Defined in: [packages/common/src/local-first/Protocol.ts:461](https://github.com/evoluhq/evolu/blob/e7144e2bbe9069362b62dec1b64a8aa922b8f1b0/packages/common/src/local-first/Protocol.ts#L461)

Error when storage or billing quota is exceeded.

When relay rejects writes due to quota, the affected device stops syncing
because RBSR requires both sides to converge—if the relay won't accept the
client's data, they can never reach the same state. Only the device with
excess local data is affected. Other devices that haven't exceeded quota can
still sync normally.

Clients should prompt the user to contact the relay provider or upgrade their
plan. Quota monitoring and management is the relay provider's
responsibility.
