Exception Gate

Software componentHuman OversightExperience & Human Oversightarc:ExceptionGate

An oversight gate that flags proposed decisions matching defined exception patterns, such as unusual amounts, high-risk users, rare scenarios, conflicting signals or policy exceptions, and escalates them to a specialist reviewer.

Responsibility. Escalates edge-case decisions that match exception criteria to domain specialists.

Also known as: Exception-based escalation, Special-circumstance escalation

Variant of Oversight Gate abstract

When to choose. Choose when certain case characteristics (unusual amount, rare scenario, conflicting signals, policy exception) warrant specialist judgement regardless of agent confidence or aggregate risk score.

Design guidance

SHOULD escalate only cases matching explicit exception criteria rather than all edge cases, concentrating scarce specialist time where it adds value.

Quantitative guidance

As stated by the sources; verify before use.

Exception escalations are assigned high priority and a specialist reviewer type; expert escalation workflow SLA <2 hours (Ref10.01).
