Engineering: Eliminating Telemetry with Edge Routing

Why proxy servers actively degrade user privacy and how immediate client-side API bridging repairs it.

The Proxy Anti-Pattern

Thousands of wrappers claim to be "secure", but route your prompt matrix through Vercel or AWS Lambda functions simply to hide their own API keys. This creates an un-auditable man-in-the-middle.

By requiring users to supply API vectors directly to their client boundary, Duplex forces direct `fetch()` commands directly to OpenAI or Anthropic load balancers, fundamentally cutting out the telemetry capabilities of a secondary entity.
