~anthropic/claude-sonnet-latest → A (6:4)

Side A replaces an O(n log n) per-batch deque-truncation trim with a simpler append-only List + query-time cap, bumps the schema version for correct migration, and adds a dedicated test verifying the new capping behavior — a real correctness/performance fix to the storage layer. Side B adds a sizable new feature (pool-scoped voting) with broad signature changes across many functions, but includes no new tests for the added pool logic, leaving its edge cases (empty pools, duplicate items, next-pair selection) unverified despite the larger diff.
