Enterprise Legal Vault: AI Classification & Multi-Jurisdictional Security

🎯 Description
This enterprise-grade legal document management system provides end-to-end automation for securing, classifying, and managing the lifecycle of sensitive documents. It is designed to handle high-stakes data across multiple jurisdictions (GDPR, CCPA, HIPAA) with AI-powered intelligence.

✨ What This Workflow Does
Intelligent Intake & Deduplication - Monitors Google Drive, Email, and Webhooks. It uses SHA-256 fingerprinting to ensure every document is unique and to prevent redundant processing.
AI-Powered Analysis Engine - Utilizes OpenAI/Claude to classify documents (NDA, MSA, Employment Agreements), detect jurisdiction, and assign a composite Risk Score (1-100).
Dynamic Security Enforcement - Translates business rules from Airtable into technical enforcement using the HTML to PDF (Lock) node:
Ultra-High Risk (90+): AES-256 encryption with disabled Print, Copy, and Modify permissions.
High Risk (50-89): AES-128 encryption with dynamic recipient-specific watermarking.
Public Filings: Timestamped watermarking with no encryption.
Lifecycle & Retention Automation - Automatically calculates retention expiry dates based on legal requirements. It sets Google Calendar renewal reminders at 90, 60, and 30-day intervals.
Intelligent Distribution Matrix -
Verified: Attached to HubSpot Deals and synced to Dropbox client folders.
Review: Flagged items are sent to a manual review queue with a Slack preview.
Failed: Isolated in a Quarantine folder with incident logging in Airtable.

💡 Key Features
Jurisdictional Logic:** Automatically adapts security and retention rules based on regional laws fetched from Airtable.
Forensic Watermarking:** Embeds tracking data (User ID, Timestamp) to deter and identify data leaks.
Fail-Safe Quarantine:** Prevents unverified or risky documents from ever entering the primary company storage.

📦 Requirements
HTML to PDF Node* - Essential for tiered *Lock** operations.
Airtable** - Acts as the central "Business Rules Engine."
Google Drive & HubSpot** - For storage and CRM synchronization.
OpenAI/Claude API** - For document classification and risk assessment.

🚀 Benefits
✅ Zero Manual Security Setup - Documents are locked according to corporate policy the moment they are uploaded.
✅ Regulatory Compliance - Meets strict GDPR "Right to be Forgotten" and data localization standards automatically.
✅ Proactive Risk Management - High-liability clauses and auto-renewals are flagged instantly to the legal team.
