Design exercise: Hallucination & Failure Detection

Unsupported claims, citations, abstention, tool errors, constraint violations, uncertainty, and escalation. Implement designOutline() returning non-empty values for: evidenceCheck, constraintCheck, escalation. Each value must name a concrete mechanism or decision.

The mechanism

Detect failures against evidence and task constraints. Require citations where possible, validate structured claims, calibrate abstention, and route uncertainty to tools or humans.

Study Hallucination & Failure Detection

Expected evidence

A design outline with evidenceCheck, constraintCheck, escalation plus an explicit failure mode or trade-off.
