Apple shipped a Claude.md file bundled with the Support app

The v5.13 release of the Apple Support app included Claude.md, which was then removed in the subsequent 5.13.1 release.

The file was divided into two sections.

• The Chat - Conversational Support (Juno AI + Live Agents) section described AsyncStream-based real-time updates, no use of Combine, actor-based service providers, abstraction of Juno AI/live agents/dev mocks via ChatViewModelServiceProvider, Task bridging for CCChatKit callbacks, separation of .client/.agent/.assistant roles, use of MessageGroup to avoid SwiftUI ID collisions, and storage of ChatInfo in Keychain along with CachesDirectory/TemporaryChatTranscripts/.
• The SAComponents - Shared UI Component Library section covered UI-only component principles, UIContentConfiguration in UIKit and preset factories like .cel1()/.callToActionProminent(), auxiliary modifiers in SwiftUI such as platterBackground() and frame(square:), static factories in Presets/, branching with #if os(visionS) and #available, documentation in SAComponents.docc/, and the requirement of #Preview {} for new components.

In other words, Apple included in its release a Claude.md file containing guidance on the Support app's chat support stack and shared UI components, then removed it in 5.13.1.
