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

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

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

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

Verified on screen on Windows 11.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

---- WHAT PROVES IT ----

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

jaap-jan 8707629a6c Make the vault the thing you share, and ask a host which one it lives in
The teams screen listed teams that owned vaults, so sharing four servers with two
colleagues meant creating a team, then a vault inside it, then wrapping a key.
Two of those three steps are about a concept nobody arrives wanting. The screen
now lists vaults: naming one creates the membership list that carries it, named
after the vault and owned by you, and members, invitations, roles, hand-over and
key holders all hang off the vault they apply to.

Nothing on the server moved. VaultAccessService still resolves a shared vault
through team_membership and every membership call still names a team id — what
went is the requirement that anybody make one. The split the whole design rests
on is untouched and is still what the screen is built around: adding somebody
authorises the server to serve them, and only a machine holding the key can make
the vault readable. ADR 0009 keeps its decision and gains an addendum recording
which half of it a person is now asked about.

The one place the team resurfaces is a membership list carrying several vaults,
which this screen cannot produce and does not hide: the members section says so,
because "adding somebody here adds them there" is precisely the fact a
vault-shaped screen is in a position to conceal.

Two things left the interface and one arrived. Creating a team is gone, and so is
archiving one — it was only ever possible for a team owning no vaults, and a
screen whose rows are vaults has no row for one, so the button would have been
unreachable or always refused. The endpoint is unchanged and the screen states
the limit instead, since a vault cannot be deleted at all. The exception is a
create whose second call failed: cancelling that form archives the membership
list it left behind, which is a deliberate departure from this client's rule
against tidying up on the user's behalf, made because nothing else can reach it.

What arrived is PUT /api/v1/vaults/{id}. Without it the screen loses its only
editing action, since renaming the team behind a vault is invisible to everybody
who was never shown the team. It is gated on PermissionFlags.Admin — the line
UpdateTeamEndpoint already draws, because a name is what everybody in the vault
sees it called rather than part of its contents — and it renames the owning team
with it when that team carries nothing else, so the row an operator reads and the
name a user says cannot drift apart. The slug never moves, for the reason it does
not move on a team rename. The session edits its cached vault row rather than
replacing it with the response, which deliberately carries no wrapped key.

The host editor now asks which vault a host goes into, beside the name, while
adding and only where there is more than one vault to write to. It is a second
picker rather than the keychain screen's reused, and the two selections are
separate on purpose: that one is a standing preference about where new items go,
this is a field of the host in front of you, and binding both to one selection
would mean a click on the other screen could move a half-typed host. An existing
host is not offered it at all rather than offered it disabled — the two vaults
are encrypted under different keys, so moving an item is a delete and a retype.

That forced a fix worth naming. The group picker was built from the active
vault's groups whatever vault the host was being filed into, so a host put in a
shared vault could be filed under a group only its author can resolve — a
colleague would see it filed under nothing, which is the quietest kind of wrong.
Groups are now kept per vault and the picker follows the vault choice.

Two renames, because the pair they would otherwise have made is a bug farm:
ShellScreen.Vault became Keychain and VaultScreen became KeychainScreen, which is
what the rail has always labelled that screen, leaving Vault for one vault's
contents and Vaults for the vaults themselves. The enum values are unchanged;
NavRail.axaml writes them as x:Static literals.

1536 tests pass, seven more than before. Five are new on the server — the rename
endpoint's success, the team it does and does not take with it, the two refusals
and the empty name — and the client suite gains six and folds four together,
having lost the two about archiving a team.

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

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

Desktop suites green at 155 and 64.

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

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

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

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

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

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 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.

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

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