wiki: 2026-11-10 afternoon refresh - first real GPU readback; direct-GL/window walls
Refresh STATE-CURRENT, the Main Page and the status/frontier pages: the DDX
3D replay executes and a guest pbuffer glClear+glReadPixels returns a red
pixel (ff0000ff); the RM write-lock holder (Xorg in the DDX scrub wait) is
fixed in df6e71bb. The direct-GL client channel still emits only setup/notify
kicks (ops_runs=0), a window draw wedges X, and X startup/RM stability plus
the DDX 4 GB sysmem allocation remain. Published to open-iov.org.
