src/SIL.LCModel/DomainServices/AnalysisGuessServices.cs line 707 at r1 (raw file):

			if (Cache.ServiceLocator.GetInstance<IWfiWordformRepository>().TryGetObject(tssWord, out wf))

			// Only create a lowercase wordform if there is an entry for it in the lexicon.

The comment is out of date. It should be "Only create a wordform if there is an entry for it in the lexicon".
