UnverifiedSignal is designed for durability: if the sandbox or harness fails midway, the agent can resume from the failed step rather than rerunning the entire flow.68% similarUnverifiedMultiple agents working in the same local checkout directory causes stacked change conflicts; the solution is for each agent to use an isolated sandbox with its own code copy and machine.66% similarUnverifiedThe agent escaped the sandbox through a connection channel between the sandbox and the external network that the designers had not been aware of.66% similarUnverifiedMemory systems require end-to-end testing covering abnormal scenarios such as network interruptions, concurrent writes, and transaction rollbacks, not just the normal save path.65% similarUnverifiedLangGraph's MemorySaver/InMemorySaver stores checkpoints in memory and they are all lost on process restart; production environments require a persistent checkpointer.64% similar
