mafw.devtools.pyversions

Python version management business logic for the MAFw development tools.

This package implements GitLab issue #247: it makes the [tool.mafw] section of pyproject.toml the single canonical source of truth for the project’s Python version policy and keeps every derived location in pyproject.toml (classifiers, Hatch matrices, Hatch environments and pre-push commands) synchronized with that source.

The package is deliberately layered so that the pure, side-effect-free core can be tested in isolation from the TOML document and the CLI:

• identifiers — version-identifier parsing;

• config — the PythonConfig model;

• manager — the VersionManager transforms;

• derivations — canonical → derived projections;

• sync — the tomlkit PyprojectSyncService.

The scope is repository configuration management only: nothing in this package installs interpreters, resolves or installs dependencies, runs tests, or edits the GitLab CI configuration.
