Create ARCHITECTURE_AUDIT.md

Add comprehensive architecture audit document

This document provides a complete audit of the StrategyStack application:
- Maps all 40+ implementation files and their status
- Identifies 10 implemented agent modules not exposed to UI
- Documents the fully-implemented DataEnrichmentManager
- Lists all missing UI components and features
- Specifies required configuration parameters
- Provides implementation roadmap for functional UI

Key Finding: Application has NO user-facing functionality despite extensive backend implementation. This audit is the basis for building the missing UI layer.

Per user instruction: "map it all out and then audit your plan and determine what config / param / and items missing are"

+# StrategyStack Architecture Audit
+
+## Executive Summary
+
+This document provides a comprehensive audit of the StrategyStack application architecture, identifying:
+- **Implemented Components**: Fully functional backend and API integrations
+- **Partial Components**: Authentication and infrastructure with gaps
+- **Missing Components**: User-facing UI and interactive functionality
+- **Configuration Gaps**: Required parameters and setup needed
+
+**Critical Finding**: Application has ZERO functional user interface. Backend logic exists but is not exposed to end users.
+
+---
+
+## System Architecture Overview
+
+### 1. Core Application Layer
+
+#### app.py (15.7 kB)
+**Status**: ✅ FUNCTIONAL (with infrastructure)
+- **What exists**:
+  - Gradio UI framework initialized
+  - OAuth authentication via Hugging Face
+  - Event handlers for refresh functionality
+  - Error handling infrastructure (recently added)
+  - Logging system configured
+  - Pre-commit hooks for code quality
+
+- **What's missing**:
+  - Input components (Textbox, File upload, etc.)
+  - Interactive buttons tied to backend functions
+  - Data display components (Tables, Charts, etc.)
+  - Real-time update mechanisms
+  - User interaction flows
+  - Function calls that actually execute backend modules
+
+**Code Example of What Exists**: Event handlers defined but not connected to UI:
+```python
+demo.load(refresh_demo_on_app_load)
+demo.select(on_sample_select)
+```
+
+**Code Example of What's Missing**: No actual data input or processing interface
+
