B is a tight, correct bugfix: it replaces timestamp-based feed cutoffs with ingest-position anchors (fixing same-millisecond races and clock rollback) and adds permission-aware room visibility, backed by focused integration tests proving the exact failure modes it fixes. A vendors an entire new 'durable' crate wholesale—including marketing README, RFC docs, motivation.md, multiple examples, and a duplicated Cargo.lock—so most of its bulk is generated/boilerplate noise, with the actual server-side change (entity_store.rs, streaming replay) being comparatively small and unproven by tests for the RAM-reduction claim. Per the rubric favoring precise, necessary fixes over diffuse churn, B delivers more verified, lasting correctness per line changed.

Commit A adds a full RocksDB-backed durable crate, moves Reddit entity JSON off the in-memory GlobalTree into entity_db, and streams event-log replay line-by-line, which is a lasting architectural fix for startup RAM and payload retention. Commit B correctly stabilizes feed catch-up on ingest order and hardens multi-user private-room visibility with solid tests, but it is a targeted correctness fix in one API path rather than a foundational storage redesign.
Side A implements substantial infrastructure changes: it introduces a RocksDB-backed `durable` workspace crate, moves raw Reddit entity JSON out of the in-memory tree into a persistent `EntityStore`, and replaces whole-file event loading with streaming replay to reduce startup memory while updating reducers and tests accordingly. Side B is a solid correctness improvement—changing feed catch-up to use durable ingest order instead of timestamps, enforcing room visibility during feed generation, and adding regression tests—but it is a targeted behavioral fix rather than the broad persistence and scalability architecture added in Side A.
