The argument lost to a collision: zellij speaks the same KDL syntax under that same extension with a different schema, and to anyone arriving from there .kdl said *whose* file it is -- naming the wrong owner is worse than not naming the parser. So a layout is x.layout, a project's is slosh.layout, the name says what the file is and --check says how it was read. (It is still KDL underneath; point your editor's highlighting at *.layout.) Nobody's checked-in workspace vanishes on upgrade: the project scan still finds slosh.layout.kdl, never writes it, and where both spellings exist the new one wins, because two files disagreeing needs one answer. The unparseable-file heuristic in --check learned the new suffix -- it matched '.layout.' with a trailing dot, which the new name no longer has. The webdemo overlay moves with it (demo.layout), rebuilt and boot-checked.
