1. Validate config and secrets
Check required environment values, route settings, and secret availability before model serving starts.
A stable runtime starts with a strict startup order.
Startup flow
Operator: What is the first check?
System: Validate configuration and secrets before any serving starts.
Operator: What happens next?
System: Initialize the serving substrate, then enable orchestration and policy routes.
Operator: How do we know it is safe?
System: Observe health, logs, and contract behavior while iterating safely.
2. Initialize serving and runtime substrate
Bring model-serving components and shared-state runtime online before exposing orchestration entry points.
3. Enable orchestration and policy routes
Activate primary and fallback routing only after health checks confirm route viability.
4. Observe and iterate safely
Use logs, health signals, and contract validation to tune behavior without destabilizing production paths.
