In the One Rendering Tree seen from g**t**, twin Lepiter pages are created for the Lineup in f**W**.
A frame object is serialized to a f**W** HTML frame snippet on a federated wiki page with esm.html plus "SOURCE monkey" markup and starts a breadth first search (BFS) process on the list index card assigned to it.
The frame content is constantly updated and serialized live. See Live Serialization
We are dealing with 2 single rendering trees: one within g**t** and one within f**W**, connected by a Card as a Portal. See HOPP pattern and Object Has Two Public Billboards (requests/offers), Card as Two-Sided Form
