wiki: 2026-11-10 morning refresh - X reliable, GR timeouts fixed; beef-ring/CB/RT walls
Refresh STATE-CURRENT, the Main Page and the status/frontier pages:
ebf3130f fixes the X DMA-init path and flips the GR pair-close/pair-safe
replay fixes default ON (X green on attempt 1 in three consecutive cycles,
backend_timeout=0, draws retire in 3-2400 ms); bb802909 is committed. The
replayed draw still writes 0 pages; the beef GR ring resolution, the
fixed-CB image's zero 0x80 MVP block and the render-target bind are the
named walls. Published to open-iov.org.
