Report #79112

[frontier] Multiple agents working on shared documents cause conflicting updates and lost writes due to lack of causal ordering

Implement vector clocks \(Lamport timestamps\) per document: each agent maintains a vector of counters per agent ID, increments its entry on write, and merges vectors on sync. Reject updates with vector clocks that don't dominate the current state

Journey Context:
In collaborative agent systems \(e.g., multiple research agents editing a report\), naive last-write-wins causes data loss. The solution borrows from distributed systems: vector clocks track 'happens-before' relationships. Each agent has a unique ID. When agent A updates, it increments A's counter in the vector. When agents sync, they merge vectors \(take element-wise max\). If a new update's vector doesn't dominate \(>= all elements\) the current vector, it's a concurrent update that requires conflict resolution \(e.g., merge algorithm or human review\). This is standard in CRDTs but is only now emerging in agent orchestration as systems move beyond single-threaded execution. It's crucial for 'swarm' architectures where agents are truly parallel.
