jaap-janandClaude Opus 5 c270f3fe39 Import a Hetzner Cloud project's servers, and forget the token that read it
ci / build and test (push) Successful in 3m18s
ci / android head (push) Successful in 3m54s
ci / api image (push) Successful in 30s
ci / desktop nightly (push) Successful in 2m10s
An estate on Hetzner is already described somewhere: the project lists every
server, its addresses, its plan and where it runs. Getting that into a keychain
meant copying forty addresses out of a browser by hand, which is the same work
the ssh_config importer exists to remove for the machines described in a file.

◆ A WIZARD RATHER THAN A SCREEN, AND THE DIFFERENCE IS WHAT EACH STEP COSTS.

ImportScreen reads a file that is already on this machine, so it scans on open
and shows a list. This cannot: it needs a credential that has to be made in
another company's console first, and then it makes a request over the internet.
Those are two moments rather than one, and a screen that mixed the token box in
with the list would ask for the credential again every time somebody came back
to look at the list.

So three steps — token, choose, done — and the first two write nothing. Step two
carries one address choice, one login user and one port for the whole import,
because an estate is reached the same way throughout and a per-server dropdown
would be forty answers to one question.

◆ THE TOKEN IS USED ONCE AND CLEARED, INCLUDING WHEN IT WORKED.

The half worth stating is the success path. Clearing only on failure would leave
a credential capable of listing somebody's whole estate sitting in a text box for
as long as they spend reading forty rows, which is the longest anybody stands on
this screen. Nothing writes it to the vault, to settings or to a log, and
reopening the wizard restarts at step one rather than resuming — a resumed step
two would be a list nothing on screen has the means to refresh, going on looking
current for as long as the application stays open.

Read is the only permission it needs and the note above the box says so: a
Read & Write token would work identically here and would be a credential capable
of deleting the estate, pasted in for no gain. The note also says a token belongs
to one project — there is no API call that will say which, and none that lists
the others — so an account with four projects runs this four times. Without that
sentence the wizard looks like it lost most of the estate.

◆ THE ADDRESS IS A CHOICE, AND TWO OF THE THREE FALL BACK WHERE THE THIRD MUST NOT.

Public IPv4 and public IPv6 fall back to each other: the same machine over the
same internet, so the worst case is a route nobody picked, and the row says which.
Private does not fall back at all. A server on no private network is simply not
importable under that choice — its tickbox is disabled, and neither direction of
the header's tick-all can reach it — because falling back would put an address on
the open internet into a bookmark that was asked to stay off it.

IPv6 needs saying twice over. Hetzner routes a whole /64 and the API reports the
network, which nothing can dial; the address a stock image answers on is the
first one in it. That is a convention of Hetzner's own images rather than a fact
the API stated, so every use of it carries a warning on the row and in the stored
note, and it is computed by setting the low byte rather than by string surgery on
the prefix. It is not an edge case either — IPv4 is billed separately now and a
project built since then can be entirely IPv6-only.

◆ NOTHING IMPORTED HERE AUTHENTICATES, AND THAT IS SAID BEFORE THE BUTTON.

Hetzner has never held the private half of an SSH key. The API will name a
project's keys and hand over their public halves; there is no private half to
bring. So every host arrives bound to nothing and asks for a password until
somebody points it at a key already in the keychain — the same shape an
ssh_config import has with its key tick off, and stated above the button on the
same reasoning: somebody who is not told will conclude the import was broken.

What the note keeps is what does not go stale — the id, the plan, the location,
the image, the labels. The power state is a column and never a note: "running"
about a machine somebody switched off last March is worse than no note.

◆ WHERE IT LIVES: TWO FLAGS OVER ONE CONTENT COLUMN.

Drawn over the Preferences page inside settings mode exactly as ImportScreen is,
with SettingsNav unmoved and the titlebar offering "Back to preferences".
IsHetznerImportOpen is a second flag rather than a "which importer" enum, because
they are two independent facts about the content column and a single value would
need a "neither" member IsImportOpen already expresses; what keeps them from both
being true is that every path that opens one closes the other. The titlebar and
the Preferences page ask IsImporterOpen, which is written against both.

Preferences grows a second importer row beside the first rather than one row that
asks "from where?", which would put a question in front of the far more common
answer.

◆ WHAT IS NOT HERE.

Hetzner's Robot — dedicated servers and Storage Boxes — is a different API behind
a different credential, and nothing in this touches it. Said on the Preferences
row and on the token step rather than left to be discovered by an account that
has both.

And there is no phone layout. This one would work on Android, unlike the
ssh_config importer beside it: it is a token and a network request, the view
model is shared already, and scoped storage has nothing to do with it. What is
missing is a screen — the desktop draws a five-column table, and the phone
version of that is a different layout rather than the same one narrower. Recorded
in android-port.md and on the phone's own Preferences screen, because the note
there previously read as though no import of any kind could work.

◆ TESTS, AND WHAT IS LEFT FOR A PERSON.

HetznerCloudClientTests is 16 cases over the shapes the API actually returns,
against a stubbed HttpMessageHandler: paging followed, the token in a header and
never a query string, a refused token distinguished from a fault at Hetzner's
end, a token with a line break refused before anything is sent, the /64, the
private-network asymmetry, and a server the API described without a name.

ShellFlowTests.Hetzner.cs is 11 more against this fixture's real vault, real
cache and real server — split into a file of its own, as FakeVaultServer keeps
its team endpoints. What they establish beyond the reader's own suite is the half
it cannot reach: that reading stores nothing, that importing goes through the
ordinary create-and-push path and lands on the server with nothing pressing Sync,
that a server the keychain already has arrives unticked, and that the token does
not outlive the request.

Two layout cases measure both steps against the same content budget every other
settings page gets, which is also what proves the markup binds to names that
exist.

Manual checks 2.11a–2.11d are what no test in this repository can do, because
there is no account, no token and no network in the ordinary suite: a real
project listed against the real console, a wrong token, the private choice, and
what an imported host does when you connect to it.

laurensandClaude Opus 5 56c19b006d Stop the updater offering the build it saw first, whatever has been published since
ci / build and test (push) Successful in 3m28s
ci / desktop nightly (push) Successful in 1m22s
ci / api image (push) Successful in 21s
ci / android head (push) Successful in 3m41s
A client two versions behind was offered the older of the two, installed it,
restarted, and was told at once that another update was waiting. Two downloads,
two installs and two restarts to move one step.

The feed was not the problem and could not have been. The nightly release is
deleted and remade on every push to main, so it holds exactly one build: a client
can only ever be offered the newest thing there is. The wrong version came from
this application's own state.

◆ THE PASS STOPPED ASKING, WHICH IS NOT WHAT IT WAS MEANT TO STOP DOING.

    if (!IsAutomatic || State is UpdateState.Downloading or UpdateState.Ready)

Ready means something is downloaded and waiting. The intent behind excluding it is
right — there is no point fetching what has already been fetched — and what it
actually did was skip the check. So from the first thing any process downloaded,
its banner was pinned to that build for the rest of its life, however many newer
ones were published afterwards. On a rolling channel that is the normal case
rather than a corner.

Not re-fetching is still the rule and now lives in FetchAsync, which compares
versions rather than refusing to look: the same build is left alone, a newer one
replaces what was pending. Which is also why FetchAsync answers with what is
*pending* rather than with what the check returned — a client on 1.0 holding 1.1
is told 1.1 by every later check, because 1.1 is still the newest thing on the
feed, so "the check found something" and "there is something new" are different
questions and only the second one is worth a download.

A build already fetched is never discarded, including when a check answers null.
Null means the feed's newest is no newer than the build that is *running*, which
says nothing about the one on disk — that one is still newer, and withdrawing an
offer somebody has already been shown would be the worse answer.

◆ AND A LAST LOOK BEFORE THE PROCESS IS REPLACED, WHICH IS THE HALF THE TIMER
  CANNOT REACH.

The loop asks every six hours. The build that caused this was published minutes
before RESTART NOW was pressed, so no interval anybody would accept would have
caught it. The press now asks once more.

It costs one small request in the ordinary case, because the feed answers with the
build already on disk and nothing is fetched. It costs a download only when there
genuinely is something newer, which is the case where the alternative was two
downloads anyway.

Bounded at ten seconds, and the wait rather than the request: VelopackUpdateChannel
records that Velopack's check takes no token, so cancelling would be observed only
after the call had already returned. Ten seconds bounds a small JSON document
against a network that drops packets rather than refusing them; a refused
connection fails in milliseconds and never reaches it.

Nothing here refuses a restart. An unreachable forge, a look that ran out of time,
a fetch of the newer build that failed halfway — all leave the build on disk
untouched and still newer than the one running, so the restart goes ahead with it.
Hence swallowed rather than reported: Failed is for something a person is waiting
on an answer to, and this person is waiting on a restart they are about to get.

IsRestarting keeps the banner up through it. Everything the strip draws keys off
IsReady and the look moves the state off that, so without it pressing RESTART NOW
made the banner vanish with nothing on screen saying why, for as long as a 120 MB
package takes. It says what it is doing instead, percentage and all.

◆ THE CHANNEL HAD TO LEARN WHICH BUILD IT FETCHED, AS AGAINST WHICH IT LAST FOUND.

Required by both halves above rather than tidied along with them. Matched()
resolved an AvailableUpdate only against `found`, which a check overwrites — and
both changes make this application check while a build is already downloaded. A
check that lands a newer answer and then fails to fetch it, or is given up on
halfway, leaves the shell restarting with the build it already has and Matched()
throwing at it: the offer real, the package on disk real, and the only thing wrong
being that the channel had forgotten which one it was. A slow forge became a
refused restart.

So `fetched` is recorded after a download returns, tried before `found`, and
survives every later check.

Settings → General claimed checks start "a couple of minutes after launch", which
has been untrue since the first pass moved to launch. It now also says the loop
keeps asking while an update is waiting, because that is the behaviour somebody
reading that row would want to know about.

UpdateFlowTests goes from 21 to 28: the pass asks again and fetches once, the
pending build is replaced when the feed moves on, a superseded offer reappears
through a dismissal, the press installs what the last look finds, and the three
ways the last look can fail all still install what was already on disk. Check
16.7a is the manual half, needing two real releases.

laurensandClaude Opus 5 06369274dc Let the session address be selected, and copied whole
ci / build and test (pull_request) Successful in 2m49s
ci / android head (pull_request) Successful in 3m10s
ci / desktop nightly (pull_request) Skipped
ci / api image (pull_request) Successful in 5s
The address at the head of the session column is the one place the desktop
head prints the endpoint it actually dialled, and it was a TextBlock — which
in Avalonia is a drawing of a string rather than a string. The next thing
people do with an endpoint is paste it somewhere: into a second client, into
a ticket, into the ssh command being written in the window beside this one.
Retyping is how a digit goes missing from an address that is mostly digits.

SelectableTextBlock, which is what the rest of this application already
reaches for wherever a string is on screen to be taken away — a fingerprint,
a public key, a recovery code, a snippet's command. Nothing else about the
row moves: same font, weight, colour and trimming, same tooltip, same close
button beside it. The sidebar is one control drawn on both surfaces, so SFTP
gets it for the same reason it gets everything else in that block.

The trimming and the selection do disagree at the long end, and the fix for
that is not to drop the trimming: the ellipsis is there because a long
account@host:port would otherwise push the close button off the edge of a
panel whose whole point is that it can be got rid of. A drag reaches only the
glyphs that were drawn, so a trimmed address has to be taken with select-all
— and select-all takes the whole thing, because the ellipsis is a drawing and
not a shorter value. That is the half a test can quietly lose, so it is the
half the new test asserts, on the longest address the suite has rather than
on one that fits and would pass either way.

ci / android head (push) Successful in 3m33s
ci / desktop nightly (push) Successful in 1m26s
ci / api image (push) Successful in 24s
ci / build and test (push) Successful in 3m22s
The commit before this one taught a terminal to notice its machine going away.
The file browser had the same defect and three of the same symptoms, and it is
also the screen people leave soonest — so the disconnect work and four things it
was missing arrive together, because they are the same complaint: this screen
knows less about the host than the host does.

◆ THE DISCONNECT HALF, WHICH IS THE OTHER SURFACE OF THE LAST COMMIT.

IsConnected was set at connect and cleared only by the DISCONNECT button. A host
that went away therefore left this screen saying CONNECTED over a session that
was gone, and every action after it failing with the same server message and
nothing saying why they all did.

IRemoteFileStore now carries a latched TransportFailure and a ConnectionLost
event. The latch is the shell's own — read ISshShellSession.TransportFailure for
the argument, which is unchanged. The event is not, and it is the part this
surface needs: a file browser is idle between operations, so without something
raised at the moment the transport fails, nobody finds out until they click. A
bucket implements both and raises neither, which is honest rather than a gap:
S3 is request-per-operation with no connection to lose.

  - THE LISTING STAYS ON SCREEN, and that is the half that makes the rest worth
    having. SftpEntry is a record of what the server said rather than a handle,
    so the pane can go on showing where the user was — which is what RECONNECT
    is offering to put them back into. That needed a new ShowsRemoteContents on
    both heads: every "is there anything here" binding read IsConnected, which
    was right while the only way to stop being connected was to press a button
    that empties the pane, and wrong the moment a session could be lost.

  - RECONNECT re-dials through the ordinary connect path — same host key gate,
    same refusals, same log entry — and then walks back to the directory the
    pane was showing. The path is read off RemotePath rather than captured,
    because the pane already keeps it up to date and a copy is a second thing to
    get wrong. A host wanting a typed password is asked for one rather than
    dialled with an empty box.

  - SessionEndedBar is now one control on both surfaces, with the shell
    resolving which it is drawn over: a terminal has two endings to tell apart
    and a keychain entry to check, a file session has one ending and already
    captured what it would dial. The phone's Files screen has its own copy,
    bound to TransfersViewModel directly, because its DataContext is that rather
    than the shell.

◆ PERMISSIONS: THE PERMS COLUMN STOPS BEING READ-ONLY.

It has been a true fact about a file with nothing to be done about it since it
arrived, and the commonest next act after using this screen was opening a
terminal — a whole second authenticated connection — to chmod what had just been
uploaded.

Nine checkboxes rather than a box to type 755 into, because the mode is already
drawn as -rwxr-xr-x in the column the form was opened from: a who-can-do-what
grid is the same representation the reader is holding, where an octal field asks
them to translate something they can see into something they cannot check. The
octal is printed underneath as it changes, so the two readings check each other.
The EXEC column is headed "enter" over a directory, which is what that bit means
there and the commonest misreading of a POSIX mode. The listing is re-read after
APPLY, because a umask, an ACL or a filesystem mounted without permissions can
all land somewhere other than what was asked for.

Beside it, mode and mtime carried across a transfer — which is what makes an
uploaded deploy.sh arrive executable instead of with the server's umask on it.
THE MODE IS ONLY SENT FROM A PLATFORM THAT HAS ONE. A file on Windows has no
POSIX mode; this screen already says so by leaving the local pane's PERMS column
empty rather than filling it with a plausible -rw-r--r--, and inventing 0644, or
0755 for anything called .sh, would be this client deciding a fact about
somebody's file that nothing on the machine it came from ever said. The
timestamp goes either way, because every platform has one. A store with neither
refuses in its own words and is never asked.

◆ MULTI-SELECT: A TICK IS NOT THE LIST'S SELECTION.

The two answer different questions and the split is the whole design. The
selection is "the row I am looking at", which rename, move and permissions act
on — each takes a form naming one path and is one-at-a-time by construction. The
tick is "the rows I have gathered up", which download, upload and delete take,
and it survives the highlight moving.

With nothing ticked the batch falls back to the selection, which is what keeps
the commonest use of this screen from growing a step — the usual way a
multi-select makes a tool worse. Ticks are released once a set is queued, or a
second press sends everything again.

Deleting several names every path rather than a count, because agreeing to "3
items" is agreeing to a number, and this is the one act on this screen that
nothing walks back. Each goes on its own and a refusal does not stop the rest:
the host turns down a directory that still has something in it, and in a set of
five that must not silently cancel the four it would have removed — nor hide
which ones it did not.

A drawn checkbox rather than ctrl-click, and not for taste: the phone shares
this view model and has neither ctrl nor shift, so a multi-selection has to be a
tap target there whatever the desktop does. One shape on both heads, and a state
somebody can see.

◆ RECURSIVE FOLDERS: THE TREE BECOMES FILES BEFORE THE QUEUE SEES IT.

A directory used to be counted and skipped. It is now walked, and the queue
still knows nothing about trees — which is what keeps every property it has:
each file resumable on its own, each written to a part file and renamed into
place, none able to overwrite anything already there.

The plan is collected whole and then queued, because directories have to exist
before the files that go in them and shortest-first is the only order that
guarantees a parent before its child. It also means a walk refused halfway has
queued nothing yet, so the sentence it produces describes one outcome rather
than an outcome and a queue that half happened.

Links are counted, not followed, in both directions. One pointing at an ancestor
is a walk with no end, and on the remote side there is a second reason: an lstat
listing says a name is a link and not what it leads to, so descending would be a
round trip per entry to find out. Locally that is AttributesToSkip on the one
enumeration that decides what to descend into. A 5000-file ceiling is a backstop
for the accidental drag of a home directory, and it says so rather than
truncating quietly.

The status line grew four more ways to be partly what was asked for, and states
each: gone, refused, left alone, not a file.

◆ EDITING IN PLACE: FETCH, OPEN, WATCH, PUSH BACK.

The round trip this replaces is download, find it, open it, edit, come back,
delete the old one because nothing here overwrites, upload, check the mode
survived.

DELIBERATELY NOT THROUGH THE TRANSFER QUEUE, in either direction. The queue
refuses to overwrite, which is the right rule for a file somebody dragged and
exactly the wrong one for a file they are editing, where replacing the original
is the entire intent. The write-back deletes first: OpenWriteAsync at offset
zero writes over the beginning and leaves any tail that is longer — its own
contract says so — which for a config that got shorter means a file ending in
the back half of its previous version. Deleting is the only truncation this
interface offers, and the mode goes back on afterwards because deleting took it.

A stat before every save, compared against what the server said when the copy
was taken, catches somebody else writing while the file is open — which is how a
config gets silently reverted. There is no merge and no button pretending
otherwise; the three answers offered are the three that exist. Length and
timestamp rather than a digest, because a digest is a second full read of a file
there is otherwise no reason to fetch.

Both platform halves are injected: what opens a .conf is a registry
association, a desktop entry or a Launch Services binding depending on the
desktop, and watching a file is a platform object with its own thread. The
watcher watches the directory and filters the name, because a great many editors
write a temporary file and rename it over the top — which to a watcher pointed
at an inode is the file disappearing. The phone gets neither delegate, so the
button is not live there rather than there and disappointing.

◆ TWO THINGS FOUND ON THE WAY, BOTH WORTH STATING.

The shell suite's inline `post` was not serialising the way a dispatcher does.
Routing TransfersViewModel through it exposed a check-then-add in
OnTransferChanged that two threads turn into two rows for one transfer. Harmless
in production, where the UI thread serialises — the fixture was under-specifying
what it stood in for, and now posts under a lock.

And the edit session replaced its own record with `with` on each save, which
left the watcher holding an instance that was no longer the current one: every
save after the first quietly did nothing. The stamp moves in place now, and the
test saves twice.

◆ WHAT IS VERIFIED.

901 across the five suites this touches, 19 of them new. The layout suite earned
its keep three times over: the batch deletion card's path list overflowed the
204-pixel pane at 120, at 72 and at 56 before 32 held, and the edit strip
overflowed by 131 until the whole strip — rather than the log inside it — was
bounded. Each number in those files is measured and says which failure it came
from, because the next person to add a line to either card will move them again.

What no suite covers is the platform halves of editing: Process.Start with
UseShellExecute and a live FileSystemWatcher are the operating system, and a test
waiting on one would be measuring it. The shell's own half — when a save is
written back, when it is refused, what stopping releases — is covered against a
watcher that fires on demand.

A terminal whose machine rebooted stayed green for ever. Not "went stale and
recovered late" — for ever: the tab claimed CONNECTED, the elapsed timer went
on counting, and the only thing that ever corrected it was closing the
application. That is the defect this fixes, and it turned out to be two
separate failures wearing one symptom.

◆ THE HANG IS IN SSH.NET, AND KEEP-ALIVE ALONE WOULD NOT HAVE FIXED IT.

ShellStream ends a blocked read from exactly two places: its channel being
closed, and the session raising Disconnected. A shell that exits gives the
first. But Session raises Disconnected from one method only — OnDisconnectReceived,
for a server that politely says goodbye — and a socket that simply fails goes
down a different path entirely: RaiseError fires the error event, sets the
disconnecting flag and disposes the socket, without ever raising Disconnected.
So the stream was never disposed, its Monitor.Wait was never pulsed, and the
read blocked until the process ended. The transport was gone, the client knew
the transport was gone, and nothing woke the one thread that was waiting.

That is why the first attempt at a test for this sat at thirty seconds and
failed. Both halves are needed and neither is sufficient:

  - Keep-alive makes the failure HAPPEN. An idle SSH session is a socket
    nobody writes to, and TCP has no way to discover that the far end has gone
    without writing to it — nothing was asked, so nothing could fail. Thirty
    seconds, matching OpenSSH's own ServerAliveInterval examples. It is the
    write that matters and not a reply: SSH_MSG_IGNORE need not be answered,
    so this is traffic rather than a heartbeat with a deadline, and there is
    no timeout invented here to be wrong about a slow link.

  - Disposing the stream from the error handler makes it ARRIVE. Queued to the
    thread pool and not done inline, which is not tidiness: this runs on
    SSH.NET's message-listener thread, and closing a channel waits for the
    server's close — processed by that same thread — so an inline dispose is
    the listener thread waiting on itself.

SFTP gets the keep-alive too. Its operations are request/response and bounded
by ConnectionInfo.Timeout already, so it needs no equivalent wake-up.

◆ exit AND reboot ARE TOLD APART BY A LATCH, BECAUSE THE OBVIOUS WAY IS A RACE.

Wait for the read to end and then ask whether the transport is still up, and
against a real server the answer is wrong about half the time: this was the
only channel on the connection, so sshd hangs up a millisecond after closing
it. By the time anything could ask, the transport is gone either way — and a
poll would report every ordinary `exit` as a dropped connection.

So ISshShellSession.TransportFailure is set at the moment SSH.NET raises the
failure, which its own ordering puts strictly before the disconnect that wakes
the read. A read that has just returned zero consults a settled value: set if
the transport failed, still null if the remote merely closed the channel. The
pump turns that into a TerminalSessionOutcome — RemoteClosed, ConnectionLost,
ClosedLocally — carried on SessionEnded, which used to hand over a session id
and nothing else. A subscriber cannot work this out afterwards; by the time it
hears, there is no transport left to interrogate.

Deliberately no fourth value for "the remote rebooted". Nothing on the wire
distinguishes a reboot from a cable being pulled, and a name this client
cannot check would be a guess dressed as a fact.

◆ WHAT IS DRAWN, AND WHY IT IS NOT DRAWN OVER THE PANE.

The status bar says DISCONNECTED or SHELL EXITED where it used to say NOT
CONNECTED for both — a word that is honest about a tab still dialling and
useless about one whose shell has stopped. Red for the first and grey for the
second: one is a machine that stopped answering and the other is work
finished, and crying wolf on the ordinary end of every session is its own bug.
The tab strip's dot gains the same fourth state, on both heads.

Under the terminal, a strip carrying the reason and two buttons. It takes its
own Auto grid row rather than overlaying the renderer, and that is forced
rather than chosen: the WebView is a native child view composited above
everything Avalonia draws, so the alternative is collapsing the terminal — and
the scrollback is precisely what the user wants to read, because the last
thing the remote said is usually why it went. terminal.js already writes the
same sentence into the pane; this is the copy that does not scroll away.

RECONNECT reuses the tab in place, which is what the word means to somebody
who pressed it: the terminal they were working in comes back, where it was.
It dials through the vault's ordinary connect path, so every refusal — a key
that has left the keychain, an unknown host key, a group default that has
changed since — is decided in the one place that already decides them; what
this adds is which tab the attempt belongs to. The old session is closed as
part of it, because a dead shell still holds an authenticated connection this
process has stopped reading, and its pane still holds an xterm, a scrollback
and a WebGL context, of which a browser hands out about sixteen.

Two refusals it makes rather than pretending: a host reached by typing an
address has no keychain entry to redial, and one that wants a password typed
goes to the keychain with the sheet raised rather than being dialled with an
empty box. Both say so on the strip where the button was pressed, not only in
the vault's status on a screen that surface is not.

TRY AGAIN appears on a refused connection for the same reason, and it is worth
as much: the commonest refusal is a host that was not up yet.

◆ WHAT IS ACTUALLY VERIFIED.

Two tests against a real sshd in a container. `exit` is reported as the remote
closing the session — the one a polling implementation fails, and a fake shell
cannot show it because a fake has no server behind it deciding to hang up. And
a live shell losing its transport is reported as a lost connection, produced
by dialling through a plain TCP relay the test owns and then cutting it; the
container is shared by the collection, so killing sshd was never an option.

The first draft of that second test used LoopbackProxyTests' SOCKS forward and
timed out: disconnecting the carrier of a ForwardedPortDynamic does not close
the loopback socket it accepted. Recorded in the test, because it is a
property of SSH.NET's forwarder rather than of anything here, and it is not
what a dying machine looks like.

What no test reproduces is the waiting. A relay that closes sends a FIN, so
the socket reports itself at once; a machine switched off sends nothing, and
finding that out is the keep-alive's business and the OS's retransmit budget's
— neither of which a test can hurry along without a clock this code does not
own. A reboot is prompt in practice because the machine comes back and RSTs.

Beside those: three pump outcomes, three workspace announcements, and seven
shell-flow tests covering the drop, the clean exit, reuse of the tab, retry
after a refusal, and both ways a reconnect can honestly come to nothing.

Also fixed in passing: SshNetShellSession.IsOpen read ShellStream.CanRead,
which is documented as always true — the stream stays readable after disposal
so buffered output can be drained — so it had answered "yes" for every shell
that ever existed. It reads CanWrite now. And MainWindowViewModel's session-
ended handler moved from Dispatcher.UIThread.Post to the injected post
delegate, which is what makes any of the shell half testable at all; the
remark listing the three unreachable posts is one shorter.

Two things the RPM shipped without, and the reason they arrive together is
that both are the same question — what may this platform ask of the machine,
and what must it not ask of the user.

◆ UPDATES: THIS CLIENT CHECKS AND FETCHES, AND PACKAGEKIT INSTALLS.

ADR 0013 rule 11 said there was no updater at all, and that went too far. It
conflated noticing that a newer build exists with installing it: the second is
what the trust argument is about, and the first is not — a client that checks
a fixed address and tells you what it found has taken no capability from
anybody. Written as a flat refusal, the rule bought its safety by paying a cost
that was avoidable, and the ADR now says so in its own words.

So LinuxUpdateChannel reads the rolling nightly release, compares versions the
way rpm compares them, downloads the package, verifies its digest and hands the
file to PackageKit over gdbus. Polkit asks; the user may say no; nothing is
torn down before the answer, because ApplyingEndsTheProcess is false and the
shell already knows what that means — it is the phone's shape, and declining an
update must not cost somebody their open shells.

Three details that are load-bearing rather than incidental:

  - The comparison is rpmvercmp and not SemVer, because rpm is what will accept
    or refuse the install. Same argument ADR 0014 makes for versionCode. The
    installed side is read out of the rpm database rather than derived from the
    assembly, so the SemVer-to-rpm translation exists in exactly one place. All
    28 expected values in RpmVersionTests came out of rpm itself rather than out
    of a reading of the algorithm.

  - The digest is checked and is not a signature. Velopack verifies its own
    downloads and Android checks a signature; an RPM over HTTPS has neither. The
    manifest names a SHA-256 and a mismatch deletes the file rather than leaving
    something installable-by-hand in the profile directory.

  - ONLY_TRUSTED is cleared, which is what routes the request to polkit's
    package-install-untrusted action. The package is unsigned, so requiring
    trust would fail every update at the last step.

◆ THE DEVICE KEY: SEALED IN THE TPM, BEHIND A PIN THE TPM CHECKS.

ADR 0007's amendment is the bar: a gate inside the process is not a gate. The
key is sealed into a TPM 2.0 keyedhash object whose userAuth comes from a PIN,
so unsealing is a command the chip refuses; the blob is encrypted to the storage
hierarchy and is useless on any other machine; nothing here ever compares a PIN.

The sealed object deliberately carries no NoDA attribute, and that one omission
is the whole reason four digits is enough: every wrong answer advances the TPM's
dictionary-attack counter and the chip stops answering entirely once it trips.
Measured at four wrong tries against a software TPM, after which the correct PIN
gets nothing either. It is asserted by a test rather than left to a reading of
the template, because removing the attribute leaves every other assertion
passing.

This is weaker than Hello and Touch ID and the difference is invisible, so it is
written down in three places rather than smoothed over: those raise their prompt
from inside the platform and this one is a window we draw. The prompt is
deliberately plain for that reason — teaching people that a convincing DodoSSH
PIN box is a system dialog is the one thing this design must not do.

Rejected, each for failing the amendment: the Secret Service API, which has no
per-use consent and is DPAPI's shape exactly; fprintd, which answers a question
and holds nothing, so skipping the call skips the gate; and a polkit-gated root
helper, which would work and puts a privileged component in a package that
installs nothing setuid.

Availability is narrower than "has a TPM": on Fedora /dev/tpmrm0 is root:tss and
desktop users are not in tss, so the ordinary case reports unavailable and keeps
asking for the passphrase. Shipping a udev rule to widen that is refused — it is
the administrator's decision, not an application package's.

◆ WHAT IS ACTUALLY VERIFIED, SINCE THAT IS THE PART THAT USUALLY ISN'T.

This is the only device key store in the repository with real coverage, and it
is only possible because the PIN is a delegate and the TPM is a device: seal,
unseal, wrong PIN, lockout, decline and a foreign blob all run unattended
against a software TPM. Windows and macOS cannot be tested at all — their
prompts block a suite forever, which WindowsDeviceKeyStoreTests records.

TSS.Net's own TcpTpmDevice cannot reach swtpm: it opens the platform socket too
and exchanges a handshake only the Microsoft reference simulator answers, so
Connect() blocks with no error and no timeout. SoftwareTpm speaks the data
channel and nothing else.

The suite also lied once and was fixed: the lockout test trips shared state, and
without a DictionaryAttackLockReset in Dispose every later test got null from a
correct PIN — six of them assert null and passed for entirely the wrong reason.

End to end on a real Fedora 44: a genuine linux-x64 publish packages, installs,
and every DT_NEEDED in the installed tree resolves except liblttng-ust, which is
the one this spec deliberately excludes. What no runner covers is /dev/tpmrm0,
PackageKit and polkit, and Phase 19 grew five checks for exactly those.

Also fixed: the magic-bytes literal picked up raw control characters, which made
LinuxDeviceKeyStore.cs binary to git — no diffs and no line-ending normalisation.

The columns in both panes were fixed pixel widths, and measuring them against
what they actually draw found them wrong at both ends of the range this screen
gets.

◆ MODIFIED WAS TRUNCATED AT EVERY WIDTH THE APPLICATION HAS EVER BEEN DRAWN AT.
It prints a sixteen-character timestamp, which needs 116 pixels, and it had 52.
On a maximised window that read "2026-08" beside a NAME column with four
hundred empty pixels in it. PERMS needs 60 for a ten-character mode and had 48;
SIZE needs 58 for "999.9 GB" and had 56.

◆ AND AT THE SESSION SHELL'S OWN NARROWEST, NAME MEASURED ZERO PIXELS. Twenty
for the glyph plus 56+52+48 for the numbers is 176 of the 180 a row has, so the
remote pane drew sizes, timestamps and modes for rows whose names were not on
screen at all. That is the same fault as the one above rather than a second
one: the numbers were picked for the narrow budget, could not have fitted their
own content there, and never grew anywhere else.

Star columns with a MaxWidth answer both, because the cap is what makes "share
the width" mean the right thing at each end. Wide, the three numeric columns
stop growing at what their text needs and NAME keeps every remaining pixel.
Narrow, nothing carries a MinWidth to overflow with, so all four give ground
together and NAME — weighted heaviest — is the last to run out. MODIFIED takes
the extra weight so it reaches its cap first, being the widest content and the
column most often actually read; the local pane's NAME carries the remote's
PERMS weight folded into it, which is what makes SIZE and MODIFIED come out the
same width on both sides of the arrow column. Timestamps.Format already argued
that both panes write a time the same way so the two can be read against each
other, and two different widths would have made that argument for nothing.

◆ THE HEADINGS RAN TOGETHER, and that was visible as one word: SIZE ended on
the pixel MODIFIED began at, so the row read "SIZEMODIFIED". They are
right-aligned in their own columns, so the gap has to come from a left margin
on each — which does not move the label and does stop the column before it
reaching this one. The three now carry one, and ellipsize rather than clip
where even the label has no room.

◆ TWO PLACEHOLDERS WERE CUT OFF MID-WORD, which reads as a rendering fault
rather than as a hint. MKDIR's box drew "new directo" — 101 pixels of text in
74 pixels of room — and says "directory" now, since the button beside it
carries the "new" half already. The pane header's path box drew a path ending
mid-segment at the narrow budget and says "path": the only time that
placeholder shows is on a pane with nothing connected, where the box is
disabled and the invitation below is doing the explaining, and what the box is
for is in its tooltip where there is room for it.

FOUR COPIES OF THE COLUMN DEFINITIONS, one heading row and one row template per
pane. Avalonia cannot share a ColumnDefinitions instance between two Grids —
each mutates its own computed sizes — and SharedSizeGroup only applies to Auto
columns, so what catches a copy that drifts is measurement rather than
discipline: every cell is held against the width its own text needs when
unconstrained, the headings against each other, and NAME against zero at the
narrowest budget. Nothing asserts a number this file also wrote down, which is
the failure mode a test of a layout most easily has.

The roomy end is measured at the width a maximised 1843-pixel window leaves,
which is where this was reported from; LayoutHarness.SessionScreenWidth cannot
express it because that constant is pinned to the window's minimum, so the
arithmetic is spelled out beside the test that uses it.

Three things the file browser could not do. Somewhere to go had to be walked
to, a file that landed under the wrong name could only be removed and sent
again, and the listing went on showing the directory as it was before this
application put something in it.

◆ THE PATH IS A BOX NOW, not a TextBlock printing where the pane was. A
breadcrumb only reaches what is under the directory already listed, so crossing
a host's filesystem cost a click and a round trip a level, and a path somebody
already knew could not be entered at all. Enter goes; Escape puts back what the
pane is really showing.

What is typed may be absolute, relative to the directory showing, or start at
~ — the four shapes a shell takes, because somebody typing into a box is typing
what they would type into a shell. SftpPath.Resolve turns all of them into one
absolute path, and it resolves them here rather than handing a relative path to
the server: the server would resolve it against the session's own working
directory, which is not necessarily the directory the breadcrumb above the box
is showing. `..` is collapsed textually, which differs from cd through a
symbolic link; the alternative is a realpath round trip before anything lists.

The box holds its own value rather than RemotePath itself. Binding it straight
to the path would navigate on every keystroke — `/`, then `/v`, then `/va` — a
round trip and a failed listing per character. Every other way of moving writes
the real path back into it; a refused listing deliberately does not, because
the path that did not resolve is the one worth having in front of you.

◆ RENAME AND MOVE, and DELETE moves to join them. It had been sitting in the
pane header beside UP and REFRESH — two things that move the pane and one that
destroys a file, in one row — and the three that act on the selected row are
now together in a row of their own, under the name of the row they are about.

One SFTP rename underneath both new operations and two separate questions on
the screen, because the answer is a different kind of thing each time: a rename
takes a name and must not take a path, a move takes a directory and must not
take a name. One box asking for a destination path would be fewer controls and
a worse question — the two mistakes it invites are exactly the ones the split
makes impossible. Each form opens on the answer that changes nothing, so what
gets edited is the half somebody came to change.

Three refusals are made here, and they are the ones a server's message would
not explain: a separator in a name (no such file, about a directory nobody
meant to name), a destination equal to the source (success, and a file that did
not move), and a directory into itself (EINVAL, true and useless). Everything
else is the server's — a name already taken, a path that is not there, a mount
that cannot be crossed — and arrives in the status line in its own words.
Neither is painted in the deletion card's red: a rename is undone by renaming
back, and spending that red twice makes it stop meaning anything.

◆ THE LISTING REFRESHES ITSELF when a transfer lands in it. Both panes, since
an upload lands on the host and a download lands here and either leaves the
pane that is showing that directory a step behind. Only the directory actually
on screen: a queue moving a hundred files elsewhere must not be a round trip
per file for a listing nobody is looking at.

It waits rather than interrupting. Another operation running would have two
listings racing for one collection, and re-listing under an open question is
how the row somebody answered about stops being the row that gets acted on — so
the staleness is remembered and settled at the end of the operation or when the
question is dismissed. It says nothing either way: nobody asked for it, and the
status line at that moment is carrying the news about the transfer. The
selection survives, re-found by path, which is what makes an unasked-for
refresh safe to run under somebody's pointer at all.

◆ THE LAYOUT SUITE FOUND A REAL FAULT and the fix is where the height goes. The
rename form did not fit the 204 pixels the session shell's own sidebar leaves
this pane — MKDIR and the listing were pushed off the bottom. The form is
shorter now (the placeholder says what the box wants, so there is no field
label above it), and the item row and the breadcrumb step aside while any of
the three questions is up, which is what the phone head already did with its
own buttons.

Measuring also settled something the markup had been claiming and is not true:
at that width the listing collapses to nothing under any of the three cards,
the deletion card included, and has done since the sidebar arrived. So "the row
it is about is still on screen" is retired from the deletion card's remark, and
the full path each card carries is what identifies the row instead. Recorded
where it is drawn rather than left to be rediscovered.

TESTS. SftpPath.Resolve gets the four shapes, ~ with and without a home to
expand it to, a blank box, and climbing past the root. ShellFlowTests gets nine
against a session that records what it was asked to do — which path was
renamed, which directories were listed — rather than against the sentence this
code writes about itself: the path box absolute and relative, rename in place,
the separator refusal, a move by relative path, the no-op refusal, the three
questions displacing each other, and the three rules the automatic refresh
follows. The local half is in TransferQueueingTests, where a real folder
answers. Two new shapes are measured, and the deletion card's own measurement
moves to the connected state — the only state it can be asked in, and the
narrow one.

What the tests cannot reach is in docs/manual-checks.md as phase 2b: a real
server's cross-device and name-taken refusals, and a soft keyboard, which is
why the phone's path box has a GO button rather than trusting whatever the IME
decided to draw on its return key.

ci / desktop nightly (pull_request) Skipped
ci / api image (pull_request) Skipped
ci / android head (pull_request) Failing after 6s
Ctrl+K reaches every vault the session holds a key for — that is deliberate,
and it is what makes the palette worth opening from anywhere. What it did not
do was say where a result came from. A team and a person who both call a
machine prod-db got two identical rows, and Enter took whichever the ranking
happened to put first: the same three characters, two different machines,
depending on nothing anybody could see.

Nothing new is computed for this. HostRowViewModel.VaultBadge has been filled
in since the host list learned to span vaults, and it is already drawn on the
hosts board, the keychain, the snippets list and the known-hosts pane. The
palette was the one list reaching across every vault that did not print it.

◆ THE VAULT IS THE LAST OF THE FOUR RANKS, AND THAT IS THE POINT. A vault name
is the widest reading of the three the palette had: one word matches every host
in that vault at once, where a name or an address matches one machine. So it
sits behind name-starts-with, name-contains and address — otherwise typing a
machine's name would bury it under everybody else's.

It matches on HasVaultBadge rather than on VaultName, so the search only ever
matches what the row actually shows. A session holding one vault prints no
vault on any row, and matching it there would answer "personal" with the entire
keychain, ranked behind nothing and explained by nothing on screen.

In the row, the right-hand column becomes two lines against the two on the
left, in the same order: what this is above, how it is reached below. With one
vault the badge is empty, the line collapses, and the kind word stays centred
exactly where it was. The name is capped and ellipsised because that column is
Auto-sized — a long vault name would otherwise take its width out of the host
name beside it.

Three tests, one per claim. VaultSharingTests puts platform-gateway in the
personal vault and prod-db in "Platform secrets" and types "platform": both come
back, the gateway first. ShellFlowTests types the personal vault's own name into
a one-vault session and gets nothing. QuickConnectTests is the markup's half —
the shared vault's row draws PLATFORM SECRETS, and a one-vault row draws no
vault at all — with the shared vault put into the session through the layout
suite's own StubTeamServer, as the settings pages' suite does it.

449 App tests and 155 layout tests pass. Both suites were run with
-p:NuGetAudit=false: SSH.NET 2025.1.0 has picked up GHSA-q939-rpr3-3284 and
NU1903 fails restore repo-wide, which predates this branch and is nothing to do
with it. No package or lock file is touched here.

Three things one pass over the shell's chrome turned up, none of them related
to the others beyond having been looked at together.

◆ A PALE STRIP ACROSS THE TOP OF THE WINDOW ON WINDOWS, and it is not this
application's titlebar. Avalonia's Win32 backend gives a BorderOnly window
WS_BORDER | WS_THICKFRAME and then calls DwmExtendFrameIntoClientArea with
one-pixel margins on all four sides — read out of WindowImpl.UpdateWindowProperties
in 12.1.1 rather than guessed at. So DWM owns a hairline of every edge and fills
it with the system's caption and border colours, which follow the user's
personalisation settings: with "show accent colour on title bars and window
borders" on, that is blue against a near-black shell. Nothing in the visual tree
painted those pixels, which is why nothing in the visual tree could cover them.

NativeWindowFrame sets DWMWA_BORDER_COLOR and DWMWA_CAPTION_COLOR to the
window's own Background, so the hairline still exists — the resize grip is on
it, the drop shadow hangs off it — and cannot be seen. Deliberately not
DWMWA_COLOR_NONE, which removes the border outright and leaves a near-black
window with no edge at all on a dark desktop. Windows 10 gets the dark-mode
attribute and nothing else, because the two colour attributes are Windows 11
and DwmSetWindowAttribute simply answers E_INVALIDARG there.

Called from OnOpened, not the constructor: there is no platform handle until
the window is shown, and calling early is a silent no-op — which looks exactly
like a fix that does not work.

Verified on screen on Windows 11.

◆ THE HOSTS HEADER SAT A STEP LEFT OF AND ABOVE EVERY OTHER SCREEN'S. Keychain,
Snips, Logs and Pins all frame their content with Margin="26"; Hosts was on 16
a side and 20 on top. It is 26 all round now, stated per row rather than once on
the root, because the board's ScrollViewer is deliberately full-bleed so that
its scrollbar rides the pane's edge, and because a root margin would also inset
the drawer, which draws its own.

That cost the cards ten pixels, and the layout suite is what said so:
TheHostsGridKeepsTwoColumnsAtTheMinimumWithTheDrawerOpen failed, because
Border.tile's 224 was derived from the board's old 16-pixel margins and the grid
quietly collapses to one column at exactly the size this application guarantees.
224 becomes 214, with the arithmetic in App.axaml rewritten — it had also gone
stale in a way that hid itself, still citing the 1016 minimum and 190 rail from
before v5b, whose two changes happened to cancel.

◆ PINS LEAVES THE RAIL, and only the rail. KnownHostsScreen is still built and
still one click away, from "Host keys" on the Keys screen's own header, which
was always the second way in. The row was kept through v5b on the grounds that
the mock has no screen for approved host keys — a reason for the screen to
exist, and never a reason for a rail entry once the keychain had a door to the
same place. Two rows landing on one screen is a rail that has to be read twice.
MainWindowViewModel.IsKnownHostsShowing stays: it names a real shell state and
ShellFlowTests still asserts on it.

design-import-gaps.md recorded that row as a deliberate deviation and
manual-checks.md Phase 1.1 walked the rail entry by entry; both are corrected,
and the manual check now reaches the screen the way a user would.

The layout suite's rail row count moves from six to five with it.

153 layout tests and 446 shell tests pass. The frame is confirmed by eye; the
Hosts inset and the rail are covered by the layout suite but were not seen
running, because the instance launched to check them came up locked.

Seven things reported from a day's use of v5b's session shell, and they are one
commit because five of them are the same complaint from different angles: the
window spends too much of itself on chrome describing the session, and the parts
that are not chrome do not behave.

◆ THE HOST HEADER IS GONE, and that is a deliberate departure from the design.

Terminal.dc.html and SFTP.dc.html both draw a 60-pixel row above the pane: the
address on the left, a cross-surface button on the right. Both facts are worth
having and the strip they sat in was not — the tab already names the host, and a
full-width bar repeating it was the cheapest 60 pixels in the layout to give
back. The address is now the first line of the sidebar and the button is
stretched across the column under it, so nothing is lost and the pane is taller.

Which word that button carries and which command it runs used to be handed in
from the two usage sites in MainWindow.axaml, because the control was drawn
twice. One sidebar cannot do that, so SessionCrossSurfaceLabel and
OpenOtherSurfaceCommand resolve it in the shell — the same place SessionAddress
already decides which surface's fact to read. The two directions underneath are
untouched: SelectFilesHostAsync for a tab's host, OpenTerminalForFilesHostAsync
for a fresh terminal at whatever SFTP has open.

SessionHeader.axaml is deleted rather than left unused, and LayoutHarness stops
subtracting its 60 pixels from every session screen's budget — the same
treatment the retired window-wide tab strip got, and for the same reason: a
constant for chrome nobody draws is a suite quietly measuring the wrong
rectangle.

◆ AND THE SIDEBAR CLOSES, which the design has no state for at all.

300 pixels of an 1081-pixel minimum is a great deal to spend on a list that is
often two rows long. The column now folds to a 34-pixel rail carrying the
chevron that brings it back — a rail rather than nothing, because a panel that
vanishes leaving no trace is one people report as lost rather than as closed.
Both states live in the one control and swap on IsSessionSidebarOpen, so
MainWindow's own "Auto" column takes whichever width is showing without knowing
the state exists.

Written through to ClientSettings.SessionSidebarOpen rather than held for the
session. It is a decision about how much of the window a terminal gets, and one
that had to be made again on every launch would not really be on offer.

---- THE FOUR SMALLER ONES ----

A SNIP LANDED IN A TERMINAL NOBODY COULD TYPE AT, and looked selected when it
got there. Two causes with nothing in common. The click moved Win32 focus onto
the sidebar row, and term.focus() in the page cannot take it back — only the
host can, so the shell raises TerminalFocusRequested and the window answers with
the same posted focus every other path here uses. The highlight was bash: xterm
wraps a paste in bracketed-paste markers, readline marks what arrives inside
them as an active region, and it stays in reverse video until the next
keystroke. Right for a clipboard paste, wrong for a snippet picked off a
sidebar. Single-line snips are typed rather than pasted now, which needs no
markers; multi-line still pastes, because "runs three commands unasked" is the
worse of the two failures and the markers are the whole of what prevents it.

A BLACK BAR UNDER THE TERMINAL, on Windows. xterm.css paints its scrolling
viewport #000 — its own comment explains why, and it is a macOS scrollbar
concern. Everywhere else that black is covered by the rows, except along the
bottom: the fit addon floors the row count, so the remainder below the last
whole row is bare viewport, up to a line tall, against this page's #171a26. The
light square at its right-hand end is where WebView2's classic scrollbar corner
lands. The viewport is repainted in the page's own background, and the scrollbar
with it — thin and in these colours rather than a grey Windows channel down the
side of a near-black terminal, and kept rather than hidden, because a surface
that scrolls with no sign that it does is worse than a quiet bar.

THE PINS ROW DREW A TOFU BOX. U+E946 is not in the embedded Material Icons face
at all — that file is the 2019 build and its cmap skips E944 and E946 — so the
rail's Pins row and the hosts screen's own pin badge have both been drawing a
missing-glyph rectangle since v5b picked the codepoint. push_pin in that vintage
is U+F10D, verified against the file rather than against a codepoints table for
a later release of the font. Every other icon codepoint in the repository was
audited the same way; this was the only miss.

THE KBD CHIP CUT THE CHORD IN HALF. 34 pixels is the design's width for a chip
reading ⌘K, and this build substitutes CTRL K — six characters and a space,
wider than 34 at 10.5 mono. MinWidth and padding instead, so the design's
footprint survives for the day this face has a ⌘ to draw.

---- AND THE POPOVER UNDER THE USER CHIP ----

Reported as not matching the design, and it was not: Button.poprow set a corner
radius and a padding and never touched the Background, so every row wore the
Fluent theme's own #33FFFFFF button fill. Six raised pills stacked in a menu the
design draws as six lines of text — and the hover rule underneath was already
correct and simply invisible against a fill that never went away. Set on the
ContentPresenter as well as on the Button, the same as Button.flat, because the
theme binds its brush there and a Background set only on the control loses to
it. The panel itself gets this window's own radius-12 card treatment through a
FlyoutPresenter class rather than by widening the shared context-menu rule, and
Vaults and Preferences stop being drawn one step dimmer than Settings and
Logout, which read as two disabled entries in a menu of five live ones.

---- WHAT PROVES IT ----

Three tests in the layout suite, two of them checked against the defect they
describe: the popover row's resting fill (fails with #33ffffff without the
style), and the kbd chip against the natural width of its own text, measured on
a detached copy because a TextBlock's DesiredSize is already clipped to what it
was given and reports 34 inside a 34-pixel chip either way. SessionSidebarTests
is new — the sidebar has never been laid out by a test, and it now holds a
string of unbounded length beside a button that has to stay clickable. In the
shell suite: the cross-surface row in both directions, the closed state
surviving to disk, and the focus request being made when a snip lands and not
made when it does not.

The connecting card set its status string once, when the tab was created, and
never touched it again. Every connection therefore looked identical from the
outside: one three seconds into a key exchange, one waiting out a fifteen-second
timeout against a machine that is asleep, and one that had hung all drew the
same "connecting…". The card now draws the five steps of getting there, each lit
at the moment the handshake reports reaching it, over an amber track that fills
as they finish.

◆ NOTHING ON THE LIST IS INVENTED. Every row changes state because a layer below
it said so, at the instant the thing it names actually began.

That is the whole reason it is worth showing, and it is why most of this commit
is plumbing rather than XAML: there was no progress reporting anywhere in the
stack to hook a step list onto, and a card animating plausible progress would
have been indistinguishable from one that had stopped receiving any.

SshConnectionPhase names four phases and deliberately not more. SSH.NET runs the
entire handshake inside one ConnectAsync and raises exactly one event from the
middle of it — HostKeyReceived, once the key exchange has produced a key to show
— so that event is the only interior moment there is to report. Everything
before it is Reaching and everything after it is Authenticating. A fifth phase
in that assembly would have to be a timer, so there is not one. OpeningShell is
reported by TerminalWorkspace instead, because that is where it happens: the
factory's work ends with an authenticated connection, and asking for a
pseudo-terminal on one is a separate round trip. The SFTP path passes null — a
second connection opened behind an already-open shell has nobody watching a step
list for it.

The card's fifth step, "Starting the terminal", is the renderer wait and lives
in the shell rather than in the SSH assembly, which has never heard of a
renderer. On the first connection after a cold start it is a real wait with a
real failure mode of its own — a missing WebView2 runtime — so a list that began
at "reaching the host" would leave the one wait most likely to hang unnamed.

Amber for the step in flight, and that follows the palette's rule rather than
bending it. Green is what is true and purple is what you can press; a step still
happening is neither, and it is exactly the caveat-worth-reading that amber
exists for. Steps behind it go green as they become true. Nothing animates,
which is the argument TransfersScreen.axaml already makes for its own track,
reaching a screen with far more reason to want a spinner: a spinner is furniture
invented to fill a state nobody measured, and these states are measured, so the
track fills to what has finished and then waits there.

A refusal keeps the step it stopped on, in red, with the ones behind it still
green. That is the half a progress bar could not do, and it is the difference
between "that host is not there" and "that host is there and would not have me"
— a question the reason sentence alone frequently does not settle.

The strip's dot goes amber while a tab is connecting, on both heads. It was
grey, and so is a tab whose shell has exited: the two states in that strip with
the least in common, one worth waiting for and one over. PhoneShell's own
comment already recorded half of this — the dot stopped being green before
anything had answered — and this is the other half.

Progress is raised inline rather than through System.Progress<T>, which captures
whatever synchronisation context it was constructed on and posts to it. That
reads like a convenience and is really a second place the marshalling decision
gets made: silently, differently under a test with no context, and out of order
with respect to the failure that follows a phase. The shell marshals once, in
one handler, through a new optional post parameter on MainWindowViewModel — the
same seam TransfersViewModel already uses, and for the reason its own remark
gives. The three Dispatcher.UIThread.Post calls that predate it are the ones
this suite's comments record as out of reach; they are left alone rather than
swept in here.

Both heads draw the list. They differ in one place: Phone.axaml's mono class
sets a colour and a size along with the family, so the caption rule names its
own family instead of composing the two and asking two rules for one Foreground.
The desktop's mono sets the family alone, which is why ConnectingCard does
compose them. Each head also gains SHOW LOGS beside the button that gives up —
the step list is this attempt and the log is every other one, which is what a
connection taking too long actually raises.

Seven tests, and the two that matter most run against the container rather than
a fake: a real handshake reports its phases in order, and a host-key refusal
never claims to have authenticated. A fake asserting what it was written to
assert would have established nothing about either. The rest cover the tab
advancing while the connection is gated, the step a refusal stops on, and a
phase reported after the user has given up on the tab. 1,861 tests, none
failing.

The Android head's layout is not verified by anything. It compiles, and
compiled bindings mean every new binding path resolves, but that project is not
in DodoSSH.slnx, there is no test project for it and no device here — so unlike
the desktop card, whose shapes the layout harness measures, these rows have not
been drawn. Vertical fit is reasoned, not observed.

The authentication picker has listed saved credentials since they existed, but
making one meant leaving a half-typed host for the keychain screen and coming
back to find it gone. On the phone it was worse than a detour: that head has no
credential editor at all, so it could bind a host to a credential and never
produce one. + NEW CREDENTIAL opens a card under the picker — name, optional
username, password, notes — and ADD writes it and binds the host in one step.

A button beside the picker rather than an entry inside it. Every row of that
list is a binding a host can have, and "make a new one" is an action: as an
entry it would sit in the box afterwards describing a state no host can be in,
and cancelling the form would leave the picker showing it.

It carries its own five fields rather than reusing the keychain editor's, and
that is the load-bearing part. IsEditingCredential is what AVaultEditorIsInTheWay
asks about, so sharing it would have made the whole Vault screen refuse to open
an editor while this card sat open on the Hosts screen, with a status line
naming a form the user cannot see on a screen they are not looking at — the
exact failure that guard was split in two to end. A test pins it.

It writes to the keychain immediately, unlike every other field in this editor,
because a credential is a shared item with an id and a host can only name an id
that exists. The consequence is honest rather than hidden and the hint says so:
a credential added this way outlives a cancelled host edit. What was still being
typed does not — every path that closes the host editor clears the form, and one
of those fields is a password.

The binding is written before the reload rather than after it. RefreshOpenEditors
rebuilds this picker and then restores it from the editor's own selection, so
setting it first is what survives the pass, and by the time it is read
ReloadCredentialsAsync has put the matching entry in the list to land on.

A name already taken is duplicated, not reused, and that is a deliberate parting
from the new-tag box six lines further down which offers the existing tag
instead. Two tags called "staging" are one intention spelled twice; two
credentials called "root" are two different passwords, and quietly binding the
host to whichever was there already would authenticate it as an account nobody
chose. A duplicate label in the picker is the smaller problem.

Into editingHostVaultId, so the credential lands wherever the host is being
sealed and everybody who can read the host can read what it authenticates with.
Stricter than the tag path — which files into the active vault and is recorded
as a gap in docs/design-import-gaps.md — and it can be, because this picker
lists credentials from every readable vault rather than one.

Five flow tests cover the bind-through-reload path, the cancel semantics on both
the saved credential and the abandoned one, the cross-screen guard, the
duplicate name and the empty-password refusal. The layout test is separate and
necessary: the card is collapsed until somebody presses the button, so a harness
driven by the default state draws none of it, and TheHostDrawerFitsWithTheHostEditorOpen
would have gone on passing over a card that blew the column. 1,854 tests, none
failing.

TextTrimming only acts when measure hands the block a finite width, and a
horizontal StackPanel never does — it measures every child at infinity and an
Auto grid column passes the full answer on. So both SFTP pane headers grew
with their path, and a directory deep enough pushed the header's own icon
buttons past the window's edge at the session shell's 472-pixel budget.

The layout suite has said so on every CI run since v5b landed, and nowhere
else: the runner's per-job HOME is a 46-character path, which is what the
local pane opens on, and every developer machine's short profile path left
the same test green. The path sits alone in the star column now — bounded
width, working ellipsis — and the narrowest-budget test pins both panes to
sixty-character paths so the question is asked on every machine alike;
against the old markup that test fails on Windows too.

The v5b design's own row: the negotiated cipher, then the host key's algorithm

beside CONNECTED — on both surfaces, off MainWindowViewModel's surface-aware
SessionCipher and SessionIdentityText, the same shape SessionAddress set.

The identity's name comes out of TryBuildAuthentication, the one resolution
point that always had it in scope and always threw it away; it rides
HostAuthentication to the tab and to the SFTP connect alike. Three deviations,
recorded in the gaps doc: the algorithm prints as negotiated rather than
shortened, the run is plain text because no pin-details modal exists for an
open session, and a typed password shows the algorithm alone — there is no
item behind the dot. A dead terminal tab keeps its facts for the scrollback
still on screen; an SFTP disconnect, with no scrollback, clears them.

Ticking "Connect through the server relay" moved the host's address and port out of the encrypted payload
into plaintext columns on the server — the single deliberate privacy concession in the design, per ADR 0004
— and then the client dialled the address directly, exactly as it does with the box clear. VaultViewModel
builds SshConnectionRequest(hostname, port, username, credential) and nothing on this side reads
RelayEnabled at all. The connection failed the way it always had, for a machine the laptop could not reach,
with nothing saying the box had done nothing.

The server half is built and shipped: tickets, the WebSocket, the deny list, the CHECK constraint that
enforces a non-null address for a relay-enabled host. What does not exist is the client's path to it, so
this is an unfinished feature rather than a broken one — but the control in front of it was collecting the
cost of the finished version.

Both heads now say so, in the label and in the first sentence of the paragraph under it. Not disabled, and
that is the one decision here worth stating: a host somebody has already ticked has to be able to lose the
flag, and a control greyed out with the concession switched on would trap it there. Tickable and honest
beats untickable and stuck.

This is step 0 of docs/reaching-a-host-you-cannot-dial.md, and the only step of it that should ship alone —
the sentence is written to be deleted when the bridge lands.

VERIFIED. Build clean, 112 layout tests. The drawer's paragraph is longer than it was and the host editor is
measured with the drawer open at the window's minimum, so the wrap is held inside the column rather than
assumed to fit.

jaap-jan 88809f0d66 Stop the docs claiming absences that have since been built
An audit of README.md, the seven docs and the fourteen ADRs against the code, looking for what is described
as absent or planned. Most of it held. What did not is here, and it clusters: every stale claim but one is
downstream of the settings file arriving without this document noticing.

design-import-gaps said the client has no preferences store and writes exactly two files. It writes three —
ClientSettings is in settings.json beside the cache — and two preferences are saved through it. From that
one error followed four more: the terminal font size row said "fixed at the renderer's 13px" when it has
been 8 to 32 from a screen and three chords for some time; the transfer-resume row and the per-host last
directory row both blamed a store that now exists, when what they actually want is a table and a scalar file
is the wrong shape for one; and the Preferences table asserted no preference could be saved at all.

It also said TerminalServerOpcode has four values and none carries an option. It has eight, and one of them
is FontSize — which is the interesting part rather than a counting error, because that opcode is the proof
that the frame these rows say is missing can be built. The rows now say what each one would actually take,
which for three of the four is a setting, an opcode and a control, and for the Backspace row is a reason:
which byte backspace sends is a fact about the remote's stty, so a client-side switch fixes a mismatch by
hiding it.

THE SAME TWO ERRORS WERE SHIPPED IN THE INTERFACE. The preferences screen carries a NOT BUILT YET list, so
that what the screen does not do is as legible as what it does — and it said terminal size was hard-coded a
hundred lines below a working size control, and said there is one release channel a month after the nightly
shipped. A list of absences is only worth having if it is true, and a screen contradicting itself in the
same scroll is worse than no list. Both lines are corrected rather than removed: the first now says which
three of the four are genuinely hard-coded, and the second says what is actually missing, which is a way to
change channel from inside the application rather than by installing the other build.

docs/adding-hosts-on-the-phone.md is deleted. It was a work plan whose own header says "Status: built. All
six steps." — nothing links to it, and the decisions it records are in the code it produced, including the
one it is proudest of: HostSecret.AsksForPassword carries its own remark on why naming neither binding had
to stop meaning "ask me". What was left was step ordering and per-test instructions for work that shipped.
Git keeps it.

crypto.md is deliberately untouched. It is normative and frozen, and its claims are about the DSH1 format
rather than about this build — including the one that reads oddly next to the code, that a passphrase is
one of four ways to open a vault. Under the spec it is. What is missing is a statement about what this
build can open, and that belongs beside the spec rather than inside it; see
docs/unlocking-without-the-passphrase.md.

VERIFIED. Build clean, 112 layout tests, 354 app tests. The preferences screen is measured by the layout
suite, so the longer copy is held inside the window at the minimum size rather than assumed to fit.

jaap-jan 507cd9ff88 Choose more than one host card on the desktop, the way the phone already can
The chosen-hosts set has been in VaultViewModel since the phone's connect card became a contextual action
bar: a set of entity ids, a tick on the row, and seven things that can be done to it. Only one head could
fill it. The desktop's grid answered a press with one selection — the card the drawer, CONNECT and the
context menu are about — so filing eleven imported machines under a heading was eleven drags, and clearing
out a vault was eleven rounds of the deletion question.

So the pointer gets three ways into the same set. Ctrl-clicks a card to tick it, Shift-clicks to tick the run
between the anchor and the card, and drags a band out over the space between and below the cards to tick
everything it touches. Esc, CLEAR, a plain click on a card and a click on the empty space each drop it, and
Ctrl+A takes every card being drawn — VisibleHosts, so with something in the find box that is the ones on
screen and not the ones it is hiding, which is the version of that shortcut whose result can be checked
before Delete is pressed.

TWO SELECTIONS ON ONE SCREEN, AND KEEPING THEM FROM DISAGREEING IS MOST OF THE CHANGE. Ctrl and Shift are
answered on the tunnel and marked handled, so the ListBox never moves its own mark onto the card: a
Ctrl-click that also selected would light the card it had just unticked and open the drawer on a machine
somebody is removing from a set. A plain press drops the set unless it lands on a ticked card, and that case
is deferred to the release, because the press may be the start of a drag of all of it. After any ordinary
click exactly one card is in play, which is what makes every command on the screen unambiguous again.

The context menu is where the seven live, and it is one markup with two halves gated on IsChoosingHosts.
Connect, Browse files and Edit… are drawn only for a single ticked host, as the phone's sheet collapses them
and for the same reason; the other four read better for a count. A right click on a card outside the set
drops the set first, so a Delete… about the card under the pointer can never be offered while six sit ticked
behind the menu — the same rule OnContextRequested has always enforced for the selection, reached from the
other direction. No bar of buttons: the phone raises one because it has no other way to hold seven entries,
and a strip repeating a menu that already exists would be a second home for the wording that matters most.
What the desktop gains instead is a count beside the HOSTS heading, CLEAR, and a sentence saying where the
actions are.

A drag that starts on a ticked card carries every ticked card. The payload is a list rather than a row now,
and a drop of more than one goes through FileChosenHostsUnder, which makes the refusals once — an open
editor, and a group belonging to one keychain — and reports a count instead of forty status lines. Moving
whichever card the pointer happened to be holding and leaving the other five where they are is a gesture
that quietly does a fraction of what it looks like it does, and the five left behind look filed.

The three panels the set's actions raise had never been drawn in a window: the vault picker with its key
question, the group picker, and the deletion question. All three sit above the grid rather than over it,
which is the arrangement the GROUPS section and the phone's list already use and for the reason written
there — the ticked cards are the information the question exists to give, so the grid shortens instead.

A DEFECT FOUND BEHIND IT, AND IT WAS ALREADY LIVE ON THE PHONE. The deletion question names a count and the
run that answers it reads the set again, and nothing kept the two the same set: the panel is deliberately
above a live list, so one more tick between "Delete these 6 hosts?" and pressing DELETE deleted seven, with
the seventh named in nothing the user had read. It needed a deliberate act on a phone and a second's work
with a band, which is what turned it up. VaultViewModel now remembers which hosts the question was asked
about and drops the question when the set stops being them — the question rather than the set, because what
somebody has just chosen is what they meant. It also covers the case nobody performs: a colleague's deletion
arriving mid-question and shrinking the set under it.

VERIFIED. 354 tests in App.Tests and 111 in App.Layout.Tests, build clean, no new warnings. Six gesture tests
drive real pointer and key input through the headless window — the modifier click and what it must not do to
the selection, the run and its re-measurement from the anchor, the band and the click that drops the set,
Ctrl+A under a filter, and the menu's two halves — plus a DragOver carrying two hosts. Four layout tests
measure the strip and the three panels at the window's minimum; the vault panel binds a key to its host
first, or it would measure the short shape and certify the tall one. Two flow tests cover the multi-drop's
write and its refusal, and the deletion question dropping itself.

manual-checks gains 7.6a for dragging a set, which no test can see for the reason 7.6 gives, and 7.7a for the
gestures — the rectangle actually being painted and the tick and the fill being legible together are the two
things the harness cannot look at.

jaap-jan 36b8a23020 Give the update banner the view model it is typed to
The banner has never worked. It went into MainWindow's fourth row with no data
context of its own, so it inherited the shell's — and it is the one control in
that file typed to a screen's view model rather than to MainWindowViewModel,
because it is the only one with a layout suite that hosts it over UpdateViewModel
alone. Compiled bindings type-check against x:DataType at runtime, so every
binding inside it resolved against the wrong object and failed the way a compiled
binding does: quietly. No headline, and DismissBannerCommand and RestartNowCommand
both null.

A button with a null command is enabled, hovers, depresses and does nothing, which
is why this looked like a hit-testing problem and why the WebView was the first
suspect. It is not one. The strip is a sibling row for the reason the occlusion
rule gives and that arrangement is correct — the terminal's rectangle is never
covered, only shortened. What was actually on offer was an announcement that an
update had been downloaded, with two buttons that refused to install it and no
way to make it go away either. The preferences screen's RESTART NOW worked
throughout, because it binds Updates.RestartNowCommand from the shell's own
context, which is the contrast that pins the cause.

The context is set on the banner itself and IsVisible loses its Updates. prefix
with it, because a data context on an element resolves that element's other
bindings too — the rule the page area's wrappers upstairs exist to work around.
Those wrappers are needed because IsHostsScreen and its siblings belong to the
shell; IsBannerShowing belongs to the banner's own view model, so there is nothing
to wrap here.

Neither existing suite could have caught it. A layout test supplies the data
context it is measuring, which is exactly the assumption that was wrong, and the
shell suite has no visual tree — its project file already says it does not cover
whether the XAML binds to the right names. So the new test asserts the wiring
rather than the layout: a real shell over the ready-update fake, MainWindow
constructed and never shown, and the banner asked what context it got, whether it
is visible and whether RESTART NOW carries a command. Checked failing with the one
attribute removed. Constructing the window is safe where showing it is not, and
nothing here needs it shown: a data context propagates when it is set, not when
the tree is measured.

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-jan 185790fb14 Let a key move to another vault, and ask whether it goes with the host
Keys sync and keys are shared: SshKey is in the sync registry on both sides, the
material rides in the sealed payload, and every generation of the vault key is
wrapped to a new member. What was missing was the way in. Hosts and groups could
move between vaults and keychain items could not, so a key typed into a personal
vault before the team existed stayed there for good — and moving a host into the
team's vault left it authenticating with something nobody else in that vault can
read. The code said so and could do nothing about it: "the answer is usually to
put a copy of that key in the destination vault", which meant pasting the private
half into a second item and deleting the first. A private key on a clipboard, and
two items nobody can tell apart afterwards.

MoveAsync already existed on the generic repository and is now exposed for keys
and passwords as it is for hosts and groups. What had to be built around it is the
re-aim. An item re-sealed under another vault's key lands with an id of that
vault's making, so every host bound to the old one and every group lending it as a
default is left naming a tombstone — and a host bound to something its vault no
longer holds refuses to connect rather than falling back to a typed password. A
move without the re-aim would look like a success and break every machine on that
key. It runs over every vault this session can write to, because a binding
resolves across all of them, and it counts what it could not rewrite: an item from
a newer client, or one in a vault this account may only read. Those are said in
the sentence afterwards rather than swallowed.

The host's move asks the question rather than deciding it. A binding resolves
across vaults, so the moved host goes on working for the person who moved it
whichever way this is answered; it is the colleagues they have just joined who
hold one vault's key and cannot connect with a host whose key stayed behind.
Unticked, and it stays that way on purpose: moving a key into a team's vault hands
it to everybody holding that key, and this design does not default anybody into a
disclosure. Under the box is the count of everything else that authenticates with
that key, because a key twenty machines use is a different decision from one
nothing else touches, and neither number is visible from the panel otherwise. The
question is answered against the vault in the picker, so choosing a different
destination re-asks it and a key already in the destination offers nothing.

One thing fixed on the way. A host that inherited its key from its group arrived
in the destination naming nothing at all — the group belongs to the vault it left
— so a machine that connected before the move refused after it, with no sentence
anywhere saying why. The resolved binding is now written onto the host as it
crosses, and the stranded-binding warning reads the resolved binding too, which is
the case where somebody is least likely to know a key is involved.

MOVE is on both heads, for keys and passwords only: a tag, a bucket and a pin are
read from the active vault alone, so "another vault" is not a question any of them
has. Four tests cover the move and its re-aim, the host's move with the key
brought and without it, and the inherited binding.

jaap-jan 3d9ed03b09 Let a snippet be shared to a vault, the way a host already can
A snippet was a first-class vault item everywhere except where it mattered: the
crypto, the sync, the server table and every registry already treated it exactly
as they treat a host, and the screen read it out of the active vault alone. So
the one command a team most obviously wants to hold in common — the incantation
somebody worked out once and everybody else retypes — was the only item kind that
could not leave the machine that wrote it.

The read is the half that had to come first, and it is why this is not simply a
MoveAsync. ReloadSnippetsAsync now lists every readable vault rather than the
active one, in the shape ReloadHostsAsync and ReloadKeysAsync already use: the
vault new items go into first, then by vault name, then by label, with a badge on
the row only where there is more than one vault to tell apart. Without that, a
snippet moved into a team vault would have disappeared from the very screen that
moved it, and one a colleague wrote there would never have arrived at all —
sharing would have looked like losing.

Three writes were pinned to the active vault and each one broke differently once
the list spanned several. The delete tombstoned in the wrong vault, which
tombstones nothing and leaves the snippet on screen. The save is the bad one: an
update sent to the active vault creates a second snippet there and leaves the
team original untouched, so the person editing sees their fix and nobody else
ever does. That is a fork with no symptom, which is why the vault is now a
parameter and the screen latches it when the editor opens — the chosen vault for
a new snippet, the row own vault for an existing one — rather than reading it
back off a selection that can move under a half-typed form. VaultViewModel has
carried editingHostVaultId for the same reason since hosts crossed vaults.

Two controls rather than one, and that is the same line the host pane draws. The
editor asks which vault a new snippet is filed into; MOVE re-seals an existing one
under another key and tombstones the first. Putting the second inside the first
would let somebody correcting a typo hand a command to a team by leaving a picker
where they found it, so the picker is not drawn for an existing snippet at all.
Both live on SnippetsViewModel rather than VaultViewModel because this screen owns
its editor, unlike the host drawer; the writing they ask for is still the vault.

A snippet crosses whole, which is the one way this is simpler than the host it
copies. A host leaves its group and its tags behind because both are items of the
vault it came from and would dangle for everybody in the destination. A snippet is
a label, a command and a note, and none of them points at anything — so there is
nothing to strip, nothing to report as left behind, and what the copy says instead
is the thing that is actually at stake: who can read the command afterwards. For a
command that may carry a hostname or a path, that is the whole decision.

Two judgement calls worth finding later. A hidden vault now hides its snippets,
filtered in the screen projection rather than in VaultViewModel.Snippets, which is
the rule keys and passwords already follow: the list stays whole so nothing that
resolves against it breaks, and the projection is what a preference about reading
gets to change. And the nav rail count is left spanning vaults unfiltered, because
Vault.Hosts.Count beside it is unfiltered too — filtering one of the four would
make the rail disagree with itself.

Four flow tests in VaultSharingTests, beside the host ones they mirror: the move
re-seals with a new id and carries the runs-on-insert flag across, the move with
nowhere to go refuses rather than opening an empty picker, the editor files into
the vault chosen on it, and the edit of a shared snippet goes back to its own
vault instead of forking. That last one is the regression the latch exists for and
the only one whose absence has no visible symptom. Plus a layout test with the
move panel open, since that paragraph wraps in a 300-pixel column and the desktop
pane it lands in is measured.

The whole suite passes: 1660 tests, none failing.

jaap-jan af0e29a98b Give the desktop a nightly channel, the way the phone has one
ADR 0014 gave the phone a nightly and ADR 0013 rule 3 gave the desktop none, so
the two heads had different answers to the same question — how does somebody try
what is on main? — for no reason except the order the work happened in. This is
the desktop's answer: CI publishes a build from main on every push, and it
installs beside the release one rather than over it.

The phone gets its separation from the platform. Android refuses an update signed
by a different key, so its two channels cannot replace one another whatever
anybody does. Nothing refuses anything here: Velopack applies what its feed serves
and verifies no signature. So all of it is construction, and there are four
separations because each closes a different door.

A pack id each, so the two install in different directories and neither feed's
package can be applied to the other's install. A Velopack channel each —
win and win-nightly — so neither build ever reads the other's release index; the
name reaches the wire as releases.win-nightly.json, which is why the constant in
VelopackUpdateChannel and the argument in ci.yml have to agree or the channel
answers nothing forever with no error. A prerelease flag, so the release channel
cannot see the nightly even by accident. And a profile directory each, which is
the one that is easy to skip and would hurt most: the cache schema is migrated on
every launch, before unlock, so a shared profile means a nightly quietly upgrading
a database the release build then opens. Both are installed at once by design, so
that is an ordinary Tuesday rather than a corner case.

The prerelease flag turns out to be load-bearing across heads as well. The phone's
release channel reads releases/latest, which skips prereleases — so a desktop
nightly published as a stable release would become the newest release in this
repository and every phone on the release channel would start failing its check
against a release carrying no Android manifest.

Which build this is arrives as assembly metadata, the same mechanism and the same
reasoning as the Android head: the updater needs the string rather than a branch,
and a value baked into the assembly is one a crash report can be asked for. Three
things read it — the feed, the prerelease flag, and the profile — and one more
shows it: the titlebar says DodoSSH Nightly. Everything else that distinguishes
the two is somewhere nobody is looking while typing a passphrase into one of them.

The version needed a floor and it is applied to the whole build rather than to the
packaging. MinVer answers 0.0.0-alpha.0.N until the first v* tag and vpk refuses
anything below 0.0.1, so the job lifts the patch digit and keeps the height —
through MinVerVersionOverride, so the assemblies carry the same number the
installer does. Packing a version the assembly disagreed with would put one string
on the preferences screen and another in the feed, which is the screen somebody
reads when asked which nightly they are on.

Two things found by running it rather than reading it. -t:MinVer needs a restore
first, because the target arrives with the package and MSB4057 on a clean checkout
reads like a typo in the workflow rather than a missing restore; the release
script had the same gap and now restores before it reads. And vpk rejects an empty
--packVersion loudly, which is how a broken version handoff announces itself
rather than shipping a package called 1.0.0.

Rule 3 is untouched. The release channel still has no job, no token and no runner,
and the two channels cannot see each other. What a nightly costs is written where
somebody reads it before installing one: whoever can write a release here can put
a build on every nightly machine, which is fine for a build being tried and is not
fine for a build holding somebody's infrastructure credentials.

Verified by running the job's own steps against a clone in a Linux container:
DodoSSH.Desktop.Nightly-win-nightly-Setup.exe, and an index naming pack id
DodoSSH.Desktop.Nightly at 0.0.1-alpha.0.144. The upload itself is the one step
not exercised — it needs a real forge and a write token, and check 16.10 is what
walks the half no runner can.

jaap-jan dc1ebf6afa Let the recovery code be copied, and give the phone a clipboard to copy to
ci / build and test (push) Canceled after 0s
ci / android head (push) Canceled after 0s
ci / api image (push) Canceled after 0s
Both screens had made the code selectable and both said why: a person who cannot
get it out of the box photographs the screen, and a screenshot is a worse home
for it than a clipboard. This finishes that argument. Selecting 64 characters of
letter-spaced monospace with a thumb is the version of "possible" people give up
on halfway — and on the phone the screen blocks screenshots, so the honest
remaining options were retyping it or losing it.

It is the one secret this application deliberately offers to a clipboard, and the
contrast with the keychain's copy is the whole argument rather than an
inconsistency. There, copying the private half is refused outright, because
installing a key means pasting the public one and the private one has no business
leaving the vault. Here there is no better route: the code exists for one screen,
is stored nowhere, and has to reach a password manager. The clipboard is the
intended destination rather than a way round the design.

The sentence afterwards matters as much as the copy, and is asserted: a clipboard
is a staging post, this screen is the only place the code exists, and the next
thing copied replaces it. Somebody who copies and does nothing has not saved it.

The phone had no clipboard delegate at all — the desktop passed one and this head
passed null — so COPY PUBLIC KEY on the keychain answered "this machine has no
clipboard" on a device that plainly has one. Nothing about that was platform
shaped: Android has a clipboard and Avalonia surfaces it through the same
TopLevel. Wiring it fixes that copy too.

The test fixture built its shell without a clipboard, which modelled the bug
rather than the product, so it has one now and the public-key test asserts what
lands there instead of the refusal. The refusal keeps its own test, on a shell
built without one, because the view model reads the delegate's absence rather
than an empty result — and because a button that silently does nothing on this
screen is worse than one that refuses.

jaap-jan ca07d63585 Offer to bring the keys an ssh_config points at
ci / build and test (push) Successful in 2m0s
ci / android head (push) Successful in 6m5s
ci / api image (push) Successful in 42s
An import that recorded a key path and left every host asking for a password was
an import whose result did not connect. The answer to that was a manual paste per
key, which is the sort of thing people do once and then stop importing.

So there is a tick, and it starts off. With it off nothing changes: an
IdentityFile becomes a note and the host asks for a password. With it on, IMPORT
reads each host's first IdentityFile out of ~/.ssh, stores it in the vault
encrypted like any other key, and binds the host to it.

Three things about how it is drawn are load-bearing rather than tidy. It is a
default nobody arrives at by accident. The sentence beside it names the directory
rather than saying "your keys", because that is what somebody is agreeing to. And
nothing is read during SCAN — tick it, read what it says, untick it, and no
private key has been opened. This is the only place the application opens key
material out of a directory the user did not point at file by file, and the whole
of what makes that acceptable is that it took a deliberate press.

One vault key per file, however many entries named it: an ssh_config pointing
twelve hosts at one id_ed25519 is the ordinary shape, and twelve copies would be
twelve things to rotate and eleven to forget. A file whose material is already in
the keychain is bound to rather than stored again, which is what makes running
the import twice harmless.

What cannot be read off a disk is a passphrase, so a protected key arrives
without one — and the report under the button names those files rather than
leaving a host to fail at connect time with a message about a malformed key.
Telling them apart means decoding for OpenSSH's own container, whose cipher name
is the first field inside the base64 rather than anything in the armour, and that
is the format ssh-keygen has written by default for years. The 88 base64
characters it decodes need 66 bytes, not 64: with the smaller span every
protected key came back unprotected, which the tests now pin.

A path that is not on this machine leaves its host imported and unbound, exactly
as it would have been with the tick off, and is named in the same report. A
config carried from another machine is the ordinary case, not an error.

jaap-jan 69bc9e270b Let a team be joined only by somebody who is already here
An invitation decided access from an assertion about an address. Everything else
in this model decides it from something a person did — an admin naming an
account, a key holder wrapping a vault key to a key they verified — and this was
the one place a token's email claim was the thing that let somebody in.

It was guarded as tightly as that can be guarded: the claim was refused outright
on an unverified or absent `email_verified`, with no setting to relax it. But the
guard and the risk were the same shape. The whole defence was one boolean sent by
a system the deployment does not control.

So `POST /teams/{id}/members` is the only way in, and an address with no account
is refused with `no-such-account` — which is now the end of the road rather than
the signal to invite. Both clients say the remedy: that person signs in here
once, which is what creates the account, and then they can be added. The desktop
leaves the address in the box, because a message telling you to come back later
is one you act on later.

Gone with it: the `team_invitation` table, the claim hook in the sign-in path,
and `Oidc:EmailVerifiedClaim`, which that hook was the only reader of. Nothing in
the server now reads the email claim to decide anything.

Pending invitations are dropped rather than converted. Converting one would mean
creating a membership because an address matched, which is the property being
removed — and an invitation to an address that did have an account here had
already been claimed by the hourly sweep, so what is left is offers to people who
never arrived.

Two tests carry the property rather than the feature: the endpoint inventory
asserts the three routes are absent, and the API suite adds an address that has
no account, watches the refusal, then signs that address in and checks it joined
nothing. Without the second half, a server that merely renamed the deferred path
would pass.
2026-08-05 08:28:57 +02:00
jaap-jan 3ead865f01 Merge branch 'main' into the desktop updater, and give way on two numbers
Main landed a realtime push feature while this branch was building the updater,
and the two collided in three places. Every one of them resolves the same way:
main got there first, so this branch moves.

**Two ADRs were both numbered 0012.** Main's is realtime push; this one is now
[ADR 0013](docs/adr/0013-desktop-distribution-and-updates.md). Git did not call
this a conflict — the filenames differ — so it would have merged quietly and left
the directory with two 0012s and every cross-reference ambiguous. Renumbered here
along with the nine places that point at it.

**Two manual-check phases were both numbered 15**, and that one git did catch.
Main's "Changes that arrive without a timer" keeps 15; installing and updating
the desktop client becomes Phase 16, with its checks and every reference to them
renumbered. The file's own rule is that a number is for life, which is exactly
why the one that had not been pushed is the one that gives way.

**The merge rewrote several files with CRLF**, and `.editorconfig` asks for LF on
everything except `*.ps1`. That is not cosmetic here: IDE0055 is an error and
`EnforceCodeStyleInBuild` is on, so it failed the build on three lines of
App.axaml.cs whose only change in this branch was an ADR number in a comment.
Forty-six files normalised back to LF; the release script keeps CRLF, which is
what `.gitattributes` and `.editorconfig` both already say for a PowerShell file.

Nothing else conflicted. The updater does not touch the sync loop or the event
stream, and the one file both sides edited heavily — MainWindowViewModel — merged
without a hunk in common.

Verified after merging: the solution restores locked and builds clean, and 304
shell, 100 layout, 54 session, 28 client-api and 25 contracts tests pass. The
first two counts are higher than before the merge because main's own tests came
with it and pass alongside these.
2026-08-04 17:52:57 +02:00
jaap-jan 780f4bf892 Merge branch 'main' into the group's move and its deletion question
Main took the group's EDIT and DELETE off the GROUPS heading while this branch
was adding a MOVE beside them, so the conflict was about the same six pixels
from both directions. Main's answer wins outright, and it is the better one for
the reason its own message gives: a button beside a heading has no card under a
pointer to mean, and had to work its subject out from the selection or from the
trail. Moving a group had that problem worst of all — the thing it takes with it
is everything on the shelf, and "which shelf" is not a question a button there
could answer plainly.

So the MOVE button is gone and the menu entry it was drawn beside is the whole
of it. That entry was already in this branch, above the separator DELETE sits
below, and it needed no change: the card menu selects whatever was right-clicked
before it runs anything, which is exactly the aiming a group move wants.

Three things went with the button. ShowsGroupActions, which main deleted because
hiding buttons was all it did, and which this branch had extended to hide them
for the move panel as well. CanMoveGroupTarget, which existed to answer whether
that button was worth drawing — CanMoveSelectedHost stays, because the phone
really does leave the host's MOVE out rather than offer a refusal, and a menu
whose entries came and went would be a menu whose items move. And the two test
assertions that read them, which were describing the button rather than the
behaviour; what they were guarding is that the two panels never share the
moment, and IsConfirmingGroupDeletion says that directly.

The move panel and the deletion question both keep their place under the
heading, which is where the buttons were and is now simply where that section
puts things. They still exclude each other, by disarming rather than by a
visibility flag: MoveGroup clears a pending deletion and DeleteGroup folds the
move panel away.

Manual checks 3.3 was rewritten by main for the menu and by this branch for the
tick, and now says both; 3.3a is new and walks a two-level shelf across a vault
boundary, which is the half of this feature no headless test can watch land.
2026-08-04 17:11:06 +02:00
jaap-jan 6728a0a597 Let the desktop client replace itself, and give the repository one version
Packaging for Windows, and the updater that only exists once something is
packaged. Velopack, win-x64, fed from the project's own forge — never from the
deployment a client signs in to, which is ADR 0011 rule 2 carried over
unchanged and is why the feed address is a constant in the code rather than a
setting. See docs/adr/0012-desktop-distribution-and-updates.md.

**Nothing is ever installed while somebody is using it.** A newer build is found
on a six-hourly pass, downloaded in the background, and then waits — for a
restart the user presses, or for the next launch they were going to do anyway.
That is a policy rather than caution: this application argues at length that
locking keeps shells running, because a lock that destroyed work would stop
being used, and a restart does not keep them. Having taught that, it owes the
user the choice at the one moment it stops being true, and the sentence saying
so counts the shells it would close.

**The version is now derived from the v* tag**, by MinVer, for everything. There
was no version before this — no property anywhere, so every assembly reported
the SDK's 1.0.0 and the API served that string as its serverVersion to every
client that asked. The tag was already the version of record for the container
image; this makes it the version of record full stop. MinVer's failure mode is
answering plausibly rather than failing, and here a wrong version is a client
that never updates, so it is guarded twice: fetch-depth 0 on every checkout, and
a step that fails a tag build when the tag and the computed version disagree.

**The pack id is DodoSSH.Desktop and not DodoSSH**, which is the one decision
here that would have destroyed data. Velopack installs to %LOCALAPPDATA%\<packId>
and removes that whole directory on uninstall, and %LOCALAPPDATA%\DodoSSH is
where ClientPaths keeps the encrypted cache, the outbox of changes not yet
pushed, and the device key. The obvious id would have had the uninstaller
silently delete work the server has never seen — the thing the application
refuses to do without a counted confirmation. Velopack's own advice to move user
data to roaming %APPDATA% is declined for the reason ClientPaths already gives.

**Releases are cut by a person, and CI gains no job that could.** The tempting
argument is that a forge write token is not a signing key. It does not survive
contact with what the token does: Velopack clients trust their feed and do not
verify a package signature when they apply one, so whoever can write a release
can ship an update every install runs. That is the capability ADR 0011 rule 1
puts on a machine which is not a runner, reached through a different door. The
mechanical objection — vpk needs Windows and the runners are Linux — is the
smaller of the two and is recorded beside it, because somebody will fix one and
believe they are done.

Unsigned for now, deliberately and with the cost stated where a user reads it:
SmartScreen warns once per person, on Setup.exe, because Mark-of-the-Web is
applied by the browser that downloaded it. In-app updates are fetched by the
application and applied from a local file, and never trip it.

The banner is a fourth row of the window rather than an overlay. Anything drawn
in the terminal's rectangle is sliced by the native child window that composites
above it — the defect this window has shipped once — and a sibling row is the
arrangement TitleBar and StatusBar already prove works.

----

Three defects surfaced on the way, none of them in the feature being built.

**A settings key absent from the file came back as the CLR default, not the
declared one.** The JSON source generator builds a record through a synthesised
parameterised constructor and assigns every property from its argument array, so
a property initializer runs and is then overwritten by a default for anything the
file did not contain. A settings.json of {} read back a font size of 0, clamped
up to the 8px floor rather than the 13px the renderer draws at. It could not bite
while there was one setting, because that setting was written on every save and
so was never absent; adding a second would have turned automatic update checks
off for every existing profile, silently, the opposite of the documented default.
Reflection-based deserialisation of the same JSON answers correctly, which is why
every way of checking it by hand agrees except the one that ships. The defaults
now live on the constructor parameters, which is the only place the generator
reads them from.

**Declaring a RuntimeIdentifier on the desktop head broke the server's image
build.** It is the obvious way to let a self-contained publish restore under
locked mode, and it writes a net10.0/win-x64 target into the lock file of every
project the head references transitively — including DodoSSH.Contracts and
DodoSSH.Crypto, which the API builds too. The Dockerfile restores those with no
RID and fails NU1004. Found by running docker build rather than by reading. The
RID stays out of the committed state; the two commands that need one ask for it
unlocked, and the release script puts the lock files back.

**A Docker ARG named VERSION silently sets MSBuild's Version.** An ARG is an
environment variable for the rest of the stage, MSBuild reads environment
variables as properties, and property names are case-insensitive. With the
workflow passing main-<short sha> on a main build the publish died with
NETSDK1018 pointing at DodoSSH.Contracts, a project nobody had touched. The build
stage's argument is ASSEMBLY_VERSION now, empty except on a tag build.

All three are in docs/platform-flags.md, which is where the next person will look.

----

Verified: the whole solution builds and restores locked; 289 shell, 93 layout and
54 session tests pass, including the regression test for the settings defect and
a measurement of the banner at the window's minimum width. vpk pack runs end to
end and reports "Verified VelopackApp.Run()" against Program.Main. The API image
builds correctly both as a main build and as a tag build, carrying 1.0.0 and
0.1.0 respectively.

Not verified, and it needs a published release to be: installing, updating and
uninstalling on a real machine. That is Phase 15 of docs/manual-checks.md, and
the pack id and the WebView2 profile fix are reasoned and commented but only
proved by walking it. Two things to watch at the first upload — the reverse
proxy's body-size limit for a 64 MB asset, and whether vpk upload gitea is happy
with Gitea 1.27.1.

jaap-jan a86731ee08 Move the shelf as well as what is on it, and ask what a deletion takes
Two things about a group, and they turn out to be the same argument twice.

**A group can be moved to another vault, and it takes everything on it.** The
host's move shipped last week and stopped one level too low: moving twenty
machines into a shared vault meant twenty trips through a menu, and each one
arrived stripped of the group it had been filed under, so the shelf had to be
rebuilt by hand on the other side. Moving the shelf is what people were
attempting. MOVE sits between EDIT and DELETE over the group cards, and on the
card's own menu above the separator DELETE is below — the same place, and the
same reasoning, as the host pane's ⋯ entry.

**The whole subtree goes, and taking less was never coherent.** A group's
children are items of the vault it is leaving, so a parent moved alone leaves
them naming a tombstone and they surface as roots in the vault the user has just
emptied: half a shelf here and half there, from one gesture that said "move
this". The hosts are the same argument and are the half the request was about.

The groups go first, top down, and the hosts last. Each item is re-sealed under
the destination's key and takes a new id — VaultItemRepository.MoveAsync, which
HostGroupRepository now exposes — so nothing pointing at a group can be written
until that group has landed and its new id is known, and a child's parent must
already be over there. What an interruption leaves is therefore hosts still in
the vault they started in, under UNGROUPED: visible, and re-movable. The reverse
order would leave hosts in the destination filed under nothing.

The parent stays behind and the tags are dropped, which is the host move's rule
one level up: both are items of the vault being left, so a reference carried
across would resolve on the machine that moved it and dangle for everybody else
in the destination. The moved group arrives at the top level, and the panel says
so before the press rather than the status line saying it after. Keys and
passwords are kept — those genuinely resolve across vaults, and clearing them
would take a working host and make one that cannot connect — and any now outside
the destination is named, because that is precisely what the other members of it
will not be able to resolve.

Refused as a whole where anything under the group was written by a newer client,
rather than skipped item by item: a move that left behind what it could not
re-encode would file some of the shelf in one vault and the rest in the other,
which is the state this exists to prevent. Refused with a host editor open, as
the drop gesture is, because it rewrites hosts. And the walk carries a visited
set, for the reason every walk over this tree does: a group that is its own
parent — which two offline clients can build and no editor was ever shown —
would otherwise be appended to the move list for as long as there was memory.

**Deleting a group now asks what should become of the hosts under it, and that
reverses a decision this repository had written down.** The deletion did not
touch them: the reference was left dangling, the list resolved it to nothing,
and the machines turned up under UNGROUPED. That was right for one of the two
things people delete a group for and wrong for the other — a heading being tidied
away should leave its machines alone, and a project that has been decommissioned
is a shelf and everything on it — and nothing in the code can tell which of the
two it is looking at. So it is asked.

A tick rather than a pair of options, because the two answers are not equally
weighted: keeping the hosts is recoverable and deleting them is not, so the safe
answer is the one that needs no decision. It is off on every question, including
the one that disarms it, or a tick left standing would destroy the next group's
machines on the strength of a decision about the last one's.

Once the deletion knows which hosts it means, leaving them naming something that
has gone is a state kept for no reason, so the unticked answer writes too: N
hosts with the reference cleared, where the ticked one writes N tombstones. That
is the N writes HostGroupRepository refuses to hide behind a DeleteAsync
overload, made where somebody asked for them and where the count is on screen
first. The nested groups take the deleted group's place in the tree rather than
being orphaned to the top level. A read-only host is skipped, counted and named,
because unfiling it would re-encode a payload this build cannot represent — and
the cost of skipping is a dangling id, which every reader here already survives.

**Both are the desktop's alone**, and that is not an omission. The phone draws
groups as headings in the host list and has never had a way to delete or move
one; the two panels take the row of buttons over the group cards, and there is
no such row on a 360dp screen to take.

One test had to change its premise rather than its assertion.
EditingAHostWhoseGroupIsGone built its dangling reference by deleting the group,
which now unfiles instead — so it imports a host naming an id nothing resolves,
which is what a group deleted on another machine actually looks like and is the
only way that state still arises. The picker's placeholder is still needed and
still covered.

Four places said an item could not be moved between vaults. Two were about a
group and were true when written; the other two were left stale by the host's
move. All four now say what is true, including the design gaps document, where
the chevron beside the vault name stays undrawn for the reason it already had.

jaap-jan d02d103569 Take the group's EDIT and DELETE off the heading row
A pair of buttons sat at the end of the GROUPS heading, and the card's own
right-click menu arrived later offering the same two things. Two controls for one
job, and the buttons were the harder of the two to read: a button beside a
heading has no card under a pointer to mean, so it had to work its subject out —
the selected card, or failing that the group the trail ends with, which once a
group is open is not a card on screen at all. The menu never has that problem,
because opening it is what aims it.

The menu is the whole of Edit and Delete on the desktop now. ShowsGroupActions
went with the buttons, since hiding them was all it did. GroupTarget stays: the
menu's two entries read it after the code-behind has selected whatever was
right-clicked, and its fallback to the open group is what makes + NEW HOST open
on the group somebody is standing in rather than on none.

One case changes shape. Opening a group with nothing inside it folds the card
grid away, so from in there nothing can be right-clicked — renaming that group
means pressing the trail back one level, to where it has a card of its own. The
buttons used to cover it through the fallback. The trail was already the way out
of an empty group, and 3.2a says so now.

The test that pressed EDIT through its binding is replaced by one holding that
no button on the screen commands either of them, which is the failure worth
catching: a button coming back is not a compile error, and it would draw itself
in place, aimed at the group the trail ends with. What that test covered — a
command that has to accept an empty parameter, and act on the card the pointer
was on — the two menu tests beside it already do.

jaap-jan 3f419cb19b Let one card be selected at a time
The hosts screen draws two grids, one above the other, and each is a ListBox
with a selection of its own. Nothing joined them, so a group card and a host card
could be lit at the same moment — two chosen things, under two pairs of buttons
of which only one would act on whichever the eye had settled on. Both grids mark
a selection the same way, so there was nothing on screen to say which of the two
the next press belonged to.

They share one mark now. Selecting a host clears the group and selecting a group
clears the host, and that second one takes the detail pane down with it: a pane
about one machine cannot go on standing beside a marked group, because nothing
on it would be about what is selected.

Losing a selection deliberately clears nothing. A null arrives whenever either
list is rebuilt — every keystroke in the filter box and every background sync —
and treating that as somebody deselecting would take the mark off a group card
because a search emptied the grid beneath it.

The reload needed the same guard for the same reason. It falls back to the first
host when nothing is selected, which is what puts a target under CONNECT on a
fresh unlock; with one mark between the two grids that fallback would have
unselected a group nobody had touched, once a minute. It is skipped while a group
holds the selection, and it moved into a method of its own because the comment
saying why pushed ReloadHostsAsync past sixty lines.

One consequence needed handling rather than accepting. The phone's only route
into the group editor is a button on a heading in the host list, and it worked by
selecting the group first — which under this rule takes the highlight off the
machine somebody was about to connect to, on a screen that draws no group cards
to say where it has gone. EditGroup takes the group as an argument now: the
heading passes its own row, and the desktop's button beside the cards passes
nothing and still means "the card that is selected".

What the tests hold is the half that lives in the controls. Clearing the property
has to reach the list that is drawing the card, and a selection nulled in the
view model while the card stays highlighted is the exact failure this is about —
so the rule is driven on the real screen, in both directions, against the
ListBoxes' own SelectedItem. The desktop's EDIT is pressed through its binding
for the same kind of reason: a command refusing the button's empty parameter
would be a button that never fires, and nothing about the markup would say so.

jaap-jan c39df3f51e Share the shelf as well as what is on it, and ask a group which vault
A group is where hosts are filed and what lends them a port, a username and a key,
and until now it could only ever be made in the vault this machine files new items
into. So sharing a vault shared the machines and not the arrangement: a colleague
opened four hosts filed under a group they could read the name of and nothing else,
and the group a teammate made had no card, no heading and no way to be corrected
from the screen looking straight at the hosts inside it. Recorded as half shipped in
docs/design-import-gaps.md, and this is the other half.

The list stopped being the active vault's. It was narrow for two stated reasons —
a row shown across vaults has to carry which vault it lives in, because rename and
delete both need it, and two vaults may hold a "production" each, which a layout
with one heading per group cannot tell apart — and both are now paid for rather than
avoided. Every row carries its vault, the badge beside the name says which, and the
two cards sit side by side saying what they are.

The three shapes of the group read are now deliberately different sizes. The list is
what a person looks at, so a hidden vault's groups leave it: a card that cannot be
opened onto anything is worse than no card. The per-vault lists are what a picker
offers, because a picker is always asking about one vault. The map is what a host's
GroupId resolves through, and it stays widest of all — including over hidden vaults,
since a group lends a port and hiding a vault must never change what one of its
hosts dials. RebuildGroups is the one place hiding is applied, which is what keeps
those answers apart.

The editor asks which vault on the terms the host editor's picker set: while adding
only, hidden where there is one writable vault, and never offered afterwards, because
the two are encrypted under different keys and moving an item is a delete and a
retype. Its parent picker is that vault's alone, for the reason the host editor's
group picker is one level down — a parent in another vault is a level half the key
holders cannot resolve, and their hosts would inherit from nothing. + NEW GROUP
inside an open group departs from NewHost and takes that group's vault rather than
the standing preference: a group made inside another is in its parent's vault by
construction, and answering "inside PLATFORM" with a group elsewhere and no parent
would drop the one thing the button said.

Two smaller things follow from the cards spanning vaults. Dragging a host onto a
group card in another vault is refused with both names, because the write it would
make is exactly the id-nobody-can-resolve the host editor's picker was fixed to
prevent, and treating it as "no group" would unfile a host somebody was plainly
filing. And a group being renamed says its vault in the drawer's header, since the
picker is not drawn for an existing one and renaming a colleague's shelf without
being told whose it is is the edit most worth naming.

The save target is a nullable field behind a property that falls back to the standing
preference. The group name box is bound whether or not anything raised an editor over
it — that is what the desktop's group bar was, and typing a name into it and pressing
ADD is still a way to make a group, which would otherwise have written to no vault
at all.

1575 tests pass, five more than before: a group filed into a shared vault is listed
and renamed there, the editor's picker does not move the keychain screen's, the
parent picker offers only its own vault, a cross-vault drop is refused, and hiding a
vault takes the cards without changing what its hosts dial.

jaap-jan be012585b3 Let a group be right-clicked, as a host already can
The host cards have had a menu since the grid replaced the sidebar; the group
cards above them had a double-click and two buttons beside the heading, and
nothing that named the card under the pointer. Open, Edit and Delete are on them
now, drawn and aimed the same way.

On the list rather than in the item template, for the reason the host grid's is:
the three commands are the vault's, and a ContextMenu inside a DataTemplate has
the row for its data context, so every binding in it would silently resolve to
nothing. The code-behind selects whatever was right-clicked before the menu
opens, and that is what makes one menu act on the card under the pointer rather
than on whichever was selected before.

**Cancelled over the space around the cards, and here that guard is doing more
than the host grid's.** GroupTarget falls back to the group whose contents are on
screen when no card is selected — the right answer for a pair of buttons beside
the heading, which would otherwise have no subject the moment a group with
nothing inside it is opened, and the wrong one for a menu that opened on a card.
Without the guard, right-clicking the gap beside the cards would offer to delete
the group the trail ends with: a question about something the user is not
pointing at, in the one menu where the answer is a deletion.

Only Open takes a parameter, and it has to. OpenGroupCommand's null is a real
argument rather than a missing one — it is the trail's first crumb, ALL HOSTS —
so an entry with no parameter would not open the card, it would leave the group
the user right-clicked and go back to the top level.

Two tests beside the two the host menu already had. What they hold that a build
cannot is the CommandParameter binding: a path that resolves to nothing compiles
and draws, and the entry would then quietly do the opposite of what it says. The
popup itself is still the platform's, so manual-checks 7.9 gained the group half
of the same check.

jaap-jan bee6202949 Let a host be moved to another vault
The one thing the host editor's vault picker has always been unable to offer,
and the comment beside it said so: an existing host's vault was not a field
because the two vaults are encrypted under different keys. That is still true.
What changed is that it is no longer a reason to have nothing.

**A move is a copy and a tombstone, and it cannot be anything else.** A payload
is sealed under its vault's key and its AAD binds the vault, the entity id and
the item version, so no edit moves one and no server call could — the server
holds ciphertext it cannot read. What crosses is the plaintext, in this process,
between an unwrap under one key and a seal under another. VaultItemRepository
gained MoveAsync for it, so the three decisions below live in one place with
their reasons rather than being re-derived at each call site.

The item takes a new id. Keeping it would put one entity id in two vaults, and
the item table is keyed on the type and the id rather than on the vault — so the
destination's row and the source's tombstone would be the same row, and the move
would delete what it had just written.

The write comes first and the tombstone second, which decides what an
interruption leaves: a copy in both vaults, visible and deletable, rather than a
tombstone with nothing on the other side. Both are queued rather than sent, so
the window is a crash between two local writes; it is still worth being on the
survivable side of.

Two activity lines rather than one, because that is what the two vaults actually
record. A single "moved" line would have to be written to one of them and would
be missing from the other's history.

**The group and the tags stay behind, and that is the half that makes this
honest.** Both are items of the vault the host is leaving: the editor's group
picker offers one vault's groups and the chips are drawn from one vault's tags.
A host carrying either across would resolve it on the machine that moved it —
groups and tags are resolved over every readable vault — and dangle for everybody
else in the destination. The mover and their colleagues would be looking at two
different hosts. Cleared and reported beats carried and invisible.

The key or password binding is kept, and the difference is not inconsistency.
Those genuinely resolve across vaults — one key on twenty hosts in three vaults
is the arrangement they exist for — so clearing them would take a working host
and make one that cannot connect. What the message does instead is name a
binding that is now outside the destination, because that is precisely what the
other members of it will not be able to resolve.

**It is not in the editor**, on either head: the desktop puts it in the detail
pane's ⋯ menu above the separator Delete sits below, and the phone beside EDIT.
A picker inside the form would move a machine as a side effect of correcting a
port, which is the bug the editor's own vault picker was fenced off to prevent in
the first place. The panel takes the footer as the deletion question does, and
says what will be left behind before the tap rather than after it — on a phone,
where the status line afterwards is one line on a screen somebody has already
navigated away from, that is the only place it reliably gets read.

The phone hides the button where there is nowhere to go rather than offering one
that answers with a refusal; the desktop keeps its menu entry either way, because
a menu that grew and shrank would be a menu whose items move.

One thing found while writing the test and deliberately not changed. The pass
that follows every write on this screen reports what it moved and supersedes the
confirmation — for a save and a delete as much as for a move — so the move's own
sentence is what somebody sees offline. The test asserts it in that state and
says why. Making confirmations survive their own sync pass is a question about
the whole screen rather than about this.

Four places said an item could never be moved, two of them sentences on screen in
both heads. All four now say what is true, including the design gaps document,
where the chevron beside the vault name stays undrawn for a different reason: a
chevron on a subtitle implies an edit, and this is a re-seal, a new id and two
references left behind.

jaap-jan e9cea2ccbc Let a shared vault arrive, a bucket be found, and a vault be deleted
Three things a user reported, one of which was a real bug and one of which was
not the bug it looked like.

**A vault shared with somebody never reached their machine.** The grant was
correct at both ends: the sharing client verified the recipient's key against the
key log and wrapped every generation to it, the server stored it, and /me would
have returned it. Nothing asked. VaultSession.RefreshVaultsAsync — the method
whose own summary says it is "called after a share and on a periodic pass" — had
no caller anywhere in the application, so the vault list was whatever the last
browser sign-in cached. A restart did not help: an offline unlock reads that same
cache. The vault appeared only if the recipient happened to sign in through the
browser again, which is why this looked like sharing being broken rather than
like a list that was never re-read.

So every synchronisation pass now re-reads it, before it syncs. SyncOnceAsync
takes the whole server rather than its sync half for that reason, and the order
matters: a vault admitted by the refresh is one that same pass then pulls, where
the other order would show a newly shared vault as an empty one until the minute
after. The shell is told only when the set actually changed — it rebuilds the tab
strip's vault menu from the session's list, and doing that on every quiet pass
would rebuild a menu once a minute for nothing.

The test needed the fake server to be able to do something no test here had
needed before: hand this account a vault it did not make. ShareVaultWithMe wraps
a real key to the encryption key this account enrolled, so the keyring opens it
exactly as it opens a real colleague's — a helper that filled the field with
bytes would let a vault appear in the list and never prove it could be read.

**Adding an S3 bucket on the desktop works, and could not be found.** The report
was that it is not possible; driving the real XAML headlessly says otherwise —
Keychain, + BUCKET, and the editor saves. What is true is that S3 is where
somebody goes looking, and from there SELECT BUCKET opened a combo box with
nothing in it and no sentence anywhere saying that a bucket is a keychain item.
From where the user was standing that is indistinguishable from an application
with no way to add one.

The empty state now says what a bucket is and offers a button that lands on the
keychain with the editor already open — navigating to the screen and leaving
+ BUCKET to be found among five buttons would be most of the same problem. The
phone gets the sentence and no button: its keychain screen reads and deletes and
edits nothing, so there is no editor to send anybody to, and naming the machine
that has one beats an empty control that reads as a screen still loading.

The keychain screen's layout test grew the two categories it never covered.
Tags and buckets arrived after it was written, and the header strip it measures
is one that has overflowed twice before.

**A vault can now be deleted.** DELETE /api/v1/vaults/{id}, gated on Admin —
the line the rename already drew, for a stronger version of its reason, since
this takes the vault from everybody in it at once. The row is soft-deleted and
every grant to it withdrawn in one write; VaultAccessService filters on the stamp
at both ends, so from that moment the vault is absent from every member's /me and
every call naming it answers 404. Their clients notice on the pass described
above.

The team behind it is archived when it owned nothing else, which is the mirror of
renaming it: a vault made from the vaults screen gets a team named after it that
nobody was ever shown, and leaving that behind would leave a membership list no
screen has a row for. That is a second call rather than one transaction —
archiving is TeamService's, it refuses while a team owns vaults, and it can only
tell that this one no longer does once the deletion is committed. A crash between
the two leaves an empty team: invisible, archivable afterwards, harmless, and a
better failure than a vault that could not be deleted because tidying up after it
did not work.

Two refusals worth stating. The personal vault cannot be deleted at either end:
it is created by enrollment, everything filed nowhere else lives in it, and no
call would make another. And the items are kept — ciphertext behind a vault
nothing will resolve, so deleting them buys no confidentiality while destroying
what an operator undoing a mistake would need.

The client drops the key from the keyring and the row from the cache rather than
waiting for a refresh, so the list is right immediately; the items stay, as they
stay for a vault whose grant was withdrawn, because a copy is on every other
member's machine too and removing these rows would be the client pretending to a
reach it does not have. The confirmation says that out loud before it is
answered. It is the one sentence this screen must not leave implied: deletion is
no more retroactive than revocation is. See ADR 0001.

Desktop only, deliberately. The Android vaults screen offers no rename and no
hand-over either, so adding delete alone there would be the one destructive vault
operation on a screen with no other.

Three places asserted that a vault can never be deleted — TeamService's refusal
message, the TeamNotEmpty problem code, and ADR 0009 — and each now names the
route instead.
