### Constraints & Assumptions
- The system uses retrieval-augmented generation over permissioned documents.
- Human review may be used for feedback, quality control, or approvals.
- Access control must apply to both retrieved context and generated answers.
- The answer should be practical for an enterprise platform.
### Clarifying Questions to Ask
- Who are the reviewers and what authority do they have?
- Is human review required before every answer or only sampled?
- What permission model exists for source documents?
- Can generated answers contain snippets from restricted documents?
- What audit requirements apply?
