ci / api image (push) Successful in 24s
Taking pinch-zoom off the phone left nothing in its place, and there was nothing on the desktop
either. This is the replacement, and it is deliberately not the thing that was removed: zoom scales
what has already been drawn, so the remote goes on wrapping to a width that is no longer on screen.
Changing the font size refits the grid and reports the new column count, so the far end is told it
has fewer columns. That round trip is the feature.

The size is one number, owned by the shell. It has to be, for two reasons that pull the same way: it
must survive a relaunch, and it must be reachable from a phone that has no Ctrl key to press. So the
page asks and the host decides — a signed step over a new client opcode, answered with a size over a
new server opcode. The phone's buttons and the desktop's chords arrive at the same place, and a size
set by either is the size both remember.

Stored in settings.json beside the cache rather than in it, and that is not laziness about a
migration. The cache is encrypted and unreadable until a vault is unlocked, and the first terminal of
a locked launch needs the size already. Nothing secret may go in that file; ClientSettings says so
out loud, because the next person to add a preference is the one who needs to read it.

Where it is reachable from differs per head, and only here. The phone gets A− and A+ on the
connection line — not in the accessory row, which scrolls, and a control that fixes unreadable text
must never be the thing that is off-screen. The desktop gets the three chords every terminal
emulator has, answered by the page while a terminal has focus and by the window when it does not,
plus a row in preferences that shows the current value and names the chords rather than replacing
them. Someone whose terminal is too small to read is not in a position to go looking.

Clamped 8 to 32. Below eight a monospace grid stops being legible and becomes a texture, and every
column of it is still a column the remote is being told exists; above thirty-two a phone in portrait
has too few columns to hold a prompt. The buttons disable at the ends rather than accepting presses
that do nothing, which on a terminal reads as the application having stopped responding.

The preferences screen's header comment claimed none of the design's terminal settings could be
saved, and listed the three things that were missing to make one work. All three now exist, so it
says which one is real and why the other five still are not.

Verified with the protocol suite — including that the step byte round-trips signed, since read
unsigned a step down arrives as 255 and clamps to the largest font, making "smaller" do the most
dramatic available version of "larger" — a data-plane test that the chord is heard with no session
registered, and five shell tests: the default matches the renderer's, both clamps hold, reset works,
and a size chosen in one shell is there in a second one over the same profile directory. Layout
suite and both heads build.

jaap-janandClaude Opus 5 73c7e2a1e3 Point a release build at the hosted server, and a debug build at the clone
The shipped default was http://localhost:5233, which is the address the API serves under
dotnet run and a machine an installed application is not running. Somebody who installs a
release and accepts the field unread is signing in to nothing.

Two defaults now, because the two audiences never overlap. A release build offers
https://ssh.dodotech.cloud, so a first launch needs no address typed at all. A debug build
keeps the loopback address, and that half matters as much: shipping the hosted address into
a clone would point every development launch at production, and sign-in is the call that
provisions an account there.

The remark carries the reason the schemes differ, since the pair now looks like an
oversight rather than the deliberate thing it is — the API's first launch profile is
plaintext on 5233, and an HTTPS client meeting a plaintext port reports a TLS failure that
reads like a certificate problem.

The test spells out both branches rather than asserting the constant, which would pass
however it were edited. What it is really guarding is that a release never ships a
developer's loopback address and a debug build never points a clone at production, and it
can only guard those by naming them.

Verified by running the shell suite in Debug and in Release.

jaap-janandClaude Opus 5 39b7e5620f Say which half of signing in is happening, and which half failed
A sign-in against a production Keycloak was reported as the shell hanging on "Opening your
browser to sign in…" and then, some time later, saying "The server returned 500". Both
halves of that are the message's fault. The browser flow had already succeeded — the
provider authenticated the user, the code came back, the tokens were exchanged — and what
was actually happening was a round trip to the DodoSSH server for the account. The screen
went on describing a browser nobody was waiting for.

The status now moves when the browser half ends, so the wait that follows is attributed to
the server being asked rather than to the browser that has already answered.

The failure gets the same treatment. "The server returned 500" is the API client's phrase
for any server it talks to, and read underneath a sign-in button it is naturally taken as
the sign-in having failed — which sends somebody to their identity provider's logs to find
out why a thing that worked did not work. It now says signing in succeeded, names the host
that failed afterwards, and says the reason is in that server's logs, because this side
cannot know more than that.

Nothing here fixes the 500. It changes which of the two servers the next person goes and
looks at, which was the actual cost of the old message.

Verified against the shell suite, including the case that asserts a failed command leaves
the window enabled.

jaap-jan 4300d917a8 Stop making people wait for a handshake, and give the host list a pointer
ci / build and test (push) Failing after 3s
ci / android head (push) Failing after 2s
Connecting held the vault's busy gate, which meant a window that did nothing visible for
as long as a machine took to answer — and against one that is merely asleep, that is the
whole timeout. The gate is gone from that one command. A tab now appears in the strip in
the same turn as the click, carrying "connecting…" rather than a pane, and the terminal's
rectangle draws a card naming the host and the address being dialled. Every other screen
stays usable, and two connections can be in flight at once.

That splits the vault's one connection event into three, carrying an attempt id, because
"which tab is this about" can no longer be answered by "the most recent one". The id also
buys the two kinds of not-connecting their different endings: a refusal stays in the strip
as a tab holding its reason, since by then the user is quite likely three screens away and
a status line they are not looking at is not where a failure should end; a host key
question takes the tab away and puts the window back on HOSTS, because the prompt is drawn
there and a tab claiming failure would be competing with the thing about to resume it.

ConnectAsync takes no CancellationToken any more, and that is load-bearing rather than
tidying. A [RelayCommand] over a method that takes one generates a command that cancels
the previous execution's token on every invocation — so asking for a second machine
silently abandoned the first, measured as the first tab disappearing with "Cancelled." the
instant the second was asked for. Giving up on a connection is closing its tab, and a
session that lands after that is adopted rather than dropped: a shell running with nothing
naming it cannot be closed at all.

A tab is marked active on IsShowing rather than IsSelected. The selection survives
navigating away — that is what makes the strip a way back to a terminal instead of a way
to lose one — so a tab lit while preferences filled the window was a second "you are here"
mark pointing at something nobody could see. The nav rail's own entries have always made
this distinction.

The host list grows the two gestures it looked like it already had. A right click selects
the row under the pointer before opening a menu of Connect, Edit and Delete — the menu is
on the list rather than in the item template, so its entries are the vault's own commands
and not a row's, and it is cancelled outright over a group heading. Dragging a host onto a
heading files it there, onto a host files it beside that one, and onto UNGROUPED takes it
out of a group; the write is one field of one host through the same repository a save
uses, refused while the editor is open because a drop is a gesture on the list and not on
a half-typed form.

Clicking a result in the palette connects, which is what a list of hosts under a search
box looks like it does. It went through the shell's own command, so the pointer and Enter
take one path.

And the files screen's two pickers followed the vault's lists once, at unlock: a host or a
bucket created afterwards could not be picked until the keychain had been locked and
opened again, with nothing on screen explaining why the machine plainly in the host list
was missing. They follow the collections now, re-finding the selection by id across the
rebuild a sync pass causes every minute.

165 shell tests and 69 layout tests green, including the connecting tab, both failure
endings, two connections at once, a connection in flight across a lock, and the right
click acting on the row under the pointer rather than on the selection. The drag itself is
in docs/manual-checks.md with the rest of phase 7 — headless Avalonia has no platform
drag, and a test that claimed to have dropped something would pass while confirming
nothing.

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.

jaap-jan 2caedd93ff Merge branch 'main' into the Android head
Main grew the screens the host-management plan called for — hosts, pins, snippets, logs,
import, teams — plus the ObjectStore and Import projects behind two of them, and moved
WindowsDeviceKeyStore into the desktop head's Platform folder.

Five of those view models landed in a directory this branch had already moved, so they
join the rest in DodoSSH.Client.Shell: git spotted the rename and put them there, and the
namespaces followed. Shell picks up ObjectStore and Import as a result, which the Android
head then gets transitively and will use neither of at first — scoped storage means there
is no ~/.ssh/config to import, and file transfer is out of its first scope.

Desktop suites green at 155 and 64.

jaap-jan fe9d7fc289 Give DodoSSH a phone, and a shared shell for both heads to drive
The Android head from docs/android-port.md, taken as far as its step 6.

Step 3, the spike, is answered and its throwaway screen is gone: libsodium.so and
libe_sqlite3.so are both in the arm64 APK, so NSec resolves its native half on Android
despite shipping no Android build, and the local cache opens. Two findings the audit
could not have had: Avalonia.Controls.WebView only ships net10.0-android36.0, which
settles the open "which Android versions" question at targetSdk 36; and Android has
blocked cleartext HTTP since API 28, so the terminal renderer needs a network security
config scoped to 127.0.0.1 or the WebView loads nothing.

DodoSSH.Client.Shell is new and is why the phone can exist: the view models, the terminal
renderer files and the palette moved there so both heads drive one state machine and draw
from one set of tokens. The desktop head is otherwise untouched and its 144 tests still
pass.

The platform pieces behind interfaces that already existed: the profile directory from
filesDir, a device key wrapped by a StrongBox-backed key that a fingerprint releases, and
a foreground service so a shell outliving a vault lock stays true on a platform that
stops backgrounded processes.

Sign-in is deliberately absent rather than approximated. It needs an app link, because
reusing the desktop loopback listener is the attack RFC 8252 section 8.3 names.
