I read "chevron gập pane Lịch sử — giữ" as "keep it as a strip" and left an 18px
sliver down the side. The drawing has nothing there: the body row is two columns,
transcript and files, and the relocation table settles it — History (lịch sử
chat), was "pane giữa, chỉ ở tab Cowork", now "Sidebar ▸ RECENTS", verdict "giữ,
dễ tới hơn". The line about the chevron belongs to a tally of the app's eleven
collapsible spots, not to this screen's layout.
So the panel is not on Cowork at all. "Tất cả project…" in RECENTS brings it in
at full width — it has to stay reachable, because search, filters, pin, rename
and multi-select delete exist nowhere else — and its chevron puts it away again.
Either choice survives leaving the screen and coming back.
check_cowork_screen now requires it absent on arrival and present after the
request; showing it unconditionally fails.
23/23 checkers pass.
