feat(control_tree): Phase 133 P0 - Multiple post-loop assigns support

Browse Source 
Extend Phase 132's loop(true) + post-loop to accept multiple assignments:

Goal: `x=0; loop(true){ x=1; break }; x=x+2; x=x+3; return x` → exit code 6

Implementation:
- Extended loop_true_break_once.rs pattern detection (len() == 2 → len() >= 2)
- Added iterative assignment lowering (for loop over post_nodes)
- Reused Phase 130's lower_assign_stmt for each assignment
- Maintained ExitMeta DirectValue mode (PHI-free)

Changes:
- apps/tests/phase133_loop_true_break_once_post_multi_add_min.hako (new fixture)
- tools/smokes/v2/profiles/integration/apps/phase133_*_multi_add_*.sh (new smokes)
- src/mir/control_tree/normalized_shadow/loop_true_break_once.rs (+30 lines)
- docs/development/current/main/phases/phase-133/README.md (new documentation)
- docs/development/current/main/10-Now.md (Phase 133 entry added)

Scope (Phase 130 baseline):
- ✅ x = <int literal>
- ✅ x = y (variable copy)
- ✅ x = x + <int literal> (increment)
- ❌ Function calls / general expressions (future phases)

Design principles:
- Minimal change: ~30 lines added
- SSOT preservation: env_post_k remains single source of truth
- Reuse: Leveraged existing lower_assign_stmt
- Fail-Fast: Contract violations trigger freeze_with_hint

Test results:
- cargo test --lib: 1176 PASS
- Phase 133 VM: PASS (exit code 6)
- Phase 133 LLVM EXE: PASS (exit code 6)
- Phase 132 regression: PASS (exit code 3)
- Phase 131 regression: PASS (exit code 1)
- Phase 97 regression: PASS

Architecture maintained:
- 5-function structure unchanged (main/loop_step/loop_body/k_exit/post_k)
- PHI-free DirectValue mode
- Zero changes to ExitMeta, merge logic, or JoinIR contracts

**Phase 133: loop(true) break-once + multiple post-loop assigns（dev-only）**
- 目的: Phase 132 を拡張し、post-loop で複数の assign を受理（PHI-free 維持）
- 仕様:
- `loop(true) { x = 1; break }; x = x + 2; x = x + 3; return x` は exit code `6`（VM/LLVM EXE parity）

- Pattern detection: all_assigns + ends_with_return
- Post-loop lowering: for loop で複数 assign 処理
- SSOT: env_post_k が最終値を保持（ExitMeta に反映）
- Fixture: `apps/tests/phase133_loop_true_break_once_post_multi_add_min.hako`（期待: 6）
- Smoke:
- `phase133_loop_true_break_once_post_multi_add_vm.sh` PASS

# Phase 133: Promoted Carrier Join ID (Loop Condition Promotion)
# Phase 133: loop(true) break-once Multiple Post-Loop Assignments
**Date**: 2025-12-15
**Status**: ✅ Done (P1 fix complete)
**Scope**: Loop内のcondition promotionにおいて、Trim promoted carrierにjoin_idが割り当てられていない問題を解決
**Status**: ✅ Implemented & Verified
**Date**: 2025-12-18
**Scope**: P0 (Minimal)
---
## Overview
## 背景
Phase 133-P0 extends Phase 132-P4's loop(true) break-once pattern to accept **multiple post-loop assignments** before the final return statement. This enables more complex post-loop computation while maintaining the PHI-free Normalized shadow architecture.
実アプリ由来のループパターン（JsonParserBox._skip_whitespace）から発見：
## Pattern
```nyash
loop(index < s.length()) {
local char = s.substring(index, index + 1)
if char == " " { // ← promoted carrier が生成される
count = count + 1
index = index + 1
x = 0 // pre-loop init
loop(true) { // condition is Bool literal true
x = 1 // body assignment
break // break at end
}
x = x + 2 // first post-loop assignment
x = x + 3 // second post-loop assignment (NEW in P133)
return x // return updated value (1 + 2 + 3 = 6)
```
## Implementation Changes
### 1. Pattern Detection (loop_true_break_once.rs)
**Extended from Phase 132**:
- Phase 132: `post_nodes == [Assign, Return]` (exactly 1 assign)
- Phase 133: `post_nodes == [Assign+, Return]` (1+ assigns)
```rust
// Phase 133-P0: Detect multi-assign + return pattern (generalize Phase 132-P4)
let has_post_computation = if post_nodes.is_empty() {
false
} else if post_nodes.len() >= 2 {
// Check if all nodes except the last are Assign statements
let all_assigns = post_nodes[..post_nodes.len() - 1]
.iter()
.all(|n| matches!(n, StepNode::Stmt { kind: StepStmtKind::Assign { .. }, .. }));
// Check if the last node is a Return statement
let ends_with_return = matches!(
post_nodes.last(),
Some(StepNode::Stmt { kind: StepStmtKind::Return { .. }, .. })
);
all_assigns && ends_with_return
} else {
break // ← break時の join_id が未割り当て
false
};
```
### 2. Post-Loop Lowering (loop_true_break_once.rs)
**Iterative Assignment Processing**:
```rust
// Phase 133-P0: Lower multiple post-loop assignments
// Split post_nodes into assigns and return (last element is return)
let assign_nodes = &post_nodes[..post_nodes.len() - 1];
let return_node = post_nodes.last().unwrap();
// Lower all assignment statements
for node in assign_nodes {
let StepNode::Stmt { kind: StepStmtKind::Assign { target, value_ast }, .. } = node else {
return Ok(None);
};
if LegacyLowerer::lower_assign_stmt(
target,
value_ast,
&mut post_k_func.body,
&mut next_value_id,
&mut env_post_k,
)
.is_err()
{
return Ok(None);
}
}
```
**エラー（修正前）**: `[phase229] promoted carrier 'is_char_match' has no join_id`
### 3. SSOT Maintenance
---
**ExitMeta Contract**:
- **Unchanged**: ExitMeta still uses `env_post_k`'s final values as SSOT
- **Iterative Updates**: Each assignment updates `env_post_k` map
- **Final State**: Last assignment's result becomes the exit value
## 根本原因
## JoinIR Structure (Unchanged from Phase 132)
- Trim系のcondition promotion (A-3) が返す `CarrierInfo` は promoted carrier を `carriers` に入れず `loop_var_name` 側に置く設計
- Pattern2 が `find_carrier()` で join_id を取ろうとして `[phase229] ... has no join_id` で落ちる
- 該当: `src/mir/loop_pattern_detection/loop_body_carrier_promoter.rs:73` (コメント通り "carriers: Empty")
**5-Function Module**:
1. `main(env)` → TailCall(loop_step, env)
2. `loop_step(env)` → TailCall(loop_body, env)
3. `loop_body(env)` → <assign statements> → TailCall(k_exit, env)
4. `k_exit(env)` → TailCall(post_k, env)
5. `post_k(env)` → **<assign>*** → Ret(env[x]) ← **NEW: Multiple assigns**
---
**Contract**:
- PHI-free: All state passing via env arguments + continuations
- DirectValue mode: ExitMeta uses post_k's final env values
## 修正内容（P1: 箱理論アプローチ）
## Scope Limitations (Phase 130 Baseline)
**方針**: Pattern2 は Trim(A-3) を自前で join_id 解決しない。Trim は既に `apply_trim_and_normalize()` (= TrimLoopLowerer) が SSOT で ConditionEnv に join_id を登録するので、そちらに責務を寄せて二重実装を消す。
**Allowed Assignments**:
- ✅ `x = <int literal>` (e.g., `x = 0`)
- ✅ `x = y` (variable copy)
- ✅ `x = x + <int literal>` (increment)
**実装**: `src/mir/builder/control_flow/joinir/patterns/pattern2_with_break.rs`
- `promote_and_prepare_carriers()` で Promoted が Trim 由来かチェック (`carrier_info.trim_helper().is_some()`)
- Trim の場合:
- `promoted_pairs.push()` をスキップ
- `DigitPosConditionNormalizer::normalize()` をスキップ
- `[phase229]` の promoted_pairs 解決ループ自体を通らない
- Trim でない（DigitPos等）なら、現状の promoted_pairs + join_id 解決を維持
**Not Allowed**:
- ❌ `x = call(...)` (function calls)
- ❌ `x = a + b` (general binary ops)
- ❌ `if`, `loop`, `print` in post-loop
**結果**: "Trim を cond_promoter 側で promote したのに、Pattern2 側で join_id を要求して死ぬ" 構造矛盾が解消
## Test Coverage
---
### Fixture
- `apps/tests/phase133_loop_true_break_once_post_multi_add_min.hako`
- Expected exit code: **6** (1 + 2 + 3)
## 検証
### Smoke Tests
1. **VM**: `tools/smokes/v2/profiles/integration/apps/phase133_loop_true_break_once_post_multi_add_vm.sh`
2. **LLVM EXE**: `tools/smokes/v2/profiles/integration/apps/phase133_loop_true_break_once_post_multi_add_llvm_exe.sh`
### P0: Fixture & Smoke Test 実装
- ✅ Fixture: `apps/tests/phase133_json_skip_whitespace_min.hako`
- ✅ Smoke: `tools/smokes/v2/profiles/integration/apps/phase133_json_skip_whitespace_llvm_exe.sh`
- 現状: compile-only（`--dump-mir`）で `[phase229] ... has no join_id` が出ないことを固定
### Regression Tests

- ✅ Phase 131 (exit code 1)
- ✅ Phase 97 (numeric output 2, -1, 3)
### P1: 修正完了
- ✅ MIR compilation: promoted carrier join_id エラーが消滅

# Result: PASS (numeric output)
```
## Design Principles
### 1. Minimal Change
- Extends Phase 132's detection logic from `len() == 2` to `len() >= 2`
- Replaces single assignment lowering with iterative loop
- **Zero changes** to JoinIR structure, ExitMeta, or merge logic
### 2. SSOT Preservation
- `env_post_k` remains the single source of truth for exit values
- Each assignment updates `env_post_k` map in order
- ExitMeta collection happens **after** all assignments
### 3. Reuse
- Uses `LegacyLowerer::lower_assign_stmt` for each assignment
- Leverages Phase 130's proven assignment handling
- No new lowering code required
### 4. Fail-Fast
- Contract violations trigger `freeze_with_hint` in strict mode
- Missing env fields → explicit error with hint
- Invalid assignment → fallback to legacy (Ok(None))
## Dev Toggle
**Required**: `NYASH_JOINIR_DEV=1` and `HAKO_JOINIR_STRICT=1`
This is a dev-only Normalized shadow feature. With toggle OFF, the pattern falls back to legacy lowering with zero impact on production code.
## Files Modified
1. `src/mir/control_tree/normalized_shadow/loop_true_break_once.rs` (3 edits)
- Extended pattern detection
- Iterative assignment lowering
- Updated debug logging
2. `apps/tests/phase133_loop_true_break_once_post_multi_add_min.hako` (new)
3. `tools/smokes/v2/profiles/integration/apps/phase133_loop_true_break_once_post_multi_add_vm.sh` (new)
4. `tools/smokes/v2/profiles/integration/apps/phase133_loop_true_break_once_post_multi_add_llvm_exe.sh` (new)
## Acceptance Criteria
- ✅ cargo test --lib PASS (1176 tests)
- ✅ Phase 133 VM smoke: PASS (exit code 6)
- ✅ Phase 133 LLVM EXE smoke: PASS (exit code 6)
- ✅ Phase 132 regression: PASS (exit code 3)
- ✅ Phase 131 regression: PASS (exit code 1)
- ✅ Phase 97 regression: PASS (numeric output)
- ✅ Dev toggle OFF: Zero impact on production
## Summary
Phase 133-P0 successfully generalizes Phase 132-P4's single post-loop assignment to support **multiple post-loop assignments**, enabling more complex post-loop computation patterns. The implementation maintains all architectural invariants (PHI-free, DirectValue mode, SSOT) while adding only ~30 lines of code.
**Key Achievement**: Transformed fixed-length pattern detection (`len() == 2`) to flexible pattern detection (`len() >= 2`) with zero impact on existing contracts.
