A connected phone was drawing five rows of chrome around the thing the user opened it for. The vault header at 56, the terminal's own tab strip at 52, a connection line at 36, the shells strip at 46 and the four-entry bottom bar at 64: at 360dp that is about a third of the display, and every row of it was about somewhere the user was not. What replaces them is one 52-pixel bar drawn by the surface itself — back on the left, the session pills, and a `+` across from them — and then the terminal. Three of those rows belong to `PhoneShell` and each is now bound on `IsShowingPages`. That is the same question asked once rather than three conditions that could drift: the surface is either a page or a terminal, and these are the chrome a page has. The header needed a wrapper because Avalonia's bindings have no "and" and it already had a condition of its own; the strip needed one for the same reason. The bottom bar had none and is bound directly. The back arrow goes to the page the terminal was opened over rather than to Hosts by name, because the system back gesture already picks that and an arrow landing somewhere else would be the second of two answers to one question. The bar's `+` raises a sheet offering the three connections this application can make — a shell, a host's files over SFTP, a bucket — since SFTP and S3 used to be two taps through the bottom bar's MORE and the bar is not on screen here. A control that replaced it and led to one of the three would have quietly removed the other two. Two things moved rather than being dropped. The text-size buttons are pinned at the right-hand end of the accessory key row, outside its scroller: the connection line existed to keep them from scrolling out of reach, and being outside the scroller answers that argument rather than abandoning it. The dialled address moved onto the connecting card, which is the moment it is worth reading — what is being connected to, before anything has answered — and after that the shell's own prompt says it more accurately than a header derived from the keychain ever did. The sheet collapses the renderer rather than covering it. Whether Android's `WebView` composites above Avalonia content the way Win32's child window does is still unverified — `docs/android-port.md` has said so since the port — so this follows the desktop's palette and gives up the rectangle outright, which is correct under either answer. It collapses `IsTerminalShowing` and not `IsTerminalSurface`, because the bar the sheet was raised from is part of that surface and dropping it would take the bar, the tabs and the whole arrangement with it, leaving the sheet floating over the page underneath. `OnSurfaceChanged` is the one place the flag is lowered, and that is the load- bearing half. Every way out of a terminal ends there — a destination, the files screen, the palette connecting to a host, closing the last tab, a lock — and each of them would otherwise leave a sheet set over a page. Not merely untidy: the flag holds the renderer blank, so the next return to the terminal would draw the menu again over a rectangle kept blank by it. Opening is refused off the terminal surface for the same reason from the other direction. The back gesture gains a guard above the switch, in the shape of the editor guard that arrived with the phone's `+`. It is nearer than any of them: with no header and no bottom bar, while the menu is up that gesture is the only way off it other than the scrim and CANCEL. The bottom bar's Terminal entry lost its `IsCurrent` binding. The bar is collapsed on that surface, so the binding could only ever be read as false, and a rule about a state the control cannot be in is a claim that it can. Three tests in `ShellFlowTests`, which is where shared state-machine behaviour for this head goes: the collapse and its recovery, the refusal to open over a page, and the sheet lowering both by a menu entry and by a route it was never wired to. Everything visual needs a device, so it is phase 11 of `docs/manual-checks.md` — and 11.2 is the check that would finally settle the compositing question this head has carried as unverified since the port.
