openai/gpt-chat-latest → A (5:1)

Side A adds substantial new functionality: a dedicated pairwise voting page, pair-selection logic that prioritizes bridging disconnected ranking components, in-place UI morphing after votes, canonicalized item ID parsing to fix Reddit URL inconsistencies, and extensive unit/integration tests. Side B mainly removes a large autocomplete/parser system in favor of a simpler paste-and-go flow and redirect, simplifying the UI but largely replacing existing behavior rather than adding lasting project capabilities.
