## Current State
- `config/wayland.toml` exists — now uses the Red Bear runtime-service fragments and launches the
`smallvil` path by default via `orbital-wayland`
- `config/wayland.toml` exists — it remains the bounded validation path that launches the
`smallvil` harness via `orbital-wayland`, not the production desktop path
- 21 Wayland recipes in `recipes/wip/wayland/` — most untested
- `libwayland` 1.24.0 now rebuilds with a much smaller `redox.patch`; the P3 POSIX path (`signalfd`, `timerfd`, `eventfd`, `open_memstream`, `MSG_CMSG_CLOEXEC`, `MSG_NOSIGNAL`) is back on the native path, and the remaining patch is down to Redox-specific build quirks
- `smallvil` (Smithay) is still the recommended first runtime target because it is the smallest
compositor path already present in-tree
- `smallvil` (Smithay) remains the bounded validation compositor path, not the production desktop goal
- `cosmic-comp` builds but still has no working keyboard input; the remaining issue is runtime/input integration, not simply the absence of a libinput recipe
- `libdrm` builds with amdgpu and Intel enabled
- Mesa builds with EGL+GBM+GLES2 (software via LLVMpipe; hardware acceleration still requires kernel DMA-BUF)

For the first runtime-validation pass, keep the **runtime target** intentionally small: `smallvil`
as the compositor and no heavier secondary Wayland stack as the primary goal. The current
`redbear-wayland` profile still inherits the broader desktop package set from `desktop.toml`, but
Phase 4 validation in this repo is specifically about the `orbital-wayland``smallvil` path,
not about treating every inherited desktop package as part of the Wayland validation surface.

### Recommended: Smithay/smallvil first, then KWin
### Historical staging note: smallvil before KWin
**Why Smithay first:**
This section is historical context only. It explains why `smallvil` was used earlier as a bounded
validation compositor before the KWin-first production path became the repo's architecture.
**Why smallvil was used first as a validation compositor:**
- Pure Rust — no C++ toolchain issues
- Already has a Redox branch (`https://github.com/jackpot51/smithay`, branch `redox`)
- Smithay's input backend is pluggable — write a Redox-specific one
- Gets us a working compositor months before KWin is ported
- Provided an earlier bounded compositor proof before the KWin session path was viable
**What to modify in Smithay:**
