Incident Owner Report - Bash Programming

A Bash incident remediation report can count visible incidents and assign the next owner from that count.
Program

Play the script to choose minimum severity and inspect the owner assignment.

visible incidents The severity threshold controls which fixed incidents stay visible.
owner assignment At least three visible incidents stay with operations; fewer move to lead.
fixed fixture The incident list is a fixed scalar string for deterministic replay.
