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.

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. |

Fix the CI formatting gate, which was already failing
dotnet format --verify-no-changes exits 2 on main: the async-suffix naming rule fires on every async test method. I reported this gate as clean when finishing the sync engine and it was not. Test names are documentation. Push_WithAStaleVersion_ReportsConflict says what is asserted; adding Async says the same plus an implementation detail nobody reading a failure report needs. The suffix convention exists so callers can spot awaitables, and a test method has no callers -- so the rule is switched off under tests/ rather than the names being changed. |

Add configuration, OIDC auth wiring and discovery endpoints (M1)
Options, JWT bearer validation, the /meta and .well-known endpoints, and a dev compose stack with Keycloak. Verified end to end: compose up, migrate, run, both discovery endpoints return correct payloads, and readiness reports the schema current. Configuration: - Strongly-typed options for Server, Oidc, Relay and Sync, all ValidateOnStart. A self-hosted server that boots half-configured and fails later per-request is far harder to diagnose than one that refuses to start and names the bad setting. - Cross-field validation the annotations cannot express: relay needs a WebSocketUrl when enabled, idle timeout must be under max session duration, item payload cap under batch cap. - Startup warnings for combinations that are individually valid but dangerous together: RequireHttpsMetadata false outside Development, and AllowEmailLinking (which turns any token bearing a victim's email into account takeover, hence default false). Auth: - JwtBearer with ClockSkew cut to 30s from the 5-minute default; five minutes of slack on a credential granting vault ciphertext access is more than any clock needs. - IncludeErrorDetails off, and a FallbackPolicy so an endpoint without an explicit policy still requires a caller rather than silently being public. Discovery, per ADR 0002: - /api/v1/meta reports versions, features and push caps. - /.well-known/dodossh-configuration is the onboarding story: the user types one server URL and the client discovers OIDC authority, client id, scopes and relay endpoint. Two environment problems found by actually running the stack: - PostgreSQL 18 changed its data mount point. Mounting /var/lib/postgresql/data — correct through 17 — makes the image refuse to start; 18+ wants a single mount at /var/lib/postgresql with the cluster in a subdirectory. - Keycloak moved to host port 18080. An unrelated Apache Tomcat on this machine holds 127.0.0.1:8080, and a loopback-specific bind beats Docker's 0.0.0.0 publish for "localhost". It presents as Keycloak 404ing every realm while its own log says the import succeeded, which is a genuinely misleading failure. Also: CA1848 is enforced, not advisory — warnings are errors, so the .editorconfig comment claiming otherwise was wrong. Startup and health logging now uses [LoggerMessage]. And a clean rebuild is back to zero warnings; the incremental build had been hiding 40 in test projects (banned Guid.NewGuid, an obsolete Testcontainers constructor, and two analyzer families that are genuinely noise under a test host). Verified: 0 warnings on a clean rebuild, 122 tests pass, format clean. |

Freeze DodoSSH.Contracts v0.1 (M1)
The second M1 gate. This assembly, not the OpenAPI document, is the client's contract, so PublicApiAnalyzers now tracks all 540 public members: a renamed DTO property becomes a build error rather than a runtime deserialisation failure on someone's laptop. Contract surface: - EncryptedPayload carries the envelope plus the KeyGeneration and AadVersion columns needed to recompute AAD, since AAD is derived from the row rather than transmitted. - Sync: push with per-operation status (Applied/Conflict/Forbidden/Invalid/Duplicate) so one stale item cannot block a whole offline queue; a Conflict returns the server's row for client-side three-way merge, because the server cannot merge ciphertext. - Enrollment: KeyStatement whose hash becomes the OIDC nonce, so the identity provider signs over the public keys and this server cannot fabricate a key for a user who never enrolled. - Meta and .well-known configuration: capability negotiation instead of URL versioning, which is what a self-hosted product needs when client and server upgrade independently. - SyncPlaintextFields deliberately has no label or name field. ACL admin runs client-side where names can be decrypted, so the server never needs a searchable title. Two design problems found by writing the tests rather than assuming: - Hand-constructing JsonSerializerOptions and merely pointing its resolver at the context silently discards every source-generated setting. JsonSerializerDefaults.Web replaces NumberHandling.Strict with AllowReadingFromString, so "1" would be accepted where 1 is meant — invisible until two implementations disagree. Callers now use ResponseOptions or StrictRequestOptions; StrictRequestOptions is derived by copying so it cannot drift. - StrictRequestOptions had a static-initialisation cycle: it read the generated Default property from the same type's initialiser and got null. Now lazy. Requests reject unmapped members so a client typo is a 400; responses tolerate them so an older client can read a newer server. Enums cross the wire as strings, so reordering one cannot silently reinterpret stored data. Also: excluded source-generator output from PublicApiAnalyzers. The JSON generator emits a public member per serialisable type, which would have added hundreds of mechanical entries and drowned the ones describing the actual wire contract. And disabled MA0048's one-type-per-file rule: splitting SyncPullRequest from SyncPullResponse makes a reviewer open two files to understand one endpoint. Verified: 0 warnings, 95 tests pass, format clean. |

Freeze DSH1 crypto specification and implement the core (M1)
docs/crypto.md is now the normative, frozen specification. This had to land before anything else in M1: the server holds ciphertext and no keys, so it can never re-encrypt, and a format change after users hold data is a coordinated client rewrite with no rollback. Specification: - DSH1 envelope layout, canonical 64-byte AAD encoding, SealTo construction, key hierarchy, Argon2id profiles, fingerprints, and the change rules for each version field. - AAD encoding is fixed-width binary rather than delimited string concatenation, so no field value can forge a field boundary. This supersedes the illustrative form sketched in ADR 0001, which now points here. - UUIDs are RFC 4122 big-endian. Guid.ToByteArray() emits the first three groups little-endian and would have made our ciphertext unreadable by any other implementation of this spec, failing only at a cross-implementation boundary. Verified rather than assumed: - PrimitiveAvailabilityTests proves X25519, Ed25519, XChaCha20-Poly1305, Argon2id and HKDF-SHA512 all function on net10.0. NSec 26.4.0 targets net9.0 and is consumed by forward compatibility; this closes one of the two package questions the plan flagged. - Argon2Profile exists because NSec's MemorySize is in KIBIBYTES, not bytes. Passing bytes gives either a 256 GiB allocation or a 256 KiB KDF that cracks instantly. The type takes mebibytes so the unit cannot be got wrong at a call site. Found by benchmarking: the first measurements were ~1000x too slow, which turned out to be 19 GiB of work. - Parameters measured, not guessed: 256 MiB/t=4 is 323 ms on this machine; the table of candidates is in the spec. Implementation and tests (83 total, up from 17): - AadDescriptor, DshEnvelope, DshCrypto (Seal/Open/SealTo/OpenSealed/fingerprints). - Decryption returns null rather than throwing: ciphertext comes from a server that is explicitly not trusted, so a failed tag is an expected outcome. - Envelope readers reject unknown algorithms and any non-zero flag bit, so an envelope that is not fully understood fails closed. - Executable form of the spec's substitution claims: a server cannot move ciphertext between resources, roll back a key generation or item version, repurpose a payload as metadata, or confuse the two constructions. - Golden vectors in tests/fixtures/crypto/vectors.json guard the format. Mutation-checked: a one-byte schema version change trips four tests including the guard. Two build-infrastructure bugs found and fixed along the way: - .editorconfig forced camelCase on const and static readonly fields. PascalCase is the .NET convention for both; the config was wrong, not the code. - The golden fixture was resolved with [CallerFilePath], which ContinuousIntegrationBuild rewrites to /_/... under deterministic source paths. It passed locally and would have failed only in CI. Now copied to the output directory and read from there. |

Restructure into src/tests and add build foundation (M0)
Moves the scaffold to src/DodoSSH.Api and establishes the repo conventions the rest
of the milestones build on.
Structure:
- src/{Contracts,Crypto,Domain,Infrastructure,Api}, tests/{Contracts,Crypto,Domain}.Tests
- DodoSSH.slnx rewritten with src/ and tests/ solution folders
Build:
- Directory.Build.props centralises TFM, nullable, deterministic builds and
TreatWarningsAsErrors; Directory.Packages.props pins every version centrally
- packages.lock.json committed so CI restores in locked mode
- NuGet.config clears machine-level sources, which both fixes NU1507 under central
package management and makes restore reproducible off this machine
- Microsoft.OpenApi pinned to 2.11.0: ASP.NET Core 10.0.10 resolves 2.0.0, which is
covered by GHSA-v5pm-xwqc-g5wc (high, patched in 2.7.5)
Analyzers:
- AnalysisLevel is Recommended, not All. With warnings-as-errors, All turns opinionated
naming rules into build breaks and trains people to blanket-suppress.
- BannedSymbols.txt bans DateTime.UtcNow (TimeProvider), Guid.NewGuid (CreateVersion7),
sync-over-async, MD5/SHA1, PBKDF2 and SecureString
- CA1711/CA1724 disabled: both are .NET Framework CAS-era naming rules
- PublicApiAnalyzers on Contracts only, since that assembly is the client's real contract
API:
- weather-forecast template removed
- UseHttpsRedirection removed; TLS terminates at the reverse proxy and redirecting
behind one causes loops
- /healthz/{live,ready,startup}. Liveness deliberately checks no dependencies so a
transient database outage cannot restart the container and kill live SSH sessions.
Notes:
- No coverage collector yet. Microsoft.Testing.Extensions.CodeCoverage pulls an MTP 1.x
MSBuild extension that throws TypeLoadException against the MTP 2.3.x xunit.v3 brings.
Coverage gates are an M3 concern; revisit with an MTP 2.x-aligned version then.
Verified: dotnet build (0 warnings), 17 tests pass, format check clean, API serves
health and OpenAPI endpoints.
