+# Specification: Event-Driven API Metrics Updates
+
+## Overview
+Refactor the API metrics update mechanism to be event-driven. Currently, the UI likely polls or recalculates metrics on every frame. This track will implement a signal/event system where `ai_client.py` broadcasts updates only when significant API activities (requests, responses, tool calls, or stream chunks) occur.
+
+## Functional Requirements
+- **Event System:** Implement a robust event/signal mechanism (e.g., using a queue or a simple observer pattern) to communicate API lifecycle events.
+- **Client Instrumentation:** Update `ai_client.py` to emit events at key points:
+    - **Request Start:** When a call is sent to the provider.
+    - **Response Received:** When a full or final response is received.
+    - **Tool Execution:** When a tool call is processed or a result is returned.
+    - **Stream Update:** When a chunk of a streaming response is processed.
+- **UI Listener:** Update the GUI components (in `gui.py` or associated panels) to subscribe to these events and update metrics displays only when notified.
+- **Decoupling:** Remove any metrics calculation or display logic that is triggered by the UI's main graphical update loop (per-frame).
+
+## Non-Functional Requirements
+- **Efficiency:** Significant reduction in UI main thread CPU usage related to metrics.
+- **Integrity:** Maintain 100% accuracy of token counts and usage data.
+- **Responsiveness:** Metrics should update immediately following the corresponding API event.
+
+## Acceptance Criteria
+- [ ] UI metrics for token usage, costs, and session state do NOT recalculate on every frame (can be verified by adding logging to the recalculation logic).
+- [ ] Metrics update precisely when API calls are made or responses are received.
+- [ ] Automated tests confirm that events are emitted correctly by the `ai_client`.
+- [ ] The application remains stable and metrics accuracy is verified against the existing polling implementation.
+
+## Out of Scope
+- Adding new metrics or visual components.
+- Refactoring the core AI logic beyond the event/metrics hook.

+- [x] Task: Refactor GUI performance tests (`tests/test_gui_performance_requirements.py`, `tests/test_gui_stress_performance.py`) to verify real metrics (FPS, memory) via hooks.
+- [x] Task: Audit and update all remaining tests in `tests/` to ensure they either use the live server or are explicitly marked as pure unit tests.

+# Specification: Live GUI Testing Infrastructure
+
+## Overview
+Update the testing suite to ensure all tests (especially GUI-related and integration tests) communicate with a live running instance of `gui.py` started with the `--enable-test-hooks` argument. This ensures that tests can verify the actual application state and metrics via the built-in API hooks.
+
+## Functional Requirements
+- **Server-Based Testing:** All tests must be updated to interact with the application through its REST API hooks rather than mocking internal components where live verification is possible.
+- **Automated GUI Management:** Implement a robust mechanism (preferably a pytest fixture) to start `gui.py --enable-test-hooks` before test execution and ensure it is cleanly terminated after tests complete.
+- **Hook Client Integration:** Ensure `api_hook_client.py` is the primary interface for tests to communicate with the running GUI.
+- **Documentation Alignment:** Update `conductor/workflow.md` to reflect the requirement for live testing and API hook verification.
+
+## Non-Functional Requirements
+- **Reliability:** The process of starting and stopping the GUI must be stable and not leave orphaned processes.
+- **Speed:** The setup/teardown of the live GUI should be optimized to minimize test suite overhead.
+- **Observability:** Tests should log communication with the API hooks for easier debugging.
+
+## Acceptance Criteria
+- [ ] All tests in the `tests/` directory pass when executed against a live `gui.py` instance.
+- [ ] New track creation (e.g., via `/conductor:newTrack`) generates plans that include specific API hook verification tasks.
+- [ ] `conductor/workflow.md` accurately describes the live testing protocol.
+- [ ] Real-time UI metrics (FPS, CPU, etc.) are successfully retrieved and verified in at least one performance test.
+
+## Out of Scope
+- Rewriting the entire GUI framework.
+- Implementing new API hooks not required for existing test verification.
