View source for tense/modal is not equivalent to cu gotcha

You expect to be able to use '''pu''' in place of '''cu''' in front of a selbri to close the front sumti - right?  Wrong - if it's an abstraction!
{{mu|le nu mi klama pu vajni}}
is a sumti with parse:
{{mu|<nowiki>({le < [nu (mi {klama < [pu KU] VAU>}) KEI] vajni> KU} VAU)}}</nowiki>}}

*I don't. Sounds like someone mislearned that tenses mark the start of selbri.
*To be fair, the book says:
{{quotation|The placement of a tense construct within a Lojban bridi is easy: right before the selbri. It goes immediately after the '''cu''', and can in fact always replace the '''cu'''.|[[CLL]], (10.1, p. 216)}}
*Of course, it then goes on to say "(although in very complex sentences the rules for eliding terminators may be changed as a result)."
