It's not Proxy.  Per the "Problem" solved by "Proxy" on the web site 
you found:

  "You need to support resource-hungry objects, and you do not want 
  to instantiate such objects unless and until they are actually 
  requested by the client."

That's definitely not the problem being solved.

I think the "Problem" desc for "Facade" is a good match:

  "A segment of the client community needs a simplified interface 
  to the overall functionality of a complex subsystem."

The interface is "simplified" by essentially removing the modification
methods.
