jaap-jan 780f4bf892 Merge branch 'main' into the group's move and its deletion question
Main took the group's EDIT and DELETE off the GROUPS heading while this branch
was adding a MOVE beside them, so the conflict was about the same six pixels
from both directions. Main's answer wins outright, and it is the better one for
the reason its own message gives: a button beside a heading has no card under a
pointer to mean, and had to work its subject out from the selection or from the
trail. Moving a group had that problem worst of all — the thing it takes with it
is everything on the shelf, and "which shelf" is not a question a button there
could answer plainly.

So the MOVE button is gone and the menu entry it was drawn beside is the whole
of it. That entry was already in this branch, above the separator DELETE sits
below, and it needed no change: the card menu selects whatever was right-clicked
before it runs anything, which is exactly the aiming a group move wants.

Three things went with the button. ShowsGroupActions, which main deleted because
hiding buttons was all it did, and which this branch had extended to hide them
for the move panel as well. CanMoveGroupTarget, which existed to answer whether
that button was worth drawing — CanMoveSelectedHost stays, because the phone
really does leave the host's MOVE out rather than offer a refusal, and a menu
whose entries came and went would be a menu whose items move. And the two test
assertions that read them, which were describing the button rather than the
behaviour; what they were guarding is that the two panels never share the
moment, and IsConfirmingGroupDeletion says that directly.

The move panel and the deletion question both keep their place under the
heading, which is where the buttons were and is now simply where that section
puts things. They still exclude each other, by disarming rather than by a
visibility flag: MoveGroup clears a pending deletion and DeleteGroup folds the
move panel away.

Manual checks 3.3 was rewritten by main for the menu and by this branch for the
tick, and now says both; 3.3a is new and walks a two-level shelf across a vault
boundary, which is the half of this feature no headless test can watch land.

jaap-jan a86731ee08 Move the shelf as well as what is on it, and ask what a deletion takes
Two things about a group, and they turn out to be the same argument twice.

**A group can be moved to another vault, and it takes everything on it.** The
host's move shipped last week and stopped one level too low: moving twenty
machines into a shared vault meant twenty trips through a menu, and each one
arrived stripped of the group it had been filed under, so the shelf had to be
rebuilt by hand on the other side. Moving the shelf is what people were
attempting. MOVE sits between EDIT and DELETE over the group cards, and on the
card's own menu above the separator DELETE is below — the same place, and the
same reasoning, as the host pane's ⋯ entry.

**The whole subtree goes, and taking less was never coherent.** A group's
children are items of the vault it is leaving, so a parent moved alone leaves
them naming a tombstone and they surface as roots in the vault the user has just
emptied: half a shelf here and half there, from one gesture that said "move
this". The hosts are the same argument and are the half the request was about.

The groups go first, top down, and the hosts last. Each item is re-sealed under
the destination's key and takes a new id — VaultItemRepository.MoveAsync, which
HostGroupRepository now exposes — so nothing pointing at a group can be written
until that group has landed and its new id is known, and a child's parent must
already be over there. What an interruption leaves is therefore hosts still in
the vault they started in, under UNGROUPED: visible, and re-movable. The reverse
order would leave hosts in the destination filed under nothing.

The parent stays behind and the tags are dropped, which is the host move's rule
one level up: both are items of the vault being left, so a reference carried
across would resolve on the machine that moved it and dangle for everybody else
in the destination. The moved group arrives at the top level, and the panel says
so before the press rather than the status line saying it after. Keys and
passwords are kept — those genuinely resolve across vaults, and clearing them
would take a working host and make one that cannot connect — and any now outside
the destination is named, because that is precisely what the other members of it
will not be able to resolve.

Refused as a whole where anything under the group was written by a newer client,
rather than skipped item by item: a move that left behind what it could not
re-encode would file some of the shelf in one vault and the rest in the other,
which is the state this exists to prevent. Refused with a host editor open, as
the drop gesture is, because it rewrites hosts. And the walk carries a visited
set, for the reason every walk over this tree does: a group that is its own
parent — which two offline clients can build and no editor was ever shown —
would otherwise be appended to the move list for as long as there was memory.

**Deleting a group now asks what should become of the hosts under it, and that
reverses a decision this repository had written down.** The deletion did not
touch them: the reference was left dangling, the list resolved it to nothing,
and the machines turned up under UNGROUPED. That was right for one of the two
things people delete a group for and wrong for the other — a heading being tidied
away should leave its machines alone, and a project that has been decommissioned
is a shelf and everything on it — and nothing in the code can tell which of the
two it is looking at. So it is asked.

A tick rather than a pair of options, because the two answers are not equally
weighted: keeping the hosts is recoverable and deleting them is not, so the safe
answer is the one that needs no decision. It is off on every question, including
the one that disarms it, or a tick left standing would destroy the next group's
machines on the strength of a decision about the last one's.

Once the deletion knows which hosts it means, leaving them naming something that
has gone is a state kept for no reason, so the unticked answer writes too: N
hosts with the reference cleared, where the ticked one writes N tombstones. That
is the N writes HostGroupRepository refuses to hide behind a DeleteAsync
overload, made where somebody asked for them and where the count is on screen
first. The nested groups take the deleted group's place in the tree rather than
being orphaned to the top level. A read-only host is skipped, counted and named,
because unfiling it would re-encode a payload this build cannot represent — and
the cost of skipping is a dangling id, which every reader here already survives.

**Both are the desktop's alone**, and that is not an omission. The phone draws
groups as headings in the host list and has never had a way to delete or move
one; the two panels take the row of buttons over the group cards, and there is
no such row on a 360dp screen to take.

One test had to change its premise rather than its assertion.
EditingAHostWhoseGroupIsGone built its dangling reference by deleting the group,
which now unfiles instead — so it imports a host naming an id nothing resolves,
which is what a group deleted on another machine actually looks like and is the
only way that state still arises. The picker's placeholder is still needed and
still covered.

Four places said an item could not be moved between vaults. Two were about a
group and were true when written; the other two were left stale by the host's
move. All four now say what is true, including the design gaps document, where
the chevron beside the vault name stays undrawn for the reason it already had.

jaap-jan 4b706bc3c3 Say when a vault has moved, so nobody waits out the minute
The delta pull was cheap enough to run on a timer and the client did, once a
minute. That is fine for a machine and wrong for two people: an edit a colleague
makes is up to a minute stale, which is long enough for both of them to make it
and produce a conflict neither needed to have. Shortening the interval is the
obvious answer and the wrong one — it costs a request per client per interval
whether or not anything happened, and it converges on a busier server that is
still late.

So the server now says so. A client holds a WebSocket open at GET /api/v1/events,
subprotocol dodossh.events.v1, and gets a line down it when something it can read
has changed. ADR 0012 has the reasoning; three parts of it are worth repeating
here, because they are what everything else rests on.

**What crosses the socket is a notice, never data.** A frame names a vault and
how far its change log has got. No item, no ciphertext, not even which item it
was. The client's answer is the delta pull it would have run anyway, so there is
still exactly one code path that applies a change to a keychain, and it is not
this one. Pushing the items themselves would save a round trip and fork that path
in two, with the cursor, the merge and the tombstone rules duplicated across both
— ADR 0003 put every mutation through one write path for that reason, and this
keeps every read on one for the same one. It also makes a dropped notice
harmless, which is what lets the fan-out below be as simple as it is.

**Polling stays, and is what guarantees a pass.** The minute timer is unchanged.
A network that eats WebSockets, a server with Events:Enabled off, an older
server, a proxy that will not upgrade, a notice dropped under backpressure —
every one of those leaves a client behaving exactly as it did before this commit.
Nothing is reachable only over the socket and nothing is meant to become so;
VaultViewModel's AutoSyncInterval remark now says that where somebody changing it
will read it.

**The bearer token authorises the upgrade, unlike the relay's ticket.** Not an
inconsistency with ADR 0004: the relay's socket is a byte pipe whose whole
authorization decision — which host, which IPs, which port — is made before it
opens and never revisited, and it is the extraction seam for a process that must
hold no ACL code. This one is a view of the caller's own vault list and has to
keep answering "what may this account read" for as long as it is held. A ticket
would carry that answer in a token and be wrong the moment the account's access
changed. The two bounds that arrangement needs are met rather than waved at: the
socket is closed at the token's exp with close code 4401 and the client comes
straight back with a fresh one, and the vault set is re-resolved every few
minutes as well as on the changes known to affect it. Both bound *metadata*,
because a notice contains nothing else and reading a vault still needs a key this
server has never held.

**The fan-out.** VaultEventHub is a singleton holding the sockets this node
accepted; publishing walks them and asks each whether it cares, rather than
keeping a vault-to-subscriber index that every re-subscription would have to move
entries between under a lock publishing also takes. At a few hundred sockets per
node and an event rate bounded by how often people edit keychains, the walk is
not measurable and its races are obvious. Per-connection queues are bounded and
drop the *oldest*: a notice means "pull vault X, which is at least at sequence
N", so the newest subsumes what it displaces and the client's answer is identical
either way — which is what lets the publish path be void, never block, and never
fail.

Announced from the endpoint rather than from SyncService, and that placement is
the point: by then the push has committed and released the per-vault advisory
lock. From inside it would name a sequence no reader can see yet and would hold
the lock that serialises writers across a socket write. Only the highest
*applied* sequence, so a batch of pure conflicts announces nothing, and a
duplicate — already announced when it first landed — announces nothing either.

Grants and membership publish too, and those take the *recipient* rather than the
actor. This is what AdmitNewVaultsAsync has been apologising for since sharing
shipped — "the recipient is handed nothing, there is no push channel" — and the
README with it. A vault shared with somebody now turns up as it is shared. The
comment and the README paragraph both say what is true now, and both keep saying
that the pass is what *discovers* the vault, because a client with no socket has
to arrive at the same place.

**On the client**, VaultEventStream is really a reconnection policy wrapped round
a ClientWebSocket: a dropped socket is the ordinary case here — laptops sleep,
proxies time out, tokens expire, servers are redeployed — so nothing in it treats
a failure as exceptional, and every path ends in "wait, then dial again". A
connection that lived long enough to say hello resets the backoff, so a laptop
that woke, worked, and lost its network an hour later does not inherit a
minute-long wait it has already proved it need not take. A 4401 close skips the
backoff entirely and asks the token provider again, which is the whole reason
that close code is distinct. A server that does not advertise the events feature
gets IdleVaultEventStream, which never delivers — so IVaultServer.Events is never
null and every caller stays on one shape, because the correct behaviour without a
socket is the behaviour with a silent one.

The shell's background loop now selects between the timer and a notice, and both
waits are held across iterations. That is load-bearing rather than tidy:
PeriodicTimer permits one outstanding WaitForNextTickAsync and throws on a
second, and an abandoned channel read stays registered and consumes the next
notice written. Either defect leaves the first notice working and every one after
it silently lost, which is why NoticesKeepWakingTheLoop_NotJustTheFirst pushes
three and not one. Notices are coalesced over a quarter of a second, so one
person's save — a host and its log entry are two items — and a colleague clearing
a folder each cost one pass rather than a dozen.

**The kind is a string, not an enum**, and that is a compatibility decision.
UseStringEnumConverter throws on a value it does not know, so a newer server
sending a kind an older client had never heard of would not add an unreadable
frame — it would break that client's socket outright. A string is ignored
instead. ProblemCodes is the same shape for the same reason.

**Tested on both sides, through the real pipeline.** The endpoint suite opens a
genuine socket against TestServer and proves a push produces a notice, that
another account's push does not reach it, that a ping is answered, and that a
frame this server cannot parse does not end the connection. Two of those assert
on *ordering* rather than on absence within a timeout — the stranger's write goes
first, so a socket that leaked would have announced it before the one the test
waits for — because "nothing arrived in two seconds" is a test that passes on a
slow machine for the wrong reason. And ANoticeCarriesNoCiphertext asserts on the
bytes that crossed the wire rather than on the record's fields, since the latter
would only prove that this type has no payload member, which is a tautology; the
former is what catches a field added later without anybody thinking about
disclosure.

The client suite drives VaultEventStream through an injected connector, because
the one thing a test cannot do to a real network is make it fail on cue — and
failure is the entire subject. The shell suite proves a notice produces a pull
inside ten seconds against a sixty-second timer, so the timer cannot be what
caused it.

**Two limits, stated rather than left to be discovered.** Fan-out is in-process,
so a deployment running more than one API replica only pushes for writes its own
replica handled and the rest arrive on the timer. IVaultEventPublisher is the
seam a PostgreSQL LISTEN/NOTIFY backplane implements and it is deliberately not
implemented: an untested backplane is worse than a documented gap, and multiple
replicas degrade to the behaviour before this commit rather than breaking. And a
client is notified of its own writes; it pushed, so it already pulled, and the
extra pass finds nothing. Suppressing that echo correctly needs a per-device
identity on the socket, and the same user's other machines must still be told.

Manual checks phase 15 covers what no test here can reach, which is the network
in between: a proxy that will not upgrade, one that drops an idle socket without
telling either end, a laptop lid, a token expiring. Every one of those is
invisible inside a test host, and every check there passes only if the change
arrives quickly *and* still arrives with the socket taken away.

ADR 0012 also fixes one thing about the shared terminal session this is the
transport for, so it need not be renegotiated later: session data will be binary
frames on this same socket, because base64 in a JSON envelope is the wrong shape
for the one payload here that is continuous rather than occasional. Two questions
it explicitly does not answer by implication — whether those bytes go through the
API at all, and what end-to-end encryption means when the second party watches a
stream rather than holding a key — are ADR 0001 questions and get their own
decision.

1512 tests pass. DodoSSH.SystemTests was not run — it needs the whole compose
stack — so the end-to-end path is unverified for this change beyond what the
manual checks describe.

jaap-jan 3f419cb19b Let one card be selected at a time
The hosts screen draws two grids, one above the other, and each is a ListBox
with a selection of its own. Nothing joined them, so a group card and a host card
could be lit at the same moment — two chosen things, under two pairs of buttons
of which only one would act on whichever the eye had settled on. Both grids mark
a selection the same way, so there was nothing on screen to say which of the two
the next press belonged to.

They share one mark now. Selecting a host clears the group and selecting a group
clears the host, and that second one takes the detail pane down with it: a pane
about one machine cannot go on standing beside a marked group, because nothing
on it would be about what is selected.

Losing a selection deliberately clears nothing. A null arrives whenever either
list is rebuilt — every keystroke in the filter box and every background sync —
and treating that as somebody deselecting would take the mark off a group card
because a search emptied the grid beneath it.

The reload needed the same guard for the same reason. It falls back to the first
host when nothing is selected, which is what puts a target under CONNECT on a
fresh unlock; with one mark between the two grids that fallback would have
unselected a group nobody had touched, once a minute. It is skipped while a group
holds the selection, and it moved into a method of its own because the comment
saying why pushed ReloadHostsAsync past sixty lines.

One consequence needed handling rather than accepting. The phone's only route
into the group editor is a button on a heading in the host list, and it worked by
selecting the group first — which under this rule takes the highlight off the
machine somebody was about to connect to, on a screen that draws no group cards
to say where it has gone. EditGroup takes the group as an argument now: the
heading passes its own row, and the desktop's button beside the cards passes
nothing and still means "the card that is selected".

What the tests hold is the half that lives in the controls. Clearing the property
has to reach the list that is drawing the card, and a selection nulled in the
view model while the card stays highlighted is the exact failure this is about —
so the rule is driven on the real screen, in both directions, against the
ListBoxes' own SelectedItem. The desktop's EDIT is pressed through its binding
for the same kind of reason: a command refusing the button's empty parameter
would be a button that never fires, and nothing about the markup would say so.

jaap-jan c39df3f51e Share the shelf as well as what is on it, and ask a group which vault
A group is where hosts are filed and what lends them a port, a username and a key,
and until now it could only ever be made in the vault this machine files new items
into. So sharing a vault shared the machines and not the arrangement: a colleague
opened four hosts filed under a group they could read the name of and nothing else,
and the group a teammate made had no card, no heading and no way to be corrected
from the screen looking straight at the hosts inside it. Recorded as half shipped in
docs/design-import-gaps.md, and this is the other half.

The list stopped being the active vault's. It was narrow for two stated reasons —
a row shown across vaults has to carry which vault it lives in, because rename and
delete both need it, and two vaults may hold a "production" each, which a layout
with one heading per group cannot tell apart — and both are now paid for rather than
avoided. Every row carries its vault, the badge beside the name says which, and the
two cards sit side by side saying what they are.

The three shapes of the group read are now deliberately different sizes. The list is
what a person looks at, so a hidden vault's groups leave it: a card that cannot be
opened onto anything is worse than no card. The per-vault lists are what a picker
offers, because a picker is always asking about one vault. The map is what a host's
GroupId resolves through, and it stays widest of all — including over hidden vaults,
since a group lends a port and hiding a vault must never change what one of its
hosts dials. RebuildGroups is the one place hiding is applied, which is what keeps
those answers apart.

The editor asks which vault on the terms the host editor's picker set: while adding
only, hidden where there is one writable vault, and never offered afterwards, because
the two are encrypted under different keys and moving an item is a delete and a
retype. Its parent picker is that vault's alone, for the reason the host editor's
group picker is one level down — a parent in another vault is a level half the key
holders cannot resolve, and their hosts would inherit from nothing. + NEW GROUP
inside an open group departs from NewHost and takes that group's vault rather than
the standing preference: a group made inside another is in its parent's vault by
construction, and answering "inside PLATFORM" with a group elsewhere and no parent
would drop the one thing the button said.

Two smaller things follow from the cards spanning vaults. Dragging a host onto a
group card in another vault is refused with both names, because the write it would
make is exactly the id-nobody-can-resolve the host editor's picker was fixed to
prevent, and treating it as "no group" would unfile a host somebody was plainly
filing. And a group being renamed says its vault in the drawer's header, since the
picker is not drawn for an existing one and renaming a colleague's shelf without
being told whose it is is the edit most worth naming.

The save target is a nullable field behind a property that falls back to the standing
preference. The group name box is bound whether or not anything raised an editor over
it — that is what the desktop's group bar was, and typing a name into it and pressing
ADD is still a way to make a group, which would otherwise have written to no vault
at all.

1575 tests pass, five more than before: a group filed into a shared vault is listed
and renamed there, the editor's picker does not move the keychain screen's, the
parent picker offers only its own vault, a cross-vault drop is refused, and hiding a
vault takes the cards without changing what its hosts dial.

jaap-jan bee6202949 Let a host be moved to another vault
The one thing the host editor's vault picker has always been unable to offer,
and the comment beside it said so: an existing host's vault was not a field
because the two vaults are encrypted under different keys. That is still true.
What changed is that it is no longer a reason to have nothing.

**A move is a copy and a tombstone, and it cannot be anything else.** A payload
is sealed under its vault's key and its AAD binds the vault, the entity id and
the item version, so no edit moves one and no server call could — the server
holds ciphertext it cannot read. What crosses is the plaintext, in this process,
between an unwrap under one key and a seal under another. VaultItemRepository
gained MoveAsync for it, so the three decisions below live in one place with
their reasons rather than being re-derived at each call site.

The item takes a new id. Keeping it would put one entity id in two vaults, and
the item table is keyed on the type and the id rather than on the vault — so the
destination's row and the source's tombstone would be the same row, and the move
would delete what it had just written.

The write comes first and the tombstone second, which decides what an
interruption leaves: a copy in both vaults, visible and deletable, rather than a
tombstone with nothing on the other side. Both are queued rather than sent, so
the window is a crash between two local writes; it is still worth being on the
survivable side of.

Two activity lines rather than one, because that is what the two vaults actually
record. A single "moved" line would have to be written to one of them and would
be missing from the other's history.

**The group and the tags stay behind, and that is the half that makes this
honest.** Both are items of the vault the host is leaving: the editor's group
picker offers one vault's groups and the chips are drawn from one vault's tags.
A host carrying either across would resolve it on the machine that moved it —
groups and tags are resolved over every readable vault — and dangle for everybody
else in the destination. The mover and their colleagues would be looking at two
different hosts. Cleared and reported beats carried and invisible.

The key or password binding is kept, and the difference is not inconsistency.
Those genuinely resolve across vaults — one key on twenty hosts in three vaults
is the arrangement they exist for — so clearing them would take a working host
and make one that cannot connect. What the message does instead is name a
binding that is now outside the destination, because that is precisely what the
other members of it will not be able to resolve.

**It is not in the editor**, on either head: the desktop puts it in the detail
pane's ⋯ menu above the separator Delete sits below, and the phone beside EDIT.
A picker inside the form would move a machine as a side effect of correcting a
port, which is the bug the editor's own vault picker was fenced off to prevent in
the first place. The panel takes the footer as the deletion question does, and
says what will be left behind before the tap rather than after it — on a phone,
where the status line afterwards is one line on a screen somebody has already
navigated away from, that is the only place it reliably gets read.

The phone hides the button where there is nowhere to go rather than offering one
that answers with a refusal; the desktop keeps its menu entry either way, because
a menu that grew and shrank would be a menu whose items move.

One thing found while writing the test and deliberately not changed. The pass
that follows every write on this screen reports what it moved and supersedes the
confirmation — for a save and a delete as much as for a move — so the move's own
sentence is what somebody sees offline. The test asserts it in that state and
says why. Making confirmations survive their own sync pass is a question about
the whole screen rather than about this.

Four places said an item could never be moved, two of them sentences on screen in
both heads. All four now say what is true, including the design gaps document,
where the chevron beside the vault name stays undrawn for a different reason: a
chevron on a subtitle implies an edit, and this is a re-seal, a new id and two
references left behind.

jaap-jan e9cea2ccbc Let a shared vault arrive, a bucket be found, and a vault be deleted
Three things a user reported, one of which was a real bug and one of which was
not the bug it looked like.

**A vault shared with somebody never reached their machine.** The grant was
correct at both ends: the sharing client verified the recipient's key against the
key log and wrapped every generation to it, the server stored it, and /me would
have returned it. Nothing asked. VaultSession.RefreshVaultsAsync — the method
whose own summary says it is "called after a share and on a periodic pass" — had
no caller anywhere in the application, so the vault list was whatever the last
browser sign-in cached. A restart did not help: an offline unlock reads that same
cache. The vault appeared only if the recipient happened to sign in through the
browser again, which is why this looked like sharing being broken rather than
like a list that was never re-read.

So every synchronisation pass now re-reads it, before it syncs. SyncOnceAsync
takes the whole server rather than its sync half for that reason, and the order
matters: a vault admitted by the refresh is one that same pass then pulls, where
the other order would show a newly shared vault as an empty one until the minute
after. The shell is told only when the set actually changed — it rebuilds the tab
strip's vault menu from the session's list, and doing that on every quiet pass
would rebuild a menu once a minute for nothing.

The test needed the fake server to be able to do something no test here had
needed before: hand this account a vault it did not make. ShareVaultWithMe wraps
a real key to the encryption key this account enrolled, so the keyring opens it
exactly as it opens a real colleague's — a helper that filled the field with
bytes would let a vault appear in the list and never prove it could be read.

**Adding an S3 bucket on the desktop works, and could not be found.** The report
was that it is not possible; driving the real XAML headlessly says otherwise —
Keychain, + BUCKET, and the editor saves. What is true is that S3 is where
somebody goes looking, and from there SELECT BUCKET opened a combo box with
nothing in it and no sentence anywhere saying that a bucket is a keychain item.
From where the user was standing that is indistinguishable from an application
with no way to add one.

The empty state now says what a bucket is and offers a button that lands on the
keychain with the editor already open — navigating to the screen and leaving
+ BUCKET to be found among five buttons would be most of the same problem. The
phone gets the sentence and no button: its keychain screen reads and deletes and
edits nothing, so there is no editor to send anybody to, and naming the machine
that has one beats an empty control that reads as a screen still loading.

The keychain screen's layout test grew the two categories it never covered.
Tags and buckets arrived after it was written, and the header strip it measures
is one that has overflowed twice before.

**A vault can now be deleted.** DELETE /api/v1/vaults/{id}, gated on Admin —
the line the rename already drew, for a stronger version of its reason, since
this takes the vault from everybody in it at once. The row is soft-deleted and
every grant to it withdrawn in one write; VaultAccessService filters on the stamp
at both ends, so from that moment the vault is absent from every member's /me and
every call naming it answers 404. Their clients notice on the pass described
above.

The team behind it is archived when it owned nothing else, which is the mirror of
renaming it: a vault made from the vaults screen gets a team named after it that
nobody was ever shown, and leaving that behind would leave a membership list no
screen has a row for. That is a second call rather than one transaction —
archiving is TeamService's, it refuses while a team owns vaults, and it can only
tell that this one no longer does once the deletion is committed. A crash between
the two leaves an empty team: invisible, archivable afterwards, harmless, and a
better failure than a vault that could not be deleted because tidying up after it
did not work.

Two refusals worth stating. The personal vault cannot be deleted at either end:
it is created by enrollment, everything filed nowhere else lives in it, and no
call would make another. And the items are kept — ciphertext behind a vault
nothing will resolve, so deleting them buys no confidentiality while destroying
what an operator undoing a mistake would need.

The client drops the key from the keyring and the row from the cache rather than
waiting for a refresh, so the list is right immediately; the items stay, as they
stay for a vault whose grant was withdrawn, because a copy is on every other
member's machine too and removing these rows would be the client pretending to a
reach it does not have. The confirmation says that out loud before it is
answered. It is the one sentence this screen must not leave implied: deletion is
no more retroactive than revocation is. See ADR 0001.

Desktop only, deliberately. The Android vaults screen offers no rename and no
hand-over either, so adding delete alone there would be the one destructive vault
operation on a screen with no other.

Three places asserted that a vault can never be deleted — TeamService's refusal
message, the TeamNotEmpty problem code, and ADR 0009 — and each now names the
route instead.

jaap-jan a0568d4c35 Merge branch 'main' into the vaults screen, and let it rotate keys too
Main built vault key rotation while this branch was reshaping the screen that
would drive it, so the two met in the same three files. Every other conflict was
textual and resolved by taking both; these are the ones where a decision had to
be made.

**The view model.** Main taught TeamsViewModel three things and this branch had
renamed and rewritten it into VaultsViewModel. All three are ported rather than
dropped, because each is a behaviour rather than wording: adding somebody now
wraps the vault to them on the spot instead of leaving SHARE KEY to be pressed,
removing somebody rotates the vault and hands the new key to whoever is left, and
a share reports how many generations were wrapped. The session calls they reach —
ShareTeamVaultsAsync and RekeyTeamVaultsAsync — are scoped to a membership list
rather than to one vault, and they are called that way here rather than narrowed:
adding somebody is a change to the list, so every vault the list carries is one
they can now fetch. This screen makes lists that carry one vault, so the sentences
name one; where a list carries several, naming them all is the honest report, and
the members section already says the list is shared.

AddMemberAsync ran two lines over the length limit once the sharing was in it, so
the calls behind it moved to AddOrInviteAsync and the three-way refusal to
WhyNobodyCanBeAdded — the command reads as its guards now, which is what it was
before the sharing arrived.

**The tests.** Main's four new cases are ported to the vault-first API, including
the one that matters most: the tampered key log is corrupted *before* the add,
because the add is now a route to a wrap and a test that corrupted it afterwards
would be asserting about the manual route only. SelectingAVault_ListsWhoHoldsAKey
now expects two holders rather than one — main's fake records the creator's own
self-grant, and a key-holder list that omitted it would show the one person who
can certainly open a new vault as somebody who cannot.

**The README.** The limits list is six rather than four or five: main's rotation
entries and this branch's "a vault cannot be deleted" describe different things
and both are true. "The rekey is flagged, never performed" is gone, since it is
now performed, and M3 reads *Done* rather than *Done, except rekey*.

One thing worth writing down that neither side had. An invitation claimed at
sign-in still leaves the key owed, where an add does not: at the moment an
invitation is issued there is no account and no published key to wrap to, and the
claim happens on the invitee's machine, which holds nothing. Manual check 12.1
says so, because a reader who knows adding shares would otherwise read that step
as stale.

1561 tests pass.

jaap-jan 8707629a6c Make the vault the thing you share, and ask a host which one it lives in
The teams screen listed teams that owned vaults, so sharing four servers with two
colleagues meant creating a team, then a vault inside it, then wrapping a key.
Two of those three steps are about a concept nobody arrives wanting. The screen
now lists vaults: naming one creates the membership list that carries it, named
after the vault and owned by you, and members, invitations, roles, hand-over and
key holders all hang off the vault they apply to.

Nothing on the server moved. VaultAccessService still resolves a shared vault
through team_membership and every membership call still names a team id — what
went is the requirement that anybody make one. The split the whole design rests
on is untouched and is still what the screen is built around: adding somebody
authorises the server to serve them, and only a machine holding the key can make
the vault readable. ADR 0009 keeps its decision and gains an addendum recording
which half of it a person is now asked about.

The one place the team resurfaces is a membership list carrying several vaults,
which this screen cannot produce and does not hide: the members section says so,
because "adding somebody here adds them there" is precisely the fact a
vault-shaped screen is in a position to conceal.

Two things left the interface and one arrived. Creating a team is gone, and so is
archiving one — it was only ever possible for a team owning no vaults, and a
screen whose rows are vaults has no row for one, so the button would have been
unreachable or always refused. The endpoint is unchanged and the screen states
the limit instead, since a vault cannot be deleted at all. The exception is a
create whose second call failed: cancelling that form archives the membership
list it left behind, which is a deliberate departure from this client's rule
against tidying up on the user's behalf, made because nothing else can reach it.

What arrived is PUT /api/v1/vaults/{id}. Without it the screen loses its only
editing action, since renaming the team behind a vault is invisible to everybody
who was never shown the team. It is gated on PermissionFlags.Admin — the line
UpdateTeamEndpoint already draws, because a name is what everybody in the vault
sees it called rather than part of its contents — and it renames the owning team
with it when that team carries nothing else, so the row an operator reads and the
name a user says cannot drift apart. The slug never moves, for the reason it does
not move on a team rename. The session edits its cached vault row rather than
replacing it with the response, which deliberately carries no wrapped key.

The host editor now asks which vault a host goes into, beside the name, while
adding and only where there is more than one vault to write to. It is a second
picker rather than the keychain screen's reused, and the two selections are
separate on purpose: that one is a standing preference about where new items go,
this is a field of the host in front of you, and binding both to one selection
would mean a click on the other screen could move a half-typed host. An existing
host is not offered it at all rather than offered it disabled — the two vaults
are encrypted under different keys, so moving an item is a delete and a retype.

That forced a fix worth naming. The group picker was built from the active
vault's groups whatever vault the host was being filed into, so a host put in a
shared vault could be filed under a group only its author can resolve — a
colleague would see it filed under nothing, which is the quietest kind of wrong.
Groups are now kept per vault and the picker follows the vault choice.

Two renames, because the pair they would otherwise have made is a bug farm:
ShellScreen.Vault became Keychain and VaultScreen became KeychainScreen, which is
what the rail has always labelled that screen, leaving Vault for one vault's
contents and Vaults for the vaults themselves. The enum values are unchanged;
NavRail.axaml writes them as x:Static literals.

1536 tests pass, seven more than before. Five are new on the server — the rename
endpoint's success, the team it does and does not take with it, the two refusals
and the empty name — and the client suite gains six and folds four together,
having lost the two about archiving a team.

Two conflicts, and the second is worth recording. main's M4 bullet gained the
Android signing decision while this branch rewrote the M5 line either side of it;
both are kept.

The other is an ADR number collision: two sessions each took 0010, one for vault
key rotation and one for Android distribution, and both are now on main. ADR
numbers are identifiers — "see ADR 0010" appears in code comments as well as in
prose — so leaving two would make every such reference ambiguous. The rotation
ADR landed first and is referenced from crypto.md, the gaps document, ADR 0009
and the sync code; the Android one is referenced from README and android-port.md.
So the later and cheaper one moves: 0010-android-distribution.md is now ADR 0011,
with its title and both references updated. Nothing about either decision changes.

jaap-jan 5d447da532 Take a rotated vault's contents onto the new key as well
Rotating a vault re-keyed the vault and not its contents, which was the deal
struck last time: everything already stored stayed sealed under the generation it
was written with, every remaining member kept the older keys, and the guarantee
was narrowed to "nothing written from now on". That left one gap worth closing —
somebody who walked off with the old key could still open old ciphertext they
later got hold of — and the reason it was safe to defer is the reason it was
cheap to add. A vault at mixed generations reads perfectly well, so the pass that
moves items across can stop half way and be run again.

VaultResealer walks the vault and rewrites each item as an ordinary upsert
against the version the server holds. It never decodes the plaintext: an item is
opened and the same bytes are sealed again under a fresh data key, so an item
written by a newer client crosses a rotation untouched rather than being
re-encoded through this build's codec and quietly losing the fields this build
has no concept of. It also means nothing in the pass knows what an item is, which
is why one loop covers every type including the ones added after it. A conflict
is counted and skipped rather than merged — there is nothing to merge, since no
content changes — and the next pass picks the item up at the version the other
client left.

The half that a pass over stored items cannot see is a change queued before the
rotation and pushed after it, which would put a brand-new item into the vault
under the key the person who just left still holds. So the push path re-seals a
stale payload as it dispatches it, writing the revision back to the outbox first
so that a retry sends the same bytes rather than a fresh envelope. Between the
two, nothing reaches the server under a superseded generation at all. Queued
items are therefore deliberately left alone by the pass: rewriting one there
would overwrite the user's unpushed work with the version the server holds, which
is the one thing a re-keying pass must never do.

Removal runs it last, after a sync — a mirror that is behind produces a batch of
conflicts instead of a re-sealed vault — and the status line distinguishes the two
guarantees, because they are not the same: a vault fully re-sealed is closed to
the person who left, and one with items outstanding is closed only to what
happens next.

Six tests, and three mutations run against them: making the re-seal return the
payload unchanged fails five of the six, making the push path skip re-sealing
fails the queued-edit test and only that one, and counting conflicts as applied
fails the write-elsewhere test. One of the six was wrong before it was right — it
modelled a third-party write by re-pushing an existing payload at a bumped
version, which no real client would do, and it took reading the AAD to see that
the test was lying rather than the code.

jaap-jan ebb88c8ae4 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.

jaap-jan 2a56ae3efb Put a host inside the group it is filed under, rather than beside it
The group cards were headings with a navigation gesture bolted on. Opening one
narrowed the grid to its hosts, but the level above already held every host in
the keychain — so a card could only ever subtract, filing something changed
nothing but a chip, and a keychain with forty machines was forty cards however
carefully anybody had arranged them. The trail said ALL HOSTS and meant it.

So the grid holds one level of the tree, the way a directory pane holds one
directory. A host filed under a group is inside that group and is not also on
the screen the group's card sits on; the outermost level is what nothing has
been filed into. A group is a place now, and the cards, the trail and the drop
target were already the vocabulary for saying so.

The find box is the exception and had to be one. Typed into, it searches the
open group and everything under it, which from the outermost level is every
machine in the keychain. A box scoped to the level it was typed on would answer
"no host matches that" about a host this keychain has got, and finding a machine
without first remembering where it was filed is most of what the box is for.
The accent chip on a card is what tells a searched-up host from one that lives
at this level.

Two things came free with the change and are handled rather than left.

The phone would have broken. Its list binds SidebarRows, which was a projection
over VisibleHosts, and it has no group cards and nowhere to open one into — so
level-scoping would have left it drawing only the hosts nobody had filed.
RebuildSidebarRows takes its own pass over the hosts now, narrowed by the vault
switches and the box and by nothing else, which is the whole tree flattened
under headings: exactly what it drew before.

And anything created inside a group disappeared the moment it was saved. The
host editor opens on the group the screen is about rather than only on a
selected card, and + NEW GROUP defaults its parent to the group that is open.
Deliberately not the selected card there: a highlighted card is what EDIT and
DELETE are aimed at, and reading it as "and the next group goes inside it" would
nest one because somebody had clicked something. The host editor takes both
because it always took the selection, and its picker shows the answer before
anything is written.

Dropping a host on a group card now takes the card off the grid, and the
selection goes with it — Connect, Edit and Delete all read that property and
none of them should be aimed at a card that has left the screen. The status line
is what says where it went, which is why the manual check now asks for it to be
read. Coming back out through the editor lands the host on this level again, and
there the selection survives.

An empty grid has two more things it can say: that every host is filed away,
which the level-at-a-time grid made reachable and which is not the same sentence
as "there are none", and that nothing under this group matches what was typed —
with ALL HOSTS named as the way to widen it.

Not changed, and next door: a group card counts the hosts filed directly under
it, so a group holding only subgroups reads "0 hosts". That was already true and
is more visible now that its subgroups' hosts are not spilled onto the level
above.

1522 tests pass. Four are new — the level rule and the phone's flat list
asserted together, the box reaching two levels down, the all-filed sentence, and
where a host and a group made inside a group end up. MovingAHostToAGroup was
asserting the old outcome and is rewritten rather than adjusted: it held that
the host stayed selected, and what it holds now is that the host leaves the
level it came from.

jaap-jan d5b1a73182 Move the keys when a membership changes, not just the flag
Adding somebody to a team granted them nothing readable and removing them
rotated nothing. Both were honest — the interface said so in as many words — and
both left the actual work to a button somebody had to remember to press, on a
machine that happened to hold the key. Adding now wraps every team vault this
machine can open to the new member, and removing revokes their grants and moves
each of those vaults to a fresh key that goes to whoever is left.

The rotation is where the design had to be decided rather than written. A vault
key is per generation and an item carries the generation it was sealed under, so
advancing the vault and withdrawing the old grants would make everything already
stored unreadable to everybody, including whoever pressed the button. So earlier
grants are kept: a member holds one per generation, /me serves them as
PriorKeyWraps, and VaultKeyring holds a key per generation — the newest for
writing, the item's own for reading, chosen per item on every read path. Sharing
issues one grant per generation held, because a recipient handed only the current
key would open the vault to find most of it undecryptable; revocation takes every
generation, because leaving the history behind leaves them able to read
everything written before the rotation.

The bump itself is one server transaction. POST /vaults/{id}/rekey must name
exactly current + 1 and the vault's xmin token makes that binding, so two admins
rotating at once do not both walk away believing they succeeded — the second is
refused and told to read the vault again. The server contributes the moment and
no cryptography: it cannot generate the key, cannot tell that the one it is
handed differs from the old one, and checks that the caller held the old one the
only way it can, by requiring a live grant at the current generation.

What this does not do is re-encrypt what is already stored, and the product says
so rather than the reassuring version: everything written from the rotation
onwards is unreadable to the person who left, and nothing about the past changes.
That half is deferred and is safe to add incrementally precisely because a vault
at mixed generations stays readable. ADR 0010 records the alternatives — revoking
the old grants, chaining each key under its successor, re-sealing every item in
one request against a server that caps a push at 500 operations — and why each
was rejected.

Two things fell out of the change rather than being asked for. The grant listing
would have shown a member once per generation, so it now returns one row per
holder carrying the best key they hold, which is what makes a row below the
vault's generation mean "still owed the new key". And MarkUnreadable gives up the
write target as well as reporting: a client whose vault was rotated elsewhere
would otherwise have gone on sealing items under its superseded key — readable to
its author, unreadable to everybody else, with nothing to show for it.

jaap-jan 7b7fd7b2ef Make a vault the thing you create, and let a window set one aside
Everything a shared vault needs was already here and arranged the wrong way
round. A vault has to belong to a team, so creating one meant going to the teams
screen, founding an organisation, and only then adding a vault to it — which the
NEW VAULT button named after the team, so a team with three of them held three
vaults called the same thing and nothing told them apart. Somebody who wants to
share four servers with two colleagues is not asking to found anything.

So the form asks for a name and nothing else. The team is derived from it, slug
included, and created with this account as its owner; the vault goes inside; and
the members, roles, invitations and key holders that hang off a team are all on
screen the moment it exists. The tab strip's New vault entry lands there with the
new vault selected, which is where the next thing anybody wants to do already is.

That is two calls, and the first can succeed alone. When it does the team is
kept: the id is minted once into pendingVaultTeamId, so pressing CREATE again
resends the identical create — which the server treats as the same team — and
retries the vault, and the message says all of that rather than "creating the
vault failed". Archiving the orphan instead would be a client deleting something
on the user's behalf because a later step failed, which is the kind of tidying
that eventually archives a team somebody has just been added to. A slug taken by
somebody else is retried once with a disambiguated one and never in a loop; a
name with no a-z or 0-9 anywhere in it falls back to the team's own id rather
than to a refusal pointing at a field nobody was shown.

The other half is the caret beside Vaults. Being in four teams means four teams'
machines in front of you all day, and the answer is a switch per vault rather
than four sign-ins. Switching one off takes its hosts, groups, keys and pins off
the screens that list them and does nothing else: it still syncs, its key stays
in the keyring, it stays choosable as somewhere to file a new item, and a shown
host that authenticates with a key filed in it still connects. That last one is
what shaped the design. TryBuildAuthentication resolves a binding out of the
keychain's typed list and a cross-vault binding is legal, so filtering the reload
loops — the obvious implementation — would have turned a preference about reading
into an outage. Only the projections a person reads consult IsVaultShown; every
Reload*Async stays whole, including the dialled-endpoint set that decides which
pins are described as unused, because that is a hint which invites deleting
trust.

Snippets, logs and buckets needed no code and the comment says so out loud: all
three read ActiveVaultId alone, and the personal vault is drawn in the menu
ticked and cannot be switched off — it is the active vault, the group and tag
editors' target, and the save picker's fallback, so hiding it would empty half
the application rather than filter it.

The preference is a column on the cache's vault row, which is what makes it
survive both a relaunch and the /me refresh that runs every minute: Apply does
not touch it, deliberately, because the server has never been told which vaults
this machine is showing. It is in the encrypted cache rather than settings.json
because it is a list of vault ids and that file's own doc comment says what may
go in it. VaultSession cannot see the type at all — ReadableVaults is what the
sync loop walks, and a filter reaching it would be a vault that quietly stopped
syncing, found out weeks later from a host that was never there.

The strip's note refusing a MenuFlyout stands and is unchanged. This flyout
sidesteps the question rather than answering it: the handler selects the Vaults
tab first, which collapses the renderer, so nothing native is under the popup by
the time it opens — the move QuickConnect already makes. A headless test asserts
that ordering, which is as far as headless can go with no native window, and
manual check 1.6 is the other half.

The phone is out of scope on purpose: it has no tab strip and its teams screen's
vault section is read-only. The plumbing is in Client.Shell, so it can adopt this
later; until then nothing there is ever hidden, which is today's behaviour.

1514 tests pass. Fifteen are new in VaultVisibilityTests, and the ones worth
naming are the guards: a hidden vault still syncs, still holds keys that
authenticate hosts on screen, still appears in the save picker, and still counts
towards which pins nothing dials.

Not fixed, and noted here because it is next door: VaultGrantService's team-vault
create refuses a taken vault id rather than returning the existing vault, while
VaultSharing's own remark claims a create whose response was lost is safe to
resend. A lost 200 therefore leaves a vault whose key the client's catch already
zeroed, openable by nobody.

ci / build and test (push) Successful in 1m30s
ci / android head (push) Failing after 5s
ci / api image (push) Successful in 33s
ADD MEMBER quietly issued an invitation instead of adding anybody, for everyone
who had signed in here and not yet enrolled. The screen told them that address
had no account, the members list did not change, and the person only actually
joined on the next hourly sweep.

The client decided whether an address had an account by asking the public-key
directory, and the directory answers a narrower question than that. It drops
every account with no current key — deliberately, because an entry exists to be
wrapped to and one carrying no key is a check a caller forgets exactly once. An
account exists from its owner's first authenticated request and publishes
nothing until they choose a passphrase on their own machine, so every account is
missing from the directory for that whole window and some indefinitely. A miss
there is not an absent account, and reading it as one was the bug.

The server would have taken the add. TeamService.AddMemberAsync only requires
the account row, and TeamMemberSummary.IsEnrolled exists precisely so a member
with no key can be listed — added on Monday, enrolled on Tuesday. The client
never asked.

So the directory is still asked first and the miss is retried as an add by
address, and only a server saying there is no such account reaches the
invitation. AddTeamMemberRequest gained an Email used when UserId is empty. The
lookup-first ordering is kept because it is load-bearing for sharing and not for
this: the key verified before a vault key is wrapped is the one the lookup
returned, and nothing is wrapped by adding somebody. That is why resolving the
address server-side is safe here and would not be there.

NoSuchAccount is its own code rather than folded into InvalidTeam, because it is
the one add failure the caller can act on unprompted — there is nobody to add,
so invite them — and a code shared with a rejected role would leave them
guessing which had happened. It does answer whether an address has an account
here, which CreateTeamInvitationRequest deliberately does not. That is the
property traded for the fix; the exposure is bounded by the admin check the add
already needed, and it is the same fact the member list shows a moment later.
Adding by a user id that does not exist now answers 404 no-such-account rather
than 400 invalid-team, and nothing depended on the old pairing.

The two silent returns are gone. Offline and no-team-selected set nothing and
returned, so those failures were visible only as a flicker of the busy flag —
which reads as a button that does nothing at all. The success line reads the
enrollment flag too, because pointing an unenrolled member at SHARE KEY is
pointing at a button that will refuse; their row already says it holds no key.

Why nothing caught it. FakeVaultServer had one list, so it could not tell an
account that does not exist from one that exists and has not enrolled — the
distinction this whole path turns on — and every account it knew was enrolled by
construction. It grows an accounts list beside the directory and reports
IsEnrolled from whether the directory has them, rather than hardcoding true. The
regression test asserts Invitations is empty, which is what fails against the
old behaviour. Four tests: that pair in the shell suite, and in the API suite an
unenrolled account added by address after its own directory lookup comes back
empty, and an unknown address refused under the new code. 1495 tests pass.

jaap-jan a2c56de1f2 Read the selected team once per reload, so its owner is listed once
Creating a team drew its owner twice. ReloadAsync rebuilds the team list and
then reselects, and the selection handler answers that assignment by starting
its own read of the members, invitations and vaults — while ReloadAsync is
awaiting a read of exactly the same thing. Both clear the collections up front
and both append when their round trip answers, so everything below the team list
was drawn twice. On a team nobody has been added to yet, whose only member is its
owner, that read as the owner being in the team twice.

The rows are records, so the reselect only raises a change when something about
the team has actually moved — which is every reload that follows a change:
creating a team, adding a member, renaming one. A plain refresh looked fine, and
the screen doubled precisely after the acts people come to this screen to
perform.

isReselecting suppresses the handler for the length of the assignment rather
than deduplicating rows afterwards, because only one of the two reads is
awaited. A command that reloads and then reads Members has to be looking at the
reload's own read and not at a fire-and-forget one that may not have answered.

The generation counter is the other half, and it is a different bug with the
same cause: selecting a second team before the first has answered leaves two
reads in flight against the same collections and nothing decides which wins, so
team A's members could land in the list under team B's name. A superseded read
now drops its answer instead of appending it.

Why nothing caught this. The fake server answers from memory, so every read
completes before the next begins and the appends can never interleave — the
duplicate needs a round trip to hold two reads open at once. FakeVaultServer
grows a MemberReadGate for that, and the new test holds a read open and counts
the reads in flight, which is the only moment a second one is distinguishable
from the first. It fails against the old behaviour with two. 237 tests pass in
the app suite and 83 in the layout suite.

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 61139bd469 Move the SFTP and S3 connection into the right-hand pane
THE CONNECT BAR IS GONE. It was a 44-pixel strip across the top of the file
screen holding a heading, a picker, a password box and a button — chrome
spanning both panes in order to configure one of them, drawn at full width
whether or not anything was ever going to be connected. Underneath it sat a
pane that was empty for exactly the same reason, saying so in a sentence
nobody had to be told twice.

So the pane says it instead. Disconnected, the right-hand half is an invitation
where the listing would be: what the screen is for, what pressing the button
costs, and one thing to press. SELECT HOST opens the picker in place — the same
combo, the same password box, the same CONNECT — and the sentence and the
button go away with it, because by then they have been read or they have not.

Two steps rather than a picker sitting open, and that is not decoration. The
reason the pane is empty is the question, and a combo box in the middle of it
is a form with no question above it. The two steps also keep the panel inside
its budget, which is the pane's height less whatever the queue has taken — 268
pixels with three transfers on it. Neither shape reaches the floor, and the
layout suite measures both.

IsChoosingRemote is cleared by everything that changes what the picker would be
picking: connecting, disconnecting, moving between the SFTP and S3 tabs, and
losing the vault. The last two are the ones that would rot quietly — a picker
surviving a hop to the other tab offers hosts on a screen showing buckets, and
one surviving a lock offers a list that has just been emptied because its rows
carried decrypted secrets. CANCEL takes the typed password with it, which is a
secret nobody asked to keep.

WHERE THE TWO CONNECTED FACTS WENT. The address chip and DISCONNECT are a strip
of their own inside the remote pane, above the listing — not three more cells in
the header beside UP, REFRESH and DELETE. That pane is 381 pixels wide at the
window's minimum and a fourth control in that row would have pushed one of the
three off the edge; the number is written into the markup so the next thing
added to either row is measured against it rather than tried.

The status line did not fit there either. What is left after a 170-pixel address
and a DISCONNECT is about eighty pixels, which turns every sentence into its
first word and an ellipsis, so while a session is open it is in the queue's own
strip at the foot of the screen, which spans the window. The other half of the
time it is inside the invitation, beside the button that provoked it. One home
in each state rather than two homes in one and none in the other.

The header label reads HOST or BUCKET now, which is the only thing on the screen
naming the kind — the bar that printed SFTP or S3 is gone and the tab in the
strip says it either way, whether or not this screen is showing.

The opening status text was "Choose a host and connect to browse its files",
which the invitation now says in a heading, a sentence and a button. It is
"Nothing is open yet.": a state rather than an instruction. That string is
shared with the phone, where it still reads correctly under the picker card
that head shows directly.

Desktop only, and the phone is unchanged rather than merely untouched. Its
FilesScreen is one pane at a time, so the picker *is* what it shows before a
connection exists; it binds none of the new members.

Four tests. Three in the layout suite — the picker open over a full queue, which
is the tall shape and the one that has to be measured with the panes at their
least; the bucket picker, which is a row shorter because an object store has
nothing to type; and a session open with a long enough address to prove the chip
gives way before DISCONNECT does. The fourth is the picker's lifecycle in
ShellFlowTests, over all four things that put it away. 302 tests pass across the
two suites.

jaap-jan f9d08b738c Take the group headings out of the host grid, and drop onto a group card
A first group turned the wrap of host cards into an accordion: SidebarRows
interleaves a full-width fold-away heading — chevron, name, count — between the
cards, and in a grid that reads as a dropdown somebody left open. The desktop
grid binds VisibleHosts now. The headings and the fold stay for the phone, whose
list has no room for the row of group cards the desktop draws above the grid.

What a heading said, the card says: HostRowViewModel.GroupLabel, resolved once
per reload like the tag names, drawn as an accent chip and absent from a host in
no group — or in one that has been deleted, which is the same thing to look at.

What a heading also was is the drop target, and that moves to the group cards.
Two things go with it. A host dropped onto another host card used to be filed
beside it, which was legible while a heading named the band of cards it landed
in and is guesswork now; it is refused. And UNGROUPED was how a host was dragged
back out of a group; the way out is the picker in its own editor, which is the
one place "no group" can be said in words.

A drag held at either edge of the grid scrolls it. Without that the gesture only
works for whoever can see both ends of it: the group cards are the first thing in
the scroller, the host may be the fortieth card down, and a drag cannot use the
wheel. A step per drag event rather than a timer, so it follows the pointer and
stops when it stops.

The two heading-shaped tests are replaced. TheHostsGridHoldsCardsAndNoGroupHeadings
asserts the grid's contents rather than only measuring them, because a heading
that came back would lay out perfectly cleanly. TheGroupCardsAreWhatAcceptsADroppedHost
raises a real DragOver over both kinds of card and checks the effects and the
mark — the nearest a headless test gets to a gesture no headless test can
synthesise. manual-checks 3.1-3.2 and 7.6-7.9 follow.

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).
2026-08-03 15:35:49 +02:00
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 7e4e068aab Merge main into the teams branch
Two conflicts, and both were two people counting the same things differently
rather than disagreeing about what the code should do.

PhoneShell's header comment. The branch made "the five hub screens"
numberless, because TEAMS made it six and a number in that sentence had
already gone stale once. Main corrected "three destinations" to "two" in the
same sentence, because giving a shell the whole phone took the terminal out of
the set the header is drawn on. Both are right and neither noticed the other:
the header now stays on the hub's screens and on the two top-level
destinations, which is Hosts and Keychain.

The manual checks. Both sides appended a Phase 10 — main added the software
keyboard and the phone's terminal surface as 10 and 11, the branch added
Teams. Nothing about them overlaps, so the resolution is to keep all three in
the order they were written and renumber Teams to Phase 12, its subsections
and the one cross-reference inside 12.1 with it. Main's two phases keep the
numbers they already carry in its history, since renumbering those would move
headings somebody may already have linked to.

Everything else merged without a conflict, and the two places worth checking
afterwards both held: IsMoreSurface and the first case of
PhoneShell.OnBackRequested each kept ShellScreen.Team alongside main's edits.
Those two are one fact in two places, so a merge that dropped Team from either
would have trapped the user on the teams screen with the MORE tab dark.

Verified after resolving: solution builds with no errors and no new warnings,
the Android head builds, and every suite passes — App 214, Layout 73, Api 162,
Infrastructure 34, Contracts 25, Session 54. App gained the three shell-flow
tests main brought with it.

jaap-jan b86ff6158b Keep the password that just worked, so the host stops asking for it
The vault has held credentials and host bindings since they landed, and the
only route from a typed password into one ran through two screens: add a
password under Keychain, open the host, bind it. The password box's own tooltip
instructed people to do exactly that by hand — which means typing the secret a
second time, into a screen that has no idea which host it is for, while the
screen that does have the password is the one being left behind. A tick beside
the box does it in one step.

What it produces is an ordinary CredentialSecret, named after the host, bound
through CredentialId with AsksForPassword cleared beside it. That is the whole
reason nothing else here had to change: it syncs, it merges, it appears in the
keychain, it can be renamed and deleted, and it can be bound to the other
nineteen machines that share the account. A password field on HostSecret would
have been a payload schema bump, a fourth place a secret lives, and a copy per
host to rotate and forget.

It waits for a handshake the remote accepted, and that is not caution for its
own sake. Binding on the keystroke would store whatever was in the box —
including the typo about to be refused — and the host would then stop asking,
leaving a machine nobody can connect to until they work out that the keychain
is where the wrong password now lives. For the same reason the password is read
from the credential as dialled rather than from the box, which stays typeable
throughout a handshake.

Off by default, because the typed box exists precisely for the passwords that
should not be in a synchronised vault — a one-off on a machine somebody will
never open again. The credential is written into the host's own vault rather
than the active one: in the personal vault, bound to a team's host, it would be
a binding every other member can see and none of them can resolve.

One thing is given up knowingly. The confirmation naming where the password
went is replaced a moment later by the auto-sync's own count, exactly as
SaveHostAsync's "Saved 'x'" is; this follows that rather than becoming the one
write that suppresses a sync line. The feedback that lasts is the row answering
"credential" and the box disappearing — which is also the only way to store a
password on the phone at all, since that head lists credentials but has never
had an editor to create one in.

jaap-jan 80ae586fc4 Give a shell the whole phone, and one bar to leave it by
A connected phone was drawing five rows of chrome around the thing the user
opened it for. The vault header at 56, the terminal's own tab strip at 52, a
connection line at 36, the shells strip at 46 and the four-entry bottom bar at
64: at 360dp that is about a third of the display, and every row of it was
about somewhere the user was not. What replaces them is one 52-pixel bar drawn
by the surface itself — back on the left, the session pills, and a `+` across
from them — and then the terminal.

Three of those rows belong to `PhoneShell` and each is now bound on
`IsShowingPages`. That is the same question asked once rather than three
conditions that could drift: the surface is either a page or a terminal, and
these are the chrome a page has. The header needed a wrapper because Avalonia's
bindings have no "and" and it already had a condition of its own; the strip
needed one for the same reason. The bottom bar had none and is bound directly.

The back arrow goes to the page the terminal was opened over rather than to
Hosts by name, because the system back gesture already picks that and an arrow
landing somewhere else would be the second of two answers to one question. The
bar's `+` raises a sheet offering the three connections this application can
make — a shell, a host's files over SFTP, a bucket — since SFTP and S3 used to
be two taps through the bottom bar's MORE and the bar is not on screen here. A
control that replaced it and led to one of the three would have quietly removed
the other two.

Two things moved rather than being dropped. The text-size buttons are pinned at
the right-hand end of the accessory key row, outside its scroller: the
connection line existed to keep them from scrolling out of reach, and being
outside the scroller answers that argument rather than abandoning it. The
dialled address moved onto the connecting card, which is the moment it is worth
reading — what is being connected to, before anything has answered — and after
that the shell's own prompt says it more accurately than a header derived from
the keychain ever did.

The sheet collapses the renderer rather than covering it. Whether Android's
`WebView` composites above Avalonia content the way Win32's child window does is
still unverified — `docs/android-port.md` has said so since the port — so this
follows the desktop's palette and gives up the rectangle outright, which is
correct under either answer. It collapses `IsTerminalShowing` and not
`IsTerminalSurface`, because the bar the sheet was raised from is part of that
surface and dropping it would take the bar, the tabs and the whole arrangement
with it, leaving the sheet floating over the page underneath.

`OnSurfaceChanged` is the one place the flag is lowered, and that is the load-
bearing half. Every way out of a terminal ends there — a destination, the files
screen, the palette connecting to a host, closing the last tab, a lock — and
each of them would otherwise leave a sheet set over a page. Not merely untidy:
the flag holds the renderer blank, so the next return to the terminal would
draw the menu again over a rectangle kept blank by it. Opening is refused off
the terminal surface for the same reason from the other direction.

The back gesture gains a guard above the switch, in the shape of the editor
guard that arrived with the phone's `+`. It is nearer than any of them: with no
header and no bottom bar, while the menu is up that gesture is the only way off
it other than the scrim and CANCEL.

The bottom bar's Terminal entry lost its `IsCurrent` binding. The bar is
collapsed on that surface, so the binding could only ever be read as false, and
a rule about a state the control cannot be in is a claim that it can.

Three tests in `ShellFlowTests`, which is where shared state-machine behaviour
for this head goes: the collapse and its recovery, the refusal to open over a
page, and the sheet lowering both by a menu entry and by a route it was never
wired to. Everything visual needs a device, so it is phase 11 of
`docs/manual-checks.md` — and 11.2 is the check that would finally settle the
compositing question this head has carried as unverified since the port.

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.

The default was split on DEBUG so a clone would offer localhost and only an

launches from enrolling a device against production. It also meant the address

2026-08-03 14:27:01 +02:00
jaap-janandClaude Opus 5 16e0051e89 Draw the tags that have been storable and invisible since the domain landed
ci / build and test (push) Successful in 1m22s
ci / android head (push) Failing after 5s
ci / api image (push) Successful in 52s
`Tag` has been a full item kind for three commits — a table, a migration, a
codec, a merge, a cipher — and `HostSecret.TagIds` has merged per tag so two
people tagging one host both keep theirs. Nothing drew a chip. The tags a
client could store were ones nothing here could see.

Chips on host rows, both heads, from names resolved through the tag list rather
than ids: a tag that does not resolve is left out rather than drawn, because it
means the tag was deleted elsewhere or belongs to a vault this session cannot
read, and a host with one chip fewer is the honest answer where a host wearing
a GUID is not. The id stays on the host, so the chip comes back if the tag does.

The picker is chips that toggle, matching the chips on the row behind it. A
list of names to tick would make the user match an entry to a chip they can see
two inches away. The box under it creates a tag and puts it on straight away,
because that is when a tag is usually wanted — while tagging a host and finding
it does not exist yet. Unlike every other field in that editor it writes to the
keychain immediately, since a host can only name an id that exists; cancelling
therefore leaves the tag behind, which is honest rather than hidden. A name
that already exists is used rather than repeated: two tags called "staging" are
storable and must stay storable, because two people creating one offline is how
it happens, but typing it into a box beside a chip of the same name is a slip.

Renaming and deleting needed a home, or the picker fills with names nobody uses
and never empties. That home is a TAGS category on the keychain screen, where
every other item kind is managed — and renaming is the whole reason a tag is an
item rather than a string repeated inside twenty payloads: it is one write, and
no host is touched. The delete confirmation counts the hosts wearing it, which
is the difference between a tidy-up and losing a filter somebody relies on.

The desktop host editor now scrolls, and that is not a tidy-up. A picker's
height is a chip per tag in the keychain, wrapped, so somebody with fifteen
tags has an editor half again as tall as somebody with three; no fixed height
holds that, and trimming other fields to buy room only moves the failure to
whoever has sixteen. The layout suite caught it the moment its seeder grew tags
— which is why the seeder now creates ten rather than three, enough to drive
the pane onto its cap so the capped shape is what gets measured rather than one
no real keychain produces. The cost is named where it is paid: the harness
skips anything inside a ScrollViewer, so from here it certifies that pane fits
the column rather than that every field in it does.

Two smaller things fell out. Five buttons overflowed the keychain header by a
few pixels, so GENERATE lost the word KEY — its tooltip carries what the word
did. And TotalItemCount had been counting keys and credentials while ALL showed
four kinds; it counts all five now, because a number under a chip that
disagrees with the rows it opens is worse than no number.

An adversarial review of this change found two defects it had introduced, both
green against the full suite. NewTag filed into the "new items go to" picker
while the tag list only ever holds the active vault's — so with a team vault
selected a tag would be created, queued for push, reported as added, and then
invisible, with no row, no count, no picker entry and nothing able to rename or
delete it, because there is no active-vault switcher to go and find it with.
The comment on the host editor's own create path states that exact rule; this
was the one place that broke it, and NewObjectStore, whose list is likewise
active-vault-only, already ignored the picker. And the tag editor was the only
one of five that did not disarm a pending deletion when it opened, so arming a
key's deletion and then pressing + TAG left a live DELETE for an item the user
was no longer looking at, directly above the boxes they were typing into. Both
are fixed, both have a test, and the first was checked against the broken
version before being kept.

The same review caught a doc comment that had been inserted between
SnippetRowViewModel's summary and its declaration, silently taking it over.

Verified by the whole suite on a clean build: 1413 tests over nineteen
projects, none failing. Both heads build. The rectangles the layout suite
cannot reach are phase 9 of docs/manual-checks.md.

jaap-janandClaude Opus 5 4925dcf179 Give the phone the + it was promised, and the editors behind it
Steps 5 and 6 of docs/adding-hosts-on-the-phone.md, which finishes it. The
phone can now put things in a keychain rather than only read one.

The floating + arrives three designs after it was first asked for. It was
refused twice on the honest grounds that it would open an editor this head had
not got — and that stopped being true when steps 1 to 4 landed. It raises a
sheet rather than a form, because "add" on this screen has been two operations
since groups existed: a host, or a group to file hosts under.

Both editors are cards in the list's own row, swapped for the list rather than
stacked over it, following SnippetsScreen and for the reason written there: a
form on top of the list hides what it is about. There is still no dialog and no
editor screen anywhere on this head. The port and username boxes may be left
empty, and the greyed text inside each is what the host will actually use —
following the group picker as it moves, so the form says what leaving a box
blank will do rather than making it a guess.

The back gesture gains a guard above the switch rather than a case inside it.
An editor is not a screen and has no entry there, and it is strictly nearer:
the sheet sits over the editor's own screen, so back lowers whatever is topmost
before it considers moving between screens.

A group editor needs a way in, and the phone draws no groups panel — so the
heading in the host list gains a pencil. A + that adds groups with no way to
correct one is the same strange thing to ship as one that adds hosts with no
way to correct one, and worse: a group's defaults are what every host beneath
it falls back to.

Scouting step 6 turned up a bug worth more than the prose it was looking for.
ReloadGroupsAsync read the active vault alone, which was a cosmetic limitation
while a group carried only a name — a teammate's host showed under UNGROUPED
and nothing else was lost. Since a group began lending a port, a username and a
binding, the same omission silently dropped all three: that host would dial 22
as nobody while the machine is on 2222 as deploy, with nothing on screen saying
why. The resolution map now spans every readable vault. The editable list stays
narrow, because a row shown across vaults needs a vault id for rename and
delete and two vaults may hold groups with one name — but the map needs none of
that, since it is only ever asked what an id says.

An adversarial review of this change found something I had written a comment
denying. The + was a child of the outer Panel rather than of the list's row, so
it anchored to the bottom of the screen and sat squarely over the new EDIT
button and the lower edge of CONNECT — and because a Panel hit-tests its
last-declared child first, tapping the right end of EDIT would have raised the
add sheet. The comment beside it claimed it was in the list's row precisely so
that could not happen, and manual-checks 8.1 names that exact failure. It is in
Grid.Row 2 now. The same pass caught a connect bar that was disabled rather
than hidden while its own comment said hidden, a scrim that would have flashed
its default pressed chrome across the screen, a fab comment claiming an accent
fill no other button had when Button.primary has it, and a back-gesture remark
naming two view-model properties that do not exist anywhere in the repo.

That last one came from this plan, which invented IsVaultsSurface and
IsConnectionsSurface, and pointed step 6 at a ConnectionsScreen.axaml that has
never existed. Both are corrected in the plan rather than quietly worked
around, along with a fourth "groups are flat" site in README.md that step 1
missed.

The phone's rectangles are not measurable and structurally never will be: the
layout suite is net10.0, the Android head is net10.0-android, and Avalonia's
application is a one-shot process global — so a second head cannot share the
process even if the reference were possible. Everything the sheet and both
editors bind to is shared and is tested headlessly here; the pixels go to
docs/manual-checks.md phase 8, nine checks, which is where this project already
sends what it cannot assert.

Tags remain the one thing asked for that did not ship. Tag is a full item kind
and TagIds merges, encodes and resolves, but no screen draws a chip or offers
to add one, so the tags a client can store are ones nothing here can see. Both
editors carry the set through a save untouched so a client that can set them
does not lose them. Recorded as half-shipped in docs/design-import-gaps.md
rather than quietly left out.

Verified by the whole suite: 1402 tests over nineteen projects, none failing.
Both heads build. Nothing seen on a display — phase 8 is what that costs.

jaap-janandClaude Opus 5 b7335743d9 Make a host take what its group lends it, everywhere it is read
Step 4 of docs/adding-hosts-on-the-phone.md. The domain could resolve a host
against its groups; nothing asked it to. This is the wiring, and it is mostly
one change repeated: read the resolved host, not the stored one.

TryBuildAuthentication and TryBuildConnectionRequest now take the resolved
value beside the stored one, which is where group context was being lost. It
is the only authentication resolution in the product — both heads and both
transports come through it — so a host inheriting its binding would otherwise
have been offered a password prompt on every screen at once. The
credential-username fallback becomes three levels, and Complete still refuses
an empty username, but now only after the chain has been walked; refusing
before it would refuse exactly the hosts inheritance exists to serve.

HostRowViewModel carries its ResolvedHost, resolved once when the list is
built. Address, Authentication and Dialled read it, so a row cannot disagree
with itself about what it dials — and MainWindowViewModel.Rank searches
Address, so a host inheriting 2222 that displayed 22 would have been
unfindable by the port it actually answers on.

HostsBoundTo counts over the resolved binding, which is the difference between
a warning and a silence: a key bound once on a group and inherited by twenty
hosts named nobody, would have been deleted, and would then have refused all
twenty at connect time.

HostFields.From is answered by a refusal rather than by threading a group list
through the sync engine. A relay host may not inherit its port. The reason is
stronger than the convenience: a plaintext column is a derived duplicate the
client supplies when it pushes *this* host, so an inherited port would make it
depend on another item — editing a group would change what the relay dials for
every host beneath it, except that nothing re-pushes those hosts, so the server
would keep dialling the old port until each was next touched for some unrelated
reason. A stale wire on the relay path connects the user to the wrong service.

The editor distinguishes unset from explicit in both directions. An empty port
box means "take the group's" and shows what that will be as a placeholder,
following the group picker as it moves — a pre-filled 2222 would have been
indistinguishable from one the user typed, and saving would have pinned it. The
authentication picker gains a fourth entry, offered only to a host in a group,
because for an ungrouped host it would behave exactly like the first.

Which found a real defect while the tests were being written. Filing an
ungrouped host into a group silently pinned it to a typed password: the picker
had no "Inherit" entry when it opened, so it sat on "Password (ask each time)",
and saving wrote that as a decision — the host would have been pinned to a
prompt nobody asked for and the group's key would never have reached it. Two
guards now: the picker is rebuilt when the group changes, and BuildHost writes
AsksForPassword only for a host that had the alternative on offer.

The group editor is here too, and the plan never assigned it a step. Without it
no group can carry a default, so every line above would have been unreachable.
It grows a parent picker that leaves out the group itself and everything
beneath it — a courtesy rather than the guarantee, since a cycle assembled from
two offline re-parents was never offered that list — and three defaults beside
the name, each of which may be left empty because "lend nothing" is an answer.

Tags are stored and not editable. TagIds merges, encodes and resolves; no
screen can set one yet, and the editor carries the set through a save untouched
so a client that can set them does not lose them to somebody editing a port.

Eight new tests, and they dial. That is the point of them: a resolved value
that never reaches SshConnectionRequest is a label, and every one of these
failures would be silent — a host connecting to the wrong port, or being asked
for a password it does not need, with nothing on screen admitting it.

Verified by the whole suite: 1390 tests over nineteen projects, none failing.
Both heads build. Nothing on the phone has changed.

ci / build and test (push) Successful in 1m12s

ci / api image (push) Successful in 24s
Taking pinch-zoom off the phone left nothing in its place, and there was nothing on the desktop
either. This is the replacement, and it is deliberately not the thing that was removed: zoom scales
what has already been drawn, so the remote goes on wrapping to a width that is no longer on screen.
Changing the font size refits the grid and reports the new column count, so the far end is told it
has fewer columns. That round trip is the feature.

The size is one number, owned by the shell. It has to be, for two reasons that pull the same way: it
must survive a relaunch, and it must be reachable from a phone that has no Ctrl key to press. So the
page asks and the host decides — a signed step over a new client opcode, answered with a size over a
new server opcode. The phone's buttons and the desktop's chords arrive at the same place, and a size
set by either is the size both remember.

Stored in settings.json beside the cache rather than in it, and that is not laziness about a
migration. The cache is encrypted and unreadable until a vault is unlocked, and the first terminal of
a locked launch needs the size already. Nothing secret may go in that file; ClientSettings says so
out loud, because the next person to add a preference is the one who needs to read it.

Where it is reachable from differs per head, and only here. The phone gets A− and A+ on the
connection line — not in the accessory row, which scrolls, and a control that fixes unreadable text
must never be the thing that is off-screen. The desktop gets the three chords every terminal
emulator has, answered by the page while a terminal has focus and by the window when it does not,
plus a row in preferences that shows the current value and names the chords rather than replacing
them. Someone whose terminal is too small to read is not in a position to go looking.

Clamped 8 to 32. Below eight a monospace grid stops being legible and becomes a texture, and every
column of it is still a column the remote is being told exists; above thirty-two a phone in portrait
has too few columns to hold a prompt. The buttons disable at the ends rather than accepting presses
that do nothing, which on a terminal reads as the application having stopped responding.

The preferences screen's header comment claimed none of the design's terminal settings could be
saved, and listed the three things that were missing to make one work. All three now exist, so it
says which one is real and why the other five still are not.

Verified with the protocol suite — including that the step byte round-trips signed, since read
unsigned a step down arrives as 255 and clamps to the largest font, making "smaller" do the most
dramatic available version of "larger" — a data-plane test that the chord is heard with no session
registered, and five shell tests: the default matches the renderer's, both clamps hold, reset works,
and a size chosen in one shell is there in a second one over the same profile directory. Layout
suite and both heads build.

jaap-janandClaude Opus 5 ddf0dd6a2b Stop the transfer tests depending on which thread ran them first
Every test in TransferQueueingTests failed on the Linux runner with "The calling thread
cannot access this object because a different thread owns it", and none of them had
anything to do with the commits in that run. The class drained its rows through
Dispatcher.UIThread.RunJobs(). That dispatcher is process-wide and belongs to whichever
thread touched it first, and xunit runs each test class as its own parallel collection — so
the moment a runner scheduled another class onto that thread ahead of this one, all nine
died inside DispatcherOperation.Execute having asserted nothing about transfers at all. It
passes locally and fails on a machine that schedules differently, which is the whole of why
this took a CI run to find.

TransfersViewModel now takes the poster it marshals through, defaulting to
Dispatcher.UIThread.Post — the seam VaultViewModel's clipboard already is, for the same
reason: a view model that reaches a process-wide UI object directly makes every test of it
depend on a thread it does not choose. No head passes the parameter, so nothing about the
running application changes.

The test supplies a queue of its own and drains it, which is the same shape the dispatcher
gave it. A poster that ran the action inline was tried first and is wrong: the transfer
queue raises Changed from its pump thread as well as from the call that enqueued, so inline
execution has a background thread adding rows to an ObservableCollection while the test
reads it — it passed once and then failed a different test on the next run. Draining keeps
every mutation on the thread doing the asserting, which is the one thing the dispatcher was
providing that was worth keeping.

One test added for the property that broke: queueing is reachable from any thread and must
not care which. The class as a whole guards the seam — remove it and nothing drains, so
every assertion about a row fails.

Verified by reproducing the failure first: a throwaway probe that touched the dispatcher on
one thread and posted and drained on another produced exactly the CI message. Then six
consecutive Release runs of the app suite, all green, plus the layout suite, which builds a
TransfersViewModel of its own.

jaap-janandClaude Opus 5 73c7e2a1e3 Point a release build at the hosted server, and a debug build at the clone
The shipped default was http://localhost:5233, which is the address the API serves under
dotnet run and a machine an installed application is not running. Somebody who installs a
release and accepts the field unread is signing in to nothing.

Two defaults now, because the two audiences never overlap. A release build offers
https://ssh.dodotech.cloud, so a first launch needs no address typed at all. A debug build
keeps the loopback address, and that half matters as much: shipping the hosted address into
a clone would point every development launch at production, and sign-in is the call that
provisions an account there.

The remark carries the reason the schemes differ, since the pair now looks like an
oversight rather than the deliberate thing it is — the API's first launch profile is
plaintext on 5233, and an HTTPS client meeting a plaintext port reports a TLS failure that
reads like a certificate problem.

The test spells out both branches rather than asserting the constant, which would pass
however it were edited. What it is really guarding is that a release never ships a
developer's loopback address and a debug build never points a clone at production, and it
can only guard those by naming them.

Verified by running the shell suite in Debug and in Release.

Connecting held the vault's busy gate, which meant a window that did nothing visible for
as long as a machine took to answer — and against one that is merely asleep, that is the
whole timeout. The gate is gone from that one command. A tab now appears in the strip in
the same turn as the click, carrying "connecting…" rather than a pane, and the terminal's
rectangle draws a card naming the host and the address being dialled. Every other screen
stays usable, and two connections can be in flight at once.

That splits the vault's one connection event into three, carrying an attempt id, because
"which tab is this about" can no longer be answered by "the most recent one". The id also
buys the two kinds of not-connecting their different endings: a refusal stays in the strip
as a tab holding its reason, since by then the user is quite likely three screens away and
a status line they are not looking at is not where a failure should end; a host key
question takes the tab away and puts the window back on HOSTS, because the prompt is drawn
there and a tab claiming failure would be competing with the thing about to resume it.

ConnectAsync takes no CancellationToken any more, and that is load-bearing rather than
tidying. A [RelayCommand] over a method that takes one generates a command that cancels
the previous execution's token on every invocation — so asking for a second machine
silently abandoned the first, measured as the first tab disappearing with "Cancelled." the
instant the second was asked for. Giving up on a connection is closing its tab, and a
session that lands after that is adopted rather than dropped: a shell running with nothing
naming it cannot be closed at all.

A tab is marked active on IsShowing rather than IsSelected. The selection survives
navigating away — that is what makes the strip a way back to a terminal instead of a way
to lose one — so a tab lit while preferences filled the window was a second "you are here"
mark pointing at something nobody could see. The nav rail's own entries have always made
this distinction.

The host list grows the two gestures it looked like it already had. A right click selects
the row under the pointer before opening a menu of Connect, Edit and Delete — the menu is
on the list rather than in the item template, so its entries are the vault's own commands
and not a row's, and it is cancelled outright over a group heading. Dragging a host onto a
heading files it there, onto a host files it beside that one, and onto UNGROUPED takes it
out of a group; the write is one field of one host through the same repository a save
uses, refused while the editor is open because a drop is a gesture on the list and not on
a half-typed form.

Clicking a result in the palette connects, which is what a list of hosts under a search
box looks like it does. It went through the shell's own command, so the pointer and Enter
take one path.

And the files screen's two pickers followed the vault's lists once, at unlock: a host or a
bucket created afterwards could not be picked until the keychain had been locked and
opened again, with nothing on screen explaining why the machine plainly in the host list
was missing. They follow the collections now, re-finding the selection by id across the
rebuild a sync pass causes every minute.

165 shell tests and 69 layout tests green, including the connecting tab, both failure
endings, two connections at once, a connection in flight across a lock, and the right
click acting on the row under the pointer rather than on the selection. The drag itself is
in docs/manual-checks.md with the rest of phase 7 — headless Avalonia has no platform
drag, and a test that claimed to have dropped something would pass while confirming
nothing.

jaap-jan 7a3a521c59 Give the phone the rest of its screens, and a way in
ci / build and test (push) Failing after 2s
ci / android head (push) Failing after 1s
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.

jaap-jan 2caedd93ff Merge branch 'main' into the Android head
Main grew the screens the host-management plan called for — hosts, pins, snippets, logs,
import, teams — plus the ObjectStore and Import projects behind two of them, and moved
WindowsDeviceKeyStore into the desktop head's Platform folder.

Five of those view models landed in a directory this branch had already moved, so they
join the rest in DodoSSH.Client.Shell: git spotted the rename and put them there, and the
namespaces followed. Shell picks up ObjectStore and Import as a result, which the Android
head then gets transitively and will use neither of at first — scoped storage means there
is no ~/.ssh/config to import, and file transfer is out of its first scope.

Desktop suites green at 155 and 64.

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.

jaap-jan 5cbda59a34 Merge branch 'main' into claude/host-management-ui-plan-7f20ab
Seven files needed a hand. Most were two branches adding something in the same
place, but three were one branch changing what the other had moved or renamed,
and those are the ones worth reading.

The shell keeps both new fields and both constructor lines: the connection
recorder this branch built and the teams view model main did. Where main put a
teams load inside OnScreenChanged, it now sits beside the logs refresh rather
than inside RaiseSurfaceState — this branch extracted that notification block
and it is called from two properties, so a screen-specific side effect in there
would fire on every terminal switch as well.

Main gave four row types a vault id and a vault name, and this branch had moved
one of them — KnownHostRowViewModel — into its own file when the pinned keys
became a screen. Git resolved that as "deleted here, modified there" and took
the delete, which compiles as long as nobody looks: the moved copy still had
the two-argument constructor and the call site had grown to four. Carried over
by hand, along with the ordering the pins list now does on them.

The status line's quiet rule was the subtle one. Main extracted it into
IsWorthReporting; this branch had changed the same condition to read item
counts rather than raw ones, because every user action queues a log entry a
moment later and this machine reads its own entries back on the next pull. Take
main's structure and the merge builds, passes, and silently restores a bug this
branch existed partly to fix — every save's message overwritten a second after
it appears. The method now reads PulledItems and PushedItems, with the reason
in its remarks.

Two conflicts were prose that had gone stale rather than code. The keychain
screen's comment said team vaults are refused by the server's access service,
which was true when it was written and is not now; main's replacement stands,
in this branch's vocabulary. The design-gaps row for groups was claimed by both
— real host groups here, per-vault headings there — and they are different
things, so both rows stay and the difference is stated: a group is a shelf the
user chose, a vault is who can read the item.

One defect the tests found and the compiler could not. Generating a key opens
the same editor as pasting one, but not through NewKey — so it never set the
target vault main added, and a generated key was filed into whatever vault was
edited last, or none. Both key-generation tests failed on it. Fixed where the
editor opens, with the reason recorded there.

One gap is left deliberately and is written down rather than half-built. Hosts,
keys, credentials and pins are read across every vault this session holds a key
for; groups are read from the active vault alone, so a host a teammate filed
shows under UNGROUPED. Nothing is lost or misfiled — it is what the sidebar
already shows for a group that has been deleted — but closing it needs a vault
id on every group row for rename and delete, and a way to tell two vaults'
identically-named groups apart under a layout with one heading per group. Both
are worth doing and neither is a merge's business. It is in the remarks on
ReloadGroupsAsync and in docs/design-import-gaps.md.

dotnet build, dotnet test and dotnet format --verify-no-changes are all clean:
1282 tests, including the end-to-end suite against real containers.

jaap-jan d07b336868 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.
