1. Architectural Principles

Zero-loss telemetry guarantees that all events dispatched from edge nodes are received, validated, and acknowledged without data drop, even during upstream network partitions.

Each payload is cryptographically signed using an HMAC-SHA256 signature to prevent tampering and replay attacks.

2. Backpressure & Dead Letter Queues

When ingestion throughput spikes beyond predefined threshold limits, edge connectors buffer payloads locally and apply exponential backoff with jitter.

Malformed events that fail schema validation are routed to quarantined dead-letter queues with complete contextual audit trails.
