SwiftUI watch-only app in watch/, generated by XcodeGen. Codable models mirror gateway/src/contract.ts, with lenient string enums so new phases or decisions still decode. A DemoGateway serves fixtures from the docs/api.md examples for previews and demo mode. Swift Testing covers decoding the documented JSON, request encoding, notification action parsing and the small view helpers. Co-Authored-By: Claude Opus 5.5 <[email protected]>

// Fixture data shaped like the docs/api.md examples, served by an in-memory gateway. Demo mode and
|

// SwiftUI previews use it, so every screen renders without a live gateway. It reacts to writes:
|
|
// answering an approval moves the thread to working, a reply restarts a finished thread, and so on.
