Side A fixes canonical ontology path handling by introducing a shared `tilde_http_path_to_canonical` conversion, normalizing storage keys for the `~/` root, updating ranking lookups to use normalized keys, and correcting root-page behavior, backed by extensive unit, integration, and browser regression tests. Side B adds a substantial Reddit background fetch worker with OAuth and rate limiting, but it is largely new feature infrastructure without end-to-end validation and includes a placeholder TODO, whereas Side A directly resolves correctness bugs in core routing and ranking behavior with durable normalization logic.
