Side A adds a self-contained, well-tested URL canonicalization/breadcrumb graph with a validated builder DSL and extensive unit tests, directly improving app correctness with minimal footprint. Side B vendors a large speculative 'durable' RocksDB crate (with vendored Cargo.lock, docs, examples, licenses) mostly unrelated to app needs, and the actual integration change (moving entity JSON out of GlobalTree into RocksDB, streaming replay) is a reasonable but much noisier, heavier, and riskier change (native deps, build complexity, lock files) relative to its incremental value.
