feat(joinir): Phase 282 P3 - Pattern1 ExtractionBased Migration
...
Migrated Pattern1 (Simple While Loop) from StructureBased to ExtractionBased
detection, creating a migration template for Pattern2-5.
**Changes**:
1. Created extractors/mod.rs - Module entry point with design principles
2. Created extractors/pattern1.rs - Pure extraction functions with 4-phase validation
3. Updated pattern1_minimal.rs - can_lower() + lower() use extraction
4. Updated mod.rs - Registered extractors module
**Pattern1Parts Design** (Lightweight):
- Stores only loop_var (AST reused from ctx, no heavy copies)
- Validation: 比較条件 + no break/continue/if-else + 単純step (i = i ± const)
- Return statements allowed (not loop control flow)
**4-Phase Validation**:
1. Validate condition structure (比較演算, left=variable)
2. Validate body (no break/continue/if-else-phi)
3. Validate step pattern (simple i = i ± const only)
4. Extract loop variable
**Safety Valve Strategy**:
- pattern_kind as O(1) early rejection guard
- Extraction as SSOT authoritative check
- Re-extraction in lower() (no caching from can_lower)
**Testing**:
- Unit tests: 3/3 PASS
- Build: 0 errors
- Regression: 45/46 PASS (zero regression)
**Migration Template**:
- Result<Option<Parts>, String> return type (Pattern8/9 model)
- Pure functions (no builder mutations)
- Fail-Fast error handling (Err for logic bugs, Ok(None) for non-matches)

refactor(pattern2): move promotion decision into pattern2/api SSOT
...
Phase 263 P0.2: pattern2/api/ フォルダ化 - 入口SSOTの物理固定
目的: PromoteDecision/try_promote の参照点を1箇所に閉じ込めて、迷子防止
Changes:
1. 新規フォルダ構造:
- pattern2/api/mod.rs - 入口SSOT（try_promote と PromoteDecision を再export）
- pattern2/api/promote_decision.rs - PromoteDecision/PromoteStepResult 型定義
- pattern2/api/promote_runner.rs - try_promote(...) 実装（SSOT entry point）
- pattern2/mod.rs - api モジュールを公開
2. 移動/抽出:
- PromoteDecision enum を promote_step_box.rs → pattern2/api/promote_decision.rs へ
- promote_and_prepare_carriers を try_promote として pattern2/api/promote_runner.rs へ抽出
3. promote_step_box.rs を薄いラッパに縮退（35行, -177行）:
- pattern2::api::try_promote を呼び出すだけの互換用ラッパ
- 将来的に削除予定（deprecated）
4. orchestrator を新API に書き換え:
- use super::pattern2::api::{try_promote, PromoteDecision};
- try_promote(...) を直接呼び出し
5. 参照確認:
- rg で確認: すべての参照が pattern2::api 経由に収束 ✅
検証:
- cargo test --lib: 1368/1368 PASS ✅
- quick smoke: 45/46 PASS ✅ （悪化なし）
- 参照点が pattern2/api に一本化され、迷子防止を物理的に保証

feat(joinir): Phase 259 P0 - Pattern8 BoolPredicateScan + Copy binding fix
...
Pattern8 (Boolean Predicate Scan) implementation for is_integer/1:
- New pattern detection for `loop + if not predicate() { return false }`
- JoinIR lowerer with main/loop_step/k_exit structure
- Me receiver passed as param (by-name 禁止)
Key fixes:
1. expr_result = Some(join_exit_value) (Pattern7 style)
2. Tail-call: dst: None (no extra Ret instruction)
3. instruction_rewriter: Add `&& is_loop_header_with_phi` check
- Pattern8 has no carriers → no PHIs → MUST generate Copy bindings
- Without this, ValueId(103/104/105) were undefined
Status: Copy instructions now generated correctly, but exit block
creation issue remains (next step: Step A-C in指示書).

fix(joinir): Phase 256 P1 - Carrier PHI wiring and parameter mapping (in progress)
...
**Status**: Core carrier PHI issue partially resolved, debugging loop body
**Progress**:
✅ Task 1: split_scan_minimal.rs Carriers-First ordering (6 locations)
✅ Task 2: pattern7_split_scan.rs boundary configuration (host/join inputs, exit_bindings, expr_result)
✅ Result now flows from k_exit to post-loop code (RC issue resolved)
⚠️ Loop body instruction execution needs review
**Key Fixes**:
1. Fixed host_inputs/join_inputs to match main() params Carriers-First order
2. Added result to exit_bindings (CarrierRole::LoopState)
3. Added result back to loop_invariants for variable initialization
4. Added expr_result=join_exit_value_result for loop expression return
5. Fixed jump args to k_exit to include all 4 params [i, start, result, s]
**Current Issue**:
- Loop body type errors resolved (String vs Integer fixed)
- New issue: Loop body computations (sep_len) undefined in certain blocks
- Likely cause: JoinIR→MIR conversion of local variables needs review
**Next Steps**:
- Review JoinValueSpace allocation and ValueId mapping in conversion
- Verify loop_step instruction ordering and block structure
- May need to refactor bound computation or revisit split algorithm

refactor(joinir): Phase 255 P2 - loop_invariants + var() unification + Phase 256 prep
...
## Task A: Loop Invariants Architecture (Option A - Boundary Extension)
Introduced explicit loop_invariants concept for variables that are:
- Used in loop body but never modified (e.g., substring needle in index_of)
- Need header PHI (all iterations use same value)
- Do NOT need exit PHI (not a LoopState)
Implementation:
- Added `loop_invariants: Vec<(String, ValueId)>` field to JoinInlineBoundary
- Added `with_loop_invariants()` method to JoinInlineBoundaryBuilder
- Modified Pattern 6 to use loop_invariants instead of ConditionOnly misuse
* s (haystack) and ch (needle) now properly classified
* exit_bindings simplified to only LoopState carriers
- Extended LoopHeaderPhiBuilder to generate invariant PHIs
* Entry PHI: from host
* Latch PHI: self-reference (same value every iteration)
- Updated instruction_rewriter to handle invariant latch incoming
Files Modified:
- src/mir/join_ir/lowering/inline_boundary.rs (structure + builder)
- src/mir/join_ir/lowering/inline_boundary_builder.rs (builder method)
- src/mir/builder/control_flow/joinir/patterns/pattern6_scan_with_init.rs
- src/mir/builder/control_flow/joinir/merge/loop_header_phi_builder.rs
- src/mir/builder/control_flow/joinir/merge/mod.rs
- src/mir/builder/control_flow/joinir/merge/instruction_rewriter.rs
## Task B: Code Quality - var() Helper Unification
Created common module to eliminate var() duplication:
- New module: src/mir/builder/control_flow/joinir/patterns/common/
- Centralized var() helper in ast_helpers.rs
- Updated Pattern 6 and Pattern 2 to use common var()
- Test code (5 occurrences) deferred to Phase 256+ per 80/20 rule
Result: Eliminated 2 duplicate var() functions, 5 test occurrences remain
Files Created:
- src/mir/builder/control_flow/joinir/patterns/common/ast_helpers.rs
- src/mir/builder/control_flow/joinir/patterns/common/mod.rs
Files Modified:
- src/mir/builder/control_flow/joinir/patterns/mod.rs
- src/mir/builder/control_flow/joinir/patterns/pattern6_scan_with_init.rs
- src/mir/builder/control_flow/joinir/patterns/policies/balanced_depth_scan_policy.rs
## Task C: Documentation - PostLoopEarlyReturnPlan Usage Examples
Enhanced post_loop_early_return_plan.rs with:
- Architecture explanation (exit PHI usage prevents DCE)
- Pattern 2 example (Less: balanced_depth_scan)
- Pattern 6 example (NotEqual: index_of)
- Builder defer decision: when 4+ patterns emerge, add builder
Files Modified:
- src/mir/builder/control_flow/joinir/patterns/policies/post_loop_early_return_plan.rs
## Task D: Phase 256 Preparation
Analyzed next failure from smoke tests:
- `StringUtils.split/2` with variable-step loop
- Not constant step (i += len or similar)
- Three implementation options identified
Created Phase 256 README with:
- Minimal reproduction code
- Root cause analysis
- Implementation options with trade-offs
- Clear next steps
Files Created:
- docs/development/current/main/phases/phase-256/README.md
## Verification Results
✅ All tests passing:
- pattern254_p0_index_of_vm.sh: PASS
- No regression in Pattern 1-5
- Smoke test progresses past json_lint_vm to next failure
✅ Architecture achievements:
- Semantic clarity: loop_invariants vs exit_bindings properly separated
- ConditionOnly misuse eliminated
- PHI generation correct for all carrier types
- Code quality: var() duplication reduced
- Next phase clearly defined
## Summary
Phase 255 P2 achieves root-cause fix for multi-param loop support:
- Boundary concept expanded (loop_invariants field)
- Pattern 6 architecture corrected (no ConditionOnly misuse)
- Code quality improved (var() centralized)
- Next pattern (variable-step) is now the challenge
✨ Box-first principles maintained: clean separation, explicit roles, minimal coupling

feat(joinir): Phase 254-255 - Pattern 6 (ScanWithInit) + exit PHI DCE fix
...
## Phase 254: Pattern 6 (ScanWithInit) Detection & JoinIR Lowering
Pattern 6 detects index_of/find/contains-style loops:
- Loop condition: i < x.length()
- Loop body: if with method call condition + early return
- Step: i = i + 1
- Post-loop: return not-found value (-1)
Key features:
- Minimal lowering: main/loop_step/k_exit functions
- substring hoisted to init-time BoxCall
- Two k_exit jumps (found: i, not found: -1)
- Tests: phase254_p0_index_of_min.hako
## Phase 255 P0: Multi-param Loop CarrierInfo
Implemented CarrierInfo architecture for Pattern 6's 3-variable loop (s, ch, i):
- i: LoopState (header PHI + exit PHI)
- s, ch: ConditionOnly (header PHI only)
- Alphabetical ordering for determinism
- All 3 PHI nodes created correctly
- Eliminates "undefined ValueId" errors
## Phase 255 P1: Exit PHI DCE Fix
Prevents exit PHI from being deleted by DCE:
- PostLoopEarlyReturnStepBox emits post-loop guard
- if (i != -1) { return i } forces exit PHI usage
- Proven pattern from Pattern 2 (balanced_depth_scan)
- VM/LLVM backends working
## Test Results
✅ pattern254_p0_index_of_vm.sh: PASS (exit code 1)
✅ pattern254_p0_index_of_llvm_exe.sh: PASS (mock)
✅ Quick profile: json_lint_vm PASS (progresses past index_of)
✅ Pattern 1-5: No regressions

if let Some(value_id) = env.get(name) { return Ok(value_id); }
// Priority 2: LoopBodyLocalEnv (body-local like `ch`)
if let Some(body_env) = body_local_env {
if let Some(value_id) = body_env.get(name) { return Ok(value_id); }
}
```

refactor(phase-91): Modularize P5b escape pattern recognizer
...
### Changes
#### 1. New Module: escape_pattern_recognizer.rs (255 lines)
- Dedicated module for P5b (Escape Sequence Handling) pattern
- Single Responsibility Principle: handles only escape pattern detection
- Clean interface: exports only `detect_escape_skip_pattern()` and `EscapeSkipPatternInfo`
- Private helpers for pattern-specific analysis
**Moved functions**:
- `detect_escape_skip_pattern()` - main recognizer
- `find_break_in_if()` - break detection
- `find_escape_in_if()` - escape check detection
- `extract_delta_pair_from_if()` - delta extraction
- `try_extract_increment_assignment()` - increment parsing
#### 2. ast_feature_extractor.rs (1046 lines, was 1345)
- Removed deprecated `extract_escape_delta_from_if()` function
- Removed P5b-specific implementation (moved to escape_pattern_recognizer)
- Added re-export for backward compatibility
- **Result**: 299 lines removed (77% of original), cleaner focus on general pattern analysis
#### 3. mod.rs (patterns/)
- Registered new `escape_pattern_recognizer` module
- Updated documentation to reflect modularization
### Results
✅ **File Size Reduction**: 1345 → 1046 lines in ast_feature_extractor
✅ **Code Organization**: Single-responsibility modules
✅ **Reusability**: P5b helpers isolated for Phase 92+ reuse
✅ **Test Status**: 1062/1062 tests PASS (no regressions)
✅ **Dead Code**: Removed deprecated function
### Architecture Improvement
**Before**:
```
ast_feature_extractor.rs (1345 lines)
├─ Generic pattern detection (detect_continue, detect_parse_*, etc.)
└─ P5b-specific helpers (deeply nested, hard to navigate)
```
**After**:
```
ast_feature_extractor.rs (1046 lines) - Generic patterns only
escape_pattern_recognizer.rs (255 lines) - P5b-specific, organized
├─ Main recognizer
└─ Focused private helpers
```
### Next Steps
- Phase 92: Implement JoinIR lowering for P5b using this recognizer
- Phase 93: Pattern P5 (guard-bounded) detection
Boxification/modularity complete! 🎉

feat(mir): Phase 143 P1 - Add parse_string pattern to canonicalizer
...
Expand loop canonicalizer to recognize parse_string patterns with both
continue (escape handling) and return (quote found) statements.
## Implementation
### New Pattern Detection (ast_feature_extractor.rs)
- Add `detect_parse_string_pattern()` function
- Support nested continue detection using `has_continue_node()` helper
- Recognize both return and continue in same loop body
- Return ParseStringInfo { carrier_name, delta, body_stmts }
- ~120 lines added
### Canonicalizer Integration (canonicalizer.rs)
- Try parse_string pattern first (most specific)
- Build LoopSkeleton with HeaderCond, Body, Update steps
- Set ExitContract: has_continue=true, has_return=true
- Route to Pattern4Continue (both exits present)
- ~45 lines modified
### Export Chain
- Add re-exports through 7 module levels:
ast_feature_extractor → patterns → joinir → control_flow → builder → mir
- 10 lines total across 7 files
### Unit Test
- Add `test_parse_string_pattern_recognized()` in canonicalizer.rs
- Verify skeleton structure (3+ steps)
- Verify carrier (name="p", delta=1, role=Counter)
- Verify exit contract (continue=true, return=true, break=false)
- Verify routing decision (Pattern4Continue, no missing_caps)
- ~180 lines added
## Target Pattern
`tools/selfhost/test_pattern4_parse_string.hako`
Pattern structure:
- Check for closing quote → return
- Check for escape sequence → continue (nested inside another if)
- Regular character processing → p++
## Results
- ✅ Strict parity green: Pattern4Continue
- ✅ All 19 unit tests pass
- ✅ Nested continue detection working
- ✅ ExitContract correctly set (first pattern with both continue+return)
- ✅ Default behavior unchanged
## Technical Challenges
1. Nested continue detection required recursive search
2. First pattern with both has_continue=true AND has_return=true
3. Variable step updates (p++ vs p+=2) handled with base delta
## Statistics
- New patterns: 1 (parse_string)
- Total patterns: 4 (skip_whitespace, parse_number, continue, parse_string)
- New capabilities: 0 (uses existing ConstStep)
- Lines added: ~300
- Files modified: 9
- Parity status: Green ✅

feat(canonicalizer): Phase 143-P0 - parse_number pattern support
...
Add parse_number pattern recognition to canonicalizer, expanding adaptation
range for digit collection loops with break in THEN clause.
## Changes
### New Recognizer (ast_feature_extractor.rs)
- `detect_parse_number_pattern()`: Detects `if invalid { break }` pattern
- `ParseNumberInfo`: Struct for extracted pattern info
- ~150 lines added
### Canonicalizer Integration (canonicalizer.rs)
- Parse_number pattern detection before skip_whitespace
- LoopSkeleton construction with 4 steps (Header + Body x2 + Update)
- Routes to Pattern2Break (has_break=true)
- ~60 lines modified
### Export Chain (6 files)
- patterns/mod.rs → joinir/mod.rs → control_flow/mod.rs
- builder.rs → mir/mod.rs
- 8 lines total
### Tests
- `test_parse_number_pattern_recognized()`: Unit test for recognition
- Strict parity verification: GREEN (canonical and router agree)
- ~130 lines added
## Pattern Comparison
| Aspect | Skip Whitespace | Parse Number |
|--------|----------------|--------------|
| Break location | ELSE clause | THEN clause |
| Pattern | `if cond { update } else { break }` | `if invalid { break } rest... update` |
| Body after if | None | Required (result append) |
## Results
- ✅ Skeleton creation successful
- ✅ RoutingDecision matches router (Pattern2Break)
- ✅ Strict parity OK (canonicalizer ↔ router agreement)
- ✅ Unit test PASS
- ✅ Manual test: test_pattern2_parse_number.hako executes correctly
## Statistics
- New patterns: 1 (parse_number)
- Total patterns: 3 (skip_whitespace, parse_number, continue)
- Lines added: ~280
- Files modified: 8
- Parity status: Green ✅

- Pattern 4 を狭化: has_continue && !has_break のみ
- 誤ルーティング完全除去
## Step C: Pattern Module
- pattern5_infinite_early_exit.rs 新規作成
- Fail-Fast 設計: 超狭い shape guard
- lowering はスケルトン（Phase 131-11-D で実装）
## 動作確認
- Pattern 5 正常検出 ✅
- Shape guards 動作（1 break, 1 continue, 1 carrier）✅
- Pattern 4 誤ルーティング回避 ✅

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!
