Adaptive Overload Protection

Adaptive Overload Protection computes a rolling health score from request latency, queue depth, database saturation, and error rate. As the score degrades, CoreLink progressively sheds load: first deferring non-critical background jobs, then throttling bulk operations, and finally rejecting low-priority requests with a 503 and Retry-After header while preserving critical flows (authentication, audit log writes, break-glass unseal).

The overload dashboard visualizes the current health score, active shedding rules, and recent rejection counts by priority tier. Thresholds are tunable per tenant for SaaS deployments or per region for self-hosted clusters.

Key Configuration

• Health score component weights
• Shedding thresholds per priority tier
• Always-allowed critical paths
• Metric export interval
