# Platform Capability Matrix (MVP)

Date: 2026-02-12

| Capability | Windows | Linux X11 | Linux Wayland | macOS |
|------------|---------|-----------|---------------|-------|
| `supports_click_through` | false (disabled by product requirement) | false | false | false |
| `supports_transparency` | true | true | true | true |
| `supports_tray` | false (current) | false (current) | false (current) | false (current) |
| `supports_global_hotkey` | true (implemented) | false (current) | false (current) | false (current) |
| `supports_skip_taskbar` | true (target) | false (current) | false (current) | false (current) |

## Notes

- Current code applies real Win32 operations for visibility, top-most, and positioning.
- Click-through is intentionally disabled by current product requirements.
- Non-Windows targets currently use a no-op adapter with conservative flags.
- Wayland limitations remain an expected degradation in v0.1.
