Cookbook

One task per recipe, each with a complete example, the reason it works, and links into the module pages. To build a whole game rather than one feature, start with the Workspace overview, which walks the design, plan, scaffold and build pipeline these recipes plug into.

Conventions that hold on every page:

• Examples are game code in the Game layer. Server systems are services in src/Server/Game/Services/, listed in src/Server/Game/Registry.luau; client systems are controllers in src/Client/Game/Controllers/. kernel is the kernel a service or controller receives in init, and short snippets call it Kernel.
• Every game channel is declared once in src/Shared/Game/Channels.luau and reaches a system as self.Net. Kits declare their own channels.
• Everything a recipe creates has an owner: a session (session:bind), a scope (kernel:createScope()) or the service’s stop. Timers are Scheduler deadlines, and continuous work runs only while something needs it. None of the examples poll.
• Recipes that depend on services Studio cannot fully exercise (DataStores, MemoryStores, MessagingService, teleports, bans, badges, real purchases, real latency) carry a Status note: what the specs and regression runners prove, and what still needs a published place.
