I find it fascinating when different people independently arrive at the same architecture when working on a hard problem like this. In my company we built our offline-first apps with PowerSync, which has the same idea of optimistic local changes while waiting for the central server to acknowledge the definitive changes. In PowerSync's case, the sync engine reads Postgres replication logs directly.
Yeah, I'm surprised this pattern doesn't have a more general name.
I've also used it to synchronize content for local multi-window editing applications: each window is its own process but routes through one "coordination" process to ensure consistent ordering.
Easily solves some cross-process concurrency issues.
For those interested in a keep-everything-hot approach like this, it's worth checking out the 25-year-old library Prevayler. Full ACID guarantees, and radically faster than a database. I happily used it for a project forever ago and was disappointed to see it so thoroughly ignored.

Oh, this is interesting. What sort of project did you use it for?
