Import a Hetzner Cloud project's servers, and forget the token that read it
An estate on Hetzner is already described somewhere: the project lists every server, its addresses, its plan and where it runs. Getting that into a keychain meant copying forty addresses out of a browser by hand, which is the same work the ssh_config importer exists to remove for the machines described in a file. ◆ A WIZARD RATHER THAN A SCREEN, AND THE DIFFERENCE IS WHAT EACH STEP COSTS. ImportScreen reads a file that is already on this machine, so it scans on open and shows a list. This cannot: it needs a credential that has to be made in another company's console first, and then it makes a request over the internet. Those are two moments rather than one, and a screen that mixed the token box in with the list would ask for the credential again every time somebody came back to look at the list. So three steps — token, choose, done — and the first two write nothing. Step two carries one address choice, one login user and one port for the whole import, because an estate is reached the same way throughout and a per-server dropdown would be forty answers to one question. ◆ THE TOKEN IS USED ONCE AND CLEARED, INCLUDING WHEN IT WORKED. The half worth stating is the success path. Clearing only on failure would leave a credential capable of listing somebody's whole estate sitting in a text box for as long as they spend reading forty rows, which is the longest anybody stands on this screen. Nothing writes it to the vault, to settings or to a log, and reopening the wizard restarts at step one rather than resuming — a resumed step two would be a list nothing on screen has the means to refresh, going on looking current for as long as the application stays open. Read is the only permission it needs and the note above the box says so: a Read & Write token would work identically here and would be a credential capable of deleting the estate, pasted in for no gain. The note also says a token belongs to one project — there is no API call that will say which, and none that lists the others — so an account with four projects runs this four times. Without that sentence the wizard looks like it lost most of the estate. ◆ THE ADDRESS IS A CHOICE, AND TWO OF THE THREE FALL BACK WHERE THE THIRD MUST NOT. Public IPv4 and public IPv6 fall back to each other: the same machine over the same internet, so the worst case is a route nobody picked, and the row says which. Private does not fall back at all. A server on no private network is simply not importable under that choice — its tickbox is disabled, and neither direction of the header's tick-all can reach it — because falling back would put an address on the open internet into a bookmark that was asked to stay off it. IPv6 needs saying twice over. Hetzner routes a whole /64 and the API reports the network, which nothing can dial; the address a stock image answers on is the first one in it. That is a convention of Hetzner's own images rather than a fact the API stated, so every use of it carries a warning on the row and in the stored note, and it is computed by setting the low byte rather than by string surgery on the prefix. It is not an edge case either — IPv4 is billed separately now and a project built since then can be entirely IPv6-only. ◆ NOTHING IMPORTED HERE AUTHENTICATES, AND THAT IS SAID BEFORE THE BUTTON. Hetzner has never held the private half of an SSH key. The API will name a project's keys and hand over their public halves; there is no private half to bring. So every host arrives bound to nothing and asks for a password until somebody points it at a key already in the keychain — the same shape an ssh_config import has with its key tick off, and stated above the button on the same reasoning: somebody who is not told will conclude the import was broken. What the note keeps is what does not go stale — the id, the plan, the location, the image, the labels. The power state is a column and never a note: "running" about a machine somebody switched off last March is worse than no note. ◆ WHERE IT LIVES: TWO FLAGS OVER ONE CONTENT COLUMN. Drawn over the Preferences page inside settings mode exactly as ImportScreen is, with SettingsNav unmoved and the titlebar offering "Back to preferences". IsHetznerImportOpen is a second flag rather than a "which importer" enum, because they are two independent facts about the content column and a single value would need a "neither" member IsImportOpen already expresses; what keeps them from both being true is that every path that opens one closes the other. The titlebar and the Preferences page ask IsImporterOpen, which is written against both. Preferences grows a second importer row beside the first rather than one row that asks "from where?", which would put a question in front of the far more common answer. ◆ WHAT IS NOT HERE. Hetzner's Robot — dedicated servers and Storage Boxes — is a different API behind a different credential, and nothing in this touches it. Said on the Preferences row and on the token step rather than left to be discovered by an account that has both. And there is no phone layout. This one would work on Android, unlike the ssh_config importer beside it: it is a token and a network request, the view model is shared already, and scoped storage has nothing to do with it. What is missing is a screen — the desktop draws a five-column table, and the phone version of that is a different layout rather than the same one narrower. Recorded in android-port.md and on the phone's own Preferences screen, because the note there previously read as though no import of any kind could work. ◆ TESTS, AND WHAT IS LEFT FOR A PERSON. HetznerCloudClientTests is 16 cases over the shapes the API actually returns, against a stubbed HttpMessageHandler: paging followed, the token in a header and never a query string, a refused token distinguished from a fault at Hetzner's end, a token with a line break refused before anything is sent, the /64, the private-network asymmetry, and a server the API described without a name. ShellFlowTests.Hetzner.cs is 11 more against this fixture's real vault, real cache and real server — split into a file of its own, as FakeVaultServer keeps its team endpoints. What they establish beyond the reader's own suite is the half it cannot reach: that reading stores nothing, that importing goes through the ordinary create-and-push path and lands on the server with nothing pressing Sync, that a server the keychain already has arrives unticked, and that the token does not outlive the request. Two layout cases measure both steps against the same content budget every other settings page gets, which is also what proves the markup binds to names that exist. Manual checks 2.11a–2.11d are what no test in this repository can do, because there is no account, no token and no network in the ordinary suite: a real project listed against the real console, a wrong token, the private choice, and what an imported host does when you connect to it.

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. |
