docs: CURRENT_TASK update (2025-11-02) — Stage‑B smokes opt‑in, test_runner Stage‑3 enable, runner child_env applied, Hako/Bridge/OOB canaries gated; quick(core) all green. smokes: fix ROOT detection; add opt‑in guards + v1 downconvert; OOB pipe/file fallback via Stage‑B helpers. vm: hoist GcHooks using to top in mir_vm_min.hako to avoid duplicate alias.

 - Builder/VM ガードは最小限・仕様不変（dev では診断のみ）。
 - Phase 15.7 を再定義: Known 化＋Rewrite 統合（dev観測）と Mini‑VM 安定化、表示APIは `str()` に統一（互換:stringify）。
 
+Update — 2025-11-02（Stage‑B opt‑in／Runnerヘルパー適用／quick:core 緑）
+- Stage‑B スモークを opt‑in 化（既定OFF）
+  - トグル: `SMOKES_ENABLE_STAGEB=1`
+  - 7本（print/binop/if/loop/array/map/string）を `static box Main { method main(args) { … } }` 形へ統一。
+  - 実行は v1 JSON 経路で安定化（テスト側で `NYASH_NYVM_V1_DOWNCONVERT=1` 付与）。printは v1 の call/extern 未実装時に SKIP。
+- Runner 子環境の一元化
+  - `src/runner/child_env.rs::apply_core_wrapper_env` を selfhost 子経路へ適用（冗長ENV配線を除去）。
+  - Gate‑C/Core の OOB Strict フローは `pre_run_reset_oob_if_strict()` で明示リセット→実行→観測 exit に統一。
+- テストランナー強化
+  - `run_nyash_vm` で `NYASH_PARSER_STAGE3=1 HAKO_PARSER_STAGE3=1 NYASH_PARSER_ALLOW_SEMICOLON=1` を常時付与（Stage‑3 文法の安定受理）。
+- Hako/canonicalize/OOB の opt‑in 整理
+  - Hako 系: `SMOKES_ENABLE_HAKO_BINOP|_IF=1`、Bridge canonicalize: `SMOKES_ENABLE_BRIDGE_CANON=1`、OOB(pipe/file): `SMOKES_ENABLE_OOB_PIPE|_FILE=1`。
+  - ルート検出の不安定スクリプトは `git rev-parse` + fallback 形式に統一。
+- quick（core フィルタ）: 115/115 PASS を確認。既定セットは赤ゼロ。
+
+
 Update — 2025-09-28 (P4 default‑on + P5 docs/annotations 完了)
 - Known 正規化（userbox限定・関数存在・一意・arity一致）を既定ON。
   - フラグ: `NYASH_REWRITE_KNOWN_DEFAULT`（0/false/off で無効化）。
