## role
Provides the core database model layer with a centralized public API, defining SQLAlchemy base classes and reusable mixins for consistent schema patterns across the API application.
## files
- __init__.py | Re-exports model classes from submodules to provide a centralized public API for the src.models package | dep: src.models.base, src.models.config.config_profile, src.models.project.git_repository, src.models.project.project, src.models.project.workspace, src.models.system.health_check, src.models.system.instance_event, src.models.system.notification, src.models.system.terminal_session, src.models.tool.tool_definition_manifest, src.models.tool.tool_instance, src.models.tool.tool_type, src.models.user.ssh_key, src.models.user.user, src.models.user.user_config
- base.py | Defines SQLAlchemy base model and reusable mixins for UUID primary keys and automatic timestamp tracking in database models. | exp: class:Base, class:UUIDPrimaryKeyMixin, class:TimestampMixin | dep: uuid, datetime, sqlalchemy, sqlalchemy.orm
## arch
Uses the declarative base pattern with mixin composition for cross-cutting concerns (UUIDs, timestamps), and a facade/aggregate module pattern via __init__.py re-exports to simplify imports for consumers.
