Side B ships substantial, functional code: cookie-based web session auth, a new /post web-ingest endpoint, room-scoped thread views/routing, and updated router wiring—real, working features that expand the product surface. Side A is valuable but purely documentation alignment (DSL.txt/GUIDE.sorter/plan.md wording fixes) with no functional change, and Side B is weakened somewhat by including an unpolished 'plan2.md' AI-chat transcript as noise, but its actual Rust/routing changes still represent more durable, load-bearing functionality than the doc-only patch.
