121-line redox.patch replaces 229-line fragile Python heredoc. Covers: meson.build, src/meson.build, event-loop.c, connection.c, wayland-server.c with signalfd, timerfd, eventfd, MSG_NOSIGNAL, open_memstream, timerfd_settime, timerfd_gettime stubs. libwayland builds successfully. Greeter cascade through llvm21.
