2c68b04e49 feat(joinir): Phase 188 Pattern 1 tail call parameter binding 
Problem: Tail call conversion (Call→Jump) was failing because:
1. Function parameters were not bound, causing "undefined value" errors
2. Instructions before Call (like BoxCall for print) were being skipped

Solution: Implemented two-pass tail call conversion:
- First pass: Process all instructions, detect tail calls, skip only Call itself
- Second pass: Insert Copy instructions to bind call arguments to parameters

Implementation:
- Lines 517-609: Two-pass approach with tail_call_target tracking
- Lines 588-603: Parameter binding via Copy instructions (arg → param)
- Lines 566-573: Debug logging for BoxCall verification

Example binding:
  Call(loop_step, [i_next])
  → Copy { dst: param_i, src: i_next }
  → Jump(loop_step_entry)

Status: JoinIR firing ✅, parameter binding ✅
Blocker: Non-deterministic HashMap iteration (next fix)

074fab8459 fix(joinir): Phase 189 HashMap collision bug fix - composite keys 
Problem: Multiple JoinIR functions had blocks with identical BasicBlockIds
(e.g., func_0 and func_2 both had BasicBlockId(0)), causing HashMap key
collisions in merge_joinir_mir_blocks(). This corrupted block mappings
and prevented multi-function JoinIR→MIR merge.

Solution: Use composite keys (String, BasicBlockId) instead of simple
BasicBlockId in the global block_map to guarantee uniqueness across
functions.

Implementation:
- Line 399: Changed block_map type to HashMap<(String, BasicBlockId), BasicBlockId>
- Lines 491-507: Added per-function local_block_map for remap compatibility
- Lines 610-616: Updated entry function block_map access to use composite key

Verification:
- Build: ✅ 0 errors (34 unrelated warnings)
- Coverage: ✅ 100% (all 4 block_map accesses use composite keys)
- Performance: ✅ O(1) HashMap lookups maintained

Phase 189 Status: ✅ COMPLETED (1h vs 4-6h estimate)

5bc0fa861f feat(joinir): Phase 188 Pattern 1 Core Implementation + Phase 189 Planning 
Phase 188 Status: Planning & Foundation Complete (100%)

Completed Tasks:
✅ Task 188-1: Error Inventory (5 patterns identified)
✅ Task 188-2: Pattern Classification (3 patterns selected)
✅ Task 188-3: Design (51KB comprehensive blueprint)
✅ Task 188-4: Implementation Foundation (1,802 lines scaffolding)
✅ Task 188-5: Verification & Documentation
✅ Pattern 1 Core Implementation: Detection + Lowering + Routing

Pattern 1 Implementation (322 lines):
- Pattern Detection: is_simple_while_pattern() in loop_pattern_detection.rs
- JoinIR Lowering: lower_simple_while_to_joinir() in simple_while_minimal.rs (219 lines)
  - Generates 3 functions: entry, loop_step (tail-recursive), k_exit
  - Implements condition negation: exit_cond = !(i < 3)
  - Tail-recursive Call pattern with state propagation
- Routing: Added "main" to function routing list in control_flow.rs
- Build: ✅ SUCCESS (0 errors, 34 warnings)

Infrastructure Blocker Identified:
- merge_joinir_mir_blocks() only handles single-function JoinIR modules
- Pattern 1 generates 3 functions (entry + loop_step + k_exit)
- Current implementation only merges first function → loop body never executes
- Root cause: control_flow.rs line ~850 takes only .next() function

Phase 189 Planning Complete:
- Goal: Refactor merge_joinir_mir_blocks() for multi-function support
- Strategy: Sequential Merge (Option A) - merge all functions in call order
- Effort estimate: 5.5-7.5 hours
- Deliverables: README.md (16KB), current-analysis.md (15KB), QUICKSTART.md (5.8KB)

Files Modified/Created:
- src/mir/loop_pattern_detection.rs (+50 lines) - Pattern detection
- src/mir/join_ir/lowering/simple_while_minimal.rs (+219 lines) - Lowering
- src/mir/join_ir/lowering/loop_patterns.rs (+803 lines) - Foundation skeleton
- src/mir/join_ir/lowering/mod.rs (+2 lines) - Module registration
- src/mir/builder/control_flow.rs (+1 line) - Routing fix
- src/mir/builder/loop_frontend_binding.rs (+20 lines) - Binding updates
- tools/test_phase188_foundation.sh (executable) - Foundation verification
- CURRENT_TASK.md (updated) - Phase 188/189 status

Next: Phase 189 implementation (merge_joinir_mir_blocks refactor)

30f94c9550 feat(joinir): Phase 186 LoopBuilder Hard Freeze - Add access control guard 
Add environment variable check at LoopBuilder fallback point (control_flow.rs:60).
LoopBuilder is now only accessible when NYASH_LEGACY_LOOPBUILDER=1 is explicitly set.

Changes:
- control_flow.rs: Add env guard before LoopBuilder instantiation
- Default behavior: JoinIR-only (LoopBuilder disabled)
- Legacy mode: NYASH_LEGACY_LOOPBUILDER=1 enables fallback
- Error message: Clear hint about legacy mode opt-in

Testing:
- legacy OFF (NYASH_LEGACY_LOOPBUILDER=0): Error (frozen)
- legacy ON (NYASH_LEGACY_LOOPBUILDER=1): Success (allowed)

7de192aa6b feat(mir): Phase 69-3 Fix MIR non-determinism with BTreeSet 
Replace HashSet with BTreeSet for CFG predecessors/successors:
- BasicBlock.predecessors: HashSet → BTreeSet
- BasicBlock.successors: HashSet → BTreeSet
- LoopFormOps.get_block_predecessors(): returns BTreeSet
- BasicBlock.dominates(): takes &[BTreeSet<BasicBlockId>]

This ensures deterministic PHI generation and test stability.

Test results:
- loop_with_continue_and_break tests: now deterministic (3/3 same output)
- loopform tests: 14/14 PASS (no regressions)
- merge_exit_with_classification tests: 3/3 PASS

Technical changes (6 files):
- basic_block.rs: BTreeSet types + new() initialization
- loopform_builder.rs: trait signature + 2 mock implementations
- phi_ops.rs: return type
- json_v0_bridge/loop_.rs: return type

Same pattern as Phase 25.1 (MirFunction.blocks HashMap → BTreeMap).

3dc691d39f feat(joinir): Phase 50 Loop Frontend Binding layer 
Phase 50 implements the Loop Frontend Binding layer that maps
actual loop variables to JoinIR Frontend's expected names (i, acc, n).

## Changes

- Add loop_frontend_binding.rs module with:
  - LoopFrontendBinding struct for variable mapping
  - for_print_tokens() and for_array_filter() factory methods
  - generate_local_declarations() for JSON v0 format
  - rename_body_variables() for out → acc renaming

- Integrate binding with cf_loop_joinir_impl:
  - Create binding based on function name
  - Inject i/acc/n Local declarations into JSON v0
  - Use correct JoinIR Frontend type names (Int/Var/Method)

## Limitations Found

JoinIR Frontend doesn't support:
- Field access (me.tokens) - blocks print_tokens
- NewBox (new ArrayBox()) - blocks array_filter

These will be addressed in Phase 51.

f74b7d2b04 📦 Hotfix 1 & 2: Parameter ValueId Reservation + Exit PHI Validation (Box-First Theory) 
**箱理論に基づく根治的修正**：

## 🎯 Hotfix 1: Parameter ValueId Reservation (パラメータ ValueId 予約)

### 根本原因
- MirFunction counter が params.len() を考慮していなかった
- local variables が parameter ValueIds を上書き

### 箱理論的解決
1. **LoopFormContext Box**
   - パラメータ予約を明示的に管理
   - 境界をはっきりさせる

2. **MirFunction::new() 改善**
   - `initial_counter = param_count.max(1)` でパラメータ予約
   - Parameters are %0, %1, ..., %N-1

3. **ensure_counter_after() 強化**
   - パラメータ数 + 既存 ValueIds 両方を考慮
   - `min_counter = param_count.max(max_id + 1)`

4. **reserve_parameter_value_ids() 追加**
   - 明示的な予約メソッド（Box-First）

## 🎯 Hotfix 2: Exit PHI Predecessor Validation (Exit PHI 検証)

### 根本原因
- LoopForm builder が存在しないブロックを PHI predecessor に追加
- 「幽霊ブロック」問題

### 箱理論的解決
1. **LoopFormOps.block_exists() 追加**
   - CFG 存在確認メソッド
   - 境界を明確化

2. **build_exit_phis() 検証**

eadde8d1dd fix(mir/builder): use function-local ValueId throughout MIR builder 
Phase 25.1b: Complete SSA fix - eliminate all global ValueId usage in function contexts.

Root cause: ~75 locations throughout MIR builder were using global value
generator (self.value_gen.next()) instead of function-local allocator
(f.next_value_id()), causing SSA verification failures and runtime
"use of undefined value" errors.

Solution:
- Added next_value_id() helper that automatically chooses correct allocator
- Fixed 19 files with ~75 occurrences of ValueId allocation
- All function-context allocations now use function-local IDs

Files modified:
- src/mir/builder/utils.rs: Added next_value_id() helper, fixed 8 locations
- src/mir/builder/builder_calls.rs: 17 fixes
- src/mir/builder/ops.rs: 8 fixes
- src/mir/builder/stmts.rs: 7 fixes
- src/mir/builder/emission/constant.rs: 6 fixes
- src/mir/builder/rewrite/*.rs: 10 fixes
- + 13 other files

Verification:
- cargo build --release: SUCCESS
- Simple tests with NYASH_VM_VERIFY_MIR=1: Zero undefined errors
- Multi-parameter static methods: All working

Known remaining: ValueId(22) in Stage-B (separate issue to investigate)
