Atlas answers advisor questions over its 2.4 million documents with cited sources. One workflow step decides whether a drafted communication to an EU client should be blocked for GDPR risk before it is sent. Using reversibility, stakes, and accountability as the justification, who should own this decision?

1. AA human reviewer, because sending a non-compliant message is hard to reverse and requires someone accountable for the call.
2. BClaude, because it drafts compliant EU communications reliably given its hybrid-retrieval and citation grounding every time.
3. CThe compliance rules engine, because GDPR risk categories are already deterministic and defined outside Claude entirely.
4. DWhichever component finishes evaluating the draft first, because speed matters most under the p95 latency SLA.
