refactor(edgecfg): add Frag/ExitKind API entrypoint (Phase 264 design-first)
...
Phase 264 P0: EdgeCFG Fragment 入口API作成（実装置換なし）
- 入口フォルダ作成: src/mir/builder/control_flow/edgecfg/api/
- コア型定義: ExitKind, EdgeStub, Frag
- 合成関数シグネチャ: seq, if_, loop_, cleanup（中身TODO、pub(crate)）
- 最小テスト: 3個のユニットテスト追加（frag.rs）
- ドキュメント連動: edgecfg-fragments.md に実装入口追記
制約遵守:
- 既存 pattern6/7/8 未改変
- merge/EdgeCFG 未改変
- 既存LoopId使用（control_form.rs に PartialOrd, Ord 追加）
- MIR側EdgeArgs使用（JoinIRと混線回避）
- BTreeMap採用（決定的順序保証、Phase 69-3 教訓）
次フェーズ: Phase 265 で Pattern8 適用時に compose::loop_ を実装

fix(joinir): improve Pattern3 classification to exclude simple conditional assignment (Phase 264 P0)
...
Problem:
- Pattern3 heuristic was too conservative: detect_if_in_body() returned
true for ANY if statement, causing simple conditional assignments to be
misclassified as Pattern3IfPhi
- Example: `if i == 0 then seg = "first" else seg = "other"` was routed
to Pattern3, but Pattern3 only handles if-sum patterns like
`sum = sum + (if x then 1 else 0)`
- This caused loops with conditional assignment to fail Pattern3 check
and exhaust all routing paths
Solution (Conservative, Phase 264 P0):
- ast_feature_extractor.rs:
- detect_if_else_phi_in_body(): Always return false
- has_if = has_if_else_phi (don't use detect_if_in_body())
- loop_pattern_detection/mod.rs:
- Add has_if_sum_signature() (returns false for P0)
- has_if_else_phi = carrier_count > 1 && has_if_sum_signature(scope)
Effect:
- Simple conditional assignment loops now fall through to Pattern1 ✅
- Pattern3 misrouting prevented ✅
Results:
- Lib tests: 1368/1368 PASS (no regression)
- Minimal repro: phase264_p0_bundle_resolver_loop_min.hako PASS ✅
- Quick smoke: 45/46 (unchanged - complex BundleResolver loop needs P1)
Phase 264 P1 TODO:
- Implement accurate if-sum signature detection (AST/CFG analysis)
- Support complex nested loops in Pattern2 or new pattern

...
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）

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
- CFG-based entry predecessor computation (header_preds - latch)
- Multi-entry-pred support (bb0 host + bb10 JoinIR main)
- Explicit host_entry_block addition (emit_jump runs after finalize)
P1.3: Smoke script validation

✅ phase257_p0_last_index_of_min.hako verify
✅ ./tools/smokes/v2/run.sh --profile quick (no Pattern6 false positive)
Technical discovery:
- Host entry block (bb0) Jump set in Phase 6 (after finalize)
- instruction_rewriter bypasses set_terminator(), skips successor update

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
Files modified:
- src/mir/builder/control_flow/joinir/patterns/pattern6_scan_with_init.rs
- src/mir/join_ir/lowering/scan_with_init_reverse.rs (new)

Known issue (pre-existing):
- PHI predecessor mismatch bug exists in Pattern6 (both forward and reverse)
- This bug existed BEFORE Phase 257 P0 implementation

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/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 146/147 - Loop/If Condition ANF with Compare support
...
## Phase 146 P0: ANF Routing SSOT Unified
**Goal**: Unify ANF routing in `lower_expr_with_scope()` L54-84, remove legacy lowering
**Changes**:
- expr_lowerer_box.rs: Added scope check (PureOnly → skip ANF, WithImpure → try ANF)
- post_if_post_k.rs: Removed legacy inline lowering (L271-285), added `lower_condition_legacy()` helper
- contract.rs: Already had `CondLoweringFailed` out-of-scope reason
**Test Results**: ✅ Phase 146 P0 smoke (exit 7), 0 regressions
## Phase 146 P1: Compare Operator Support
**Goal**: Enable ANF for condition expressions with Compare operators
**Changes**:
- joinir_dev.rs: Added `anf_allow_pure_enabled()` (HAKO_ANF_ALLOW_PURE=1)
- expr_lowerer_box.rs: PureOnly scope ANF support (L56-66)
- execute_box.rs: Compare operator support (+122 lines)
- `execute_compare_hoist()`, `execute_compare_recursive()`, `ast_compare_to_joinir()`
- Extended `normalize_and_lower()` for Compare
**Test Results**: ✅ Phase 146 P1 smoke (exit 7 with flags), 0 regressions
## Phase 147 P0: Recursive Comparison ANF
**Goal**: Extend recursive ANF to Compare operators
**Changes**:
- contract.rs: Added `AnfParentKind::Compare` variant
- plan_box.rs: Compare case in BinaryOp routing (L68-79, L134-139)
- Distinguishes Compare vs arithmetic BinaryOp
**Benefits**: Enables recursive ANF for comparisons
- `s.length() == 3` → `t = s.length(); if (t == 3)` ✅
- `s1.length() < s2.length()` → `t1 = s1.length(); t2 = s2.length(); if (t1 < t2)` ✅

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(phase143/r0): Contract SSOT extraction - loop-if-exit pattern refactoring
...
Phase 143 R0: Refactor P0 to prevent if-branch explosion in P1/P2
**Key Changes**:
- New: loop_if_exit_contract.rs (LoopIfExitShape, LoopIfExitThen, OutOfScopeReason)
- Contract SSOT for pattern shape detection and exit action discrimination
- Separated unit tests to tests/phase143_loop_if_exit_contract.rs (8 tests)
- Removed embedded tests from implementation file
- Updated module declarations for contract and test modules
**Benefits**:
- Enum-driven pattern discrimination (no if-branch explosion)
- P1 extension: Add Continue via 1 enum variant + 1 match arm
- P2 extension: Add else via contract fields (linear growth, not exponential)
- Improved maintainability and code discoverability
**Verification**:
- cargo check: ✅ 0 errors
- Unit tests: ✅ 8/8 passed
- Documentation: ✅ Updated 10-Now.md and 30-Backlog.md

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)

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

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

docs: Phase 131 P0 structure implementation complete
...
Document Phase 131 P0 Normalized loop(true) break-once:
**Documentation**:
- docs/development/current/main/phases/phase-131/README.md (234 lines)
- Goal: loop(true) { <assign>* ; break } in Normalized (PHI-free)
- Scope: one-time execution loop only
- Contract: Bool(true) literal + break at end
- SSOT: EnvLayout, loop structure contract, VM+LLVM parity
- Current status: structure implemented, execution wiring pending
- docs/development/current/main/10-Now.md
- Updated Next section with Phase 131 P0 status
**Deliverables** (P0):
- ✅ Complete loop(true) break-once Normalized lowering logic
- ✅ PHI-free implementation (env + continuations)
- ✅ Box-First modular design
- ✅ Foundation for execution (structure verified)
- ✅ Unit tests passing (1155/1155)
**Known Limitation**:
- Execution path not yet wired (dev-only observation mode)
- Follow-up phase needed to route execution through Normalized shadow
- VM/LLVM smokes fail (expected until execution wiring)
**Next Steps**:
1. Modify try_cf_loop_joinir to check Normalized shadow first
2. Add dev-mode routing for loop(true) break-once
3. Implement JoinModule → MIR merge for loop patterns
4. Enable VM/LLVM smoke tests
