Harden reliability, security, and UX across core modules

- 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
Port missing features to gui_2 and optimize caching

+- **Key Areas:**
+    - **Caching Mechanisms:** Verify Gemini context caching and Anthropic prompt caching implementation.
+    - **Tool Calling:** Audit function declarations, parameter schemas, and result handling.
+    - **History & Tokens:** Review message history management, token estimation accuracy, and context window handling.
+
+## Functional Requirements
+1. **SDK Audit:** Compare existing code patterns against the latest official Python SDK documentation for Gemini and Anthropic.
+2. **Feature Validation:**
+    - Ensure `google-genai` usage follows the latest `Client` and `types` patterns.
+    - Ensure `anthropic` usage utilizes `cache_control` correctly for optimal performance.
+3. **Discrepancy Remediation:** Implement code changes to align the implementation with documented standards.
+4. **Validation:** Execute tests to ensure that API interactions remain functional and improved.
+
+## Acceptance Criteria
+- Full audit completed for all AI SDK interactions.
+- Identified discrepancies are documented and fixed.

+# 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.

+# GUI Layout Audit Report
+
+## Current Panel Distribution
+The GUI currently uses a multi-column layout with hardcoded initial positions:
+
+1. **Column 1 (Left):** Projects (Top), Files (Mid), Diagnostics (Bottom).
+2. **Column 2 (Center-Left):** Screenshots (Top), Theme (Mid), System Prompts (Bottom).
+3. **Column 3 (Center-Right):** Discussion History (Full Height).
+4. **Column 4 (Right):** Provider (Top), Message (Mid-Top), Response (Mid-Bottom), Tool Calls (Bottom).
+5. **Column 5 (Far-Right):** Comms History (Full Height).
+
+## Identified Issues
+
+### 1. Context Fragmentation
+- **Projects**, **Files**, and **Screenshots** are related to context gathering but are split across two different columns.
+- **Base Dir** inputs are repeated for Files and Screenshots, taking up redundant vertical space.
+
+### 2. Configuration Fragmentation
+- **Provider** settings (API keys, models, temperature) are on the far right.
+- **System Prompts** (Global and Project) are in the center-bottom.
+- These should be unified into a single "AI Configuration" or "Settings" hub.
+
+### 3. Workflow Disconnect (The "Chat Loop")
+- The user composes in **Message**, views in **Response**, and then manually adds to **Discussion History**.
+- These three panels are physically separated (Column 3 vs Column 4), causing unnecessary eye travel.
+
+### 4. Visibility of Operations
+- **Diagnostics** and **Comms History** are related to monitoring "under the hood" activity but are at opposite ends of the screen (Far Left vs Far Right).
+- **Tool Calls** and **Last Script Output** are the primary way to see AI actions, but Tool Calls is small and Script Output is a popup that can be missed.
+
+### 5. Tactical UI Density
+- Heavy use of `dpg.add_separator()` and standard `dpg.add_text()` labels leads to "airy" panels that don't match the "Arcade" aesthetic of dense, information-rich displays.
+- Lack of clear visual grouping for related fields.
+
+## Recommendations for Phase 2
+- **Unify Context:** Merge Projects, Files, and Screenshots into a tabbed "Context Manager" panel.
+- **Unify AI Config:** Merge Provider and System Prompts into an "AI Settings" panel.
+- **Streamline Chat:** Position Discussion History, Message, and Response in a logical vertical or horizontal flow.
+- **Operations Hub:** Group Diagnostics, Comms History, and Tool Calls.
+- **Arcade FX:** Implement better visual cues (blinking, color shifts) for state changes.

+# GUI Reorganization Proposal: The "Integrated Workspace"
+
+## Vision
+Transform the current scattered window layout into a cohesive, professional workspace that optimizes expert-level AI interaction. We will group functionality into four primary dockable "Hubs" while maintaining the flexibility of floating windows for secondary tasks.
+
+## 1. Context Hub (The "Input" Panel)
+**Goal:** Consolidate all files, projects, and assets.
+- **Components:**
+    - Tab 1: **Projects** (Project switching, global settings).
+    - Tab 2: **Files** (Base directory, path list, wildcard tools).
+    - Tab 3: **Screenshots** (Base directory, path list, preview).
+- **Benefits:** Reduces eye-scatter when gathering context; shared vertical space for lists.
+
+## 2. AI Settings Hub (The "Brain" Panel)
+**Goal:** Unified control over AI persona and parameters.
+- **Components:**
+    - Section (Collapsing): **Provider & Models** (Provider selection, model fetcher, telemetry).
+    - Section (Collapsing): **Tunings** (Temperature, Max Tokens, Truncation Limit).
+    - Section (Collapsing): **System Prompts** (Global and Project-specific overrides).
+- **Benefits:** All "static" AI configuration in one place, freeing up right-column space for the chat flow.
+
+## 3. Discussion Hub (The "Interface" Panel)
+**Goal:** A tight feedback loop for the core chat experience.
+- **Layout:**
+    - **Top:** Discussion History (Scrollable region).
+    - **Middle:** Message Composer (Input box + "Gen + Send" buttons).
+    - **Bottom:** AI Response (Read-only output with "-> History" action).
+- **Benefits:** Minimizes mouse travel between input, output, and history archival. Supports a natural top-to-bottom reading flow.
+
+## 4. Operations Hub (The "Diagnostics" Panel)
+**Goal:** High-density monitoring of background activity.
+- **Components:**
+    - Tab 1: **Comms History** (The low-level request/response log).
+    - Tab 2: **Tool Log** (Specific record of executed tools and scripts).
+    - Tab 3: **Diagnostics** (Performance telemetry, FPS/CPU plots).
+- **Benefits:** Keeps "noisy" technical data out of the primary workspace while making it easily accessible for troubleshooting.
+
+## Visual & Tactile Enhancements (Arcade FX)
+- **State-Based Blinking:** Unified blinking logic for when the AI is "Thinking" vs "Ready".
+- **Density:** Transition from simple separators to titled grouping boxes and compact tables for token usage.
+- **Color Coding:** Standardized color palette for different tool types (Files = Blue, Shell = Yellow, Web = Green).
+
+## Implementation Strategy
+1. **Docking Defaults:** Define a default docking layout in `gui.py` that arranges these four Hubs in a 4-quadrant or 2x2 grid.
+2. **Refactor:** Modify `gui.py` to wrap current window contents into these new Hub functions.
+3. **Persistence:** Ensure `dpg_layout.ini` continues to respect user overrides for this new structure.

+# Specification: GUI Layout Audit and UX Refinement
+
+## Overview
+This track focuses on a holistic review and reorganization of the Manual Slop GUI. The goal is to ensure that AI tunings, diagnostic features, context management, and discussion history are logically placed to support an expert-level "Multi-Viewport" workflow. We will strengthen the "Arcade Aesthetics" and "Tactile Density" values while ensuring the layout remains intuitive for power users.
+
+## Scope
+- **Review Areas:** AI Configuration, Diagnostics & Logs, Context Management, and Discussion History panels.
+- **Paradigm:** Multi-Viewport Focus (optimizing floatable/dockable windows).
+- **Aesthetics:** Enhancement of Arcade-style visual feedback and tactile UI density.
+
+## Functional Requirements
+1. **Layout Audit:** Analyze current widget placement against holistic use cases. Identify "weirdly placed" features that don't fit the expert-focus workflow.
+2. **Multi-Viewport Optimization:** Refine dockable panel behaviors to ensure flexible multi-monitor setups are seamless.
+3. **Visual Feedback Overhaul:** Implement or enhance blinking notifications and state-change animations (Arcade FX) for tool execution and AI status.
+4. **Information Density Enhancement:** Increase tactile feedback and data density in diagnostic and context panels.
+
+## Non-Functional Requirements
+- **Performance:** Ensure layout updates do not introduce lag or violate strict state management principles.
+- **Consistency:** Maintain "USA Graphics Company" tactile interaction values.
+
+## Acceptance Criteria
+- A comprehensive audit report/plan for adjustments is created.
+- GUI layout is reorganized based on the audit results.
+- Arcade FX and tactile density enhancements are implemented and verified.
+- The redesign is refined iteratively based on user feedback.
+
+## Out of Scope
+- Modifying underlying AI SDK integration logic.
+- Implementing new core MCP tools.
+- Backend project management logic.

+# Specification: GUI Performance Investigation and Fix
+
+## Overview
+This track focuses on identifying and resolving severe frametime performance issues in the Manual Slop GUI. Current observations indicate massive frametime bloat even on idle startup, with performance significantly regressing (target 60 FPS / <16.6ms) since commit `8aa70e287fbf93e669276f9757965d5a56e89b10`.
+
+## Functional Requirements
+- **Deep Profiling:**
+    - Use the high-resolution component timing (implemented in previous tracks) to pinpoint the exact main loop component causing bloat.
+    - Verify if the issue is in DPG rendering, theme binding, telemetry gathering, or thread synchronization.
+- **Regression Analysis:**
+    - Examine changes since commit `8aa70e287fbf93e669276f9757965d5a56e89b10` to identify potentially expensive operations introduced to the main loop.
+- **Optimization:**
+    - Refactor or throttle any identified bottlenecks.
+    - Ensure that UI initialization or data aggregation does not block the main thread unnecessarily.
+
+## Non-Functional Requirements
+- **Target Performance:** Consistent 60 FPS (<16.6ms per frame) during idle operation.
+- **Stability:** Zero frames exceeding 33ms (spike threshold) during normal idle use.
+
+## Acceptance Criteria
+- [ ] Manual Slop GUI launches and maintains a stable <16.6ms frametime on idle.
+- [ ] Performance Diagnostics panel confirms the absence of >16.6ms spikes on idle.
+- [ ] The root cause of the regression is identified and verified through empirical testing.

+# 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.

+# Specification: UI Performance Metrics and AI Diagnostics
+
+## Overview
+This track aims to resolve subpar UI performance (currently perceived below 60 FPS) by implementing a robust performance monitoring system. This system will collect high-resolution telemetry (Frame Time, Input Lag, Thread Usage) and expose it to both the user (via a Diagnostics Panel) and the AI (via API hooks). This ensures that performance degradation is caught early during development and testing.
+
+## Functional Requirements
+- **Metric Collection Engine:**
+    - Track **Frame Time** (ms) for every frame rendered by Dear PyGui.
+    - Measure **Input Lag** (estimated delay between input events and UI state updates).
+    - Monitor **CPU/Thread Usage**, specifically identifying blocks in the main UI thread.
+- **Diagnostics Panel:**
+    - A new dedicated panel in the GUI to display real-time performance graphs and stats.
+    - Historical trend visualization for frame times to identify spikes.
+- **AI API Hooks:**
+    - **Polling Tool:** A tool (e.g., `get_ui_performance`) that allows the AI to request a snapshot of current telemetry.
+    - **Event-Driven Alerts:** A mechanism to notify the AI (or append to history) when performance metrics cross a "degradation" threshold (e.g., frame time > 33ms).
+- **Performance Optimization:**
+    - Identify the "heavy" process currently running in the main UI thread loop.
+    - Refactor identified bottlenecks to utilize background workers or optimized logic.
+
+## Non-Functional Requirements
+- **Low Overhead:** The monitoring system itself must not significantly impact UI performance (target <1% CPU overhead).
+- **Accuracy:** Frame timings must be accurate to sub-millisecond resolution.
+
+## Acceptance Criteria
+- [ ] UI consistently maintains "Smooth Frame Timing" (minimized spikes) under normal load.
+- [ ] Main thread load is reduced, evidenced by metrics showing less than 50% busy time during idle/light use.
+- [ ] AI can successfully retrieve performance data using the `get_ui_performance` tool.
+- [ ] AI is alerted when a simulated performance drop occurs.
+- [ ] The Diagnostics Panel displays live, accurate data.
+
+## Out of Scope
+- GPU-specific profiling (e.g., VRAM usage, shader timings).
+- Remote telemetry/analytics (data stays local).

+# Specification: Human-Like UX Interaction Test
+
+## Overview
+This track implements a robust, "human-like" interaction test suite for Manual Slop. The suite will simulate a real user's workflow—from project creation to complex AI discussions and history management—using the application's API hooks. It aims to verify the "Integrated Workspace" functionality, tool execution, and history persistence without requiring manual human input, while remaining slow enough for visual audit.
+
+## Scope
+- **Standalone Interactive Test**: A Python script (`live_walkthrough.py`) that drives the GUI through a full session, ending with an optional manual sign-off.
+- **Automated Regression Test**: A pytest integration (`tests/test_live_workflow.py`) that executes the same logic in a headless or automated fashion for CI.
+- **Target Model**: Google Gemini Flash 2.5.
+
+## Functional Requirements
+1. **User Simulation**:
+    - **Dynamic Messaging**: The test agent will generate responses based on the AI's output to simulate a multi-turn conversation.
+    - **Tactile Delays**: Short, random delays (minimum 0.5s) between actions to simulate reading and "typing" time.
+    - **Visual Feedback**: Automatic scrolling of the discussion history and comms logs to keep the "live" action in view.
+2. **Workflow Scenarios**:
+    - **Project Scaffolding**: Create a new project and initialize a tiny console-based Python program.
+    - **Discussion Loop**: Engage in a ~5-turn conversation with the AI to refine the code.
+    - **Context Management**: Verify that tool calls (filesystem, shell) are reflected correctly in the Comms and Tool Log tabs.
+    - **History Depth**: Verify truncation limits and switching between named discussions.
+3. **Session Management**:
+    - **Tab Interaction**: Programmatically switch between "Comms Log" and "Tool Log" tabs during operations.
+    - **Historical Audit**: Use the "Load Session Log" feature to load a prior log file and verify "Tinted Mode" visibility.
+
+## Non-Functional Requirements
+- **Efficiency**: Minimize token usage by using Gemini Flash and keeping the "User" prompts concise.
+- **Observability**: The standalone test must be clearly visible to a human observer, with state changes occurring at a "human-readable" pace.
+
+## Acceptance Criteria
+- `live_walkthrough.py` successfully completes a 5-turn discussion and signs off.
+- `tests/test_live_workflow.py` passes in CI environment.
+- Prior session logs are loaded and visualized without crashing.
+- Thinking and Live indicators trigger correctly during simulated API calls.
+
+## Out of Scope
+- Support for Anthropic API in this specific test track.
+- Stress testing high-concurrency tool calls.

 10.  **Announce Completion:** Inform the user that the phase is complete and the checkpoint has been created, with the detailed verification report attached as a git note.

+### Verification via API Hooks
+
+For features involving the GUI or complex internal state, unit tests are often insufficient. You MUST use the application's built-in API hooks for empirical verification:
+
+1.  **Launch the App with Hooks:** Run the application in a separate shell with the `--enable-test-hooks` flag:
+    ```powershell
+    uv run python gui.py --enable-test-hooks
+    ```
+    This starts the hook server on port `8999`.
+
+2.  **Use the pytest `live_gui` Fixture:** For automated tests, use the session-scoped `live_gui` fixture defined in `tests/conftest.py`. This fixture handles the lifecycle (startup/shutdown) of the application with hooks enabled.
+    ```python
+    def test_my_feature(live_gui):
+        # The GUI is now running on port 8999
+        ...
+    ```
+
+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.
+
+4.  **Verify via REST Commands:** Use PowerShell or `curl` to send commands to the application and verify the response. For example, to check health:
+    ```powershell
+    Invoke-RestMethod -Uri "http://127.0.0.1:8999/status" -Method Get
+    ```
