~x-ai/grok-latest → A (3:1)

A adds a clean, targeted unit test that locks in core rank-centrality behavior (perfect-ratio spanning tree recovers alphabetical order), directly protecting a lasting invariant. B is a noisy “init seed” dump whose volume is mostly exploratory notes, scripts, and corrupted files (shell prompts and cat output embedded in forms.rs/ranking.rs), so far less durable substance despite the line count.
