Strong framing. One extra boundary that mattered for us was separating “event received” from “business action authorized.” We store the raw event, derive a stable incident/workflow fingerprint, aggregate within a short window, and only then emit one idempotent command. That command carries its evidence, retry count, and CRM target, so a burst can be replayed without duplicating tickets or outreach.

While building Atlantic we learned that dedupe alone is not enough: you also need a DLQ for malformed events and an audit trail that explains why 200 inputs became one action. Otherwise aggregation fixes cost but makes debugging harder.
