This allows downstream consumers (like the Home Assistant integration) to write high-fidelity integration tests using the real client library classes instead of fragile top-level mocks. New modules: - channel.py: FakeChannel in-memory transport implementing Channel protocol - simulator.py: RoborockDeviceSimulator base class - v1_simulator.py: V1VacuumSimulator with stateful command handlers - cloud.py: FakeRoborockCloud with HTTP endpoint mocking Tests split by module: - test_channel.py: FakeChannel subscribe/publish/notify - test_cloud.py: Discovery, login errors, dynamic device addition - test_v1_simulator.py: Trait refresh/reset, state transitions, push updates * docs: add comment explaining dss field in v1_simulator * feat: expose in_cleaning, in_returning, charge_status, and dss on V1VacuumSimulator * feat: expose dock_type configuration in V1VacuumSimulator * feat: honor publish_side_effect in simulator and raise NotImplementedError in base _handle_publish * refactor: inherit FakeChannel from Channel Protocol * refactor: type simulator consumables state using Consumable dataclass * refactor: type simulator dnd, clean summary and record using real dataclasses * refactor: type simulator status, network info and init status using real dataclasses * refactor: expose raw status and app_init dataclasses on simulator for direct test manipulation * refactor: export and define all simulator state default constants at package level * refactor: update _handle_app_get_init_status to serialize self.app_init and dynamically resolve status_info fields from self.status * test: add E2E test case for multiple simulators with independent network info overrides * refactor: replace FakeUserState with library UserData dataclass on FakeRoborockCloud * refactor: decouple default product id from device duid and share DEFAULT_PRODUCT_ID constant * refactor: rename self.servers to self.simulated_devices and restore hardcoded qiCNieZa in mock_data * refactor: delete redundant properties from V1VacuumSimulator and update trigger_push_update ✖ subject may not be empty [subject-empty] ✖ type may not be empty [type-empty] ✖ found 2 problems, 0 warnings ⓘ Get help: https://github.com/conventional-changelog/commitlint/#what-is-commitlint
