A link is built by formatting that protocol's own linktemplate, and the
templates are rows in accessprotocols that a site can edit. So no scheme
is a fixed fact about the product, and writing one down as though it were
misleads whoever reads it next.
Two places did. The guest-grant docstring said the detail route resolves
"working rdp:// and vnc:// links", which is wrong for the row we actually
ship: VNC is com.realvnc.vncviewer.connect://{host}:{port}, the RealVNC
handler, not vnc://. And the protocol admin form offered vnc://{host}:{port}
as its placeholder, in the one screen where somebody authors a new template,
so the example contradicted the seeded data it sits next to.
Neither changes behaviour. _computer_access_links already reads the
template from the database and the frontend only ever renders the resolved
link, so nothing in the code assumed a scheme - only the prose did.
