milestone: Phase 4-5 completion + KF6 honesty + KDE session + GPU CS ioctl

Browse Source 
Phase 4 KDE Plasma:
- 20 KF6 + kglobalacceld + plasma-workspace + plasma-desktop + plasma-framework enabled
- kf6-kio honest reduced build (package-local QtNetwork compat headers, no sysroot fakery)
- kf6-kdeclarative enabled
- redbear-kde-session launcher (DRM/virtual backend, plasmashell/kded6, readiness markers)
- Phase 4 checker: required plasmashell/kded6 process checks (FAIL on absence)

Phase 5 Hardware GPU:
- CS ioctl checker (GEM allocation, PRIME sharing, private CS submit/wait over /scheme/drm/card0)
- Enhanced GPU checker with hardware rendering readiness summary
- test-phase5-cs-runtime.sh harness

Qt6Quick honesty: qtdeclarative exports Qt6Quick metadata; downstream QML/Kirigami/KWin proof still insufficient.
Oracle-verified: Phase 4-5 (5 rounds).

Build: zero warnings.

# Red Bear OS Desktop Stack — Current Status
**Last updated:** 2026-04-29
**Canonical plan:** `local/docs/CONSOLE-TO-KDE-DESKTOP-PLAN.md` (v2.1)
**Canonical plan:** `local/docs/CONSOLE-TO-KDE-DESKTOP-PLAN.md` (v2.2)
**Boot improvement plan:** `local/docs/BOOT-PROCESS-IMPROVEMENT-PLAN.md` (v1.0)
**Source archival policy:** `local/docs/SOURCE-ARCHIVAL-POLICY.md` (v1.0)
## Recent Changes (2026-04-29, Wave 7)
- **KF6 surface made more honest for Phase 3/4**:
- `kf6-kdeclarative` is now enabled in `config/redbear-full.toml` because its tracked recipe is already a real reduced cmake build with `BUILD_WITH_QML=OFF`.
- `kf6-kio` is now enabled in `config/redbear-full.toml` as an honest reduced KIOCore-only build. The recipe no longer injects fake QtNetwork headers into the shared sysroot; instead it uses source-local Redox compatibility headers for the bounded `QHostAddress` / `QHostInfo` surface KIOCore still needs.
- `kf6-knewstuff` and `kf6-kwallet` were re-checked and remain stub-only recipes (dummy CMake targets + dummy archives), so they stay suppressed.
- Enabled count is now **20 KF6 packages + kglobalacceld**, with **3 suppressed** (`kirigami`, `kf6-knewstuff`, `kf6-kwallet`).
## Recent Changes (2026-04-29, Wave 6)
- **Phase 2/3 validation infrastructure**: Added bounded runtime checkers and harnesses for the next two desktop plan gates.
@@ -44,7 +52,7 @@
- **Qt Wayland shell integration**: Compositor correctly parses protocol now, but Qt6's Wayland plugin reports "Loading shell integration failed" and falls back to redox platform plugin. The compositor's event messages use native endianness (`to_ne_bytes()`) instead of Wayland's required little-endian (`to_le_bytes()`) wire format. Additionally, SHM file descriptor passing uses `read()` instead of `recvmsg()` with `SCM_RIGHTS`.
- **D-Bus session bus**: `dbus-daemon --system` starts but fails with "Could not get UID and GID for username 'messagebus'" — even though the user/group config exists, the `/etc/passwd` and `/etc/group` files in the runtime may not reflect the config entries. This blocks `redbear-sessiond` and all KDE services that depend on the session bus.
- **KF6 enablement**: 18 KF6 packages + kglobalacceld now enabled in redbear-full.toml (non-cascading subset). kirigami, kf6-kio, kf6-kdeclarative, kf6-knewstuff, kf6-kwallet remain suppressed (QML stubs, QtNetwork shims).
- **KF6 enablement**: superseded by Wave 7 — 20 KF6 packages + kglobalacceld are now enabled; `kirigami`, `kf6-knewstuff`, and `kf6-kwallet` remain suppressed.

Kirigami is stub-only (Qt6Quick not available on Redox). kf6-kio is heavily shimmed (QtNetwork disabled, KIOCORE_ONLY=ON). kf6-knewstuff and kf6-kwallet are stub-only. These collectively prevent plasma-workspace from building honestly, which blocks the entire KDE Plasma session.
Kirigami is stub-only (QML-dependent; qtdeclarative exists but downstream QML/Kirigami proof insufficient). `kf6-knewstuff` and `kf6-kwallet` are still

the KDE Plasma session. `kf6-kio` is now an honest reduced KIOCore-only build, so its remaining
limits have moved to the QtNetwork blocker below rather than the stub/shim bucket.
### 7. QtNetwork disabled blocks KDE network integration
QtNetwork is intentionally disabled because relibc networking is too narrow. This prevents Qt-based network applications, kf6-kio network transparency, and KDE network-dependent features.

The remaining work is **broader runtime validation, compositor/session stability, and the remaining KDE session/runtime proof work**.
Phase 1 (Runtime Substrate Validation) has comprehensive test coverage; the remaining gate is live-environment runtime validation. The key boundary for Phase 2 is: no compositor session proof exists. The key boundary for Phase 3-4 is: kirigami, kf6-kio, and QML dependencies must become honest before KDE Plasma session assembly can proceed.
