brailyle'u is not a valid lujvo. You can't have a fu'ivla and a gismu as a veljvo. In that case you'll have to use "zei".
Actually, {braile} being of the form CCVVCV is one of the forms to which (even) the CLL assigns what it calls a fu'ivla rafsi. Maybe you recall the example of {tci'ile} that it uses to demonstrate a use-case of this proposal?
Regardless, as selpa'i mentioned, the PEG gives a rafsi to *every* fu'ivla (even {.irci}, for example). That being said, we could create a lujvo for "irc bot" {.irci'yzmi}.
