Multi-instance and multi-pass review

What the exam expects

• Explain why a model reviewing its own output in the same session misses errors, and why self-review instructions or extended thinking do not fix it.
• Use a second, independent Claude instance (a separate session, reviewer subagent or separate API call) that receives only the artifact, the requirements and the criteria.
• Separate writers from testers, and scope a reviewer to correctness and requirement gaps.
• Add a verification pass that checks each finding and records confidence and evidence so findings can be routed.
• Use a separate evaluator instance with a rubric, and choose aggregation thresholds when several independent reviewers vote.

Key terms: self-review (the generating session checking its own work); independent review instance (a reviewer without the generator's reasoning context); verification pass (a step that confirms or drops candidate findings); LLM-as-judge (a separate instance grading output against a rubric); voting (running several reviewers and combining their flags).
