The primary ``emsd`` task trees are:
The primary ``emsd`` task tree is:
- ``_setup_persistent_emsd()``:
is the ``emsd`` actor's primary root task which sets up an
actor-global ``Router`` instance and starts a relay loop task
which lives until the backend broker is shutdown or the ems is
terminated.

accept normalized trades responses from brokerd, process and
relay to ems client(s); this is a effectively a "trade event
reponse" proxy-broker.
- ``_emsd_main()``:
attaches a brokerd real-time quote feed and trades dialogue with
brokderd trading api for every connecting client.
|
- ``clear_dark_triggers()``:
run (dark order) conditions on inputs and trigger brokerd "live"
order submissions.

- ``process_client_order_cmds()``:
accepts order cmds from requesting clients, registers dark orders and
alerts with clearing loop.

is opened by the `pikerd` service manager and sets up
a process-global (actor-local) ``Router`` instance and opens
a service nursery which lives until the backend broker is

*dynamically* started (and persisted) within this service
nursery when the below endpoint context is opened:
