## Overview
This document maps the distance between current Redox OS 0.9.0 and three goals:
1. **Wayland compositor support** → see [03-WAYLAND-ON-REDOX.md](03-WAYLAND-ON-REDOX.md)
1. **Wayland compositor support** → see `../local/docs/WAYLAND-IMPLEMENTATION-PLAN.md`
2. **KDE Plasma desktop** → see [05-KDE-PLASMA-ON-REDOX.md](05-KDE-PLASMA-ON-REDOX.md)
3. **Linux driver compatibility layer** → see [04-LINUX-DRIVER-COMPAT.md](04-LINUX-DRIVER-COMPAT.md)

Sleep state transitions (`\_Sx` beyond `\_S5`) and sleep eventing are **known gaps**. DMAR module remains present in `acpid` but not wired; ownership is still transitional/orphaned rather than cleanly transferred.
