Conversations
WhatsApp and RCS sessions run on infrastructure that remembers the whole thread. Every prior message lives on the same layer that sent the original notification, not stitched together after the fact by a separate inbox tool.
Guardrails
Approve-first mode, tone and voice locks, and discount ceilings are enforced below the product layer with a full audit trail attached to every AI-generated message, the standard banks already hold every other system to.

Observability
