refactor(joinir): Phase 286C-2.1 Step 3 - Extract scan logic into scan_blocks()
...
- Move instruction identification logic from main loop to scan_blocks()
- Populate RewritePlan with tail_calls, return_conversions
- Read-only analysis phase complete (no mutations, just detection)
- merge_and_rewrite() now calls scan_blocks() to identify rewrites
Scan logic extracted:
- Tail call detection: Check Call instructions for intra-module calls
- Return detection: Identify Return terminators for exit jump conversion
- Populate TailCallRewrite with target_func_name, target_block, args
- Populate ReturnConversion with return_value, has_exit_edge_args

Benefits:
- Borrow checker safety: Sequential calling pattern (no overlapping borrows)
- Clear extraction targets: TODO markers identify logic to move
- Build stability: Stubs compile successfully, no functionality changes yet
- Foundation for incremental refactoring: Steps 2-5 can now proceed safely
Strategic Markers:
- Line 205: STAGE 1 marker (scan logic)
- Line 282: STAGE 2 marker (plan logic)
- Line 1355: STAGE 3 marker (apply logic)
- Line 1514: Future orchestrator structure
Status:
- Scaffolding: ✅ Complete (stubs in place)

refactor(phase284): P1 SSOT Consolidation - Block Remapper & Return Emitter
...
## Summary
Refactored Phase 284 P1 codebase to consolidate scattered logic into SSOT
(Single Source of Truth) modules, improving maintainability and enabling
Pattern4/5 code reuse.
## New Modules
### 1. Block Remapper SSOT
**File**: `src/mir/builder/control_flow/joinir/merge/block_remapper.rs` (152 lines)
- **Purpose**: Consolidate block ID remapping logic (Phase 284 P1 fix)
- **Function**: `remap_block_id(block_id, local_block_map, skipped_entry_redirects)`
- **Rule**: local_block_map priority > skipped_entry_redirects (prevents ID collision)
- **Tests**: 4 unit tests (priority cascade, collision handling, etc.)
### 2. Return Jump Emitter
**File**: `src/mir/join_ir/lowering/return_jump_emitter.rs` (354 lines)
- **Purpose**: Reusable return handling helper for Pattern4/5
- **Function**: `emit_return_conditional_jump(loop_step_func, return_info, k_return_id, ...)`
- **Scope**: P1 - unconditional return + conditional (loop_var == N) only
- **Tests**: 3 unit tests (unconditional, no return, conditional)
## Modified Files
**merge/instruction_rewriter.rs** (-15 lines):
- Replaced inline block remapping with `remap_block_id()` call
- Cleaner Branch remap logic
**merge/rewriter/terminator.rs** (-43 lines):
- Delegates remap_jump/remap_branch to block_remapper SSOT
- Simplified duplicate logic
**lowering/loop_with_continue_minimal.rs** (-108 lines):
- Replaced ~100 line return handling with `emit_return_conditional_jump()` call
- Extracted helper functions to return_jump_emitter.rs
- Line reduction: 57% decrease in function complexity
**merge/mod.rs, lowering/mod.rs**:
- Added new module exports (block_remapper, return_jump_emitter)
**phase-284/README.md**:
- Updated completion status (P1 Complete + Refactored)
- Added SSOT consolidation notes
- Documented module architecture
## Code Quality Improvements
| Metric | Before | After | Change |
|--------|--------|-------|--------|
| Duplicate block remap logic | 2 places | SSOT | -15 lines |
| Return handling code | inline (100L) | helper call | -99 lines |
| Testability | Limited | Unit tests (7) | +7 tests |
| Module cohesion | Low (scattered) | High (consolidated) | Better |
## Testing
✅ Build: Success (cargo build --release)
✅ Smoke tests: All pass (46 PASS, 1 pre-existing FAIL)
✅ Regression: Zero
✅ Unit tests: 7 new tests added
## Future Benefits
1. **Pattern5 Reuse**: Direct use of `emit_return_conditional_jump()` helper
2. **Phase 285 (P2)**: Nested if/loop returns via same infrastructure
3. **Maintainability**: SSOT reduces debugging surface area
4. **Clarity**: Each module has single responsibility
## Architectural Notes
**Block Remapper SSOT Rule**:
```
remap_block_id(id, local_block_map, skipped_entry_redirects):
1. Check local_block_map (function-local priority)
2. Fall back to skipped_entry_redirects (global redirects)
3. Return original if not found
```
Prevents function-local block ID collisions with global remap entries.
**Return Emitter Pattern**:
```
emit_return_conditional_jump(func, return_info, k_return_id, alloc_value):
- Pattern1-5: All use same infrastructure
- P1 scope: top-level return only (nested if/loop → P2)
- Returns: JoinInst::Jump(cont=k_return, cond=Some(return_cond))
```

feat(phase284): P1 Complete - Return in Loop with Block Remap Fix
...
## Summary
Completed Phase 284 P1: Enable return statements in Pattern4/5 loops via
JoinInst::Ret infrastructure (100% pre-existing, no new infrastructure needed).
**Critical Bug Fix**: Block ID remap priority
- Fixed: local_block_map must take precedence over skipped_entry_redirects
- Root cause: Function-local block IDs can collide with global remap entries
(example: loop_step:bb4 vs k_exit:bb4 after merge allocation)
- Impact: Conditional Jump else branches were incorrectly redirected to exit
- Solution: Check local_block_map FIRST, then skipped_entry_redirects
## Implementation
### New Files
- `src/mir/join_ir/lowering/return_collector.rs` - Return detection SSOT (top-level only, P1 scope)
- `apps/tests/phase284_p1_return_in_loop_min.hako` - Test fixture (exit code 7)
- Smoke test scripts (VM/LLVM)
### Modified Files
- `loop_with_continue_minimal.rs`: Return condition check + Jump generation
- `pattern4_with_continue.rs`: K_RETURN registration in continuation_funcs
- `canonical_names.rs`: K_RETURN constant
- `instruction_rewriter.rs`: Fixed Branch remap priority (P1 fix)
- `terminator.rs`: Fixed Jump/Branch remap priority (P1 fix)
- `conversion_pipeline.rs`: Return normalization support
## Testing
✅ VM: exit=7 PASS
✅ LLVM: exit=7 PASS
✅ Baseline: 46 PASS, 1 FAIL (pre-existing emit issue)
✅ Zero regression
## Design Notes
- JoinInst::Ret infrastructure was 100% complete before P1
- Bridge automatically converts JoinInst::Ret → MIR Return terminator
- Pattern4/5 now properly merge k_return as non-skippable continuation
- Correct semantics: true condition → return, false → continue loop
## Next Phase (P2+)
- Refactor: Block remap SSOT (block_remapper.rs)
- Refactor: Return jump emitter extraction
- Scope: Nested if/loop returns, multiple returns
- Design: Standardize early exit pattern (return/break/continue as Jump with cond)

Phase 259 P0: Pattern8 (BoolPredicateScan) 完全完了
is_integer/1 を Pattern8 で受理し、VM/LLVM EXE 両方で動作確認完了。
次の大工事（block-parameterized CFG への移行）前のマイルストーンとして記録。
## Key Fixes Applied
1. **skipped_entry_redirects** (instruction_rewriter.rs)
- k_exit のスキップ時、entry block 参照を exit_block_id へリダイレクト
- BasicBlockId not found エラーを根治
2. **loop_var_name** (pattern8_scan_bool_predicate.rs)
- merge_entry_block 選択に使用（`Some(parts.loop_var.clone())`）
- 未設定時の誤った entry block 選択を修正
3. **loop_invariants** (pattern8_scan_bool_predicate.rs)
- PHI-free 不変量パラメータ（`[(me, me_host), (s, s_host)]`）
- loop_var_name 設定時、BoundaryInjector が join_inputs Copy を全スキップするため必要
- Pattern6 と同じ設計（header PHI で不変量を保持）
4. **expr_result** (pattern8_scan_bool_predicate.rs)
- k_exit からの返り値を明示設定（`Some(join_exit_value)`）
- Pattern7 style（推測ではなく明示）
5. **Smoke test scripts**
- set +e パターンで exit code 7 をキャプチャ
- LLVM EXE スクリプトにコメント追加（tools/build_llvm.sh 経由の明記）
## Contract Documentation
- join-explicit-cfg-construction.md に Pattern8 契約の具体例を追加
- "pattern増でも推測増にしない" の実例として記録
- loop_var_name / loop_invariants / expr_result / jump_args_layout の契約を明示
- 20-Decisions.md に正規化（Semantic/Plumbing）の分離方針を追記
- DOCS_LAYOUT.md に重要ドキュメントへの参照を追加
## Test Results
- ✅ VM smoke test: `[PASS] phase259_p0_is_integer_vm` (exit 7)
- ✅ LLVM EXE: tools/build_llvm.sh 経由で exit 7 確認
- ✅ --verify: PASS
## Next FAIL (Phase 260+)
- Function: `Main.main/0` in `apps/examples/json_lint/main.hako`
- Error: `[cf_loop/pattern2] Failed to extract break condition from loop body`
- Pattern: Nested loop（外側 loop + 内側 loop with break）
🚀 次の大工事: block-parameterized CFG への移行を開始します。

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).

refactor(joinir): unify boundary join_inputs SSOT (pattern4/6/7)
...
Apply Phase 256.8 SSOT fix to Pattern4/6/7:
- Use join_module.entry.params.clone() instead of hardcoded ValueIds
- Add fail-fast validation for params count mismatch
- Remove ValueId(0), ValueId(PARAM_MIN + k) patterns
- Clean up unused PARAM_MIN imports
This prevents entry_param_mismatch errors structurally and maintains
consistency with Pattern2/3.
Changes:
- pattern4_with_continue.rs: Lines 442-476 (SSOT extraction + validation)
- pattern6_scan_with_init.rs: Lines 447-471 (SSOT extraction + validation)
- pattern7_split_scan.rs: Lines 495-526 (SSOT extraction + validation)
All patterns now use the same SSOT principle:
1. Extract entry function (priority: join_module.entry → fallback "main")
2. Use params as SSOT: join_inputs = entry_func.params.clone()
3. Build host_inputs in expected order (pattern-specific)
4. Fail-fast validation: join_inputs.len() == host_inputs.len()
Verification:
- cargo build --release: ✅ PASS (no PARAM_MIN warnings)
- Quick profile: ✅ First FAIL still json_lint_vm (baseline maintained)
- Pattern6 smoke: ✅ PASS (index_of test)
- Pattern7 smoke: Pre-existing phi pred mismatch (not introduced by SSOT)

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

fix(normalization): Phase 143 execution fix - Param region SSOT
...
Problem: normalized_helpers allocated env params as ValueId(1,2...)
in PHI Reserved region (0-99) instead of Param region (100-999)
per JoinValueSpace contract.
Root cause: All 4 normalized shadow modules started from
next_value_id=1, violating the Param region contract.
Solution:
- Add NormalizedHelperBox::alloc_env_params_param_region()
that allocates params starting from PARAM_MIN (100)
- Update 4 normalized shadow files to use new API:
- loop_true_if_break_continue.rs
- loop_true_break_once.rs
- if_as_last_join_k.rs
- post_if_post_k.rs
- Fix instruction_rewriter.rs type mismatch
(func.signature.params → func.params)
Verification:
- Unit tests: 69/69 PASS
- VM smoke: exit code 7 ✅
- LLVM EXE smoke: exit code 7 ✅ (timeout resolved!)
ValueId Space Contract (Phase 201):
| Region | Range | Purpose |
|--------------|----------|------------------------------|
| PHI Reserved | 0-99 | Loop header PHI dst |
| Param | 100-999 | env params (flag, counter) |
| Local | 1000+ | Const, BinOp, condition |

fix(joinir): Phase 132 P1 - k_exit continuation classification fix
...
Problem: k_exit with TailCall(post_k) was classified as skippable continuation,
causing post_k block to become unreachable.
Root cause:
- Continuation classification was name-based ("join_func_2")
- Skippable continuation check didn't examine function body
- k_exit with tail call to post_k had its block skipped during merge
Solution:
- Check function body structure before classifying as skippable
- Non-skippable pattern: continuation with TailCall to another function
- Properly emit tail call as Jump instruction
Changes:
- src/mir/builder/control_flow/joinir/merge/mod.rs:
- Add structural check in is_skippable_continuation()
- Detect TailCall(other_func) pattern
- Skip only if function is truly empty (1 block, Return only)
- src/mir/builder/control_flow/joinir/merge/instruction_rewriter.rs:
- Improve k_exit continuation handling
- Properly rewrite TailCall → Jump for post_k
Test results:
- Phase 132 LLVM EXE: PASS (exit code 3)
- Phase 132 VM: PASS
- Phase 131 regression: PASS
- Phase 97 regression: PASS

refactor(joinir): extract ExitArgsCollectorBox for jump_args SSOT
...
Phase 118 refactoring: Box modularization for exit value collection.
# Changes
- Created `exit_args_collector.rs` with ExitArgsCollectorBox
- Extracted jump_args processing logic from instruction_rewriter.rs
- Implemented SSOT for offset calculation (0 vs 1 legacy layout)
- Added comprehensive unit tests (6 tests, all passing)
# Design
- **Responsibility**: Collects exit PHI inputs + carrier inputs from jump_args
- **SSOT**: Centralized offset calculation logic
- **Fail-Fast**: Validates jump_args length against exit_bindings
- **Phase 118 P2 Contract**: Uses boundary.exit_bindings as SSOT
# Key Features
- Filters ConditionOnly carriers (no exit PHI needed)
- Handles both direct mapping (offset=0) and legacy layout (offset=1)
- Strict mode: Fail-Fast on validation errors
- Non-strict mode: Warns and continues with best effort
# Test Results
- Unit tests: 6/6 PASS
- Phase 118 smoke tests: PASS (VM + LLVM)
- Phase 117 regression: PASS
# Reduced Code Complexity
- instruction_rewriter.rs: ~90 lines → ~25 lines (box call)
- Offset logic: Centralized in ExitArgsCollectorBox

## アーキテクチャ設計
### 変数解決メカニズム
```rust
// Priority 1: ConditionEnv (loop params, captured)
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); }
}
```

feat(mir): Phase 136 Step 2/7 - CoreContext extraction complete
...
Extract core ID generation fields from MirBuilder to improve organization:
- value_gen: ValueIdGenerator
- block_gen: BasicBlockIdGenerator
- next_binding_id: u32 (Phase 74)

Implementation:
- Created src/mir/builder/core_context.rs (215 lines)
- Added core_ctx field to MirBuilder as SSOT
- Deprecated legacy fields with backward compat
- ID allocation methods use core_ctx and sync legacy fields
- Added next_block_id() helper, replaced 30+ block_gen.next() calls
Testing:
- cargo build --release: SUCCESS (193 warnings expected)
- cargo test --release --lib: 1004/1004 PASS (+7 tests)
- phase135_trim_mir_verify.sh: PASS
- phase132_exit_phi_parity.sh: 3/3 PASS

feat(joinir): Phase 135 P1 - Contract checks Fail-Fast (二度と破れない設計)
...
## Summary
Adds early Fail-Fast contract verification to prevent Phase 135 P0 issues from recurring.
Two new verifiers catch allocator SSOT violations and boundary inconsistencies before --verify.
## Changes
### Step 1: verify_condition_bindings_consistent
**Location**: `src/mir/builder/control_flow/joinir/merge/contract_checks.rs`
**Contract**: condition_bindings can have aliases (multiple names for same join_value),
but same join_value with different host_value is a violation.
**Example Error**:
```
[JoinIRVerifier/Phase135-P1] condition_bindings conflict:
join_value ValueId(104) mapped to both ValueId(12) and ValueId(18)
```
**Catches**: ConditionLoweringBox bypassing SSOT allocator before BoundaryInjector
### Step 2: verify_header_phi_dsts_not_redefined
**Location**: `src/mir/builder/control_flow/joinir/merge/contract_checks.rs`
**Contract**: Loop header PHI dst ValueIds must not be reused as dst in non-PHI instructions.
Violation breaks MIR SSA (PHI dst overwrite).
**Example Error**:
```
[JoinIRVerifier/Phase135-P1] Header PHI dst ValueId(14) redefined by non-PHI instruction in block 3:
Instruction: Call { dst: Some(ValueId(14)), ... }
```
**Catches**: ValueId collisions between header PHI dsts and lowered instructions
### Integration
**Location**: `src/mir/builder/control_flow/joinir/merge/mod.rs`
Added to `verify_joinir_contracts()`:
1. Step 1 runs before merge (validates boundary)
2. Step 2 runs after merge (validates func with PHI dst set)
### Documentation
- Updated `phase135_trim_mir_verify.sh` - Added P1 contract_checks description
- Updated `phase-135/README.md` - Added P1 section with contract details and effects
## Acceptance
✅ Build: SUCCESS
✅ Smoke: phase135_trim_mir_verify.sh - PASS
✅ Regression: phase132_exit_phi_parity.sh - 3/3 PASS
✅ Regression: phase133_json_skip_whitespace_llvm_exe.sh - PASS
## Effect
- **Prevention**: Future Box implementations catch SSOT violations immediately
- **Explicit Errors**: Phase 135-specific messages instead of generic --verify failures
- **Unbreakable**: Debug builds always detect violations, enforced by CI/CD

feat(joinir): Phase 132-P3 - Exit PHI collision early detection
...
Added verify_exit_phi_no_collision() to contract_checks.rs for early detection
of ValueId collisions between exit PHIs and other instructions.
Problem detected:
- If exit_phi_builder uses builder.value_gen.next() (module-level) instead of
func.next_value_id() (function-level), ValueIds can collide:
Example:
- bb0: %1 = const 0 (counter init)
- bb3: %1 = phi ... (exit PHI - collision!)
Previous behavior:
- Error only detected at LLVM backend runtime
- Cryptic error: "Cannot overwrite PHI dst=1"
New behavior:
- Panic at Rust compile time (debug build)
- Clear error message with fix suggestion:
"Exit PHI dst %1 collides with instruction in block 0
Fix: Use func.next_value_id() in exit_phi_builder.rs"
Benefits:
- 🔥 Fail-Fast: Catch errors during Rust compilation, not LLVM execution
- 📋 Clear messages: Exact collision point + fix suggestion
- 🧪 Testable: verify_exit_phi_no_collision() can be unit tested

fix(joinir): Phase 132-P2 - Exit PHI ValueId collision fix
...
Root cause: exit_phi_builder.rs used builder.value_gen.next() (module-level counter)
instead of func.next_value_id() (function-level counter) for allocating exit PHI dst.
This caused ValueId collisions in functions like:
- bb0: %1 = const 0 (initial counter value)
- bb3: %1 = phi ... (exit PHI - collision!)
The LLVM backend then failed with:
"Cannot overwrite PHI dst=1. ValueId namespace collision detected."
Fix: Use func.next_value_id() to allocate from the function's local counter,
ensuring unique ValueIds within each function.
Verified:
- Pattern 1 (simple while): VM RC:3, LLVM RC:3 ✅
- Case C (Pattern 5): VM returns 3, LLVM Result: 3 ✅

feat(llvm): Phase 131-11-H/12 - ループキャリアPHI型修正 & vmap snapshot SSOT
...
## Phase 131-11-H: ループキャリアPHI型修正
- PHI生成時に初期値（entry block）の型のみ使用
- backedge の値を型推論に使わない（循環依存回避）
- NYASH_CARRIER_PHI_DEBUG=1 でトレース
## Phase 131-12-P0: def_blocks 登録 & STRICT エラー化
- safe_vmap_write() で PHI 上書き保護
- resolver miss を STRICT でエラー化（フォールバック 0 禁止）
- def_blocks 自動登録
## Phase 131-12-P1: vmap_cur スナップショット実装
- DeferredTerminator 構造体（block, term_ops, vmap_snapshot）
- Pass A で vmap_cur をスナップショット
- Pass C でスナップショット復元（try-finally）
- STRICT モード assert
## 結果
- ✅ MIR PHI型: Integer（正しい）
- ✅ VM: Result: 3
- ✅ vmap snapshot 機構: 動作確認
- ⚠️ LLVM: Result: 0（別のバグ、次Phase で調査）
