jaap-jan	3ead865f01	Merge branch 'main' into the desktop updater, and give way on two numbers ... Main landed a realtime push feature while this branch was building the updater, and the two collided in three places. Every one of them resolves the same way: main got there first, so this branch moves. **Two ADRs were both numbered 0012.** Main's is realtime push; this one is now [ADR 0013](docs/adr/0013-desktop-distribution-and-updates.md). Git did not call this a conflict — the filenames differ — so it would have merged quietly and left the directory with two 0012s and every cross-reference ambiguous. Renumbered here along with the nine places that point at it. **Two manual-check phases were both numbered 15**, and that one git did catch. Main's "Changes that arrive without a timer" keeps 15; installing and updating the desktop client becomes Phase 16, with its checks and every reference to them renumbered. The file's own rule is that a number is for life, which is exactly why the one that had not been pushed is the one that gives way. **The merge rewrote several files with CRLF**, and `.editorconfig` asks for LF on everything except `*.ps1`. That is not cosmetic here: IDE0055 is an error and `EnforceCodeStyleInBuild` is on, so it failed the build on three lines of App.axaml.cs whose only change in this branch was an ADR number in a comment. Forty-six files normalised back to LF; the release script keeps CRLF, which is what `.gitattributes` and `.editorconfig` both already say for a PowerShell file. Nothing else conflicted. The updater does not touch the sync loop or the event stream, and the one file both sides edited heavily — MainWindowViewModel — merged without a hunk in common. Verified after merging: the solution restores locked and builds clean, and 304 shell, 100 layout, 54 session, 28 client-api and 25 contracts tests pass. The first two counts are higher than before the merge because main's own tests came with it and pass alongside these.	2026-08-04 17:52:57 +02:00
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.	2026-08-04 17:11:06 +02:00
jaap-jan	6728a0a597	Let the desktop client replace itself, and give the repository one version ... Packaging for Windows, and the updater that only exists once something is packaged. Velopack, win-x64, fed from the project's own forge — never from the deployment a client signs in to, which is ADR 0011 rule 2 carried over unchanged and is why the feed address is a constant in the code rather than a setting. See docs/adr/0012-desktop-distribution-and-updates.md. **Nothing is ever installed while somebody is using it.** A newer build is found on a six-hourly pass, downloaded in the background, and then waits — for a restart the user presses, or for the next launch they were going to do anyway. That is a policy rather than caution: this application argues at length that locking keeps shells running, because a lock that destroyed work would stop being used, and a restart does not keep them. Having taught that, it owes the user the choice at the one moment it stops being true, and the sentence saying so counts the shells it would close. **The version is now derived from the v* tag**, by MinVer, for everything. There was no version before this — no property anywhere, so every assembly reported the SDK's 1.0.0 and the API served that string as its serverVersion to every client that asked. The tag was already the version of record for the container image; this makes it the version of record full stop. MinVer's failure mode is answering plausibly rather than failing, and here a wrong version is a client that never updates, so it is guarded twice: fetch-depth 0 on every checkout, and a step that fails a tag build when the tag and the computed version disagree. **The pack id is DodoSSH.Desktop and not DodoSSH**, which is the one decision here that would have destroyed data. Velopack installs to %LOCALAPPDATA%\<packId> and removes that whole directory on uninstall, and %LOCALAPPDATA%\DodoSSH is where ClientPaths keeps the encrypted cache, the outbox of changes not yet pushed, and the device key. The obvious id would have had the uninstaller silently delete work the server has never seen — the thing the application refuses to do without a counted confirmation. Velopack's own advice to move user data to roaming %APPDATA% is declined for the reason ClientPaths already gives. **Releases are cut by a person, and CI gains no job that could.** The tempting argument is that a forge write token is not a signing key. It does not survive contact with what the token does: Velopack clients trust their feed and do not verify a package signature when they apply one, so whoever can write a release can ship an update every install runs. That is the capability ADR 0011 rule 1 puts on a machine which is not a runner, reached through a different door. The mechanical objection — vpk needs Windows and the runners are Linux — is the smaller of the two and is recorded beside it, because somebody will fix one and believe they are done. Unsigned for now, deliberately and with the cost stated where a user reads it: SmartScreen warns once per person, on Setup.exe, because Mark-of-the-Web is applied by the browser that downloaded it. In-app updates are fetched by the application and applied from a local file, and never trip it. The banner is a fourth row of the window rather than an overlay. Anything drawn in the terminal's rectangle is sliced by the native child window that composites above it — the defect this window has shipped once — and a sibling row is the arrangement TitleBar and StatusBar already prove works. ---- Three defects surfaced on the way, none of them in the feature being built. **A settings key absent from the file came back as the CLR default, not the declared one.** The JSON source generator builds a record through a synthesised parameterised constructor and assigns every property from its argument array, so a property initializer runs and is then overwritten by a default for anything the file did not contain. A settings.json of {} read back a font size of 0, clamped up to the 8px floor rather than the 13px the renderer draws at. It could not bite while there was one setting, because that setting was written on every save and so was never absent; adding a second would have turned automatic update checks off for every existing profile, silently, the opposite of the documented default. Reflection-based deserialisation of the same JSON answers correctly, which is why every way of checking it by hand agrees except the one that ships. The defaults now live on the constructor parameters, which is the only place the generator reads them from. **Declaring a RuntimeIdentifier on the desktop head broke the server's image build.** It is the obvious way to let a self-contained publish restore under locked mode, and it writes a net10.0/win-x64 target into the lock file of every project the head references transitively — including DodoSSH.Contracts and DodoSSH.Crypto, which the API builds too. The Dockerfile restores those with no RID and fails NU1004. Found by running docker build rather than by reading. The RID stays out of the committed state; the two commands that need one ask for it unlocked, and the release script puts the lock files back. **A Docker ARG named VERSION silently sets MSBuild's Version.** An ARG is an environment variable for the rest of the stage, MSBuild reads environment variables as properties, and property names are case-insensitive. With the workflow passing main-<short sha> on a main build the publish died with NETSDK1018 pointing at DodoSSH.Contracts, a project nobody had touched. The build stage's argument is ASSEMBLY_VERSION now, empty except on a tag build. All three are in docs/platform-flags.md, which is where the next person will look. ---- Verified: the whole solution builds and restores locked; 289 shell, 93 layout and 54 session tests pass, including the regression test for the settings defect and a measurement of the banner at the window's minimum width. vpk pack runs end to end and reports "Verified VelopackApp.Run()" against Program.Main. The API image builds correctly both as a main build and as a tag build, carrying 1.0.0 and 0.1.0 respectively. Not verified, and it needs a published release to be: installing, updating and uninstalling on a real machine. That is Phase 15 of docs/manual-checks.md, and the pack id and the WebView2 profile fix are reasoned and commented but only proved by walking it. Two things to watch at the first upload — the reverse proxy's body-size limit for a 64 MB asset, and whether vpk upload gitea is happy with Gitea 1.27.1.	2026-08-04 17:04:41 +02:00
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.	2026-08-04 17:04:06 +02:00

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.	2026-08-04 16:37:41 +02:00
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.	2026-08-04 16:04:15 +02:00
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.	2026-08-04 15:34:40 +02:00
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.	2026-08-04 13:58:56 +02:00
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.	2026-08-04 12:22:29 +02:00
jaap-jan	805d81dbcc	Merge branch 'claude/team-key-share-rotate-4b2619' ... 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.	2026-08-04 10:23:46 +02:00
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.	2026-08-04 10:18:14 +02:00
jaap-jan	cba6f435e9	Merge branch 'claude/vault-creation-sharing-62c0b6' ... # Conflicts: # README.md	2026-08-04 10:10:40 +02:00
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.	2026-08-04 10:07:16 +02:00
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.	2026-08-03 23:05:40 +02:00
jaap-jan	fd8497bb76	Merge branch 'claude/sftp-s3-connection-ui-b0730f'	2026-08-03 15:51:19 +02:00
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.	2026-08-03 15:50:31 +02:00
jaap-jan	562fb444a8	Merge main into the phone connections branch ... 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`.	2026-08-03 15:26:47 +02:00
jaap-jan	1b7df47537	Merge main into the desktop redesign branch ... Four conflicts. Three were two people adding to the same spot, and one was a real collision: main gave the connect bar a REMEMBER tick in the same pass that this branch took the connect bar off the hosts screen. REMEMBER is now in the drawer, beside the password box it qualifies. Nothing about the feature changed — RemembersConnectPassword, its refusal to fire until the remote has accepted the password, and the six tests over it are main's untouched — only where it is drawn. The move improves it slightly and it is worth saying why rather than claiming a merge was neutral: the bar had one row and had to fit the box, the tick, the authentication note and CONNECT along it, which is why the tick was a bare "REMEMBER" in tracked capitals. A column has room to put it under the box as a sentence, where it reads as a property of the password rather than as a fourth control in a row. MainWindowViewModel: both sides added members after ShowTerminal — the desktop's three fixed tabs here, the phone's connect menu on main. They do not interact, so both are kept, each under its own heading. TeamsScreen: main added the team's own RENAME, HAND OVER and ARCHIVE, a member's LastActive, the role a new member arrives as, and the KEY HOLDERS list. This branch had only bumped the file's font sizes a point. Resolved by taking main's file whole and re-running the bump over it, so the new controls join the scale rather than sitting a point below everything around them. README: both sides described a different head's third pass in the same paragraph. Both kept. Two things checked rather than assumed, because this branch moved the furniture the merged commits sit on. The chrome heights main's terminal work touched are the phone's, not the desktop's — 44, 42 and 24 are unchanged, so the layout harness's budget still describes the window. And main's keychain DELETE did not reach VaultScreen.axaml, whose header this branch rearranged, so the five buttons that overflowed at the larger type are still five. 2415 tests pass, up from 2369 by the 46 main brought.	2026-08-03 15:17:55 +02:00
jaap-jan	208443b932	Move SFTP and S3 into the tab strip, and the host list into a card grid ... Four asks in one pass over the desktop head, and two of them are furniture moving rather than anything new. THE STRIP IS THE WINDOW'S NOW, not the terminal's. Vaults, SFTP and S3 sit at its head and cannot be closed, and open terminals follow them. SFTP and S3 left the nav rail to get there, which is the one semantic change: they are the two destinations you stay in while something runs, and a rail entry is for somewhere you go and come back from. So the rail belongs to the Vaults tab and collapses with it, which also means SFTP, S3 and a terminal each get the full 1016 rather than the 826 a page gets. The tab is expressed as "a page, and not one of the two the strip took" rather than as a fourth ShellSurface. Both are still ShellScreen members and have to be — that is what they are on the phone, where they are two rows in a hub — so a surface each would have been a second way to say a thing Screen already says. IsTransfersShowing and IsBucketsShowing light the other two tabs unchanged. What is new is one field: the page Vaults comes back to, because it is the one tab with sub-navigation and therefore the one that can return to the wrong place. That is not the hidden field ShellSurface argues against — that one would be a second copy of "which page"; this is a tab remembering its own. THE HOSTS SCREEN IS A GRID, and the 268-pixel sidebar is gone. That column was choosing among forty machines and editing one of them at two-thirds width, and it was narrow so the editor beneath it could be a column at all. Cards took the first job at full width; a 304-pixel drawer took the second and collapses when nothing is selected. Pressing a group card narrows the grid; SHOW ALL is the way back. The group editor moved into the drawer as well, which finally makes IsEditingGroup mean the same thing on both heads — it was the phone's alone, because the desktop's editor was a bar that was always on screen. AreHostsExpanded and ToggleHosts went with the control that used them. They folded the whole list away under one heading, an affordance that existed because the column was narrow. Folding a single group is a different thing and is still here. THE TYPE SCALE IS A POINT LARGER and the text ramp is white. The base size was never stated anywhere — a bare TextBlock took TextElement's default of 12 — so raising the scale meant naming it, on Window and on UserControl. The second selector is not redundancy: the layout harness hosts a UserControl in a window it builds itself, and without it the suite would measure every screen a point smaller than it ships, silently. A selector on TextBlock would have been the obvious way and is wrong, because a style setter beats an inherited value and would collapse every deliberate step back to one number. #E3E7F4 is a blue-tinted white on blue-black surfaces, which costs contrast twice — once for being darker than white and once for sharing a hue with what it is drawn on. Pure white is 18.3:1 against the canvas where that was 15.5:1. Every step below moved with the top, so the intervals the design chose are kept and TextDim clears 9:1 against 6.4:1. The palette is shared, so the phone has both changes too. TWO DEFECTS THE HARNESS STRUCTURALLY CANNOT SEE, found by rendering the screen rather than by measuring it, and both now covered. The tile was 232 and was first written as 248, from arithmetic that left out the scrolling stack's own margins. Every layout test passed — the harness asks whether a control is inside the window, never how many fit on a line — so the grid quietly became one column wide at exactly the minimum this application guarantees, which is the shape cards exist to avoid. TheHostsGridKeepsTwoColumnsAtTheMinimumWithTheDrawerOpen counts columns instead, and fails at 248. And a card's text ran past its own border, because a horizontal StackPanel measures children with infinite width: a TextBlock inside one never learns it is short of room, so TextTrimming never fires. Both card rows are grids with a star column that gives way and an Auto column that does not — a hostname with its tail cut is still the machine you were looking for, where a badge or the word naming an auth method is not. The keychain header changed shape for the same class of reason. It was Auto,Auto,*,Auto with the buttons last, so the slack column was the only thing absorbing a change of width and five buttons fell off the right edge the moment the type grew. That is how GENERATE lost the word KEY once already. The summary sits in the star column and trims now, so the buttons always get their width. HostSidebarTests became HostGridTests and moved to the grid with the gestures it drives. docs/design-import-gaps.md gains a v3 section naming the five toolbar controls in the design with nothing behind them — a view-mode switch, a tag filter, a calendar, a share control and Serial — and manual-checks.md and the README follow the controls that moved.	2026-08-03 15:08:48 +02:00

jaap-jan	5800a4bbd0	Give the keychain the DELETE its confirmation was already written for ... The counted confirmation has been on this screen since the phone got its screens, and nothing could raise it. PendingDeletion is armed by DeleteSelectedItemCommand and its siblings, and the only Delete bindings anywhere on this head were the files screen's remote delete and the snippets one — so the card, and the header comment calling it structural, described a question the phone could not ask. The button is what was missing rather than anything behind it: the command, the counting and the wording were all already shared with the desktop. It sits in row 2 beside that confirmation rather than in a bar at the foot of the screen, which is where HOSTS and FILES put what to do with the chosen thing. ShowsItemActions is SelectedItemIsEditable and not-already-asking, so sharing the row makes the question take the place of the button that asked it, and DELETE cannot be pressed a second time underneath its own confirmation. A button at the bottom and its question at the top would be one exchange drawn twice. DELETE alone, without the EDIT the desktop's detail pane offers beside it, because there is nothing on this head for EDIT to open. That is also why the bar names the item rather than trusting the highlight: it is the only thing on screen saying which row is about to go. And the highlight had to be made to exist. HOSTS and FILES fill the selected ContentPresenter, which works because their rows are bare Borders; a keychain row is Border.card, and the card paints an opaque Sidebar over it. The selector reaches the card itself instead, in the same Active the chosen host wears, so the row a button now acts on looks different from the ones it does not. The TAGS comment said renaming and deleting happened here. Half of that is true as of this commit and the other half is not — a tag is still renamed on the desktop, because no kind of item opens an editor on this screen. The README's paragraph about what the phone is missing said there was no host editor, which stopped being true when the floating + and both editors landed. It now names what is actually absent: no local pane for file transfer, no keychain editor, and no screen at all for pins, teams or import.	2026-08-03 14:54:19 +02:00
jaap-jan	a2f0d4813a	Take a third off both of the terminal's bars, and centre the cross in a tab ... The bar the last commit put above a shell opened at 52 and the accessory row under it at 50, both inherited from the arrangement they replaced rather than measured against the one they are in. Neither is carrying a title or a sentence any more — the top one holds two icons and a row of pills, the bottom one a line of keys — so a third comes off each: 35 and 33. Every height inside them came down too. The pills go 44 to 30, the icon squares 34 rather than 44, the keys 38 to 30. A bar that shrank around contents that did not would not have saved anything; it would have moved the clipping somewhere harder to see. Two of those numbers had arguments written against them and both arguments change rather than disappear. The pill was 44 because it contains the one control on this head that is destructive with neither confirmation nor undo, and that is now carried by width — the cross keeps its full 44-pixel column, and what it gave up is vertical slack in a row where nothing sits above or below it to be hit by mistake. The keys were 38 for the same kind of reason, and the 44 that mattered there was always the width: ten keys flexed across 360dp is 32 pixels each, which is what the horizontal minimum exists to refuse. Both comments say what replaced the reasoning rather than quietly showing a smaller number. The close cross was not vertically centred, and it was not a rounding error. `Button.row` sets `HorizontalContentAlignment` and says nothing about the other axis, so the glyph sat against the top of its own column while the label beside it was centred by the stack panel it lives in. On the control that ends a session that reads as a misprint. Both alignments are now stated, on the button and on the text. The `+` loses the accent and becomes the same `Button.icon` as the arrow across from it. The two are a matched pair at either end of one bar — one leaves this surface, one adds to it — and an accented one ranked itself above the way out. The accent fill belongs to the floating `+` on HOSTS, which is the only action on its screen; this one is not. Five pixels between the renderer and the keys, as a margin rather than a border. The renderer is a native child view and nothing Avalonia draws can sit on top of it, so a hairline there would have to be a row of its own — and a terminal whose last line of output is flush against a row of grey keys reads as one surface that has gone wrong rather than as two that are different things. The four places that named the old bar height are corrected, including manual check 11.5, which asserted a number that would now fail.	2026-08-03 14:54:16 +02:00
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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-03 14:40:27 +02:00
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.	2026-08-03 14:33:16 +02:00
jaap-janandClaude Opus 5	a43286ece8	Let a team change hands, and be joined by somebody with no account yet ... M3 built teams and stopped short of the two operations that decide who controls one. Both were written down as refusals rather than omissions: ADR 0009 listed ownership transfer under "deliberately not built", and design-import-gaps said an invitation needed "a token with a lifetime and an outbound mail path". One of those reasons had expired and the other never applied — an invitation does not need a token if it is not a thing anybody presents. Handing a team over is one write. The member you name becomes owner and you become an admin, in a single transaction, because ownership is sole: promoting first leaves the team owned twice, demoting first leaves it owned by nobody, and there is nobody left with the authority to finish a transfer that stopped in the middle. That is also why it is not two calls to the role endpoint, which refuses Owner outright. The outgoing owner is demoted rather than removed — removing them would revoke their vault key grants and flag every team vault for rekey, which is a far larger act than the one asked for, and somebody handing over a team is usually staying in it. It unblocks the thing that was impossible before: an owner can now leave, by handing the team on first. An invitation is a standing instruction rather than a message. This server has no outbound mail path, so nothing is sent and there is nothing for the invitee to present. The row says the next account signing in with that address joins this team at this role, and telling them to sign in is the caller's job over a channel this server does not carry. A link nobody can deliver would be worse than none. It lives in its own table rather than becoming a membership with MembershipStatus.Invited, and that member stays unwritten for the reason it always was: team_membership.user_id is not nullable and carries a foreign key, so somebody who has never signed in has nothing for that row to point at. Widening it would make the unique index on (team, user) meaningless, because PostgreSQL counts every NULL as distinct. Verification is the security boundary, and nothing in this server read it before. A claim requires the access token to assert email_verified. An invitation decides what the server will serve, so one claimable by anybody able to obtain a token carrying somebody else's address is a way into a team — which is precisely the attack OidcOptions.AllowEmailLinking exists to refuse, and it would have been reintroduced by the back door. There is deliberately no setting that relaxes it: a flag that exists is one somebody turns on for the afternoon their provider is misconfigured. Absence is refused rather than trusted, and logged, because a provider that never sends the claim otherwise leaves every invitation pending with nothing anywhere saying why. Claiming happens at just-in-time provisioning and again on an hourly sweep. The sweep is what makes it recoverable rather than one-shot — an invitation issued between an account being created and that person next signing in would otherwise be stranded for ever — and it shares its rate with the last-seen write because both are housekeeping nobody is waiting on. Archiving is refused while a team owns a vault, and that refusal is the end of the road rather than a step on it. A team vault is readable because of membership, so archiving one that still owned vaults would take them away from everybody holding a key, including the caller, quietly and all at once. Nothing in this product deletes a vault, so no order of operations gets past it today — which is stated with a count of what is in the way, for the reason the SFTP layer refuses a recursive delete: a refusal is visible and a quiet removal is not. It is owner-only, as handing over is; renaming is not, because a rename is visible to everybody and reversible by anybody who can do it. The slug is not renameable at all: it is unique only among live teams, so a rename could take one an archived team is still holding, and that team could then never be restored. LAST ACTIVE is real and coarse on purpose. UserAccount.LastSeenAtUtc is refreshed on ordinary authenticated requests, at most once per account per hour, through ExecuteUpdateAsync — user_account carries the xmin concurrency token, so a read-then-write on the hot path would start losing races between one user's own overlapping requests. An hour is the granularity the question is actually asked at, and the interface draws it to the day rather than the minute so it does not read as a precision that is not there. The remarks in Contracts and in the view model that argued at length for the column's absence are rewritten rather than extended; both had become false. Two endpoints already existed and nothing called them. ChangeTeamMemberRole and ListVaultGrants have been reachable since M3. The role picker refuses Owner itself rather than letting the server do it, since the interface already knew the rule; the key-holder list sits under the vault rather than beside the member, because a grant is per vault and a count on a member row would imply per-item sharing, which is M5. It lists withdrawn and stale grants and says which they are — a list that dropped them would show a departed colleague as merely absent rather than as somebody whose key was taken away — and staleness is decided by comparing generations, since a grant can be Active and still open nothing. ADD MEMBER stopped being a dead end. An address the directory did not know used to end at a sentence telling the user their colleague had to sign in first. It invites them instead, from the same button, because which of the two applies is a fact about the server's account table rather than about what the user is doing; which one happened is reported afterwards, because that decides what they do next. An address that merely has an account is invited rather than refused: refusing would have made the endpoint an oracle for which addresses have accounts here, answerable by anybody willing to create a team first. The phone has a TEAMS screen, behind MORE, and it is the reverse of every other row in design-import-gaps: a shipped screen the design had no slot for. It is there because an invitation is claimed by signing in, so somebody told they are now in a team is at least as likely to be holding a phone — and a membership visible only on a head they never installed is one they cannot see. It draws SHARE KEY and nothing that takes something away: wrapping a key is the one act on that screen a server cannot perform at all, and the desktop guards its revocations with a tooltip, which is a control a touch screen cannot show. Two defects were found by an adversarial pass and both were green against the whole suite at the time. The owner-only check on archiving and handing over had been weakened to the admin check while their messages and comments still said owner — and since nothing behind the archive endpoint re-checks it, an admin the owner had promoted could have archived the team out from under them. And the rename endpoint built its response with a hardcoded Owner role, so an admin who renamed a team was handed a summary claiming they owned it, and a client trusting that instead of re-listing would have offered them the two owner-only buttons the server then refuses. The new table gets its constraints tested rather than merely migrated: live uniqueness per (team, address), the citext proof that an address typed by a person matches one cased by a provider, and reissue after both revocation and acceptance. The teams screen gets its first entries in the layout suite, at the minimum window with every list populated and with each of the two states that cover half of it — it had none, and it just grew four sections and a second line in the member row.

jaap-janandClaude Opus 5	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	3627021420	Give the desktop the second design too, and the window the size it now needs ... The desktop v2 design is the other half of the one the phone took last commit, and this is its chrome: a 190-pixel labelled sidebar where the 54-pixel icon rail was, a titlebar with the search box centred in it, and session tabs drawn as pills. The palette was already here — it is shared, and moved when the phone's did — so what this changes is shape rather than colour. **The window's minimum grew, and by exactly what v2 added.** The sidebar is 136 wider and the chrome 14 taller, so 880x560 became 1016x574. That is not a round number somebody liked: it leaves every screen the same 826x464 it was designed against, which is the arithmetic the layout suite is built on. Four of the tables stop fitting at 690 wide, so widening the sidebar and leaving the window alone would have broken them somewhere no test was looking. LayoutHarness carries the new constants and the suite still passes at the minimum, which is the whole reason it exists. The rail's five-character abbreviations are gone with the width that caused them — PINS and SNIPS are Pins and Snippets again — and each row gains a glyph and a count. A count is drawn only where one is real, so SFTP, Logs and Preferences show nothing rather than a zero: a transfer queue's depth is not how many files a screen holds, and a log has no total until it is read. The count beside Pins is the vault's own, not the Pins screen's VisiblePins, which is the filtered list and would have made the sidebar count whatever somebody had just typed into a filter box on another screen. Teams has no count for a related reason: they are read from the server when that screen is opened rather than on unlock, so a number there would read 0 until somebody had already been to look. One colour moved with it, finishing what the repalette started: the live-session summaries on the unlock and sign-out cards were Info, so the two heads disagreed about a fact the phone paints green. They match again. **Buckets became a destination rather than a mode**, which is what the design draws and what the phone already does. The HOST / BUCKET pair inside the files screen is gone; ShellScreen.Buckets draws the same TransfersScreen with the other picker, and the sidebar entry is what sets it. That also settles an old disagreement rather than merely moving it: TotalItemCount is keys plus passwords and excludes buckets, so the number beside the keychain used to disagree with the list under it, and now counts what that screen shows. There is one session behind both file destinations, so asking for the other kind while something is open is refused rather than obeyed — and refusing means staying put. An earlier turn of this had it move anyway and only decline to switch the picker, which put the S3 entry in the sidebar over a screen still listing an SFTP host: two pieces of chrome disagreeing about where you are, which is worse than the navigation simply not happening. The message that says so goes to Transfers.Status, which turned out to be drawn in the same grid cell as the connected chip — survivable while it was mostly read before connecting, and not once a refusal reports itself there. It has its own column now. The design has nine entries' worth of screens and draws five. Pins, Teams, Import and Preferences are built, working screens, so they keep their entries — the sidebar is labelled now and has the room, and dropping an entry would have stranded a screen rather than simplified anything. The Team vault card the design pins to the foot is not drawn: it is a second route to a screen already in the list, carrying a seat count nothing here produces. **The status bar survives the design that deletes it**, cut down to one thing. Two of the three facts it carried moved into the titlebar with v2 — the sync word is beside its dot and the shortcut hint is inside the box that uses it — so those are gone from it rather than printed twice. The third is Vault.Status, the only channel this application has for saying a save failed or a merge picked a winner. The design is a mock-up of an afternoon that goes well and has nowhere to put a sentence like that; dropping the bar would have meant dropping the sentence or repeating it on nine screens. What v2 draws and this does not is in docs/design-import-gaps.md, and it is the same list as the phone's for the same reasons: the forwarding screen and both its chips, the host detail's fingerprint, tags and last-session cards, the keychain's rotate button, the logs' FOLLOW pill and severity filters, and the session footer's latency. The terminal is not inset behind a rounded frame either — it is a native child window that composites above everything Avalonia paints, so the frame would clip nothing, which is the same answer the phone gave. **The light theme is not built.** Its accent is #6D5AE6, a different hue rather than a tint of the dark one, so it needs every colour doubled, a variant to switch on, the renderer's own page switching with it, and contrast checked twice. That is a piece of work rather than a setting, and it is separable from the layout — which is why this commit is the layout. The screens themselves are restyled through the shared vocabulary rather than rebuilt: corner radii, chips, cards and the accent's ink, all in App.axaml, so every screen moves at once. Their layouts are left alone deliberately. The design draws read-only detail panes and these screens carry the editors and forms it has no equivalent of, so replacing a layout with the mock-up's would have lost the half that is actually used. Verified by the whole suite: 1309 tests over nineteen projects, none failing, including the 68 layout cases that stand up real Avalonia and measure every screen at the new minimum. Both heads build. Not run on a machine with a display — see docs/manual-checks.md for what wants looking at.

jaap-janandClaude Opus 5	5593f337b6	Give the phone the second design, and both heads the palette it arrives with ... The Android v2 design is what this head draws now: four destinations in a bottom bar — Hosts, Terminal, Keychain, More — with snippets, SFTP, S3, logs and preferences one tap deeper behind the last. The first design's four had nothing behind them, which is what made a hub worth building. The palette moved from green-black to blue-black, and it moved in the shared project because that is where it lives and the desktop v2 specifies the same seventeen tokens. One colour changed meaning rather than value, and it is the only semantic change in the file. Green used to *be* the accent, so Ellipse.dot.live filled with Accent and "the thing to press" and "a shell is open on this host" were the same colour by construction. v2 makes the accent blue and keeps a green for status alone, which finally separates them: Live is that green and nothing merely interactive may use it. The accent is also two colours now — Accent fills, AccentText writes — because a row of chips in the fill colour is a row of things that all look like the primary action. A palette is not one file, which is the part worth knowing before the next one. Nine hex literals lived outside it: the nav bar's own label colours, the accessory keys and their Ctrl-latched state, two scrims, the window background Android paints before Avalonia has a frame, and the launcher vector. The two C# sites now resolve from the dictionary by name rather than restating it. The renderer's page cannot — it is served to a WebView over a loopback socket — so terminal.css and terminal.js keep hand-copied values and say so at both sites. ShellScreen gained More and Buckets, appended rather than slotted in. SFTP and S3 are one screen over one TransfersViewModel differing only in which picker they offer, and the kind is set by the button that navigates rather than on arrival — doing it in OnScreenChanged made every arrival at Transfers force the picker back to hosts, including the desktop's own rail arriving at a screen with a bucket already open. It refuses to change kind while a session is live, because there is one session behind both destinations and switching under it would title a screen S3 while it listed an SFTP host. What the design draws and this does not, on the usual grounds. The FORWARDING screen: nothing here forwards anything, so every toggle would be a control with no effect — it is a paragraph on the hub naming the absence, for the reason the desktop keeps TEAMS in its rail. The terminal's `23 ms · fwd 5432`. An ED25519 badge and a SHA256 line on keychain cards, which need an algorithm field and a fingerprint the item type does not have. An `agent` chip, for an agent that does not exist. Snippet run history and exit codes. The Logs FOLLOW pill, which claims a live tail over records that are written once at close and read when the screen opens, and the severity filter, which has nothing to count — that chip row is spent on the real choice, which of the two logs. S3 bucket totals and lifecycle. And the + on HOSTS, which would open a host editor this head has not got. SFTP is browse, open and delete. Both transfer commands work, and what they work against is the local pane: QueueDownloads writes to Path.Combine(LocalPath, name), and LocalPath starts at SpecialFolder.UserProfile, which on Android is the application's own private directory. A download would have reported success and left the file where the person who asked for it cannot open it, which is worse than not offering it — a refusal is visible and a file in /data/user/0/ is not. The queue is not drawn either, since nothing here can put anything in it. Both return with the document picker. The foreground service still counts zero transfers, and the reason moved rather than went away. Four defects worth naming, because three of them are the kind that compile. A Button as a ListBox ItemTemplate swallows the pointer press before the list sees it, so the files listing selected nothing and every command reading the selection did nothing — the row is a Border now and the phone-only single-tap-to-open is a Tapped handler, which also keeps a desktop single click from walking into directories. Avalonia type selectors are exact, so TextBlock.fingerprint never matched SelectableTextBlock and every fingerprint on this head rendered proportional and unwrapped: that was breaking the never-truncated rule on the host-key sheet already. The new two-level hierarchy had no handler for the system back gesture, so back left the application from a log screen. And the tab's close cross had shrunk to a 30x32 target flush against the select target, which is the one control here that ends a shell with no confirmation and no undo. Fingerprint unlock is raised on arriving at the lock screen rather than waiting for its button, which is still there. Only at launch: a lock the user asked for is not answered with an immediate request to unlock, which makes LOCK look inert and trains the reflex of authenticating at a prompt nobody asked for. And once, because a declined gesture leaves the passphrase box exactly where it was and a prompt that came back after being dismissed would be a modal you cannot get out of to type into it. Two fixes fall on the desktop. Its file listing coloured directories with Info and executables with Accent, which was blue against green and is now two steps of one blue; an executable is Live now. And a bucket's folders were drawn with a 0001-01-01 timestamp, because a prefix has no modification time — blank now, for the reason a directory's size is blank. Verified by the whole suite: 1309 tests over nineteen projects, none failing, including the layout suite that stands up real Avalonia and parses every desktop screen. Both heads build. Not verified on a device — nothing in this head ever has been; see docs/android-port.md.

jaap-janandClaude Opus 5	ffab2be22a	Drop the formatting step, which spent minutes agreeing with the build ... `dotnet format --verify-no-changes` re-analysed the whole solution before the build did, to reach a verdict the build reaches on its own: IDE0055 is an error in .editorconfig, EnforceCodeStyleInBuild is on and warnings are errors, so a misformatted file fails the build step. What the separate step bought was hearing about it a few minutes earlier, and it charged those minutes on every run. Checked rather than assumed, because the whole justification rests on it: appending a badly-spaced member to a source file produces three `error IDE0055` lines and a failed build with no format step in sight. Three places said the old arrangement out loud and would now be wrong on their own — the comment on the IDE0055 line, the conventions list in the README, and a note in platform-flags telling people to run dotnet format before pushing or CI would fail them. They say the build enforces it now. dotnet format is still how to fix what the build complains about; it just no longer gates anything.

jaap-janandClaude Opus 5	093f3904c1	Apply pending migrations at startup instead of asking for a second command ... The API deliberately never migrated: it failed readiness while a migration was pending and named it, and a separate step applied them. That is the right split for a deployment with a release pipeline and the wrong one for a self-hosted server, where it means an image that boots, refuses traffic, and waits for somebody to know that dotnet ef exists. The schema and the code that expects it ship in the same image, so the image is where the two are reconciled now. Before RunAsync rather than in the background. A migration racing the first requests would let them through against a half-applied schema, and the first authenticated request is the one that provisions accounts. Failing to migrate therefore fails to start, which is the loudest signal available and the one an orchestrator already acts on. Concurrent starts take a Postgres advisory lock first. Without it two replicas rolled out together read the same empty history table, both apply the same migration, and the second dies on an object that already exists — a crash loop on the day of a schema change, which is the worst day to have one. The lock is held on a connection of its own because EF opens and closes one per command, and a session lock belongs to the connection that took it. The exception is a database that does not exist yet: there is nothing to hold a lock in, so that path migrates without one and says so. Two instances creating it at once still converges — one wins, the other restarts into the ordinary locked path — and refusing to start would leave a fresh deployment stuck on the step this removes. Database:AutoMigrate turns it off for the deployments that own their schema: a migrator job, a rollout where new code must run against the old schema first, or a database user denied DDL. With it off the behaviour is exactly what it was, and the health check now explains which of the two situations a pending migration means. Verified against a throwaway PostgreSQL container: an empty database gets all seven migrations applied before the port opens, the tables land in the dodo schema, and a second start logs the schema up to date and serves. The API suite passes, which exercises the startup path once per assembly. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-01 21:12:22 +02:00
jaap-janandClaude Opus 5	43d76d0f2d	Let the suite run on Linux, and fix the three things that stopped it ... The pipeline finally reached the tests and found four failures. None was the pipeline's, and only one of the four was a test being fussy about a platform rather than telling the truth about one. The local pane's roots bar was the real bug. LocalDirectory.Roots built it from DriveInfo.GetDrives on every platform, and its own summary — "the drives on Windows, and the root elsewhere" — had been describing an intention rather than the code for as long as nobody ran it off Windows. On Unix that call answers with every mount the kernel holds: /proc, /sys/fs/bpf, one per installed snap, /run/user/1000/doc, some forty on an ordinary laptop. The transfers screen draws a button per root, so the bar ran to about five thousand pixels inside an eight-hundred pixel window. Anybody running the Linux build has been looking at that. Filtering GetDrives is not the fix and the comment now says why at length, because it is the obvious thing to try: DriveType answers Fixed for / and /home and equally for every squashfs snap, for efivarfs and for tracefs, while /boot/efi comes back Removable, and DriveFormat would need a hand-kept list of every virtual filesystem Linux might grow. So Unix now names what somebody would want instead of subtracting what they would not — the root, their home, and whatever is mounted under /run/media/<user>, /media, /mnt or /Volumes. Anything else is still reachable by navigating from /, which is what the pane is for. Windows is untouched. ClientPathsTests looked for "odoSSH" in the profile directory. ClientPaths spells it DodoSSH on Windows and dodossh on Unix deliberately, one per platform convention, and that substring was clever enough to survive either spelling of the leading D while still only ever matching one of them. Now OrdinalIgnoreCase. WhyTheWindowItselfIsNeverShown asserted a COMException with HResult RPC_E_CHANGED_MODE, which is WebView2 refusing an MTA thread — a Win32 component raising a COM error. On Linux the adapter is a different implementation with no apartment to disagree about, so showing the window works and Should.Throw catches nothing. Skipped there rather than loosened to accept both outcomes: the assertion is the documentation in that test, and one that passed everywhere would have stopped recording the constraint it exists to record. The fourth was CI's alone, and the diagnosis is the useful part. All 69 layout tests failed on the runner while 6 failed here, which looked like missing fonts and was not: Avalonia's headless renderer is Skia, libSkiaSharp.so links against libfontconfig, and without it the suite dies in HeadlessUnitTestSession with a TypeInitializationException on SKImageInfo naming none of its actual subjects. The job installs the one library now. Verified in a container where fc-list returns zero and the suite passes regardless, because the application carries Inter itself — fonts were never the problem, only the thing that would have looked for them. The whole solution now passes on Linux: 19 suites, 1295 tests, 0 failures, 4 skipped, the end-to-end Testcontainers suite included. README and platform-flags.md said testing was Windows-only, which CI now contradicts on every push, so both say what is true instead and the two findings are written down where the next person will look for them. macOS is still untested and now says so on its own rather than hiding inside "not Windows".

jaap-jan	7a3a521c59	Give the phone the rest of its screens, and a way in ... 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.	2026-07-31 21:43:11 +02:00
jaap-jan	81e7e6d939	Write down what the phone found, and stop it rotting ... docs/android-port.md was an audit of work not started; it now says what is built. Three of its statements needed correcting rather than extending, and they are marked where they sit: the Android version question is settled and was never as open as it looked, because Avalonia.Controls.WebView ships only a net10.0-android36.0 assembly and nothing lower can resolve it; cleartext to loopback has to be permitted explicitly, which the audit missed entirely; and the spike produced a structural change it did not anticipate, in DodoSSH.Client.Shell. A CI job of its own, because the head is deliberately not in DodoSSH.slnx and a project outside the solution is a project nobody notices breaking. It packages as well as builds: a native library with no Android ABI and an assembly that will not dex are both invisible to a compile, and both are exactly what this head is exposed to. The README says plainly that signing in is not built, that a fingerprint re-enrolment destroys the device key, that a notification appears while a shell is open, and that none of it has run on a device.	2026-07-31 21:09:42 +02:00
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.	2026-07-31 20:44:39 +02:00
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.	2026-07-31 20:30:05 +02:00
jaap-jan	23eca3a21b	Merge branch 'main' into claude/m3-implementation-57f9d7 ... Three files conflicted, and two of the resolutions are more than a choice of side. QuickConnectTests had both branches fixing the same build break — main's M2 merge left the shell's constructor with an ISftpSessionFactory nobody passed. Main's version wins because it carries a comment saying why the palette never needs a session. VaultSession's conflict is adjacent edits: main added the remembered sign-in members and this branch changed SyncAsync's summary from "the active vault" to "one vault". Both kept. VaultViewModel is the one that matters. Main taught the background pass to report a sync that had to start over, on the grounds that a machine which silently re-read a whole vault has had something happen to it; this branch turned a pass into one report per readable vault. Taking either side alone would have lost the other, so ResyncedFromStart is now one of the conditions IsWorthReporting checks, per vault. Merging also broke something neither branch could have caught alone, and the build would not have said a word. SyncOnceAsync cleared LastSyncFailed unconditionally, which was right while a pass was one vault and a failure was an exception that never reached that line. A failure is now a report — one unreachable team vault must not stop the others syncing — so the flag was being cleared over a vault that had just failed, lighting the titlebar SYNCED. It is computed from the report instead, in the one place both callers go through, so the manual command gets it as well as the loop. The background pass still swallows the message and keeps the fact, which is what AnAutomaticPassThatFails_LeavesTheStatusAlone is there to hold it to. Two comments the auto-merge left describing a world with one vault in it: the SCOPES rail's, which said team vaults are refused by the access service, and the host sidebar's "One heading, for one vault".	2026-07-31 12:26:59 +02:00
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.	2026-07-31 12:18:28 +02:00
jaap-jan	91438fb382	Ask before deleting, and connect a host by double-clicking it ... DELETE on a host, an SSH key, a stored password or a file on the host now puts a question where the button was, and only answering it deletes anything. It is a state rather than a dialog, which is the arrangement signing out already had and for the same reason: this is the moment that has to be able to say what is about to go before it goes. What the question says is counted rather than generic, because a confirmation that only asks whether you are sure is a click to train people out of. A key names the hosts that authenticate with it and says they will refuse to connect afterwards rather than falling back to a typed password, which is what the connect path actually does. A host discloses a terminal open on it, because deleting the host does not close the session. Every vault deletion says how far it travels and whether this machine can push the tombstone yet or is queuing it. Deleting on the host carries the strongest warning of the four on purpose: everything else here is a tombstone against a copy the server still holds, and a file on somebody's machine is bytes with nothing behind them — so that one names the full path, since a bare name identifies nothing. The armed request carries the item's entity id, so nothing that moves the selection between the question and the answer can redirect it, and answering about something that has since gone says so instead of doing nothing quietly. Disarming compares ids rather than rows, which is the subtle half: a reload replaces every row object, so the naive rule would have let the pass that runs every minute take the card away from somebody halfway through reading it. Forgetting a pinned host key is deliberately still unguarded. It costs one fingerprint check on the next connection and it is the safe direction to be wrong in — the dangerous button there is the one that adds trust, and that one is already a prompt at connect time. Discarding a stopped transfer is likewise unguarded: it removes a resumable part file and leaves the source alone. Double-clicking a host in the sidebar connects to it, wired as a gesture in the control exactly as the transfers screen opens a directory. CONNECT stays, since it is the button with the password box beside it. Ten existing delete call sites now go through arm-and-confirm helpers, and eight new flow tests cover asking first, cancelling, the counted warning, disarming on a selection change and on an editor opening, surviving a sync, and the stale-item guard. Three layout tests measure the new shapes — the sidebar card is the one card in the application a user cannot scroll — and one of them also asserts the card renders its text, because a card whose compiled bindings did not resolve would lay out perfectly as empty rows. The double-click test performs the real gesture and proves it reached the connect command through a refusal that never touches a network. dotnet build, dotnet test and dotnet format --verify-no-changes are all clean: 853 tests, including the end-to-end suite against real containers.	2026-07-31 11:52:13 +02:00
jaap-jan	240aadb746	Merge branch 'main' into claude/vault-unlock-logout-autosync-a84c35 ... Four files needed a hand, and all four were two branches adding something in the same place rather than either changing what the other did. The shell's constructor now takes both new parameters: main's SFTP session factory, which it must have because it builds the transfers view model, and this branch's optional resume handler, which stays last so every existing test that constructs a shell without one still gets a shell that can only be online because somebody signed in during this run. App.axaml.cs, ShellFlowTests and QuickConnectTests pass the pair; the layout suite keeps both of its new fields. Signing out now detaches the transfers screen exactly as locking does, and the confirmation says that an open transfer session survives it. That is the same policy both sides already argue for their own case: signing out destroys this machine's copy of the vault, not work that authenticated before it. QuickConnectTests did not compile on main — the SFTP commit added a constructor parameter and the quick-connect suite, merged from a parallel branch just before it, was still calling the old one. Fixed here rather than worked around, since the merged tree has to build. dotnet build, dotnet test and dotnet format --verify-no-changes are all clean: 980 tests, including the end-to-end suite against real containers.	2026-07-31 11:16:49 +02:00
jaap-jan	0b261c4d39	Stay signed in, come back online by itself, and let a machine be given up ... Three things a machine that has been set up could not do. Unlock now takes Enter, which is the gesture everybody makes after typing a password and which did nothing until they found the button. Signing in survives a relaunch. The refresh token is kept in the local cache, sealed under the vault's own cache key, so a later launch resumes the session through the refresh grant with no browser and nobody present — and because it is sealed under that key, only an unlocked vault can resume it. A locked client therefore cannot reach the server at all, which is a consequence worth stating rather than working around; docs/crypto.md §3.2 records it. Every sync pass asks the shell for a connection rather than reading one captured at unlock, so a laptop that unlocked on a train is online within a minute of finding a network, with nothing pressed. Unlocking itself still never waits on a socket. Signing out empties this machine: the profile, the cached items, the outbox and this machine's device key, with the account's row withdrawn when the server can be reached. It asks first and says what it costs — the outbox count when the vault is open, an admission that it cannot be counted when it is not, and the shells that keep running either way. The vault is on the server and is untouched, which is what makes the same button the only honest answer to a forgotten passphrase, so it is on the unlock screen as well as in preferences. It cannot end the session at the identity provider, and says so. Two defects surfaced on the way. The synchronisation pass that runs when the vault opens never ran at all: the loop is started from inside the unlock command, so the busy flag it yields to was raised by that command — the first sync was a minute late on every launch. And signing in from preferences while unlocked threw an unlock screen over an open vault whose keys were still in memory. The unlock card and the new confirmation live in their own controls because MainWindow cannot be laid out headless, so markup left inside it is markup no test can measure; both are now measured at the window's minimum size in the shapes that grow. What is still unverified is the composed window itself.	2026-07-31 11:07:36 +02:00
jaap-jan	04faef6597	Move files to and from a host over SFTP ... M2's file transfer, built bottom-up: an SFTP session on the SSH layer, a transfer queue in a project of its own, and the two-pane browser the design asked for replacing the screen that said it did not exist. Remote listings carry names, sizes, modification times and a real drwxr-xr-x — nothing in this repository could render a POSIX mode before — and the queue moves one file at a time with progress, throughput and resume. The design import assumed this would be an SFTP subsystem channel on ISshConnection, beside the shell on a transport that is already up. SSH.NET does not offer that: SftpClient derives from BaseClient and owns its own transport, and there is no supported way to hand it an SshClient's session. So file transfer opens a second authenticated connection, and it is named for that rather than dressed up as a channel — OpenSftpAsync is on ISftpSessionFactory, not on a connection. The difference is visible to a user: the host records a second login, and a host whose password is typed each time asks for it again on this screen. It goes through the same host key gate, the same pin and the same two refusals a shell does, so a fingerprint approved for a terminal is approved here and one approved here reaches the other machines with the next sync. docs/design-import-gaps.md is corrected, and marked as the one row where what shipped differs from what it predicted. Nothing is written at its final name until it is complete. Every transfer goes to a .dodossh-part file beside its destination and is renamed into place at the end, so an interrupted transfer can never be mistaken for a finished one — which matters most for what this screen is actually for, which is copying a build artefact onto a server and then running it. A destination that already exists is refused outright rather than overwritten: the queue has no way to ask, and silently replacing a file somebody's process is serving is the worse of the two failures. The remote pane has DELETE and MKDIR so that refusal is not a dead end. A test against the container pins the assumption underneath all of this — that SFTP's rename does not clobber. Resume works within a run of the application and not across a restart, and the limit is deliberate rather than unfinished. Nothing records which source wrote a part file, and resuming one on the strength of its name matching is how a corrupt artefact gets delivered with nothing reporting a failure; a part file found at startup is started over. Making it survive a restart needs the preferences store this client still has not got. The offset a resume starts at is the part file's own length rather than the transfer's recorded progress: a cancellation can land between a write completing and the counter moving, and only one of those two is a fact about the bytes that are there. The queue and its connection outlive a lock, as shells do. LockAsync already argues that locking must not destroy work in flight — it is what somebody does when they walk away from the machine, which is exactly when a long transfer is most likely to be running — so TransfersViewModel is created once and the vault is attached on unlock and detached on lock. What locking takes is the host list, and it has to: those rows carry decrypted secrets. DodoSSH.Client.Transfer is a new project rather than more of Client.Ssh. The two answer different questions — one is about reaching a host, the other about moving bytes and what to do when moving them stops halfway — and this is the only client project that deliberately touches the local filesystem. Three defects the tests found, none of which review would have. SftpPath.Name answered an empty string for the root. NavigateRemoteAsync wrapped itself in the busy guard, so navigating from inside another command did nothing at all and the remote pane simply stayed empty after connecting, with no failure anywhere to explain it. And opening an SFTP session per test made two handshakes per test — this client learns a host key by being refused — which pushed the SSH assembly past sshd's MaxStartups and failed a different few unrelated tests each run; the session is shared through the fixture now, with the reason written where the next person will hit it. 1004 tests green across 18 projects, 24 of them new: the SFTP subsystem against the OpenSSH container, the queue against a real temporary directory and a fake host, and three more layout measurements because a screen this window has never laid out is a screen never checked. Not verified: the screen has not been looked at running. The layout harness measures it at the window's minimum in three shapes, which is the class of defect that has shipped here before, but reaching it in the application needs the compose stack, the migrations, the API and a browser sign-in. What is still absent — the status bar's transfer count, dragging between the panes, transferring a directory, and sftp over a bastion — is in docs/design-import-gaps.md.	2026-07-31 11:07:29 +02:00
jaap-jan	9a76eced14	Give hosts and terminals their own screen, and the rest of the vault another ... Rebuilds the client's shell from an imported design: a titlebar and nav rail it draws itself, real multi-session tabs over the one WebView, a Ctrl+K host search, and a vault screen that merges keys, passwords and pinned host keys into one table. Hosts left the vault column for their own screen beside the terminal, which is what the design asks for and turned out to be the better split anyway. Two screens the design shows have nothing behind them yet — file transfer and teams — and say so plainly rather than rendering invented data; every other gap between the design and this build is recorded in docs/design-import-gaps.md.	2026-07-31 08:39:37 +02:00
jaap-jan	211eba0666	Keep host key trust in the vault, and make it withdrawable ... A fingerprint approved once is now approved on every machine and survives a restart, because host key trust is a vault item type rather than a dictionary that dies with the process. InMemoryKnownHostStore was what shipped, so the user was asked to verify a fingerprint on every single connection — which is the gap most likely to train somebody to click through the one warning that actually matters. A warning that appears when nothing is wrong teaches that nothing is ever wrong. The fourth item type, and like the third it cost no sync logic: a row, an EF configuration, a migration, a server kind; a secret, a codec, a merge, a cipher, a repository facade and a session property. One row in the client registry. The reconciler, the mirror, the repository, the outbox and the pull filter were not touched. SyncEntityType.KnownHostKey and AadResourceType.KnownHostKey were already reserved, so neither the contract nor docs/crypto.md changed. One item per (host, port, algorithm), because a server legitimately offers several host keys and which one gets negotiated is not ours to predict. Pinning per endpoint would make an algorithm change indistinguishable from an attack. The label is derived rather than stored, which is the one place this type departs from the other three. A user never names a pin — there is nothing to name it after but the three fields it already has — and a stored label is a second copy of data that can disagree with the first after a merge. Relabel returns the secret unchanged, and says why. The store answers the handshake without touching the disk. SshNetConnectionFactory calls FindAsync from inside SSH.NET's synchronous HostKeyReceived event, over .GetAwaiter().GetResult(), which cannot be avoided; doing SQLite I/O plus an AEAD open per lookup there would put the handshake behind the cache. So decryption happens in OpenAsync and RefreshAsync — on unlock and after each sync pass, exactly where the host and key lists already reload — and FindAsync is a dictionary read under a lock with no await inside it. That snapshot is where the one real bug in this change lived. Install originally merged the live pins over the freshly loaded snapshot, to protect a TrustAsync that had landed while the read was in flight. It would also have resurrected every pin the user had just forgotten, and stopped a withdrawal made on another machine from ever taking effect — the store would have healed the deletion back into existence on every refresh. Replacing wholesale and discarding the read instead is correct because writes are the rare case: every write bumps a generation counter, and a refresh whose stamp is stale throws itself away rather than winning. Nothing found this but reading the method again; it is the kind of mistake that passes every test written before it, because the test that catches it is the one the bug tells you to write. Forgetting is new, and persistence is what made it mandatory rather than convenient. A mismatch is a hard refusal with no way to continue — deliberately, and that stays — so pinning a key permanently is also a way to make a legitimately rebuilt server permanently unreachable. Before this change the pin died at exit and the problem solved itself; now it does not. ForgetAsync drops every algorithm for an endpoint, and it is reachable from the host editor rather than from the warning. Putting it on the mismatch banner would have made it two clicks from "this may be an attack" to "connect anyway", which is the affordance the hard refusal exists to deny. The banner already promised the key could be removed in the host's settings; that promise is now true and points at the button. Trust recorded on another machine becomes visible at the next sync pass, not immediately, and that is a decision rather than an oversight. The failure it produces is a first-contact prompt for a host a colleague approved a minute ago: answerable, and self-correcting on the next pass. The opposite trade — polling the vault on the handshake thread to close a one-minute window — buys nothing and costs the property above. The dangerous direction is not reachable at all: a pin recorded here enters the snapshot as part of recording it, so a refresh can never discard a local trust decision. The server learns nothing, and this is the item type where the temptation was real. A plaintext host column would let a known-hosts screen sort and page without decrypting anything, and it would hand the operator the map of every user's estate — assembled, as these things are, out of facts that are each individually harmless. A host row concedes an address only when relay is switched on and the database refuses to store one otherwise (ADR 0004); there is no equivalent excuse here. The table has no column to put one in, and the EF configuration says so where somebody adding it would be standing. Two things about the migration in this commit are worth knowing, because both came out of getting it wrong. It was hand-written first, including its .Designer.cs, and that version is not what is here. Verifying it turned up something that had been quietly assumed: Migration_AppliedCleanly_WithNoPendingModelChanges does not check the model snapshot. It asserts that migrations applied and that none are pending, which a wrong snapshot satisfies perfectly — the snapshot only matters as the diff base for the *next* migrations add, so an incorrect one passes the whole suite and corrupts the following migration instead. The real check is to generate a throwaway migration and confirm its Up and Down come out empty. They did, and the generated designer was byte-identical to the transcribed one across all 1255 lines, so the hand-written work was in fact correct. Then dotnet ef migrations remove --no-build deleted the wrong migration. With --no-build the tool reads the previously compiled assembly rather than the files on disk, and the probe had just changed which migration was last, so it removed AddKnownHostKeyItem and reverted the snapshot. That turned out to leave exactly the right diff base, so the migration here is EF's own output rather than a transcription — a better outcome than the one that was interrupted, arrived at by accident. Never pass --no-build to migrations remove. Mutation tested, all three sabotages detected: dropping the algorithm from KnownHostIdentity.For, merging instead of replacing in Install, and pointing KnownHostKeyCipher at PortForward — which is what a cast from the wire enum's 10 would silently produce. Each is caught both by an assertion about the mechanism and by a behavioural test that never mentions it; the resource-type sabotage is caught by the table from d10a38d and nothing else, which is what that table is for. The end-to-end slice now approves the real sshd's host key through the vault, pushes it, and reads it back on the second simulated machine — including a check that the server learned no address, and that the second machine answers null for an algorithm never offered. 845 tests green. Zero warnings, dotnet format clean. Three things are deliberately not fixed. A tombstone queued over a create that was never pushed is refused by the server as Invalid and parked; that is pre-existing for all four item types, and the fix belongs in VaultItemRepository.DeleteAsync rather than here. Deleting a host, or changing its address, orphans its pins — both are correct as trust decisions, since a pin describes an endpoint and not a bookmark, but nothing surfaces the leftovers. And there is no interface listing pins at all: trust is created at the connect prompt and withdrawn in the host editor. A known-hosts list is where the orphans would become visible, and it wants the vault column rework first, for the same reason the credential editor does.	2026-07-30 11:00:39 +02:00
jaap-jan	70b3290a77	Bind an SSH key to a host instead of picking one per connection ... A host now names the key it authenticates with, or none, as a field in its encrypted payload — so the choice follows the host to every machine rather than being made again each time somebody connects. The per-connection "Use key" switch it replaces was a stopgap for not having this, and keeping both would have left two mechanisms answering one question. This is the first payload schema version bump, and it does not work the obvious way. A host is written at the *lowest* schema version that can represent it: one that binds a key is written at 2, one that does not is still written at 1, byte for byte as it was before the field existed. The version is what makes an older client refuse to edit an item, so stamping 2 unconditionally would mean upgrading a single machine and renaming a single host made that host uneditable on every machine that had not upgraded yet. Confining the cost to the hosts that actually use the field is the difference between a team noticing a bump and a team being blocked by one. HostSecretCodec states the rule so the next field added follows it, and a test pins the version-1 bytes against a literal rather than against the codec, because the claim is about history: every host already in every vault has to re-encode to what it encoded before, or the first sync after an upgrade would push the whole vault as changed. A binding is an item id, not a copy of the key — a second copy of a private key is one that goes stale — which means the reference can dangle when the key is deleted on another machine. Both places that meets are handled the same way, by refusing rather than falling back: - Connecting to a host whose key is gone is refused outright. A host somebody deliberately set up for key-only access must not quietly start offering a password. - Opening such a host in the editor keeps the binding, selected, labelled as missing. The quieter version of the same failure is someone editing the port and saving, silently converting the host to password authentication with nothing ever having said so. Two things this found by being falsified: - The merge was untested for the new field, and "just take the server's value" passed the entire suite — a local binding change would have been discarded with no conflict recorded. HostSecretMergeTests already had a test written for exactly this class of omission; it simply had not been extended. - Adding a nullable field exposed a defect in HostSecretMerge.Field: it short-circuited when the discarded value was null, so the formatter never ran for the one case where null is a value rather than an absence, and a field whose absence has a name could not report it. Now the formatter always runs, and "no key" appears in the conflict log where an empty string used to. Also fixes eight nullable warnings in SyncEndpointTests left by the server-side SSH key commit, which had omitted the null-forgiving operator the rest of that file uses. They were invisible until an unrelated change forced the project to recompile. The end-to-end slice now binds its host to its key, so a schema-version-2 payload goes through the real API, the real PostgreSQL and back out on a second machine. 745 tests green. Zero warnings, dotnet format clean.	2026-07-29 20:42:51 +02:00
jaap-jan	e3fd3e1728	Sync and authenticate with SSH keys on the client ... Completes the client half of SSH keys: they sync alongside hosts, appear in their own list, and can be selected to authenticate a connection instead of typing a password. The reconciler and the repository were Host-typed throughout, so the choice was to generalise them or to keep a second copy per item type. Generalised, because ItemReconciler's whole premise is that the pull and the push paths must answer the same collision the same way — two copies would drift the first time one of them was fixed. What is genuinely per-type now arrives through IItemKind<TSecret>: the cipher, the merge, the plaintext columns, and the noun to use when telling a person what happened to their item. Generic where the server's IItemKind is not, and for the reason that reverses there — the client needs the concrete type, because it merges field by field. The pull filter is derived from the same registry that builds the reconcilers. That is the specific failure being designed out: an item type that encrypts, merges and lists perfectly and is never once requested from the server, so it works on the machine that made it and exists nowhere else. No client cache migration. The item table's primary key and the outbox's unique index already carry the entity type, and AadResourceTypes already mapped SshKey — so a host and a key may share an id and never see each other's rows, which SshKeySyncTests now arranges deliberately. A key hands the server nothing in plaintext. There is a public_key_fingerprint column and it would be accepted; leaving it null is deliberate. A fingerprint is not secret but it is a stable identifier for a key pair, so filling it would let an operator tell which of their users hold the same key and correlate one across vaults, for a column nothing reads. The design allows itself one plaintext concession — the relay address, which the relay cannot work without — and this is not that. A key is chosen per connection rather than bound to a host, which works the way ssh -i does. Binding one needs a field on HostSecret and therefore a payload schema bump, which makes every host written afterwards read-only on an older build; worth doing deliberately rather than as a side effect of adding keys. Three things this found, all of them by being falsified rather than by review: - Making the reconciler generic silently turned a record comparison into reference equality, because == on a type parameter is not value equality. The effect would have been a conflict recorded on every pass for an unacknowledged create that had in fact landed. Sabotaging the fix left all 73 tests passing — nothing covered that branch — so ConflictMatrixTests now has AnUnacknowledgedCreateThatDidLand_IsDroppedQuietly, which fails without it. - A test asserting that a blank passphrase reaches SSH.NET as null was vacuous: it exercised the editor, not the credential path, and passed with the guard deleted. Resolved by making SshKeySecret.Passphrase normalise an empty string to null, so there is one spelling of one state — which also keeps two clients from producing different payload bytes for an identical key. That exposed a wider gap: SshKeySecret, its codec and its merge had no direct unit tests at all. They have 25 now. - The reason first given for that normalisation was false. It claimed SSH.NET rejects a passphrase supplied for an unprotected key; measured against a real sshd it ignores it and authenticates anyway. Corrected everywhere it was stated and recorded in docs/platform-flags.md. The same test file also closes a real hole: SshPrivateKeyCredential had never been exercised against a server, because the existing key test builds SSH.NET's auth method directly and bypasses the path a vault-held key actually takes. Only one editor may be open at a time. Both sit in the same 340-pixel column as Auto rows and their heights together exceed it at the window's minimum size, so two open editors put the lower one's Save and Cancel past the bottom edge — the same failure this window already shipped once with the setup screens. Expressed as a state rule because that is the only form of it this repository can check: nothing here loads a .axaml. The refusal keeps what was typed, since in the key editor that is a pasted private key the user may have nowhere else. The end-to-end slice now carries a key as well as a host, so both item types go through the real API, the real PostgreSQL and the real crypto in one pass — the three hand-kept mappings between enums that do not line up are the reason that is worth doing rather than trusting the unit suites. 735 tests green, including the container-backed SSH and end-to-end suites. Zero warnings, dotnet format clean.	2026-07-29 20:27:23 +02:00
jaap-jan	5a899afd78	Decide what Lock does to a running shell, and say it ... Pressing Lock nulled and disposed the vault view model and touched nothing else. TerminalWorkspace is injected from App.axaml.cs and outlives every lock, so the SSH connection, the pty and the pump all kept running while the window said "Unlock your vault" — and since 0500e43 collapsed the WebView while locked, that live session was invisible as well as unstopped. CloseSessionAsync was reachable in production only from DisposeAsync, i.e. shutdown. None of this was written down anywhere, so it was neither a policy nor a bug, which is the actual problem. Shells now deliberately outlive the lock, and every layer says so. The reason to prefer this over making Lock a disconnect: locking is what a person does when they walk away from the machine, which is exactly when a long upgrade, build or transfer is most likely to be in flight. Ending every shell would make Lock a button that destroys work, and the predictable response is to stop pressing it and leave the vault open instead. The idle auto-lock this will grow decides it outright — an unattended timeout that killed a running job would be worse than the exposure it removes. Closing the channel also buys less than it looks: the session was authorised at connect time by a credential the remote verified itself, and no vault key participates in keeping it alive, so locking cannot retroactively un-authorise it any more than removing a member can. Stated honestly rather than implied, because the lock screen is what hides it: - The unlock screen shows how many shells are still connected, and that locking closes the vault and not the connections — so a machine still holding authenticated SSH channels does not present itself as merely "locked". Shown only when there is something to disclose. Quitting is what ends them, and the text admits that. - The Lock button carries the same thing in a tooltip, since its name implies the opposite of what it does to a shell. - README lists it as a third architecture consequence beside non-retroactive revocation, which is the same shape of honest limit; docs/crypto.md §10 records it as a threat-model boundary; TerminalWorkspace and LockAsync carry the argument next to the code. LiveSessionCount deliberately does not count dictionary entries. Nothing removes a session when the remote closes the channel by itself — RunSessionAsync only drops the renderer registration — so sessions.Count would report a shell that exited half an hour ago as still running, on the one screen where a user is deciding whether it is safe to walk away. A completed Run task is what "the shell is gone" actually looks like. While locked the number can only fall, since opening a session needs the vault, so a stale value over-reports rather than under-reports. Both new tests fail when the policy is reverted: the count test times out against sessions.Count, and the shell test reports "workspace.LiveSessionCount should be 1 but was 0" when Lock closes sessions. ShellFlowTests also stops building its workspace with a real SshNetConnectionFactory that nothing ever called, which had made the suite's independence from the network a coincidence rather than a property. Verified by hand with a live shell, which nothing had done: a harness mirroring MainWindow.axaml's 340,* grid with a real NativeWebView, the shipped WebAssets, a real sshd in a container, and an ISshShellSession decorator recording every window-change the remote is actually told about. Across lock and unlock, no window-change reached the remote at all, stty size answered 50 118 before and after, the renderer's own buffer came back byte for byte with the wrapped line intact, and the session stayed live throughout. A control run that never hides the WebView behaves identically, so nothing above is startup or idle behaviour. Keystrokes injected while locked reach nothing: twelve of twelve SendInput events accepted with the harness confirmed as the foreground window, no probe character in the remote's output, and a following Ctrl-U answered BEL, so nothing was queued in the line editor either. A hidden WS_CHILD window is not eligible for keyboard focus, which is what makes surviving the lock defensible rather than merely convenient. Correction to a claim made in f80b3d4: terminal.js's guard comment listed "a host that hides the WebView while the vault is locked" among the paths that reach a degenerate fit. It does not. Collapsing the control hides a native child window without resizing it, so the page still reports paneWidth 840 and paneHeight 760 with unchanged cols and rows, no ResizeObserver callback fires and the fit never runs. Establishing that rather than assuming it: the same cycle with MINIMUM_FITTABLE_PIXELS patched to 0 — the guard fully disabled — is equally clean. The guard is still right for minimising and for a splitter dragged to the edge; it is simply not what makes locking safe, and must not be cited as though it were. Recorded, not fixed: - Nothing closes one terminal from the interface, so a user reading "1 shell is still connected" can only act on it by quitting. CloseSessionAsync is tested and correct; VaultViewModel discards the session id it would need. - A session whose remote exits keeps its ISshConnection, and the thread ShellStream parks, until the process ends. - Suspected and seen once: before the harness waited for the window's scale to settle, a DPI settle pushed a 2202x1328 pane for a window 1180 logical units wide and a later re-push reflowed the wrapped line. Three later runs at RenderScaling 1.00 never showed it, so it is filed as a lead, not a finding. - WebView2 fails to initialise with CO_E_SERVER_EXEC_FAILURE when the host executable sits under a very long path. Cost an hour on the harness; relevant to packaging.	2026-07-29 14:44:02 +02:00
jaap-jan	0500e43e02	Stop the terminal's WebView painting over the setup screens ... The shell layered its setup and unlock screens over the terminal, which does not work: NativeWebView attaches a real Win32 child HWND through NativeControlHost, and a child window composites above everything its parent paints regardless of visual-tree z-order. The cards rendered sliced at the terminal column's left edge; at the window's default width every one of their buttons fell inside the WebView's rectangle, so the flow could only be completed by keyboard, and a click in that region handed Win32 focus to WebView2 so the text boxes silently stopped accepting keystrokes. The WebView is now collapsed while the vault is not unlocked. The comment that previously forbade this — hiding it means never realising it — was wrong: NativeControlHost creates the native attachment on attach to the visual tree, never consulting layout or visibility, and NativeWebView replays a Source assigned before its adapter exists. A collapsed WebView still starts WebView2, loads the page and lets the renderer attach. Confirmed: 35 msedgewebview2 processes with the control collapsed. What the first connection after unlocking actually depends on is the existing await on WaitForRendererAsync, since the data plane drops frames when no renderer is attached. Also fixes the second visible defect: the default server URL was https://localhost:7217, the API's *second* launch profile, while the README, its appsettings and a plain `dotnet run` all use http://localhost:5233 — so nothing was listening, and an HTTPS client against a plaintext port reports "The SSL connection could not be established", which reads as a certificate problem. The default now matches, a missing scheme is rejected by name instead of parsing as scheme "localhost", and that specific TLS failure now suggests http://. Both new tests fail when the fixes are reverted. Corrections to claims I made earlier and should not have: - docs/platform-flags.md asserted the opposite of the mechanism above and cited an established msedgewebview2 connection as verification. That observation was taken while the overlay was showing but, because of this very bug, the WebView was uncovered and in plain view — so it confirmed only that a visible WebView is realised. A process-level check cannot verify a rendering claim. The entry was also filed under "Local cache". - ITerminalHost was documented as the live seam the app plugs into, with a stub standing in for headless tests. It has no implementation anywhere and no test uses it; the view navigates the control directly. It also counted Avalonia.Controls.WebView and NativeWebView as two interchangeable backends when they are one component, with the Linux backend backwards. - The README claimed the shell's whole path was covered by tests. Its state machine is; its layout is covered by nothing, and a headless test could not have caught this — headless has no native window, so it would have rendered correctly and confirmed the wrong belief. Verified by screenshotting the running app: the card renders complete and centred at the default size, with the button clickable.	2026-07-29 13:26:30 +02:00
