A swipe that does nothing sends no request and throws nothing, so #383's freeze left nothing in the log or the traces, and the reader not scrolling was never found.

A swipe event per swipe in the reader: what it did (next, previous, back to the list, bounced at the end, too short, taken as a scroll), the position, loaded and total, under the tap's trace.
scroll_stuck: a drag up or down on an item that has room to scroll, and the reader did not move. Sends what could hold it: inert elements, the dialog, the reader's transform, #dpeek left behind, time since the app came back, the reader's sizes.
A dashboard panel counting swipes by outcome, beside the page's others.

Done in 5c1970e, deployed 2026-11-04 (ipx and ipx-web), and the iPX dashboard has a Swipes in the reader panel. Each swipe in the reader is logged as ev=swipe (msg: next, prev, list, end, short; state: position/loaded of total) under the tap's trace; a drag that should have scrolled the reader and did not is a warning, ev=scroll_stuck, whose state names what was under the finger, what was inert, the dialog, the reader's transform, #dpeek, and how long since the app came back. To look: {container="iPX"} |= "scroll_stuck".

On the Unread tab the page thinks there is more to load once its items are read #385
