Commit A delivers a substantive architectural change—offloading large Reddit JSON payloads to RocksDB via a new durable crate and switching event replay to a streaming line-by-line model, both of which reduce startup RAM and are backed by tests—representing real, lasting infrastructure value despite the vendored crate bloat. Commit B is a solid but comparatively smaller refactor (vote-compare morphing via Idiomorph, pair-selection bridging logic, ItemId normalization) that improves UX and correctness but is narrower in scope and less foundational than A's storage/replay overhaul.
