in JoinIR lowering, aligning with MIR's lexical scope model.

Design decision: Option A (Parallel BindingId Layer) with gradual migration.
Migration roadmap: Phases 74-77, ~8-12 hours total, zero production impact.

Changes:
- phase73-scope-manager-design.md: SSOT design (~700 lines)
- phase73-completion-summary.md: Deliverables summary
- phase73-index.md: Navigation index
- scope_manager_bindingid_poc/: Working PoC (437 lines, dev-only)

Tests: 6/6 PoC tests PASS, lib 950/950 PASS
Implementation: Parallel layer (no changes to existing code paths)

253eb59b06 obs(joinir): Phase 72 - PHI Reserved Region Observation Complete
Phase 72 investigates whether PHI dst ValueIds adhere to reserved region [0-99].
Conclusion: Current system is stable but relies on accidental non-overlap,
NOT architectural enforcement.

Recommendation: Do NOT strengthen verifier. PHI dst allocated by MirBuilder
(separate from JoinValueSpace reserved contract). Full fix deferred to Phase 73+.

Changes:
- verify_phi_reserved.rs: New observation infrastructure (debug-only)
- phase72-phi-reserved-observation.md: Detailed findings + risk assessment
- PHASE_72_SUMMARY.md: Executive summary
- loop_header_phi_builder.rs: Debug observation hooks
- phase72_phi_observation.rs: Unit tests (6/6 PASS)

Tests: lib 950/950 PASS (no regressions)
Architecture: No production impact (debug-only, feature-gated)

24cc948f61 feat(joinir): Phase 70-C - Merge Relay Detection (dev-only)
Phase 70-C enables detection of merge relay patterns where multiple inner
loops update the same owner-owned variable. This allows compile-time
validation that relay sources can be merged at owner scope's exit PHI.

Changes:
- phase70c-merge-relay.md: New SSOT doc for merge relay semantics
- normalized_joinir_min.rs: +2 integration tests

Tests: normalized_dev 54/54 PASS, lib 950/950 PASS
Design: Validator accepts multiple relays to same owner (individually valid)

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)

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)

5c75506dcc feat(joinir): Phase 66 - Ownership-Relay Multihop Implementation (dev-only)
Phase 65設計に基づき、relay_path.len() > 1 を analysis/plan 層で受理するよう実装。

Key changes:
- plan_to_lowering.rs: relay_path.len() > 1 制限撤去 + 構造的 Fail-Fast 維持
  - relay_path.is_empty() → Err(loop relay は最低 1 hop)
  - relay_path[0] != plan.scope_id → Err(この scope が最初の hop)
  - relay.owner_scope == plan.scope_id → Err(relay と owned は排他)
  - owned_vars ∩ relay_writes ≠ ∅ → Err(同名は不変条件違反)

- ast_analyzer.rs: 3階層 multihop テスト追加
  - multihop_relay_detected_for_3_layer_nested_loops

Unit tests (plan_to_lowering):
- test_relay_multi_hop_accepted_in_with_relay

ba68fb2bad docs(joinir): Phase 65 - Ownership-Relay Multihop Design (設計のみ)
Multihop relay(複数階層を跨ぐrelay)の完全な設計文書を作成。
Phase 66実装の土台となる意味論と不変条件を確立。

Key design decisions:
- Multihop relay 意味論: relay_path(内→外の順)、段階的carrier化
- Merge relay 意味論: PERMIT with owner merge(複数inner loopが同一祖先owned変数を更新)
- Fail-Fast 解除条件: Phase 66実装時の受け入れ基準を明文化
- 実装箇所の特定: Analyzer変更不要、plan_to_lowering/Pattern lowering変更点を箇条書き
- 禁止事項: by-name分岐排除、dev-only name guard対象外

Design principles:
- 「読むのは自由、管理は直下だけ」を維持
- 各中間ループは「素通し」のみ(merge責務はownerのみ)
- Owner scopeのexit PHIで全分岐をmerge
- 構造ベース設計(変数名による特別扱いなし)

Representative cases:
- 3階層multihop(AST例 + OwnershipPlan例)
- Merge relay(JSON fixture例 + 期待されるOwnershipPlan)

Phase 66への引き継ぎ:
- この文書の「5. 実装箇所の特定」をガイドとして使用
- Fail-Fast段階解除の流れに従って実装
- 回帰テスト(既存Phase 64テスト全PASS)を確認しながら進める

Status: 設計完了、実装はPhase 66以降
Tests: N/A (設計文書のみ)

Key changes:
- New analyzer.rs (632 lines):
  - OwnershipAnalyzer: Main analysis engine
  - ScopeKind: Function/Loop/Block/If scope types
  - ScopeInfo: Internal scope representation with reads/writes tracking

Algorithm:
1. Build scope tree (Function/Loop/Block/If hierarchy)
2. Collect reads/writes/condition_reads per scope
3. Apply body-local ownership rule (if/block locals → enclosing Loop/Function)
4. Generate OwnershipPlan: owned_vars, relay_writes, captures, condition_captures

Core invariants enforced:
- Ownership Uniqueness: Each variable has exactly one owner
- Carrier Locality: carriers = writes ∩ owned
- Relay Propagation: writes to ancestor-owned → relay up
- Capture Read-Only: captures have no PHI at this scope

Tests: 7 ownership unit tests + 946 existing (0 regressions)
- test_simple_loop_ownership: relay writes to function
- test_loop_local_carrier: owned AND written = carrier
- test_capture_read_only: read-only captures
- test_nested_loop_relay: relay chains through nested loops

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)

   - Added thread-local test context depth counter
   - Fixed deadlock in nested test_ctx() calls via reentrant with_dev_env_if_unset()

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)

4ecb6435d3 docs(joinir): Phase 48 - Normalized P4 (Continue) design
Complete design documentation for Pattern4 (continue) Normalized support,
extending unified Normalized infrastructure to all 4 loop patterns.

Design documents:
- phase48-norm-p4-design.md: Complete P4 Normalized design (380 lines)
  - Key insight: continue = immediate TailCallFn(loop_step, ...) (no new instruction!)
  - Infrastructure reuse: 95%+ from P2/P3 (only ContinueCheck step kind new)
  - Target loops prioritized:
    - ◎ _parse_array (skip whitespace) - PRIMARY (Phase 48-A)
    - ○ _parse_object (skip whitespace) - Extended
    - △ _unescape_string, _parse_string - Later
  - Control flow: ContinueCheck before Updates (skip processing early)
  - Same EnvLayout/ConditionEnv/CarrierInfo/ExitLine as P2/P3
  - Implementation strategy: dev-only → canonical (proven approach)

Architecture:
- Unified Normalized for P1/P2/P3/P4 (all patterns same pipeline)
- P4 uses loop_step(env, k_exit) skeleton (same as P2/P3)
- continue semantics: TailCallFn = skip to next iteration (CPS natural fit)

Benefits:
- 95% infrastructure reuse from P2/P3
- No new JpInst needed (continue = existing TailCallFn)
- Incremental rollout (dev → canonical)
- Clear semantic: continue = immediate recursion

Implementation roadmap:
- Phase 48-A: Minimal continue (dev-only)
- Phase 48-B: Extended patterns (multi-carrier)
- Phase 48-C: Canonical promotion

Updates:
- joinir-architecture-overview.md: Added Phase 48 section
- CURRENT_TASK.md: Phase 48 entry (Design Complete)
- phase47-norm-p3-design.md: Minor formatting

Status: Design phase complete (doc-only, no implementation yet)

99bdf93dfe feat(joinir): Phase 47-A-LOWERING - P3 Normalized→MIR(direct)
Implement full Pattern3 (if-sum) Normalized→MIR(direct) support, completing
the P3 minimal implementation.

Key changes:

1. P3 Shape Detection (shape_guard.rs):
   - Implemented is_pattern3_if_sum_minimal() with structure-based detection
   - Detects P3 characteristics:
     - Has Compare instruction (loop condition)
     - Has Select instruction (conditional carrier update)
     - Has tail call (Call with k_next: None)
     - Reasonable param count (2-4 for i, sum carriers)
   - Handles both JoinInst::Select and Compute(MirLikeInst::Select)
   - Added unit test: test_detect_pattern3_if_sum_minimal_shape 

2. P3 Normalization Function (normalized.rs):
   - Implemented normalize_pattern3_if_sum_minimal()
   - Guards: Validates Structured JoinIR + P3 shape detection
   - Phase 47-A minimal: Delegates to P2 normalization (works for simple cases)
   - Updated normalized_dev_roundtrip_structured() integration
   - Returns Result<NormalizedModule, String> for proper error handling

3. Bridge Integration (bridge.rs):
   - Updated normalize_for_shape() to call P3 normalization
   - No changes needed to direct.rs (already handles P3 instructions)

4. Integration Tests (normalized_joinir_min.rs):
   - Added test_phase47a_pattern3_if_sum_minimal_normalization
     - 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.

e356524b0a feat(joinir): Phase 246-EX Part 1 - FromHost carrier infrastructure
Extends Phase 247-EX dual-value architecture for _atoi NumberAccumulation
support. Implements FromHost carrier handling throughout JoinIR pipeline.

## Problem Analysis

_atoi requires `result = result * 10 + digit_pos` where:
- digit_pos is promoted to dual carriers: is_digit_pos (bool) + digit_value (int)
- digit_value is used in NumberAccumulation but NOT updated itself
- Existing infrastructure filtered out carriers without updates

## Implementation

### 1. Carrier Filtering (pattern2_with_break.rs:507-514)
**Added FromHost retention**:
```rust
carrier_updates.contains_key(&carrier.name)
    || carrier.role == CarrierRole::ConditionOnly
    || carrier.init == CarrierInit::FromHost  // Phase 247-EX
```

**Effect**: Keeps digit_value carrier despite no update expression

### 2. Carrier Update Passthrough (loop_with_break_minimal.rs:411-426)
**Added FromHost passthrough**:
- FromHost carriers without updates pass through from env
- Similar to Phase 227 ConditionOnly handling
- Logged as `[loop/carrier_update] Phase 247-EX: FromHost carrier passthrough`

### 3. Exit Bindings Collection (meta_collector.rs:156-172)
**Added FromHost exit_bindings inclusion**:
```rust
Some((CarrierRole::LoopState, CarrierInit::FromHost)) => {
    // Include in exit_bindings for latch incoming
    // Not for exit PHI or variable_map
}
```

**Effect**: digit_value gets latch incoming for header PHI

## Test Results

- **Before**: 931 tests PASS
- **After**: 931 tests PASS (0 regressions)

## Verification

**Phase 247-EX UpdateEnv working**:
```
[update_env/phase247ex] Resolved promoted 'digit_pos' → 'digit_value' (integer carrier): ValueId(111)
```

**NumberAccumulation MIR generated**:
```
%39 = %14 Mul %38    ← result * 10
%40 = %39 Add %9     ← tmp + digit_value
```

## Status

-  Pattern2 classification
-  NumberAccumulation detection

8900a3cc44 feat(joinir): Phase 247-EX - DigitPos dual-value architecture
Extends DigitPos promotion to generate TWO carriers for Pattern A/B support:
- Boolean carrier (is_digit_pos) for break conditions
- Integer carrier (digit_value) for NumberAccumulation

## Implementation

1. **DigitPosPromoter** (loop_body_digitpos_promoter.rs)
   - Generates dual carriers: is_<var> (bool) + <base>_value (int)
   - Smart naming: "digit_pos" → "digit" (removes "_pos" suffix)

2. **UpdateEnv** (update_env.rs)
   - Context-aware promoted variable resolution
   - Priority: <base>_value (int) → is_<var> (bool) → standard
   - Pass promoted_loopbodylocals from CarrierInfo

3. **Integration** (loop_with_break_minimal.rs)
   - UpdateEnv constructor updated to pass promoted list

## Test Results

- **Before**: 925 tests PASS
- **After**: 931 tests PASS (+6 new tests, 0 failures)

## New Tests

- test_promoted_variable_resolution_digit_pos - Full dual-value
- test_promoted_variable_resolution_fallback_to_bool - Fallback
- test_promoted_variable_not_a_carrier - Error handling

## Impact

| Pattern | Before | After |
|---------|--------|-------|
| _parse_number |  Works (bool only) |  Works (bool used, int unused) |
| _atoi |  Failed (missing int) |  READY (int carrier available!) |

d4597dacfa feat(joinir): Phase 245C - Function parameter capture + test fix
Extend CapturedEnv to include function parameters used in loop conditions,
enabling ExprLowerer to resolve variables like `s` in `loop(p < s.length())`.

Phase 245C changes:
- function_scope_capture.rs: Add collect_names_in_loop_parts() helper
- function_scope_capture.rs: Extend analyze_captured_vars_v2() with param capture logic
- function_scope_capture.rs: Add 4 new comprehensive tests

Test fix:
- expr_lowerer/ast_support.rs: Accept all MethodCall nodes for syntax support
  (validation happens during lowering in MethodCallLowerer)

Problem solved: "Variable not found: s" errors in loop conditions

Test results: 924/924 PASS (+13 from baseline 911)

d4f90976da refactor(joinir): Phase 244 - ConditionLoweringBox trait unification
Unify condition lowering logic across Pattern 2/4 with trait-based API.

New infrastructure:
- condition_lowering_box.rs: ConditionLoweringBox trait + ConditionContext (293 lines)
- ExprLowerer implements ConditionLoweringBox trait (+51 lines)

Pattern migrations:
- Pattern 2 (loop_with_break_minimal.rs): Use trait API
- Pattern 4 (loop_with_continue_minimal.rs): Use trait API

Benefits:
- Unified condition lowering interface
- Extensible for future lowering strategies
- Clean API boundary between patterns and lowering logic
- Zero code duplication

Test results: 911/911 PASS (+2 new tests)
