Resilient Event Ingestion

Resilient Event Ingestion prevents permanent data loss during authentication outages by automatically writing raw SDK events to S3 instead of dropping them when LaunchDarkly's authentication dependencies become unavailable. Features automatic failover (requests that would return 5xx errors are stored in S3 with 202 acknowledgment) and data replay once authentication is recovered. This is an infrastructure-level improvement available to all customers across all regions with no action required.
