From 361d7d13842608aa7d7bd4cb187d540518bb09e3 Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Tue, 10 Nov 2026 06:05:01 -0500 Subject: 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.
