Comprehensive audit of every dialog in tlc — render path, button
source, shadow source, hotkey consistency. Verifies the Phase 16-18
work brought 44/46 dialog surfaces onto the unified render_popup
path (33 filemanager + 5 editor/render + 1 ops/progress), with MC
rounded borders + drop shadow + skin-driven palette inherited
automatically.
Identifies the remaining 7% (the four high-priority items in §17.4):
P1 (HIGH) widget/dialog.rs:194 — Dialog::render uses raw Clear +
own Block instead of render_popup, so Dialog::info / confirm /
confirm_all render flat-border popups with NO drop shadow.
Only shadow regression in the unified stack. ~5-10 LOC.
P2 (HIGH) filemanager/overwrite_dialog.rs:138-181 — hand-rolled
Y/N/All/Skip/Abort colored Span legend. Single most visually
inconsistent button strip in the codebase. Migrate to
render_button_row of 5 ButtonSpec. ~25-40 LOC.
P3 (MED) filemanager/confirm_dialog.rs:186-191 — '[ Save ] [ Cancel ]'
Paragraph with theme.hidden. Migrate to 2-button row. ~8-15 LOC.
P4 (MED) editor/menubar.rs:520 — F9 dropdown still uses hand-rolled
Block + Clear instead of render_popup. Filemanager menubar
dropdown was migrated (c032c9a787); editor was not. ~5-10 LOC.
Plus lower-priority items:
P5 editor SaveBeforeClose Y/N/Esc legend migration
P6 viewer/editor SaveBeforeClose unification
P7 (optional) ~15 decorative key-legend hints migrated to
ButtonKind::Narrow rows
§17.3 documents the intentional non-targets (full-screen TreeDialog,
F9 menu-bar top rows, viewer render_prompt_overlay) so future
auditors know not to migrate them.
§17.5 codifies the three hotkey patterns (Action OK/Cancel,
Yes/No confirm, Yes/No/All/Skip confirm) and the locale keys
that drive them.
§17.6 sets the acceptance criteria: after P1-P4, grep for raw
Clear should return 5 sites, all defensible. Zero shadow
regressions. Zero hand-rolled button strips that look like
real buttons.
Tests: 1180 passing, 0 failing (no code changes, audit only).
Red Bear OS
A microkernel operating system written in Rust, derived from Redox OS
What is Red Bear OS?
Red Bear OS is a general-purpose, Unix-like operating system with a microkernel architecture, written in Rust. It is a full fork of Redox OS, frozen at release 0.1.0, with added hardware support, filesystem drivers, and a KDE Plasma desktop path.
Goals:
- AMD & Intel parity — first-class support for both platforms on bare metal
- KDE Plasma desktop — Wayland-based desktop environment via the KWin compositor
- Hardware GPU acceleration — AMD GPU (amdgpu) and Intel GPU drivers via
redox-drm - Modern subsystems — USB, Wi‑Fi, Bluetooth, ext4, GRUB, D-Bus
- Offline-first builds — reproducible from archived, BLAKE3-verified sources
Quick Start
Prerequisites
Linux x86_64 host with Rust nightly, QEMU, nasm, and standard build tools.
See the Redox Build Guide for full setup.
Build & Run
# Clone
git clone https://gitea.redbearos.org/vasilito/RedBear-OS.git
cd RedBear-OS
# Recommended: use the Red Bear wrapper
./local/scripts/build-redbear.sh redbear-mini # Text-only target
./local/scripts/build-redbear.sh redbear-full # Desktop-capable target
# Boot in QEMU with the resulting image
make qemu
Build script:
local/scripts/build-redbear.shis the canonical entry point. Baremake allworks but bypasses the.configchecking andREDBEAR_ALLOW_PROTECTED_FETCH=1gates thatbuild-redbear.shenforces. SeeAGENTS.md§ Build Commands for full details.
Public Scripts
| Script | Purpose |
|---|---|

Config Targets
| Target | Type | Description |
|---|---|---|
redbear-full |
Desktop | Wayland + KDE + GPU drivers + D-Bus services |
redbear-mini |
Console | Text-only recovery / install target |
redbear-grub |
Console | Text-only with GRUB boot manager |
Current Status
Red Bear OS boots to a login prompt in QEMU with working wired networking, D-Bus system bus, hardware detection daemons, and filesystem support (RedoxFS, ext4, FAT).
| Area | Status |
|---|---|
| Boot (ACPI/x2APIC/SMP) | ✅ Bare-metal proven |
| Userspace drivers (PCI, storage, net) | ✅ Working in QEMU |
| D-Bus system bus + services | ✅ Working (login1, PolicyKit, UDisks, UPower) |
| ext4 / FAT filesystems | ✅ Compiles, installer-wired |
| POSIX gaps (relibc) | 🚧 Bounded Wayland-facing support |
| DRM/KMS display drivers | 🚧 AMD + Intel compile; HW validation pending |
| Wayland compositor | 🚧 Bounded proof; Qt6/KF6 clients crash at init |
| KDE Plasma desktop | 🔄 In progress (Qt6/KF6 compile; KWin/QML blocked) |
| Wi‑Fi / Bluetooth | 📋 Planned (architected, implementation pending) |
How It Works
Red Bear OS uses a userspace driver model — all drivers run as unprivileged daemons:
Kernel (microkernel)
└── schemes: memory, irq, event, pipe, debug
└── Driver daemons (userspace)
├── pcid → PCI enumeration
├── e1000d → Intel ethernet
├── xhcid → USB controller
└── vesad → Display framebuffer
The kernel provides minimal services (memory, interrupts, IPC). Everything else — filesystems, networking, graphics, input — runs in userspace.
