Feature: Code Coverage Boost As a developer I want to ensure all code paths are tested So that I achieve 85% test coverage Scenario: Test convert_exit_code function When I test convert_exit_code with various inputs Then convert_exit_code should handle all types correctly Scenario: Test CLI app commands directly When I test the CLI app commands Then all CLI commands should work correctly Scenario: Test exception handling When I test exception handling in main Then exception handling should return correct codes Scenario: Show lightweight CLI help output When I trigger the basic CLI help output Then the basic help output should list common commands Scenario: Ensure CLI subcommands are registered lazily When I ensure CLI subcommands are registered lazily Then the registration flag should stay enabled Scenario: Shortcut tell forwards actor override When I invoke the tell shortcut with an actor override Then the tell shortcut should forward the actor override Scenario: Shortcut build forwards actor override When I invoke the build shortcut with an actor override Then the build shortcut should forward the actor override Scenario: Test Settings class initialization When I create a Settings instance Then it should have default values Scenario: Test Settings production check When I check if Settings is in production mode Then it should return the correct production status Scenario: Test Settings database URL When I get the database URL from Settings Then it should return the configured database URL Scenario: Test Settings provider check When I check if any provider is configured in Settings Then it should return the provider status Scenario: Test platform module When I import and use the platform module Then ensure_cli_importable should work
