+# A finger flick the shape Iris's phone delivers one, from
+# docs/bench/iris-phone-v2-2026-09-06.md and docs/IRIS_TODO.md's
+# "From the phone, 2026-09-06, 22:16": at 120Hz a flick reaches the app
+# as DOWN, one or two MOVEs and UP inside a few frames, with the
+# intermediate positions batched inside those MOVEs as historical
+# samples (~4ms apart, the touch digitiser's own rate) rather than
+# arriving as separate events. Each line here is one such sample, which
+# is exactly what `IrisViewPeer::on_touch_event` replays through the
+# sensors one at a time -- so the whole gesture is 20ms and five
+# samples, and the velocity has to come out of *those*.
+#
+# Downward (increasing y) on purpose: the screen opens pinned to the
+# newest end, so a flick the other way has nothing left to scroll to and
+# the fling clamps on its first tick -- a pass that would prove nothing.
+# Coordinates are physical pixels on a 1080x2424 surface.
