NB-076 e5ab3baa46 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

NB-076 0e7472598d fix: 跨文件KEY约束 + PERFORM分支统计 + 平面文件写入
1. 跨文件KEY约束(修复)
   匹配型程的M-KEY与D-KEY值不同导致匹配0条。
   修复: generate_data后处理检测IF KEY比较,
   前半记录对齐KEY值(8条匹配),后半保待差异(9条不匹配).
   实际cobc运行验证: MATCHED=8, PASS.

2. extract_structure PERFORM分支统计(修复)
   _walk函数未添加BrPerform决策点, total_branches缺失.
   修复: 为PERFORM UNTIL/VARYING决策点添加2分支(Enter/Skip).
   之前total_branches=0,现在=2.

3. flatfile.py(新增)
   COBOL固定长平面文件写入器.
   - analyze_fd_layout(): 从COBOL源码自动解析文件布局
   - write_flat_file(): 生成为COBOL可直接读取的二进制格式

NB-076 0b0a013f51 fix: 3 critical parsing bugs found through statement benchmark testing
Bug 1: ELSE IF breaks IF false_seq parsing (core.py)
- _parse_if checked self.clean() == 'ELSE' which fails on 'ELSE IF ...'
- Fix: use startswith('ELSE'), reinsert IF portion for recursive parse
- Impact: ALL ELSE IF chains were silently dropped (huge branch loss)

Bug 2: READ skip loop greedily consumes subsequent statements (core.py)
- READ's AT END / NOT AT END skip loop used bare advance() with no
  statement boundary detection
- Fix: add _stmt_boundary regex that stops on IF/PERFORM/READ/etc.
- Impact: everything after first READ was consumed as 'AT END' lines

Bug 3: _walk() in extract_structure doesn't descend into BrPerform (__init__.py)
- Branch counting _walk() only handled BrIf/BrEval/BrSeq
- IF statements inside PERFORM bodies were never counted
- Fix: add BrPerform.body_seq and BrSearch descent

Combined impact: matching programs (MT01-33) now correctly report
their branches instead of 0. Full regression: 749 passed (unchanged).

hangshuo652 bc1d56d1a4 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()
