+# Implementation Plan: GUI 2.0 Feature Parity and Migration
+
+This plan follows the project's standard task workflow to ensure full feature parity and a stable transition to the ImGui-based `gui_2.py`.
+
+## Phase 1: Research and Gap Analysis
+Identify and document the exact differences between `gui.py` and `gui_2.py`.
+
+- [ ] Task: Audit `gui.py` and `gui_2.py` side-by-side to document specific visual and functional gaps.
+- [ ] Task: Map existing `EventEmitter` and `ApiHookClient` integrations in `gui.py` to `gui_2.py`.
+- [ ] Task: Write failing tests in `tests/test_gui2_parity.py` that identify missing UI components or broken hooks in `gui_2.py`.
+- [ ] Task: Verify failing parity tests.
+- [ ] Task: Conductor - User Manual Verification 'Phase 1: Research and Gap Analysis' (Protocol in workflow.md)
+
+## Phase 2: Visual and Functional Parity Implementation
+Address all identified gaps and ensure functional equivalence.
+
+- [ ] Task: Implement missing panels and UX nuances (text sizing, font rendering) in `gui_2.py`.
+- [ ] Task: Complete integration of all `EventEmitter` hooks in `gui_2.py` to match `gui.py`.
+- [ ] Task: Verify functional parity by running `tests/test_gui2_events.py` and `tests/test_gui2_layout.py`.
+- [ ] Task: Address any identified regressions or missing interactive elements.
+- [ ] Task: Conductor - User Manual Verification 'Phase 2: Visual and Functional Parity Implementation' (Protocol in workflow.md)
+
+## Phase 3: Performance Optimization and Final Validation
+Ensure `gui_2.py` meets performance requirements and passes all quality gates.
+
+- [ ] Task: Conduct performance benchmarking (FPS, CPU, Frame Time) for both `gui.py` and `gui_2.py`.
+- [ ] Task: Optimize rendering and docking logic in `gui_2.py` if performance targets are not met.
+- [ ] Task: Verify performance parity using `tests/test_gui2_performance.py`.
+- [ ] Task: Run full suite of automated GUI tests with `live_gui` fixture on `gui_2.py`.
+- [ ] Task: Conductor - User Manual Verification 'Phase 3: Performance Optimization and Final Validation' (Protocol in workflow.md)
+
+## Phase 4: Deprecation and Cleanup
+Finalize the migration and decommission the original `gui.py`.
+
+- [ ] Task: Rename `gui.py` to `gui_legacy.py`.
+- [ ] Task: Update project entry point or documentation to point to `gui_2.py` as the primary interface.
+- [ ] Task: Final project-wide link validation and documentation update.
+- [ ] Task: Conductor - User Manual Verification 'Phase 4: Deprecation and Cleanup' (Protocol in workflow.md)
