Side B introduces a substantial, well-tested architectural improvement: a composable url_rules engine/registry replacing ad-hoc string canonicalization scattered across path_types.rs, reddit.rs, etc., with clearer per-domain rules and broad test coverage plus a documented rebuild step. Side A is a solid, more surgical fix (deterministic tokens, prose URL linkification, code-fence guard) but is narrower in scope and lower-risk; both are good, but B's redesign has longer-lasting structural value despite touching much more code including many mechanical test updates.
