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-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 95816de0c5 Share a vault with a team, without the server holding a key
M3's teams, sharing and ACLs. Teams with roles, a public-key directory, the
append-only key log served for clients to check it against, team-owned vaults,
and vault key grants wrapped by a client and stored opaquely by the server.
VaultAccessService resolves team membership to PermissionFlags, so a viewer may
pull and may not push; the desktop client reads and syncs every vault it holds
a key for, and a real TEAMS screen replaces the one that said it did not exist.
No migration: team, team_membership, vault.team_id and vault_key_grant have all
been there since the first one, which is what carrying two unused tables bought.

Membership is authorisation. A grant is access. The obvious model is one
concept — "access", with a role attached, handed out by the server — and this
architecture cannot implement it: a vault key is sealed to each member's X25519
key, and only a client holding the plaintext can seal it for somebody else. So
"give Bob access" decomposes into a database write and a wrap, which happen on
different machines. Adding a member makes the server serve them the vault; it
cannot make it readable. VaultSummary.WrappedVaultKey is null in the meantime
and the vault appears in their list saying it is waiting for a key, because
hiding it until a grant existed would have been tidier and would have implied
the server was the thing granting access. The screen says the same thing after
every add, in the status line. ADR 0009 records the whole decision.

Sharing verifies or refuses. A directory lookup is a claim by the server about
a third party's public key, and wrapping to an unverified claim hands the vault
to whoever made it — no amount of transport security helps, because the server
is inside the threat model. KeyLogAudit reads the whole log, recomputes every
entry's hash from its own contents, checks the chain from genesis, and refuses
unless the offered key appears in it unchanged. There is no override flag: one
that exists gets used on the day the log is briefly unreachable, and the
resulting grant is indistinguishable from a correct one afterwards. What it
still cannot promise is that the key is the right person's, so the fingerprint
comes back for an out-of-band comparison and the success message says so every
time. A test corrupts the fake server's log by one byte and watches the client
refuse rather than warn.

The roles are only the ones that are enforceable. There is no ConnectOnly,
despite the design asking for one and TeamRole having room: SSH terminates on
the client, so a session needs the credential's plaintext on that machine, and
"may connect but may not read the key" cannot be enforced here. Shipping it as
an option in a dropdown would have been a lie. Connect rides along with Read
and is documented as an interface hint. Removal is named for what it does — it
revokes grants and flags the vault for rekey, and claims nothing about what is
already on somebody's laptop.

Three things are deliberately absent, and each is a refusal rather than an
omission. The rekey itself, because re-wrapping every item's data key under a
new vault key needs a client holding the current one; the server records that a
rotation is owed and the interface reports it, which is more honest than a
button that only appears to do it. Ownership transfer, because allowing an
owner to be removed without one leaves a team nobody can administer. And
cross-vault host key trust: a pin in a team vault is listed but not consulted
at connect time, because any member with Write could otherwise pre-approve a
fingerprint another member's client then trusts silently for a host in their
own vault. Scoping trust properly needs a scope on the SSH connect path, which
IKnownHostStore has not got; until then the narrow direction is the safe one
and the cost is in the README rather than hidden.

Reading now spans vaults and writing still does not. Every list on the vault
and hosts screens covers each vault the keyring opened, rows carry the vault
they came from, and an edit goes back to that vault rather than to the active
one — writing it to the active vault would fork the item and only show up when
a colleague wondered why their change never arrived. A new item goes wherever a
picker says, defaulting to the personal vault and never moving on its own,
because an item filed into a team's vault is visible to that team and moving it
back means deleting and retyping. The sidebar heading stops naming one vault
once there are two, and each row names its own.

The server checks what it can and nothing it cannot. It will not record a grant
for a key its recipient no longer holds, for a superseded generation, or for
somebody who is not in the team — each of those would otherwise surface days
later at the far end as a tag failure indistinguishable from corruption. It
does not verify the wrap or the signature, and the grant service says so: that
would be a convenience and never the boundary, and would put an asymmetric
implementation on a machine that is supposed to hold no keys.

Two bugs the tests found. TeamsViewModel's busy gate blocked its own reload, so
a team created a moment earlier was missing from the list it had just been
added to. And syncing every vault turned a failure from an exception into a
report, which made a background pass announce an unreachable vault once a
minute — the exact behaviour AnAutomaticPassThatFails_LeavesTheStatusAlone
exists to prevent. The fact is recorded and the message swallowed, as it was
before; pressing Sync still names the vault and the reason.

Also fixes a build break this branch started with: QuickConnectTests was never
updated when M2 added ISftpSessionFactory to the shell's constructor, so
nothing built at all.
