# dasungd in FDS/OS

The controller for the user's grayscale Dasung Paperlike 13K is maintained as an
FDS Rust workspace member. It provides USB keepalive, reconnect/watchdog handling,
configuration, and a local control socket.

Use the [FDS integration and usage guide](../../docs/dasung.md) for build commands,
base packaging, native s6 supervision, Pi display configuration, and validation
limits. From the repository root, run `make dasung` followed by `make dasung-test`.
These targets do not operate the workstation's live monitor.

[IMPORT.md](IMPORT.md) records the source task and original input hashes.
[VALIDATION.md](VALIDATION.md) is the original workstation acceptance record; its
references to the original README and systemd installation are historical. The
FDS target uses the native s6 integration documented in the guide above. Pi boot
and corrected physical cold-start recovery are not yet verified.
