+### Round 3 (2026-07-24) — MESA BUILDS ON REDOX ✅
+mesa.pkgar produced (27MB); libEGL.so + libgbm.so staged. The historical hard
+blocker (Mesa EGL/DRI on Redox) is CLEARED. Five Redox port fixes total, all in
+the tracked recipe (durable):
+  1. EGL gate: `redox` in meson system_has_kms_drm (patch 08).
+  2. alloca: force-include alloca.h.
+  3. wayland-scanner: overwrite sysroot copy with host binary (exit 127).
+  4. CLOCK_MONOTONIC_RAW: relibc has none, and Redox CLOCK_MONOTONIC=4 (not
+     Linux 1) — collided. Fixed by disabling Vulkan swrast (greeter uses GL, not
+     Vulkan; Vulkan WSI was the only consumer) + collision-proof define.
+Next: full build assembles the ISO (mesa cached, + driver-manager [operator WIP]
++ redox-drm/qt/kwin/sddm) → boot QEMU virtio-gpu → SDDM prompt.
