+      # vkroots is deliberately NOT listed here. It is a real gamescope SUBMODULE, and
+      # flatpak-builder clones git sources with submodules by default — so it is already
+      # checked out at exactly the rev above (`git ls-tree <rev> subprojects/vkroots`), which
+      # leaves `subprojects/vkroots/.git` as a gitlink FILE. Declaring it again with
+      # `dest: subprojects/vkroots` made the extractor copy the bare mirror onto that path and
+      # die before any build command ran:
+      #   cp: cannot overwrite non-directory '.../subprojects/vkroots/.git' with directory
+      # Re-adding it re-breaks the whole flatpak. If the submodule ever needs to be pinned away
+      # from the gamescope rev, set `disable-submodules: true` on the source above and then
+      # declare ALL THREE subprojects explicitly — not one of them alone.
