Report #5116

[architecture] How do you preserve event causality when agents emit events out of order?

Attach vector clocks or version vectors to events so receivers can detect causality, concurrency, and stale reads; do not rely on wall-clock timestamps across machines.

Journey Context:
Wall clocks drift and reorder events. In a multi-agent system, Agent B may process an event from Agent A before A's earlier event arrives. Vector clocks track the happens-before relationship explicitly, letting receivers identify concurrent or out-of-order events. The operational cost is embedding a small vector in every message, but the alternative is subtle ordering bugs that are nearly impossible to reproduce.
