67 production .py modules that the running PINK service imports but which were never committed: prod/bingx/ (HTTP client, market/user streams, journal, config), prod/clean_arch/ adapters/persistence/runtime/dita/dita_v2 production modules and their co-located tests. Rule going forward: every module imported by launch_dolphin_pink.py / pink_direct.py must appear in git ls-files. Excludes _backup dirs, __pycache__, and non-code files.
