 ### 1.4 Remaining Vtable Stubs
 
-These vtable slots are stubs or partial implementations:
-
-| Slot | Purpose | Needed For |
-|------|---------|------------|
-| `overlay_draw_*` | Pixman animation buffer | Iconify zoom animation |
-| `client_snapshot` | Window thumbnail capture | Switch panel thumbnails, icon preview |
-| `window_set_border` | Scene rect border nodes | Window borders |
-| `client_synth_configure` | XDG configure scheduling | Resize negotiation |
-| `pointer_change_grab` | Grab parameter update | Menu tracking |
+| Slot | Status |
+|------|--------|
+| `overlay_draw_*` | ✅ Done — real pixman overlay implementation |
+| `client_snapshot` | ❌ Stub — needs last-committed texture → RImage |
+| `window_set_border` | ✅ No-op (borders drawn into frame buffer) |
+| `client_synth_configure` | ✅ Done — XDG configure + XWayland configure |
+| `pointer_change_grab` | ⚠️ No-op — menu tracking may need this |
