~anthropic/claude-sonnet-latest → B (6:4)

B delivers a real architectural improvement—offloading Reddit JSON payloads from the in-memory GlobalTree to a RocksDB-backed EntityStore and switching event-log loading to a streaming replay—backed by new tests (entity_store, event_log, state) that materially reduce startup RAM, a genuine lasting fix. A is a clean, well-scoped UI feature (clickable unpin icon reusing the existing set_garden_pin flow) with matching CSS and a solid browser test, but it's a much smaller, more contained change. B's patch is bloated with vendored crate boilerplate (duplicate Cargo.lock, README, RFC docs, unused examples) that is mostly noise, but the core server-side integration is a nontrivial, correct systems improvement that outweighs A's narrower scope.
