What

• Part 5/7 of Code Backrooms Phase 4 (multi-file repositories): class lobbies. A class's methods used to crowd the module hub, one door each. Now a top-level class's methods that hang off the hub open off a lobby room (class UserService), which takes one door of the hub. More lobbies chain on past the door budget (m.ts//class:Svc#2). Methods reached by a call door keep that door, and returns still land at the module hub.
• The parser records class declarations as ClassNodes in CodeGraph.classes: id file.ts//class:Name (~2 on a repeated name, such as declarations in two branches), span, exported and topLevel. // can never appear in a normalised path, so a lobby id can't collide with any module.
• Hub planning moves to packages/code-graph/src/hub-plan.ts. parseHubId reads any hub id back as { module, classId, index }. roomSubject gives { kind: "class", module, node, methods } for a lobby.
• The HUD reads service.ts · class UserService, the door prompt reads → class UserService, and the source panel shows the whole class.
