Analyzer安定化完了: NYASH_DISABLE_PLUGINS=1復元 + plugin無効化根治

## 修正内容
1. **hako_check.sh/run_tests.sh**: NYASH_DISABLE_PLUGINS=1 + NYASH_BOX_FACTORY_POLICY=builtin_first追加
2. **src/box_factory/plugin.rs**: NYASH_DISABLE_PLUGINS=1チェック追加
3. **src/box_factory/mod.rs**: plugin shortcut pathでNYASH_DISABLE_PLUGINS尊重
4. **tools/hako_check/render/graphviz.hako**: smart quotes修正（parse error解消）

## 根本原因
- NYASH_USE_PLUGIN_BUILTINS=1が自動設定され、ArrayBox/MapBoxがplugin経由で生成を試行
- bid/registry.rsで"Plugin loading temporarily disabled"の状態でも試行されエラー
- mod.rs:272のshortcut pathがNYASH_DISABLE_PLUGINSを無視していた

## テスト結果
- 10/11 PASS（HC011,13-18,21-22,31）
- HC012: 既存issue（JSON安定化未完）

+Checklist — Ring1/Plugins polish（このフェーズで完了）
+- [ ] Env 統一（二重解消）: `NYASH_FILEBOX_MODE`/`NYASH_DISABLE_PLUGINS` に一本化し、
+      旧 `NYASH_USE_PLUGIN_BUILTINS` / `NYASH_PLUGIN_OVERRIDE_TYPES` は非推奨（互換ブリッジは維持）
+- [ ] 初期化順のSSOT: `register_builtin_filebox`（feature）→ dynamic登録（toml）→ provider選択→ FILEBOX_PROVIDER 設定（vm/vm_fallback 共通）
+- [ ] Provider 登録口の一本化: static/dynamic/builtin を同じ ProviderFactory 登録APIに集約（select は registry のみ）
+- [ ] FileBox 公開の一本化: `basic/file_box.rs` を再エクスポート/委譲化し、公開は BoxShim（委譲）に揃える（重複実装撤去）
+- [ ] Using/modules のSSOT確認: modules優先→相対ファイル推定→not found（警告; verboseで詳細）を維持
+- [ ] JSON_ONLY 監査: json-lsp時は stdout 純JSON・ログは stderr の規約を plugin_guard/loader を含む全経路で確認
+- [ ] AST/IR ゲート最終化: `_needs_ast`/`_needs_ir` の方針を docs と実装で一致させる（ASTは最小; 既定 no-ast）
+- [ ] Capability introspection: FILEBOX_PROVIDER の `caps(read/write)` を BoxShim から取得・Fail‑Fastの可否を明示
+- [ ] スモーク追加: core‑ro(open/read/close)/auto(フォールバック)/plugin-only(厳格)/analyzer(json-lsp純出力) の代表ケース
+- [ ] Docs 同期: FILEBOX_PROVIDER.md / ENV_VARS.md / hako_check README を最終状態に更新
+ - [ ] フォールバック保証: プラグインのロード失敗だけでなく「create_box 失敗時」にも ring1/core‑ro へ自動フォールバック（auto モード）。plugin‑only では Fail‑Fast。
+ - [ ] 失敗時スモーク: ArrayBox の plugin が存在するが creation に失敗するケースを再現し、ring1/core‑ro で生成できることを確認。
+
+Completed — FileBox Provider Wiring（C: Feature と静的/動的の選択を1本化）
+- 目的: File I/O を SSOT 抽象（FileIo）＋ 薄いラッパ（FileBoxShim）＋ provider_registry で一本化し、静的/動的/コアRO の選択を ENV で制御する。
+- 完了内容:
+  - provider_lock: `FILEBOX_PROVIDER` を追加し、グローバルに選択結果を保持
+  - vm 起動時に `read_filebox_mode_from_env` → `select_file_provider` で provider を決定・登録
+  - CoreRoFileIo を read‑only で実装（thread‑safe）
+  - FileBox を provider 経由の委譲へ寄せ、basic/file_box.rs は deprecate 化
+  - Cargo.toml に `builtin-filebox` feature を追加
+  - Docs/ENV を同期（FILEBOX_PROVIDER.md / ENV_VARS.md）
+- 既知の非関連課題（別タスク扱い）:
+  - hako_check/cli.hako の parse error（line表示の不整合）。FileBox配線とは無関係。HC012 JSON安定化の一環で対応予定。
+
+Next (handoff to Claude Code)
+- HC012 JSON 安定化（cli.hako）
+  - json‑lsp時は stdout を純JSON、ログは stderr の規約徹底（fmt判定ガードの再確認）
+  - parse error の発生箇所を修正（構文境界/コメント/Stage‑3トグル周り）
+  - `NYASH_JSON_ONLY=1 ./tools/hako_check.sh --format json-lsp tools/hako_check/tests/HC012_dead_static_box` が純JSONを返すこと
+- Analyzer run_tests 全緑の維持（--rules/--skip-rules で個別検証可能）
+8) FileBox provider 実装（リング0/1/選択ポリシー）と最小スモーク追加（core‑ro/auto/plugin-only）

 Next Steps (immediate)
-1) C: AST優先取り込みの最終化（text fallback を最小に）
+1) A（仕上げ）: HC012 line 精度（span_line）/ README 追随 / CLI I/F最終確認
-2) C: calls の arity 推定（実装済み）に基づく HC015 足場準備
+2) B（Parser強化）: tokenizer 文字列エスケープ/位置情報、parser_core 複数行・alias 抽出
-3) C: HC012 line 精度（span_line）適用（後回し可）
+3) C（可視化）: DOT 改善（box cluster / 孤立ノード）と quick スモーク追加
-4) `--format json-lsp` の代表テスト追加（OK/NG/edge）
 
 Context Compression Notes
 - A（診断I/F＋抑制）は実装済み。文字列診断→型付き変換あり。
 - B（AST: span_line/is_static=bool）は実装済み。methods.arity は既に出力。
 - C は ensure_array と calls arity 推定を反映。残は AST優先の徹底と HC012 line 精度。
+- HC021/HC031 は完了。PHI は AST パス限定で再発可能性があるため、当面 `--no-ast` 既定（`--force-ast` で明示オン）。
+- ルール検証は `--rules`/`--skip-rules` で二分探索可能。
 
 TODO (short-term, non-HC0)
 - AST-first intake: minimize text fallback; ensure analyzer never uses FileBox in tests.

+- Tests/CI/Analyzer run without plugins by default: `NYASH_DISABLE_PLUGINS=1` and `NYASH_JSON_ONLY=1`.
+- File I/O is avoided by passing source text via `--source-file <path> <text>`.
+- When plugins are needed (dev/prod), set `NYASH_FILEBOX_MODE=auto` and provide [libraries] in nyash.toml.
+
+Rules
+- Core implemented (green): HC011 Dead Methods, HC012 Dead Static Box, HC015 Arity Mismatch, HC016 Unused Alias, HC017 Non‑ASCII Quotes, HC018 Top‑level local, HC021 Analyzer IO Safety, HC022 Stage‑3 Gate, HC031 Brace Heuristics
+- Pending fixtures update: HC013 Duplicate Method, HC014 Missing Entrypoint
+
+CLI options
+- `--rules a,b,c` limit execution to selected rules.
+- `--skip-rules a,b` skip selected.
+- `--no-ast` (default) avoids AST parser; `--force-ast` enables AST path (use sparingly while PHI is under polish).
+
+Tips
+- JSON-only output: set `NYASH_JSON_ONLY=1` to avoid log noise in stdout; diagnostics go to stdout, logs to stderr.
+- For multiline `--source-file` payloads, CLI also provides HEX-escaped JSON in `NYASH_SCRIPT_ARGS_HEX_JSON` for robust transport; the VM prefers HEX→JSON→ARGV.
