What is escalation marking?
Escalation is what happens when markers can't be reconciled automatically. If two markers disagree beyond an agreed threshold, or a response is genuinely borderline, it's escalated to a senior marker or panel to make the final call.
Escalation is the safety valve on a multi-marker workflow: most responses are settled by resolution rules, and only the genuinely contested ones are escalated for a human decision. Synap includes an escalation role alongside provisional, moderating and back-reading in its marking workflow.
