The trust prompt was two banners at the top of the desktop's hosts screen, so the shell navigated there before letting a handshake raise one: Screen = Hosts, Surface = Page, in OnVaultConnectionFailed and again in the palette's own connect. The reason was sound — a connection can be started from Ctrl+K on any screen, and a question behind whatever somebody is looking at is a question nobody can answer — and it was answered the wrong way round. Rather than making the decision reachable from where the user is, it moved the user to where the decision was, and charged every screen for it. It is worst for the one connection that has no host at all. A machine typed into the phone's connect box is deliberately in no keychain, so a first contact from there judged it on a list it does not appear on, after taking the box that dialled it away. So both heads now draw the decision over the surface. HostKeyCard is the desktop's, and is the counterpart of the phone's HostKeySheet: a scrim with no press handler, because a question with two named answers must not be answerable by missing; the unknown key offering TRUST AND CONNECT, because judging a fingerprint against what an operator published is a decision a person is entitled to make and the only moment they can make it; and the changed key offering no way forward at all, because a button beside that warning is "continue anyway" with two clicks instead of one. The phone needed no new markup — its sheet was already a shell-level overlay, so deleting the navigation is what puts it over the Connections screen. IsHostKeyDecisionShowing is on the shell rather than on a screen because the answer decides an occlusion. A second connection can be refused while a first one is open, so this card is routinely raised over a live terminal, and that rectangle is a native child window: layered over it the card would be sliced at its left edge with TRUST AND CONNECT taking no clicks, which for the most safety-critical question in the product is the worst place for that class of bug to land. IsTerminalShowing gives the rectangle up instead. The banners are gone rather than copied. One prompt in two markups is two copies of the most safety-critical wording here, and the second is the one that goes stale. TWO DEFECTS FOUND BEHIND IT. VaultViewModel.RejectHostKey cleared only the pending key and never the mismatch, so the changed-key refusal had no working exit. That was invisible for as long as it was a banner nothing was drawn over — nothing was trapped, and the next attempt cleared it — and it was already live on the phone, where that refusal is an opaque full-screen panel whose one button runs this command: pressing it left the panel up over every screen the user went to next, including the host editor the panel tells them to open. TransfersViewModel.RejectHostKey has always cleared both; the vault's was the outlier. Its button said BACK TO HOSTS, which was wrong twice over, and now says BACK. And an assertion written for this change could not fail: the palette test asserted the renderer was collapsed in a scenario whose only tab had just been removed, so it was collapsed for want of a session whatever the occlusion rule said. It is gone, with a note pointing at the test that can fail on it. VERIFIED. 1580 tests, build clean, no new warnings, format clean. Three mutations each seen to fail and then seen green again: dropping !IsHostKeyDecisionShowing from IsTerminalShowing, caught by AChangedHostKey_CollapsesTheTerminalItIsRefusedOver; reverting RejectHostKey to clear one flag, caught by RefusingAHostKeyDecision_TakesItOffTheScreen(false) and by that same test; and dropping the two host-key arms from OnVaultPropertyChanged, caught by TheHostKeyDecision_IsAnnouncedToTheWindowWhenItArrivesAndWhenItGoes. That last one is the first test in this repository to watch PropertyChanged, and it is worth being the first: every other assertion about the flag reads it directly, and a direct read passes with the subscription deleted — while the card would never go away. The two layout tests moved with the prompts, from the hosts screen to the card. manual-checks gains 7.4a for the occlusion, 7.4b for getting out of a refusal and 11.7a for the hand-typed case, none of which a test can see; 1.5 and 7.4 are corrected rather than left describing a window that no longer moves. ONE ROUGH EDGE, DELIBERATELY LEFT. On the desktop, refusing a first contact whose tab was the only one leaves the terminal surface with no tabs — a blank rectangle under the strip's "no terminals open · press + or Ctrl+K", which is the one sentence near that rectangle Avalonia can draw. The alternative was falling back to the page, and on the phone that means the host list, which is the bug this commit is about. A desktop connect page would close it properly.
