The interface is only the first layer.
The Livara Nexus visualizes architecture as five inspectable layers. It is an explanatory model—not a claim that both products share one deployment or identical controls.
Experience layer
Bilingual, accessible interfaces expose status, boundaries and recovery actions. Important state remains readable in ordinary HTML and does not depend on animation.
- English and Persian
- DOM-first content
- Explicit empty, denial and recovery states
Realtime and offline continuity
Livara Chat documents persistent events and exact reconnect gaps. Dr. Livara treats offline operation as a safety-sensitive research area; offline chart editing is not approved or claimed.
- Product-specific reconciliation
- Stable operation identities
- No generic “always available” claim
Policy and service core
Identity establishes who is acting; policy determines which action is allowed. In Dr. Livara, role, tenant and facility scope are designed as separate inputs rather than presentation-layer switches.
Audit and observability
Operational logs help run software. Sensitive audit evidence has a different purpose and boundary. Dr. Livara describes a minimized tamper-evident audit ledger in implemented protected scopes, not a tamper-proof guarantee.
Isolated or protected data
Protection depends on the product and data type. Livara Chat message, group, channel and call content is end-to-end encrypted, while platform metadata and Dr. Livara tenant-scoped records remain separate boundaries that must not be collapsed into one promise.
