Known Gotchas
- ⚠ PRIVACY+CONSENT: Conversation recording and analysis requires explicit participant consent
- ⚠ No public MCP server — REST + WebSocket API
- ⚠ Real-time analysis uses WebSocket streaming — different protocol than async REST

- ⚠ Async processing requires polling or webhooks for job completion
- ⚠ US data residency only — may not meet EU data localization requirements
