@@ -13,6 +13,23 @@ What Changed (today)
 - CLI `--using` を追加（`--using "ns as Alias"` / `--using '"apps/foo.nyash" as Foo'`）。
 - フィールドは box 先頭のみルールのリンタを Runner に追加（`NYASH_FIELDS_TOP_STRICT=1` でエラー）。
 - Syntax Torture スイートの実行正規化（末行比較）。一部テスト本文を Nyash 仕様に合わせて修正。
+- JSON v0 仕様に Stage‑3 ノード（Break/Continue/Throw/Try）を追記。Parser Stage‑3 設計メモの現状/残課題を更新。
+- LLVM smoke に Stage‑3 loop サンプル（break/continue + throw/try/catch/finally 付き）を追加（`NYASH_LLVM_STAGE3_SMOKE=1`）。
+- Bridge (`json_v0`) に Stage‑3 throw/try の実稼働ルートを追加（`NYASH_BRIDGE_THROW_ENABLE=1` / `NYASH_BRIDGE_TRY_ENABLE=1` で MIR Throw/Catch を生成）。
+
+Decision (Phase‑15 wrap‑up)
+- MIR13 移行（PHI 非生成）: Phase‑15 の締めとして、MIR 生成層（Bridge/Builder）は PHI を生成しない方針に切替。PHI 合成は LLVM 層（llvmlite/Resolver）に集約。
+- LoopForm は次フェーズ（MIR18）で導入: まずは MIR14 を維持し、次フェーズで `LoopHeader/Enter/Latch` 等の占位命令を追加。現行 Phase‑15 は CFG パターン検知でループ搬送値を合成。
+- 例外は段階導入: Throw/Catch は現行維持（Bridge ゲートで出力可）。Try/Finally の構造化は将来の TryRegion で検討。
+
+Next Focus (Throw/Try — LLVM first)
+- ブリッジ設計: `emit_degraded_throw` の差し替え方針を策定し、JSON v0 `Try` ノード → MIR 変換の仕様を決める（Stage-3 例外モデル）。
+- MIR Builder/Runtime 調査: Rust VM/PyVM の `ControlFlow::Throw` 経路と既存 TryCatch 降格の挙動を整理。必要に応じて docs と CURRENT_TASK に反映。
+- PyVM 設計: 例外モデルをどこまで Python 側に実装するか決め、最小テスト計画を用意。
+- LLVM 実装方針: Throw/Try の MIR 命令を LLVM 側がどう扱うか（panic扱い or fallback）を設計し、smoke 更新案を作る。
+- テスト計画: JSON フィクスチャと `tools/llvm_smoke.sh` を中心に Stage-3 例外用のスモーク/単体テストを整備。
+
+※ Cranelift/JIT 系は当面対象外。ビルド時も LLVM のみを有効化（JIT 関連 feature/CI は無視）。

+Smoke Policy (Phase‑15)
+- PyVM: 一部チェックのみ（async/nowait/await/GC/sync は対象外）
+- LLVM: フル対応（llvmlite harness）。`tools/smokes/curated_llvm.sh [--phi-off]` を利用
+- JIT: 未整備（JIT向けスモークは `tools/smokes/archive/` に移管）
+
+MIR13 Plan（Phase‑15 終盤）
+- Bridge/Builder: PHI を生成しない（受理は維持）。If/Loop の合流は LLVM Resolver に任せる。
+- llvmlite: Resolver を使い、BB 先頭で PHI 合成。ループは preheader/cond/body の CFG から搬送値を復元（break は exit 側でマージ）。
+- Smoke: LLVM はまず loop‑only（break/continue）を常時緑化。例外系（throw/try）は IR 降ろし込み整備後に復帰。
+- 詳細設計: `docs/private/papers/paper-e-loop-signal-ir/mir-evolution-plan.md` に MIR14→MIR13→MIR17 の段階的移行計画を記載。

 Array/Map Literals Plan（Syntax Sugar）
 - Stage‑1: Array literal `[e1, e2, ...]` を実装（ゲート: `NYASH_SYNTAX_SUGAR_LEVEL=basic|full` または `NYASH_ENABLE_ARRAY_LITERAL=1`）。
   - Lowering: `new ArrayBox()` → 各要素を評価 → `.push(elem)` を左から右に順に発行 → 最後に配列値を返す。

+# MIR進化計画: MIR14 → MIR13 → MIR17
+
+## 概要
+
+LoopForm導入に向けた段階的なMIR進化戦略。PHI命令の責務をLLVM層に移管し、より高レベルな制御構造表現を導入する。
+
+## 命令数の変遷
+
+```
+MIR14（現在）: 14命令（PHIあり）
+    ↓ Phase 15終盤
+MIR13: 13命令（PHI除去）
+    ↓ Phase 16
+MIR17: 17命令（LoopForm追加）
+```
+
+## MIR13（Phase 15終盤）
+
+### 削除される命令
+- **Phi**: SSA PHIノードの生成をLLVM層に移管
+
+### 残る13命令
+1. Const
+2. Load / Store
+3. UnaryOp / BinOp / Compare / TypeOp
+4. Branch / Jump / Return
+5. NewBox / BoxCall
+6. ExternCall / Call
+7. Throw / Catch（既存維持）
+
+### 実装方針
+- Bridge/BuilderはPHIを生成しない
+- LLVM層（llvmlite/Resolver）がCFGパターンからPHIを合成
+- VM/Interpreterは直線的実行を継続（PHI無視）
+
+## MIR17（Phase 16）
+
+### 追加される4命令（LoopForm）
+
+1. **LoopHeader** `{ id, params[] }`
+   - ループヘッダBBの宣言
+   - params[]はループ搬送値のプレースホルダ
+
+2. **LoopEnter** `{ header: bb, args[] }` (terminator)
+   - Preheaderからヘッダへの遷移
+   - args[]は搬送値の初期値
+
+3. **LoopLatch** `{ header: bb, args[] }` (terminator)
+   - 本体末尾からヘッダへのバックエッジ
+   - args[]は更新後の搬送値
+
+4. **LoopExit** `{ exit: bb }` (terminator)
+   - ループからの脱出（break相当）
+
+### なぜ+4命令か
+- ループの構造を明示的に表現
+- Preheader/Header/Body/Exitの役割を宣言的に
+- LLVM層でのPHI生成が機械的に可能
+
+## 合流点の扱い（将来検討）
+
+### MergeForm（追加候補）
+```rust
+// If/Else等の合流用（将来のMIR18以降）
+MergeHeader { id, params[] }
+MergeEnter { header: bb, args[] }
+```
+
+## 移行のメリット
+
+1. **責務分離の明確化**
+   - MIR: 制御構造の宣言
+   - LLVM: SSA表現の生成
+
+2. **段階的移行**
+   - Phase 15: PHI生成を止める（互換性維持）
+   - Phase 16: LoopForm導入（新機能）
+
+3. **将来拡張への道筋**
+   - Generator/Async/Effectへの対応準備
+   - LifeBox Model（LBM）への布石
+
+## AI協働の記録（2025-09-16）
+
+### Codex提案
+- PHI合成をllvmlite側で実施
+- LoopForm/MergeFormの構造化表現
+- TryRegionによる例外構造化（将来）
+
+### 人間の洞察
+- 「MIR13に減らしてから+4でMIR17」
+- 段階的移行の重要性
+- 一気に変えないことの価値
+
+### 合意形成
+- Phase 15でまずPHI非生成化
+- 安定後にLoopForm導入
+- 責務分離を徹底
+

@@ -13,6 +13,37 @@ Guiding Principles
 - Short-circuit semantics are already mirrored via logical nodes; Stage-3 should reuse the same block-building infrastructure (Bridge/VM/JIT) to avoid special cases.
 - Continue the "degrade to expression" approach when code generation is not ready (e.g. throw/try) so that Stage-2 tests stay green while the full implementation is developed.
 
+Current Status (Phase 15.3 – 2025-09-16)
+- ParserBox / Selfhost compiler expose `stage3_enable` and `--stage3` CLI flag, defaulting to the safe Stage-2 surface.
+- Break/Continue JSON emission and Bridge lowering are implemented. Bridge now emits `Jump` to loop exit/head and records instrumentation events.
+- Throw/Try nodes are emitted when the gate is on, but still degrade to expression/no-op during lowering; runtime semantics remain TBD.
+- Documentation for JSON v0 (Stage-3 nodes) is updated; remaining runtime work is tracked in CURRENT_TASK.md.
+
+Runtime snapshot
+- MIR Builder already lowers `ASTNode::Throw` into `MirInstruction::Throw` (unless disabled via `NYASH_BUILDER_DISABLE_THROW`) and has a provisional `build_try_catch_statement` that emits `Catch`/`Jump` scaffolding with env flags controlling fallback.
+- Rust VM (`interpreter::ControlFlow::Throw`) supports catch/finally semantics and rethrows unhandled exceptions.
+- Bridge degradation prevents these MIR paths from activating unless `NYASH_BRIDGE_THROW_ENABLE=1`;既定では Const0 を出し、フラグONで実際に `Throw` を生成する。
+
+PyVM plan
+- Current PyVM runner treats Stage-3 constructs as no-ops because JSON v0 never emits MIR throws; once Bridge emits them, PyVM must mirror Rust VM semantics:
+  - Introduce a lightweight `exception` representation (reuse ErrorBox JSON form) and propagate via structured returns.
+  - Implement try/catch/finally execution order identical to Rust VM (catch matches first, finally always runs, rethrow on miss).
+  - Add minimal smoke tests under `tools/pyvm_stage2_smoke.sh` (gated) to ensure PyVM and LLVM stay in sync when Stage-3 is enabled.
+
+LLVM plan
+- Short term: continue degrading throw/try to keep LLVM pipeline green while implementation lands (Stage-3 smoke ensures awareness).
+- Implementation steps once runtime semantics are ready:
+  1. Ensure MIR output contains `Throw`/`Catch` instructions; update LLVM codegen to treat `Throw` as a call to a runtime helper (`nyash.rt.throw`) that unwinds or aborts.
+  2. Model catch/finally blocks using landing pads or structured IR (likely via `invoke`/`landingpad` in LLVM); document minimal ABI expected from NyRT.
+  3. Add gated smoke (`NYASH_LLVM_STAGE3_SMOKE`) that expects non-degraded behaviour (distinct exit codes or printed markers) once helper is active.
+- Until landing pad support exists, document that Stage-3 throw/try is unsupported in LLVM release mode and falls back to interpreter/PyVM.
+
+Testing plan
+- JSON fixtures: create `tests/json_v0_stage3/{break_continue,throw_basic,try_catch_finally}.json` to lock parser/bridge output and allow regression diffs.
+- PyVM/VM: extend Stage-3 smoke scripts with throw/try cases (under gate) to ensure runtime consistency before enabling by default.
+- LLVM: `NYASH_LLVM_STAGE3_SMOKE=1` は `NYASH_BRIDGE_THROW_ENABLE=1` / `NYASH_BRIDGE_TRY_ENABLE=1` と組み合わせて実際の例外経路を確認。将来的に常時ONへ移行予定。
+- CI gating: add optional job that runs Stage-3 smokes (PyVM + LLVM) nightly to guard against regressions while feature is still experimental.

+- Async (LLVM only):
+  - `apps/tests/async-await-min/main.nyash`
+  - `apps/tests/async-spawn-instance/main.nyash`
+  - `apps/tests/async-await-timeout-fixed/main.nyash` (set `NYASH_AWAIT_MAX_MS=100`)
+
+Runner Scripts
+- `tools/smokes/curated_llvm.sh [--phi-off]`
+  - `--phi-off`: enables `NYASH_MIR_NO_PHI=1` + verifier relaxor.
+- Archived (not maintained): see `tools/smokes/archive/`
+  - `smoke_phase_10_10.sh`, `smoke_vm_jit.sh`, `smoke_async_spawn.sh`, `jit_smoke.sh`, `aot_smoke_cranelift.sh`
+  - These target JIT/Cranelift-era flows. Use the curated LLVM runner instead.
+
+Flags
+- `NYASH_LLVM_USE_HARNESS=1`: use llvmlite harness for AOT.
+- `NYASH_MIR_NO_PHI=1` and `NYASH_VERIFY_ALLOW_NO_PHI=1`: PHI-less MIR (edge-copy) mode.
+
+Notes
+- Marked async smokes should not be run under PyVM/JIT.
+- Legacy/archived smokes may exist; curated runner avoids them.
