API stability

Public namespace

New integrations should import from qf_solver:

from qf_solver import check_mesh, load_model, save_result, solve_model

The standard flow is load_model -> check_mesh -> solve_model -> save_result. The package version is available without importing implementation modules:

from qf_solver import __version__
print(__version__)

The solveur namespace remains a compatibility facade for existing 0.2.x applications. The recommended CLI is qf-solver; legacy entry points remain available for compatibility but should not be used in new integrations.

Compatibility boundary

JSON v1 inputs remain supported where the documented schema permits them. CLI commands and stable exit codes are part of the public interface. Interface stability does not qualify every element, analysis or material combination; the active capability matrix defines those boundaries.
