Faults reported4 / 5
A saved diagnosis run on a Cogentco-derived benchmark subgraph with injected faults.
RECORDED QUERY SEQUENCE
9 TURNSThe investigation stopped before r3.
WHAT THE RECORD SUPPORTS
r29 lacks a BGP origin for the same prefix that r3 discards. The Agent reported the missing origin and omitted the static route. This run documents incomplete fault coverage; the interaction between the two faults remains a hypothesis for a separate controlled test.
