test_gem300_scenario.cpp drives EquipmentDataModel in-memory. This
companion test does the same lifecycle through actual hsms::Connection
frames on a loopback socket pair:
S1F13/F14 establish comm
S3F17/F18 carrier action ProceedWithCarrier (E87)
S16F11/F12 process job create (E40)
S14F9/F10 control job create (E94)
S16F27/F28 CJSTART → CJ → Executing
S6F11 ControlJobExecuting CEID auto-emitted on transition
CJ → Completed via internal AllJobsComplete
EquipmentEmulator owns the data model + a passive Connection,
registers state-change handlers that synthesize S6F11/S16F9 on
transitions, and dispatches the inbound primaries above. HostEmulator
wraps the active Connection and captures everything the equipment
sends unsolicited.
This is the wire-level equivalent of the existing in-memory scenario,
which closes the gap between "FSM works" and "full GEM 300 stack
works on a wire".
Closes#10 in the test-gap backlog.
