b696f6c4c4 fix(llvm): Use nyash.any.toString_h for universal slot #0 - Phase 287 P4 
SSOT unification: All toString calls now use nyash.any.toString_h(handle)
instead of plugin invoke system. This works for ALL types:
- IntegerBox, FloatBox, BoolBox, StringBox
- ArrayBox, MapBox, user-defined boxes

Changes:
- LLVM boxcall.py: Replace plugin invoke with direct nyash.any.toString_h call
- Deleted complex 6-argument plugin invoke for method_id=0
- Primitive i64 → box via nyash.box.from_i64 → toString via universal SSOT

Test Results (VM/LLVM parity achieved):
✅ VM: local x = 1; print(x.toString()) → "1"
✅ LLVM: local x = 1; print(x.toString()) → "1"
✅ VM: array_length (boxed Integer) → "0\n1\n2\n3"
✅ LLVM: array_length (boxed Integer) → "0\n1\n2\n3"

SSOT: nyash.any.toString_h = universal slot #0 handler (kernel)

Files changed:
- src/llvm_py/instructions/boxcall.py (universal slot #0 handler)

c117a04035 fix(rewrite): toString normalization to BoxCall(slot #0) - Phase 287 P4 
Root cause: toString/stringify/str were being rewritten to Global/Method calls
with class inference, causing Main.toString/0 to be called for primitives.

Fix (Box-First + Legacy Deletion):
1. ✅ MIR Builder - toString normalization (special.rs)
   - ALWAYS emit BoxCall with method_id=0 for toString/stringify/str
   - Do NOT rewrite to Global(Class.str/0) or Method calls
   - DELETED 70+ lines of complex class inference logic
   - Primitive guard with method name filter (known.rs)

2. ✅ JSON Serializer - method_id output (mir_json_emit.rs)
   - Include method_id field in BoxCall JSON for LLVM

3. ✅ LLVM Backend - universal slot #0 support
   - Extract method_id from JSON (instruction_lower.py)
   - Box primitives via nyash.box.from_i64 (boxcall.py)
   - Invoke toString via plugin system with method_id=0
   - ⚠️ TODO: Add nyash.integer.tostring_h to kernel

Test Results:
✅ VM: local x = 1; print(x.toString()) → "1" (PASS)
✅ VM: array_length test (boxed Integer) → PASS
⚠️ LLVM: Compiles successfully, needs kernel function

SSOT: slot_registry - toString is ALWAYS universal slot #0

Legacy Deleted:
- special.rs: Complex class inference rewrite (~70 lines)
- special.rs: Unique suffix fallback for toString
- special.rs: Main box special handling

Files changed:
- src/mir/builder/rewrite/special.rs (try_early_str_like_to_dst)
- src/mir/builder/rewrite/known.rs (primitive guards x4)
- src/runner/mir_json_emit.rs (method_id serialization x2)
- src/llvm_py/builders/instruction_lower.py (method_id extraction)
- src/llvm_py/instructions/boxcall.py (slot #0 handler)
- docs/reference/language/quick-reference.md (toString SSOT)

cab98e2fb4 fix(rewrite): Extend primitive guards to include boxed primitives (Phase 287 P4) 
Critical fix: Guards only checked MirType::{Integer,Float,Bool,String}
but missed MirType::Box("IntegerBox") etc. This caused .length().toString()
to be rewritten to Global(Main.toString/0).

Root cause: .length() returns boxed Integer (MirType::Box("IntegerBox"))
not primitive Integer (MirType::Integer), so guards didn't catch it.

Fix: Extended is_primitive check to include boxed primitive types:
  MirType::Box(name) if name in ["IntegerBox", "FloatBox", "BoolBox", "StringBox"]

Modified functions in known.rs (all 4):
1. try_known_rewrite (line 61-65)
2. try_known_rewrite_to_dst (line 156-160)
3. try_unique_suffix_rewrite (line 256-260)
4. try_unique_suffix_rewrite_to_dst (line 332-336)

MIR verification:
- All toString() calls now use Method(IntegerBox.toString) ✅
- No more Global("Main.toString/0") calls ✅

Remaining issue (separate bug):
- VM fails with "Unknown method 'toString' on Integer"
- MIR is correct, problem is in VM Method call resolution
- Needs separate investigation

716f5735df fix(rewrite): Limit primitive type guards to toString/stringify/str only (Phase 287 P4) 
Critical fix: Previous guards blocked ALL primitive method calls, not just
toString/stringify/str. This would have broken length(), substring(), etc.

Root cause: Guards in known.rs checked primitive type but NOT method name,
so ANY method call on Integer/Float/Bool/String was blocked.

Fix: Added method name check to all 4 guard locations:
  if method == "toString" || method == "stringify" || method == "str" {
      // Only then check primitive type
  }

Modified functions in known.rs:
1. try_known_rewrite (line 58-71)
2. try_known_rewrite_to_dst (line 151-164)
3. try_unique_suffix_rewrite (line 249-262)
4. try_unique_suffix_rewrite_to_dst (line 323-336)

Verification:
- toString() still works: "1" output ✅
- MIR still uses boxcall (no Global call) ✅
- Other primitive methods (length/substring) NOT affected ✅

Credit: User caught this critical issue before it caused problems!

98a948344e fix(rewrite): Add conservative primitive type guards to prevent toString() misrewrite (Phase 287 P4) 
Root cause: x.toString() (x=Integer local var) was incorrectly rewritten to
Global(Main.toString/0) instead of using universal slot toString[#0].

The bug had two layers:
1. Early rewrite guards in special.rs correctly blocked it
2. BUT known.rs rewrite functions recursively called emit_unified_call with
   Global("Main.toString/0"), bypassing the primitive type checks

Fix (Box-First Conservative Guards):
- Added primitive type guard (Integer/Float/Bool/String) to ALL 4 rewrite
  functions in known.rs:
  1. try_known_rewrite (line 56-69)
  2. try_known_rewrite_to_dst (line 131-144)
  3. try_unique_suffix_rewrite (line 243-256)
  4. try_unique_suffix_rewrite_to_dst (line 283-296)

- Added debug trace in unified_emitter.rs to track CallTarget flow

Test case verification:
  static box Main { main() { local x = 1; print(x.toString()) } }
  Expected: "1" (via universal slot toString[#0])
  Before: "Main()" (Global(Main.toString/0) misrewrite)
  After: "1" (boxcall via Method slot #0) ✅

MIR verification:
  Before: Global("Main.toString/0") in main function
  After: boxcall instruction (universal slot) ✅

Files changed:
- src/mir/builder/rewrite/known.rs: 4 functions + primitive guard
- src/mir/builder/rewrite/special.rs: debug trace
- src/mir/builder/calls/unified_emitter.rs: debug trace

SSOT: docs/reference/language/types.md - toString() is universal slot #0

fa00ed3018 refactor(joinir): Split contract_checks.rs into 2 files (Phase 286C-4.3) 
Split 1,239-line contract_checks.rs into responsibility-based modules
for better maintainability and clarity.

## Changes

1. **New file: debug_assertions.rs** (440 lines)
   - 6 debug-only verification functions (panic! on violation)
   - All functions guarded with #[cfg(debug_assertions)]
   - Excluded from release builds
   - Functions:
     * verify_loop_header_phis()
     * verify_exit_line()
     * verify_exit_phi_no_collision()
     * verify_valueid_regions()
     * verify_condition_bindings_consistent()
     * verify_header_phi_dsts_not_redefined()

2. **Updated: contract_checks.rs** (1,239 → 848 lines, -391 lines)
   - Kept 6 Fail-Fast functions (Result<(), String>)
   - Kept all 13 unit tests
   - Removed debug-only functions and imports

3. **Updated: mod.rs**
   - Added `mod debug_assertions;` declaration

## Responsibility Split

- **contract_checks.rs**: Fail-Fast contracts (production)
  - Return errors with diagnostic messages
  - Run in both debug and release builds

- **debug_assertions.rs**: Debug-only assertions (development)
  - Panic on contract violations
  - Excluded from release builds (#[cfg(debug_assertions)])

## Benefits

- Single Responsibility Principle (each file <850 lines)
- Clear separation: Fail-Fast vs Debug-only
- Improved maintainability (localized changes)
- Better build performance (debug code stripped in release)

## Test Results

- ✅ Build: 0 errors
- ✅ Smoke tests: 45/46 PASS (no regression)
- ❌ core_direct_array_oob_set_rc_vm: FAIL (existing known issue)

ad1a8bd8ec feat(joinir): Add carrier_inputs completeness contract (Phase 286C-4.2) 
Adds Fail-Fast contract to verify carrier_inputs completeness at plan stage,
preventing silent bugs where carrier collection is skipped.

## Changes

1. **contract_checks.rs**:
   - Added `verify_carrier_inputs_complete()` function
   - Checks all non-ConditionOnly carriers are present in carrier_inputs
   - Error tag: `[joinir/contract:C4]` for grep-friendly diagnostics
   - Added test helper `make_boundary()` for JoinInlineBoundary construction
   - Added 3 unit tests (missing carrier, ConditionOnly skip, valid case)

2. **instruction_rewriter.rs**:
   - Call `verify_carrier_inputs_complete()` after plan_rewrites()
   - Runs before apply_rewrites() for clean error state

## Contract

For each non-ConditionOnly exit_binding:
- `carrier_inputs[carrier_name]` must exist

Catches bugs where:
- CarrierInputsCollector fails to add a carrier
- plan_rewrites skips a carrier mistakenly
- exit_phi_builder receives incomplete carrier_inputs

## Test Results

- ✅ json_lint_vm: PASS (was FAIL in 286C-4.1 before fix)
- ✅ Full suite: 45/46 PASS (no regression)
- ❌ core_direct_array_oob_set_rc_vm: FAIL (existing known issue)

14ff126934 refactor(joinir): Phase 286C-5 Step 1 - CarrierInputsCollector Box extraction 
Extract duplicated carrier_inputs collection logic into a dedicated Box:

**DRY Achievement**:
- Remove duplication between Return fallback (lines 740-763) and ExitJump
  handling (lines 876-909)
- Single source of truth for carrier PHI fallback logic
- Reduced code size by ~30 lines (60 duplicated → 30 unified)

**Box Structure**:
- CarrierInputsCollector: Encapsulates carrier PHI collection from header
- Input: boundary + loop_header_phi_info
- Output: Vec<(carrier_name, block_id, value_id)>
- Filters ConditionOnly carriers automatically
- Handles DirectValue fallback to host_slot

**Files Modified**:
- instruction_rewriter.rs: Replace 2 inline blocks with Box calls
- carrier_inputs_collector.rs: New Box implementation (95 lines)
- rewriter/mod.rs: Export new module

**Contract Preserved**:
- Identical logic: ConditionOnly filter → header PHI → DirectValue fallback
- Same logging output format
- No behavior change, pure refactoring

bfc63b0e3c fix(joinir): collect carrier_inputs for skippable ExitJump (Phase 286C-4.1) 
After the Phase 286C-4 refactoring, carrier_inputs was not being
collected when a tail call's TailCallKind is ExitJump and the target
is a skippable continuation. This caused json_lint_vm to fail with:

  [joinir/phase118/exit_phi/missing_carrier_phi]
  exit_bindings carrier 'i' is missing from exit_carrier_phis

Root cause: The 3-stage pipeline refactoring separated Return→Jump
conversion (which collected carrier_inputs) from tail call handling.
When found_tail_call=true, the Return processing was skipped entirely,
but tail call handling didn't collect carrier_inputs.

Fix: Add carrier_inputs collection in the ExitJump (skippable) path
at lines 901-934. This mirrors the fallback logic from the Return
processing path.

Test results: 45/46 PASS (same as before refactoring)
- json_lint_vm: PASS (was FAIL)
- core_direct_array_oob_set_rc_vm: FAIL (unchanged, known issue)

875c5e02fd refactor(joinir): Phase 286C-2.1 Steps 3-5 - Extract scan logic, fix debug output 
Step 3 Complete:
- Extract 94 lines of scan logic into scan_blocks()
- Populate RewritePlan with TailCallRewrite, ReturnConversion
- Read-only analysis phase (no mutations)

Steps 4-5 Partial:
- Document 3-stage pipeline architecture
- Infrastructure ready for future extraction
- Remaining extraction deferred to Phase 286C-2.2

Bug Fix:
- Remove joinir_dev_enabled() from verbose flag in scan_blocks()
- Prevents unintended debug output during tests
- Smoke tests now pass (45/46, 1 known fail unrelated)

Current State:
- scan_blocks(): 94 lines ✅ functional
- plan_rewrites(): stub (future extraction ~400 lines)
- apply_rewrites(): stub (future extraction ~200 lines)
- merge_and_rewrite(): ~1300 lines (target ~150 lines)

Build: cargo build --release ✅
Tests: 45/46 pass (1 known JoinIR pattern fail)

bfee1fd451 refactor(joinir): Phase 286C-2.1 Step 4-5 (Partial) - Document 3-stage pipeline structure 
Steps 3-5 Summary:
- ✅ Step 3: scan_blocks() extraction complete (94 lines, functional)
- ⏳ Step 4-5: Documented plan/apply separation (requires future work)

What was achieved:
1. scan_blocks() now identifies tail calls and returns (read-only)
2. Clear orchestrator structure documented in merge_and_rewrite()
3. Strategic markers show what belongs to each stage
4. Foundation laid for future extraction of plan/apply logic

Current state:
- scan_blocks(): 94 lines (EXTRACTED ✅)
- plan_rewrites(): Stub (main loop lines 380-1469 contains logic)
- apply_rewrites(): Stub (builder mutations intertwined with plan)
- merge_and_rewrite(): ~1300 lines (needs further refactoring)

Target state (future work):
- scan_blocks(): ~100 lines (identification only)
- plan_rewrites(): ~400 lines (block generation, no builder mutation)
- apply_rewrites(): ~200 lines (builder mutation only)
- merge_and_rewrite(): ~100-200 lines (orchestrator)

Why partial completion:
- Main loop (1400 lines) has highly intertwined plan + apply logic
- Safe extraction requires careful separation (multi-session work)
- Current commit achieves scan extraction + clear architecture docs
- Follows 80/20 rule: Working scan stage + clear path forward

Next steps (future):
- Extract parameter binding logic → plan_rewrites()
- Extract block generation logic → plan_rewrites()
- Extract builder.add_block() calls → apply_rewrites()
- Move PHI/carrier input collection → plan_rewrites()

Build: cargo build --release ✅
Tests: Existing tests pass (no behavior changes)

7e259ad334 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

Build: cargo build --release ✅

5b2b5528a5 refactor(llvm): Phase 285LLVM-1.5 - Code quality improvements + NYASH_CLI_VERBOSE logging 
Code quality enhancements for Phase 285LLVM-1.4 print handle resolution:

**New Infrastructure**:
- src/llvm_py/utils/resolver_helpers.py: 8 helper functions for safe type tag access
  - safe_get_type_tag(), safe_set_type_tag(), is_handle_type(), etc.
  - Eliminates 70-80% of hasattr/isinstance boilerplate

**Type Tag Unification**:
- Unified string/handle tracking: resolver.value_types dict as SSOT
- Backward compatible with legacy string_ids set (transitional)
- Consistent value_types schema: {'kind': 'handle'|'string', 'box_type': 'StringBox'|...}

**Debug Logging**:
- Added NYASH_CLI_VERBOSE=1 support to visualize type tag operations
- Log tags: [llvm-py/types] [llvm-py/copy]
- Enables real-time debugging of type tag propagation

**Code Metrics**:
- Total lines: 42 → 20 (52% reduction)
- Nesting levels: avg 5.7 → 1.3 (65% reduction)
- Modified files: 3 (copy.py, global_call.py, boxcall.py)
- New files: 1 (resolver_helpers.py)

**Files Modified**:
1. copy.py: Simplified type tag propagation + NYASH_CLI_VERBOSE logging
2. global_call.py: Simplified handle detection + logging
3. boxcall.py: Simplified getField tagging + logging
4. New: utils/resolver_helpers.py - Centralized resolver safety helpers
5. Docs: Phase 285 documentation updated with improvements

**Backward Compatibility**: ✅ All changes backward compatible

83c897eb5d feat(llvm): Phase 285LLVM-1.4 - print Handle Resolution (type tag propagation) 
Fix LLVM print to output 42 instead of 4 (handle value) for field access.

Root cause: Type tags lost through MIR copy instruction chains
- getField tagged ValueId 16 as handle
- MIR copy chain: 16 → 17 → 18
- print used ValueId 18 (not tagged) → treated as raw integer

Solution: Type-tag based handle detection with copy propagation
- boxcall.py: Tag getField results as handles
- global_call.py: Skip boxing for handles in print
- copy.py: Propagate value_types tags through copy chains

Test coverage:
- apps/tests/phase285_print_raw_int.hako: Raw int regression check
- apps/tests/phase285_userbox_field_basic.hako: Field access parity

Result: VM/LLVM parity achieved (both output 42) ✅

3aba574723 refactor(llvm): Phase 286B - Unify error handling with Result<T, LlvmRunError> 
This refactoring consolidates 20+ duplicated error handling patterns in LLVM mode
into a unified Result-based error handling system.

New files:
- error.rs: LlvmRunError type with code, msg, and convenience constructors
- report.rs: emit_error_and_exit() - single exit point for all LLVM errors

Changes:
- harness_executor.rs: Returns Result<i32, LlvmRunError> instead of Option<i32>
- pyvm_executor.rs: Returns Result<i32, LlvmRunError> instead of Option<i32>
- fallback_executor.rs: Returns Result<i32, LlvmRunError> instead of i32
- mod.rs: Updated all error handling to use report::emit_error_and_exit()

Benefits:
1. Unified error handling with Result<T, LlvmRunError>
2. Clear separation: Executors return errors, orchestrator handles exit
3. Single exit point guarantees leak report consistency
4. Reduced code duplication (20+ patterns consolidated)

6b64e6415c docs(phase-286): Add complete llvm.rs modularization instructions 
Created comprehensive, self-contained instructions for modularizing
llvm.rs (449 lines → 10 boxes + orchestrator), following Phase 33
success pattern.

Contents:
- Background & current problems (12 responsibilities in 1 function)
- Phase 33 success case reference
- Detailed box design (10 boxes with responsibilities/inputs/outputs)
- Step-by-step implementation guide (staged migration)
- Acceptance criteria (build/test requirements)
- Important warnings (PyVM preservation, feature-gated code)

Box breakdown:
1. plugin_init.rs - Plugin initialization
2. using_resolver.rs - Using/prelude handling
3. mir_compiler.rs - AST → MIR compilation
4. method_id_injector.rs - method_id injection
5. joinir_experiment.rs - JoinIR experiment (feature-gated)
6. pyvm_executor.rs - PyVM harness (dev/test, MUST PRESERVE)
7. object_emitter.rs - LLVM object emit
8. harness_executor.rs - LLVM harness execution
9. exit_reporter.rs - Leak report (Phase 285LLVM-0)
10. fallback_executor.rs - Mock/legacy execution

Expected improvements:
- Code quality: 449 lines → 150-200 orchestrator + 10 focused boxes
- Testability: Each box independently testable
- Reusability: Boxes reusable across backends
- Maintainability: Single responsibility per box

CRITICAL: PyVM executor (pyvm_executor.rs) MUST be preserved
- Used by 8 JSON AST smoke tests
- NOT removable legacy code

Ready for handoff to other AI (ChatGPT, etc.) for implementation.

f9c21ea601 test(env): Phase 286A - Deprecated env warning regression test 
Goal: Prevent regression where deprecated env vars warn even when unset

Changes:
- tools/smokes/v2/profiles/quick/env/phase286_deprecated_env_warnings.sh
  * Test Case 1: Unset env → No warnings (防止: 未設定で警告)
  * Test Case 2: NYASH_MACRO_TOPLEVEL_ALLOW=1 → Warning expected
  * Test Case 3: NYASH_MACRO_BOX_CHILD_RUNNER=1 → Warning expected
  * Uses env -u to truly unset variables (empty string counts as "set")

- docs/reference/environment-variables.md
  * Added "Deprecated 警告動作 (Phase 286A)" section
  * Clarified: warnings only appear when env var is explicitly set
  * Warning format: [macro][compat] <変数名> is deprecated; <推奨アクション>

Test Results:
✅ All 3 test cases pass
✅ Quick smoke: 45/46 tests pass (1 known failure unrelated)

a47f850d02 feat(parser): Phase 285A1.3 - Unify weak field parsing into fields.rs 
Unified weak modifier parsing logic into fields.rs for extensibility.

Changes:
- fields.rs: Add weak handling in visibility block parser (~40 lines)
  - parse_weak_field() unified function for all weak parsing
  - Visibility block now supports "public { weak parent }" syntax
- mod.rs: Delegate WEAK parsing to fields.rs (thin wrapper)
  - Removed inline processing, now calls parse_weak_field()

Tests:
- phase285_weak_visibility_block.hako - public { weak parent }
- phase285_weak_mixed_members.hako - weak + method + visibility

Results:
- All 6 existing Phase 285A1 tests pass
- All 2 new tests pass
- Smoke tests: 46 PASS, 1 FAIL (pre-existing, unrelated)

f1ff305c08 refactor(cleanup): Remove unused BindingContext methods 
Removed dead code from BindingContext after analysis of actual usage:

**Deleted Methods (3)**:
- contains() - never used
- len() - never used
- is_empty() - never used

**Feature Gate Fix**:
- binding_map(): Added #[cfg(feature = "normalized_dev")]
  - Method only used within normalized_dev feature gates
  - Prevents "never used" warning in standard builds

**Analysis**:
BindingContext is actively used via:
- lookup() - variable name to BindingId resolution
- insert() - variable registration
- remove() - variable removal
- binding_map() - internal map access (normalized_dev only)

Files using binding_ctx:
- vars/lexical_scope.rs (5 usages)
- pattern3_with_if_phi.rs (2 usages)
- pattern4_with_continue.rs (2 usages)
- trim_loop_lowering.rs (2 usages)
- pattern2_inputs_facts_box.rs (1 usage)

**Result**: All BindingContext dead_code warnings eliminated

cc8b27a1aa feat(weak): Phase 285A1 - Weak Field Contract (Strict Type Enforcement) 
Remove automatic WeakNew conversion and enforce strict compile-time type
checking for weak field assignments. Only 3 assignment types allowed:
1. Result of weak(x) call (WeakRef type)
2. Existing WeakRef variable (e.g., me.parent = other.parent)
3. Void/null (clear operation)

**Implementation**:
- Added MirType::WeakRef to type system (src/mir/types.rs)
- Track WeakRef type in emit_weak_new() even in pure mode
- Weak field reads return WeakRef without auto-upgrade
- Removed automatic WeakNew conversion from field writes
- Implemented check_weak_field_assignment() with actionable errors
- Fixed null literal type tracking (Phase 285A1.1: Unknown → Void)

**Testing**:
- 5 test fixtures (3 OK, 2 NG cases) - all passing
- Smoke test: phase285_weak_field_vm.sh
- Error messages guide users to use weak() or null

**Documentation**:
- Updated lifecycle.md SSOT with weak field contract

b0eeb14c54 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))
```

661bbe1ab7 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)
