ed8e2d3142 feat(joinir): Phase 248 - Normalized JoinIR infrastructure 
Major refactoring of JoinIR normalization pipeline:

Key changes:
- Structured→Normalized→MIR(direct) pipeline established
- ShapeGuard enhanced with Pattern2 loop validation
- dev_env.rs: New development fixtures and env control
- fixtures.rs: jsonparser_parse_number_real fixture
- normalized_bridge/direct.rs: Direct MIR generation from Normalized
- pattern2_step_schedule.rs: Extracted step scheduling logic

Files changed:
- normalized.rs: Enhanced NormalizedJoinModule with DevEnv support
- shape_guard.rs: Pattern2-specific validation (+300 lines)
- normalized_bridge.rs: Unified bridge with direct path
- loop_with_break_minimal.rs: Integrated step scheduling
- Deleted: step_schedule.rs (moved to pattern2_step_schedule.rs)

New files:
- param_guess.rs: Loop parameter inference
- pattern2_step_schedule.rs: Step scheduling for Pattern2
- phase43-norm-canon-p2-mid.md: Design doc

Tests: 937/937 PASS (+6 from baseline 931)

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)

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
