+**2026-09-08 (newest): nothing on the transcript is unbounded any more,
+and both APKs are new.** Rebuilt from ai-app-2 `afbc2ad`. This one has
+things to look at, unlike the last.
+
+**The edit-card lag you reported is fixed, and it was a framework bug.**
+Not text layout: shaping and rasterising a 51,200-glyph block is 20ms, and
+the frame that drew it took 1.37 seconds. Redrawing a widget frees every
+primitive it owned and writes fresh ones, and finding each one's handle to
+renumber was a scan of everything that widget drew -- so one redraw cost
+O(its own glyph count squared). It is 29ms now, and linear. Expanding a
+big card should feel immediate; if it still doesn't, that is a *different*
+fault and worth saying so.
+
+**Both apps now cap long things behind "Show all N lines".** Same rule and
+the same numbers in both, so this comparison is still renderer against
+renderer:
+
+- a tool call's **input** -- 80 lines or 4 KiB. This is the one you asked
+  for; an `Edit`'s `old_string`/`new_string` used to arrive whole.
+- a tool call's **output** -- same bound. iris already did this; the
+  Compose app didn't, and now does.
+- a **message**, yours or the model's -- 200 lines or 16 KiB.
+
+A reply still streaming is never capped, so watching one arrive is
+unchanged. A message is cut between markdown blocks rather than through
+one, so you should never see half a fence.
+
+**Raw text no longer wraps in the Compose app** either -- a tool's
+leftover input fields and its output pan sideways, the way the command
+line already did. Both apps agree now.
+
+Worth pressing: expand the biggest edit card you can find; press "Show
+all" on a card and on a long message and check the transcript doesn't jump
+under you; scroll a long output sideways.
+
+**2026-09-08: scrolling is one mechanism, and this build is
 mostly structure.** `iris-bench-arm64.apk` rebuilt from ai-app-2
 `4fdabc3`, four commits on from the last one. **There is deliberately no
 new feature here and little that should look different** -- it is the
