LangBot/plugins/misc/AutoTranslate/SHARED_RUNTIME.md

Shared runtime source candidate (SDK >=0.7.4)

This source declares sharedRuntime: shared-runtime-v1 and componentModel: stateless-v1. It is source-reviewed for the multi-tenant contract; it is not certified and makes no claim of live tenant acceptance.

• Configuration (target_language, model, min_text_length, enable_private) is read per event with plugin.get_config(). Nothing from tenant config is copied onto the plugin, the Translator component or module globals.
• initialize() only logs; a shared worker is never initialized with another installation's settings, and no SDK process-global settings are modified.

Per event

• Translator._handle_message resolves the enable/disable flags, minimum length, target language and model for the event it is handling. When no model is configured it falls back to the first model returned by plugin.get_llm_models() for that invocation.
• The translation call plugin.translate(...) uses invoke_llm under the task-local invocation, so the Host model authority comes from the active installation.
• The listener replies through the per-event EventContext and retains nothing between events.

Identity

No upstream/tenant identity is derived; the plugin keeps no per-user state and calls no identity-scoped Host API.

Tests

tests/test_shared_runtime.py drives one plugin/component object graph across two distinct InstallationBinding values with the real SDK bind_invocation(...) and InstallationBinding, and asserts (a) target language/model/private gating are resolved per event, and (b) the model fallback follows the invocation. The LLM call is simulated; no live network or vendor account is used.

Known limits

• The plugin ships no requirements.txt: the suite depends only on the SDK, the standard library and pytest.
• Translation quality and language detection depend entirely on the Host-provided model.
• No claim of certification; independent review and two-Workspace invocation acceptance are still required.
