Use when working on Windows, Android, Linux, iOS, or macOS protocol implementations (pea-windows, pea-android, etc.). Follow the corresponding .tasks file (02–06); ensure wire format and discovery match pea-core and .tasks/07.
When working on a protocol implementation for a specific OS:
Reference the right .tasks file: .tasks/02-windows.md, .tasks/03-android.md, .tasks/04-linux.md, .tasks/05-ios.md, or .tasks/06-macos.md. Implement the checklist items; do not put platform I/O (sockets, VPN, proxy) inside pea-core.
Use pea-core as dependency: The implementation crate (e.g. pea-windows) depends on pea-core. Call into pea-core for protocol logic, chunking, scheduling, and integrity; the implementation handles discovery, traffic interception, and local transport.
Wire format and discovery: Keep the same wire format and discovery protocol as defined in pea-core and .tasks/07-protocol-and-interop.md. All platforms must interoperate (e.g. Windows and Android in the same pod).
Platform-specific mechanisms: Use the correct OS mechanism for traffic interception (e.g. system proxy or WinDivert on Windows, VPNService on Android, Network Extension on iOS/macOS). Document any platform constraints in the implementation or .tasks.
