Installs governance on each LlmAgent's native callbacks (before/after_model_callback -> BEFORE/AFTER_MODEL, before/after_tool_callback -> TOOL_CALL/AFTER_TOOL) in place, walking the sub_agents tree. Self-registers via the uipath.governance.adapters entry point; unit-tested and cloud-verified end to end (CodedAgent03). BEFORE/AFTER_AGENT remain owned by the uipath-runtime wrapper.

…, framework-only can_handle) Mirror radu's LangChain-adapter review across the Google ADK adapter: - __init__: drop the import-time registration side-effect; registration only via the uipath.governance.adapters entry point. - can_handle: claim only a real google.adk BaseAgent; remove the duck-typed (name + model-callback / sub_agents) fallback. - docstring: 'governance host' instead of uipath-runtime internals. - tests: can_handle uses a real LlmAgent; duck-typed look-alikes are now rejected.

Pull request overview
Adds a governance adapter for Google ADK so the governance host can attach deep hooks (BEFORE_MODEL / AFTER_MODEL / TOOL_CALL / AFTER_TOOL) to ADK LlmAgent callback slots via entry-point discovery (no import-time registration).
Changes:
- Introduces
GoogleADKAdapterandGovernanceCallbacksto install/remove governance callbacks across an ADK agent tree. - Adds adapter registration function exposed via the
uipath.governance.adaptersentry point. - Adds unit tests covering
can_handle, attach/detach behavior, payload extraction, and enforcement semantics.

- Text-cap comment: refer to the governance host, not the uipath-runtime wrapper constant. - Test docstring: note can_handle uses a real google.adk LlmAgent (isinstance detection); only payload shapes are faked. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Summary
Adds a Google ADK governance adapter to
uipath-google-adk. It lets UiPath governance evaluate what a Google ADK agent does at the model and tool level, and block disallowed actions, without the agent author writing governance code. This package contains only the ADK-specific bridge.What it does
Detects a
google.adk.agents.BaseAgent(can_handleclaims only realBaseAgentinstances). ADK agents are executed by aRunnerthat holds its own reference to the agent, so the adapter installs governance directly onto eachLlmAgent's native callback attributes (mutating them in place) and returns the original agent rather than a proxy.Maps each native callback to a governance check:
before_model_callbackBEFORE_MODELafter_model_callbackAFTER_MODELbefore_tool_callbackTOOL_CALLafter_tool_callbackAFTER_TOOLEnforces by letting a
GovernanceBlockException(raised on a DENY decision) propagate, stopping the model call or tool. Any other error inside a governance hook is logged and swallowed, so a governance failure cannot break an otherwise-healthy agent run.Discovered through the
uipath.governance.adaptersentry point, so no explicit import is needed to register it.What it does not do
BEFORE_AGENT/AFTER_AGENT); those are owned by the governance host.uipath-core.
