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 Co-Authored-By: Claude <noreply@anthropic.com>

2. Compile with --coverage + generate test data

3. Run the program

4. Run gcov -b → get per-line hit counts

5. Verify: every IF/ELSE/AT_END line identified by our parser is actually hit at runtime

6. If gcov shows 0 hits on a line we claim to cover, we have a bug.
