~anthropic/claude-sonnet-latest → A (70:30)

Side A delivers a working, tested feature (RocksDB-backed entity payload offloading and streaming event log replay) with new module, real tests, integration test updates, and a genuine startup-RAM benefit; the vendored 'durable' crate is a real dependency addition despite the noisy Cargo.lock diffs. Side B is a large but purely mechanical rename/refactor (CanonicalItemUrl -> ItemId) that touches many files without adding new capability, and much of the diff is boilerplate churn plus deletion of a stale plan.md. A's change is more load-bearing (actual memory/behavior improvement) versus B's cosmetic-but-wide type rename.
