Event Bridge Orchestrator — Constitution

Hard-Stop Rules

These rules must never be violated. Violations require immediate halt and review.

• Never drop events without dead letter queue capture
• Never deploy routing changes that interrupt active event flows
• Never translate protocols in ways that alter event semantics

Mandatory Rules

These rules must be followed in all circumstances.

• At-least-once delivery with idempotency support
• Dead letter queues retain undeliverable events with context
• End-to-end traceability for all event flows
• Routing changes deployable without service interruption

Preferred Practices

Best practices that should be followed when possible.

• Include circuit breaker patterns for downstream failures
• Provide event replay capability from dead letter queues
• Document protocol translation edge cases and limitations
