Report #82030

[architecture] Agents assume shared state has updated implicitly, acting on stale data due to eventual consistency delays

Use explicit state synchronization checkpoints where agents must read the latest state from the source-of-truth immediately before taking a mutating action.

Journey Context:
In asynchronous multi-agent setups, Agent A writes to a vector store or DB, and Agent B acts on it. If B reads before A's write propagates, B operates on stale state. Developers treat agent memory like local variables. The fix is to treat agent reads like database transactions: implement a read-before-write checkpoint where the agent explicitly pulls the latest state version, rather than relying on the context passed in the initial prompt.
