jaap-jan ebb88c8ae4 Give the phone both pickers, and settle who signs the APK
The files screen could browse a remote and delete on it, and that was all: there
is no browsable local filesystem on Android for a second pane to show, so the
gesture the desktop is built around — choose on the left, press the arrow — has
nothing to stand on. What replaces it is the platform's own two pickers. ADD
FILES is ACTION_OPEN_DOCUMENT, so a document is pointed at wherever it lives and
goes to the directory showing; SAVE FILE is ACTION_CREATE_DOCUMENT for the
selected row.

Both stage through the application's cache, and that copy is a requirement
rather than a shortcut. android-port.md predicted a picked document would be a
third IRemoteFileStore beside SFTP and S3; it cannot be. FileTransferQueue seeks,
because an upload resumes from the byte the last attempt reached, and a
content:// URI has no path behind it, no length worth trusting, no promised seek
and no grant that survives the document being edited underneath it. Copying
first costs one class in the head and nothing at all in the shared layers, where
the alternative was every resume rule rewritten around a stream that cannot
rewind. The copy is deleted when the transfer completes, kept while it is stopped
so RESUME still has something to read, and swept at the next launch — which is
the one moment emptying that directory is provably safe, since nothing has
queued anything yet.

Coming out had a decision going in did not: when to ask where it goes. The save
picker is raised before the transfer, so the download runs into the same staging
directory and hands its bytes to a callback the head supplied, held against the
transfer id so a RETRY still lands where the person pointed. Asking afterwards
would put the picker minutes from the button that caused it and, on a phone,
usually while the application is backgrounded and Android will not show one at
all. The cost is that the picker creates its file when it is dismissed, so a
download that then fails leaves an empty one there; that is said on the screen,
in the README and in the manual checks rather than left to be discovered. A
delivery that fails keeps the staged bytes for the sweep instead of throwing away
the one copy of something just fetched over somebody's network.

The foreground service counts transfers now, which is the half of it that
matters most here: a shell survives backgrounding because somebody is looking at
it, and an upload has to survive precisely when nobody is. Queued counts as
active, so putting five files in and locking the phone moves five files. The
seam was built for this and wired to () => 0 because nothing could fill the
queue.

Alongside it, ADR 0010 answers the second question android-port.md left open,
and it had to be answered before the first release rather than at upload time: a
new Play app must use App Bundles and therefore Play App Signing, and an
installed app can only be updated by a package signed with the same key, so the
first release picks an identity for good. The project holds the key, offline and
never in CI — the workflow's package step now says so where somebody would break
it — and a DodoSSH deployment never serves the client, because a download link on
your own server hands the binary that holds the plaintext to the party the whole
threat model is about.

The README's M1 gap note was stale in both halves and is replaced by what is
actually true: credentials have an editor and a REMEMBER tick, and the device key
registers into the TPM under a CNG policy that makes the consent dialog a
condition of using it. What is left is the floor rather than a gap — no TPM, or
no Windows, means the passphrase on every launch.

jaap-jan 61139bd469 Move the SFTP and S3 connection into the right-hand pane
THE CONNECT BAR IS GONE. It was a 44-pixel strip across the top of the file
screen holding a heading, a picker, a password box and a button — chrome
spanning both panes in order to configure one of them, drawn at full width
whether or not anything was ever going to be connected. Underneath it sat a
pane that was empty for exactly the same reason, saying so in a sentence
nobody had to be told twice.

So the pane says it instead. Disconnected, the right-hand half is an invitation
where the listing would be: what the screen is for, what pressing the button
costs, and one thing to press. SELECT HOST opens the picker in place — the same
combo, the same password box, the same CONNECT — and the sentence and the
button go away with it, because by then they have been read or they have not.

Two steps rather than a picker sitting open, and that is not decoration. The
reason the pane is empty is the question, and a combo box in the middle of it
is a form with no question above it. The two steps also keep the panel inside
its budget, which is the pane's height less whatever the queue has taken — 268
pixels with three transfers on it. Neither shape reaches the floor, and the
layout suite measures both.

IsChoosingRemote is cleared by everything that changes what the picker would be
picking: connecting, disconnecting, moving between the SFTP and S3 tabs, and
losing the vault. The last two are the ones that would rot quietly — a picker
surviving a hop to the other tab offers hosts on a screen showing buckets, and
one surviving a lock offers a list that has just been emptied because its rows
carried decrypted secrets. CANCEL takes the typed password with it, which is a
secret nobody asked to keep.

WHERE THE TWO CONNECTED FACTS WENT. The address chip and DISCONNECT are a strip
of their own inside the remote pane, above the listing — not three more cells in
the header beside UP, REFRESH and DELETE. That pane is 381 pixels wide at the
window's minimum and a fourth control in that row would have pushed one of the
three off the edge; the number is written into the markup so the next thing
added to either row is measured against it rather than tried.

The status line did not fit there either. What is left after a 170-pixel address
and a DISCONNECT is about eighty pixels, which turns every sentence into its
first word and an ellipsis, so while a session is open it is in the queue's own
strip at the foot of the screen, which spans the window. The other half of the
time it is inside the invitation, beside the button that provoked it. One home
in each state rather than two homes in one and none in the other.

The header label reads HOST or BUCKET now, which is the only thing on the screen
naming the kind — the bar that printed SFTP or S3 is gone and the tab in the
strip says it either way, whether or not this screen is showing.

The opening status text was "Choose a host and connect to browse its files",
which the invitation now says in a heading, a sentence and a button. It is
"Nothing is open yet.": a state rather than an instruction. That string is
shared with the phone, where it still reads correctly under the picker card
that head shows directly.

Desktop only, and the phone is unchanged rather than merely untouched. Its
FilesScreen is one pane at a time, so the picker *is* what it shows before a
connection exists; it binds none of the new members.

Four tests. Three in the layout suite — the picker open over a full queue, which
is the tall shape and the one that has to be measured with the panes at their
least; the bucket picker, which is a row shorter because an object store has
nothing to type; and a session open with a long enough address to prove the chip
gives way before DISCONNECT does. The fourth is the picker's lifecycle in
ShellFlowTests, over all four things that put it away. 302 tests pass across the
two suites.

jaap-jan 562fb444a8 Merge main into the phone connections branch
ci / build and test (push) Canceled after 46s
ci / android head (push) Canceled after 0s
ci / api image (push) Canceled after 0s
Main had already taken this branch's first two commits, so what merged is the
Connections work against three things that landed beside it. Four of the six
conflicts were prose about arrangements both sides changed; two were real.

**The phone hub gained a Teams row while this branch was moving the keychain
onto it.** Both are additions to `IsMoreSurface` and both belong: teams because
the desktop reaches them from its rail and the phone through the hub, the
keychain because a bottom bar is for the places a session moves between. The
membership test, the back gesture's first case and the hub's own arithmetic all
take the union. The distinction is now written down rather than implied — teams
is the design's count plus one, and the keychain is the only rearrangement of
it: the bar lost a slot to gain that row.

**`ConnectAndAnnounceAsync` was the real one.** Main gave it
`RememberTypedPasswordAsync`, which binds the password that just worked to the
host it worked on; this branch had replaced the `HostRowViewModel` that method
needs with a four-field `ConnectionTarget`. Keeping both meant deciding what a
manual connection does with a password that succeeded, and the answer was
already written on the screen it is typed into: nothing. There is no item to
bind a credential to and none to bind it on, and that path saves nothing by
design.

So `ConnectionTarget` carries the row again — as a nullable, in place of the
host id it had, with `HostId` derived from it. Two things read it and both are
things that can only be done to a keychain item rather than to an address:
naming the log entry, and keeping the password. Null is not missing data there;
it is the whole of what makes the manual path different, and having one field
rather than two keeps "was this a keychain host" a question with one answer.

The desktop's rail lost SFTP and S3 to the tab strip on main, so the README's
"a rail with nine slots has room" was true when it was written this afternoon
and is not now. It says the room rather than the number.

Phase 11's four new device checks and main's Phase 12 on teams were the same
conflict twice — two appends to the end of one file — and both are kept.

Verified after resolving: the solution builds, the Android head builds clean,
and 837 tests pass across the seven client suites, including main's own additions
(233 shell, 79 layout, 240 domain, 118 sync, 54 session, 74 terminal, 39
storage).

jaap-jan f5ffd1983d Make Connections the place a connection is made, and put the keychain away
Four changes to the phone, and the last one needed the connect path taking
apart.

**The bottom bar is three entries.** The keychain moved onto the hub, which is
now SETTINGS with a gear rather than MORE with a hamburger. A bottom bar is for
the places a session moves between, and keys, credentials and tags are managed
occasionally and then left alone — which is the shape of everything already
behind that hub. With the keychain on it, "more" stopped being a description of
what is there. `ShellScreen.Vault` joining `IsMoreSurface` is the whole of the
change: the tab that lights, the header that stands down and the back gesture's
first case all read that one property, which is why the switch mirrors it by
construction rather than by a second list. The keychain screen grew the header
every hub screen has, because the shell's own is not above it any more and
without one there would be no back arrow and nothing saying what the list is.

The desktop keeps its Keychain rail entry. A rail with nine slots has room, so
this is the second thing the two heads arrange deliberately differently, after
the hub itself.

**Terminal became Connections**, and the word does more work than a rename
usually does — see below. The enum member stays `ShellSurface.Terminal`, for
the reason the tab was never called Vault: the surface is a terminal, and the
word a user reads is the product's.

**The + puts the software keyboard away.** It sits above a terminal somebody is
typing into, so the sheet it raises was arriving underneath a keyboard covering
the half of the screen the sheet is on — and worse, laid out into the strip
left above it, since the keyboard's inset shortens everything this head draws.
Avalonia cannot do this and it is worth knowing why: `TopLevel.InputPane`
reports the keyboard and offers nothing that closes one, because the framework's
model is that it belongs to whatever has focus — and this keyboard was raised by
the `WebView`'s own text input, by a native view Avalonia's focus manager never
owned. Clearing Avalonia's focus leaves it exactly where it is. So
`Platform/SoftKeyboard.cs` asks `InputMethodManager`, off the decor view's
window token, and every step of it is allowed to be absent.

**With nothing open, Connections is a connect screen rather than an empty
state.** A box taking `user@host` or `user@host:port`, a password, and the
machines most recently connected to underneath. The box is the only path in this
product to a machine the keychain has never heard of, which is a real case it
had no answer for: an address somebody was handed five minutes ago. A typed
password and nothing else — offering the keychain's keys would be a second
binding resolution beside `TryBuildAuthentication`, and the argument against a
second one is written there at length. Nothing typed is saved, and the screen
says so: a machine worth keeping belongs on HOSTS, where it can carry a key, a
group's defaults and a name.

The recents come out of the vault's own connection log rather than a list kept
in this process, so they survive a restart and arrive on a new phone with the
keychain. Deduplicated by address, because this is a list of places and not of
events, and capped at six so the box stays above the keyboard. Emptied when the
vault is — they are decrypted entries naming where somebody works, and a lock
that left them on screen would be a list still readable after every key that
decrypted it was zeroed. Tapping one leads to whichever of two things it is: a
keychain host goes to that host's connect bar, where its key, its password box
and its refusals already live, and an address goes back into the box, without
the password, whose absence is the point of that path rather than a gap in it.

**The connect path was shaped like `HostRowViewModel` all the way down.** The
log entry, the identification, the failure record and the retry all took a row.
They take a four-field `ConnectionTarget` now, so a connection to an address
shares the ladder of refusals, the host-key question and the tab's lifecycle
rather than growing a second copy of them. `ConnectionRecorder.Record` and
`Identify` have always taken a nullable host id, so the log could already hold a
connection with no item behind it.

One behavioural change falls out of that and it is the one to know about:
**trusting a host key now retries the attempt that raised the question** instead
of re-running whichever host is selected. That was correct while a selected host
was the only way to connect; with a manual target it would dial a different
machine, or refuse with "choose a host first" over a key the user has just
agreed to trust. The test selects a host first, so a regression cannot pass by
connecting to the wrong thing successfully.

`LogsViewModel.ReloadAsync` split so the connections half can be read alone.
Reading the keychain's activity for a screen that offers neither would double
the decryption on the list that was already the expensive one.

Twelve tests: the parse grammar as a theory over seven refusals, the dialled
request, the retry, and both branches of tapping a recent row. The recents rows
are built by hand rather than connected-and-closed — what those tests are about
is which branch a row takes, and driving it through the recorder's queue would
test the recorder, which `DodoSSH.Client.Session.Tests` already does. What needs
a device is phases 11.6 to 11.9 of `docs/manual-checks.md`.

jaap-jan 1b7df47537 Merge main into the desktop redesign branch
ci / build and test (push) Successful in 1m26s
ci / android head (push) Failing after 5s
ci / api image (push) Successful in 20s
Four conflicts. Three were two people adding to the same spot, and one was a
real collision: main gave the connect bar a REMEMBER tick in the same pass that
this branch took the connect bar off the hosts screen.

REMEMBER is now in the drawer, beside the password box it qualifies. Nothing
about the feature changed — RemembersConnectPassword, its refusal to fire until
the remote has accepted the password, and the six tests over it are main's
untouched — only where it is drawn. The move improves it slightly and it is
worth saying why rather than claiming a merge was neutral: the bar had one row
and had to fit the box, the tick, the authentication note and CONNECT along it,
which is why the tick was a bare "REMEMBER" in tracked capitals. A column has
room to put it under the box as a sentence, where it reads as a property of the
password rather than as a fourth control in a row.

MainWindowViewModel: both sides added members after ShowTerminal — the desktop's
three fixed tabs here, the phone's connect menu on main. They do not interact,
so both are kept, each under its own heading.

TeamsScreen: main added the team's own RENAME, HAND OVER and ARCHIVE, a member's
LastActive, the role a new member arrives as, and the KEY HOLDERS list. This
branch had only bumped the file's font sizes a point. Resolved by taking main's
file whole and re-running the bump over it, so the new controls join the scale
rather than sitting a point below everything around them.

README: both sides described a different head's third pass in the same
paragraph. Both kept.

Two things checked rather than assumed, because this branch moved the furniture
the merged commits sit on. The chrome heights main's terminal work touched are
the phone's, not the desktop's — 44, 42 and 24 are unchanged, so the layout
harness's budget still describes the window. And main's keychain DELETE did not
reach VaultScreen.axaml, whose header this branch rearranged, so the five
buttons that overflowed at the larger type are still five.

2415 tests pass, up from 2369 by the 46 main brought.

jaap-jan 208443b932 Move SFTP and S3 into the tab strip, and the host list into a card grid
Four asks in one pass over the desktop head, and two of them are furniture
moving rather than anything new.

THE STRIP IS THE WINDOW'S NOW, not the terminal's. Vaults, SFTP and S3 sit at
its head and cannot be closed, and open terminals follow them. SFTP and S3 left
the nav rail to get there, which is the one semantic change: they are the two
destinations you stay in while something runs, and a rail entry is for
somewhere you go and come back from. So the rail belongs to the Vaults tab and
collapses with it, which also means SFTP, S3 and a terminal each get the full
1016 rather than the 826 a page gets.

The tab is expressed as "a page, and not one of the two the strip took" rather
than as a fourth ShellSurface. Both are still ShellScreen members and have to
be — that is what they are on the phone, where they are two rows in a hub — so
a surface each would have been a second way to say a thing Screen already says.
IsTransfersShowing and IsBucketsShowing light the other two tabs unchanged.
What is new is one field: the page Vaults comes back to, because it is the one
tab with sub-navigation and therefore the one that can return to the wrong
place. That is not the hidden field ShellSurface argues against — that one
would be a second copy of "which page"; this is a tab remembering its own.

THE HOSTS SCREEN IS A GRID, and the 268-pixel sidebar is gone. That column was
choosing among forty machines and editing one of them at two-thirds width, and
it was narrow so the editor beneath it could be a column at all. Cards took the
first job at full width; a 304-pixel drawer took the second and collapses when
nothing is selected. Pressing a group card narrows the grid; SHOW ALL is the
way back. The group editor moved into the drawer as well, which finally makes
IsEditingGroup mean the same thing on both heads — it was the phone's alone,
because the desktop's editor was a bar that was always on screen.

AreHostsExpanded and ToggleHosts went with the control that used them. They
folded the whole list away under one heading, an affordance that existed
because the column was narrow. Folding a single group is a different thing and
is still here.

THE TYPE SCALE IS A POINT LARGER and the text ramp is white. The base size was
never stated anywhere — a bare TextBlock took TextElement's default of 12 — so
raising the scale meant naming it, on Window and on UserControl. The second
selector is not redundancy: the layout harness hosts a UserControl in a window
it builds itself, and without it the suite would measure every screen a point
smaller than it ships, silently. A selector on TextBlock would have been the
obvious way and is wrong, because a style setter beats an inherited value and
would collapse every deliberate step back to one number.

#E3E7F4 is a blue-tinted white on blue-black surfaces, which costs contrast
twice — once for being darker than white and once for sharing a hue with what
it is drawn on. Pure white is 18.3:1 against the canvas where that was 15.5:1.
Every step below moved with the top, so the intervals the design chose are
kept and TextDim clears 9:1 against 6.4:1. The palette is shared, so the phone
has both changes too.

TWO DEFECTS THE HARNESS STRUCTURALLY CANNOT SEE, found by rendering the screen
rather than by measuring it, and both now covered.

The tile was 232 and was first written as 248, from arithmetic that left out
the scrolling stack's own margins. Every layout test passed — the harness asks
whether a control is inside the window, never how many fit on a line — so the
grid quietly became one column wide at exactly the minimum this application
guarantees, which is the shape cards exist to avoid.
TheHostsGridKeepsTwoColumnsAtTheMinimumWithTheDrawerOpen counts columns
instead, and fails at 248.

And a card's text ran past its own border, because a horizontal StackPanel
measures children with infinite width: a TextBlock inside one never learns it
is short of room, so TextTrimming never fires. Both card rows are grids with a
star column that gives way and an Auto column that does not — a hostname with
its tail cut is still the machine you were looking for, where a badge or the
word naming an auth method is not.

The keychain header changed shape for the same class of reason. It was
Auto,Auto,*,Auto with the buttons last, so the slack column was the only thing
absorbing a change of width and five buttons fell off the right edge the moment
the type grew. That is how GENERATE lost the word KEY once already. The summary
sits in the star column and trims now, so the buttons always get their width.

HostSidebarTests became HostGridTests and moved to the grid with the gestures
it drives. docs/design-import-gaps.md gains a v3 section naming the five
toolbar controls in the design with nothing behind them — a view-mode switch, a
tag filter, a calendar, a share control and Serial — and manual-checks.md and
the README follow the controls that moved.

jaap-jan 5800a4bbd0 Give the keychain the DELETE its confirmation was already written for
The counted confirmation has been on this screen since the phone got its
screens, and nothing could raise it. PendingDeletion is armed by
DeleteSelectedItemCommand and its siblings, and the only Delete bindings
anywhere on this head were the files screen's remote delete and the snippets
one — so the card, and the header comment calling it structural, described a
question the phone could not ask. The button is what was missing rather than
anything behind it: the command, the counting and the wording were all already
shared with the desktop.

It sits in row 2 beside that confirmation rather than in a bar at the foot of
the screen, which is where HOSTS and FILES put what to do with the chosen thing.
ShowsItemActions is SelectedItemIsEditable and not-already-asking, so sharing
the row makes the question take the place of the button that asked it, and
DELETE cannot be pressed a second time underneath its own confirmation. A button
at the bottom and its question at the top would be one exchange drawn twice.

DELETE alone, without the EDIT the desktop's detail pane offers beside it,
because there is nothing on this head for EDIT to open. That is also why the
bar names the item rather than trusting the highlight: it is the only thing on
screen saying which row is about to go.

And the highlight had to be made to exist. HOSTS and FILES fill the selected
ContentPresenter, which works because their rows are bare Borders; a keychain
row is Border.card, and the card paints an opaque Sidebar over it. The selector
reaches the card itself instead, in the same Active the chosen host wears, so
the row a button now acts on looks different from the ones it does not.

The TAGS comment said renaming and deleting happened here. Half of that is true
as of this commit and the other half is not — a tag is still renamed on the
desktop, because no kind of item opens an editor on this screen.

The README's paragraph about what the phone is missing said there was no host
editor, which stopped being true when the floating + and both editors landed. It
now names what is actually absent: no local pane for file transfer, no keychain
editor, and no screen at all for pins, teams or import.
2026-08-03 14:54:19 +02:00
jaap-jan a2f0d4813a Take a third off both of the terminal's bars, and centre the cross in a tab
The bar the last commit put above a shell opened at 52 and the accessory row
under it at 50, both inherited from the arrangement they replaced rather than
measured against the one they are in. Neither is carrying a title or a sentence
any more — the top one holds two icons and a row of pills, the bottom one a
line of keys — so a third comes off each: 35 and 33.

Every height inside them came down too. The pills go 44 to 30, the icon squares
34 rather than 44, the keys 38 to 30. A bar that shrank around contents that
did not would not have saved anything; it would have moved the clipping
somewhere harder to see.

Two of those numbers had arguments written against them and both arguments
change rather than disappear. The pill was 44 because it contains the one
control on this head that is destructive with neither confirmation nor undo,
and that is now carried by width — the cross keeps its full 44-pixel column,
and what it gave up is vertical slack in a row where nothing sits above or
below it to be hit by mistake. The keys were 38 for the same kind of reason,
and the 44 that mattered there was always the width: ten keys flexed across
360dp is 32 pixels each, which is what the horizontal minimum exists to refuse.
Both comments say what replaced the reasoning rather than quietly showing a
smaller number.

The close cross was not vertically centred, and it was not a rounding error.
`Button.row` sets `HorizontalContentAlignment` and says nothing about the other
axis, so the glyph sat against the top of its own column while the label beside
it was centred by the stack panel it lives in. On the control that ends a
session that reads as a misprint. Both alignments are now stated, on the button
and on the text.

The `+` loses the accent and becomes the same `Button.icon` as the arrow across
from it. The two are a matched pair at either end of one bar — one leaves this
surface, one adds to it — and an accented one ranked itself above the way out.
The accent fill belongs to the floating `+` on HOSTS, which is the only action
on its screen; this one is not.

Five pixels between the renderer and the keys, as a margin rather than a
border. The renderer is a native child view and nothing Avalonia draws can sit
on top of it, so a hairline there would have to be a row of its own — and a
terminal whose last line of output is flush against a row of grey keys reads as
one surface that has gone wrong rather than as two that are different things.

The four places that named the old bar height are corrected, including manual
check 11.5, which asserted a number that would now fail.

jaap-janandClaude Opus 5 7e4e068aab Merge main into the teams branch
Two conflicts, and both were two people counting the same things differently
rather than disagreeing about what the code should do.

PhoneShell's header comment. The branch made "the five hub screens"
numberless, because TEAMS made it six and a number in that sentence had
already gone stale once. Main corrected "three destinations" to "two" in the
same sentence, because giving a shell the whole phone took the terminal out of
the set the header is drawn on. Both are right and neither noticed the other:
the header now stays on the hub's screens and on the two top-level
destinations, which is Hosts and Keychain.

The manual checks. Both sides appended a Phase 10 — main added the software
keyboard and the phone's terminal surface as 10 and 11, the branch added
Teams. Nothing about them overlaps, so the resolution is to keep all three in
the order they were written and renumber Teams to Phase 12, its subsections
and the one cross-reference inside 12.1 with it. Main's two phases keep the
numbers they already carry in its history, since renumbering those would move
headings somebody may already have linked to.

Everything else merged without a conflict, and the two places worth checking
afterwards both held: IsMoreSurface and the first case of
PhoneShell.OnBackRequested each kept ShellScreen.Team alongside main's edits.
Those two are one fact in two places, so a merge that dropped Team from either
would have trapped the user on the teams screen with the MORE tab dark.

Verified after resolving: solution builds with no errors and no new warnings,
the Android head builds, and every suite passes — App 214, Layout 73, Api 162,
Infrastructure 34, Contracts 25, Session 54. App gained the three shell-flow
tests main brought with it.

jaap-jan 80ae586fc4 Give a shell the whole phone, and one bar to leave it by
A connected phone was drawing five rows of chrome around the thing the user
opened it for. The vault header at 56, the terminal's own tab strip at 52, a
connection line at 36, the shells strip at 46 and the four-entry bottom bar at
64: at 360dp that is about a third of the display, and every row of it was
about somewhere the user was not. What replaces them is one 52-pixel bar drawn
by the surface itself — back on the left, the session pills, and a `+` across
from them — and then the terminal.

Three of those rows belong to `PhoneShell` and each is now bound on
`IsShowingPages`. That is the same question asked once rather than three
conditions that could drift: the surface is either a page or a terminal, and
these are the chrome a page has. The header needed a wrapper because Avalonia's
bindings have no "and" and it already had a condition of its own; the strip
needed one for the same reason. The bottom bar had none and is bound directly.

The back arrow goes to the page the terminal was opened over rather than to
Hosts by name, because the system back gesture already picks that and an arrow
landing somewhere else would be the second of two answers to one question. The
bar's `+` raises a sheet offering the three connections this application can
make — a shell, a host's files over SFTP, a bucket — since SFTP and S3 used to
be two taps through the bottom bar's MORE and the bar is not on screen here. A
control that replaced it and led to one of the three would have quietly removed
the other two.

Two things moved rather than being dropped. The text-size buttons are pinned at
the right-hand end of the accessory key row, outside its scroller: the
connection line existed to keep them from scrolling out of reach, and being
outside the scroller answers that argument rather than abandoning it. The
dialled address moved onto the connecting card, which is the moment it is worth
reading — what is being connected to, before anything has answered — and after
that the shell's own prompt says it more accurately than a header derived from
the keychain ever did.

The sheet collapses the renderer rather than covering it. Whether Android's
`WebView` composites above Avalonia content the way Win32's child window does is
still unverified — `docs/android-port.md` has said so since the port — so this
follows the desktop's palette and gives up the rectangle outright, which is
correct under either answer. It collapses `IsTerminalShowing` and not
`IsTerminalSurface`, because the bar the sheet was raised from is part of that
surface and dropping it would take the bar, the tabs and the whole arrangement
with it, leaving the sheet floating over the page underneath.

`OnSurfaceChanged` is the one place the flag is lowered, and that is the load-
bearing half. Every way out of a terminal ends there — a destination, the files
screen, the palette connecting to a host, closing the last tab, a lock — and
each of them would otherwise leave a sheet set over a page. Not merely untidy:
the flag holds the renderer blank, so the next return to the terminal would
draw the menu again over a rectangle kept blank by it. Opening is refused off
the terminal surface for the same reason from the other direction.

The back gesture gains a guard above the switch, in the shape of the editor
guard that arrived with the phone's `+`. It is nearer than any of them: with no
header and no bottom bar, while the menu is up that gesture is the only way off
it other than the scrim and CANCEL.

The bottom bar's Terminal entry lost its `IsCurrent` binding. The bar is
collapsed on that surface, so the binding could only ever be read as false, and
a rule about a state the control cannot be in is a claim that it can.

Three tests in `ShellFlowTests`, which is where shared state-machine behaviour
for this head goes: the collapse and its recovery, the refusal to open over a
page, and the sheet lowering both by a menu entry and by a route it was never
wired to. Everything visual needs a device, so it is phase 11 of
`docs/manual-checks.md` — and 11.2 is the check that would finally settle the
compositing question this head has carried as unverified since the port.

jaap-janandClaude Opus 5 a43286ece8 Let a team change hands, and be joined by somebody with no account yet
M3 built teams and stopped short of the two operations that decide who
controls one. Both were written down as refusals rather than omissions:
ADR 0009 listed ownership transfer under "deliberately not built", and
design-import-gaps said an invitation needed "a token with a lifetime and an
outbound mail path". One of those reasons had expired and the other never
applied — an invitation does not need a token if it is not a thing anybody
presents.

Handing a team over is one write. The member you name becomes owner and you
become an admin, in a single transaction, because ownership is sole: promoting
first leaves the team owned twice, demoting first leaves it owned by nobody,
and there is nobody left with the authority to finish a transfer that stopped
in the middle. That is also why it is not two calls to the role endpoint, which
refuses Owner outright. The outgoing owner is demoted rather than removed —
removing them would revoke their vault key grants and flag every team vault for
rekey, which is a far larger act than the one asked for, and somebody handing
over a team is usually staying in it. It unblocks the thing that was impossible
before: an owner can now leave, by handing the team on first.

An invitation is a standing instruction rather than a message. This server has
no outbound mail path, so nothing is sent and there is nothing for the invitee
to present. The row says the next account signing in with that address joins
this team at this role, and telling them to sign in is the caller's job over a
channel this server does not carry. A link nobody can deliver would be worse
than none. It lives in its own table rather than becoming a membership with
MembershipStatus.Invited, and that member stays unwritten for the reason it
always was: team_membership.user_id is not nullable and carries a foreign key,
so somebody who has never signed in has nothing for that row to point at.
Widening it would make the unique index on (team, user) meaningless, because
PostgreSQL counts every NULL as distinct.

Verification is the security boundary, and nothing in this server read it
before. A claim requires the access token to assert email_verified. An
invitation decides what the server will serve, so one claimable by anybody able
to obtain a token carrying somebody else's address is a way into a team — which
is precisely the attack OidcOptions.AllowEmailLinking exists to refuse, and it
would have been reintroduced by the back door. There is deliberately no setting
that relaxes it: a flag that exists is one somebody turns on for the afternoon
their provider is misconfigured. Absence is refused rather than trusted, and
logged, because a provider that never sends the claim otherwise leaves every
invitation pending with nothing anywhere saying why.

Claiming happens at just-in-time provisioning and again on an hourly sweep. The
sweep is what makes it recoverable rather than one-shot — an invitation issued
between an account being created and that person next signing in would
otherwise be stranded for ever — and it shares its rate with the last-seen
write because both are housekeeping nobody is waiting on.

Archiving is refused while a team owns a vault, and that refusal is the end of
the road rather than a step on it. A team vault is readable because of
membership, so archiving one that still owned vaults would take them away from
everybody holding a key, including the caller, quietly and all at once. Nothing
in this product deletes a vault, so no order of operations gets past it today —
which is stated with a count of what is in the way, for the reason the SFTP
layer refuses a recursive delete: a refusal is visible and a quiet removal is
not. It is owner-only, as handing over is; renaming is not, because a rename is
visible to everybody and reversible by anybody who can do it. The slug is not
renameable at all: it is unique only among live teams, so a rename could take
one an archived team is still holding, and that team could then never be
restored.

LAST ACTIVE is real and coarse on purpose. UserAccount.LastSeenAtUtc is
refreshed on ordinary authenticated requests, at most once per account per
hour, through ExecuteUpdateAsync — user_account carries the xmin concurrency
token, so a read-then-write on the hot path would start losing races between
one user's own overlapping requests. An hour is the granularity the question is
actually asked at, and the interface draws it to the day rather than the minute
so it does not read as a precision that is not there. The remarks in Contracts
and in the view model that argued at length for the column's absence are
rewritten rather than extended; both had become false.

Two endpoints already existed and nothing called them. ChangeTeamMemberRole and
ListVaultGrants have been reachable since M3. The role picker refuses Owner
itself rather than letting the server do it, since the interface already knew
the rule; the key-holder list sits under the vault rather than beside the
member, because a grant is per vault and a count on a member row would imply
per-item sharing, which is M5. It lists withdrawn and stale grants and says
which they are — a list that dropped them would show a departed colleague as
merely absent rather than as somebody whose key was taken away — and staleness
is decided by comparing generations, since a grant can be Active and still open
nothing.

ADD MEMBER stopped being a dead end. An address the directory did not know used
to end at a sentence telling the user their colleague had to sign in first. It
invites them instead, from the same button, because which of the two applies is
a fact about the server's account table rather than about what the user is
doing; which one happened is reported afterwards, because that decides what
they do next. An address that merely has an account is invited rather than
refused: refusing would have made the endpoint an oracle for which addresses
have accounts here, answerable by anybody willing to create a team first.

The phone has a TEAMS screen, behind MORE, and it is the reverse of every other
row in design-import-gaps: a shipped screen the design had no slot for. It is
there because an invitation is claimed by signing in, so somebody told they are
now in a team is at least as likely to be holding a phone — and a membership
visible only on a head they never installed is one they cannot see. It draws
SHARE KEY and nothing that takes something away: wrapping a key is the one act
on that screen a server cannot perform at all, and the desktop guards its
revocations with a tooltip, which is a control a touch screen cannot show.

Two defects were found by an adversarial pass and both were green against the
whole suite at the time. The owner-only check on archiving and handing over had
been weakened to the admin check while their messages and comments still said
owner — and since nothing behind the archive endpoint re-checks it, an admin
the owner had promoted could have archived the team out from under them. And
the rename endpoint built its response with a hardcoded Owner role, so an admin
who renamed a team was handed a summary claiming they owned it, and a client
trusting that instead of re-listing would have offered them the two owner-only
buttons the server then refuses.

The new table gets its constraints tested rather than merely migrated: live
uniqueness per (team, address), the citext proof that an address typed by a
person matches one cased by a provider, and reissue after both revocation and
acceptance. The teams screen gets its first entries in the layout suite, at the
minimum window with every list populated and with each of the two states that
cover half of it — it had none, and it just grew four sections and a second
line in the member row.

jaap-janandClaude Opus 5 4925dcf179 Give the phone the + it was promised, and the editors behind it
Steps 5 and 6 of docs/adding-hosts-on-the-phone.md, which finishes it. The
phone can now put things in a keychain rather than only read one.

The floating + arrives three designs after it was first asked for. It was
refused twice on the honest grounds that it would open an editor this head had
not got — and that stopped being true when steps 1 to 4 landed. It raises a
sheet rather than a form, because "add" on this screen has been two operations
since groups existed: a host, or a group to file hosts under.

Both editors are cards in the list's own row, swapped for the list rather than
stacked over it, following SnippetsScreen and for the reason written there: a
form on top of the list hides what it is about. There is still no dialog and no
editor screen anywhere on this head. The port and username boxes may be left
empty, and the greyed text inside each is what the host will actually use —
following the group picker as it moves, so the form says what leaving a box
blank will do rather than making it a guess.

The back gesture gains a guard above the switch rather than a case inside it.
An editor is not a screen and has no entry there, and it is strictly nearer:
the sheet sits over the editor's own screen, so back lowers whatever is topmost
before it considers moving between screens.

A group editor needs a way in, and the phone draws no groups panel — so the
heading in the host list gains a pencil. A + that adds groups with no way to
correct one is the same strange thing to ship as one that adds hosts with no
way to correct one, and worse: a group's defaults are what every host beneath
it falls back to.

Scouting step 6 turned up a bug worth more than the prose it was looking for.
ReloadGroupsAsync read the active vault alone, which was a cosmetic limitation
while a group carried only a name — a teammate's host showed under UNGROUPED
and nothing else was lost. Since a group began lending a port, a username and a
binding, the same omission silently dropped all three: that host would dial 22
as nobody while the machine is on 2222 as deploy, with nothing on screen saying
why. The resolution map now spans every readable vault. The editable list stays
narrow, because a row shown across vaults needs a vault id for rename and
delete and two vaults may hold groups with one name — but the map needs none of
that, since it is only ever asked what an id says.

An adversarial review of this change found something I had written a comment
denying. The + was a child of the outer Panel rather than of the list's row, so
it anchored to the bottom of the screen and sat squarely over the new EDIT
button and the lower edge of CONNECT — and because a Panel hit-tests its
last-declared child first, tapping the right end of EDIT would have raised the
add sheet. The comment beside it claimed it was in the list's row precisely so
that could not happen, and manual-checks 8.1 names that exact failure. It is in
Grid.Row 2 now. The same pass caught a connect bar that was disabled rather
than hidden while its own comment said hidden, a scrim that would have flashed
its default pressed chrome across the screen, a fab comment claiming an accent
fill no other button had when Button.primary has it, and a back-gesture remark
naming two view-model properties that do not exist anywhere in the repo.

That last one came from this plan, which invented IsVaultsSurface and
IsConnectionsSurface, and pointed step 6 at a ConnectionsScreen.axaml that has
never existed. Both are corrected in the plan rather than quietly worked
around, along with a fourth "groups are flat" site in README.md that step 1
missed.

The phone's rectangles are not measurable and structurally never will be: the
layout suite is net10.0, the Android head is net10.0-android, and Avalonia's
application is a one-shot process global — so a second head cannot share the
process even if the reference were possible. Everything the sheet and both
editors bind to is shared and is tested headlessly here; the pixels go to
docs/manual-checks.md phase 8, nine checks, which is where this project already
sends what it cannot assert.

Tags remain the one thing asked for that did not ship. Tag is a full item kind
and TagIds merges, encodes and resolves, but no screen draws a chip or offers
to add one, so the tags a client can store are ones nothing here can see. Both
editors carry the set through a save untouched so a client that can set them
does not lose them. Recorded as half-shipped in docs/design-import-gaps.md
rather than quietly left out.

Verified by the whole suite: 1402 tests over nineteen projects, none failing.
Both heads build. Nothing seen on a display — phase 8 is what that costs.

jaap-janandClaude Opus 5 3627021420 Give the desktop the second design too, and the window the size it now needs
The desktop v2 design is the other half of the one the phone took last commit, and this is its chrome: a
190-pixel labelled sidebar where the 54-pixel icon rail was, a titlebar with the search box centred in it,
and session tabs drawn as pills. The palette was already here — it is shared, and moved when the phone's
did — so what this changes is shape rather than colour.

**The window's minimum grew, and by exactly what v2 added.** The sidebar is 136 wider and the chrome 14
taller, so 880x560 became 1016x574. That is not a round number somebody liked: it leaves every screen the
same 826x464 it was designed against, which is the arithmetic the layout suite is built on. Four of the
tables stop fitting at 690 wide, so widening the sidebar and leaving the window alone would have broken
them somewhere no test was looking. LayoutHarness carries the new constants and the suite still passes at
the minimum, which is the whole reason it exists.

The rail's five-character abbreviations are gone with the width that caused them — PINS and SNIPS are Pins
and Snippets again — and each row gains a glyph and a count. A count is drawn only where one is real, so
SFTP, Logs and Preferences show nothing rather than a zero: a transfer queue's depth is not how many files
a screen holds, and a log has no total until it is read. The count beside Pins is the vault's own, not the
Pins screen's VisiblePins, which is the filtered list and would have made the sidebar count whatever
somebody had just typed into a filter box on another screen. Teams has no count for a related reason: they
are read from the server when that screen is opened rather than on unlock, so a number there would read 0
until somebody had already been to look.

One colour moved with it, finishing what the repalette started: the live-session summaries on the unlock and
sign-out cards were Info, so the two heads disagreed about a fact the phone paints green. They match again.

**Buckets became a destination rather than a mode**, which is what the design draws and what the phone
already does. The HOST / BUCKET pair inside the files screen is gone; ShellScreen.Buckets draws the same
TransfersScreen with the other picker, and the sidebar entry is what sets it. That also settles an old
disagreement rather than merely moving it: TotalItemCount is keys plus passwords and excludes buckets, so
the number beside the keychain used to disagree with the list under it, and now counts what that screen
shows.

There is one session behind both file destinations, so asking for the other kind while something is open is
refused rather than obeyed — and refusing means staying put. An earlier turn of this had it move anyway and
only decline to switch the picker, which put the S3 entry in the sidebar over a screen still listing an
SFTP host: two pieces of chrome disagreeing about where you are, which is worse than the navigation simply
not happening. The message that says so goes to Transfers.Status, which turned out to be drawn in the same
grid cell as the connected chip — survivable while it was mostly read before connecting, and not once a
refusal reports itself there. It has its own column now.

The design has nine entries' worth of screens and draws five. Pins, Teams, Import and Preferences are
built, working screens, so they keep their entries — the sidebar is labelled now and has the room, and
dropping an entry would have stranded a screen rather than simplified anything. The Team vault card the
design pins to the foot is not drawn: it is a second route to a screen already in the list, carrying a seat
count nothing here produces.

**The status bar survives the design that deletes it**, cut down to one thing. Two of the three facts it
carried moved into the titlebar with v2 — the sync word is beside its dot and the shortcut hint is inside
the box that uses it — so those are gone from it rather than printed twice. The third is Vault.Status, the
only channel this application has for saying a save failed or a merge picked a winner. The design is a
mock-up of an afternoon that goes well and has nowhere to put a sentence like that; dropping the bar would
have meant dropping the sentence or repeating it on nine screens.

What v2 draws and this does not is in docs/design-import-gaps.md, and it is the same list as the phone's
for the same reasons: the forwarding screen and both its chips, the host detail's fingerprint, tags and
last-session cards, the keychain's rotate button, the logs' FOLLOW pill and severity filters, and the
session footer's latency. The terminal is not inset behind a rounded frame either — it is a native child
window that composites above everything Avalonia paints, so the frame would clip nothing, which is the same
answer the phone gave.

**The light theme is not built.** Its accent is #6D5AE6, a different hue rather than a tint of the dark
one, so it needs every colour doubled, a variant to switch on, the renderer's own page switching with it,
and contrast checked twice. That is a piece of work rather than a setting, and it is separable from the
layout — which is why this commit is the layout.

The screens themselves are restyled through the shared vocabulary rather than rebuilt: corner radii,
chips, cards and the accent's ink, all in App.axaml, so every screen moves at once. Their layouts are left
alone deliberately. The design draws read-only detail panes and these screens carry the editors and forms
it has no equivalent of, so replacing a layout with the mock-up's would have lost the half that is
actually used.

Verified by the whole suite: 1309 tests over nineteen projects, none failing, including the 68 layout cases
that stand up real Avalonia and measure every screen at the new minimum. Both heads build. Not run on a
machine with a display — see docs/manual-checks.md for what wants looking at.

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

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

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

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

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

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

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

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

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

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

jaap-janandClaude Opus 5 ffab2be22a Drop the formatting step, which spent minutes agreeing with the build
ci / build and test (push) Successful in 1m11s
ci / android head (push) Failing after 4s
ci / api image (push) Successful in 43s
`dotnet format --verify-no-changes` re-analysed the whole solution before the build did, to
reach a verdict the build reaches on its own: IDE0055 is an error in .editorconfig,
EnforceCodeStyleInBuild is on and warnings are errors, so a misformatted file fails the
build step. What the separate step bought was hearing about it a few minutes earlier, and
it charged those minutes on every run.

Checked rather than assumed, because the whole justification rests on it: appending a
badly-spaced member to a source file produces three `error IDE0055` lines and a failed
build with no format step in sight.

Three places said the old arrangement out loud and would now be wrong on their own — the
comment on the IDE0055 line, the conventions list in the README, and a note in
platform-flags telling people to run dotnet format before pushing or CI would fail them.
They say the build enforces it now. dotnet format is still how to fix what the build
complains about; it just no longer gates anything.

jaap-janandClaude Opus 5 093f3904c1 Apply pending migrations at startup instead of asking for a second command
ci / build and test (push) Failing after 1m48s
ci / api image (push) Skipped
ci / android head (push) Failing after 5s
The API deliberately never migrated: it failed readiness while a migration was pending and
named it, and a separate step applied them. That is the right split for a deployment with a
release pipeline and the wrong one for a self-hosted server, where it means an image that
boots, refuses traffic, and waits for somebody to know that dotnet ef exists. The schema and
the code that expects it ship in the same image, so the image is where the two are
reconciled now.

Before RunAsync rather than in the background. A migration racing the first requests would
let them through against a half-applied schema, and the first authenticated request is the
one that provisions accounts. Failing to migrate therefore fails to start, which is the
loudest signal available and the one an orchestrator already acts on.

Concurrent starts take a Postgres advisory lock first. Without it two replicas rolled out
together read the same empty history table, both apply the same migration, and the second
dies on an object that already exists — a crash loop on the day of a schema change, which
is the worst day to have one. The lock is held on a connection of its own because EF opens
and closes one per command, and a session lock belongs to the connection that took it.

The exception is a database that does not exist yet: there is nothing to hold a lock in, so
that path migrates without one and says so. Two instances creating it at once still
converges — one wins, the other restarts into the ordinary locked path — and refusing to
start would leave a fresh deployment stuck on the step this removes.

Database:AutoMigrate turns it off for the deployments that own their schema: a migrator job,
a rollout where new code must run against the old schema first, or a database user denied
DDL. With it off the behaviour is exactly what it was, and the health check now explains
which of the two situations a pending migration means.

Verified against a throwaway PostgreSQL container: an empty database gets all seven
migrations applied before the port opens, the tables land in the dodo schema, and a second
start logs the schema up to date and serves. The API suite passes, which exercises the
startup path once per assembly.

jaap-janandClaude Opus 5 43d76d0f2d Let the suite run on Linux, and fix the three things that stopped it
ci / build and test (push) Failing after 1m47s
ci / api image (push) Skipped
ci / android head (push) Failing after 5s
The pipeline finally reached the tests and found four failures. None was the pipeline's,
and only one of the four was a test being fussy about a platform rather than telling the
truth about one.

The local pane's roots bar was the real bug. LocalDirectory.Roots built it from
DriveInfo.GetDrives on every platform, and its own summary — "the drives on Windows, and
the root elsewhere" — had been describing an intention rather than the code for as long as
nobody ran it off Windows. On Unix that call answers with every mount the kernel holds:
/proc, /sys/fs/bpf, one per installed snap, /run/user/1000/doc, some forty on an ordinary
laptop. The transfers screen draws a button per root, so the bar ran to about five thousand
pixels inside an eight-hundred pixel window. Anybody running the Linux build has been
looking at that.

Filtering GetDrives is not the fix and the comment now says why at length, because it is
the obvious thing to try: DriveType answers Fixed for / and /home and equally for every
squashfs snap, for efivarfs and for tracefs, while /boot/efi comes back Removable, and
DriveFormat would need a hand-kept list of every virtual filesystem Linux might grow. So
Unix now names what somebody would want instead of subtracting what they would not — the
root, their home, and whatever is mounted under /run/media/<user>, /media, /mnt or
/Volumes. Anything else is still reachable by navigating from /, which is what the pane is
for. Windows is untouched.

ClientPathsTests looked for "odoSSH" in the profile directory. ClientPaths spells it
DodoSSH on Windows and dodossh on Unix deliberately, one per platform convention, and that
substring was clever enough to survive either spelling of the leading D while still only
ever matching one of them. Now OrdinalIgnoreCase.

WhyTheWindowItselfIsNeverShown asserted a COMException with HResult RPC_E_CHANGED_MODE,
which is WebView2 refusing an MTA thread — a Win32 component raising a COM error. On Linux
the adapter is a different implementation with no apartment to disagree about, so showing
the window works and Should.Throw catches nothing. Skipped there rather than loosened to
accept both outcomes: the assertion is the documentation in that test, and one that passed
everywhere would have stopped recording the constraint it exists to record.

The fourth was CI's alone, and the diagnosis is the useful part. All 69 layout tests failed
on the runner while 6 failed here, which looked like missing fonts and was not: Avalonia's
headless renderer is Skia, libSkiaSharp.so links against libfontconfig, and without it the
suite dies in HeadlessUnitTestSession with a TypeInitializationException on SKImageInfo
naming none of its actual subjects. The job installs the one library now. Verified in a
container where fc-list returns zero and the suite passes regardless, because the
application carries Inter itself — fonts were never the problem, only the thing that would
have looked for them.

The whole solution now passes on Linux: 19 suites, 1295 tests, 0 failures, 4 skipped, the
end-to-end Testcontainers suite included. README and platform-flags.md said testing was
Windows-only, which CI now contradicts on every push, so both say what is true instead and
the two findings are written down where the next person will look for them. macOS is still
untested and now says so on its own rather than hiding inside "not Windows".

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

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

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

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

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

jaap-jan 81e7e6d939 Write down what the phone found, and stop it rotting
docs/android-port.md was an audit of work not started; it now says what is built. Three of
its statements needed correcting rather than extending, and they are marked where they sit:
the Android version question is settled and was never as open as it looked, because
Avalonia.Controls.WebView ships only a net10.0-android36.0 assembly and nothing lower can
resolve it; cleartext to loopback has to be permitted explicitly, which the audit missed
entirely; and the spike produced a structural change it did not anticipate, in
DodoSSH.Client.Shell.

A CI job of its own, because the head is deliberately not in DodoSSH.slnx and a project
outside the solution is a project nobody notices breaking. It packages as well as builds:
a native library with no Android ABI and an assembly that will not dex are both invisible
to a compile, and both are exactly what this head is exposed to.

The README says plainly that signing in is not built, that a fingerprint re-enrolment
destroys the device key, that a notification appears while a shell is open, and that none
of it has run on a device.

jaap-jan 5cbda59a34 Merge branch 'main' into claude/host-management-ui-plan-7f20ab
Seven files needed a hand. Most were two branches adding something in the same
place, but three were one branch changing what the other had moved or renamed,
and those are the ones worth reading.

The shell keeps both new fields and both constructor lines: the connection
recorder this branch built and the teams view model main did. Where main put a
teams load inside OnScreenChanged, it now sits beside the logs refresh rather
than inside RaiseSurfaceState — this branch extracted that notification block
and it is called from two properties, so a screen-specific side effect in there
would fire on every terminal switch as well.

Main gave four row types a vault id and a vault name, and this branch had moved
one of them — KnownHostRowViewModel — into its own file when the pinned keys
became a screen. Git resolved that as "deleted here, modified there" and took
the delete, which compiles as long as nobody looks: the moved copy still had
the two-argument constructor and the call site had grown to four. Carried over
by hand, along with the ordering the pins list now does on them.

The status line's quiet rule was the subtle one. Main extracted it into
IsWorthReporting; this branch had changed the same condition to read item
counts rather than raw ones, because every user action queues a log entry a
moment later and this machine reads its own entries back on the next pull. Take
main's structure and the merge builds, passes, and silently restores a bug this
branch existed partly to fix — every save's message overwritten a second after
it appears. The method now reads PulledItems and PushedItems, with the reason
in its remarks.

Two conflicts were prose that had gone stale rather than code. The keychain
screen's comment said team vaults are refused by the server's access service,
which was true when it was written and is not now; main's replacement stands,
in this branch's vocabulary. The design-gaps row for groups was claimed by both
— real host groups here, per-vault headings there — and they are different
things, so both rows stay and the difference is stated: a group is a shelf the
user chose, a vault is who can read the item.

One defect the tests found and the compiler could not. Generating a key opens
the same editor as pasting one, but not through NewKey — so it never set the
target vault main added, and a generated key was filed into whatever vault was
edited last, or none. Both key-generation tests failed on it. Fixed where the
editor opens, with the reason recorded there.

One gap is left deliberately and is written down rather than half-built. Hosts,
keys, credentials and pins are read across every vault this session holds a key
for; groups are read from the active vault alone, so a host a teammate filed
shows under UNGROUPED. Nothing is lost or misfiled — it is what the sidebar
already shows for a group that has been deleted — but closing it needs a vault
id on every group row for rename and delete, and a way to tell two vaults'
identically-named groups apart under a layout with one heading per group. Both
are worth doing and neither is a merge's business. It is in the remarks on
ReloadGroupsAsync and in docs/design-import-gaps.md.

dotnet build, dotnet test and dotnet format --verify-no-changes are all clean:
1282 tests, including the end-to-end suite against real containers.
2026-07-31 20:44:39 +02:00
jaap-jan d07b336868 Free the terminal from the Hosts screen, and fill the room it left
The WebView sat inside the Hosts grid, so navigating to Files or the keychain
hid every open terminal and the strip that named them. A connection you had
opened was invisible from four of the five screens. The window now has two
surfaces rather than one: a nav rail that says which page you are on, and a
terminal strip that is always there and switches the whole content area to a
shell. Screen keeps meaning "which page" and never becomes a sixth kind of
page, which is why this is two properties instead of one enum with a terminal
member in it.

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

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

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

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

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

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

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

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

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

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

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

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

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

jaap-jan 23eca3a21b Merge branch 'main' into claude/m3-implementation-57f9d7
ci / build and test (push) Failing after 2s
Three files conflicted, and two of the resolutions are more than a choice of
side.

QuickConnectTests had both branches fixing the same build break — main's M2
merge left the shell's constructor with an ISftpSessionFactory nobody passed.
Main's version wins because it carries a comment saying why the palette never
needs a session.

VaultSession's conflict is adjacent edits: main added the remembered sign-in
members and this branch changed SyncAsync's summary from "the active vault" to
"one vault". Both kept.

VaultViewModel is the one that matters. Main taught the background pass to
report a sync that had to start over, on the grounds that a machine which
silently re-read a whole vault has had something happen to it; this branch
turned a pass into one report per readable vault. Taking either side alone
would have lost the other, so ResyncedFromStart is now one of the conditions
IsWorthReporting checks, per vault.

Merging also broke something neither branch could have caught alone, and the
build would not have said a word. SyncOnceAsync cleared LastSyncFailed
unconditionally, which was right while a pass was one vault and a failure was
an exception that never reached that line. A failure is now a report — one
unreachable team vault must not stop the others syncing — so the flag was being
cleared over a vault that had just failed, lighting the titlebar SYNCED. It is
computed from the report instead, in the one place both callers go through, so
the manual command gets it as well as the loop. The background pass still
swallows the message and keeps the fact, which is what
AnAutomaticPassThatFails_LeavesTheStatusAlone is there to hold it to.

Two comments the auto-merge left describing a world with one vault in it: the
SCOPES rail's, which said team vaults are refused by the access service, and
the host sidebar's "One heading, for one vault".
2026-07-31 12:26:59 +02:00
jaap-jan 95816de0c5 Share a vault with a team, without the server holding a key
M3's teams, sharing and ACLs. Teams with roles, a public-key directory, the
append-only key log served for clients to check it against, team-owned vaults,
and vault key grants wrapped by a client and stored opaquely by the server.
VaultAccessService resolves team membership to PermissionFlags, so a viewer may
pull and may not push; the desktop client reads and syncs every vault it holds
a key for, and a real TEAMS screen replaces the one that said it did not exist.
No migration: team, team_membership, vault.team_id and vault_key_grant have all
been there since the first one, which is what carrying two unused tables bought.

Membership is authorisation. A grant is access. The obvious model is one
concept — "access", with a role attached, handed out by the server — and this
architecture cannot implement it: a vault key is sealed to each member's X25519
key, and only a client holding the plaintext can seal it for somebody else. So
"give Bob access" decomposes into a database write and a wrap, which happen on
different machines. Adding a member makes the server serve them the vault; it
cannot make it readable. VaultSummary.WrappedVaultKey is null in the meantime
and the vault appears in their list saying it is waiting for a key, because
hiding it until a grant existed would have been tidier and would have implied
the server was the thing granting access. The screen says the same thing after
every add, in the status line. ADR 0009 records the whole decision.

Sharing verifies or refuses. A directory lookup is a claim by the server about
a third party's public key, and wrapping to an unverified claim hands the vault
to whoever made it — no amount of transport security helps, because the server
is inside the threat model. KeyLogAudit reads the whole log, recomputes every
entry's hash from its own contents, checks the chain from genesis, and refuses
unless the offered key appears in it unchanged. There is no override flag: one
that exists gets used on the day the log is briefly unreachable, and the
resulting grant is indistinguishable from a correct one afterwards. What it
still cannot promise is that the key is the right person's, so the fingerprint
comes back for an out-of-band comparison and the success message says so every
time. A test corrupts the fake server's log by one byte and watches the client
refuse rather than warn.

The roles are only the ones that are enforceable. There is no ConnectOnly,
despite the design asking for one and TeamRole having room: SSH terminates on
the client, so a session needs the credential's plaintext on that machine, and
"may connect but may not read the key" cannot be enforced here. Shipping it as
an option in a dropdown would have been a lie. Connect rides along with Read
and is documented as an interface hint. Removal is named for what it does — it
revokes grants and flags the vault for rekey, and claims nothing about what is
already on somebody's laptop.

Three things are deliberately absent, and each is a refusal rather than an
omission. The rekey itself, because re-wrapping every item's data key under a
new vault key needs a client holding the current one; the server records that a
rotation is owed and the interface reports it, which is more honest than a
button that only appears to do it. Ownership transfer, because allowing an
owner to be removed without one leaves a team nobody can administer. And
cross-vault host key trust: a pin in a team vault is listed but not consulted
at connect time, because any member with Write could otherwise pre-approve a
fingerprint another member's client then trusts silently for a host in their
own vault. Scoping trust properly needs a scope on the SSH connect path, which
IKnownHostStore has not got; until then the narrow direction is the safe one
and the cost is in the README rather than hidden.

Reading now spans vaults and writing still does not. Every list on the vault
and hosts screens covers each vault the keyring opened, rows carry the vault
they came from, and an edit goes back to that vault rather than to the active
one — writing it to the active vault would fork the item and only show up when
a colleague wondered why their change never arrived. A new item goes wherever a
picker says, defaulting to the personal vault and never moving on its own,
because an item filed into a team's vault is visible to that team and moving it
back means deleting and retyping. The sidebar heading stops naming one vault
once there are two, and each row names its own.

The server checks what it can and nothing it cannot. It will not record a grant
for a key its recipient no longer holds, for a superseded generation, or for
somebody who is not in the team — each of those would otherwise surface days
later at the far end as a tag failure indistinguishable from corruption. It
does not verify the wrap or the signature, and the grant service says so: that
would be a convenience and never the boundary, and would put an asymmetric
implementation on a machine that is supposed to hold no keys.

Two bugs the tests found. TeamsViewModel's busy gate blocked its own reload, so
a team created a moment earlier was missing from the list it had just been
added to. And syncing every vault turned a failure from an exception into a
report, which made a background pass announce an unreachable vault once a
minute — the exact behaviour AnAutomaticPassThatFails_LeavesTheStatusAlone
exists to prevent. The fact is recorded and the message swallowed, as it was
before; pressing Sync still names the vault and the reason.

Also fixes a build break this branch started with: QuickConnectTests was never
updated when M2 added ISftpSessionFactory to the shell's constructor, so
nothing built at all.
2026-07-31 12:18:28 +02:00
jaap-jan 91438fb382 Ask before deleting, and connect a host by double-clicking it
DELETE on a host, an SSH key, a stored password or a file on the host now puts
a question where the button was, and only answering it deletes anything. It is
a state rather than a dialog, which is the arrangement signing out already had
and for the same reason: this is the moment that has to be able to say what is
about to go before it goes.

What the question says is counted rather than generic, because a confirmation
that only asks whether you are sure is a click to train people out of. A key
names the hosts that authenticate with it and says they will refuse to connect
afterwards rather than falling back to a typed password, which is what the
connect path actually does. A host discloses a terminal open on it, because
deleting the host does not close the session. Every vault deletion says how far
it travels and whether this machine can push the tombstone yet or is queuing
it. Deleting on the host carries the strongest warning of the four on purpose:
everything else here is a tombstone against a copy the server still holds, and
a file on somebody's machine is bytes with nothing behind them — so that one
names the full path, since a bare name identifies nothing.

The armed request carries the item's entity id, so nothing that moves the
selection between the question and the answer can redirect it, and answering
about something that has since gone says so instead of doing nothing quietly.
Disarming compares ids rather than rows, which is the subtle half: a reload
replaces every row object, so the naive rule would have let the pass that runs
every minute take the card away from somebody halfway through reading it.

Forgetting a pinned host key is deliberately still unguarded. It costs one
fingerprint check on the next connection and it is the safe direction to be
wrong in — the dangerous button there is the one that adds trust, and that one
is already a prompt at connect time. Discarding a stopped transfer is likewise
unguarded: it removes a resumable part file and leaves the source alone.

Double-clicking a host in the sidebar connects to it, wired as a gesture in the
control exactly as the transfers screen opens a directory. CONNECT stays, since
it is the button with the password box beside it.

Ten existing delete call sites now go through arm-and-confirm helpers, and
eight new flow tests cover asking first, cancelling, the counted warning,
disarming on a selection change and on an editor opening, surviving a sync, and
the stale-item guard. Three layout tests measure the new shapes — the sidebar
card is the one card in the application a user cannot scroll — and one of them
also asserts the card renders its text, because a card whose compiled bindings
did not resolve would lay out perfectly as empty rows. The double-click test
performs the real gesture and proves it reached the connect command through a
refusal that never touches a network.

jaap-jan 240aadb746 Merge branch 'main' into claude/vault-unlock-logout-autosync-a84c35
ci / build and test (push) Failing after 3s
Four files needed a hand, and all four were two branches adding something in
the same place rather than either changing what the other did.

The shell's constructor now takes both new parameters: main's SFTP session
factory, which it must have because it builds the transfers view model, and
this branch's optional resume handler, which stays last so every existing test
that constructs a shell without one still gets a shell that can only be online
because somebody signed in during this run. App.axaml.cs, ShellFlowTests and
QuickConnectTests pass the pair; the layout suite keeps both of its new fields.

Signing out now detaches the transfers screen exactly as locking does, and the
confirmation says that an open transfer session survives it. That is the same
policy both sides already argue for their own case: signing out destroys this
machine's copy of the vault, not work that authenticated before it.

QuickConnectTests did not compile on main — the SFTP commit added a constructor
parameter and the quick-connect suite, merged from a parallel branch just
before it, was still calling the old one. Fixed here rather than worked around,
since the merged tree has to build.

Three things a machine that has been set up could not do. Unlock now takes
Enter, which is the gesture everybody makes after typing a password and which
did nothing until they found the button.

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

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

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

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

jaap-jan 04faef6597 Move files to and from a host over SFTP
M2's file transfer, built bottom-up: an SFTP session on the SSH layer, a
transfer queue in a project of its own, and the two-pane browser the design
asked for replacing the screen that said it did not exist. Remote listings
carry names, sizes, modification times and a real drwxr-xr-x — nothing in this
repository could render a POSIX mode before — and the queue moves one file at a
time with progress, throughput and resume.

The design import assumed this would be an SFTP subsystem channel on
ISshConnection, beside the shell on a transport that is already up. SSH.NET
does not offer that: SftpClient derives from BaseClient and owns its own
transport, and there is no supported way to hand it an SshClient's session. So
file transfer opens a second authenticated connection, and it is named for
that rather than dressed up as a channel — OpenSftpAsync is on
ISftpSessionFactory, not on a connection. The difference is visible to a user:
the host records a second login, and a host whose password is typed each time
asks for it again on this screen. It goes through the same host key gate, the
same pin and the same two refusals a shell does, so a fingerprint approved for
a terminal is approved here and one approved here reaches the other machines
with the next sync. docs/design-import-gaps.md is corrected, and marked as the
one row where what shipped differs from what it predicted.

Nothing is written at its final name until it is complete. Every transfer goes
to a .dodossh-part file beside its destination and is renamed into place at the
end, so an interrupted transfer can never be mistaken for a finished one —
which matters most for what this screen is actually for, which is copying a
build artefact onto a server and then running it. A destination that already
exists is refused outright rather than overwritten: the queue has no way to
ask, and silently replacing a file somebody's process is serving is the worse
of the two failures. The remote pane has DELETE and MKDIR so that refusal is
not a dead end. A test against the container pins the assumption underneath all
of this — that SFTP's rename does not clobber.

Resume works within a run of the application and not across a restart, and the
limit is deliberate rather than unfinished. Nothing records which source wrote
a part file, and resuming one on the strength of its name matching is how a
corrupt artefact gets delivered with nothing reporting a failure; a part file
found at startup is started over. Making it survive a restart needs the
preferences store this client still has not got. The offset a resume starts at
is the part file's own length rather than the transfer's recorded progress: a
cancellation can land between a write completing and the counter moving, and
only one of those two is a fact about the bytes that are there.

The queue and its connection outlive a lock, as shells do. LockAsync already
argues that locking must not destroy work in flight — it is what somebody does
when they walk away from the machine, which is exactly when a long transfer is
most likely to be running — so TransfersViewModel is created once and the vault
is attached on unlock and detached on lock. What locking takes is the host
list, and it has to: those rows carry decrypted secrets.

DodoSSH.Client.Transfer is a new project rather than more of Client.Ssh. The
two answer different questions — one is about reaching a host, the other about
moving bytes and what to do when moving them stops halfway — and this is the
only client project that deliberately touches the local filesystem.

Three defects the tests found, none of which review would have. SftpPath.Name
answered an empty string for the root. NavigateRemoteAsync wrapped itself in
the busy guard, so navigating from inside another command did nothing at all
and the remote pane simply stayed empty after connecting, with no failure
anywhere to explain it. And opening an SFTP session per test made two
handshakes per test — this client learns a host key by being refused — which
pushed the SSH assembly past sshd's MaxStartups and failed a different few
unrelated tests each run; the session is shared through the fixture now, with
the reason written where the next person will hit it.

1004 tests green across 18 projects, 24 of them new: the SFTP subsystem against
the OpenSSH container, the queue against a real temporary directory and a fake
host, and three more layout measurements because a screen this window has never
laid out is a screen never checked.

Not verified: the screen has not been looked at running. The layout harness
measures it at the window's minimum in three shapes, which is the class of
defect that has shipped here before, but reaching it in the application needs
the compose stack, the migrations, the API and a browser sign-in. What is still
absent — the status bar's transfer count, dragging between the panes,
transferring a directory, and sftp over a bastion — is in
docs/design-import-gaps.md.

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

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

jaap-jan 211eba0666 Keep host key trust in the vault, and make it withdrawable
ci / build and test (ubuntu) (push) Canceled after 0s
ci / build (windows) (push) Canceled after 0s
A fingerprint approved once is now approved on every machine and survives a
restart, because host key trust is a vault item type rather than a dictionary
that dies with the process. InMemoryKnownHostStore was what shipped, so the user
was asked to verify a fingerprint on every single connection — which is the gap
most likely to train somebody to click through the one warning that actually
matters. A warning that appears when nothing is wrong teaches that nothing is
ever wrong.

The fourth item type, and like the third it cost no sync logic: a row, an EF
configuration, a migration, a server kind; a secret, a codec, a merge, a cipher,
a repository facade and a session property. One row in the client registry. The
reconciler, the mirror, the repository, the outbox and the pull filter were not
touched. SyncEntityType.KnownHostKey and AadResourceType.KnownHostKey were
already reserved, so neither the contract nor docs/crypto.md changed.

One item per (host, port, algorithm), because a server legitimately offers
several host keys and which one gets negotiated is not ours to predict. Pinning
per endpoint would make an algorithm change indistinguishable from an attack.

The label is derived rather than stored, which is the one place this type
departs from the other three. A user never names a pin — there is nothing to
name it after but the three fields it already has — and a stored label is a
second copy of data that can disagree with the first after a merge. Relabel
returns the secret unchanged, and says why.

The store answers the handshake without touching the disk. SshNetConnectionFactory
calls FindAsync from inside SSH.NET's synchronous HostKeyReceived event, over
.GetAwaiter().GetResult(), which cannot be avoided; doing SQLite I/O plus an AEAD
open per lookup there would put the handshake behind the cache. So decryption
happens in OpenAsync and RefreshAsync — on unlock and after each sync pass,
exactly where the host and key lists already reload — and FindAsync is a
dictionary read under a lock with no await inside it.

That snapshot is where the one real bug in this change lived. Install originally
merged the live pins over the freshly loaded snapshot, to protect a TrustAsync
that had landed while the read was in flight. It would also have resurrected
every pin the user had just forgotten, and stopped a withdrawal made on another
machine from ever taking effect — the store would have healed the deletion back
into existence on every refresh. Replacing wholesale and discarding the read
instead is correct because writes are the rare case: every write bumps a
generation counter, and a refresh whose stamp is stale throws itself away rather
than winning. Nothing found this but reading the method again; it is the kind of
mistake that passes every test written before it, because the test that catches
it is the one the bug tells you to write.

Forgetting is new, and persistence is what made it mandatory rather than
convenient. A mismatch is a hard refusal with no way to continue — deliberately,
and that stays — so pinning a key permanently is also a way to make a
legitimately rebuilt server permanently unreachable. Before this change the pin
died at exit and the problem solved itself; now it does not.

ForgetAsync drops every algorithm for an endpoint, and it is reachable from the
host editor rather than from the warning. Putting it on the mismatch banner would
have made it two clicks from "this may be an attack" to "connect anyway", which
is the affordance the hard refusal exists to deny. The banner already promised
the key could be removed in the host's settings; that promise is now true and
points at the button.

Trust recorded on another machine becomes visible at the next sync pass, not
immediately, and that is a decision rather than an oversight. The failure it
produces is a first-contact prompt for a host a colleague approved a minute ago:
answerable, and self-correcting on the next pass. The opposite trade — polling
the vault on the handshake thread to close a one-minute window — buys nothing
and costs the property above. The dangerous direction is not reachable at all: a
pin recorded here enters the snapshot as part of recording it, so a refresh can
never discard a local trust decision.

The server learns nothing, and this is the item type where the temptation was
real. A plaintext host column would let a known-hosts screen sort and page
without decrypting anything, and it would hand the operator the map of every
user's estate — assembled, as these things are, out of facts that are each
individually harmless. A host row concedes an address only when relay is
switched on and the database refuses to store one otherwise (ADR 0004); there is
no equivalent excuse here. The table has no column to put one in, and the EF
configuration says so where somebody adding it would be standing.

Two things about the migration in this commit are worth knowing, because both
came out of getting it wrong.

It was hand-written first, including its .Designer.cs, and that version is not
what is here. Verifying it turned up something that had been quietly assumed:
Migration_AppliedCleanly_WithNoPendingModelChanges does not check the model
snapshot. It asserts that migrations applied and that none are pending, which a
wrong snapshot satisfies perfectly — the snapshot only matters as the diff base
for the *next* migrations add, so an incorrect one passes the whole suite and
corrupts the following migration instead. The real check is to generate a
throwaway migration and confirm its Up and Down come out empty. They did, and
the generated designer was byte-identical to the transcribed one across all 1255
lines, so the hand-written work was in fact correct.

Then dotnet ef migrations remove --no-build deleted the wrong migration. With
--no-build the tool reads the previously compiled assembly rather than the files
on disk, and the probe had just changed which migration was last, so it removed
AddKnownHostKeyItem and reverted the snapshot. That turned out to leave exactly
the right diff base, so the migration here is EF's own output rather than a
transcription — a better outcome than the one that was interrupted, arrived at
by accident. Never pass --no-build to migrations remove.

Mutation tested, all three sabotages detected: dropping the algorithm from
KnownHostIdentity.For, merging instead of replacing in Install, and pointing
KnownHostKeyCipher at PortForward — which is what a cast from the wire enum's 10
would silently produce. Each is caught both by an assertion about the mechanism
and by a behavioural test that never mentions it; the resource-type sabotage is
caught by the table from d10a38d and nothing else, which is what that table is
for.

The end-to-end slice now approves the real sshd's host key through the vault,
pushes it, and reads it back on the second simulated machine — including a check
that the server learned no address, and that the second machine answers null for
an algorithm never offered.

845 tests green. Zero warnings, dotnet format clean.

Three things are deliberately not fixed. A tombstone queued over a create that
was never pushed is refused by the server as Invalid and parked; that is
pre-existing for all four item types, and the fix belongs in
VaultItemRepository.DeleteAsync rather than here. Deleting a host, or changing
its address, orphans its pins — both are correct as trust decisions, since a pin
describes an endpoint and not a bookmark, but nothing surfaces the leftovers.
And there is no interface listing pins at all: trust is created at the connect
prompt and withdrawn in the host editor. A known-hosts list is where the orphans
would become visible, and it wants the vault column rework first, for the same
reason the credential editor does.

jaap-jan 70b3290a77 Bind an SSH key to a host instead of picking one per connection
A host now names the key it authenticates with, or none, as a field in its
encrypted payload — so the choice follows the host to every machine rather than
being made again each time somebody connects. The per-connection "Use key"
switch it replaces was a stopgap for not having this, and keeping both would
have left two mechanisms answering one question.

This is the first payload schema version bump, and it does not work the obvious
way. A host is written at the *lowest* schema version that can represent it: one
that binds a key is written at 2, one that does not is still written at 1, byte
for byte as it was before the field existed. The version is what makes an older
client refuse to edit an item, so stamping 2 unconditionally would mean
upgrading a single machine and renaming a single host made that host uneditable
on every machine that had not upgraded yet. Confining the cost to the hosts that
actually use the field is the difference between a team noticing a bump and a
team being blocked by one. HostSecretCodec states the rule so the next field
added follows it, and a test pins the version-1 bytes against a literal rather
than against the codec, because the claim is about history: every host already in
every vault has to re-encode to what it encoded before, or the first sync after
an upgrade would push the whole vault as changed.

A binding is an item id, not a copy of the key — a second copy of a private key
is one that goes stale — which means the reference can dangle when the key is
deleted on another machine. Both places that meets are handled the same way, by
refusing rather than falling back:

- Connecting to a host whose key is gone is refused outright. A host somebody
  deliberately set up for key-only access must not quietly start offering a
  password.
- Opening such a host in the editor keeps the binding, selected, labelled as
  missing. The quieter version of the same failure is someone editing the port
  and saving, silently converting the host to password authentication with
  nothing ever having said so.

Two things this found by being falsified:

- The merge was untested for the new field, and "just take the server's value"
  passed the entire suite — a local binding change would have been discarded with
  no conflict recorded. HostSecretMergeTests already had a test written for
  exactly this class of omission; it simply had not been extended.

- Adding a nullable field exposed a defect in HostSecretMerge.Field: it
  short-circuited when the discarded value was null, so the formatter never ran
  for the one case where null is a value rather than an absence, and a field
  whose absence has a name could not report it. Now the formatter always runs,
  and "no key" appears in the conflict log where an empty string used to.

Also fixes eight nullable warnings in SyncEndpointTests left by the server-side
SSH key commit, which had omitted the null-forgiving operator the rest of that
file uses. They were invisible until an unrelated change forced the project to
recompile.

The end-to-end slice now binds its host to its key, so a schema-version-2
payload goes through the real API, the real PostgreSQL and back out on a second
machine.

745 tests green. Zero warnings, dotnet format clean.

jaap-jan e3fd3e1728 Sync and authenticate with SSH keys on the client
Completes the client half of SSH keys: they sync alongside hosts, appear in
their own list, and can be selected to authenticate a connection instead of
typing a password.

The reconciler and the repository were Host-typed throughout, so the choice was
to generalise them or to keep a second copy per item type. Generalised, because
ItemReconciler's whole premise is that the pull and the push paths must answer
the same collision the same way — two copies would drift the first time one of
them was fixed. What is genuinely per-type now arrives through
IItemKind<TSecret>: the cipher, the merge, the plaintext columns, and the noun
to use when telling a person what happened to their item. Generic where the
server's IItemKind is not, and for the reason that reverses there — the client
needs the concrete type, because it merges field by field.

The pull filter is derived from the same registry that builds the reconcilers.
That is the specific failure being designed out: an item type that encrypts,
merges and lists perfectly and is never once requested from the server, so it
works on the machine that made it and exists nowhere else.

No client cache migration. The item table's primary key and the outbox's unique
index already carry the entity type, and AadResourceTypes already mapped SshKey
— so a host and a key may share an id and never see each other's rows, which
SshKeySyncTests now arranges deliberately.

A key hands the server nothing in plaintext. There is a public_key_fingerprint
column and it would be accepted; leaving it null is deliberate. A fingerprint is
not secret but it is a stable identifier for a key pair, so filling it would let
an operator tell which of their users hold the same key and correlate one across
vaults, for a column nothing reads. The design allows itself one plaintext
concession — the relay address, which the relay cannot work without — and this
is not that.

A key is chosen per connection rather than bound to a host, which works the way
ssh -i does. Binding one needs a field on HostSecret and therefore a payload
schema bump, which makes every host written afterwards read-only on an older
build; worth doing deliberately rather than as a side effect of adding keys.

Three things this found, all of them by being falsified rather than by review:

- Making the reconciler generic silently turned a record comparison into
  reference equality, because == on a type parameter is not value equality. The
  effect would have been a conflict recorded on every pass for an unacknowledged
  create that had in fact landed. Sabotaging the fix left all 73 tests passing —
  nothing covered that branch — so ConflictMatrixTests now has
  AnUnacknowledgedCreateThatDidLand_IsDroppedQuietly, which fails without it.

- A test asserting that a blank passphrase reaches SSH.NET as null was vacuous:
  it exercised the editor, not the credential path, and passed with the guard
  deleted. Resolved by making SshKeySecret.Passphrase normalise an empty string
  to null, so there is one spelling of one state — which also keeps two clients
  from producing different payload bytes for an identical key. That exposed a
  wider gap: SshKeySecret, its codec and its merge had no direct unit tests at
  all. They have 25 now.

- The reason first given for that normalisation was false. It claimed SSH.NET
  rejects a passphrase supplied for an unprotected key; measured against a real
  sshd it ignores it and authenticates anyway. Corrected everywhere it was
  stated and recorded in docs/platform-flags.md. The same test file also closes
  a real hole: SshPrivateKeyCredential had never been exercised against a
  server, because the existing key test builds SSH.NET's auth method directly
  and bypasses the path a vault-held key actually takes.

Only one editor may be open at a time. Both sit in the same 340-pixel column as
Auto rows and their heights together exceed it at the window's minimum size, so
two open editors put the lower one's Save and Cancel past the bottom edge — the
same failure this window already shipped once with the setup screens. Expressed
as a state rule because that is the only form of it this repository can check:
nothing here loads a .axaml. The refusal keeps what was typed, since in the key
editor that is a pasted private key the user may have nowhere else.

The end-to-end slice now carries a key as well as a host, so both item types go
through the real API, the real PostgreSQL and the real crypto in one pass — the
three hand-kept mappings between enums that do not line up are the reason that
is worth doing rather than trusting the unit suites.

735 tests green, including the container-backed SSH and end-to-end suites. Zero
warnings, dotnet format clean.

jaap-jan 5a899afd78 Decide what Lock does to a running shell, and say it
Pressing Lock nulled and disposed the vault view model and touched nothing else.
TerminalWorkspace is injected from App.axaml.cs and outlives every lock, so the SSH
connection, the pty and the pump all kept running while the window said "Unlock your
vault" — and since 0500e43 collapsed the WebView while locked, that live session was
invisible as well as unstopped. CloseSessionAsync was reachable in production only from
DisposeAsync, i.e. shutdown. None of this was written down anywhere, so it was neither a
policy nor a bug, which is the actual problem.

Shells now deliberately outlive the lock, and every layer says so.

The reason to prefer this over making Lock a disconnect: locking is what a person does
when they walk away from the machine, which is exactly when a long upgrade, build or
transfer is most likely to be in flight. Ending every shell would make Lock a button that
destroys work, and the predictable response is to stop pressing it and leave the vault
open instead. The idle auto-lock this will grow decides it outright — an unattended
timeout that killed a running job would be worse than the exposure it removes. Closing
the channel also buys less than it looks: the session was authorised at connect time by a
credential the remote verified itself, and no vault key participates in keeping it alive,
so locking cannot retroactively un-authorise it any more than removing a member can.

Stated honestly rather than implied, because the lock screen is what hides it:

- The unlock screen shows how many shells are still connected, and that locking closes
  the vault and not the connections — so a machine still holding authenticated SSH
  channels does not present itself as merely "locked". Shown only when there is something
  to disclose. Quitting is what ends them, and the text admits that.
- The Lock button carries the same thing in a tooltip, since its name implies the
  opposite of what it does to a shell.
- README lists it as a third architecture consequence beside non-retroactive revocation,
  which is the same shape of honest limit; docs/crypto.md §10 records it as a threat-model
  boundary; TerminalWorkspace and LockAsync carry the argument next to the code.

LiveSessionCount deliberately does not count dictionary entries. Nothing removes a
session when the remote closes the channel by itself — RunSessionAsync only drops the
renderer registration — so sessions.Count would report a shell that exited half an hour
ago as still running, on the one screen where a user is deciding whether it is safe to
walk away. A completed Run task is what "the shell is gone" actually looks like. While
locked the number can only fall, since opening a session needs the vault, so a stale
value over-reports rather than under-reports.

Both new tests fail when the policy is reverted: the count test times out against
sessions.Count, and the shell test reports "workspace.LiveSessionCount should be 1 but was
0" when Lock closes sessions. ShellFlowTests also stops building its workspace with a real
SshNetConnectionFactory that nothing ever called, which had made the suite's independence
from the network a coincidence rather than a property.

Verified by hand with a live shell, which nothing had done: a harness mirroring
MainWindow.axaml's 340,* grid with a real NativeWebView, the shipped WebAssets, a real
sshd in a container, and an ISshShellSession decorator recording every window-change the
remote is actually told about. Across lock and unlock, no window-change reached the remote
at all, stty size answered 50 118 before and after, the renderer's own buffer came back
byte for byte with the wrapped line intact, and the session stayed live throughout. A
control run that never hides the WebView behaves identically, so nothing above is startup
or idle behaviour. Keystrokes injected while locked reach nothing: twelve of twelve
SendInput events accepted with the harness confirmed as the foreground window, no probe
character in the remote's output, and a following Ctrl-U answered BEL, so nothing was
queued in the line editor either. A hidden WS_CHILD window is not eligible for keyboard
focus, which is what makes surviving the lock defensible rather than merely convenient.

Correction to a claim made in f80b3d4: terminal.js's guard comment listed "a host that
hides the WebView while the vault is locked" among the paths that reach a degenerate fit.
It does not. Collapsing the control hides a native child window without resizing it, so
the page still reports paneWidth 840 and paneHeight 760 with unchanged cols and rows, no
ResizeObserver callback fires and the fit never runs. Establishing that rather than
assuming it: the same cycle with MINIMUM_FITTABLE_PIXELS patched to 0 — the guard fully
disabled — is equally clean. The guard is still right for minimising and for a splitter
dragged to the edge; it is simply not what makes locking safe, and must not be cited as
though it were.

Recorded, not fixed:

- Nothing closes one terminal from the interface, so a user reading "1 shell is still
  connected" can only act on it by quitting. CloseSessionAsync is tested and correct;
  VaultViewModel discards the session id it would need.
- A session whose remote exits keeps its ISshConnection, and the thread ShellStream parks,
  until the process ends.
- Suspected and seen once: before the harness waited for the window's scale to settle, a
  DPI settle pushed a 2202x1328 pane for a window 1180 logical units wide and a later
  re-push reflowed the wrapped line. Three later runs at RenderScaling 1.00 never showed
  it, so it is filed as a lead, not a finding.
- WebView2 fails to initialise with CO_E_SERVER_EXEC_FAILURE when the host executable
  sits under a very long path. Cost an hour on the harness; relevant to packaging.

jaap-jan 0500e43e02 Stop the terminal's WebView painting over the setup screens
The shell layered its setup and unlock screens over the terminal, which does
not work: NativeWebView attaches a real Win32 child HWND through
NativeControlHost, and a child window composites above everything its parent
paints regardless of visual-tree z-order. The cards rendered sliced at the
terminal column's left edge; at the window's default width every one of their
buttons fell inside the WebView's rectangle, so the flow could only be
completed by keyboard, and a click in that region handed Win32 focus to
WebView2 so the text boxes silently stopped accepting keystrokes.

The WebView is now collapsed while the vault is not unlocked. The comment
that previously forbade this — hiding it means never realising it — was
wrong: NativeControlHost creates the native attachment on attach to the
visual tree, never consulting layout or visibility, and NativeWebView replays
a Source assigned before its adapter exists. A collapsed WebView still starts
WebView2, loads the page and lets the renderer attach. Confirmed: 35
msedgewebview2 processes with the control collapsed. What the first
connection after unlocking actually depends on is the existing await on
WaitForRendererAsync, since the data plane drops frames when no renderer is
attached.

Also fixes the second visible defect: the default server URL was
https://localhost:7217, the API's *second* launch profile, while the README,
its appsettings and a plain `dotnet run` all use http://localhost:5233 — so
nothing was listening, and an HTTPS client against a plaintext port reports
"The SSL connection could not be established", which reads as a certificate
problem. The default now matches, a missing scheme is rejected by name
instead of parsing as scheme "localhost", and that specific TLS failure now
suggests http://. Both new tests fail when the fixes are reverted.

Corrections to claims I made earlier and should not have:

- docs/platform-flags.md asserted the opposite of the mechanism above and
  cited an established msedgewebview2 connection as verification. That
  observation was taken while the overlay was showing but, because of this
  very bug, the WebView was uncovered and in plain view — so it confirmed
  only that a visible WebView is realised. A process-level check cannot
  verify a rendering claim. The entry was also filed under "Local cache".
- ITerminalHost was documented as the live seam the app plugs into, with a
  stub standing in for headless tests. It has no implementation anywhere and
  no test uses it; the view navigates the control directly. It also counted
  Avalonia.Controls.WebView and NativeWebView as two interchangeable
  backends when they are one component, with the Linux backend backwards.
- The README claimed the shell's whole path was covered by tests. Its state
  machine is; its layout is covered by nothing, and a headless test could
  not have caught this — headless has no native window, so it would have
  rendered correctly and confirmed the wrong belief.

Verified by screenshotting the running app: the card renders complete and
centred at the default size, with the button clickable.

jaap-jan b9e7c258ae Point the design-time factory at the stack the repo ships
`dotnet ef database update --project src/DodoSSH.Infrastructure` — the
command the README documents — failed on a clean machine. The design-time
default named `dodossh_design` as user `postgres` with no password, which is
a database this repository never creates, while the development compose
stack creates `dodossh`/`dodossh`. The failure arrives as a SCRAM
authentication error, so it reads like a broken container rather than a
stale default.

The default is now the compose stack, since that is the only local database
the repo defines. DODOSSH_DESIGN_CONNECTION still overrides it, and a real
deployment migrates through that or the migrator job.

Also documents running the thing end to end, which the README never covered:
the four commands in order, that migrations are a separate step because the
API deliberately fails readiness rather than migrating, and the three M1 gaps
visible in the first five minutes — so they are expected rather than
diagnosed.

jaap-jan 34304b989b Make the end-to-end suite self-contained with Testcontainers
It needed a hand-started stack and an opt-in flag, so it ran on one machine
and never in CI. It now brings up PostgreSQL, Keycloak and an OpenSSH server
itself, applies the committed migrations and starts the API as a child
process, which makes it part of the ordinary test run at ~25s.

The API runs as a process rather than through WebApplicationFactory. The
client builds its own HttpClient for a URL the user typed, so there is no
seam to hand a test handler through without inventing one that exists only
for tests — and a test host would replace the entry point, Kestrel and the
content root, so it would never prove that Program.cs composes or that the
committed appsettings is found and layered in the documented order. Running
out of the API's own output directory is what makes its configuration real.

The suite still consumes what ships: the realm file from deploy/keycloak,
the EF migrations, the API's own appsettings. Only Oidc:Authority is
overridden, because the container's port is assigned at start. Falsified by
reintroducing the wildcard-port redirect URI the realm once had — Keycloak
rejects the authorization request and the suite fails at sign-in, which is
what proves the committed file is the one imported. Skipping the migration
step likewise fails, and the failure names the pending migration.

A fresh Keycloak per run also sidesteps the --import-realm trap: editing the
realm file and rerunning now always tests the edit.

DodoDbContextFactory gains a Create(connectionString) so the fixture and
dotnet ef place the migrations history table in exactly one place. If they
disagreed the API would report every migration pending, which is how the
readiness gate catches it.

jaap-jan 1d262b7ccc Run M1's end-to-end slice, and fix the two bugs it found
The whole vertical slice now runs against a real Keycloak, a real API, a
real PostgreSQL and a real sshd: sign in through the browser flow, enroll
with the identity-provider key binding, unlock, create a host, sync it,
read it back on a second machine, unlock again with no network, accept an
unseen host key, and open an interactive shell. Opt-in, because it needs
the development stack; skipped with a message naming the commands.

It found two bugs on its first run, and both are the same class: two
sides of a stub agreeing with each other about something the
specification never said.

**The API never applied DodoSshJsonContext to its HTTP JSON options.**
Minimal APIs therefore used the framework's web defaults, which write an
enum as a number. Every request DTO carrying one failed to bind against a
client writing the specified string form — which is the entire sync
surface, unreachable from the real client, with a 400 naming only the
parameter. The documented guarantee that request bodies reject unmapped
members was likewise not in effect anywhere.

Nothing caught it because the API tests posted with PostAsJsonAsync's
defaults, so they and the server had independently settled on integers.
Those tests now serialise through the contract, which is the deeper fix:
removing the new configuration fails 13 of them. Copying settings into
options a host owns is itself the hazard the context warns about, so
ApplyTo lives beside the settings it mirrors and ApplyToTests pins the
transformation, including that inserting the resolver leaves the caller's
own in place.

**The realm registered a loopback redirect URI Keycloak rejects.**
`http://127.0.0.1:*/callback` looks more explicit than the RFC 8252 form
and is broken: Keycloak's wildcards are trailing-only, so the `*` parses
as a literal port and every authorization request came back "Invalid
parameter: redirect_uri". Providers ignore the port for loopback hosts,
which is the whole mechanism, so the correct registration is
`http://127.0.0.1/callback` — path pinned, port free. The value the
server advertises through the discovery document said the same wrong
thing and now says the right one.

Two smaller things, both documented in docs/platform-flags.md:

- --import-realm skips a realm that already exists, so editing the realm
  file and restarting Keycloak changes nothing and serves stale
  configuration. The container has to be recreated. The compose comment
  claimed the opposite.
- Keycloak marks its session cookies Secure even over plain HTTP, because
  SameSite=None requires it. A spec-conformant client drops them and the
  login POST answers 400 with no message; browsers complete the flow only
  because they exempt loopback. Harmless for the product, fatal for
  automation, so ScriptedBrowser carries the cookies by hand and says why.

Also: the server enforces a 64 MiB floor on the passphrase KDF, so this
suite cannot use the 8 MiB profile the other client suites take for
speed. Those only get away with it because their in-memory servers have
no policy — worth knowing rather than rediscovering.

638 tests. The solution-wide run stays green with the stack down: exit
code 8 means "no tests ran", which the platform reports as failure, so
the opt-in project ignores exactly that code.

jaap-jan 49f617b450 Wire the Avalonia shell to the vault
The host list now comes from the vault instead of from a form. A fresh
machine takes a server URL, signs in through the browser, enrolls, and
from then on opens with the passphrase alone.

DodoSSH.Client.Session is the composition layer: where a profile lives,
how it unlocks, and how a machine gets one. ClientPaths picks a
non-roaming per-OS directory — %LOCALAPPDATA% and never %APPDATA%,
because a SQLite cache that roams between two machines is a corrupt one,
and each machine's outbox is its own. SessionOpener needs no transport at
all and could not reach one if it wanted to; that is the offline unlock,
asserted rather than asserted about. A wrong passphrase, a stale KDF and a
grant revoked by a rekey are three different answers, because the remedies
are three different things and telling someone to retype a passphrase that
was never the problem is worse than saying nothing.

The shell's states are the onboarding story. The recovery code gets its
own state that cannot be clicked past: it exists for one moment, losing it
with the passphrase loses the vault, and there is no server-side reset by
design. It is dropped from memory on confirmation rather than merely
hidden.

Sign-in is a delegate over IVaultServer, so the whole state machine runs
in a test against an in-memory server — no browser, no identity provider,
no toolkit. The view models are plain observable objects, which is what
makes that possible. What it does not cover is whether the XAML binds to
the right names; that needs a rendered tree and Avalonia.Headless, and is
its own piece of work.

Three things found by doing it rather than by reading it:

- Pooled SQLite connections keep the database file open after the last
  context is disposed. On Windows that means locked, so the application
  could never replace its own cache — and a test could not clean up after
  itself, which is how it surfaced. Dispose now clears the pool.
- EF's SQLite provider puts the database in WAL mode, so the cache is
  three files. A comment in ClientCacheFactory claimed the opposite;
  reading PRAGMA journal_mode off a real launch settled it. WAL is the
  right mode here — a sync pass writes while the interface reads — so the
  comment was wrong on the merits as well as on the fact.
- Enrolling a device key with nowhere to keep the private half would put a
  wrap on the server nobody can open and make the device list claim this
  machine can unlock without a passphrase. Device binding is now optional
  and the shell declines it until the OS keystore is wired.

Verified on Windows: the client created %LOCALAPPDATA%\DodoSSH\cache.db
and migrated it on first launch, and msedgewebview2 held an established
connection to the data plane while the unlock overlay covered it — which
is the point of covering the WebView rather than collapsing it, since a
NativeWebView that is never laid out is never realised.

630 tests, up from 593. The recovery-code gate and the offline unlock were
each verified by breaking them and watching the right test fail.

Still to do for M1's actual definition of done: the manual run against the
real API and a real Keycloak. Credentials are not a synced entity type
yet, so a connection still asks for a password, and the interface says so
rather than implying otherwise.

jaap-jan 8d2416a602 Add the encrypted local cache and the sync client
Three new client projects, and the wire-contract fix they needed.

DodoSSH.Client.Domain holds the decrypted item model and the three-way
merge, with no I/O at all — so the suite that decides whether a
credential can be lost runs in milliseconds with nothing to mock.
Scalars defer to the server on a genuine clash so every replica resolves
the same triple identically and two clients cannot ping-pong; directives
merge per name so two people each adding one both keep theirs; the jump
chain merges as a whole value because its order is the route. Whatever
loses is returned rather than dropped.

DodoSSH.Client.Storage is EF Core on SQLite, no SQLCipher: the rows are
already ciphertext, so an encrypted file would protect protected bytes
at the cost of a native dependency. It keeps the server's state and the
outbox in separate tables, which is what preserves the common ancestor a
merge needs. One pending operation per item, enforced by a unique index.

DodoSSH.Client.Sync is the pull/apply/push loop. Pulling never decrypts
— a change with no local work pending is plumbed as ciphertext — so a
first sync of thousands of items does not run twice as many AEAD
operations for nothing.

Contracts: EncryptedPayload gains WrappedDataKey and DataKeyId. The
specification has required a per-item data key since crypto.md §3, the
columns have existed since the first migration and DshAad.ItemPayload
binds the id, but this record had nowhere to put either — so a
spec-compliant item could not be transmitted at all. Found by writing
the client that has to produce one. Also closes a hole in
AadResourceType, which had no value for the HostTag and HostCredential
that SyncEntityType has always listed.

Four bugs the tests found, not review:

- SQLite refuses to order or compare its own DateTimeOffset mapping, and
  throws at execution rather than model build. Collecting tombstones and
  listing conflicts are both that shape, so this was a crash waiting for
  the first user with a deleted host. Timestamps are integers now, by
  convention so a later field cannot be the one left unconverted.
- SQLitePCLRaw 2.1.11, which EF resolves, is covered by
  GHSA-2m69-gcr7-jv3q. Pinned forward as a family.
- Resurrecting content from a remote deletion cleared the original
  before queueing the copy. Two transactions, so a crash between them
  lost the work; reversed, and the rescued id is derived from the
  tombstone so a replay coalesces instead of duplicating.
- Several equality assertions went through Shouldly's ShouldBe, which
  compares IEnumerable element-wise and so tested nothing about the
  Equals these types exist to provide. Corrected; the falsification that
  caught it went from 2 failures to 6.

The push response's cursor is deliberately ignored. It sits after this
client's own writes, so adopting it skips anything another client
committed at a lower sequence in the window between a pull and a push —
permanently. Re-reading one's own writes is idempotent and costs a page.
The Contracts doc that invited the shortcut now says so.

593 tests, up from 448. The delete-versus-edit rules, the ancestor
retention, the fresh operation id on coalesce and the cursor safeguard
were each verified by breaking them and watching the right test fail.
2026-07-29 10:27:37 +02:00
jaap-jan 5fccd53824 Add the Avalonia app and the xterm renderer, and fix two real bugs
The terminal works end to end. A new integration test drives a real sshd in
a container through a real PTY, the real pump, the real loopback WebSocket
with its token and origin checks, and a ClientWebSocket standing in for the
page: the login banner arrives, typed input round-trips, and `stty size`
reports the 100x30 the session asked for. The only untested link left is
xterm drawing bytes it was handed.

The WebView is de-risked on Windows, which was the plan's largest risk. Not
by assertion: with the app running there is an established TCP connection
from msedgewebview2 to the data plane port, so WebView2 launched, navigated
to the loopback page, executed terminal.js, and completed the WebSocket
handshake against the real token and origin checks. Linux remains unproven
and the package's own release notes now corroborate the concern -- Linux uses
a WPE backend, and it ships a NativeWebDialog described as useful where
embedded WebViews may be unavailable.

Two bugs found by building it, both of which would have shipped:

- ShellStream.Write buffers and needs an explicit Flush. Without one a
  keystroke is accepted, reported as written, and never reaches the remote:
  the terminal displays output perfectly and simply stops responding to
  input. SSH.NET's own WriteLine flushes, which is why the earlier spike
  never hit it. Found by isolating the pump against real SSH and reading
  BytesRead=51 -- banner and prompt through, nothing after.
- The Windows app manifest needs a supportedOS list, or Avalonia's native
  control host fails outright and the terminal never starts.

Also fixed a genuinely flaky test I happened to catch: SyncCursorTests
tampered with the *last* base64url character, whose low bits the decoder
ignores when the input length is not a multiple of three -- so a tampered
cursor sometimes decoded to identical bytes and verified. It failed roughly
one run in thirty, depending on a random key. Now tampers the penultimate
character, which is fully significant at every length; 40 consecutive runs
are clean.

xterm 6.0.0 plus the fit and webgl addons are vendored as UMD bundles rather
than built with npm, so a clean clone needs only the .NET SDK. Provenance
and licences are recorded next to them, along with the UMD global names
terminal.js depends on -- a bundle that switched to ES modules would load
without error and leave Terminal undefined.

The renderer acknowledges output from term.write's completion callback, not
on receipt. Acknowledging early would return flow-control credit for bytes
the screen has not caught up with, which is the one thing the credit window
exists to measure.

TerminalWorkspace moved into DodoSSH.Client.Terminal: it has no Avalonia
dependency, and having it there is what let the end-to-end test exist at all.

404 tests pass, zero warnings on a clean rebuild, format clean.
2026-07-28 22:30:42 +02:00
jaap-jan 885fb17bdc Clear the SSH gate: window-change reaches the remote, and licence as MIT
Licence is MIT, set solution-wide rather than only on the packable project:
DodoSSH.Contracts is published so clients can build against it, and a
package with no licence expression is one a corporate policy scanner
rejects outright.

The SSH.NET spike is the M1 client gate and it passes. SSH.NET 2025.1.0
exposes ShellStream.ChangeWindowSize, but a method existing is not the
remote observing it, so the tests read `stty size` back from a real sshd
after resizing rather than asserting the call did not throw. Repeated
resizes each take effect too, which matters because dragging a window edge
produces a stream of them. The IChannelSession fallback is not needed.

Also verified against a real sshd: password and public-key auth, that the
host key arrives as a raw blob we can fingerprint ourselves rather than
reading SSH.NET's MD5 property, and that refusing the key via CanTrust
actually aborts the connection -- without which the TOFU dialog would be
decoration.

Kept as a permanent suite, not deleted after the spike. An upgrade that
silently stopped sending the request would present as wrapped output only
after a resize, which is easy to misattribute to the terminal emulator.

Two bugs in the test itself, both worth naming because either would have
been read as "resize does not work":

- A PTY emits CRLF, and the anchored regex rejected the CR. The output
  visibly contained `24 80` while the match failed.
- Each read can begin with output still buffered from the previous command,
  including its size line. Taking the first match would have reported the
  pre-resize size.

platform-flags.md now records window-change as resolved rather than
unverified -- a stale flag is worse than none -- plus the three real SSH.NET
limits found on the way: ShellStream does not override ReadAsync so every
idle session parks a pool thread, one connection cannot serve both
SshClient and SftpClient, and agent forwarding needs an upstream change.
2026-07-28 16:52:09 +02:00
jaap-jan b7325b78ca Record the platform flags that were only in conversation
ci / build and test (ubuntu) (push) Has been cancelled
ci / build (windows) (push) Has been cancelled
Development and testing are Windows-only, so anything unverified elsewhere
needs to be written down or it gets assumed to work. Several of these have
already cost time once: PostgreSQL 18 moving its data directory silently
gives a carried-over compose file an empty volume, and a loopback-bound
Tomcat beat Docker's 0.0.0.0 publish for `localhost`, making every Keycloak
realm 404 while the container looked healthy.

The largest entry is the Avalonia WebView on Linux, which remains the
biggest risk in the plan and is why the terminal sits behind ITerminalHost.

Also records two things this milestone deliberately left undone -- no rate
limiting on the enrollment and sync write paths until M2, and /me not
touching last_seen_at_utc -- so neither reads later as an oversight.
2026-07-28 16:08:04 +02:00
jaap-jan a628762cd1 Add /me and enrollment with the identity-provider key binding (M1)
The last backend piece of M1. A client can now log in, discover it must
enroll, publish its identity key, and get a usable personal vault.

Enrollment is one indivisible act. One transaction writes the key, its
wraps, the device, the key log entry, the vault and the vault key grant,
because none of them is useful alone: a key with no vault leaves a user
unable to store anything, and a vault with no grant is a container nobody
can ever open -- including its owner, since only the client can wrap the
key and it has already moved on.

Two independent checks run, and neither substitutes for the other. The
Ed25519 self-signature proves possession of the private key. The
identity-provider binding proves whose key it is: the client hashed its
statement, used the hash as an OIDC nonce, and the resulting ID token is
the provider's signature over exactly those public keys. This server
cannot mint that signature, so it cannot invent a key for a user who never
enrolled -- which is the attack that would otherwise let an operator read
every vault by publishing its own key as yours.

The binding token is stored verbatim, not just summarised. Clients must
repeat the check against the provider's JWKS fetched directly, and storing
only our conclusion would ask them to trust the server about the one
question the design exists to avoid trusting it about.

Key log appends take a deployment-wide advisory lock. The falsification
matters more than the passing test: with the lock removed,
Enroll_ConcurrentEnrollmentsByDifferentUsers_LeaveAnUnbrokenChain fails
with entry 11 linked to the wrong predecessor. Different users trip no
unique index, so without serialising they all read the same head and the
chain forks -- indistinguishable from the key substitution the log exists
to make detectable, and permanent, because the log is append-only.

Enrollment is idempotent. Vault ids and keys are client-chosen, so a
client whose response was lost re-sends the identical body and gets the
identical result. Without that, a lost response leaves a user enrolled
against a vault they never learned the id of.

Contract change, breaking the v0.1 freeze deliberately. EnrollmentRequest
had DevicePublicKey but no wrap to go with it, which is unsatisfiable:
only the holder of the secret bundle can seal it, so the server could
never fill the gap. Added DeviceWrappedPrivateKey, and PersonalVault so
enrollment can be atomic rather than leaving an unopenable vault behind
two endpoints that do not exist yet. No client exists and no package is
published, which is exactly when PublicAPI.Unshipped.txt expects this.

Sync now requires the Enrolled policy, which until now was a stub whose
name promised a check it never made. The sync denial tests use enrolled
intruders instead of unenrolled ones -- an unenrolled caller is stopped
before the vault check runs, which would have left those tests passing
without exercising the thing they exist to prove.

Also fixed: omitting kdfParameters from the JSON body was a 500. A
record's non-nullable parameters are a compile-time promise, not a runtime
one.

268 tests pass, zero warnings on a clean rebuild, format clean.
2026-07-28 16:06:35 +02:00
jaap-jan ce43f397a6 Add ADRs 0001-0006 and README (M0)
Records the decisions the milestone plan already made, with their costs stated rather
than only their benefits:

- 0001 e2ee-trust-model: key hierarchy, the AAD-to-row binding that stops the server
  moving ciphertext between rows, and the four-layer public-key trust story. States
  plainly that revocation is not retroactive, that Connect cannot be a security
  boundary, and that the IdP becomes a key-distribution trust root.
- 0002 minimal-apis: feature modules with explicit registration; capability negotiation
  instead of Asp.Versioning, since client and server upgrade independently when
  self-hosted.
- 0003 sync-protocol: single write path, revision cursors, and the bigserial
  pre-commit sequence gap that silently corrupts sync — plus the per-vault advisory
  lock that fixes it and the test that must prove it.
- 0004 relay-authorization: relay forwards bytes rather than terminating SSH, so
  zero-knowledge survives; server-resolved target IPs in the ticket to defeat DNS
  rebinding; why host addresses must be plaintext when relay is enabled.
- 0005 no-application-layer: why the usual Application/mediator layer earns nothing
  here, with the trigger that would make us revisit it.
- 0006 observability-stack: OTel plus built-in ILogger; liveness excludes dependencies
  so a database blip cannot restart the container and kill live SSH sessions.

Also adds a README covering layout, build, enforced conventions and milestones.
