Lead qualification rules engine

Auto-qualify · scored 0–100

• +30 if budget ≥ 95% of listing rent
• +20 if preferred move-in within 45 days
• +15 if a company is provided (commercial signal)
• +10 if the scan device is mobile (in-person intent)
• +10 for each amenity match in notes
• −25 if scan is flagged as suspicious traffic

Threshold ≥ 55 → status qualified · ≥ 80 → alert manager instantly.

Bot & fraud heuristics

• Rolling rate limit per IP (10 / 5 min)
• Repeat fingerprint scans in < 30s → suppress
• Known datacenter ASN ranges → flag
• UA + Accept-Language mismatch → flag
• Missing scan referer + zero mouse events → flag
