提升：37/37基准程序全量解析+O(N)路径枚举+运行时gcov验证

## 核心变更

### 1. 新PROCEDURE DIVISION解析器（procedure_parser.py）
- 行级状态机替换旧的BrParser regex解析器
- 覆盖：IF/ELSE/END-IF（嵌套）、EVALUATE/WHEN/ALSO、
  PERFORM UNTIL/VARYING、READ/AT END/NOT AT END、
  SORT/MERGE、GO TO DEPENDING ON
- 之前：3/37程序有分支检测  →  现在：37/37全部有分支
- 速度：~20ms/程序，纯规则引擎

### 2. 桥接层（pipeline_bridge.py）
- 新解析器为主，旧解析器3秒超时兜底
- 自动选取分支数更多的结果

### 3. 线性路径枚举（design_mcdc.py）
- 替换旧的Cartesian积路径枚举（O(2^N)）为每决策点独立枚举（O(N)）
- 28-sysin: 162分支仅163条路径（之前需截断到60DP）
- 消除了500路径硬上限和60DP截断

### 4. 条件解析修复（cond.py）
- NOT运算符规范化：X NOT = 5 → X <> 5
- 88-level反向：NOT WS-EOF-Y → parent <> value
- 裸字段引用：NOT WS-EOF → WS-EOF <> 'Y'
- 验证：1182个IF条件中0个NOT污染

### 5. 约束字段过滤（__init__.py）
- OF限定词剥离：STD-KEY OF MASTER-REC → STD-KEY
- 下标字段解析：WS-ITEM(SUB) → WS-ITEM
- 跳过不在fields_dict中的字段（group item/伪影）

### 6. 预处理器增强（read.py）
- VALUE ALL剥离（VALUE ALL '*' → VALUE '*'）
- &续行合并（COBOL多行字符串拼接）
- PIC小数点点→V转换（Z(9)9.99. → Z(9)9V99.）
- 缺少点号补全

### 7. Grammar修复（grammar.lark）
- OCCURS 1 TIME支持（原只认TIMES）
- USAGE IS COMP支持（可选IS）
- $符号在PICTURE_STRING中
- 无NAME条款支持（clause+）

### 8. Flatfile写入（flatfile.py）
- 多记录FD支持（选字段最多的记录）
- Path类型强制转换
- 回退零值记录

### 9. Bug修复
- trace_to_root空列表保护（core.py）

### 10. 测试套件（S16-S21）
- S16: 全量基准程序端到端
- S17: gcov运行时对比
- S18/S19: 桥接器验证
- S20: DISPLAY插桩运行时验证+gcov分支覆盖率
- S21: 条件解析修复验证
- 全部17/17回归测试通过

+> 日期: 2026-06-21 | 对象: D:\cobol-java\cobol-java-v3
+> 范围: COBOL 85/2002 语句类型全覆盖 × 解析/数据生成/分类 三维度
+
+---
+
+## 1. 总览
+
+### 1.1 目标
+
+建立 COBOL 语句级别的测试基准，验证平台对每种 COBOL 语句的：

+- **路径生成** — 是否能生成覆盖该语句所有分支的测试数据
+- **程序分类** — HINA pipeline 能否正确判定含该语句的程序类型
+- **覆盖率统计** — 静态分析能否正确统计该语句贡献的分支数
+
+### 1.2 范围

+
+现有 `test-data/cobol/` 下 33 个样本程序，按类别：
+
+| 类别 | 程序数 | 文件名 | 覆盖的语句 |
+|:-----|:------:|:-------|:-----------|

+### 2.4 解析器支持类型说明
+
+解析器对语句的支持分三种等级:
+
+| 等级 | 含义 | 语句 |
+|:-----|:------|:------|
+| ✅ **专用解析器** | core.py 中有 `_parse_*` 方法 | IF/EVALUATE/PERFORM/SEARCH/INITIALIZE/STRING/UNSTRING/CALL/ACCEPT/READ/WRITE/REWRITE/SET/INSPECT + 全部算术赋值(MOVE/COMPUTE/ADD/SUB/MULT/DIV) |
+| ⚠️ **Pass-through** | 解析器无专用方法，跳过但不中断流程 | CLOSE/DELETE/DISPLAY/START/CONTINUE |
+| ❌ **无处理** | 解析器无法识别，可能产生意外结果 | ALTER/USE/MERGE/SORT/RELEASE/RETURN/EXECUTE/GENERATE |
+
+> **注意:** MERGE 和 SORT 在分类器 (classifier.py) 中有关键词检测，但在解析器中是 pass-through。

+
+### 4.1 L0: 语句级单元测试 (cobol_testgen 解析层)
+
+每类语句的解析逻辑应有独立的 pytest 测试：
+
+```python
+# tests/parametrized/test_statements/
+#   test_arithmetic_statements.py
+#   test_move_statements.py
+#   test_file_statements.py
+#   test_control_statements.py
+#   test_search_statements.py
+#   test_sort_statements.py
+```
+
+每个测试模式（xUnit parametrized × 样本文件）：
+
+```python
+@pytest.mark.parametrize("cbl_file,expected", [
+    ("ST-ADD-TO.cbl", {"has_add": True, "branch_count": 2}),
+    ("ST-ADD-GIVING.cbl", {"has_add": True, "has_giving": True}),
+])
+def test_statement_parse(cbl_file, expected):
+    source = (FIXTURES_DIR / cbl_file).read_text("utf-8")
+    struct = extract_structure(source)
+    # assert 解析结果匹配 expected
+```

+
+## 7. 实施步骤
+
+### Phase A: P0 样本编写 (32 个 .cbl)
+
+```bash
+mkdir -p test-data/cobol/statement_arithmetic/
+mkdir -p test-data/cobol/statement_move/
+mkdir -p test-data/cobol/statement_file/
+mkdir -p test-data/cobol/statement_control/
+mkdir -p test-data/cobol/statement_inspect/
+```
+
+编写 32 个样本后运行验证脚本确保语法正确。
+
+### Phase B: L0 测试实现
+
+```bash
+mkdir -p tests/parametrized/test_statements/
+```
+
+8 个 parametrized 测试文件，覆盖 ~165 个测试点。
+
+### Phase C: L1 数据生成验证
+
+```bash
+# 验证所有 P0 样本
+python -c "
+from cobol_testgen import extract_structure, generate_data
+import glob
+for f in glob.glob('test-data/cobol/statement_*/*.cbl'):
+    src = open(f).read()
+    s = extract_structure(src)
+    d = generate_data(src)
+    print(f'{f}: branches={s[\"total_branches\"]}, records={len(d)}')
+"
+```
+
+### Phase D: L2 分类器验证
+
+```bash
+python -c "
+from hina.pipeline import classify_program
+import glob
+for f in glob.glob('test-data/cobol/statement_*/*.cbl'):
+    src = open(f).read()
+    r = classify_program(src)
+    print(f'{f}: {r[\"category\"]} conf={r[\"confidence\"]:.2f}')
+"
+```
+
+### Phase E-F: P1/P2
+
+按优先级逐步补充。
+
+---
+
+## 8. 已知限制
+
+1. **CICS/SQL 语句**: 使用 `*>` 注释模拟，不实际编译。L0 仅测试关键词解析
+2. **GO TO DEPENDING ON**: COBOL 85 标准，解析器支持但样本需跨段落跳转
+3. **ALTER**: 已废弃但大型机遗产代码仍存在。解析器需补充 ALTER 语句节点
+4. **DECLARATIVES**: 解析器 _BrParser 当前未处理 USE/DECLARATIVES 段
+5. **MOVE CORRESPONDING**: 解析器支持 MOVE 但不支持 CORR 子句扩展
+6. **MERGE OUTPUT PROCEDURE**: 解析器支持 MERGE 但不支持 PROCEDURE 扩展
+7. **Windows 编码**: 样本统一 UTF-8，使用 `python -X utf8` 运行
+
+---
+
+## 附录: 优先级依据
+
+| 优先级 | 判定标准 | 语句 |
+|:-------|:---------|:------|
+| **P0** | 平台现有解析器已支持 + 缺失独立样本 | ADD/SUBTRACT/MULTIPLY/COMPUTE/ACCEPT/INITIALIZE/SEARCH/READ/WRITE 等 |
+| **P1** | 解析器支持但语法变体多 + 迁移场景常见 | CICS/SQL/SEARCH VARYING/INSPECT advanced/SORT/MERGE/分类器关键字样本 |
+| **P2** | 遗产代码较少 + 解析器部分/不支持 | ALTER/CONTINUE/USE/DECLARATIVES/EXECUTE/交易控制(CANCEL/COMMIT/ROLLBACK) |

+
+## 9. Gap Analysis — 与完整 COBOL 85 标准的差异
+
+### 9.1 总览
+
+以下为计划与 COBOL 85 标准 + 主流程迁移场景的完整差异分析。
+
+| 维度 | 标准语句数 | 计划覆盖 | 不覆盖 | 覆盖率 |
+|:-----|:---------:|:--------:|:-----:|:-----:|
+| COBOL 85 过程语句 | ~42 | 40 | 2 (ENTER, GENERATE) | **95%** |
+| CICS 语句 (迁移相关) | ~10 | 7 | 3 | **70%** |
+| SQL 语句 (迁移相关) | ~10 | 7 | 3 | **70%** |
+| 分类器关键字样本 | ~11 | 7 | 4 | **64%** |
+
+### 9.2 计划内但解析器需补充的语句
+
+以下语句在计划中有样本，**但解析器 core.py 当前不支持**（pass-through 或缺失）：
+
+| 语句 | 当前状态 | 需补充 | 影响 |
+|:-----|:--------:|:-------|:------|
+| DELETE FILE | ⚠️ pass-through | `_parse_delete()` | 解析器无法追踪文件删除操作 |
+| START | ⚠️ pass-through | `_parse_start()` | 解析器无法追踪文件定位 |
+| ALTER | ⚠️ pass-through | `_parse_alter()` | 覆盖遗留代码中的 ALTER 语句 |
+| CONTINUE | ⚠️ pass-through | `_parse_continue()` | 低风险，CONTINUE 是空操作 |
+| USE/DECLARATIVES | ❌ 无处理 | `_parse_use()` | 声明段解析，是大型机常见模式 |
+| SORT | ⚠️ pass-through | `_parse_sort()` | 解析器无法追踪排序过程 |
+| MERGE | ⚠️ pass-through | `_parse_merge_inline()` | 解析器无法追踪合并过程 |
+| RELEASE / RETURN | ⚠️ pass-through | SORT/MERGE 子句 | 排序合并子语句 |
+| MOVE CORRESPONDING | ❌ 无处理 | CORR 支持 | 低优先级，可延后 |
+
+### 9.3 计划未覆盖的标准 COBOL 语句
+
+| 语句 | 标准 | 不覆盖原因 | 建议 |
+|:-----|:----:|:-----------|:-----|
+| CANCEL | COBOL 85 | 释放程序内存，迁移中罕见 | **建议补充 P2** |
+| COMMIT | COBOL 85 | 事务控制。大型机批处理程序常用 | **建议补充 P2** |
+| ROLLBACK | COBOL 85 | 事务回滚，常与 COMMIT 搭配 | **建议补充 P2** |
+| DISPLAY | COBOL 85 | 输出语句，不产生分支。解析器 classify_field_roles 已扫描读取追踪 | **建议补充 P2**（低优先级，仅需 L0 验证样本） |
+| ENTER | COBOL 85 | 语言切换（汇编等），迁移中极罕见 | 可忽略 P3 |
+| EXHIBIT | COBOL 85 | 命名 DISPLAY 变体，已过时 | 可忽略 P3 |
+| GENERATE | COBOL 85 | Report Writer 功能，迁移不涉及 | 可忽略 P3 |
+
+### 9.4 计划未覆盖的 CICS 语句
+
+| 语句 | 用法 | 建议 |
+|:-----|:-----|:------|
+| **EXEC CICS LINK** | 程序间调用（最常用的 CICS 通信之一） | **建议补充 P1** |
+| **EXEC CICS XCTL** | 程序间转移控制 | **建议补充 P1** |
+| **EXEC CICS RETURN** | 返回至 CICS 调用链上层 | **建议补充 P1** |
+| EXEC CICS ADDRESS | 获取/设置工作区地址 | 可忽略 P3 |
+| EXEC CICS HANDLE | 异常条件处理 | 可忽略 P3 |
+
+### 9.5 计划未覆盖的 SQL 语句
+
+| 语句 | 用法 | 建议 |
+|:-----|:-----|:------|
+| **EXEC SQL COMMIT** | 事务提交（嵌入式 SQL 基本语句） | **建议补充 P2** |
+| **EXEC SQL ROLLBACK** | 事务回滚 | **建议补充 P2** |
+| EXEC SQL CONNECT | 数据库连接 | P3 |
+| EXEC SQL PREPARE | 动态 SQL 预编译 | P3 |
+
+### 9.6 分类器关键字样本覆盖不足
+
+HINA classifier 的 L1_RULES 中有 4 个关键字**当前没有任何独立的 COBOL 样本验证**：
+
+| 分类器关键字 | 匹配规则 | 现有样本 | 建议 |
+|:-------------|:---------|:--------:|:-----|
+| **IS INITIAL** | `PROGRAM-ID. X IS INITIAL.` | ❌ 无 | **P1 — 新增 ST-CLS-INITIAL.cbl** |
+| **SYSIN** | `SYSIN` 关键字 | ❌ 无 | **P1 — 新增 ST-CLS-SYSIN.cbl** |
+| **ORGANIZATION IS** | `ORGANIZATION IS INDEXED/RELATIVE` | ❌ 无 | **P1 — 新增 ST-CLS-ORG.cbl** |
+| **ALTERNATE RECORD KEY** | `ALTERNATE RECORD KEY IS ...` | ❌ 无 | **P1 — 新增 ST-CLS-ALTKEY.cbl** |
+
+这些不会影响平台功能，但 **classifier 的测试套件缺少对这 4 个分类的确信度验证**。如果没有样本阻止回归，未来重构 keyword 匹配时可能无意中破坏这 4 个分类而测试不敏感。
+
+### 9.7 矩阵不准确性追踪
+
+| 行 | 原值 | 实际值 | 修正版本 |
+|:---|:-----|:-------|:---------|
+| DELETE (FILE) | ✅ 解析支持 | ⚠️ 穿通 | v1.0 已修正 |
+| START | ✅ 解析支持 | ⚠️ 穿通 | v1.0 已修正 |
+| CLOSE | ✅ 解析支持 | ⚠️ 穿通 | v1.0 已修正 |
+| SORT | ✅ 解析支持 | ⚠️ 穿通 (关键词检测) | v1.0 已修正 |
+| MERGE | ✅ 解析支持 | ⚠️ 穿通 (关键词检测) | v1.0 已修正 |
+| RELEASE/RETURN | ✅ 解析支持 | ⚠️ 穿通 (SORT 子句) | v1.0 已修正 |
+| ALTER | ✅ 解析支持 | ⚠️ 穿通 (无解析器) | v1.0 已修正 |
+| CONTINUE | ✅ 解析支持 | ⚠️ 穿通 | v1.0 已修正 |
+| PERFORM 系列 | 矩阵缺失 | ✅ 解析支持 | v1.0 已添加 |
+| OPEN (OUTPUT/I-O) | ✅ 解析支持 | ⚠️ 扫描 (open_pattern) | v1.0 已修正 |
+| MOVE CORRESPONDING | ⚠️ 部分 | ❌ 不支持 | v1.0 已修正 |
+| USE/DECLARATIVES | ⚠️ 部分 | ❌ 无处理 | v1.0 已修正 |
+| EXECUTE | ⚠️ 部分 | ⚠️ 穿通 | v1.0 已修正 |
+
+### 9.8 CICS/SQL 注释模拟限制
+
+当前 CICS/SQL 样本使用 `*>` 注释关键词模拟：
+```
+*> EXEC CICS LINK PROGRAM('PGM01')
+*>     COMMAREA(WS-COMMAREA)
+*> END-EXEC.
+```
+
+这意味着：
+- `extract_structure()` **无法**从注释中提取分支结构
+- 分类器 `classify_program()` 仍能检测关键词 → 正确分类
+- 注释模拟样本**不经过 GnuCOBOL 编译检验语法正确性**
+
+如果需要编译级验证，需要 WSL 中安装 IBM Enterprise COBOL 或 GnuCOBOL 的 CICS 支持库（不在当前范围）。
+
+### 9.9 建议的补充优先级
+
+基于差异分析，建议的补充顺序：
+
+| 批次 | 内容 | 语句数 | 理由 |
