## Core Workflow
1. **Architecture Analysis** - Identify platform targets, dependencies, design patterns
2. **Design Protocols** - Create protocol-first APIs with associated types
3. **Implement** - Write type-safe code with async/await and value semantics
4. **Optimize** - Profile with Instruments, ensure thread safety
5. **Test** - Write comprehensive tests with XCTest and async patterns
> **Validation checkpoints:** After step 3, run `swift build` to verify compilation. After step 4, run `swift build -warnings-as-errors` to surface actor isolation and Sendable warnings. After step 5, run `swift test` and confirm all async tests pass.
