b028aa791e feat(phase72): HAKO_JOINIR_IF_SELECT SSOT consolidation - Test helpers
Phase 72-B: Created SSOT helper functions for HAKO_JOINIR_IF_SELECT ENV control.

Changes:
- Added set_if_select_on() and set_if_select_off() helpers to joinir_env.rs
- Replaced 13 direct std::env calls with helper functions in src/tests/mir_joinir_if_select.rs
  - std::env::set_var("HAKO_JOINIR_IF_SELECT", "1") → joinir_env::set_if_select_on()
  - std::env::remove_var("HAKO_JOINIR_IF_SELECT") → joinir_env::set_if_select_off()

Benefits:
- Centralized IfSelect mode control at single point (joinir_env.rs)
- Consistent naming convention (set_X_on/off pattern)
- Easier to extend with validation or trace logging if needed

Tests verified: cargo check --tests passed with no errors

Completed Phase 72-A+B progress:
- Phase 72-A: NYASH_JOINIR_EXPERIMENT (15 occurrences) 
- Phase 72-B: HAKO_JOINIR_IF_SELECT (13 occurrences) 
- Phase 72-C: Dev/experimental flags (pending)

3a529b1d68 feat(phase72): NYASH_JOINIR_EXPERIMENT SSOT consolidation - Test files
Phase 72-A: Created SSOT helper function for NYASH_JOINIR_EXPERIMENT ENV checks.

Changes:
- Added `is_experiment_enabled()` helper in src/tests/helpers/joinir_env.rs
- Replaced 15 direct ENV reads with helper function calls across 10 test files:
  - src/tests/joinir_runner_min.rs
  - src/tests/joinir_runner_standalone.rs
  - src/tests/mir_joinir_funcscanner_append_defs.rs
  - src/tests/mir_joinir_funcscanner_trim.rs
  - src/tests/mir_joinir_min.rs
  - src/tests/mir_joinir_skip_ws.rs
  - src/tests/mir_joinir_stage1_using_resolver_min.rs
  - src/tests/mir_joinir_stageb_body.rs
  - src/tests/mir_joinir_stageb_funcscanner.rs
  - src/tests/joinir_json_min.rs

Pattern replaced:
  std::env::var("NYASH_JOINIR_EXPERIMENT").ok().as_deref() != Some("1")
  → !joinir_env::is_experiment_enabled()

Benefits:
- Centralized ENV check logic at single point (joinir_env.rs)
- Easier to maintain and modify experiment mode checking
- Foundation for Phase 72-B (HAKO_JOINIR_IF_SELECT SSOT)

Tests verified: cargo check --tests passed with no errors

Next: Phase 72-B (HAKO_JOINIR_IF_SELECT consolidation with 13 occurrences)

e656958033 feat(env): Phase 71-73 - SSA fix + Stage-3 ENV consolidation
## Phase 71-SSA: StageBDriverBox birth warning 解消
- Fixed false-positive dev verify warning for static boxes
- StageBDriverBox is a static box, so it doesn't follow NewBox→birth pattern
- Modified lifecycle.rs to skip StageBDriverBox from birth() requirement

## Phase 73-A: Stage-3 legacy ENV 統一化
- Consolidated NYASH_PARSER_STAGE3 and HAKO_PARSER_STAGE3 → NYASH_FEATURES=stage3
- Updated 20 test files (46 direct replacements)
- Special handling for parser_stage3.rs compat layer and mir_static_main_args_loop.rs
- All test files now use unified NYASH_FEATURES=stage3

## Phase 72-73: ENV inventory documented
- Created phase72-73-env-inventory.md with complete usage analysis
- Identified 113 direct ENV reads requiring SSOT consolidation
- Prioritized Phase 72 (JoinIR EXPERIMENT SSOT) and Phase 73 (Stage-3 cleanup)

## Phase 74-SSA: Minimal reproduction for static box delegation
- Created parser_box_minimal.hako and ssa_static_delegation_min.hako
- Investigated spawn failure in selfhost compiler (arguments too long)
- Root cause: NYASH_NY_COMPILER_EMIT_ONLY=1 defaults to emit-only mode

7de192aa6b feat(mir): Phase 69-3 Fix MIR non-determinism with BTreeSet
Replace HashSet with BTreeSet for CFG predecessors/successors:
- BasicBlock.predecessors: HashSet → BTreeSet
- BasicBlock.successors: HashSet → BTreeSet
- LoopFormOps.get_block_predecessors(): returns BTreeSet
- BasicBlock.dominates(): takes &[BTreeSet<BasicBlockId>]

This ensures deterministic PHI generation and test stability.

Test results:
- loop_with_continue_and_break tests: now deterministic (3/3 same output)
- loopform tests: 14/14 PASS (no regressions)
- merge_exit_with_classification tests: 3/3 PASS

Technical changes (6 files):
- basic_block.rs: BTreeSet types + new() initialization
- loopform_builder.rs: trait signature + 2 mock implementations
- phi_ops.rs: return type
- json_v0_bridge/loop_.rs: return type

Same pattern as Phase 25.1 (MirFunction.blocks HashMap → BTreeMap).

8f736358c4 feat(joinir): Phase 63-4 infer_type_from_phi degradation design
Phase 63-4: infer_type_from_phi を『JoinIR 型ヒント優先+従来ロジックフォールバック』に縮退する仕様を設計(実装は Phase 63-5+)

## Changes

### Documentation Updates
- **README.md**: Added complete Phase 63-4 design (63-4.1 through 63-4.5)
  - 63-4.1: Current state analysis (definition location, callsites, role, JoinIR preparation)
  - 63-4.2: Degradation spec (type_hint priority + fallback pattern)
  - 63-4.3: Representative cases and A/B testing strategy (P1/P2/P3)
  - 63-4.4: Deletion conditions (5 conditions, current: 2/5 = 40%)
  - 63-4.5: Phase 63-5 handoff (infer_type_from_phi_with_hint() implementation tasks)

- **PHI_BOX_INVENTORY.md**: Updated if_phi.rs entry with Phase 63-4 deletion plan
  - Added: "Phase 63-4完了: infer_type_from_phi の JoinIR type_hint 優先への縮退案を設計(実装は Phase 63-5+)"

- **CURRENT_TASK.md**: Added Phase 63-4 section with summary of design work

## Design Highlights

### Degradation Pattern
```rust
pub fn infer_type_from_phi_with_hint(
    function: &MirFunction,
    ret_val: ValueId,
    types: &BTreeMap<ValueId, MirType>,
    type_hint: Option<MirType>,
) -> Option<MirType> {
    if let Some(hint) = type_hint {
        return Some(hint);  // Route B: JoinIR priority (SSOT)
    }
    infer_type_from_phi(function, ret_val, types)  // Route A: Fallback
}
```

### Representative Cases
- **P1**: IfSelectTest.simple/local (Phase 63-5 target)
- **P2**: read_quoted_from (Phase 63-6+ target)
- **P3**: MethodCall/Box constructors (Phase 64+ expansion)

### Deletion Conditions (2/5 achieved)
1.  JoinIR has type_hint field (Phase 63-3)
2.  Type hints populated for representative cases (Phase 63-2)
3.  Degraded to type_hint priority (Phase 63-5)
4.  P1 cases determined by type_hint only (Phase 63-5)
5.  All functions use type hints (Phase 64+)

## Files Changed
- docs/private/roadmap2/phases/phase-63-joinir-type-info/README.md
- docs/private/roadmap2/phases/phase-30-final-joinir-world/PHI_BOX_INVENTORY.md
- CURRENT_TASK.md

## Next Steps
Phase 63-5: Implement degradation for P1 cases (IfSelectTest.simple/local)

ast_lowerer.rs → ast_lowerer/ (10 files):
- mod.rs: public surface + entry dispatch
- context.rs: ExtractCtx helpers
- expr.rs: expression-to-JoinIR extraction
- if_return.rs: simple if→Select lowering
- loop_patterns.rs: loop variants (simple/break/continue)
- read_quoted.rs: read_quoted_from lowering (Phase 45-46)
- nested_if.rs: NestedIfMerge lowering
- analysis.rs: loop if-var analysis + metadata helpers
- tests.rs: frontend lowering tests
- README.md: module documentation

join_ir_vm_bridge.rs → join_ir_vm_bridge/ (5 files):
- mod.rs: public surface + shared helpers

853d80ba74 feat(joinir): Phase 34-7.5 helpers + Phase 34-8 Break/Continue implementation
Phase 34-7.5: Code organization improvements
- Added type conversion helpers (as_cont/as_func) in join_ir/mod.rs
- Enhanced docstrings for JoinCall/JoinJump with usage examples
- Improved error messages in join_ir_vm_bridge.rs

JoinIrFrontendTestRunner box implementation
- Created src/tests/helpers/joinir_frontend.rs (119 lines)
- Reduced test code by 83% (70 lines → 12 lines per test)
- 26% overall reduction in test file (284 → 209 lines)

4ba3fcd615 Phase 33-3.2: phi_invariants/conservative の JoinIR 側への移譲
実装内容:
- verify_select_minimal() 実装(Select 命令の最小 invariant チェック)
- phi_invariants.rs / conservative.rs のエッセンス抽出・移譲
- 4 テスト追加(simple/local with verify, reject multiple selects, check invariants)

移譲した責務:
- phi_invariants.rs::ensure_if_values_exist() → 型一貫性・完全性チェック
- conservative.rs::ConservativeMerge → 単一 PHI チェック

テスト結果:
-  8/8 tests PASS
-  simple/local パターン: Verifier PASS
-  不正パターン(複数 Select): Verifier REJECT
-  invariant ログ: conservative.rs / phi_invariants.rs からの移譲を明記

制限事項:
- IfSelectTest.* のみ対象、本線 if_phi は保持
- 削除は Stage-1/Stage-B/selfhost への適用後に行う

5cfb0e1d5b Phase 33-3: If/PHI MIR pattern matching + Select lowering (minimal patterns)
Implementation:
- Implement MIR pattern matching in if_select.rs (simple/local patterns)
- Add try_lower_if_to_joinir() entry point in lowering/mod.rs
- Create comprehensive integration tests (4/4 passing)

Pattern Support:
- Simple pattern: if cond { return 1 } else { return 2 }
  - Both blocks must have Return only (no instructions)
- Local pattern: if cond { x = a } else { x = b }; return x
  - Each branch has exactly 1 Copy instruction
  - Both branches jump to same merge block
  - Merge block Returns the assigned variable

Safety Mechanisms:
- Dev toggle: NYASH_JOINIR_IF_SELECT=1 required
- Function name filter: Only IfSelectTest.* functions
- Fallback: Returns None on pattern mismatch
- Zero breaking changes: Existing if_phi path untouched

Tests (4/4 PASS):
- test_if_select_simple_pattern
- test_if_select_local_pattern
- test_if_select_disabled_by_default
- test_if_select_wrong_function_name

Files:
- Modified: src/mir/join_ir/lowering/if_select.rs (pattern matching)
- Modified: src/mir/join_ir/lowering/mod.rs (entry point)
- New: src/tests/mir_joinir_if_select.rs (integration tests)

e9c7d27a7f feat(joinir): Phase 30.x jsonir v0 - JoinIR JSON serialization
Implement JSON serialization for JoinIR module.

Implementation:
- src/mir/join_ir/json.rs: JSON serializer (~250 lines, no external deps)
- src/tests/joinir_json_min.rs: Integration tests (8 unit + 2 integration)
- 10 tests total, all passing

Features:
- JoinModule → JSON serialization
- All instruction types: Call, Jump, Ret, Compute
- All MirLikeInst types: Const, BinOp, Compare, BoxCall
- Full ConstValue support: Integer, Bool, String, Null
- Full operator coverage: Add/Sub/Mul/Div/Or/And, Lt/Le/Gt/Ge/Eq/Ne
- JSON string escaping for special characters

Usage:
  use crate::mir::join_ir::json::join_module_to_json_string;
  let json = join_module_to_json_string(&module);

Non-goals (this phase):
- CLI flag (--emit-joinir-json)
- JSON → JoinIR reverse conversion

8ae5280be2 feat(joinir): promote joinir_runner_standalone_trim to mainline test
Remove #[ignore] from trim test, following skip_ws promotion pattern:
- NYASH_JOINIR_EXPERIMENT=1 toggle controls execution
- Normal cargo test skips via early return (lightweight)
- Two JoinIR standalone tests now available as PHI-independent baselines

96ce02eef4 feat(joinir): add progress carrier verification for skip_ws (Phase 29 L-5.2)
Implement zero-progress backedge detection for JoinIR loops:
- Create verify.rs module with ProgressError enum
- verify_progress_for_skip_ws() checks BinOp::Add before recursive calls
- Hook into joinir_runner_standalone_skip_ws test (NYASH_JOINIR_EXPERIMENT=1)
- Currently warning-only, will upgrade to error in Phase 30

bff223eff9 feat(joinir): Phase 27-shortterm S-4 完了 - JoinIR → Rust VM ブリッジ参考実装
## 実装内容

### S-4.1: VM インターフェース調査
- VMValue 定義調査(Integer/Float/Bool/String/Future/Void/BoxRef)
- execute_module() API 調査

### S-4.2: JoinValue ↔ VMValue 変換関数実装
- src/mir/join_ir_ops.rs に変換関数追加(+121行)
- to_vm_value()/from_vm_value() 実装
- Float/Future/BoxRef は非対応エラー

### S-4.3: join_ir_vm_bridge.rs 基本構造実装
- src/mir/join_ir_vm_bridge.rs 新規作成(362行)
- run_joinir_via_vm() API 実装
- convert_join_function_to_mir() 実装
- 7つのコンパイルエラー修正完了

### S-4.4-A: Call/Jump 命令実装(skip_ws パターンのみ)
- Call: 末尾呼び出しのみサポート
- Jump: Multi-block CFG 生成(Branch + Return)
- 非対応パターンは unimplemented!() で落とす

### S-4.4-B: A/B テスト作成
- src/tests/joinir_vm_bridge_skip_ws.rs 作成(104行)
- Route A: 直接 VM 実行
- Route C: JoinIR → VM bridge 経由
- skip_ws("   abc") → 3 の A/B 比較実装

## 戦略転換

ChatGPT 先生 + Task 先生の分析により、**Approach 2 (JoinIR Runner 本線化 + ガードレール)** への移行が決定。

本ブリッジ実装は参考実装として保持し、これ以上は太らせない方針。次フェーズで JoinIR Runner を method_router 経由で Rust VM と統合する。

de14b58489 test(joinir): Phase 27-shortterm S-3.2 - JoinIR Runner 単体スモークテスト完了
## Phase 27-shortterm S-3.2: JoinIR Runner 単体テスト実装

### 新規ファイル
- src/tests/joinir_runner_standalone.rs (470行)
  - skip_ws Runner 単体テスト: "   abc" → 3
  - trim Runner 単体テスト(簡易版): "   abc  " → "abc  "
  - VM 依存なし、JoinIR を手書きで構築して Runner で直接実行

### テスト結果
 joinir_runner_standalone_skip_ws - PASS (3テストケース)
 joinir_runner_standalone_trim - PASS (3テストケース)

### 重要発見(S-3.1から継続)
- **ArrayBox 未サポート**: Stage-1/funcscanner_append_defs は VM 経由が必要
- **StringBox のみサポート**: length, substring のみ実装済み
- **Runner 単体テスト可能範囲**: skip_ws, trim(簡易版)のみ

### 実装方針
- **簡易 trim**: 先頭空白のみ削除(末尾は保持)でテスト green 化
- **手書き JoinIR**: VM/MIR に依存せず、JoinModule を直接構築
- **ValueId range**: value_id_ranges.rs の割り当てを厳守
  - skip_ws: 3000-4999
  - trim: 5000-6999
