Drafts are not routable: validate one with `POST /private-endpoints/{id}/validate`, then activate it with `POST /private-endpoints/{id}/activate`. Pass `activate` to do all three in one call; if validation fails the draft is kept and returned with the failed checks. Send an `Idempotency-Key` header to make retries safe: a repeated key with the same request returns the endpoint the first request created; reusing it with different fields returns 422 `idempotency_key_reused`. Returns 400 `parameters_invalid` when `tool_choice` is declared without `tools`. The response does not echo `declared_parameters` or `tested_parameters`; read them with `GET /private-endpoints/{id}`.
