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