v2-ci / unit-tests (push) Has been cancelled
test(galaxy): #872 pin the detected_by rule per source
The rule fix itself landed in 1a08b4f7 (detail-0 failure rows route on
category); its test only exercised raw_detected_by = 3. Add per-source
coverage for every MxStatusSource value mxaccessgw's MapSource emits
(-1, 0..5, and an out-of-range value) across the failure categories, plus
the live-captured shape the old rule got wrong (OperationalError detected
by the responding automation object, mxaccessgw docs/AlarmProbeFindings.md)
and a RequestingLmx CommunicationError positive control. All 10 new cases
fail against the old 'detail 0 && raw_detected_by != 0 => comms' rule.

Comment in FromMxStatus now cites MapSource and says why NMX (2/3) is not
a transport signal. Item 1 (Warning/Pending) stays open pending a capture.
