# daemon/ produces the veloxd binary and the veloxd_rpc static library it is built from.
# Owned by lane DAEMON. Wired in by PKG via add_subdirectory(daemon) in the root file,
# guarded on this file existing.
#
# Layering (CLAUDE.md §3): depends on velox::core and velox::proto. No Qt. The engine
# (velox::core) is not linked yet — it arrives when sched/ and the task glue land; this
# first drop is the RPC transport + dispatcher skeleton so the CLI and GUI have a real
# server to talk to.
