jaap-janandClaude Opus 5 43d76d0f2d Let the suite run on Linux, and fix the three things that stopped it
ci / build and test (push) Failing after 1m47s
ci / api image (push) Skipped
ci / android head (push) Failing after 5s
The pipeline finally reached the tests and found four failures. None was the pipeline's,
and only one of the four was a test being fussy about a platform rather than telling the
truth about one.

The local pane's roots bar was the real bug. LocalDirectory.Roots built it from
DriveInfo.GetDrives on every platform, and its own summary — "the drives on Windows, and
the root elsewhere" — had been describing an intention rather than the code for as long as
nobody ran it off Windows. On Unix that call answers with every mount the kernel holds:
/proc, /sys/fs/bpf, one per installed snap, /run/user/1000/doc, some forty on an ordinary
laptop. The transfers screen draws a button per root, so the bar ran to about five thousand
pixels inside an eight-hundred pixel window. Anybody running the Linux build has been
looking at that.

Filtering GetDrives is not the fix and the comment now says why at length, because it is
the obvious thing to try: DriveType answers Fixed for / and /home and equally for every
squashfs snap, for efivarfs and for tracefs, while /boot/efi comes back Removable, and
DriveFormat would need a hand-kept list of every virtual filesystem Linux might grow. So
Unix now names what somebody would want instead of subtracting what they would not — the
root, their home, and whatever is mounted under /run/media/<user>, /media, /mnt or
/Volumes. Anything else is still reachable by navigating from /, which is what the pane is
for. Windows is untouched.

ClientPathsTests looked for "odoSSH" in the profile directory. ClientPaths spells it
DodoSSH on Windows and dodossh on Unix deliberately, one per platform convention, and that
substring was clever enough to survive either spelling of the leading D while still only
ever matching one of them. Now OrdinalIgnoreCase.

WhyTheWindowItselfIsNeverShown asserted a COMException with HResult RPC_E_CHANGED_MODE,
which is WebView2 refusing an MTA thread — a Win32 component raising a COM error. On Linux
the adapter is a different implementation with no apartment to disagree about, so showing
the window works and Should.Throw catches nothing. Skipped there rather than loosened to
accept both outcomes: the assertion is the documentation in that test, and one that passed
everywhere would have stopped recording the constraint it exists to record.

The fourth was CI's alone, and the diagnosis is the useful part. All 69 layout tests failed
on the runner while 6 failed here, which looked like missing fonts and was not: Avalonia's
headless renderer is Skia, libSkiaSharp.so links against libfontconfig, and without it the
suite dies in HeadlessUnitTestSession with a TypeInitializationException on SKImageInfo
naming none of its actual subjects. The job installs the one library now. Verified in a
container where fc-list returns zero and the suite passes regardless, because the
application carries Inter itself — fonts were never the problem, only the thing that would
have looked for them.

The whole solution now passes on Linux: 19 suites, 1295 tests, 0 failures, 4 skipped, the
end-to-end Testcontainers suite included. README and platform-flags.md said testing was
Windows-only, which CI now contradicts on every push, so both say what is true instead and
the two findings are written down where the next person will look for them. macOS is still
untested and now says so on its own rather than hiding inside "not Windows".

jaap-jan 49f617b450 Wire the Avalonia shell to the vault
The host list now comes from the vault instead of from a form. A fresh
machine takes a server URL, signs in through the browser, enrolls, and
from then on opens with the passphrase alone.

DodoSSH.Client.Session is the composition layer: where a profile lives,
how it unlocks, and how a machine gets one. ClientPaths picks a
non-roaming per-OS directory — %LOCALAPPDATA% and never %APPDATA%,
because a SQLite cache that roams between two machines is a corrupt one,
and each machine's outbox is its own. SessionOpener needs no transport at
all and could not reach one if it wanted to; that is the offline unlock,
asserted rather than asserted about. A wrong passphrase, a stale KDF and a
grant revoked by a rekey are three different answers, because the remedies
are three different things and telling someone to retype a passphrase that
was never the problem is worse than saying nothing.

The shell's states are the onboarding story. The recovery code gets its
own state that cannot be clicked past: it exists for one moment, losing it
with the passphrase loses the vault, and there is no server-side reset by
design. It is dropped from memory on confirmation rather than merely
hidden.

Sign-in is a delegate over IVaultServer, so the whole state machine runs
in a test against an in-memory server — no browser, no identity provider,
no toolkit. The view models are plain observable objects, which is what
makes that possible. What it does not cover is whether the XAML binds to
the right names; that needs a rendered tree and Avalonia.Headless, and is
its own piece of work.

Three things found by doing it rather than by reading it:

- Pooled SQLite connections keep the database file open after the last
  context is disposed. On Windows that means locked, so the application
  could never replace its own cache — and a test could not clean up after
  itself, which is how it surfaced. Dispose now clears the pool.
- EF's SQLite provider puts the database in WAL mode, so the cache is
  three files. A comment in ClientCacheFactory claimed the opposite;
  reading PRAGMA journal_mode off a real launch settled it. WAL is the
  right mode here — a sync pass writes while the interface reads — so the
  comment was wrong on the merits as well as on the fact.
- Enrolling a device key with nowhere to keep the private half would put a
  wrap on the server nobody can open and make the device list claim this
  machine can unlock without a passphrase. Device binding is now optional
  and the shell declines it until the OS keystore is wired.

Verified on Windows: the client created %LOCALAPPDATA%\DodoSSH\cache.db
and migrated it on first launch, and msedgewebview2 held an established
connection to the data plane while the unlock overlay covered it — which
is the point of covering the WebView rather than collapsing it, since a
NativeWebView that is never laid out is never realised.

630 tests, up from 593. The recovery-code gate and the offline unlock were
each verified by breaking them and watching the right test fail.

Still to do for M1's actual definition of done: the manual run against the
real API and a real Keycloak. Credentials are not a synced entity type
yet, so a connection still asks for a password, and the interface says so
rather than implying otherwise.
