The problem: My parents and family keep getting increasingly sophisticated scam messages—fake traffic violation notices with convincing phishing links, AI-generated videos, "digital arrest" calls. They're not careless; the fakes are just good now.

Targets ~2-4 second response time for new content, sub-second for cached. The tricky part was balancing false positives—flagging legitimate content as fake would destroy trust faster than missing actual scams.

Would love feedback, especially on detection edge cases. Happy to answer questions about the architecture.
