Side B makes a real architectural change: it introduces a RocksDB-backed entity store, replaces in-memory JSON storage with disk-backed storage, and switches event-log loading to a streaming replay to cut startup RAM, all wired through reducer/state/reddit modules with tests updated accordingly. Side A is a small, sensible but low-stakes config simplification (collapsing two kaocha suites into one glob pattern) that saves future test-registration effort but has negligible functional impact compared to B's storage/performance redesign, despite B's diff being noisy with vendored lockfiles/docs.

B adds a durable RocksDB-backed entity store, streams event-log replay so startup does not hold the whole log in RAM, and removes bulky Reddit JSON from GlobalTree—core runtime architecture. A only rewrites tests.edn ns-patterns to a single auto-discovered suite, a small config convenience with no product behavior change.

Side B introduces substantial new functionality: a RocksDB-backed durable storage crate, a new `EntityStore` that moves raw entity JSON out of in-memory state, and a streaming `EventLog::replay` API that replays events line-by-line instead of loading the entire log into memory, with corresponding integration changes across the server. Side A is a useful maintenance improvement that replaces hand-maintained Kaocha namespace lists with a single auto-discovered `^test\..+` suite, reducing future configuration work, but its impact is much narrower.
