feat: Phase 2 complete — 13 Phases of COBOL type classification and test benchmark

P0.6: gcov infrastructure
P1: extract_structure output expansion (11 new feature fields)
P2: Confusion group rule engine (8 pairs + contradiction + backtrack)
P3: 4-factor confidence calculation + quality gate update
P4: 33+2 COBOL program type test samples (22 files, 7 categories)
P5: parametrized/ test data generation engine
P6: japanese_data.py lookup tables
P7-10: Type-specific test suites (~159 parametrized tests)
P11: Full classification pipeline (classify_program) + orchestrator integration
P12: Documentation (module-interfaces, test-plan v3.0, coverage-matrix)

Architecture decisions:
- classification_pipeline/ merged to hina/pipeline/
- parametrized/ as independent module
- japanese_data.py as root-level file
- hina/__all__ only exports classify_program()

+# 贡献指南 — 模块化开发规则
+
+> 本文档定义多人协作开发本项目的规则。**所有开发者必须遵守。**
+
+---
+
+## 1. 模块分层
+
+```
+Layer 1: data/          ← 核心数据模型（所有人共享）
+Layer 2: cobol_testgen/ config/ jcl/parser/ quality/ report/ preprocessor/
+                        ← 业务引擎（每人负责 1-2 个）
+Layer 3: hina/ agents/ comparator/ runners/
+                        ← 高级引擎（每人负责 1 个）
+Layer 4: orchestrator/ web/ jcl/executor/
+                        ← 管道集成（H 负责）
+```
+
+**规则**: 下层不能依赖上层。Layer 2 不能 import Layer 3。
+
+---
+
+## 2. `__all__` 规则
+
+每个模块的 `__init__.py` 必须有 `__all__`。
+
+```
+在 `__init__.py` 中:
+  ✅ __all__ 里的 = 公开 API（其他人可依赖）
+  ❌ __all__ 外的 = 内部实现（随时可改）
+```
+
+**只有 `__all__` 中列出的函数/类是稳定接口**。修改 `__all__` 外的代码不需要通知其他人。修改 `__all__` 内的代码必须：
+1. 更新 `docs/module-interfaces.md`
+2. 在 PR 中标注 `[BREAKING]`
+3. 通知所有使用者
+
+---
+
+## 3. 导入规则
+
+### ✅ 正确做法: 只从模块顶层导入
+
+```python
+# ✅ Layer 2 → Layer 1
+from data import Field, FieldTree, VerificationRun
+
+# ✅ Layer 3 → Layer 1
+from data import TestCase, TestSuite
+
+# ✅ Layer 3 → Layer 2
+from cobol_testgen import extract_structure
+
+# ✅ Layer 4 → 各层
+from hina import gate_check, compute_confidence
+from comparator import compare_field
+from runners import CobolRunner
+```
+
+### ❌ 错误做法: 钻入模块内部
+
+```python
+# ❌ 不要直接从子模块导入 — 你的代码会依赖内部结构
+from cobol_testgen.coverage import check_coverage    # ❌
+from hina.gate import check                          # ❌
+from runners.cobol_runner import CobolRunner         # ❌
+from agents.agent1_parser import Agent1Parser        # ❌
+```
+
+**为什么**: 如果子模块重构（改名、拆分、合并），钻入内部的代码全部断裂。而模块顶层的 `__all__` 提供了稳定抽象层。
+
+---
+
+## 4. 数据模型契约
+
+### 4.1 所有模块共用 data/ 下的 3 组类
+
+| 类 | 用途 | 属于谁 |
+|:---|:-----|:-------|
+| `Field`, `FieldTree` | 字段树 | cobol_testgen → → comparator |
+| `TestCase`, `TestSuite`, `SparkConfig` | 测试数据 | cobol_testgen → → runners |
+| `FieldResult`, `VerificationRun` | 管道结果 | orchestrator → → comparator → → report |
+
+### 4.2 修改 data/ 的规则
+
+1. **必填字段** 直接添加到 dataclass（有默认值则向后兼容）
+2. **可选字段** 使用 `Optional` 或 `""` 默认
+3. **删除字段** 必须标注 `[BREAKING]`，检查所有使用处
+4. **修改字段含义** 必须更新 `data/__init__.py` 的文档注释
+
+**修改 data/ 必须通知所有开发者**（微信群 / PR 标注 `[DATA-CHANGE]`）。
+
+---
+
+## 5. 函数签名规则
+
+### 5.1 必须加类型注解
+
+```python
+# ✅ 正确
+def extract_structure(cobol_source: str, source_dir: str = None) -> dict:
+
+# ❌ 错误 — 调用者不知道参数类型
+def extract_structure(cobol_source, source_dir=None):
+```
+
+### 5.2 返回值必须符合 `data/` 模型
+
+- 函数返回多个值 → 包装成 dataclass
+- 函数返回可选 → `Optional[...]`
+- 函数返回集合 → `list[...]` 明确元素类型
+
+### 5.3 不要用 dict 当"隐式接口"
+
+```python
+# ❌ 返回无类型 dict — 调用者需要读实现才知道 key 名
+def run() -> dict:
+    return {"status": "ok", "matched": 5}
+
+# ✅ 返回类型化的对象
+def run() -> VerificationRun:
+    return vr
+```
+
+已有 `verificationRun` 这样的完整数据类，优先复用。
+
+---
+
+## 6. 测试规则
+
+### 6.1 测试文件位置
+
+```
+tests/
+├── cobol_testgen/    ← A 的测试
+├── hina/             ← D 的测试
+├── agents/           ← E 的测试
+├── config/           ← B 的测试
+├── comparator/       ← F 的测试
+├── runners/          ← G 的测试
+├── data/             ← 所有人的数据模型测试
+├── nonfunctional/    ← 性能/并发/安全
+└── test_*.py         ← 跨模块集成测试（H 负责）
+```
+
+### 6.2 测试用例命名
+
+```python
+def test_[模块]_[功能]():    # ✅ 推荐
+def test_extract_structure_simple_if():
+```
+
+### 6.3 测试覆盖要求
+
+- 新功能必须附带测试
+- 修复 bug 必须附带回归测试
+- 覆盖率目标: 核心管道 ≥ 85%，各模块 ≥ 70%
+
+---
+
+## 7. Config 修改规则
+
+`config/__init__.py` 的 `Config` 类是所有模块共享的配置。
+
+修改 Config 的规则:
+1. **加字段**: 添加到 dataclass（有默认值）
+2. **删字段**: 必须标注 `[BREAKING]`，检查所有使用者
+3. **改含义**: 更新 `docs/module-interfaces.md`
+
+Config 的字段格式示例:
+```python
+runner_mode: str = "native"
+# 取值: "native" | "spark"
+# 负责: G (runners 组)
+# 默认说明: 优先使用本地 Java 执行，无 Spark 依赖
+```
+
+**每个 Config 字段必须标注取值范围和负责组**。
+
+---
+
+## 8. 模块负责人一览
+
+| 模块 | 负责人 | __all__ 公开 API |
+|:-----|:------|:-----------------|
+| `cobol_testgen/` | A | extract_structure, generate_data, incremental_supplement, check_coverage |
+| `config/` | B | Config |
+| `preprocessor/` | B | CopybookPreprocessor |
+| `report/` | B | ReportGenerator |
+| `quality/` | C | L1OffsetValidator, L2RoundtripValidator |
+| `jcl/` | C | parse_jcl, JclExecutor, Job, JobStep, DDEntry, CondParam |
+| `hina/` | D | gate_check, compute_confidence, classify_with_llm, supplement, RetryHandler, collect_gcov |
+| `agents/` | E | LLMClient, Agent1Parser, Agent2Data, Agent3Diagnostic |
+| `comparator/` | F | align_records, compare_field, CobolBinaryReader, Normalizer, detect_rounding |
+| `runners/` | G | CobolRunner, NativeJavaRunner, SparkJavaRunner, DataWriter |
+| `storage/` | G | DiskCache, ReportStore, TestDataBundle |
+| `data/` | **所有人** | Field, FieldTree, TestCase, TestSuite, SparkConfig, FieldResult, VerificationRun |
+| `orchestrator/` | H | run_pipeline |
+| `web/` | H | FastAPI app, Worker |
+
+---
+
+## 9. 新增模块规则
+
+新增模块时的检查清单:
+
+- [ ] 创建目录 + `__init__.py`
+- [ ] `__init__.py` 包含 `__all__`
+- [ ] `docs/module-interfaces.md` 更新接口描述
+- [ ] 确认依赖方向正确（不反向依赖）
+- [ ] 写测试文件
+- [ ] 创建人加入模块负责人表
+

+## 八、多人协作分工方案
+
+| 开发者 | 模块 | 需知接口 | 独立程度 |
+|:-------|:-----|:---------|:---------|
+| **A** | `cobol_testgen/` (read/core/cond/design/coverage/output) | data/ 数据模型 | ✅ 完全独立 |
+| **B** | `config/` + `preprocessor/` + `report/` | data/diff_result.py | ✅ 完全独立 |
+| **C** | `quality/` + `jcl/parser/` | data/field_tree.py | ✅ 完全独立 |
+| **D** | `hina/` (pipeline/classifier/gate/agent/strategy/retry/gcov/rule_engine) + `coverage/` | data/diff_result.py | ✅ 完全独立 |
+| **E** | `agents/` (LLM/parser/data/diagnostic) | data/ 全部 3 个模型 | ✅ 完全独立 |
+| **F** | `comparator/` (align/compare/reader/normalize/round) | data/全部 | ✅ 完全独立 |
+| **G** | `runners/` (cobol/java/spark/datawriter) | data/test_case.py | ✅ 完全独立 |
+| **I** | `parametrized/` + `japanese_data.py` | 无 | ✅ 完全独立 |
+| **H** | `orchestrator.py` (集成)+ `web/` + `jcl/exec` | 所有模块 API | ⛓️ 需要所有人 |
+
+**各 Layer 3 模块只有 1 个统一约束**: 接收的输入必须是 data/ 中的数据类实例，返回的也必须是 data/ 中的数据类实例。只要遵守这个契约，模块开发者不需要知道其他模块的内部实现。
+
+---
+
+## 九、当前系统问题 & 改进项
+
+| 问题 | 影响 | 解决方案 |
+|:-----|:-----|:---------|
+| **`cobol_testgen/__init__.py` 混用公开和私有符号** (如 `_add_subscript`/`_init_child_names`) | 外部不清楚哪些是稳定接口 | 添加 `__all__` 明确定义公开 API |
+| **多数模块没有 `__all__`** | 无法区分公开/内部函数 | 每个模块根文件添加 `__all__` |
+| **orchestrator 直接 import 内部子模块** (如 `cobol_testgen.coverage.check_coverage`) | Layer 越界，管道依赖了引擎内部 | orchestrator 只应 import 各模块的顶层公开函数 |
+| **Config 字段没有验证/文档** | 修改 Config 可能破坏其他模块 | 添加字段校验 + 注释 |
+| **函数签名缺少类型注解** (部分历史代码) | 接口不明确 | 补全所有公开函数的类型注解 |
+| **没有模块版本号/变更记录** | 无法追踪接口变更 | 添加 `__version__` 到每个模块 |

+## 1. 设计总则
+
+### 1.1 新增 Phase 0.6: gcov 基础设施
+
+> 在 Phase 1 之前完成，为所有类型测试提供 gcov 能力。
+> 负责: F | 工作量: 3h
+
+为覆盖率测试体系提供可自动化运行的基础设施。Phase 7-10 中所有 gcov 测试的前置条件。
+
+| 步骤 | 内容 | 工作量 |
+|:-----|:-----|:------|
+| 1 | `cobc --coverage` 环境验证自动化 | 0.5h |
+| 2 | `collect_gcov()` 路径修复（含中文目录兼容）| 1h |
+| 3 | `Config` 追加 gcov_enabled / gcov_work_dir / gcov_threshold | 0.5h |
+| 4 | `test_gcov_basic.py` — gcov 全链路验证测试 | 1h |
+
+**验收**: cobc --coverage 编译 → 运行 → .gcda 生成 → collect_gcov() line_rate > 0
+
+```python
+# config/__init__.py — Config 新增字段
+gcov_enabled: bool = False
+gcov_work_dir: str = ".gcov_output"
+gcov_threshold: float = 0.5
+```
+
+### 1.3 分层原则
+
+```
+Layer 1: data/  — 所有模块共享的数据契约
+Layer 2: 核心引擎 — cobol_testgen/ config/ jcl/ quality/ report/ preprocessor/
+Layer 3: 业务引擎 — hina/ agents/ comparator/ runners/
+Layer 4: 管道集成 — orchestrator/ web/
+
+依赖方向: Layer 1 ← Layer 2 ← Layer 3 ← Layer 4
+禁止逆向依赖。
+```
+
+### 1.4 模块通信规则
+
+- 所有模块间通信通过 `data/` 层的数据类进行
+- 每个模块的公开 API 由 `__init__.py` 的 `__all__` 定义
+- 禁止钻入模块内部（如 `from cobol_testgen.coverage import ...`）
+- 详见 `CONTRIBUTING.md`
+
+### 1.5 最终模块布局（经架构审核确认）

+## 2. Phase 1: extract_structure 输出扩展
+
+### 2.1 目的
+
+当前 `extract_structure()` 输出的结构特征不足以判定 33+2 种程序类型。需要增加以下字段。
+
+### 2.2 新增输出字段
+
+在 `cobol_testgen/__init__.py` 的 `extract_structure()` 返回字典中追加：

+
+    # ── 变量命名模式检测 ──
+    "variable_patterns": {
+        "has_prev_key": True,                    # WS-PREV-* 模式变量

+
+### 2.3 实现位置
+
+| 新增特征 | 实现文件 | 实现方法 |
+|:---------|:---------|:---------|
+| SELECT 文件详情 | `read.py` 的 `parse_file_control()` 扩展 | 追加 organization 字段 |
+| DIVIDE/INSPECT/STRING | `core.py` `_BrParser` | 添加 IF 语句解析 |
+| PERFORM 模式分类 | `core.py` `_BrParser` | BrPerform 属性已存在 |
+| 主循环定位 | `core.py` 新函数 `locate_main_loop()` | 搜索含 READ 的 PERFORM 块 |
+| IF 类型统计 | `core.py` 新函数 `stat_if_types()` | 遍历 BrIf 的 condition |
+| 变量命名模式 | `core.py` 新函数 `detect_variable_patterns()` | 正则匹配字段名 |

+
+### 2.4 接口变更
+
+```python
+# cobol_testgen/__init__.py — __all__ 不变
+# extract_structure() 签名不变，返回字典追加新字段

+### 5.2 样本规范
+
+每个 COBOL 测试样本必须：
+
+1. **可编译** — 用 `cobc -x -std=ibm-strict` 编译通过
+2. **10-50 行** — 足够表达类型特征，不要过大
+3. **包含关键特征** — 每种类型独有的关键字和结构模式
+4. **有注释** — 开头的星号注释说明类型编号和名称
+5. **HEADER 注释**:
+
+```cobol
+      * ==== TYPE: MT01 マッチング(1:1) ====
+      * 特征: 2 输入文件 SELECT, IF KEY = 比较, 3路 IF, 无累加器
+      * BRANCHES: 4 (2 IFs), DECISIONS: 2
+      * SELECT COUNT: 2, OPEN COUNT: 2
+```
+
+### 5.3 实现顺序
+
+按依赖关系分 3 批创建：
+
+```
+第一批 (Phase 4a): 匹配系 10 种 + SORT/MERGE 2 种
+  依赖: 这 12 个样本是 Phase 7-8 测试的基础
+
+第二批 (Phase 4b): 分割系 3 种 + 校验 2 种 + 文件转换 3 种
+  依赖: 这 8 个样本是 Phase 7 测试的基础
+
+第三批 (Phase 4c): CICS 1 种 + DB 1 种
+  依赖: 需要模拟器环境，可先做代码样本，延迟测试
+```

+
+## 6. Phase 5: 参数化测试数据生成引擎
+
+### 6.1 独立模块 `parametrized/`（项目根目录）

+  parametrized/ → data/         (构造 Field/TestCase 对象)
+  cobol_testgen → parametrized  ❌ 禁止
+```
+
+**理由**：parametrized/ 的输入是数值参数（记录数、匹配率、不平衡比），不是 COBOL 源码。放在 cobol_testgen/ 下会使 COBOL 解析引擎依赖测试工具。独立模块保持分层干净。

+## 13. COBOL 覆盖率测试体系 — 与各 Phase 的集成
+
+> 覆盖率测试不是独立章节，而是贯穿多个 Phase 的基础设施。
+> 已在 Phase 1.1（Phase 0.6）中新增 gcov 基础设施。
+> 以下列出覆盖率的其他部分的分布位置：
+
+| 覆盖率内容 | 所在 Phase | 说明 |
+|:-----------|:----------|:------|
+| gcov 基础设施（环境验证 + collect_gcov 修复 + Config 字段 + 全链路测试）| **Phase 0.6** (1.1节) | F 负责，3h |
+| 质量门禁公式更新（quality_score_v2）+ 静态 vs 动态对比报告 | **Phase 3** (4.4节) | 新增 gcov 权重 40% |
+| 各类型 gcov 验证测试（约 15 个） | **Phase 7-10** | 每个类型群至少 1 条 gcov 测试 |
+| orchestrator gcov_enabled 集成 | **Phase 11** (9.5节) | 连接 Config → orchestrator → gate.py |
+
+### 13.1 覆盖率目标
+
+**模块覆盖率（pytest --cov）:**
+
+| 模块 | 目标 |
+|:-----|:----:|
+| cobol_testgen/* | ≥ 90% |
+| hina/* | ≥ 85% |
+| comparator/* | ≥ 85% |
+| runners/* | ≥ 70% |
+| orchestrator.py | ≥ 85% |
+
+**程序覆盖率（gcov 验证，各类型群最低 line_rate）:**
+
+| 类型群 | 门槛 | 理由 |
+|:-------|:----:|:------|
+| 条件分支(IF/EVALUATE) | ≥ 70% | 分支密集，应高覆盖 |
+| 匹配系 | ≥ 60% | 至少覆盖关键 IF 分支 |
+| SEARCH ALL | ≥ 60% | 命中/未命中均需覆盖 |
+| CALL | ≥ 60% | 主程序 + 子程序 |
+| SORT | ≥ 50% | 大量 I/O，代码行不多 |
+| 分割系 | ≥ 50% | 文件操作密集 |
+| 编辑输出 | ≥ 50% | WRITE 语句需要实际输出 |
+
+**静态 vs 动态差距**: 同类差距 ≤ 30%（超过说明静态分析不可靠）
+
+> 门槛说明：基于 HINA 现有 10 个程序的 gcov 预测数据。
+> 纯逻辑程序（IF/EVALUATE）可达 70%+，I/O 密集程序（SORT/分割）约 50%。
+> 上线后根据实测数据调整。

+
+1. **Lark 文法**: `SD` / `ASCENDING KEY` 未対応, HINA 2个测试跳过
+2. **Windows 编码**: `PYTHONIOENCODING=utf-8` 或 `python -X utf8` 必须, GBK 错误频繁
+3. **Docker 不可用**: 当前环境无 Docker Desktop, Spark runner 不可测试
+4. **外部依赖**: 実 COBOL 测试需要 WSL + GnuCOBOL + Java (GnuCOBOL 3.1.2.0, OpenJDK 17)
+5. **LLM API 成本**: Agent 测试依赖 LLM 调用, 缓存命中可降低成本
+6. **沙盒权限**: settings.json 需包含 `D:/cobol-java/**` 读写权限以便子 Agent 并行开发
