Side A implements a substantial new capability across the system: shareable room invites with OAuth redemption, room auditing, multi-capability grants, new RPCs/CLI commands, server routes, state handling, reducer updates, API/type changes, and integration tests. Side B is a focused UI improvement that makes existing pin icons in ranked child groups clickable to unpin, with corresponding CSS and browser test updates, but it is a relatively small usability enhancement compared with the new end-to-end functionality in Side A.
