Let the recovery code be copied, and give the phone a clipboard to copy to
Both screens had made the code selectable and both said why: a person who cannot get it out of the box photographs the screen, and a screenshot is a worse home for it than a clipboard. This finishes that argument. Selecting 64 characters of letter-spaced monospace with a thumb is the version of "possible" people give up on halfway — and on the phone the screen blocks screenshots, so the honest remaining options were retyping it or losing it. It is the one secret this application deliberately offers to a clipboard, and the contrast with the keychain's copy is the whole argument rather than an inconsistency. There, copying the private half is refused outright, because installing a key means pasting the public one and the private one has no business leaving the vault. Here there is no better route: the code exists for one screen, is stored nowhere, and has to reach a password manager. The clipboard is the intended destination rather than a way round the design. The sentence afterwards matters as much as the copy, and is asserted: a clipboard is a staging post, this screen is the only place the code exists, and the next thing copied replaces it. Somebody who copies and does nothing has not saved it. The phone had no clipboard delegate at all — the desktop passed one and this head passed null — so COPY PUBLIC KEY on the keychain answered "this machine has no clipboard" on a device that plainly has one. Nothing about that was platform shaped: Android has a clipboard and Avalonia surfaces it through the same TopLevel. Wiring it fixes that copy too. The test fixture built its shell without a clipboard, which modelled the bug rather than the product, so it has one now and the public-key test asserts what lands there instead of the refusal. The refusal keeps its own test, on a shell built without one, because the view model reads the delegate's absence rather than an empty result — and because a button that silently does nothing on this screen is worse than one that refuses. |

Let the phone replace itself, and give CI a channel it may sign
The Android head had no updater and no release path, and the two are one problem: Android refuses an update signed by a different key, and CI generates a fresh debug key in every container. An APK released from a workflow could be installed once and never updated again — each new one an uninstall, which on this product means losing the cache, the outbox and the device key. So there are two channels, and they are two applications because the platform gives no third option. dev.dodotech.dodossh is cut from a v* tag by a person running scripts/release-android.ps1 with the key ADR 0011 rule 1 keeps off runners. dev.dodotech.dodossh.nightly is cut from main by CI and signed with a keystore committed here in the open — a key everybody has cannot be stolen and grants nothing by being held, which is why putting it in CI does not touch the rule. Neither can update the other, by construction. See ADR 0014. The android job assumed an image with a JDK and an Android SDK on it, which is what a GitHub runner is and what this project's is not. It now installs a JDK, fetches Google's command-line tools, accepts the licences and installs API 36 — each a no-op where it is already satisfied, and each cached by the persistent runner's own disk rather than by an action that would move a quarter of a gigabyte to rebuild a directory that never left. The client reads a small JSON manifest beside the APK, the counterpart of releases.win.json, and compares Android's versionCode rather than a version name: that integer is what the platform itself uses to accept or refuse an install, so comparing anything else would offer updates the phone then rejects. It fetches, and then asks Android to ask — the system draws its own confirmation, and from API 26 will not draw even that until unknown sources is on for this application. IUpdateChannel gained ApplyingEndsTheProcess. On Windows applying replaces the files and restarts, so the shell disposes the vault first and that is what zeroes the keys. On the phone the install is a request and the answer may be no, so disposing first would answer "not now" with a locked keychain and every shell closed — a punishment for declining an update. Two measured bugs found on the way, both older than this work and both invisible to a -getProperty check. ApplicationDisplayVersion is read by the Android targets in a top-level PropertyGroup, so the target setting it from MinVer ran after the only thing that reads it: every APK ever built here said versionName 1.0.0. And nothing found so far varies the launcher name per channel — four mechanisms tried, all of them recorded in platform-flags, none of them reaching the label the launcher shows. The two channels share an icon name for now and are told apart by package name, version, and what the preferences screen says. |

Give the phone both pickers, and settle who signs the APK
The files screen could browse a remote and delete on it, and that was all: there is no browsable local filesystem on Android for a second pane to show, so the gesture the desktop is built around — choose on the left, press the arrow — has nothing to stand on. What replaces it is the platform's own two pickers. ADD FILES is ACTION_OPEN_DOCUMENT, so a document is pointed at wherever it lives and goes to the directory showing; SAVE FILE is ACTION_CREATE_DOCUMENT for the selected row. Both stage through the application's cache, and that copy is a requirement rather than a shortcut. android-port.md predicted a picked document would be a third IRemoteFileStore beside SFTP and S3; it cannot be. FileTransferQueue seeks, because an upload resumes from the byte the last attempt reached, and a content:// URI has no path behind it, no length worth trusting, no promised seek and no grant that survives the document being edited underneath it. Copying first costs one class in the head and nothing at all in the shared layers, where the alternative was every resume rule rewritten around a stream that cannot rewind. The copy is deleted when the transfer completes, kept while it is stopped so RESUME still has something to read, and swept at the next launch — which is the one moment emptying that directory is provably safe, since nothing has queued anything yet. Coming out had a decision going in did not: when to ask where it goes. The save picker is raised before the transfer, so the download runs into the same staging directory and hands its bytes to a callback the head supplied, held against the transfer id so a RETRY still lands where the person pointed. Asking afterwards would put the picker minutes from the button that caused it and, on a phone, usually while the application is backgrounded and Android will not show one at all. The cost is that the picker creates its file when it is dismissed, so a download that then fails leaves an empty one there; that is said on the screen, in the README and in the manual checks rather than left to be discovered. A delivery that fails keeps the staged bytes for the sweep instead of throwing away the one copy of something just fetched over somebody's network. The foreground service counts transfers now, which is the half of it that matters most here: a shell survives backgrounding because somebody is looking at it, and an upload has to survive precisely when nobody is. Queued counts as active, so putting five files in and locking the phone moves five files. The seam was built for this and wired to () => 0 because nothing could fill the queue. Alongside it, ADR 0010 answers the second question android-port.md left open, and it had to be answered before the first release rather than at upload time: a new Play app must use App Bundles and therefore Play App Signing, and an installed app can only be updated by a package signed with the same key, so the first release picks an identity for good. The project holds the key, offline and never in CI — the workflow's package step now says so where somebody would break it — and a DodoSSH deployment never serves the client, because a download link on your own server hands the binary that holds the plaintext to the party the whole threat model is about. The README's M1 gap note was stale in both halves and is replaced by what is actually true: credentials have an editor and a REMEMBER tick, and the device key registers into the TPM under a CNG policy that makes the consent dialog a condition of using it. What is left is the floor rather than a gap — no TPM, or no Windows, means the passphrase on every launch. |

Give the phone a way to enrol the fingerprint it already unlocks with
The Android device key store, the biometric gate and the lock screen's UNLOCK WITH FINGERPRINT button have all shipped since this head was written, and none of them could ever run: that button appears only when a device key exists, and nothing on the phone could create one. `CanUnlockWithDevice` was false on every launch of every phone. This is the missing half. **The offer is on PREFERENCES**, which held a PendingScreen until it had a setting on it. It is there rather than beside the button it turns on because registering needs an unlocked keychain and a reachable server — the vault has to be open to seal the bundle, and the wrap has to reach the account or a phone somebody has lost could never be revoked. Neither is true on the lock screen. One card, and exactly one of its three blocks is ever drawn: the offer, the withdrawal, or the sentence saying this phone has nowhere to keep a key. That is `CanRegisterDevice` / `CanForgetDevice` / `HasNoDeviceKeyOption`, which are two flags and not one and its negation for the reason written where they are set — a phone with no screen lock and a phone already registered are both "cannot register", and only the second has anything to take back. The withdrawal has no confirmation, deliberately, and the sentence above it carries what the desktop puts in a tooltip this head has no room for. `StatusMessage` is on the screen because it is the only feedback this head has once the system's own dialogue has gone. **Two things would have been wrong in the feature the moment it worked.** `Environment.MachineName` answers `localhost` on Android, and registering names the device — so every phone would have arrived in the account's device list as another identical row, on the very screen a lost handset is revoked from. `PhoneEnvironment.DeviceName` was already written and never called; the shell now takes it as an optional constructor argument that the desktop does not pass, and it reaches enrollment, registration and every connection log entry. That was gap §7 of docs/android-port.md, and it is now closed. And the status line said "Waiting for Windows…" over an Android biometric prompt. `GestureWait` picks the sentence from the platform rather than from a head, unlike the device name beside it: a device name is a fact about one handset only the head can read, and which dialogue appears is a fact about the operating system this assembly is running on. Two tests cover the seam — the injected name reaching the account, and the default still being this machine's own name — and `FakeVaultServer` records what each device called itself, because the name is the only part of a registration a person ever reads. The gesture itself is unreachable from any test process, so Phase 13 of docs/manual-checks.md carries five checks, including that enrolling a new fingerprint in Android's own Settings destroys the key. That one is the property that makes this a fast path rather than a weakening of the passphrase. |

Give the phone the second design, and both heads the palette it arrives with
The Android v2 design is what this head draws now: four destinations in a bottom bar — Hosts, Terminal, Keychain, More — with snippets, SFTP, S3, logs and preferences one tap deeper behind the last. The first design's four had nothing behind them, which is what made a hub worth building. The palette moved from green-black to blue-black, and it moved in the shared project because that is where it lives and the desktop v2 specifies the same seventeen tokens. One colour changed meaning rather than value, and it is the only semantic change in the file. Green used to *be* the accent, so Ellipse.dot.live filled with Accent and "the thing to press" and "a shell is open on this host" were the same colour by construction. v2 makes the accent blue and keeps a green for status alone, which finally separates them: Live is that green and nothing merely interactive may use it. The accent is also two colours now — Accent fills, AccentText writes — because a row of chips in the fill colour is a row of things that all look like the primary action. A palette is not one file, which is the part worth knowing before the next one. Nine hex literals lived outside it: the nav bar's own label colours, the accessory keys and their Ctrl-latched state, two scrims, the window background Android paints before Avalonia has a frame, and the launcher vector. The two C# sites now resolve from the dictionary by name rather than restating it. The renderer's page cannot — it is served to a WebView over a loopback socket — so terminal.css and terminal.js keep hand-copied values and say so at both sites. ShellScreen gained More and Buckets, appended rather than slotted in. SFTP and S3 are one screen over one TransfersViewModel differing only in which picker they offer, and the kind is set by the button that navigates rather than on arrival — doing it in OnScreenChanged made every arrival at Transfers force the picker back to hosts, including the desktop's own rail arriving at a screen with a bucket already open. It refuses to change kind while a session is live, because there is one session behind both destinations and switching under it would title a screen S3 while it listed an SFTP host. What the design draws and this does not, on the usual grounds. The FORWARDING screen: nothing here forwards anything, so every toggle would be a control with no effect — it is a paragraph on the hub naming the absence, for the reason the desktop keeps TEAMS in its rail. The terminal's `23 ms · fwd 5432`. An ED25519 badge and a SHA256 line on keychain cards, which need an algorithm field and a fingerprint the item type does not have. An `agent` chip, for an agent that does not exist. Snippet run history and exit codes. The Logs FOLLOW pill, which claims a live tail over records that are written once at close and read when the screen opens, and the severity filter, which has nothing to count — that chip row is spent on the real choice, which of the two logs. S3 bucket totals and lifecycle. And the + on HOSTS, which would open a host editor this head has not got. SFTP is browse, open and delete. Both transfer commands work, and what they work against is the local pane: QueueDownloads writes to Path.Combine(LocalPath, name), and LocalPath starts at SpecialFolder.UserProfile, which on Android is the application's own private directory. A download would have reported success and left the file where the person who asked for it cannot open it, which is worse than not offering it — a refusal is visible and a file in /data/user/0/ is not. The queue is not drawn either, since nothing here can put anything in it. Both return with the document picker. The foreground service still counts zero transfers, and the reason moved rather than went away. Four defects worth naming, because three of them are the kind that compile. A Button as a ListBox ItemTemplate swallows the pointer press before the list sees it, so the files listing selected nothing and every command reading the selection did nothing — the row is a Border now and the phone-only single-tap-to-open is a Tapped handler, which also keeps a desktop single click from walking into directories. Avalonia type selectors are exact, so TextBlock.fingerprint never matched SelectableTextBlock and every fingerprint on this head rendered proportional and unwrapped: that was breaking the never-truncated rule on the host-key sheet already. The new two-level hierarchy had no handler for the system back gesture, so back left the application from a log screen. And the tab's close cross had shrunk to a 30x32 target flush against the select target, which is the one control here that ends a shell with no confirmation and no undo. Fingerprint unlock is raised on arriving at the lock screen rather than waiting for its button, which is still there. Only at launch: a lock the user asked for is not answered with an immediate request to unlock, which makes LOCK look inert and trains the reflex of authenticating at a prompt nobody asked for. And once, because a declined gesture leaves the passphrase box exactly where it was and a prompt that came back after being dismissed would be a modal you cannot get out of to type into it. Two fixes fall on the desktop. Its file listing coloured directories with Info and executables with Accent, which was blue against green and is now two steps of one blue; an executable is Live now. And a bucket's folders were drawn with a 0001-01-01 timestamp, because a prefix has no modification time — blank now, for the reason a directory's size is blank. Verified by the whole suite: 1309 tests over nineteen projects, none failing, including the layout suite that stands up real Avalonia and parses every desktop screen. Both heads build. Not verified on a device — nothing in this head ever has been; see docs/android-port.md.

Give the phone the rest of its screens, and a way in
All seven screens of the design, plus the two it does not draw because it starts at an enrolled phone: naming a server, and choosing a passphrase. The five states docs/android-port.md worried about losing at 360dp are all here and none of them softened. The changed-key refusal is a full-screen panel rather than a bottom sheet, because a sheet is swipe-to-dismiss by convention and that screen must have no way forward. The recovery code raises FLAG_SECURE for its own state and lowers it afterwards, so the sentence about screenshots is true rather than decorative. The delete confirmations keep their counts and replace the row in place. Signing in works, and the seam it needed is worth more than the implementation: IAuthorizationCallback now sits between OidcClient and the loopback listener, so the two heads differ in where the response arrives and in nothing else. PKCE, the state check, discovery, the token exchange and the key binding stay one implementation — a second OIDC client would be a second place for a security bug to live. The phone registers a private-use scheme with the system rather than binding a loopback port, which on a shared device any other app can do first. The accessory key row needed TerminalWorkspace.SendInputAsync: ordinary typing goes from the renderer straight down the socket, and there was no way in for the keys a software keyboard does not have. Ctrl latches, because one thumb cannot chord, and the latch is drawn — a modifier that is on and does not look on is how somebody sends ^L to a database prompt believing they typed an l. 597 client tests green, including two new ones for the input path and one for the terminal surface command. Nothing has run on a device. |

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. |
