+## Platform design principles
+
+- Customer-authoritative identity, data, infrastructure, models and operating policy.
+- Durable business and execution state independent of queues and worker processes.
+- Least-privilege access for users, services, applications and integrations.
+- Replaceable inference through a logical model gateway.
+- Truthful degraded and failure states instead of simulated success.
+- Versioned, reviewable and recoverable applications, packs and platform changes.
+- Signed offline delivery for approved releases, models and capability packs.

 ## Reference architecture
 
 Users access a single TLS origin and authenticate through enterprise identity.
