Part of the plot revolves around retrieving the missing master copy of a film cartridge that makes viewers lose all interest in anything other than viewing it.
Read-only caches will contain invalid data whenever the master copy of data held in the back-end array is rolled back in time or restored to an earlier array-based snapshot.
Have one person in charge of the master copy of something, and others propose changes (i.e., pull requests) where each contribution gets tracked and conflicts get resolved.
