The Groups card still called sharing "the upcoming sharing feature". It has
shipped — memory_visibility, groups, user_groups and project_shares are all
live — so the card now describes what group membership actually does:
read access for member groups, write access for read-write groups.
Authored on the fix/memory-list-project-filter branch on 2026-07-05 and never
committed; that branch is otherwise fully merged via PR #7.
