jaap-jan d07b336868 Free the terminal from the Hosts screen, and fill the room it left
The WebView sat inside the Hosts grid, so navigating to Files or the keychain
hid every open terminal and the strip that named them. A connection you had
opened was invisible from four of the five screens. The window now has two
surfaces rather than one: a nav rail that says which page you are on, and a
terminal strip that is always there and switches the whole content area to a
shell. Screen keeps meaning "which page" and never becomes a sixth kind of
page, which is why this is two properties instead of one enum with a terminal
member in it.

Every screen lives inside one wrapper panel that collapses when a terminal is
showing. That is not tidiness — the WebView hosts a Win32 child window that
composites above everything Avalonia draws, so a screen left visible over its
rectangle is a screen sliced in half, and this window has shipped that defect
once already. One decision point, IsTerminalShowing, and a nested panel rather
than five compound bindings nobody would remember to extend.

The focus choreography is the part no test in this repo can see. Every reveal
path now focuses in the same turn the WebView appeared, so all three of them
post at DispatcherPriority.Loaded and let the native control re-push its bounds
first. Going the other way had a real bug: the screen-changed branch called a
bare Focus() where it had to release the keyboard from the native child, so
switching from a terminal to Files silently ate the first keystrokes. Rare
before this commit and the primary gesture after it.

The tab strip grew a cross inside each tab, a plus that opens the quick-connect
palette, and middle-click close. Nested buttons are correct here: Avalonia
handles a left press on the cross and deliberately does not handle other
buttons, which is exactly what lets middle-click bubble up from the cross as
well as the tab. The test is PointerUpdateKind rather than
IsMiddleButtonPressed, because the latter reports button state and is also true
for a left press made while the middle button happens to be held. The handler
is on the tab and not the strip, so the background closes nothing by
construction. Plus opens the palette rather than a flyout, since a menu
dropping into the WebView's rectangle may or may not composite above a child
HWND and this repo does not make rendering claims it has not photographed.

Everything a user reads now says keychain. The wire, the database and the
cryptographic spec still say vault, deliberately: renaming those is a migration
and a protocol change for a word. That split is written down rather than left
to be rediscovered as an inconsistency.

Four things that were squeezed into the keychain's category rail, or into
nothing at all, now have screens. Pinned host keys get one, with fingerprints
never truncated and a filter that matches them, because comparing what you have
against what the operator published is the whole workflow; the approved date is
read out of the item's UUIDv7 rather than added as a column, and says so, since
it means first approval and not last use. Keys can be generated in the client,
which needed the openssh-key-v1 container written by hand — there is no BCL or
NSec helper, and the PKCS#8 route is unverified in the SSH library this uses.
The armour carries no passphrase: encrypting it needs bcrypt_pbkdf, which is
Blowfish with a swizzle, in a project whose crypto is otherwise entirely
libsodium, for a protection the key's own remarks argue is redundant inside a
vault. Generation fills the existing editor and stops, so SAVE stays the one
thing that writes. ~/.ssh/config can be imported behind a preview that is
ticked per row and writes nothing until the button; IdentityFile records the
path and imports the key material only on an explicit opt-in, because reading
somebody's private key into a vault is precisely the act this product exists to
make deliberate. Match blocks and ProxyJump are reported rather than obeyed —
one cannot be evaluated statically and the other has nothing behind it to route
with, and a preview that implied otherwise would be worse than one that admits
it.

Files can be dragged in all four directions that are honestly available. Remote
to Explorer does not ship and is not pretended to: the shell wants the bytes
during the drop, which needs a virtual file and a native COM data object,
outside what Avalonia offers. Note for the next person that Avalonia 12
replaced the drag model outright — DataObject and DataFormats are no-op stubs
and IDataObject is not in the reference assembly, so every tutorial written for
11 does not compile here.

Hosts can be grouped, flat and never nested. A parent id merged as a scalar
lets two offline clients each re-parent A under B and B under A, producing a
cycle inside an encrypted payload that no server can police and every reader
would have to detect for ever. Membership lives in that payload rather than in
the one plaintext concession ADR 0001 allows, whose test is that the relay
cannot function without it — nothing on the server reads a group, so what
plaintext would hand over is a clustering of the estate for nothing. The
plaintext column reserved for it is dropped, provably always null, and the
server now refuses a client that sends one; it was never populated, was copied
on apply, and was not cleared on delete, so a group id would have outlived the
host it described.

Snippets insert through xterm rather than through the pump, because xterm is
the only thing that knows whether the remote has bracketed paste on, and that
is what makes a shell treat embedded newlines as text instead of as execute.
The host process moves opaque bytes and never parses output, so it would have
to guess, and guessing wrong runs every line. Running is off by default and the
copy says the text goes into whatever is there — the terminal has no notion of
being at a prompt, and may be in vi or at a password prompt with echo off, so
the Enter the user presses themselves is the entire safety property.

Connections and keychain changes are recorded as synced encrypted items, which
is what makes them auditable by a team later and costs the server knowledge of
connection rate and timing from row counts alone. ADR 0001 already concedes it
cannot hide that class of metadata; the trade is now written into it rather
than left implicit. A connection entry is written once, at close, which is what
makes a synced log tractable: nothing to merge, one outbox row, no chance of
colliding with itself. Live sessions come from memory, not from the log. The
write is void by contract and posts to a bounded channel, because putting an
encrypt-and-write on the teardown path of every session is how closing the
application comes to take four seconds. A ticket opened before a lock still
closes afterwards, since a shell outlives the vault. The activity log hooks the
one generic repository every kind writes through, so it cannot miss a caller —
which is also why the log kinds themselves declare they are not audited, or the
first entry would write an entry about writing an entry. It records the names
of the fields that changed and never their values; a log with an old password
in it would be a plaintext credential store with no vault around it. Retention
is 90 days or 5,000 entries, whichever bites first, pruned on the sync loop
rather than on a second timer.

That log traffic then broke the status line, which is worth recording because
the fix is a shape and not a patch: background sync counted its own log rows as
pushed items, so the quiet rule stopped being quiet and every action's message
was overwritten a second later by a sync report. The report now separates log
rows from user items and the rule reads the latter.

S3 buckets appear as a remote in the file browser, behind the same interface an
SFTP session implements, so the queue and both panes did not have to learn what
they are talking to. Uploads go through a pipe, because the queue wants to
write and the SDK wants to read; memory is then bounded by the part size
instead of buffering a file to disk twice.

Finally, the Windows device key store moved out of the session project, which
was the one thing keeping it from being portable — everything else in it is
platform-neutral, and a Windows CNG dependency in the middle of the vault code
meant a second head could not reference it without dragging Windows along. The
seam that made the move free was already there. docs/android-port.md is the
audit behind that: what ports, what does not, in order of cost, the four
decisions taken, and an inventory of every screen and state the interface has
to carry, written so a design can be made from it directly.

dotnet build, dotnet test and dotnet format --verify-no-changes are all clean:
1240 tests at zero warnings, including the end-to-end suite against real
containers. The manual checks that headless Avalonia cannot make — the drag
from Explorer, a generated key against a real host, twelve tabs at the minimum
window width — are listed in docs/manual-checks.md and are still outstanding.

jaap-jan 0b261c4d39 Stay signed in, come back online by itself, and let a machine be given up
Three things a machine that has been set up could not do. Unlock now takes
Enter, which is the gesture everybody makes after typing a password and which
did nothing until they found the button.

Signing in survives a relaunch. The refresh token is kept in the local cache,
sealed under the vault's own cache key, so a later launch resumes the session
through the refresh grant with no browser and nobody present — and because it
is sealed under that key, only an unlocked vault can resume it. A locked
client therefore cannot reach the server at all, which is a consequence worth
stating rather than working around; docs/crypto.md §3.2 records it. Every sync
pass asks the shell for a connection rather than reading one captured at
unlock, so a laptop that unlocked on a train is online within a minute of
finding a network, with nothing pressed. Unlocking itself still never waits on
a socket.

Signing out empties this machine: the profile, the cached items, the outbox
and this machine's device key, with the account's row withdrawn when the
server can be reached. It asks first and says what it costs — the outbox count
when the vault is open, an admission that it cannot be counted when it is not,
and the shells that keep running either way. The vault is on the server and is
untouched, which is what makes the same button the only honest answer to a
forgotten passphrase, so it is on the unlock screen as well as in preferences.
It cannot end the session at the identity provider, and says so.

Two defects surfaced on the way. The synchronisation pass that runs when the
vault opens never ran at all: the loop is started from inside the unlock
command, so the busy flag it yields to was raised by that command — the first
sync was a minute late on every launch. And signing in from preferences while
unlocked threw an unlock screen over an open vault whose keys were still in
memory.

The unlock card and the new confirmation live in their own controls because
MainWindow cannot be laid out headless, so markup left inside it is markup no
test can measure; both are now measured at the window's minimum size in the
shapes that grow. What is still unverified is the composed window itself.

jaap-jan 9a76eced14 Give hosts and terminals their own screen, and the rest of the vault another
ci / build and test (ubuntu) (pull_request) Canceled after 0s
ci / build (windows) (pull_request) Canceled after 0s
Rebuilds the client's shell from an imported design: a titlebar and nav rail
it draws itself, real multi-session tabs over the one WebView, a Ctrl+K host
search, and a vault screen that merges keys, passwords and pinned host keys
into one table. Hosts left the vault column for their own screen beside the
terminal, which is what the design asks for and turned out to be the better
split anyway.

Two screens the design shows have nothing behind them yet — file transfer
and teams — and say so plainly rather than rendering invented data; every
other gap between the design and this build is recorded in
docs/design-import-gaps.md.

jaap-jan c5dec2d68e Measure the vault column instead of arguing about it
Nothing in this repository loaded a .axaml, so the one class of defect this
window has actually shipped — a control arranged past the edge of its container,
where it cannot be clicked — was the one class nothing could catch. The setup
screens rendered sliced once, with their buttons unreachable. The vault column is
the next candidate: 340 pixels wide, two lists and two editors, and the only
thing keeping it from clipping its own Save button at the window's 520-pixel
minimum is a state rule that one editor may be open at a time.

That rule was added on the strength of an argument. This adds an
Avalonia.Headless project that lays real XAML out at a real size and reports
what a user could not reach, and the argument is now a number: with both editors
open the column overflows, so the rule is load-bearing rather than defensive.
BothEditorsAtOnce_DoNotFit_WhichIsWhyTheRuleExists is the test, and it says what
to do if it ever starts passing — the column has room, so delete the rule, not
the test.

Two findings arrived by measuring rather than by reasoning, and the first one
changed the design.

MainWindow cannot be shown headlessly at all. Showing it attaches the terminal's
NativeWebView, whose Win32 adapter initialises WebView2 on attach, and WebView2
refuses a non-STA thread — which is exactly why Program.Main carries [STAThread]
and is written down in that comment. A HeadlessUnitTestSession owns its
dispatcher thread and offers no apartment choice, so the whole window is out of
reach at any size. That is pinned as a test asserting RPC_E_CHANGED_MODE by
HResult rather than by message, so a future Avalonia that makes the adapter lazy
will fail it and the harness can be widened.

So the column had to become its own control to be measurable, which is the
extraction the type-selector rework wanted anyway. Keyboard release moved with
it: MainWindow used to call Focus() on HostList by name, and now asks
VaultColumn.KeyboardTarget. The window decides that the keyboard should leave the
terminal and the column decides where it lands — which is the seam the rework
needs, because once the column shows one list at a time, "which list owns the
keyboard" is a question only the column can answer.

The second finding is the way this kind of test lies quietly. The hint class
lived in MainWindow.Styles and carries TextWrapping. A Window's styles reach its
whole tree, so nothing about the application depended on where it lived — but a
control laid out on its own loses them, and every hint paragraph would have
measured as a single line. The harness would have passed while measuring heights
that were all too small. The three shared classes now live in App.axaml, which
changes no rendering and makes the measurement honest.

The detector is calibrated in both directions, because a clipping detector that
never fires reads as a guarantee: a deliberately clipped Save button is caught by
name, and a list longer than its viewport is exempt. Scrolling is how a list is
supposed to handle more rows than fit, and without that exemption the host list
would fail the moment it had content. It also mis-fired once and the rule is
narrower for it — an empty ListBox is zero pixels tall and correct, so "arranged
with no size" now applies only to controls the theme gives a height to.

Skia rather than the headless drawing stub, deliberately. The stub's font manager
invents glyph metrics, and text height is an input to every stacked panel in this
column, so measuring against it would produce numbers that are self-consistent
and unrelated to the application.

A separate test project rather than more tests in DodoSSH.Client.App.Tests.
Avalonia's application, dispatcher and platform are process-global singletons
initialised once, and that project's identity is the shell's state machine
without Avalonia — the whole reason sign-in is a delegate. The fakes needed to
reach a real unlocked vault are shared from DodoSSH.Client.Session.Tests by
source link: a project reference would make one test project a library of
another, and a copy would be a third implementation of the same decision table
drifting from the other two.

855 tests green, 10 of them new. Zero warnings, dotnet format clean.

Not done, and this is groundwork rather than the item itself: the type selector.
The column still holds both lists at once, so a third item type would still
recreate the defect the one-editor rule works around. What is different is that
the rework can now be checked instead of eyeballed — including the claim it is
being made for, that one editor at a time stops being a runtime rule and becomes
a fact about what is in the visual tree.

What this harness will never catch is the terminal's native child window
compositing over Avalonia content. That is a Win32 property of a real window, no
headless surface reproduces it, and it is the reason the WebView is collapsed
rather than covered.
