+# Implementation Summary: Phase 1 - Core Infrastructure & Auth
+
+## Overview
+
+This document summarizes the complete implementation of Phase 1 for VelociCompanion, a multi-tenant threat hunting companion for Velociraptor. All acceptance criteria have been met.
+
+## What Was Built
+
+### 🎯 Complete Backend API (FastAPI)
+
+#### Core Infrastructure
+- ✅ FastAPI application with 22 routes
+- ✅ PostgreSQL database integration via SQLAlchemy
+- ✅ Alembic database migrations configured
+- ✅ Docker containerization with health checks
+- ✅ Environment-based configuration
+
+#### Authentication System
+- ✅ JWT token-based authentication using python-jose
+- ✅ Password hashing with bcrypt (passlib)
+- ✅ OAuth2 password flow for API compatibility
+- ✅ Token expiration and validation
+- ✅ Secure credential handling
+
+#### Database Models (5 tables)
+1. **tenants** - Multi-tenant organization data
+2. **users** - User accounts with roles
+3. **hosts** - Monitored systems
+4. **cases** - Threat hunting investigations
+5. **artifacts** - IOCs and evidence
+
+#### API Endpoints (22 routes)
+
+**Authentication (`/api/auth`)**
+- `POST /register` - Create new user account
+- `POST /login` - Authenticate and receive JWT
+- `GET /me` - Get current user profile
+- `PUT /me` - Update user profile
+
+**User Management (`/api/users`)** - Admin only
+- `GET /` - List users in tenant
+- `GET /{user_id}` - Get user details
+- `PUT /{user_id}` - Update user
+- `DELETE /{user_id}` - Deactivate user
+
+**Tenants (`/api/tenants`)**
+- `GET /` - List accessible tenants
+- `POST /` - Create tenant (admin)
