Side A is a foundational architectural rewrite: it unifies the HTTP surface into a batched RPC API, separates room permission boundaries from forum thread tags in events/reducer state, and rewires the CLI plus integrations accordingly—lasting multi-tenant design rather than surface churn. Side B only improves the HTML pair-vote UX (in-place morph instead of redirect), extracts pair-selection helpers, and normalizes Reddit item IDs, which is useful but narrower and more UI-local.
