Keep the stub servers on loopback
Running the tests raised a Windows Firewall prompt, and raised it again from every worktree. WireMockServer.Start() with no settings listens on 0.0.0.0 and [::], and the prompt is keyed to the binary that opened the socket — so each test executable asks once per bin path, which a new worktree or a switch between Debug and Release makes new again. The three suites that hold a firewall rule on this machine are exactly the three that use WireMock; every other listener in the repository already binds 127.0.0.1. The stubs now say so explicitly. Port 0 is still WireMock's own free-port search and still comes back on server.Url, which is what each stub builds its base URL from, so the authority the API validates against and the issuer its tokens claim follow the binding rather than being pinned to a host name. Sampling the listening sockets of a full DodoSSH.Api.Tests run afterwards finds one, 127.0.0.1, where there were previously three. |

Wire the Avalonia shell to the vault
The host list now comes from the vault instead of from a form. A fresh machine takes a server URL, signs in through the browser, enrolls, and from then on opens with the passphrase alone. DodoSSH.Client.Session is the composition layer: where a profile lives, how it unlocks, and how a machine gets one. ClientPaths picks a non-roaming per-OS directory — %LOCALAPPDATA% and never %APPDATA%, because a SQLite cache that roams between two machines is a corrupt one, and each machine's outbox is its own. SessionOpener needs no transport at all and could not reach one if it wanted to; that is the offline unlock, asserted rather than asserted about. A wrong passphrase, a stale KDF and a grant revoked by a rekey are three different answers, because the remedies are three different things and telling someone to retype a passphrase that was never the problem is worse than saying nothing. The shell's states are the onboarding story. The recovery code gets its own state that cannot be clicked past: it exists for one moment, losing it with the passphrase loses the vault, and there is no server-side reset by design. It is dropped from memory on confirmation rather than merely hidden. Sign-in is a delegate over IVaultServer, so the whole state machine runs in a test against an in-memory server — no browser, no identity provider, no toolkit. The view models are plain observable objects, which is what makes that possible. What it does not cover is whether the XAML binds to the right names; that needs a rendered tree and Avalonia.Headless, and is its own piece of work. Three things found by doing it rather than by reading it: - Pooled SQLite connections keep the database file open after the last context is disposed. On Windows that means locked, so the application could never replace its own cache — and a test could not clean up after itself, which is how it surfaced. Dispose now clears the pool. - EF's SQLite provider puts the database in WAL mode, so the cache is three files. A comment in ClientCacheFactory claimed the opposite; reading PRAGMA journal_mode off a real launch settled it. WAL is the right mode here — a sync pass writes while the interface reads — so the comment was wrong on the merits as well as on the fact. - Enrolling a device key with nowhere to keep the private half would put a wrap on the server nobody can open and make the device list claim this machine can unlock without a passphrase. Device binding is now optional and the shell declines it until the OS keystore is wired. Verified on Windows: the client created %LOCALAPPDATA%\DodoSSH\cache.db and migrated it on first launch, and msedgewebview2 held an established connection to the data plane while the unlock overlay covered it — which is the point of covering the WebView rather than collapsing it, since a NativeWebView that is never laid out is never realised. 630 tests, up from 593. The recovery-code gate and the offline unlock were each verified by breaking them and watching the right test fail. Still to do for M1's actual definition of done: the manual run against the real API and a real Keycloak. Credentials are not a synced entity type yet, so a connection still asks for a password, and the interface says so rather than implying otherwise. |

Add the encrypted local cache and the sync client
Three new client projects, and the wire-contract fix they needed. DodoSSH.Client.Domain holds the decrypted item model and the three-way merge, with no I/O at all — so the suite that decides whether a credential can be lost runs in milliseconds with nothing to mock. Scalars defer to the server on a genuine clash so every replica resolves the same triple identically and two clients cannot ping-pong; directives merge per name so two people each adding one both keep theirs; the jump chain merges as a whole value because its order is the route. Whatever loses is returned rather than dropped. DodoSSH.Client.Storage is EF Core on SQLite, no SQLCipher: the rows are already ciphertext, so an encrypted file would protect protected bytes at the cost of a native dependency. It keeps the server's state and the outbox in separate tables, which is what preserves the common ancestor a merge needs. One pending operation per item, enforced by a unique index. DodoSSH.Client.Sync is the pull/apply/push loop. Pulling never decrypts — a change with no local work pending is plumbed as ciphertext — so a first sync of thousands of items does not run twice as many AEAD operations for nothing. Contracts: EncryptedPayload gains WrappedDataKey and DataKeyId. The specification has required a per-item data key since crypto.md §3, the columns have existed since the first migration and DshAad.ItemPayload binds the id, but this record had nowhere to put either — so a spec-compliant item could not be transmitted at all. Found by writing the client that has to produce one. Also closes a hole in AadResourceType, which had no value for the HostTag and HostCredential that SyncEntityType has always listed. Four bugs the tests found, not review: - SQLite refuses to order or compare its own DateTimeOffset mapping, and throws at execution rather than model build. Collecting tombstones and listing conflicts are both that shape, so this was a crash waiting for the first user with a deleted host. Timestamps are integers now, by convention so a later field cannot be the one left unconverted. - SQLitePCLRaw 2.1.11, which EF resolves, is covered by GHSA-2m69-gcr7-jv3q. Pinned forward as a family. - Resurrecting content from a remote deletion cleared the original before queueing the copy. Two transactions, so a crash between them lost the work; reversed, and the rescued id is derived from the tombstone so a replay coalesces instead of duplicating. - Several equality assertions went through Shouldly's ShouldBe, which compares IEnumerable element-wise and so tested nothing about the Equals these types exist to provide. Corrected; the falsification that caught it went from 2 failures to 6. The push response's cursor is deliberately ignored. It sits after this client's own writes, so adopting it skips anything another client committed at a lower sequence in the window between a pull and a push — permanently. Re-reading one's own writes is idempotent and costs a page. The Contracts doc that invited the shortcut now says so. 593 tests, up from 448. The delete-versus-edit rules, the ancestor retention, the fresh operation id on coalesce and the cursor safeguard were each verified by breaking them and watching the right test fail. |

Add the server client and client-side enrollment
A typed client over DodoSSH.Contracts, and the orchestration that turns a passphrase into an enrolled identity: generate keys, have the identity provider sign over them, wrap the bundle three ways, create the personal vault, publish. Ordering here is forced, not chosen. The secret bundle's AAD binds to the server-assigned user id, so /me has to be read before anything can be wrapped -- which is exactly why /me provisions the account and returns its id even while reporting that enrollment is required. That constraint was designed into the server earlier; this is the first code that depends on it. The grant tuple now has a real canonical encoding (crypto.md 7.3) rather than the placeholder signature I would otherwise have had to invent and then keep. §7 named the tuple without specifying how to encode it; this fills that in with the same conventions as 7.1, and the self-grant at enrollment is already in its final format. The signature covers SHA-256(wrappedKey) rather than the key, so a verifier can check attribution without holding the vault key at all. The most valuable tests are the negative ones about the request body: the server is meant to be unable to read what it stores, and a refactor that put a passphrase or a private key into the enrollment request would be invisible to every other test in the repository. So one asserts the body contains neither the passphrase, the recovery code, nor any private key in base64 or hex. Another opens the same bundle three ways -- passphrase, recovery code and device key -- which is what makes a passphrase change a one-row update. ClientEnrollment depends on IKeyBindingAuthorizer rather than the whole OidcClient. It needs exactly one capability, and depending on the full client would drag discovery and token exchange into every test of key binding. Two things fixed while building it. The recovery code buffer was sized one separator short, so every enrollment threw IndexOutOfRange -- caught immediately because nine of ten tests failed identically. And the crypto enum collided with Domain.GrantKind in the server, so it is GrantPurpose there; the numeric values still have to match, which the doc and a test both say. 448 tests pass, zero warnings on a clean rebuild, format clean. |
