jaap-jan aff776cb42 Rebuild the terminal's keypad, and fix what a device run showed
ci / build and test (push) Failing after 3m0s
ci / desktop nightly (push) Skipped
ci / api image (push) Skipped
ci / android head (push) Successful in 3m56s
Six defects, all found by running this head on an emulator against a local API rather than by reading it.
They are in one commit because two of the files carry several of them and splitting those would mean
hand-editing patches; each is argued at its own site.

── the keypad, which is most of this ───────────────────────────────────────────────────────────────────
It was eleven 30-by-44 keys in a horizontal ScrollViewer, and it was wrong twice over. A pan and a press
begin with the same few pixels of travel, so a thumb coming down at an angle — which is how a thumb comes
down — was read as the start of a pan and the press was never delivered; the row slid slightly instead.
And 30 tall is well under the 48 Android asks for, so the presses that did arrive were hard to aim. The
arrows, the keys pressed most and in sequence, were the ones parked past the right-hand edge.

Termux, Termius, JuiceSSH, ConnectBot and Blink all ship this row and not one of them scrolls it: they
divide the width evenly and add a second row when the set does not fit. That is not convention for its own
sake — a key whose position is fixed can be hit without looking, which is the whole point of a modifier row
used while reading the output above it.

So: two UniformGrid rows, every key an equal share of the width, nothing scrollable, 40 tall. Every key
kept. Arrows on the lower row where the thumb rests, reordered to ← ↓ ↑ → so the pairs that undo each other
are neighbours. It costs about 51 pixels of terminal, four or five lines, and that is the right trade: the
row that was cheaper did not work.

The keys also gain a pressed state, which they had none of. They are Focusable="False" so that using one
does not take the keyboard off the terminal, and a button that never takes focus never shows the adorner
Fluent would otherwise give it — leaving no feedback at all on a control whose only job is to be pressed.
Their looks move from assignments in the code-behind to Button.hotkey, which is what lets a style say
:pressed, and the Ctrl latch becomes a class rather than two brushes written by hand.

── and five smaller ones ────────────────────────────────────────────────────────────────────────────────
The keyboard's inset was never cleared when the app was resumed without the keyboard it was applied for.
Android takes the keyboard away as the activity stops and Avalonia's input pane raises no StateChanged,
the pane going with the window rather than closing in front of one — so the interface came back holding a
whole keyboard's height of empty canvas. 838 of 2340 pixels on a Pixel 5, on every screen, until something
opened and closed the keyboard. MainActivity now raises PhoneEnvironment.Resumed and PhoneShell re-asks the
pane. It asks rather than assuming zero: a permission prompt or the biometric sheet can hand the activity
back with the keyboard genuinely still up, and flattening the inset there would strand the focused box
under a real one.

TextBlock.detail never wrapped, where .body beside it always has. A block that neither wraps nor trims lays
out at its full single-line width and the parent clips it, with no ellipsis to say anything is missing — so
the add sheet read "A machine to connect to, filed under a group if you" and stopped. Which of the fifty-odd
.detail blocks overflows is a function of width and font scale rather than of the string, so this is a style
rather than an attribute on the handful visibly wrong on one phone. The nine that genuinely want one line
now say NoWrap beside their TextTrimming, which is the pairing that was always meant.

The two port boxes are NumericUpDowns and were the only unthemed controls on this head — Fluent's border and
fill, next to a TextBox.field sharing their row. App.axaml has styled NumericUpDown for the desktop all
along; this head never had one.

Three buttons classed "icon accent" were painting Fluent's own Button.accent, #6275AC, a blue in no palette
here. The desktop overrides that style and this head did not, so the same class read correctly there and not
here.

The host key sheet said "First contact with 10.0.2.2 · 2222 . Nothing in this keychain…" — Avalonia puts a
space between adjacent Runs and the last one began with the full stop. A gap before a full stop, on the one
dialogue whose whole job is to be read carefully before it is answered.

── checks ──────────────────────────────────────────────────────────────────────────────────────────────
manual-checks gains 10.4a and 11.10f. 10.4 already covered dismissing the keyboard with back or the
chevron but not leaving the app with it up, which is the path the inset bug shipped through; 10.4a covers
both directions, since a fix that flattened the inset on every resume would pass one half and fail the
other. 11.10f guards the keypad against a ScrollViewer being put back around it.

jaap-jan 7ca74a1e35 Retint the scrims to the v5 canvas, quick connect at the spec's 60%
Five scrim hardcodes still dimmed through the old canvas #0E1220; they
now sit on #05050A. Each keeps its alpha except QuickConnect's backdrop,
which the v5 spec pins at rgba(5,5,10,0.6) — its essay drops from 80% to
60% of Canvas to match.

jaap-jan 4f9faa2fe3 Ask about a host key where the connection was made, not on the host list
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.

jaap-janandClaude Opus 5 5593f337b6 Give the phone the second design, and both heads the palette it arrives with
The Android v2 design is what this head draws now: four destinations in a bottom bar — Hosts,
Terminal, Keychain, More — with snippets, SFTP, S3, logs and preferences one tap deeper behind the
last. The first design's four had nothing behind them, which is what made a hub worth building.

The palette moved from green-black to blue-black, and it moved in the shared project because that is
where it lives and the desktop v2 specifies the same seventeen tokens. One colour changed meaning
rather than value, and it is the only semantic change in the file. Green used to *be* the accent, so
Ellipse.dot.live filled with Accent and "the thing to press" and "a shell is open on this host" were
the same colour by construction. v2 makes the accent blue and keeps a green for status alone, which
finally separates them: Live is that green and nothing merely interactive may use it. The accent is
also two colours now — Accent fills, AccentText writes — because a row of chips in the fill colour is
a row of things that all look like the primary action.

A palette is not one file, which is the part worth knowing before the next one. Nine hex literals
lived outside it: the nav bar's own label colours, the accessory keys and their Ctrl-latched state,
two scrims, the window background Android paints before Avalonia has a frame, and the launcher
vector. The two C# sites now resolve from the dictionary by name rather than restating it. The
renderer's page cannot — it is served to a WebView over a loopback socket — so terminal.css and
terminal.js keep hand-copied values and say so at both sites.

ShellScreen gained More and Buckets, appended rather than slotted in. SFTP and S3 are one screen over
one TransfersViewModel differing only in which picker they offer, and the kind is set by the button
that navigates rather than on arrival — doing it in OnScreenChanged made every arrival at Transfers
force the picker back to hosts, including the desktop's own rail arriving at a screen with a bucket
already open. It refuses to change kind while a session is live, because there is one session behind
both destinations and switching under it would title a screen S3 while it listed an SFTP host.

What the design draws and this does not, on the usual grounds. The FORWARDING screen: nothing here
forwards anything, so every toggle would be a control with no effect — it is a paragraph on the hub
naming the absence, for the reason the desktop keeps TEAMS in its rail. The terminal's `23 ms · fwd
5432`. An ED25519 badge and a SHA256 line on keychain cards, which need an algorithm field and a
fingerprint the item type does not have. An `agent` chip, for an agent that does not exist. Snippet
run history and exit codes. The Logs FOLLOW pill, which claims a live tail over records that are
written once at close and read when the screen opens, and the severity filter, which has nothing to
count — that chip row is spent on the real choice, which of the two logs. S3 bucket totals and
lifecycle. And the + on HOSTS, which would open a host editor this head has not got.

SFTP is browse, open and delete. Both transfer commands work, and what they work against is the local
pane: QueueDownloads writes to Path.Combine(LocalPath, name), and LocalPath starts at
SpecialFolder.UserProfile, which on Android is the application's own private directory. A download
would have reported success and left the file where the person who asked for it cannot open it, which
is worse than not offering it — a refusal is visible and a file in /data/user/0/ is not. The queue is
not drawn either, since nothing here can put anything in it. Both return with the document picker.
The foreground service still counts zero transfers, and the reason moved rather than went away.

Four defects worth naming, because three of them are the kind that compile. A Button as a ListBox
ItemTemplate swallows the pointer press before the list sees it, so the files listing selected
nothing and every command reading the selection did nothing — the row is a Border now and the
phone-only single-tap-to-open is a Tapped handler, which also keeps a desktop single click from
walking into directories. Avalonia type selectors are exact, so TextBlock.fingerprint never matched
SelectableTextBlock and every fingerprint on this head rendered proportional and unwrapped: that was
breaking the never-truncated rule on the host-key sheet already. The new two-level hierarchy had no
handler for the system back gesture, so back left the application from a log screen. And the tab's
close cross had shrunk to a 30x32 target flush against the select target, which is the one control
here that ends a shell with no confirmation and no undo.

Fingerprint unlock is raised on arriving at the lock screen rather than waiting for its button, which
is still there. Only at launch: a lock the user asked for is not answered with an immediate request
to unlock, which makes LOCK look inert and trains the reflex of authenticating at a prompt nobody
asked for. And once, because a declined gesture leaves the passphrase box exactly where it was and a
prompt that came back after being dismissed would be a modal you cannot get out of to type into it.

Two fixes fall on the desktop. Its file listing coloured directories with Info and executables with
Accent, which was blue against green and is now two steps of one blue; an executable is Live now.
And a bucket's folders were drawn with a 0001-01-01 timestamp, because a prefix has no modification
time — blank now, for the reason a directory's size is blank.

Verified by the whole suite: 1309 tests over nineteen projects, none failing, including the layout
suite that stands up real Avalonia and parses every desktop screen. Both heads build. Not verified on
a device — nothing in this head ever has been; see docs/android-port.md.

jaap-jan 7a3a521c59 Give the phone the rest of its screens, and a way in
ci / build and test (push) Failing after 2s
ci / android head (push) Failing after 1s
All seven screens of the design, plus the two it does not draw because it starts at an
enrolled phone: naming a server, and choosing a passphrase.

The five states docs/android-port.md worried about losing at 360dp are all here and none
of them softened. The changed-key refusal is a full-screen panel rather than a bottom
sheet, because a sheet is swipe-to-dismiss by convention and that screen must have no way
forward. The recovery code raises FLAG_SECURE for its own state and lowers it afterwards,
so the sentence about screenshots is true rather than decorative. The delete
confirmations keep their counts and replace the row in place.

Signing in works, and the seam it needed is worth more than the implementation:
IAuthorizationCallback now sits between OidcClient and the loopback listener, so the two
heads differ in where the response arrives and in nothing else. PKCE, the state check,
discovery, the token exchange and the key binding stay one implementation — a second OIDC
client would be a second place for a security bug to live. The phone registers a
private-use scheme with the system rather than binding a loopback port, which on a shared
device any other app can do first.

The accessory key row needed TerminalWorkspace.SendInputAsync: ordinary typing goes from
the renderer straight down the socket, and there was no way in for the keys a software
keyboard does not have. Ctrl latches, because one thumb cannot chord, and the latch is
drawn — a modifier that is on and does not look on is how somebody sends ^L to a database
prompt believing they typed an l.

597 client tests green, including two new ones for the input path and one for the
terminal surface command. Nothing has run on a device.
