# Proprietary runtime boundaries

These directories document deployment boundaries. They do not vendor platform
SDKs or credentials.

- `portable36`: generated dependency-free consumer for hosted Python 3.6.
- `joinquant`: JoinQuant upload/runtime contract.
- `qmt_builtin`: QMT built-in strategy runtime.
- `colab`: notebook runtime and data-upload boundary.

Current executable compatibility files remain under `platforms/`, `dist/` and
`notebooks/` until their golden-vector migrations complete.
