Report #29723

[architecture] Concurrent agents overwrite shared state causing race conditions

Use an append-only event log or shared scratchpad with namespaced keys per agent, rather than allowing agents to mutate a single shared global state object directly.

Journey Context:
When multiple agents operate on the same task, they often read and write to a shared dictionary or global variable. This leads to race conditions where Agent B overwrites Agent A's update. The fix is treating inter-agent state like event sourcing: agents append their findings \(e.g., agent\_A\_findings: ...\) or use Compare-and-Swap \(CAS\) semantics. Append-only logs preserve history and prevent destructive overwrites.
