- Require Python 3.15 in project metadata, runtime pin, and Docker stages. - Use lazy imports for database backends and type-only dependencies. - Defer benchmark dependencies until their code paths are used. - Rely on deferred annotations and use Path.info for file discovery. - Accept BattlesnakeArena alongside BattlesnakeEngine on game endpoints. - Advance quart_common for Python 3.15 and multi-agent validation. - Add pytest development dependencies and refresh the uv lockfile. - Test lazy backend loading, import order, and fresh file discovery. - Document the runtime requirements and locked uv workflow. BREAKING CHANGE: Python 3.15 or newer is required; earlier runtimes cannot parse the lazy import syntax.
