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.
