+# Code Quality Dashboard Implementation Plan
+
+**Status:** Phase 1 Complete (Database Foundation)
+
+This document tracks the implementation of the Code Quality Dashboard for tracking architecture violations in the admin UI.
+
+---
+
+## Overview
+
+The Code Quality Dashboard provides a UI for viewing, managing, and tracking architecture violations detected by `scripts/validate_architecture.py`. This allows teams to:
+
+- View violations in a user-friendly interface
+- Track technical debt over time
+- Assign violations to developers
+- Prioritize fixes by severity
+- Monitor code quality improvements
+
+---
+
+## Implementation Phases
+
+### ✅ Phase 1: Database Foundation (COMPLETED)
+
+**Files Created:**
+- `app/models/architecture_scan.py` - Database models
+- `alembic/versions/7a7ce92593d5_*.py` - Migration
+
+**Database Schema:**
