I've been working on figuring out the history of this bit of wording, since it's, on the surface, transparently untrue (we, in fact, do want to provide truth as well - not necessarily big-T absolute truth, but certainly the little-t truth that is a synonym for "accuracy" - i.e. the word as normal people use it).
Originally, WP: V explicitly called for accuracy: http://en.wikipedia.org/w/index.php?title=Wikipedia:Verifiability&oldid=... . The term was removed in a language tweak in 2005. The phrase "verifiability, not truth" came from a draft revision of WP:NOR in December of 2004.
As far as I can tell, there has *never* been a consensus discussion of the phrasing "verifiability, not truth," nor was there a discussion about removing the statement that Wikipedia strives to be accurate from WP:V. These changes were inserted, albeit years ago, without discussion, and long-standing principles were pushed to the side and minimized in favor of increasingly context-free restatements of the changes. But I cannot find *any* evidence that the position "accuracy is not a primary goal of Wikipedia" has ever garnered consensus.
Is anyone aware of a discussion to this end that I am not? Is there actually a point where we clearly and deliberately decided that the goal of Wikipedia is not accuracy?
