"""
REAL WhatsApp Profile Discovery for Heritage Professionals
This script searches for ACTUAL phone numbers associated with heritage professionals,
then attempts WhatsApp discovery using those numbers.

PROCESS:
1. Extract person's name and institution from LinkedIn profile
2. Search web for phone numbers (business cards, contact pages, etc.)
3. For each found number, attempt WhatsApp discovery
4. Store REAL results only - no fabrication

WhatsApp Discovery Reality:
- WhatsApp requires PHONE NUMBERS, not names
- You add a number to contacts → WhatsApp checks if registered
- Profile visibility depends on THEIR privacy settings
- Cannot mass search - requires individual numbers
