What it says
A post view's like and repost counts and its viewer state are from the same moment: the like count includes the viewer's own like exactly when viewer.like is set, and the repost count their repost exactly when viewer.repost is. So a client shows count - [viewer.like] + [shown liked]. Checked against the fake PDS (cairn#251) and once against the real network (cairn#258).
