把 Test/ 纳入 https://git.gvsds.com/GVSDS/Viper_RegressionTesting 。 1) 新增 .gitignore —— 只保留测试源码，剔除全部构建产物： 目录 **/output*/（output / output_opt / output_orig / output_verify / output_dbg）、 **/temp*/（temp / temp_opt）、**/.tpv_build/ 二进制 *.exe *.obj *.o *.out *.a *.lib *.dll 中间物 *.ll *.vpi *.pyi *.deps.txt *.deps.json *.doc.json *_sha1_map.txt _pyi_cache_v1.pkl _pyi_cache_v1.sig.json _shared_sym.json _phase1_manifest.json 其它 build_all.txt（构建日志）、*.log、__pycache__/、*.bak、IDE 目录 保留 App/*.vp、project.json / project_opt.json / project.vpj、README.md、两个 .py 实测 `git add -A --dry-run`：196 个文件，无任何构建产物混入。 2) TestsOverview.md → README.md（作为仓库首页文档）。 3) SequentialRegressionTest.py：7 处 TestsOverview.md 引用同步改为 README.md （文档串、OVERVIEW 路径、read_test_order 文档与报错文案、argparse description、 启动横幅）；同时修正入口路径 PROJECTRANS —— 旧值 <root>/Projectrans.py 已不存在， 改为 <root>/TransPyC/Projectrans.py（与 regression_test.py:45-48 记录一致）， 否则本脚本会以 "can't open file" 全量失败。 regression_test.py 无需改动：它按目录扫描 project.json 找项目，不引用该文档。

# 复现：NoVTable 多继承下跨 Mixin self. 方法调用
|
||
#
|
||
# 缺陷：BaseB.caller 内 `self.helper()`（helper 定义在兄弟 Mixin BaseA，
|
||
# 经 Combined 多继承组合）被 mangle 成 `<sha1>.BaseB.helper`
|
||
# （用调用者自身/直接父类做前缀），而定义符号是 `<sha1>.BaseA.helper`
|
||
# → ld.lld undefined symbol（TPV 侧 StmtGenMixin.translate_stmt 调
|
||
# self.translate_return 同根因，符号成 StmtGenDeclMixin.translate_return）。
|
||
# 期望：按实际定义类（BaseA）做前缀，或按最终组合类（Combined）。
