fix(pattern2): abort entire Pattern2 on unpromoted LoopBodyLocal instead of partial execution
...
Phase 263 P0: Pattern2 で処理できない LoopBodyLocal を検出したら Pattern2 全体を早期終了
Changes:
- promote_step_box.rs: 戻り値を Result<Option<_>, String> に変更
- Reject を二分化: 対象外（not_readonly等）→ Ok(None)、対象だが未対応 → Err
- pattern2_lowering_orchestrator.rs: Ok(None) 検出で早期 return
- apps/tests/phase263_p0_pattern2_seg_min.hako: test simplification
後続経路（legacy binding等）へ fallback させる（detection→extract→lower SSOT 維持）
Fail-Fast 原則: 対象外は Ok(None) で後続経路へ、対象だが未対応は Err で即座に失敗
Fixes: core_direct_array_oob_set_rc_vm smoke test FAIL

refactor(mir): phase260 p0.2 hide legacy edge-args reads behind BasicBlock API
...
- Add block.return_env() getter for Return env metadata
- Update instruction_rewriter.rs to use block.return_env()
- Update exit_collection.rs to use block.return_env()
- Prepare for Phase 260 P2 (jump_args deletion)
This consolidates all legacy edge-args reads through BasicBlock API,
enabling clean deletion of jump_args field in P2.

- Fix helpers.rs tests to use new MirFunction::new(FunctionSignature, BasicBlockId) API
- Update continuation_contract.rs import path to use rewriter::helpers
- Add TODO comment for future exit_collection integration
- All 6 rewriter tests pass
The exit_collection module is complete and tested but full integration
with instruction_rewriter.rs deferred (80/20 rule - logging context
and flow control require careful refactoring).

refactor(joinir): Phase 260 P0.1 Step 6 - extract exit_collection.rs
...
Extract exit value collection logic from instruction_rewriter.rs into
dedicated rewriter/exit_collection.rs module (~305 lines).
New functions:
- collect_exit_values_from_legacy_edge_args(): Phase 246-EX collection
- add_carrier_values_to_inputs(): carrier values → carrier_inputs map
- handle_fallback_exit_collection(): Phase 246-EX/131 P1.5 fallback
- collect_k_exit_values(): k_exit tail call lowering (Phase 131)
Key changes:
- ExitCollectionResult struct for structured return values
- Uses Vec<(String, (BasicBlockId, ValueId))> for carrier_values
(matching ExitArgsCollectorBox output format)
- Logging removed from helpers (caller handles via local log! macro)
- 3 unit tests for add_carrier_values_to_inputs

refactor(joinir): Phase 260 P0.1 Step 5 - Extract terminator.rs (Jump/Branch remapping)
...
Extract Jump/Branch terminator remapping to dedicated module.
3 clean functions: remap_jump, remap_branch, apply_remapped_terminator.
Changes:
- NEW: rewriter/terminator.rs - 3 functions (145 lines)
- remap_jump(): Jump block ID + edge_args remapping
- remap_branch(): Branch block ID + condition + edge_args remapping
- apply_remapped_terminator(): Apply remapped terminator with edge_args handling
- CHANGED: instruction_rewriter.rs - use terminator module (deleted local logic)
- Deleted remap_edge_args closure (lines 902-911)
- Replaced Jump remapping (lines 1056-1067) → remap_jump()
- Replaced Branch remapping (lines 1069-1094) → remap_branch()
- Replaced terminator setting (lines 1098-1127) → apply_remapped_terminator()
- CHANGED: rewriter/mod.rs - declare terminator module
Benefits:
- Phase 259 P0 FIX: skipped_entry_redirects handling centralized
- Testable in isolation (pure block ID/ValueId mapping)
- Reduces instruction_rewriter.rs by ~40 lines
Reduction:
- instruction_rewriter.rs: 1396 → ~1356 lines (-40)
Next: Extract exit_collection.rs (Return→Jump + exit value collection)

refactor(joinir): Phase 260 P0.1 Step 4 - Extract type_propagation.rs (70 lines)
...
Extract propagate_value_type_for_inst to dedicated type_propagation module.
Handles type info flow from JoinIR→MIR merge (SSOT + fallback inference).
Changes:
- NEW: rewriter/type_propagation.rs - propagate_value_type_for_inst
- CHANGED: instruction_rewriter.rs - import from type_propagation (deleted local fn)
- CHANGED: rewriter/mod.rs - declare type_propagation module
Design:

Small pure function (12 lines) with comprehensive tests (3 test cases).
Changes:
- NEW: rewriter/helpers.rs - is_skippable_continuation + 3 tests
- CHANGED: instruction_rewriter.rs - import from helpers (deleted local definition)
- CHANGED: rewriter/mod.rs - re-export from helpers
Benefits:
- Testable in isolation (pure function)

Changes:
- NEW: rewriter/logging.rs - log_if() + rewriter_log!() macro
- CHANGED: rewriter/mod.rs - declare logging module
Design:
- log_if(trace, enabled, msg): Function form for explicit control
- rewriter_log!(): Macro form for format!() convenience
- Both wrap JoinLoopTrace::stderr_if() (existing infrastructure)
Status:
- instruction_rewriter.rs still uses local log! macro (unchanged)

This enables gradual refactoring without breaking existing code.
Changes:
- NEW: src/.../joinir/merge/rewriter/mod.rs (re-exports instruction_rewriter)
- CHANGED: merge/mod.rs - route calls through rewriter module
- STRATEGY: Keep instruction_rewriter.rs intact, split later into:
- terminator.rs (Branch/Jump/Return remapping)

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).

P1.1: Pattern6 false positive fix (SSOT approach)
- can_lower() now calls extract_scan_with_init_parts() for SSOT
- index_of_string/2 no longer triggers false positive
- Graceful fall-through with Ok(None)
P1.2: LoopHeaderPhi CFG-based correction
- Step 0: Manual successor update from terminators

Extend Pattern6 (ScanWithInit) to handle both forward and reverse scans:
- Forward: i=0, loop(i < len), i=i+1 (existing)
- Reverse: i=len-1, loop(i >= 0), i=i-1 (NEW)
Implementation:
- Added ScanDirection enum (Forward/Reverse)
- Updated extract_scan_with_init_parts() to detect both patterns
- Created lower_scan_with_init_reverse() lowerer
- Pattern6 now selects appropriate lowerer based on scan direction

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)

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

feat(anf): Phase 145 P0/P1/P2 - ANF (A-Normal Form) transformation
...
Implement ANF transformation for impure expressions to fix evaluation order:
Phase 145 P0 (Skeleton):
- Add anf/ module with contract/plan/execute 3-layer separation
- AnfDiagnosticTag, AnfOutOfScopeReason, AnfPlan enums
- Stub execute_box (always returns Ok(None))
- 11 unit tests pass
Phase 145 P1 (Minimal success):
- String.length() whitelist implementation
- BinaryOp + MethodCall pattern: x + s.length() → t = s.length(); result = x + t
- Exit code 12 verification (VM + LLVM EXE)
- 17 unit tests pass
Phase 145 P2 (Generalization):
- Recursive ANF for compound expressions
- Left-to-right, depth-first evaluation order
- Patterns: x + s.length() + z, s1.length() + s2.length()
- ANF strict mode (HAKO_ANF_STRICT=1)
- Diagnostic tags (joinir/anf/*)
- 21 unit tests pass, 0 regression
Also includes Phase 143 P2 (else symmetry) completion.

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 |

feat(normalization): Phase 142 P0 - Statement-level normalization
...
## Summary
Changed normalization unit from "block suffix" to "statement (loop only)"
to prevent pattern explosion.
## Changes
1. **PlanBox** (`plan_box.rs`):
- Always return `loop_only()` for any `loop(true)`, regardless of what follows
- Subsequent statements (return, assignments) handled by normal MIR lowering
- ~70 lines reduced, 7 unit tests updated
2. **build_block** (`stmts.rs`):
- Removed `break` after consumed=1 from suffix_router
- Continue processing subsequent statements normally
- Phase 142 P0 comments added
3. **Tests**:
- Fixture: `phase142_loop_stmt_only_then_return_length_min.hako`
- VM smoke: exit code 3 (s="abc" → s.length() → 3)
## Results
- ✅ Unit tests: 10/10 passed
- ✅ Phase 142 VM smoke: PASS
- ✅ Phase 131 regression: PASS
- ✅ Build: Success
## Design
- **Pattern Explosion Prevention**: Normalize only the loop (consumed=1)
- **Out-of-Scope Policy**: Always Ok(None) for fallback
- **Fail-Fast**: Only for "in-scope but broken" cases

feat(normalized): Phase 141 P1.5 - external env inputs + KnownIntrinsic SSOT
...
## Task B: External env input bug fix (Priority 1)
Fix: Suffix normalization couldn't access prefix-built local variables
**Problem**: `s.length()` failed because 's' (from prefix `s = "abc"`) was
not in available_inputs during suffix normalization.
**Root cause**: `AvailableInputsCollectorBox::collect()` only collected
function params and CapturedEnv, missing `builder.variable_map`.
**Solution**: Add `prefix_variables` parameter with 3-source merge:
1. Function params (highest priority)
2. Prefix variables (medium priority - NEW)
3. CapturedEnv (lowest priority)
**Changed files**:
- src/mir/control_tree/normalized_shadow/available_inputs_collector.rs
- src/mir/builder/control_flow/normalization/execute_box.rs
- src/mir/builder/control_flow/joinir/patterns/policies/normalized_shadow_suffix_router_box.rs
- src/mir/builder/control_flow/joinir/routing.rs
- src/mir/builder/stmts.rs
- src/mir/control_tree/normalized_shadow/dev_pipeline.rs
- docs/development/current/main/design/normalized-expr-lowering.md (Available Inputs SSOT section)
**Tests**: 3 new unit tests (prefix merge, priority order)
## Task A: KnownIntrinsic SSOT化 (Priority 2)
Eliminate string literal scattered matching by centralizing to registry.
**Problem**: Adding new intrinsics required editing if/match chains with
hard-coded string literals (`if method == KnownIntrinsic::Length0.method_name()`).
**Solution**: Create `KnownIntrinsicRegistryBox` as SSOT:
- `lookup(method, arity) -> Option<KnownIntrinsic>`
- `get_spec(intrinsic) -> KnownIntrinsicSpec`
- Adding new intrinsics now requires: (1) enum variant, (2) registry entry only
**Changed files**:
- src/mir/control_tree/normalized_shadow/common/known_intrinsics.rs (NEW)
- src/mir/control_tree/normalized_shadow/common/expr_lowerer_box.rs
- src/mir/control_tree/normalized_shadow/common/expr_lowering_contract.rs (deprecated methods removed)
- src/mir/control_tree/normalized_shadow/common/mod.rs
- docs/development/current/main/design/normalized-expr-lowering.md (Known Intrinsic SSOT section)
**Impact**: ~30% code reduction in intrinsic matching logic
## Task C: Better diagnostics (Priority 3)
Add `OutOfScopeReason::IntrinsicNotWhitelisted` for precise diagnostics.
**Changed files**:
- src/mir/control_tree/normalized_shadow/common/expr_lowering_contract.rs (enum variant)
- src/mir/control_tree/normalized_shadow/common/expr_lowerer_box.rs (diagnostic logic)

fix(normalization): Tighten loop(true) gate to prevent loop(i<n) mismatch
...
Problem:
- Phase 97 LLVM EXE tests (next_non_ws, json_loader_escape) were failing
- NormalizationPlan accepted loop(i < n) but couldn't lower it
- Execute stage returned hard error instead of fallback
Root Cause:
- Plan stage only checked `ASTNode::Loop`, not condition
- loop(i < n) got Plan → Execute tried to normalize → error
- Should: loop(i < n) returns Ok(None) → fallback to Pattern2
Fix:
- Tighten gate in plan_box.rs (lines 50-71)
- Only accept loop(true) - literal Bool true
- loop(i < n) now returns Ok(None) → clean fallback
Added:
- Test: test_plan_block_suffix_no_match_loop_not_true()
- Verifies loop(i < n) returns None (not Plan)
Verification:
- Phase 97 next_non_ws LLVM EXE: PASS

refactor(normalization): Phase 135 P0 - Extend plan to zero post-loop assigns
...
Generalize NormalizationPlan suffix detection to accept zero post-loop assignments:
Goal: Improve entry point consistency by allowing `loop + assign* + return` (N >= 0)
Implementation:
- Modified plan_box.rs detection logic (only file changed)
- Removed `post_assign_count >= 1` requirement
- Unified Phase 131 (loop + return) and Phase 132-133 (loop + assign+ + return) paths
Changes:
- src/mir/builder/control_flow/normalization/plan_box.rs:
- Removed assignment count constraint
- Unified pattern detection: `loop + assign* + return` (N >= 0)
- apps/tests/phase135_loop_true_break_once_post_empty_return_min.hako (new fixture)
- tools/smokes/v2/profiles/integration/apps/phase135_*.sh (new smoke tests)
Pattern support:
- Phase 131/135: loop + return only (consumed: 2, post_assign_count: 0) ✅
- Phase 132: loop + 1 assign + return (consumed: 3, post_assign_count: 1) ✅
- Phase 133: loop + N assigns + return (consumed: 2+N, post_assign_count: N) ✅
Design principles maintained:
- **Minimal change**: Only plan_box.rs modified (execute_box unchanged)
- **SSOT**: Detection logic centralized in plan_box.rs
- **Box-First**: Responsibility separation preserved (Plan/Execute)
Test results:
- Unit tests (plan_box): 9/9 PASS (2 new tests added)
- Phase 135 VM/LLVM EXE: PASS (exit code 1)
- Phase 131 regression: 2/2 PASS (path now unified)
- Phase 133 regression: 2/2 PASS
- cargo test --lib: PASS
Benefits:
- Unified entry point for all loop + post patterns
- Easier maintenance (single detection logic)
- Future extensibility (easy to add new patterns)
- Clear separation of Phase 131 and Phase 132-135 paths
Default behavior unchanged: Dev-only guard maintained

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

feat(control_tree): Phase 132 P0 + P0.5 - loop(true) + post-loop support
...
**Phase 132 P0**: Extend loop(true) break-once to support post-loop statements
Goal: Support `loop(true) { x = 1; break }; x = x + 2; return x` → exit code 3
Implementation:
- loop_true_break_once.rs: Add post_k continuation generation
- Reuse Phase 130's lower_assign_stmt for post statements
- ExitMeta uses DirectValue mode (PHI-free)
**Phase 132 P0.5**: Fix StepTree post-loop statement visibility
Root cause: routing.rs created StepTree from Loop node only, losing post statements
Solution:
- New: normalized_shadow_suffix_router_box.rs
- Detects block suffix: Loop + Assign* + Return
- Creates StepTree from entire suffix (Block([Loop, Assign, Return]))
- Modified build_block() to call suffix router (dev-only)
Changes:
- apps/tests/phase132_loop_true_break_once_post_add_min.hako (new fixture)
- tools/smokes/v2/profiles/integration/apps/phase132_loop_true_break_once_post_add_*.sh

- src/mir/builder/control_flow/joinir/patterns/policies/normalized_shadow_suffix_router_box.rs (+380 lines)
- src/mir/builder/stmts.rs (build_block modified to support suffix skipping)
Design principles:
- StepTree unchanged: Block is SSOT for statement order
- No data duplication: Loop doesn't hold post_nodes
- Suffix router handles detection + conversion
- build_block() handles wiring only
