jaap-jan 48ea5e22d5 Actually keep the phone's sessions alive when the app is backgrounded
The foreground service existed, and four defects in its wiring meant it
mostly did not run. A shell opening was never announced to it — only the
ending was — so the service never came up for a shell at all. An idle
connected Files session counted as nothing. Every refresh restarted the
service, which Android 12+ answers with a crash the moment the app is
backgrounded — a transfer finishing in the pocket took the remaining
connections with it. And POST_NOTIFICATIONS was declared but never
requested, so on Android 13+ the receipt was silently invisible.

Updates while backgrounded now go through the notification manager; a
foregrounded refresh still prefers a real start, so a stop still in
flight cannot leave an orphan receipt over an unprotected process.

jaap-jan b4a6c19ac1 Let the phone replace itself, and give CI a channel it may sign
ci / build and test (push) Successful in 1m53s
ci / android head (push) Failing after 32s
ci / api image (push) Successful in 28s
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.

jaap-janandClaude Opus 5 57d4b30557 Put the app's own mark on the launcher
ci / build and test (push) Failing after 3s
ci / api image (push) Skipped
ci / android head (push) Failing after 2s
The sign-in and locked screens both draw the same thing — a square outline in the accent
with >_ inside it — and the launcher was still showing the stock Android silhouette, so the
icon somebody taps and the icon the app opens onto had nothing to do with each other.

Redrawn as a vector rather than exported from the screen as a bitmap. There is one geometry
here and no set of density buckets to update four of and forget the fifth, and the accent
stays a number that can be diffed against Palette.axaml rather than a colour baked into a
PNG. The hex is written out because an Android resource cannot reference a XAML dictionary
— the same duplication colors.xml already carries for the window background, with the same
obligation attached.

Adaptive only, no raster fallback. Adaptive icons landed in API 26 and this head requires
28, so there is no device it ships to that would need the bitmaps; density buckets exist to
choose between PNGs and there is nothing to choose. The background layer is the same
@color/dodo_window as the window and the status bar, so the mark sits on the app's own
near-black rather than on a second one almost like it.

Two departures from the screen, both because a launcher is looked at much smaller than a
sign-in header. The box is 42 across rather than the 48 that first suggested itself: 72 of
the 108 survives masking, but that is a width, and a square meets a circular mask at its
corners — at 48 they land 33.9 out against a radius of 36 and read as clipped despite
technically clearing it. And the strokes are 2.2 and 2.8 where proportional fidelity to a
1px border on 44px would be 1.0, which a launcher drawing this at 48dp would render as half
a pixel of nothing.

A monochrome layer too, for the Android 13+ themed-icon setting. Without one a launcher
with themed icons on falls back to the full-colour icon, which would leave this the single
green thing on an otherwise recoloured home screen.

Verified in the packaged APK: the icon resolves at all five densities, the three layers
resolve, and the compiled vector carries the geometry above. The launcher rendering itself
was checked against local renders under circular and squircle masks at 144 and 64 px, not
on the device — the phone was locked.

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.
