> She might honestly believe she was treated in a specific way because of her sex
Yes, but the investigation said there was no evidence for a hostile work environment. That's a claim above and beyond sexism: it's quantifying over all of the various ways a work environment could be hostile (of which sexism is one way). If what Horvath says about Preston's wife is true, then that sounds like a hostile work environment to me, regardless of whether the treatment was due to her sex.

No, its not. "Hostile work environment" is mentioned as one of the legal violations it found to be unsupported, and "hostile work environment" is a legal term of art in sexual harassment law. In context, then, it is not a claim "above and beyond sexism", its is a claim about the absence of a particular form of sexual harassment.

You are reading it backwards: the finding of no legal wrongdoing, in the context of the allegations made of sexual harassment, is quantifying over all the various ways in which sexual harassment law could be violated, and the "hostile work environment" statement is one specific example of areas where sexual harassment was not found.
