Cnerium Documentation
A reliability-first backend layer for Vix applications.
Cnerium does not replace Vix. It attaches to an existing Vix backend and adds durable route behavior for critical write operations that must stay correct under retries, timeouts, lost responses, and unstable networks.

}Vix Integration
Keep Vix as the backend owner and attach Cnerium only where retry safety matters.
Durable Routes
Protect critical POST operations with stored responses, replay safety, and clear execution rules.
Idempotency
Use Idempotency-Key and request body hashing to distinguish safe retries from unsafe reuse.
Realtime Events
Emit application events from durable handlers without duplicating notifications on safe retries.
