Write an Incident Postmortem

$write-incident-postmortem

An incident can be resolved before anyone has proved why it happened. This skill applies the Incident Postmortems Specification to keep facts, reported claims, inferences, hypotheses, and decisions separate. It preserves real uncertainty, requires recovery proof, and moves corrective work into durable Engineering Follow-ups instead of a hopeful checklist.
