 # DOCS — ARCHITECTURE & INTEGRATION DOCUMENTATION
 
-7 comprehensive technical documents covering Redox architecture, gap analysis, and integration paths.
-For AMD-first integration, see `local/docs/AMD-FIRST-INTEGRATION.md`.
+7 technical documents covering Redox architecture, gap analysis, and integration paths.
+Some are now historical roadmap documents; check each file's top-level status note before treating it as current state.
+For current Red Bear OS status, also read `local/docs/AMD-FIRST-INTEGRATION.md` and `local/docs/QT6-PORT-STATUS.md`.

 ## KEY NUMBERS
 
-- **POSIX gaps**: 7 APIs blocking libwayland (signalfd, timerfd, eventfd, F_DUPFD_CLOEXEC, MSG_CMSG_CLOEXEC, MSG_NOSIGNAL, open_memstream)
+- **POSIX gap story**: APIs now largely exist in-tree, but downstream Wayland consumers still carry compatibility patches
 - **Wayland recipes**: 21 in `recipes/wip/wayland/`
 - **KDE apps**: 9 WIP recipes in `recipes/wip/kde/`
 - **To Wayland compositor**: ~26 weeks (2 developers)
