FICTIONAL HANDOFF
Harbor Shop buys service from Cedar Communications, which uses a hosted platform
and upstream network supplier; a separate ISP serves the shop. Inbound calls fail
while outbound calls work. The shop opens one case with Cedar and provides private
call timestamps, directions and scope. Cedar coordinates the investigation and
names the next action/update time. These names and events are invented.

LIVE CASE RECORD
