I spent a good chunk of time today reviewing the code and debugging one of the failing seeds -- as near as I can tell the assert is sound, and it's definitely suspicious that we're seeing duplicate values at this point. Where i left off tonight is a strong confidence that the root problem is a single shard returning the same "value" (w/count) multiple times.
My next step is to do the same debuging with some of the other seeds and see if i can find the same evidence of duplicate facet values, and look for a pattern in the seeds / requests that trigger this to try and figure out when/why/where these duplicate values are getting returned by shards.
(Assuming i'm correct, this is a legitimate code bug, that only surfaces in some situations (not sure when) but only causes an error with java assertions turned on -- w/o assertions the code will silently use the second value returned.)

> There have been two recent jenkins failures of TestCloudPivotFacet on both 5x and trunk with the same underlying cause...

> <p>Problem accessing /collection1/select. Reason:
> <pre> java.lang.AssertionError: Must not add duplicate PivotFacetValue with redundent inner value</pre></p>
> {noformat}
> ..digging through mail logs, it looks like there have been a handful of these errors on different branches and os, with and w/o nightly, since April 1st of this year.
> The two recent seeds i tried (on trunk and 5x) reproduce - details to follow.
