Mentions = sampled opinion posts about OpenCode on that use-case page. Positive, mixed and negative are counted per point, not per post: they show the posts behind its recurring praise, disputed ("Split") and criticism points. One post can back several points, so these need not add up to the mentions, and the same post can appear under more than one use case. Positive, mixed and negative posts all count toward our feedback threshold.
