Python Compatibility

Entroping Core supports Python 3.12 or 3.13 for the current alpha line. CI proves Python 3.12 and 3.13 with the security regression suite, and the optional-extras smoke lane proves the LiteLLM, mitmproxy, and Textual adapter boundaries on both versions.

Python 3.12 remains the syntax and mypy floor. Ruff targets py312, mypy runs with python_version = "3.12", and application code must stay compatible with the lowest supported runtime.

Entroping is not claimed for Python 3.14 until a compatibility issue adds CI evidence and updates pyproject.toml, this document, and release docs.

Package metadata intentionally uses:

requires-python = ">=3.12,<3.14"

That cap is a release-truth boundary, not a prediction that Python 3.14 will be incompatible. Remove or move the cap only after tests and optional dependency smokes pass under the new runtime.
