44b20bfe28 fix(mir): Complete ScopeContext migration (Phase 2-4 補完) 
Phase 2-4 で移行漏れがあったファイルを修正。

## Changes
- Fixed all remaining compilation errors from incomplete Phase 2-4 migration
- Updated access sites to use scope_ctx.* for 7 legacy fields:
  1. current_function → scope_ctx.current_function
  2. lexical_scope_stack → scope_ctx.lexical_scope_stack
  3. if_merge_stack → scope_ctx.if_merge_stack
  4. debug_scope_stack → scope_ctx.debug_scope_stack
- Updated visibility of ScopeContext to pub(in crate::mir) for cross-module access
- Removed dual-write legacy code in lexical_scope.rs, builder.rs
- Updated documentation comments in phi_helpers.rs

## Files Modified (20 files)
Core access migration:

18d56d5b88 refactor(joinir): Box-First cleanup - trace unification + SSOT + Fail-Fast 
## Changes

### 1. eprintln! to trace.rs unification
**File**: src/mir/builder/control_flow/joinir/routing.rs
- Replaced direct eprintln! with trace::trace().routing()
- Box-First principle: Log responsibility centralized in trace.rs
- Enables filtering via HAKO_JOINIR_DEBUG=1

### 2. Priority field removal (SSOT)
**File**: src/mir/builder/control_flow/joinir/patterns/router.rs
- Removed #[allow(dead_code)] priority field
- Array order is SSOT (Single Source of Truth) for pattern priority
- Pattern try order: Pattern5 → Pattern4 → Pattern3 → Pattern1 → Pattern2
- Eliminated dead code warning

### 3. catch_unwind removal (Fail-Fast)
**File**: src/mir/builder/control_flow/joinir/routing_legacy_binding.rs
- Removed catch_unwind + Ok(None) silent error swallowing
- Fail-Fast principle: Panics propagate explicitly
- Enables early detection of panic sources

## Verification

✅ Build: cargo build --release (0 errors)
✅ Tests: 71 JoinIR tests all PASS
✅ VM: /tmp/p1_return_i.hako → Result: 3
✅ LLVM: /tmp/p1_return_i.hako → Mock exit code: 0

## Design Principles Applied

- **Box-First**: Log responsibility → trace.rs
- **SSOT**: Array order defines priority (no redundant field)
- **Fail-Fast**: Explicit failures, no silent error swallowing

## Statistics

- 3 files changed
- 53 deletions, 28 insertions
- Net: -25 lines (code reduction)

95f3aa429e refactor(joinir): Extract legacy binding path to routing_legacy_binding.rs 
Phase 179-A Step 2: Separate LoopFrontendBinding JSON construction logic
into dedicated module for better organization.

Changes:
- New file: routing_legacy_binding.rs (223 lines)
- routing.rs: cf_loop_joinir_impl() simplified to 15 lines (delegates to legacy path)
- Routing now clearly separates pattern-based vs. legacy binding paths

Benefits:
- Clear separation of concerns (pattern router vs. legacy whitelist)
- routing.rs reduced from 364 to 146 lines (60% reduction)
- Legacy path isolated for future deprecation

24aa8ced75 feat(joinir): Phase 175 - P5 multi-carrier architecture validation 
Task 175-1: Analyzed _parse_string carrier candidates
- Identified 3 carriers: pos (position), result (buffer), is_ch_match (promoted)
- Categorized as: required carriers (pos, result), promoted carrier (is_ch_match)

Task 175-2: Validated existing boxes support multi-carrier
- CarrierInfo: Vec<CarrierData> supports arbitrary carriers ✅
- LoopUpdateAnalyzer: Loops over all carriers ✅
- ExitMeta: Vec<(String, ValueId)> supports all exit bindings ✅
- ExitLineReconnector: Reconnects all carriers to variable_map ✅
- No code changes needed - architecture already supports it!

Task 175-3: PoC test revealed Pattern2 limitation
- Test: test_jsonparser_parse_string_min2.hako (pos + result carriers)
- CarrierInfo detected 3 carriers correctly (pos, result, is_ch_match)
- variable_map contains all carriers at pattern2_start
- BUT: Pattern2's Trim optimization only emits pos carrier in MIR
- MIR shows result stays as empty string (no loop update emitted)
- Root cause: Trim pattern focuses on position-only optimization

Task 175-4: Documentation updates
- Created: phase175-multicarrier-design.md (comprehensive analysis)
- Updated: CURRENT_TASK.md (Phase 175 completion)
- Updated: routing.rs (added JsonParserStringTest2 whitelist)

Key Finding:
- Architecture is sound ✅ - all boxes support multi-carrier
- Pattern2 implementation gap ❌ - Trim optimization ignores non-position carriers
- Phase 176 scope: Extend Pattern2 to emit all carrier updates

Next: Phase 176 for escape sequence handling and full multi-carrier emission

309d0803c7 feat(joinir): Phase 174 - JsonParser complex loop P5 extension design 
- Task 174-1: Complex loop inventory (_parse_string/_parse_array/_parse_object)
  - Analyzed remaining JsonParser loops for P5 expansion potential
  - Identified _parse_string as most Trim-like structure (99% similarity)
  - Documented complexity scores and minimization potential

- Task 174-2: Selected _parse_string as next P5 target (closest to Trim)
  - Reason: LoopBodyLocal 'ch' usage matches Trim pattern exactly
  - Structure: loop(pos < len) + substring + char comparison + break
  - Minimization: Remove escape/buffer/continue → identical to Trim

- Task 174-3: Design doc for P5B extension (TrimLoopHelper reuse strategy)
  - File: docs/development/current/main/phase174-jsonparser-p5b-design.md
  - Strategy: Reuse existing TrimLoopHelper without modifications
  - Proven: Pattern applies to any character comparison, not just whitespace

- Task 174-4: Minimal PoC (_parse_string without escape) successful
  - Test: local_tests/test_jsonparser_parse_string_min.hako
  - Result: [pattern2/trim] Safe Trim pattern detected ✅
  - Detection: Trim with literals=['"'] (quote instead of whitespace)
  - Routing: Added whitelist entries for JsonParserStringTest methods

- Task 174-5: Documentation updates
  - Updated CURRENT_TASK.md with Phase 174 summary
  - Updated joinir-architecture-overview.md with P5 generality proof
  - Created phase174-jsonparser-loop-inventory-2.md (detailed analysis)
  - Created phase174-jsonparser-p5b-design.md (implementation strategy)

Success Criteria Met:
✅ _parse_string minimized version runs on P5 pipeline
✅ TrimLoopHelper works with '"' (non-whitespace character)
✅ Proven: Trim pattern is character-comparison-generic, not whitespace-specific
✅ Two new design docs (inventory + design)
✅ Phase 175+ roadmap established (multi-carrier, escape sequences)

Technical Achievement:
The P5 Trim pipeline successfully handled a quote-detection loop with zero code changes,
proving the architecture's generality beyond whitespace trimming.

290e97c54c feat(joinir): Phase 173 - JsonParser P5 expansion with _skip_whitespace 
- Task 173-1: JsonParser loop inventory recheck
  - Observed 6 loops: _trim (2 loops, already working), _skip_whitespace,
    _parse_string, _parse_array, _unescape_string
  - Created comprehensive observation report with Trim similarity ratings
  - Discovered that JsonParser._trim already uses P5 pipeline successfully

- Task 173-2: Selected _skip_whitespace as Trim-equivalent pattern
  - Perfect structural match with Trim (100% identical)
  - Independent helper method, easy to test
  - Frequently used in JsonParser (7 call sites)

- Task 173-3: Design doc for P5 pipeline extension to JsonParser
  - Confirmed existing TrimLoopHelper works without modification
  - No charAt() support needed (_skip_whitespace uses substring())
  - Documented data flow and risk analysis

- Task 173-4: Successfully converted _skip_whitespace to JoinIR
  - Created test case: local_tests/test_jsonparser_skip_whitespace.hako
  - Added routing whitelist: JsonParserTest._skip_whitespace/3
  - Pattern detection SUCCESS:
    * LoopBodyLocal 'ch' detected
    * Carrier promotion to 'is_ch_match'
    * Trim pattern recognized
    * JoinIR generation successful
  - Verified P5 pipeline works for both static box methods and helper methods

- Task 173-5: Documentation updates
  - phase173-jsonparser-loop-recheck.md: Loop observation report
  - phase173-jsonparser-p5-design.md: P5 extension design
  - phase173-jsonparser-p5-impl.md: Implementation results
  - CURRENT_TASK.md: Phase 173 completion record

Key achievement: Proven that Trim P5 pipeline is fully generic -
works for both TrimTest (static box method) and JsonParser (helper method).
LoopBodyLocal carrier promotion is production-ready for Trim-like patterns.

Changes:
- src/mir/builder/control_flow/joinir/routing.rs: Add JsonParserTest whitelist
- docs/development/current/main/*173*.md: 3 new documentation files
- CURRENT_TASK.md: Phase 173 completion entry

7a9ebf7fc1 feat(joinir): Phase 170-4 Structure-based routing opt-in 
Add NYASH_JOINIR_STRUCTURE_ONLY=1 environment variable to bypass
function name whitelist and route purely based on loop structure.

When enabled:
- Skips hardcoded function name whitelist (13 entries)
- Routes directly to pattern detection (LoopPatternContext)
- Falls back to legacy LoopBuilder if no pattern matches

This is Phase 1 of structure-based routing migration:
- Phase 1: Opt-in via env flag (this commit) ✅
- Phase 2: Make structure-based default (future)
- Phase 3: Remove whitelist entirely (future)

Verified:
- test_loop_return.hako → RC: 2 ✅
- test_trim_loop.hako → RC: 3 ✅

7470bebb0b fix(joinir): Phase 170-B Break condition delegation to condition_to_joinir 
Remove hardcoded break condition (i >= 2) from loop_with_break_minimal.rs.
Now delegates to condition_to_joinir for dynamic break condition lowering.

Changes:
- Add extract_break_condition() to ast_feature_extractor.rs
- Pattern2 lowerer extracts break condition AST and passes to lowerer
- loop_with_break_minimal.rs uses BoolExprLowerer instead of hardcoded values
- Add TrimTest.main/0 to JoinIR routing whitelist

Box Theory compliance:
- Single responsibility: Pattern2 handles structure, condition_to_joinir handles lowering
- Zero hardcoding: All break conditions now dynamic

Verified:
- test_loop_return.hako (i >= 2) → RC: 2 ✅
- test_trim_loop.hako (i >= 3) → RC: 3 ✅

a09ce0cbff feat(joinir): Phase 33-14 JoinFragmentMeta for expr/carrier separation 
Introduces JoinFragmentMeta to distinguish between loop expression results
and carrier variable updates, fixing SSA correctness issues.

## Changes

### New: JoinFragmentMeta struct (carrier_info.rs)
- `expr_result: Option<ValueId>` - Loop as expression (return loop(...))
- `exit_meta: ExitMeta` - Carrier updates for variable_map
- Helper methods: with_expr_result(), carrier_only(), empty()

### Pattern 2 Lowerer Updates
- loop_with_break_minimal.rs: Returns (JoinModule, JoinFragmentMeta)
- pattern2_with_break.rs: Sets boundary.expr_result from fragment_meta

### instruction_rewriter.rs
- Phase 33-14: Only add to exit_phi_inputs when boundary.expr_result is Some
- Phase 33-13: MergeResult struct with carrier_inputs map

### JoinInlineBoundary (inline_boundary.rs)
- New field: expr_result: Option<ValueId>
- All constructors updated with expr_result: None default

## Design Philosophy

Previously, exit_phi_inputs mixed expr results with carrier updates, causing:
- PHI inputs referencing undefined remapped values
- SSA-undef errors in VM execution

With JoinFragmentMeta:
- expr_result → exit_phi_inputs (generates PHI for expr value)
- exit_meta → carrier_inputs (updates variable_map via carrier PHIs)

## Test Results
- Pattern 1 (carrier-only): Works correctly (no exit_phi_inputs)
- Pattern 2 (expr result): Design complete, SSA-undef fix deferred to Phase 33-15

e30116f53d feat(joinir): Phase 171-fix ConditionEnv/ConditionBinding architecture 
Proper HOST↔JoinIR ValueId separation for condition variables:

- Add ConditionEnv struct (name → JoinIR-local ValueId mapping)
- Add ConditionBinding struct (HOST/JoinIR ValueId pairs)
- Modify condition_to_joinir to use ConditionEnv instead of builder.variable_map
- Update Pattern2 lowerer to build ConditionEnv and ConditionBindings
- Extend JoinInlineBoundary with condition_bindings field
- Update BoundaryInjector to inject Copy instructions for condition variables

This fixes the undefined ValueId errors where HOST ValueIds were being
used directly in JoinIR instructions. Programs now execute (RC: 0),
though loop variable exit values still need Phase 172 work.

Key invariants established:
1. JoinIR uses ONLY JoinIR-local ValueIds
2. HOST↔JoinIR bridging is ONLY through JoinInlineBoundary
3. condition_to_joinir NEVER accesses builder.variable_map

abfe0b198b feat(joinir): Phase 195 - Unified JoinLoopTrace for all JoinIR debug output 
Created centralized tracing module for JoinIR loop lowering operations,
consolidating scattered eprintln! calls into a single SSOT interface.

# Implementation

1. **Created trace.rs module** (~233 lines)
   - JoinLoopTrace struct with env var controls
   - Unified API: pattern(), varmap(), joinir_stats(), phi(), merge(), etc.
   - Global singleton via trace() function
   - Supports 5 env vars: NYASH_TRACE_VARMAP, NYASH_JOINIR_DEBUG,
     NYASH_OPTION_C_DEBUG, NYASH_JOINIR_MAINLINE_DEBUG, NYASH_LOOPFORM_DEBUG

2. **Updated debug.rs** - Delegates trace_varmap() to JoinLoopTrace

3. **Updated routing.rs** - All eprintln! replaced with trace calls (10 instances)

4. **Updated pattern routers** - All 3 patterns now use unified trace
   - pattern1_minimal.rs: 6 replacements
   - pattern2_with_break.rs: 6 replacements
   - pattern3_with_if_phi.rs: 6 replacements
   - router.rs: 2 replacements

5. **Updated merge/block_allocator.rs** - 6 eprintln! → trace calls

# Benefits

- **Single Source of Truth**: All trace control through environment variables
- **Consistent Format**: Unified [trace:*] prefix for easy filtering
- **Zero Overhead**: No output when env vars unset
- **Easy Extension**: Add new trace points via existing API
- **Better Debug Experience**: Structured output with clear categories

# Testing

✅ cargo build --release - Success
✅ NYASH_TRACE_VARMAP=1 - Shows varmap traces only
✅ NYASH_JOINIR_DEBUG=1 - Shows joinir + blocks + routing traces
✅ No env vars - No debug output
✅ apps/tests/loop_min_while.hako - All tests pass

# Related

- Phase 191-194 groundwork (modular merge structure)
- NYASH_TRACE_VARMAP added today for variable_map debugging
- Consolidates ~80 scattered eprintln! calls across JoinIR

67e2bfada4 feat(joinir): Phase 194 - Table-driven loop pattern router 
Replace if/else chain with table-driven pattern dispatch for easier
pattern addition and maintenance.

# Changes

## New Files
- router.rs (137 lines): Pattern router table and dispatch logic
  - LoopPatternContext: Context passed to detect/lower functions
  - LoopPatternEntry: Pattern registration structure
  - LOOP_PATTERNS: Static table with 3 registered patterns
  - route_loop_pattern(): Single dispatch function

## Modified Files
- patterns/mod.rs (+8 lines): Export router module
- pattern1_minimal.rs (+19 lines): Added can_lower() + lower() wrapper
- pattern2_with_break.rs (+17 lines): Added can_lower() + lower() wrapper
- pattern3_with_if_phi.rs (+22 lines): Added can_lower() + lower() wrapper
- routing.rs (-21 lines): Replaced if/else chain with router call

# Architecture Improvement

## Before (if/else chain)
```rust
if func_name == "main" && has_sum {
    return pattern3(...);
} else if func_name == "main" {
    return pattern1(...);
} else if func_name == "JoinIrMin.main/0" {
    return pattern2(...);
}
```

## After (table-driven)
```rust
let ctx = LoopPatternContext::new(...);
route_loop_pattern(self, &ctx)?
```

# Adding New Patterns (Now Trivial!)

1. Create pattern4_your_name.rs
2. Implement can_lower() + lower()
3. Add entry to LOOP_PATTERNS table

That's it! No routing logic changes needed.

# Testing

✅ Pattern 1 (loop_min_while.hako): PASSED
✅ Pattern 2 (joinir_min_loop.hako): PASSED
✅ Pattern 3 (loop_if_phi.hako): Routes correctly (VM error is pre-existing)

Router logging verified:
```
NYASH_TRACE_VARMAP=1 ./target/release/hakorune apps/tests/*.hako
[route] Pattern 'Pattern1_Minimal' matched for function 'main'
[route] Pattern 'Pattern2_WithBreak' matched for function 'JoinIrMin.main/0'
[route] Pattern 'Pattern3_WithIfPhi' matched for function 'main'
```

# Line Counts

- router.rs: 137 lines (new)
- Total pattern files: 491 lines (3 patterns)
- routing.rs: Reduced by 21 lines (-6%)
- Net addition: +137 lines (infrastructure investment)

# Documentation

See router.rs header for:
- Architecture overview
- How to add new patterns
- Priority ordering (Pattern3=30, Pattern1=10, Pattern2=20)

Phase 194 complete - pattern addition is now a trivial task!
