Privacy classes

MESH classifies every call into one of four privacy classes. The class controls upstream selection, logging behaviour, and the privacy block returned in the response. The router enforces the class — it cannot be silently downgraded.

{
  "model": "auto",
  "privacy": {
    "class": "protected_provider_route"
  },
  "messages": [{ "role": "user", "content": "sensitive prompt" }]
}

The legacy form is still accepted; mode: "mesh" maps to private_gateway_route and mode: "standard" maps to standard_route. New code should prefer class.

{
  "model": "auto",
  "privacy": { "mode": "mesh" },
  "messages": [{ "role": "user", "content": "private request" }]
}
