Why summaries lie by omission

A summary is a set of decisions about what not to say. That’s not a flaw; it’s the whole function. But it means every gist carries a hidden argument about what mattered — and the reader rarely gets to see it.

The interesting design question for Gist isn’t “how do we shorten this.” It’s “how do we make the omissions legible.” Placeholder body; the real essay lands soon.
