You are right that the new Cowork should not carry a History pane. The page
lists it under "Thành phần bị dời chỗ": History, pane giữa, chỉ ở tab Cowork →
Sidebar ▸ RECENTS. Its own complaint about this screen is that three panes
squeezed the conversation under 60% of the width, and the wireframe draws two
columns — transcript and files.
But the same page also keeps the pane's chevron ("Pane Lịch sử: chevron trên
đầu History, gập thành dải mỏng — giữ"), and RECENTS ends in "Tất cả project…",
which opens it. So it is folded, not gone: search, filters, pin, rename and
multi-select delete only exist in that panel and deleting it would take them.
Cowork now opens with History folded to its 18px strip. "Tất cả project…" opens
it to 240px, and either choice is remembered — leaving the screen and coming
back no longer re-folds a panel you just opened, or re-opens one you just shut.
check_cowork_screen requires the fold on arrival and the strip to open on
request; restoring the old auto-expand fails it.
23/23 checkers pass.
