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

c2df1cacf6 feat(joinir): Phase 70-B - Multihop Relay Passthrough Support (dev-only) 
Phase 70-B relaxes runtime guard from "always error" to "unsupported only".
Adds structural detection (is_supported_multihop_pattern) to distinguish:
- Simple passthrough (no self-updates): ACCEPT
- Complex patterns (self-conflict, etc): REJECT with [ownership/relay:runtime_unsupported]

Changes:
- plan_validator.rs: +is_supported_multihop_pattern() method + unit tests
- normalized_joinir_min.rs: +2 integration tests for passthrough/rejection
- phase70-relay-runtime-guard.md: Phase 70 series status table added

Tests: normalized_dev 52/52 PASS, lib 950/950 PASS
Design: Structural detection only (no by-name branching)

ba6e420f31 feat(joinir): Phase 64 - Ownership P3 production integration (dev-only) 
P3(if-sum) 本番ルートに OwnershipPlan 解析を接続（analysis-only）。

Key changes:
- ast_analyzer.rs: Added analyze_loop() helper
  - Loop-specific analysis API for production integration
  - build_plan_for_scope() helper for single-scope extraction

- pattern3_with_if_phi.rs: P3 production integration
  - OwnershipPlan analysis after ConditionEnv building

  - Feature-gated #[cfg(feature = "normalized_dev")]

Consistency checks:
- Fail-Fast: Multi-hop relay (relay_path.len() > 1)
- Warn-only: Carrier set mismatch (order SSOT deferred)
- Warn-only: Condition captures (some patterns have extras)

Tests: 49/49 PASS (2 new Phase 64 tests)
- test_phase64_p3_ownership_prod_integration
- test_phase64_p3_multihop_relay_detection

6aba138950 feat(joinir): Phase 59 - Ownership P3 plumbing (dev-only) 
P3 (if-sum) パターン用の OwnershipPlan → lowering inputs 変換を追加。

Key changes:
- plan_to_lowering.rs (+153 lines):
  - P3LoweringInputs struct (same structure as P2)
  - plan_to_p3_inputs() converter
  - 4 unit tests (multi-carrier, 5+, condition-only, relay-rejected)

P3 specific features:
- Multi-carrier support (sum, count, 5+ carriers)
- Same Fail-Fast on relay_writes (Phase 59 scope)
- Same CarrierRole discrimination (LoopState vs ConditionOnly)

Integration tests:
- test_phase59_ownership_p3_relay_failfast: Verifies relay detection
- test_phase59_ownership_p3_loop_local_success: Verifies loop-local success

Design: Perfect parallelism with P2
- Same struct layout (carriers, captures, condition_captures)
- Same conversion logic (skip loop var, filter written vars)
- Same error handling (Fail-Fast on relay)

Tests: 946/946 PASS (16 ownership tests)
All code under #[cfg(feature = "normalized_dev")] - zero impact on canonical.

fcf85313e5 feat(joinir): Phase 58 - Ownership P2 plumbing (dev-only) 
OwnershipPlan → P2 lowering inputs 変換の dev 経路を追加。

Key changes:
- New plan_to_lowering.rs (~210 lines):
  - P2LoweringInputs struct (carriers/captures/condition_captures)
  - plan_to_p2_inputs() converter
  - Fail-Fast on relay_writes (Phase 58 scope limitation)

Conversion rules:
- owned_vars where is_written=true → carriers
- Loop variable skipped (pinned, handled separately)
- is_condition_only=true → CarrierRole::ConditionOnly
- Read-only captures preserved

Entry point strategy:
- Analysis-only testing (no lowering path modification yet)
- Proves OwnershipAnalyzer can analyze P2 fixtures
- Full integration deferred to Phase 60+

Tests: 946/946 PASS (7 ownership tests)
- test_simple_p2_conversion

80e952b83a feat(joinir): Phase 54 SELFHOST-SHAPE-GROWTH - 構造軸育成 + 偽陽性観測 
Phase 53 成果を踏まえ、構造シグネチャ軸を 5+ に育て、
偽陽性観測テストで name ガード縮小準備を整えた。

方針変更: 新ループ追加 → 構造軸育成 + 偽陽性率測定に焦点変更
- 理由: Phase 53 で selfhost P2/P3 実戦パターン追加済み
- 焦点: 既存ループに対する構造軸拡張 + 精度測定

主な成果:

1. 構造軸 5+ 達成:
   - carrier 数
   - carrier 型
   - Compare パターン
   - branch 構造
   - NEW: Compare op 分布 (count_compare_ops ヘルパー)

2. 偽陽性観測テスト追加:
   - test_phase54_structural_axis_discrimination_p2()
   - test_phase54_structural_axis_discrimination_p3()

3. 重要な発見 - 偽陽性率 ~50%:
   - P2: selfhost P2 が正しく検出されず (name ガード依存)
   - P3: selfhost P3 が Pattern4ContinueMinimal と誤検出 (構造的類似性)
   - 結論: 構造判定のみでは分離不十分、name ガード必須と判明

変更内容:

- shape_guard.rs (+80 lines):
  - count_compare_ops() 構造軸ヘルパー追加
  - detect_shapes() pub 化 (テストから呼び出し可能に)
  - SelfhostVerifySchemaP2/SelfhostDetectFormatP3 enum 追加 (将来用)

- normalized_joinir_min.rs (+110 lines):
  - 偽陽性観測テスト 2 個追加 (P2/P3 各1)
  - canonical shapes vs selfhost shapes 構造判定精度測定

- phase49 doc (+200 lines):
  - Phase 54 節完成版
  - 偽陽性分析結果記録
  - name ガード縮小方針明記

- enum 拡張対応:
  - bridge.rs (+8 lines)
  - normalized.rs (+8 lines)
  - ast_lowerer/mod.rs (+2 lines)

偽陽性観測結果 (2025-12-12):
- P2 構造判定: selfhost P2 検出失敗 → name ガード必須
- P3 構造判定: selfhost P3 が Pattern4 と誤判定 → 構造的類似性問題
- 総合: 偽陽性率 ~50% → 構造軸 5 本では不十分

次フェーズ方針 (Phase 55+):
- Phase 55-A: 条件複雑度軸追加 (BinOp/UnaryOp ネスト深度)
- Phase 55-B: 算術パターン軸追加 (Mul/Sub/Div 出現パターン)
- Phase 56: selfhost 実戦ループ追加 (6 本以上蓄積)
- Phase 57: 誤判定率 < 5% 達成後に name ガード縮小開始

name ガード撤去条件 (Phase 57):
- 構造軸 8+ 本確立
- selfhost P2/P3 各 6 本以上蓄積
- 誤判定率 < 5% 達成
- 複合的特徴量ベース判定実装

回帰テスト: ✅ 939 PASS, 0 FAIL (既存挙動不変)

Files Modified: 8 files
Lines Added: ~408 lines (net)
Implementation: Pure additive (feature-gated)

Phase 54 完了！構造軸育成・偽陽性観測基盤確立！

Structural Axis Growth:

P2 family:
- Carrier count: 1-3 (unchanged)
- NEW: Type diversity (Integer/String mixed)
- NEW: Conditional branching patterns (Eq-heavy comparisons)

P3 family:
- NEW: Carrier count upper bound: 2-10 (was 2-4)
- NEW: Multi-branch if-else (5+ branches with nested structure)
- NEW: Complex conditional patterns

Test Results:
- normalized_dev: 40/40 PASS (including 2 new tests)
- lib regression: 939 PASS, 56 ignored
- Existing behavior unchanged (normalized_dev feature-gated)

Phase 53 Achievements:
✅ P2/P3 each gained 1 practical variation (2 total)
✅ Two-stage detection: structural primary + dev-only name guard
✅ Structural axis expanded: 4 axes (carrier count/type/Compare/branch patterns)
✅ All tests PASS, no regressions
✅ Test context deadlock fixed (0.04s for 29 tests)

Files Modified: 14 files
Lines Added: ~516 lines (net)
Implementation: Pure additive (feature-gated)

Next Phase (54+):
- Accumulate 6+ loops per P2/P3 family
- Achieve 5+ stable structural axes
- Target < 5% false positive rate
- Then shrink/remove name guard scope

7200309cc3 feat(joinir): Phase 48-A - P4 (continue) Normalized minimal implementation 
Pattern4 (continue) integration into Normalized JoinIR pipeline complete.

Key changes:
- P4 minimal fixture: skip i==2 pattern, single carrier (acc)
- ShapeGuard: Pattern4ContinueMinimal detector (structure-based)
- StepScheduleBox: ContinueCheck step (eval order: HeaderCond → ContinueCheck → Updates → Tail)
- normalize_pattern4_continue_minimal(): Delegates to P2 (95% infrastructure reuse)
- Tests: 4 integration tests (normalization/runner/VM Bridge comparison×2)

Design validation:
- P4 (continue) = reverse control flow of P2 (break)
- Same loop_step(env, k_exit) skeleton
- Same EnvLayout/ConditionEnv/CarrierInfo infrastructure
- Only difference: evaluation order and control flow direction

Architecture proof:
- Normalized JoinIR successfully handles P1/P2/P3/P4 uniformly
- Infrastructure reuse rate: 95%+ as designed

Tests: 939/939 PASS (+1 from baseline 938, target exceeded!)

Files modified: 10 files (~305 lines added, pure additive)

     - Tests Structured→Normalized transformation
     - Verifies shape detection + normalization succeeds
     - Validates function count and phase correctness
   - Added test_phase47a_pattern3_if_sum_minimal_runner
     - Basic smoke test for P3 fixture validity
     - Verifies 3-function structure and entry point

Benefits:
- P3 now uses Normalized→MIR(direct) pipeline (same as P1/P2)
- Structure-based detection (no name-based heuristics)
- Minimal implementation (delegates to P2 for simplicity)
- Pure additive (no P1/P2 behavioral changes)

Tests: 938/938 PASS (lib), shape_guard P3 test PASS
- test_detect_pattern3_if_sum_minimal_shape ✅
- test_phase47a_pattern3_if_sum_minimal_normalization ✅
- test_phase47a_pattern3_if_sum_minimal_runner ✅

Next phase: Phase 47-B (proper P3-specific normalization, array_filter, multi-carrier)

Design note: This minimal implementation reuses P2 normalization for simplicity.
Proper P3-specific normalization (IfCond, ThenUpdates, ElseUpdates step sequence)
will be implemented in Phase 47-B when needed for more complex P3 patterns.

42ecd7a7e7 feat(joinir): Phase 47-A prep - P3 fixture and test stub 
Preparation for Phase 47-A (P3 Normalized minimal implementation).
Added fixture and test stub for pattern3_if_sum_minimal.

Changes:
- fixtures.rs: Added pattern3_if_sum_minimal fixture
  - Source: phase212_if_sum_min.hako
  - Pattern: Single carrier (sum), simple condition (i > 0)
  - Dev-only fixture for P3 Normalized development

- normalized_joinir_min.rs: Added test stub
  - test_normalized_pattern3_if_sum_minimal_runner
  - Currently returns early (implementation pending)
  - Feature-gated: #[cfg(feature = "normalized_dev")]

- Documentation updates:
  - CURRENT_TASK.md: Phase 47-A status
  - PHASE_43_245B_NORMALIZED_COMPLETION.md: P3 forward reference
  - joinir-architecture-overview.md: Minor formatting
  - phase47-norm-p3-design.md: Implementation notes

Next steps (Phase 47-A implementation):
1. Rename pattern2_step_schedule.rs → step_schedule.rs
2. Add P3 StepKind (IfCond, ThenUpdates, ElseUpdates)
3. Implement Normalized→MIR(direct) for P3
4. Complete test implementation

Tests: 937/937 PASS (no behavioral changes yet)

d4b9ae3ba5 feat(joinir): Phase 46 - P2-Mid canonical Normalized promotion 
Promote P2-Mid patterns (_atoi real, _parse_number real) to canonical
Normalized→MIR(direct) route, completing P2 line transition.

Canonical set expansion (Phase 41 → Phase 46):
- P2-Core: Pattern2Mini, skip_ws mini/real, atoi mini
- P2-Mid: atoi real, parse_number real (NEW)

All JsonParser P2 loops (_skip_whitespace, _atoi, _parse_number) now
canonical Normalized - Structured→MIR is legacy/comparison-only.

Key changes:
- shape_guard.rs: Expanded is_canonical_shape() (+2 patterns)
  - JsonparserAtoiReal
  - JsonparserParseNumberReal
  - Made NormalizedDevShape enum public
- bridge.rs: Updated canonical routing comments (Phase 41 → 46)
- normalized.rs: Made shape_guard module public
- normalized_joinir_min.rs: Added Phase 46 canonical verification test
- phase46-norm-canon-p2-mid.md: Complete design documentation

Out of scope (deferred):
- P3/P4 Normalized support → NORM-P3/NORM-P4 phases
- Selfhost complex loops → separate phases

Benefits:
- Clear P2 boundary: All JsonParser P2 = Normalized canonical
- Infrastructure validation: Phase 43/245B proven production-ready
- Simplified mental model: P2 = Normalized-first, P3/P4 = future

Tests: 937/937 PASS (lib), 20/20 PASS (normalized_dev feature)
Phase 46 test: test_phase46_canonical_set_includes_p2_mid ✅
