Report #74297

[architecture] State corruption when multiple agents read/write to a shared memory blackboard concurrently

Implement Event Sourcing or Append-Only logs for the shared agent state, combined with vector clocks or sequence IDs, rather than allowing agents to mutate a single shared JSON state object.

Journey Context:
A common multi-agent pattern is a shared scratchpad \(blackboard\). If Agent A and Agent B read the state, update it, and write it back simultaneously, last-write-wins destroys state. Using an append-only event log means agents read the current state by folding the log, and write new events without overwriting history. Tradeoff: increases memory size and read complexity, but guarantees state recoverability and prevents race conditions.
