Merge origin/cache

- Add thread safety: _anthropic_history_lock and _send_lock in ai_client to prevent concurrent corruption
  - Add _send_thread_lock in gui_2 for atomic check-and-start of send thread
  - Add atexit fallback in session_logger to flush log files on abnormal exit
  - Fix file descriptor leaks: use context managers for urlopen in mcp_client
  - Cap unbounded tool output growth at 500KB per send() call (both Gemini and Anthropic)
  - Harden path traversal: resolve(strict=True) with fallback in mcp_client allowlist checks
  - Add SLOP_CREDENTIALS env var override for credentials.toml with helpful error message
  - Fix Gemini token heuristic: use _CHARS_PER_TOKEN (3.5) instead of hardcoded // 4
  - Add keyboard shortcuts: Ctrl+Enter to send, Ctrl+L to clear message input
  - Add auto-save: flush project and config to disk every 60 seconds

+# Specification: GUIv2 Feature Parity
+
+## 1. Overview
+
+This track aims to bring `gui_2.py` (the `imgui-bundle` based UI) to feature parity with the existing `gui.py` (the `dearpygui` based UI). This involves porting several major systems and features to ensure `gui_2.py` can serve as a viable replacement and support the latest project capabilities like automated testing and advanced diagnostics.
+
+## 2. Functional Requirements
+
+### FR1: Port Core Architectural Systems
+- **FR1.1: Event-Driven Architecture:** `gui_2.py` MUST be refactored to use the `events.py` module for handling API lifecycle events, decoupling the UI from the AI client.
+- **FR1.2: MCP File Tools Integration:** `gui_2.py` MUST integrate and use `mcp_client.py` to provide the AI with native, sandboxed file system capabilities (read, list, search).
+
+### FR2: Port Major Features
+- **FR2.1: API Hooks System:** The full API hooks system, including `api_hooks.py` and `api_hook_client.py`, MUST be integrated into `gui_2.py`. This will enable external test automation and state inspection.
+- **FR2.2: Performance & Diagnostics:** The performance monitoring capabilities from `performance_monitor.py` MUST be integrated. A new "Diagnostics" panel, mirroring the one in `gui.py`, MUST be created to display real-time metrics (FPS, CPU, Frame Time, etc.).
+- **FR2.3: Prior Session Viewer:** The functionality to load and view previous session logs (`.log` files from the `/logs` directory) MUST be implemented, including the distinctive "tinted" UI theme when viewing a prior session.
+
+### FR3: UI/UX Alignment
+- **FR3.1: 'Hub' UI Layout:** The windowing layout of `gui_2.py` MUST be refactored to match the "Hub" paradigm of `gui.py`. This includes creating:
+    - `Context Hub`
+    - `AI Settings Hub`
+    - `Discussion Hub`
+    - `Operations Hub`
+- **FR3.2: Agent Capability Toggles:** The UI MUST include checkboxes or similar controls to allow the user to enable or disable the AI's agent-level tools (e.g., `run_powershell`, `read_file`).
+- **FR3.3: Full Theme Integration:** All new UI components, windows, and controls MUST correctly apply and respond to the application's theming system (`theme_2.py`).
+
+## 3. Non-Functional Requirements
+
+- **NFR1: Stability:** The application must remain stable and responsive during and after the feature porting.
+- **NFR2: Maintainability:** The new code should follow existing project conventions and be well-structured to ensure maintainability.
+
+## 4. Acceptance Criteria
+
+- **AC1:** `gui_2.py` successfully launches without errors.
+- **AC2:** The "Hub" layout is present and organizes the UI elements as specified.
+- **AC3:** The Diagnostics panel is present and displays updating performance metrics.
+- **AC4:** The API hooks server starts and is reachable when `gui_2.py` is run with the appropriate flag.
+- **AC5:** The AI can successfully use file system tools provided by `mcp_client.py`.
+- **AC6:** The "Prior Session Viewer" can successfully load and display a log file.
+- **AC7:** All new UI elements correctly reflect the selected theme.
+
+## 5. Out of Scope
+
+- Deprecating or removing `gui.py`. Both will coexist for now.
+- Any new features not already present in `gui.py`. This is strictly a porting and alignment task.

 3.  **Verify via ApiHookClient:** Use the `ApiHookClient` in `api_hook_client.py` to interact with the running application. It includes robust retry logic and health checks.
