vdm/daemon/CMakeLists.txt

# daemon/ produces the veloxd binary and the static libraries 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
# drop is the RPC transports (Unix socket + loopback WebSocket), the SQLite store, and a
# dispatcher skeleton so the CLI and GUI have a real server to talk to.
