点: 異なるソース（元値 vs call結果）からのPHI

### Smoke Tests
- `phase116_if_only_keep_plus_call_vm.sh` - VM parity
  - output_validator.sh で数値2行 `10\n2` を検証
  - `NYASH_DISABLE_PLUGINS=1 HAKO_JOINIR_STRICT=1`
- `phase116_if_only_keep_plus_call_llvm_exe.sh` - LLVM EXE parity
  - llvm_exe_runner.sh を利用（plugin dlopen/cache/build-all SSOT）
  - llvm_exe_build_and_run_numeric_smoke で検証

## 検証結果

✅ VM smoke: PASS (10\n2)
✅ LLVM EXE smoke: PASS (10\n2)
✅ 回帰 (Phase 115): PASS (2\n3)

## 技術的詳細

### JoinIR Pattern 1 (Simple If)

```
entry_block:
  v = 10
  if flag == 1 goto then_block else exit_block

then_block:
  v = f(1)
  goto exit_block

exit_block:
  v_merged = PHI [v=10 from entry, v=f(1) from then]
  print(v_merged)
```

### PHI接続の重要性
- entry → exit: 元値 (`10`) を直接伝播
- then → exit: call結果 (`f(1)`) を伝播
- PHI: 異なる型のソース（変数 vs call結果）を正しくmerge

LLVM IRでは、これらが適切な型で統一される必要がある。

## Box-First原則の適用

✅ 既存の箱化されたコンポーネントを活用
  - output_validator.sh による出力検証の統一
  - llvm_exe_runner.sh によるLLVM実行の標準化
  - テストインフラの再利用（no reinvention）

## Fail-Fast原則

✅ VM/LLVM両方でエラーを即座に検出
  - `HAKO_JOINIR_STRICT=1` で厳密な検証
  - フォールバック処理なし（エラーは明示的に失敗）

- LLVM EXE smoke: phase115_if_only_call_merge_llvm_exe.sh
  - llvm_exe_runner.sh を利用した標準パリティ検証

**検証結果**:
- VM test: PASS ✅
- LLVM EXE test: PASS ✅
- Phase 114 regression: PASS ✅

**箱化モジュール化の観点**:
- 単一責任: 各smokeは1パターンのみ検証（call result merge）
- 分離: VM/LLVM EXEで独立したテスト（llvm_exe_runner.sh経由）
- Fail-Fast: HAKO_JOINIR_STRICT=1 で不正な制御フローを即座に検出

**関連**:
- Phase 103: If-Only基本パリティ（制御フロー基礎）
- Phase 113: If-Only部分代入パリティ（変数マージ）
- Phase 114: If-Only return+post パリティ（early returnとpost-if文）
- Phase 115: If-Only call result merge パリティ（関数呼び出し結果マージ） ← 今回
