Struct MemoryTransactionStore 

pub struct MemoryTransactionStore { /* private fields */ }

Process-local reference backend for state-machine and concurrency correctness.

The lock covers only short record operations; virtual execution never occurs while it is held. Production runtimes use FileTransactionStore for crash durability.
