jaap-jan 38d8706784 Give the phone a way to enrol the fingerprint it already unlocks with
ci / android head (push) Failing after 4s
ci / api image (push) Successful in 35s
ci / build and test (push) Successful in 1m36s
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.

jaap-jan 562fb444a8 Merge main into the phone connections branch
ci / build and test (push) Canceled after 46s
ci / android head (push) Canceled after 0s
ci / api image (push) Canceled after 0s
Main had already taken this branch's first two commits, so what merged is the
Connections work against three things that landed beside it. Four of the six
conflicts were prose about arrangements both sides changed; two were real.

**The phone hub gained a Teams row while this branch was moving the keychain
onto it.** Both are additions to `IsMoreSurface` and both belong: teams because
the desktop reaches them from its rail and the phone through the hub, the
keychain because a bottom bar is for the places a session moves between. The
membership test, the back gesture's first case and the hub's own arithmetic all
take the union. The distinction is now written down rather than implied — teams
is the design's count plus one, and the keychain is the only rearrangement of
it: the bar lost a slot to gain that row.

**`ConnectAndAnnounceAsync` was the real one.** Main gave it
`RememberTypedPasswordAsync`, which binds the password that just worked to the
host it worked on; this branch had replaced the `HostRowViewModel` that method
needs with a four-field `ConnectionTarget`. Keeping both meant deciding what a
manual connection does with a password that succeeded, and the answer was
already written on the screen it is typed into: nothing. There is no item to
bind a credential to and none to bind it on, and that path saves nothing by
design.

So `ConnectionTarget` carries the row again — as a nullable, in place of the
host id it had, with `HostId` derived from it. Two things read it and both are
things that can only be done to a keychain item rather than to an address:
naming the log entry, and keeping the password. Null is not missing data there;
it is the whole of what makes the manual path different, and having one field
rather than two keeps "was this a keychain host" a question with one answer.

The desktop's rail lost SFTP and S3 to the tab strip on main, so the README's
"a rail with nine slots has room" was true when it was written this afternoon
and is not now. It says the room rather than the number.

Phase 11's four new device checks and main's Phase 12 on teams were the same
conflict twice — two appends to the end of one file — and both are kept.

Verified after resolving: the solution builds, the Android head builds clean,
and 837 tests pass across the seven client suites, including main's own additions
(233 shell, 79 layout, 240 domain, 118 sync, 54 session, 74 terminal, 39
storage).

jaap-jan f5ffd1983d Make Connections the place a connection is made, and put the keychain away
Four changes to the phone, and the last one needed the connect path taking
apart.

**The bottom bar is three entries.** The keychain moved onto the hub, which is
now SETTINGS with a gear rather than MORE with a hamburger. A bottom bar is for
the places a session moves between, and keys, credentials and tags are managed
occasionally and then left alone — which is the shape of everything already
behind that hub. With the keychain on it, "more" stopped being a description of
what is there. `ShellScreen.Vault` joining `IsMoreSurface` is the whole of the
change: the tab that lights, the header that stands down and the back gesture's
first case all read that one property, which is why the switch mirrors it by
construction rather than by a second list. The keychain screen grew the header
every hub screen has, because the shell's own is not above it any more and
without one there would be no back arrow and nothing saying what the list is.

The desktop keeps its Keychain rail entry. A rail with nine slots has room, so
this is the second thing the two heads arrange deliberately differently, after
the hub itself.

**Terminal became Connections**, and the word does more work than a rename
usually does — see below. The enum member stays `ShellSurface.Terminal`, for
the reason the tab was never called Vault: the surface is a terminal, and the
word a user reads is the product's.

**The + puts the software keyboard away.** It sits above a terminal somebody is
typing into, so the sheet it raises was arriving underneath a keyboard covering
the half of the screen the sheet is on — and worse, laid out into the strip
left above it, since the keyboard's inset shortens everything this head draws.
Avalonia cannot do this and it is worth knowing why: `TopLevel.InputPane`
reports the keyboard and offers nothing that closes one, because the framework's
model is that it belongs to whatever has focus — and this keyboard was raised by
the `WebView`'s own text input, by a native view Avalonia's focus manager never
owned. Clearing Avalonia's focus leaves it exactly where it is. So
`Platform/SoftKeyboard.cs` asks `InputMethodManager`, off the decor view's
window token, and every step of it is allowed to be absent.

**With nothing open, Connections is a connect screen rather than an empty
state.** A box taking `user@host` or `user@host:port`, a password, and the
machines most recently connected to underneath. The box is the only path in this
product to a machine the keychain has never heard of, which is a real case it
had no answer for: an address somebody was handed five minutes ago. A typed
password and nothing else — offering the keychain's keys would be a second
binding resolution beside `TryBuildAuthentication`, and the argument against a
second one is written there at length. Nothing typed is saved, and the screen
says so: a machine worth keeping belongs on HOSTS, where it can carry a key, a
group's defaults and a name.

The recents come out of the vault's own connection log rather than a list kept
in this process, so they survive a restart and arrive on a new phone with the
keychain. Deduplicated by address, because this is a list of places and not of
events, and capped at six so the box stays above the keyboard. Emptied when the
vault is — they are decrypted entries naming where somebody works, and a lock
that left them on screen would be a list still readable after every key that
decrypted it was zeroed. Tapping one leads to whichever of two things it is: a
keychain host goes to that host's connect bar, where its key, its password box
and its refusals already live, and an address goes back into the box, without
the password, whose absence is the point of that path rather than a gap in it.

**The connect path was shaped like `HostRowViewModel` all the way down.** The
log entry, the identification, the failure record and the retry all took a row.
They take a four-field `ConnectionTarget` now, so a connection to an address
shares the ladder of refusals, the host-key question and the tab's lifecycle
rather than growing a second copy of them. `ConnectionRecorder.Record` and
`Identify` have always taken a nullable host id, so the log could already hold a
connection with no item behind it.

One behavioural change falls out of that and it is the one to know about:
**trusting a host key now retries the attempt that raised the question** instead
of re-running whichever host is selected. That was correct while a selected host
was the only way to connect; with a manual target it would dial a different
machine, or refuse with "choose a host first" over a key the user has just
agreed to trust. The test selects a host first, so a regression cannot pass by
connecting to the wrong thing successfully.

`LogsViewModel.ReloadAsync` split so the connections half can be read alone.
Reading the keychain's activity for a screen that offers neither would double
the decryption on the list that was already the expensive one.

Twelve tests: the parse grammar as a theory over seven refusals, the dialled
request, the retry, and both branches of tapping a recent row. The recents rows
are built by hand rather than connected-and-closed — what those tests are about
is which branch a row takes, and driving it through the recorder's queue would
test the recorder, which `DodoSSH.Client.Session.Tests` already does. What needs
a device is phases 11.6 to 11.9 of `docs/manual-checks.md`.

jaap-janandClaude Opus 5 a43286ece8 Let a team change hands, and be joined by somebody with no account yet
M3 built teams and stopped short of the two operations that decide who
controls one. Both were written down as refusals rather than omissions:
ADR 0009 listed ownership transfer under "deliberately not built", and
design-import-gaps said an invitation needed "a token with a lifetime and an
outbound mail path". One of those reasons had expired and the other never
applied — an invitation does not need a token if it is not a thing anybody
presents.

Handing a team over is one write. The member you name becomes owner and you
become an admin, in a single transaction, because ownership is sole: promoting
first leaves the team owned twice, demoting first leaves it owned by nobody,
and there is nobody left with the authority to finish a transfer that stopped
in the middle. That is also why it is not two calls to the role endpoint, which
refuses Owner outright. The outgoing owner is demoted rather than removed —
removing them would revoke their vault key grants and flag every team vault for
rekey, which is a far larger act than the one asked for, and somebody handing
over a team is usually staying in it. It unblocks the thing that was impossible
before: an owner can now leave, by handing the team on first.

An invitation is a standing instruction rather than a message. This server has
no outbound mail path, so nothing is sent and there is nothing for the invitee
to present. The row says the next account signing in with that address joins
this team at this role, and telling them to sign in is the caller's job over a
channel this server does not carry. A link nobody can deliver would be worse
than none. It lives in its own table rather than becoming a membership with
MembershipStatus.Invited, and that member stays unwritten for the reason it
always was: team_membership.user_id is not nullable and carries a foreign key,
so somebody who has never signed in has nothing for that row to point at.
Widening it would make the unique index on (team, user) meaningless, because
PostgreSQL counts every NULL as distinct.

Verification is the security boundary, and nothing in this server read it
before. A claim requires the access token to assert email_verified. An
invitation decides what the server will serve, so one claimable by anybody able
to obtain a token carrying somebody else's address is a way into a team — which
is precisely the attack OidcOptions.AllowEmailLinking exists to refuse, and it
would have been reintroduced by the back door. There is deliberately no setting
that relaxes it: a flag that exists is one somebody turns on for the afternoon
their provider is misconfigured. Absence is refused rather than trusted, and
logged, because a provider that never sends the claim otherwise leaves every
invitation pending with nothing anywhere saying why.

Claiming happens at just-in-time provisioning and again on an hourly sweep. The
sweep is what makes it recoverable rather than one-shot — an invitation issued
between an account being created and that person next signing in would
otherwise be stranded for ever — and it shares its rate with the last-seen
write because both are housekeeping nobody is waiting on.

Archiving is refused while a team owns a vault, and that refusal is the end of
the road rather than a step on it. A team vault is readable because of
membership, so archiving one that still owned vaults would take them away from
everybody holding a key, including the caller, quietly and all at once. Nothing
in this product deletes a vault, so no order of operations gets past it today —
which is stated with a count of what is in the way, for the reason the SFTP
layer refuses a recursive delete: a refusal is visible and a quiet removal is
not. It is owner-only, as handing over is; renaming is not, because a rename is
visible to everybody and reversible by anybody who can do it. The slug is not
renameable at all: it is unique only among live teams, so a rename could take
one an archived team is still holding, and that team could then never be
restored.

LAST ACTIVE is real and coarse on purpose. UserAccount.LastSeenAtUtc is
refreshed on ordinary authenticated requests, at most once per account per
hour, through ExecuteUpdateAsync — user_account carries the xmin concurrency
token, so a read-then-write on the hot path would start losing races between
one user's own overlapping requests. An hour is the granularity the question is
actually asked at, and the interface draws it to the day rather than the minute
so it does not read as a precision that is not there. The remarks in Contracts
and in the view model that argued at length for the column's absence are
rewritten rather than extended; both had become false.

Two endpoints already existed and nothing called them. ChangeTeamMemberRole and
ListVaultGrants have been reachable since M3. The role picker refuses Owner
itself rather than letting the server do it, since the interface already knew
the rule; the key-holder list sits under the vault rather than beside the
member, because a grant is per vault and a count on a member row would imply
per-item sharing, which is M5. It lists withdrawn and stale grants and says
which they are — a list that dropped them would show a departed colleague as
merely absent rather than as somebody whose key was taken away — and staleness
is decided by comparing generations, since a grant can be Active and still open
nothing.

ADD MEMBER stopped being a dead end. An address the directory did not know used
to end at a sentence telling the user their colleague had to sign in first. It
invites them instead, from the same button, because which of the two applies is
a fact about the server's account table rather than about what the user is
doing; which one happened is reported afterwards, because that decides what
they do next. An address that merely has an account is invited rather than
refused: refusing would have made the endpoint an oracle for which addresses
have accounts here, answerable by anybody willing to create a team first.

The phone has a TEAMS screen, behind MORE, and it is the reverse of every other
row in design-import-gaps: a shipped screen the design had no slot for. It is
there because an invitation is claimed by signing in, so somebody told they are
now in a team is at least as likely to be holding a phone — and a membership
visible only on a head they never installed is one they cannot see. It draws
SHARE KEY and nothing that takes something away: wrapping a key is the one act
on that screen a server cannot perform at all, and the desktop guards its
revocations with a tooltip, which is a control a touch screen cannot show.

Two defects were found by an adversarial pass and both were green against the
whole suite at the time. The owner-only check on archiving and handing over had
been weakened to the admin check while their messages and comments still said
owner — and since nothing behind the archive endpoint re-checks it, an admin
the owner had promoted could have archived the team out from under them. And
the rename endpoint built its response with a hardcoded Owner role, so an admin
who renamed a team was handed a summary claiming they owned it, and a client
trusting that instead of re-listing would have offered them the two owner-only
buttons the server then refuses.

The new table gets its constraints tested rather than merely migrated: live
uniqueness per (team, address), the citext proof that an address typed by a
person matches one cased by a provider, and reissue after both revocation and
acceptance. The teams screen gets its first entries in the layout suite, at the
minimum window with every list populated and with each of the two states that
cover half of it — it had none, and it just grew four sections and a second
line in the member row.

jaap-janandClaude Opus 5 5593f337b6 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.
