Let the desktop client replace itself, and give the repository one version
Packaging for Windows, and the updater that only exists once something is
packaged. Velopack, win-x64, fed from the project's own forge — never from the
deployment a client signs in to, which is ADR 0011 rule 2 carried over
unchanged and is why the feed address is a constant in the code rather than a
setting. See docs/adr/0012-desktop-distribution-and-updates.md.
**Nothing is ever installed while somebody is using it.** A newer build is found
on a six-hourly pass, downloaded in the background, and then waits — for a
restart the user presses, or for the next launch they were going to do anyway.
That is a policy rather than caution: this application argues at length that
locking keeps shells running, because a lock that destroyed work would stop
being used, and a restart does not keep them. Having taught that, it owes the
user the choice at the one moment it stops being true, and the sentence saying
so counts the shells it would close.
**The version is now derived from the v* tag**, by MinVer, for everything. There
was no version before this — no property anywhere, so every assembly reported
the SDK's 1.0.0 and the API served that string as its serverVersion to every
client that asked. The tag was already the version of record for the container
image; this makes it the version of record full stop. MinVer's failure mode is
answering plausibly rather than failing, and here a wrong version is a client
that never updates, so it is guarded twice: fetch-depth 0 on every checkout, and
a step that fails a tag build when the tag and the computed version disagree.
**The pack id is DodoSSH.Desktop and not DodoSSH**, which is the one decision
here that would have destroyed data. Velopack installs to %LOCALAPPDATA%\<packId>
and removes that whole directory on uninstall, and %LOCALAPPDATA%\DodoSSH is
where ClientPaths keeps the encrypted cache, the outbox of changes not yet
pushed, and the device key. The obvious id would have had the uninstaller
silently delete work the server has never seen — the thing the application
refuses to do without a counted confirmation. Velopack's own advice to move user
data to roaming %APPDATA% is declined for the reason ClientPaths already gives.
**Releases are cut by a person, and CI gains no job that could.** The tempting
argument is that a forge write token is not a signing key. It does not survive
contact with what the token does: Velopack clients trust their feed and do not
verify a package signature when they apply one, so whoever can write a release
can ship an update every install runs. That is the capability ADR 0011 rule 1
puts on a machine which is not a runner, reached through a different door. The
mechanical objection — vpk needs Windows and the runners are Linux — is the
smaller of the two and is recorded beside it, because somebody will fix one and
believe they are done.
Unsigned for now, deliberately and with the cost stated where a user reads it:
SmartScreen warns once per person, on Setup.exe, because Mark-of-the-Web is
applied by the browser that downloaded it. In-app updates are fetched by the
application and applied from a local file, and never trip it.
The banner is a fourth row of the window rather than an overlay. Anything drawn
in the terminal's rectangle is sliced by the native child window that composites
above it — the defect this window has shipped once — and a sibling row is the
arrangement TitleBar and StatusBar already prove works.
----
Three defects surfaced on the way, none of them in the feature being built.
**A settings key absent from the file came back as the CLR default, not the
declared one.** The JSON source generator builds a record through a synthesised
parameterised constructor and assigns every property from its argument array, so
a property initializer runs and is then overwritten by a default for anything the
file did not contain. A settings.json of {} read back a font size of 0, clamped
up to the 8px floor rather than the 13px the renderer draws at. It could not bite
while there was one setting, because that setting was written on every save and
so was never absent; adding a second would have turned automatic update checks
off for every existing profile, silently, the opposite of the documented default.
Reflection-based deserialisation of the same JSON answers correctly, which is why
every way of checking it by hand agrees except the one that ships. The defaults
now live on the constructor parameters, which is the only place the generator
reads them from.
**Declaring a RuntimeIdentifier on the desktop head broke the server's image
build.** It is the obvious way to let a self-contained publish restore under
locked mode, and it writes a net10.0/win-x64 target into the lock file of every
project the head references transitively — including DodoSSH.Contracts and
DodoSSH.Crypto, which the API builds too. The Dockerfile restores those with no
RID and fails NU1004. Found by running docker build rather than by reading. The
RID stays out of the committed state; the two commands that need one ask for it
unlocked, and the release script puts the lock files back.
**A Docker ARG named VERSION silently sets MSBuild's Version.** An ARG is an
environment variable for the rest of the stage, MSBuild reads environment
variables as properties, and property names are case-insensitive. With the
workflow passing main-<short sha> on a main build the publish died with
NETSDK1018 pointing at DodoSSH.Contracts, a project nobody had touched. The build
stage's argument is ASSEMBLY_VERSION now, empty except on a tag build.
All three are in docs/platform-flags.md, which is where the next person will look.
----
Verified: the whole solution builds and restores locked; 289 shell, 93 layout and
54 session tests pass, including the regression test for the settings defect and
a measurement of the banner at the window's minimum width. vpk pack runs end to
end and reports "Verified VelopackApp.Run()" against Program.Main. The API image
builds correctly both as a main build and as a tag build, carrying 1.0.0 and
0.1.0 respectively.
Not verified, and it needs a published release to be: installing, updating and
uninstalling on a real machine. That is Phase 15 of docs/manual-checks.md, and
the pack id and the WebView2 profile fix are reasoned and commented but only
proved by walking it. Two things to watch at the first upload — the reverse
proxy's body-size limit for a 64 MB asset, and whether vpk upload gitea is happy
with Gitea 1.27.1.

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. |

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.

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. |

Stay signed in, come back online by itself, and let a machine be given up
Three things a machine that has been set up could not do. Unlock now takes Enter, which is the gesture everybody makes after typing a password and which did nothing until they found the button. Signing in survives a relaunch. The refresh token is kept in the local cache, sealed under the vault's own cache key, so a later launch resumes the session through the refresh grant with no browser and nobody present — and because it is sealed under that key, only an unlocked vault can resume it. A locked client therefore cannot reach the server at all, which is a consequence worth stating rather than working around; docs/crypto.md §3.2 records it. Every sync pass asks the shell for a connection rather than reading one captured at unlock, so a laptop that unlocked on a train is online within a minute of finding a network, with nothing pressed. Unlocking itself still never waits on a socket. Signing out empties this machine: the profile, the cached items, the outbox and this machine's device key, with the account's row withdrawn when the server can be reached. It asks first and says what it costs — the outbox count when the vault is open, an admission that it cannot be counted when it is not, and the shells that keep running either way. The vault is on the server and is untouched, which is what makes the same button the only honest answer to a forgotten passphrase, so it is on the unlock screen as well as in preferences. It cannot end the session at the identity provider, and says so. Two defects surfaced on the way. The synchronisation pass that runs when the vault opens never ran at all: the loop is started from inside the unlock command, so the busy flag it yields to was raised by that command — the first sync was a minute late on every launch. And signing in from preferences while unlocked threw an unlock screen over an open vault whose keys were still in memory. The unlock card and the new confirmation live in their own controls because MainWindow cannot be laid out headless, so markup left inside it is markup no test can measure; both are now measured at the window's minimum size in the shapes that grow. What is still unverified is the composed window itself. |

Give hosts and terminals their own screen, and the rest of the vault another
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. |

Measure the vault column instead of arguing about it
Nothing in this repository loaded a .axaml, so the one class of defect this window has actually shipped — a control arranged past the edge of its container, where it cannot be clicked — was the one class nothing could catch. The setup screens rendered sliced once, with their buttons unreachable. The vault column is the next candidate: 340 pixels wide, two lists and two editors, and the only thing keeping it from clipping its own Save button at the window's 520-pixel minimum is a state rule that one editor may be open at a time. That rule was added on the strength of an argument. This adds an Avalonia.Headless project that lays real XAML out at a real size and reports what a user could not reach, and the argument is now a number: with both editors open the column overflows, so the rule is load-bearing rather than defensive. BothEditorsAtOnce_DoNotFit_WhichIsWhyTheRuleExists is the test, and it says what to do if it ever starts passing — the column has room, so delete the rule, not the test. Two findings arrived by measuring rather than by reasoning, and the first one changed the design. MainWindow cannot be shown headlessly at all. Showing it attaches the terminal's NativeWebView, whose Win32 adapter initialises WebView2 on attach, and WebView2 refuses a non-STA thread — which is exactly why Program.Main carries [STAThread] and is written down in that comment. A HeadlessUnitTestSession owns its dispatcher thread and offers no apartment choice, so the whole window is out of reach at any size. That is pinned as a test asserting RPC_E_CHANGED_MODE by HResult rather than by message, so a future Avalonia that makes the adapter lazy will fail it and the harness can be widened. So the column had to become its own control to be measurable, which is the extraction the type-selector rework wanted anyway. Keyboard release moved with it: MainWindow used to call Focus() on HostList by name, and now asks VaultColumn.KeyboardTarget. The window decides that the keyboard should leave the terminal and the column decides where it lands — which is the seam the rework needs, because once the column shows one list at a time, "which list owns the keyboard" is a question only the column can answer. The second finding is the way this kind of test lies quietly. The hint class lived in MainWindow.Styles and carries TextWrapping. A Window's styles reach its whole tree, so nothing about the application depended on where it lived — but a control laid out on its own loses them, and every hint paragraph would have measured as a single line. The harness would have passed while measuring heights that were all too small. The three shared classes now live in App.axaml, which changes no rendering and makes the measurement honest. The detector is calibrated in both directions, because a clipping detector that never fires reads as a guarantee: a deliberately clipped Save button is caught by name, and a list longer than its viewport is exempt. Scrolling is how a list is supposed to handle more rows than fit, and without that exemption the host list would fail the moment it had content. It also mis-fired once and the rule is narrower for it — an empty ListBox is zero pixels tall and correct, so "arranged with no size" now applies only to controls the theme gives a height to. Skia rather than the headless drawing stub, deliberately. The stub's font manager invents glyph metrics, and text height is an input to every stacked panel in this column, so measuring against it would produce numbers that are self-consistent and unrelated to the application. A separate test project rather than more tests in DodoSSH.Client.App.Tests. Avalonia's application, dispatcher and platform are process-global singletons initialised once, and that project's identity is the shell's state machine without Avalonia — the whole reason sign-in is a delegate. The fakes needed to reach a real unlocked vault are shared from DodoSSH.Client.Session.Tests by source link: a project reference would make one test project a library of another, and a copy would be a third implementation of the same decision table drifting from the other two. 855 tests green, 10 of them new. Zero warnings, dotnet format clean. Not done, and this is groundwork rather than the item itself: the type selector. The column still holds both lists at once, so a third item type would still recreate the defect the one-editor rule works around. What is different is that the rework can now be checked instead of eyeballed — including the claim it is being made for, that one editor at a time stops being a runtime rule and becomes a fact about what is in the visual tree. What this harness will never catch is the terminal's native child window compositing over Avalonia content. That is a Win32 property of a real window, no headless surface reproduces it, and it is the reason the WebView is collapsed rather than covered. |
