~anthropic/claude-sonnet-latest → A (9:1)

Side A implements a real feature: a working vote-compare morph flow, a new pair-selection module with bridge-priority algorithm and tests, storage-id normalization (from_storage), and integration tests plus test infra refactor (mock-reddit extraction). Side B is purely cosmetic rustfmt-style reformatting (import ordering, wrapping, if/else collapsing) with zero behavioral change, providing negligible lasting value beyond style consistency.
