NB-076 3b150b6c54 S14: 58-program benchmark suite — Lark grammar fixes + external COBOL validation 
Grammar fixes:
1. COPY regex: handle quoted names COPY "STD-REC.CPY"
2. Quoted name strip: remove quotes before file lookup
3. VALUE clause: support comma-separated 88-level values
4. PIC STRING: support decimal dot (ZZ9.99 -> PICTURE_STRING.99 + DOT)
5. LEVEL: use INT for level number (fixes 05/01/77 all levels)

Results on 58 telecom billing COBOL programs:
- Parse OK: 54/58 (93%)
- Parse fail: 4 (special chars: TAB, X'01', U'NNNN', &)
- Classification known issue: matching programs misclassified as
  '文件编成' because FILE-CONTROL keyword overrides matching signals
  (requires rule engine priority fix - separate issue)

NB-076 9cefbdf114 R16: 专家漏洞评审 — 发现并修复嵌套COPYBOOK解析bug 
评审方法：14项实机验证，非静态审查
  1. 非确定性输出检测 ✓ 5次运行值一致
  2. 边缘COBOL功能crash测试 (ALTER/ENTRY) ✓ 不崩溃
  3. 大规模程序性能 (500字段+250IF) ✓ 数秒完成
  4. 路径爆炸防护 (10IF in PERFORM UNTIL) ✓ 不爆炸
  5. 嵌套COPYBOOK解析 → 发现BUG并修复
  6. 嵌套IF深度  ✓
  7. 畸形JCL输入 (二进制/BOM/1000行延续) ✓ 不崩溃
  8. 注释中KEY字串误触发matching ✓ 不误报
  9. 变量名包含关键词子串FP ✓ WS-SORT-KEY不触发SORT
  10. 非COBOL输入 (中日文/HTML/二进制) ✓ 不误报
  11. OPEN I-O方向解析 ✓
  12. DataWriter JSON格式 ✓
  13. 跨运行隔离 ✓
  14. Config加载 ✓

修复: resolve_copybooks 增加递归参数+深度保护
  之前: COPY L1 -> L1.cpy含'COPY L2.'不被解析
  之后: 递归解析，上限10层防循环

NB-076 abb283669c R13: final sweep — EXEC stripping + INSPECT bugfix + more EQ assertions 
1. Lark: preprocess strips EXEC CICS/SQL...END-EXEC blocks
   -> CI01_CICS/DB01_SELECT_UPDATE now parse, 75/75 samples pass
2. propagate_assignments INSPECT TALLYING bugfix:
   was reading source from count_var (wrong field) instead of
   asgn['tgt']. Now CNT='005' instead of '003' for len(HELLO)=5.
3. 26 new EQ/falsifiable assertions added (propagate chains,
   orchestrator state, data_writer, report generator)
4. Hardened: ACCEPT DATE string len check, DataWriter JSON format

16 suites / 0 FAIL.

NB-076 4be2aae66d fix: 生产级 COBOL 程序解析 — COPY + OCCURS TO + FD 修复 
对抗性测试发现的生产程序解析缺陷和修复:

缺陷1: COPY 语句从未被预处理（18 个月 bug）
  - resolve_copybooks() 在 main() CLI 中调用但在 extract_structure() 路径中从未被调用
  - 修复: preprocess() 函数头部调用 resolve_copybooks()
  - 不可解析的 COPY 行被移除（避免 Lark 在 FD 块内遇到无法识别的指令）

缺陷2: Lark 语法的 fd 规则要求 data_item+ (至少一个记录)
  - 生产程序 FD 可以通过 COPY 引入记录定义
  - COPY 被移除后 FD 内无 data_item 导致 Lark 崩溃
  - 修复: fd 改为 data_item* (零或多个)

缺陷3: OCCURS 1 TO 100 TIMES（变量范围表）
  - 语法只支持 OCCURS INT TIMES，不支持 OCCURS 1 TO 100 TIMES
  - 修复: occurs_clause 增加 'TO' INT 可选部分

效果: 4 个生产程序中 2 个成功解析（CRDVAL, GENDATA）
  - 剩余 2 个（CRDCALC, CRDRPT）因固定格式续行限制未修复

全回归: 767 passed（0 new failures）

NB-076 dbee3b7251 fix: Lark grammar + parse_file_section SD/ASCENDING KEY support 
Bug fixes found through statement benchmark testing:
1. grammar.lark: Add ASCENDING/DESCENDING KEY IS + INDEXED BY to
   occurs_clause — fixes HINA024 (SEARCH ALL) parsing crash
2. grammar.lark: Add SD (Sort Description) entry type to file_section
   — fixes HINA034 (SORT), ST01, ST02 parsing crashes
3. read.py parse_file_section(): Handle SD blocks alongside FD blocks
   — enables SORT/MERGE file structure extraction

4 previously crashing files now parse successfully:
- HINA024.cbl (SEARCH ALL): paras=3, files=0
- HINA034.cbl (SORT): paras=1, files=3
- ST01_SORT.cbl: paras=2, files=3
- ST02_MERGE.cbl: paras=1, files=4

Regression: 749 passed (unchanged — classify_program internally caught
the crashes, so tests already 'passed'; real improvement is in data
quality: structure extraction now works for these programs)

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()
