Axiom Icloud Drive Ref

A solid reference for file-based iCloud sync that covers the full stack from iOS 5's basics through modern APIs. This is for document-based apps that need to sync files across devices, not structured data (that's what CloudKit is for). It handles the practical stuff like ubiquitous containers, file coordination, and conflict resolution. Part of charleswiltgen's axiom collection, which has been getting decent traction. If you're building anything like a notes app or document editor that needs iCloud storage, this gives you the implementation details without having to dig through Apple's scattered documentation. Just know it's reference material, not a ready-to-go solution.
