Checklist

• Line length ≤ 140 characters

• Protocols end with Contract
• Protocol types use any (e.g., any TrackerContract)
• Mocks end with Mock (suffix only, never prefix)
• Mock variables also use Mock suffix
• No force unwrap (!)
• Pattern matching: case let before the pattern, not let inside each binding
• No unused variables/parameters
• Code organized: properties → init → public methods → private extension
