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)
Next: Phase 48-A implementation (when requested)

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.

c3a26e705e feat(joinir): Phase 47-A-IMPL - P3 Normalized infrastructure
Implement Pattern3 (if-sum) Normalized infrastructure, extending existing P2
StepSchedule and ShapeGuard systems.

Key changes:

1. StepSchedule generalization (P2 → P2/P3):
   - Renamed: pattern2_step_schedule.rs → step_schedule.rs
   - Extended StepKind enum with P3 variants:
     - IfCond (if condition in body)
     - ThenUpdates (carrier updates in then branch)
     - ElseUpdates (carrier updates in else branch)
   - Added pattern3_if_sum_schedule() function
   - Added unit test: test_pattern3_if_sum_schedule()
   - Updated module references (mod.rs, loop_with_break_minimal.rs)

2. ShapeGuard extension:
   - Added Pattern3IfSumMinimal variant to NormalizedDevShape
   - Added is_pattern3_if_sum_minimal() detector (placeholder)
   - Updated shape detector table
   - Extended capability_for_shape() mapping

3. Bridge integration:
   - bridge.rs: Added P3 shape handling in normalize_for_shape()
   - normalized.rs: Added P3 roundtrip match (uses P2 temporarily)

4. P2/P3 separation:
   - loop_with_break_minimal.rs: Added panic for P3 steps in P2 lowering
   - Clear boundary enforcement (P2 lowerer rejects P3 steps)

5. Documentation:
   - CURRENT_TASK.md: Phase 47-A-IMPL status
   - phase47-norm-p3-design.md: Implementation status section

Benefits:
- Reuses 90% of P2 infrastructure (ConditionEnv, CarrierInfo, ExitLine)
- Clean P2/P3 separation via StepKind
- Pure additive changes (no P2 behavioral changes)
- Ready for Phase 47-A-LOWERING (full P3 Normalized implementation)

Tests: 938/938 PASS (+1 from step_schedule unit test)
- All existing P1/P2 tests pass (no regressions)
- P3 test uses Structured path temporarily (proper lowering in next phase)

Next phase: Implement full P3 Normalized→MIR(direct) lowering

  - 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")]

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)

ConditionEnv integration), so Normalized extension is straightforward.

Design documents:
- phase47-norm-p3-design.md: Complete P3 Normalized design
  - Infrastructure reuse analysis (ConditionEnv, CarrierInfo, ExitLine)
  - Representative loops identified (phase212_if_sum_min primary target)
  - StepScheduleBox extension (IfCond, ThenUpdates, ElseUpdates)
  - JpInst reuse (If instruction already exists)
  - Implementation strategy (dev-only → canonical)
  - File impact estimate (~365 lines, pure additive)

- phase47-test-files-inventory.md: P3 test file catalog
  - 3 P3 test files analyzed
  - phase212_if_sum_min.hako: Single carrier (PRIMARY)
  - phase217_if_sum_multi_min.hako: Multi-carrier (sum + count)
  - phase218_json_if_sum_min.hako: Variable accumulation (sum + i)

Architecture:
- Unified Normalized for P1/P2/P3 (same pipeline)
- Conditional updates only difference vs P2
- No P2 code changes needed (pure additive)

Benefits:
- 90% infrastructure reuse from P2
- Proven incremental rollout (dev → canonical)
- Clear path to P4 (continue pattern)

Implementation roadmap:
- Phase 47-A: Minimal sum_count (dev-only)
- Phase 47-B: array_filter (body-local + method calls)
- Phase 47-C: Canonical promotion

Updates:
- joinir-architecture-overview.md: Added Phase 47 section
- CURRENT_TASK.md: Updated Phase 47 entry (Design Complete)

Status: Design phase complete, ready for implementation

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

- verification_flags.rs (61 lines, 7 functions) - Verification/SSA flags
- selfhost_flags.rs (98 lines, 12 functions) - Selfhost NY compiler flags

**Improvements**:
- IDE discoverability: `joinir_flags::`, `mir_flags::` in autocomplete
- Single Responsibility: Each Box handles one semantic area
- Maintainability: ~100-200 line modules instead of 948 line monolith
- Scalability: Easy to add new flags to appropriate modules
- Backward compatibility: All functions re-exported at `crate::config::env::`

**Verification**:
- 937/937 tests PASS (zero regressions)
- cargo build --release succeeds
- No code changes required in existing callsites (backward compatible)

Box-First architecture:
- 箱に切り出す: 106 functions → 7 semantic modules
- 境界をはっきりさせる: Each module has clear responsibility
- 差し替え可能: Backward-compatible re-exports
- いつでも戻せる: Original backup created, reverts are safe

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
-  dual-value carrier resolution
-  FromHost carrier handling
- ⚠️ RC:0 issue (runtime value problem, Part 2)

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!) |

- 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)

811dfebf98 fix(joinir): Phase 241-EX - Remove hardcoded 'sum' check from Pattern3
Remove legacy hardcoded 'sum' carrier validation that was blocking
array_filter patterns with different accumulator names (e.g., 'out').

Before: Pattern3 required carrier named 'sum' to exist
After: Pattern3 uses carrier_info generically (any carrier name works)

Test results:
- phase49_joinir_array_filter_smoke: PASS 
- phase49_joinir_array_filter_fallback: PASS 
- phase49_joinir_array_filter_ab_comparison: PASS

89a769198a feat(joinir): Phase 223-3 - LoopBodyCondPromoter implementation
Implements LoopBodyLocal condition promotion for Pattern4/continue patterns.
Previously, loops with LoopBodyLocal in conditions would Fail-Fast.
Now, safe Trim/skip_whitespace patterns (Category A-3) are promoted and lowering continues.

## Implementation

- **LoopBodyCondPromoter Box** (loop_body_cond_promoter.rs)
  - extract_continue_condition(): Extract if-condition from continue branches
  - try_promote_for_condition(): Thin wrapper delegating to LoopBodyCarrierPromoter
  - ConditionPromotionRequest/Result API for Pattern2/4 integration

- **Pattern4 Integration** (pattern4_with_continue.rs)
  - Analyze both header condition + continue condition
  - On promotion success: merge carrier_info → continue lowering
  - On promotion failure: Fail-Fast with clear error message

- **Unit Tests** (5 tests, all PASS)
  - test_cond_promoter_skip_whitespace_pattern
  - test_cond_promoter_break_condition
  - test_cond_promoter_non_substring_pattern
  - test_cond_promoter_no_scope_shape
  - test_cond_promoter_no_body_locals

- **E2E Test** (phase223_p4_skip_whitespace_min.hako)
  - Category A-3 pattern: local ch = s.substring(...); if ch == " " { continue }
  - Verifies promotion succeeds and Pattern4 lowering proceeds

## Documentation

- joinir-architecture-overview.md: Updated LoopBodyCondPromoter section (Phase 223-3 完了)
- CURRENT_TASK.md: Added Phase 223-3 completion summary
- PHASE_223_SUMMARY.md: Phase overview and status tracking
- phase223-loopbodylocal-condition-*.md: Design docs and inventory

## Achievement

- **Before**: LoopBodyLocal in condition → Fail-Fast
- **Now**: Trim/skip_whitespace patterns promoted → Pattern4 lowering continues
- **Remaining**: Phase 172+ JoinIR Trim lowering for complete RC correctness
