+# Implementation Plan: GUI Performance Fix
+
+## Phase 1: Instrumented Profiling and Regression Analysis
+- [ ] Task: Baseline Profiling Run
+    - [ ] Sub-task: Launch app with `--enable-test-hooks` and capture `get_ui_performance` snapshot on idle startup.
+    - [ ] Sub-task: Identify which component (Dialogs, History, GUI_Tasks, Blinking, Comms, Telemetry) exceeds 1ms.
+- [ ] Task: Regression Analysis (Commit `8aa70e2` to HEAD)
+    - [ ] Sub-task: Review `git diff` for `gui.py` and `ai_client.py` across the suspected range.
+    - [ ] Sub-task: Identify any code added to the `while dpg.is_dearpygui_running()` loop that lacks throttling.
+- [ ] Task: Conductor - User Manual Verification 'Phase 1: Instrumented Profiling and Regression Analysis' (Protocol in workflow.md)
+
+## Phase 2: Bottleneck Remediation
+- [ ] Task: Implement Performance Fixes
+    - [ ] Sub-task: Write Tests (Performance regression test - verify no new heavy loops introduced)
+    - [ ] Sub-task: Implement Feature (Refactor/Throttle identified bottlenecks)
+- [ ] Task: Verify Idle FPS Stability
+    - [ ] Sub-task: Write Tests (Verify frametimes are < 16.6ms via API hooks)
+    - [ ] Sub-task: Implement Feature (Final tuning of update frequencies)
+- [ ] Task: Conductor - User Manual Verification 'Phase 2: Bottleneck Remediation' (Protocol in workflow.md)
+
+## Phase 3: Final Validation
+- [ ] Task: Stress Test Verification
+    - [ ] Sub-task: Write Tests (Simulate high volume of comms entries and verify FPS remains stable)
+    - [ ] Sub-task: Implement Feature (Ensure optimizations scale with history size)
+- [ ] Task: Conductor - User Manual Verification 'Phase 3: Final Validation' (Protocol in workflow.md)
