InMemory Driver & PoppyDB

This page has been split into two focused documents:

• InMemory Driver — the embedded, in-process driver for unit tests and embedded applications (cfg.driverSettings().setDriverName("InMemDriver")): capabilities, caveats (including the on-disk format gap), and testing strategies.
• PoppyDB — the standalone, MongoDB-wire-compatible server for CI/CD, microservices and integration testing (java -jar poppydb-cli.jar --port 27017).
