Unified HM QC Platform

Version: 1.0.0 Status: ✅ Production Ready

A comprehensive quality control platform merging multiple QC tools into a single unified web application with intelligent AI-powered validation, sophisticated scoring, and consolidated reporting.

---

Overview

The Unified HM QC Platform integrates four distinct quality control tools into a single, cohesive web application:

1. HM QC - PDF/Image quality control with AI-powered validation
2. Video QC (BETA) - Video quality control with technical specification checks
3. Video Master Adot Detection (BETA) - Intelligent 4-tier video matching system
4. Reporting - Consolidated reports from Box.com and internal QC modules

Key Features

• 🎯 Unified Interface - Single platform with tabbed navigation
• 🔒 Secure Authentication - Azure AD with JWT validation
• 🤖 AI-Powered - GPT-4o and Claude integration for intelligent validation
• 📊 Advanced Scoring - 0-100 confidence scoring with detailed breakdowns
• 🎨 H&M Branding - Consistent black (#000000) and yellow (#FFDD00) theme
• 🔄 Real-time Progress - SSE and polling support for long-running operations
• 📦 Modular Architecture - Flask blueprints for clean separation of concerns

---

# 2. Create virtual environment
python3 -m venv venv
source venv/bin/activate

# 3. Install dependencies
pip install --upgrade pip
pip install -r requirements.txt

# 4. Create .env file (see Configuration section)
cp .env.example .env
# Edit .env with your credentials

# 5. Initialize database

• 0-100 scoring (Pass: 90+, Warning: 70-89, Fail: <70)
• Real-time progress tracking
• HTML report generation

Workflow:

1. Upload PDF/image → 2. Select profile → 3. Execute QC → 4. View results with score → 5. Download report

2. Video QC Module (BETA) 🔶

Status: Basic Structure

Video quality control with technical validation.
