Side A removes dead demo-counter code/tests and reworks the core vote pipeline into a real architectural improvement: votes are now committed and rescored via a dedicated async settlement worker with cached scores, and ranking_panel/home no longer take a write lock and recompute PageRank on every request. Side B adds a useful but narrower feature (pool-scoped vote pairs) that is well-contained but doesn't touch core state/performance design, making Side A's change more foundational and higher-leverage for the codebase.

council reasoning
A removes throwaway demo-counter scaffolding and adds a lasting settlement worker (batched append + ranking recompute, warm cache, read-only HTTP ranking path via ranked_items_cached), which hardens the core vote/ranking data path. B is a solid product slice (pool-scoped /vote and UI plumbing) but is incremental feature threading atop existing compare flow, not foundational architecture.
Side A introduces a substantial architectural improvement by separating ranking computation from cached reads, adding a settlement worker that batches vote persistence and score recomputation, warming the cache at startup, and switching UI rendering to read-only access for faster requests. Although it also removes the demo counter, the enduring value comes from the new cached ranking and asynchronous settlement design, whereas Side B primarily adds a useful but feature-specific pool-scoped voting workflow by threading an optional pool parameter through routing, navigation, and pair selection.

[5350388a] Add pool-scoped voting: /vote?pool=<parent> picks pairs from children. - /vote now accepts an optional `pool` param (parent item path). When provided without left/right, it picks the first unvoted pair from the pool's children. When provided alongside left/right, it constrains "next pair" navigation to siblings within the pool. - "vote on children" button appears on item pages with ≥2 children, linking to /vote?pool=<item>. - Pool is threaded through VoteComparePost → success JS so in-page morph after voting keeps the pool context for next-pair navigation.
