Build-an-X workflow that produces a blameless post-mortem from an incident - captures the timeline (chronological event sequence with sources), root cause analysis (what + why, not who), impact (users / revenue / SLO debt), action items (with owners + due dates + measurable success criteria), and "what went well" (intentional). Per Google SRE: "Blameless postmortems are a tenet of SRE culture." Use after every user-visible incident, not just severe ones.
