Side B fixes a real correctness bug (silently defaulting to 0 instead of failing when an ingested post can't be found, and inconsistent 1-vs-0 indexing across garden.rs, rpc.rs, and types docs), consistently updates all affected call sites, and adds integration tests asserting correct index values. Side A only adds a new CLI display helper for existing stats with unit tests, which is useful but a smaller, purely additive feature rather than a fix to an existing defect.

A adds a complete, tested user-facing feature that surfaces existing ConnectivityStats (density, components, comparisons-to-connect) in pair CLI output, directly aiding voting decisions. B only tightens rank-history indexing (drop unwrap_or(0)/1-based map, always emit 0-based links, assert in tests)—a useful consistency fix, but narrower and less product leverage than A’s topology guidance.
Side A adds a new user-facing capability by exposing graph connectivity statistics in CLI pair output, including density, component count, connection status, and dedicated tests covering connected and disconnected cases. Side B mainly tightens an invariant by replacing fallback values with `expect`, aligns documentation and UI around 0-based thread indices, and adds assertions, but it is largely a consistency/refinement change rather than a substantial new feature.
