Three things one pass over the shell's chrome turned up, none of them related to the others beyond having been looked at together. ◆ A PALE STRIP ACROSS THE TOP OF THE WINDOW ON WINDOWS, and it is not this application's titlebar. Avalonia's Win32 backend gives a BorderOnly window WS_BORDER | WS_THICKFRAME and then calls DwmExtendFrameIntoClientArea with one-pixel margins on all four sides — read out of WindowImpl.UpdateWindowProperties in 12.1.1 rather than guessed at. So DWM owns a hairline of every edge and fills it with the system's caption and border colours, which follow the user's personalisation settings: with "show accent colour on title bars and window borders" on, that is blue against a near-black shell. Nothing in the visual tree painted those pixels, which is why nothing in the visual tree could cover them. NativeWindowFrame sets DWMWA_BORDER_COLOR and DWMWA_CAPTION_COLOR to the window's own Background, so the hairline still exists — the resize grip is on it, the drop shadow hangs off it — and cannot be seen. Deliberately not DWMWA_COLOR_NONE, which removes the border outright and leaves a near-black window with no edge at all on a dark desktop. Windows 10 gets the dark-mode attribute and nothing else, because the two colour attributes are Windows 11 and DwmSetWindowAttribute simply answers E_INVALIDARG there. Called from OnOpened, not the constructor: there is no platform handle until the window is shown, and calling early is a silent no-op — which looks exactly like a fix that does not work. Verified on screen on Windows 11. ◆ THE HOSTS HEADER SAT A STEP LEFT OF AND ABOVE EVERY OTHER SCREEN'S. Keychain, Snips, Logs and Pins all frame their content with Margin="26"; Hosts was on 16 a side and 20 on top. It is 26 all round now, stated per row rather than once on the root, because the board's ScrollViewer is deliberately full-bleed so that its scrollbar rides the pane's edge, and because a root margin would also inset the drawer, which draws its own. That cost the cards ten pixels, and the layout suite is what said so: TheHostsGridKeepsTwoColumnsAtTheMinimumWithTheDrawerOpen failed, because Border.tile's 224 was derived from the board's old 16-pixel margins and the grid quietly collapses to one column at exactly the size this application guarantees. 224 becomes 214, with the arithmetic in App.axaml rewritten — it had also gone stale in a way that hid itself, still citing the 1016 minimum and 190 rail from before v5b, whose two changes happened to cancel. ◆ PINS LEAVES THE RAIL, and only the rail. KnownHostsScreen is still built and still one click away, from "Host keys" on the Keys screen's own header, which was always the second way in. The row was kept through v5b on the grounds that the mock has no screen for approved host keys — a reason for the screen to exist, and never a reason for a rail entry once the keychain had a door to the same place. Two rows landing on one screen is a rail that has to be read twice. MainWindowViewModel.IsKnownHostsShowing stays: it names a real shell state and ShellFlowTests still asserts on it. design-import-gaps.md recorded that row as a deliberate deviation and manual-checks.md Phase 1.1 walked the rail entry by entry; both are corrected, and the manual check now reaches the screen the way a user would. The layout suite's rail row count moves from six to five with it. 153 layout tests and 446 shell tests pass. The frame is confirmed by eye; the Hosts inset and the rail are covered by the layout suite but were not seen running, because the instance launched to check them came up locked.
