Clear the SSH gate: window-change reaches the remote, and licence as MIT
Licence is MIT, set solution-wide rather than only on the packable project: DodoSSH.Contracts is published so clients can build against it, and a package with no licence expression is one a corporate policy scanner rejects outright. The SSH.NET spike is the M1 client gate and it passes. SSH.NET 2025.1.0 exposes ShellStream.ChangeWindowSize, but a method existing is not the remote observing it, so the tests read `stty size` back from a real sshd after resizing rather than asserting the call did not throw. Repeated resizes each take effect too, which matters because dragging a window edge produces a stream of them. The IChannelSession fallback is not needed. Also verified against a real sshd: password and public-key auth, that the host key arrives as a raw blob we can fingerprint ourselves rather than reading SSH.NET's MD5 property, and that refusing the key via CanTrust actually aborts the connection -- without which the TOFU dialog would be decoration. Kept as a permanent suite, not deleted after the spike. An upgrade that silently stopped sending the request would present as wrapped output only after a resize, which is easy to misattribute to the terminal emulator. Two bugs in the test itself, both worth naming because either would have been read as "resize does not work": - A PTY emits CRLF, and the anchored regex rejected the CR. The output visibly contained `24 80` while the match failed. - Each read can begin with output still buffered from the previous command, including its size line. Taking the first match would have reported the pre-resize size. platform-flags.md now records window-change as resolved rather than unverified -- a stale flag is worse than none -- plus the three real SSH.NET limits found on the way: ShellStream does not override ReadAsync so every idle session parks a pool thread, one connection cannot serve both SshClient and SftpClient, and agent forwarding needs an upstream change. |

Add HTTP integration harness and the sync authorization matrix (M1)
27 end-to-end tests over the real HTTP pipeline, against a PostgreSQL container and a stubbed identity provider. This closes the gap the previous commit flagged. Authentication is genuinely exercised, not bypassed. StubIdentityProvider serves real OIDC discovery and JWKS via WireMock and signs tokens with a real RSA key, so the application's own JwtBearer pipeline validates issuer, audience, signature, lifetime and claims. A TestAuthHandler that short-circuits authentication would hide exactly the claim-mapping mistakes that cause real authorization holes. Proven by rejecting: no token, a foreign signing key, the wrong audience, the wrong issuer, and an expired token. Authorization denials — the tests that matter most: - Another user's vault is 404, not 403, for both pull and push. A distinct "exists but forbidden" answer is an existence oracle for other tenants' vault ids. - A denied push writes nothing: no host row and no change-log entry. A denial that still mutated state would be worse than no check at all. - A team vault is denied until M3 rather than falling through to a permissive default. Behaviour covered: push/pull round trip, cursor advance (and that an empty pull does not rewind the cursor, which would replay history), tampered cursor rejection, stale-version conflict returning server state without overwriting, operation-id replay reported Duplicate and applied once, a mixed batch applying the good and reporting the bad, relay field enforcement both ways, delete clearing the relay address, tombstones carrying no payload, and JIT provisioning happening exactly once. Two configuration problems found by running it: - appsettings.json carried empty-string placeholders for the connection string and OIDC authority. Under minimal hosting those beat anything a test registers via ConfigureAppConfiguration, because Program.cs adds its own sources after that callback runs. Removed them outright — an empty placeholder turns "not configured" into "configured as empty", which defeats failing fast. Tests now use DODOSSH_ environment variables, which Program.cs adds last. - My first fix for minting an expired test token derived notBefore from the expiry, which put nbf fourteen minutes in the future for normal tokens and made every valid token 401. It needs the earlier of now-1min and exp-1min. Verified: 0 warnings on a clean rebuild, 173 tests pass (up from 146), format clean. |

Add data model, DbContext and initial migration (M1)
Schema for identity, vaults, grants, hosts and the sync change log, verified against a real PostgreSQL 18 container rather than an in-memory provider: partial unique indexes, CHECK constraints, citext and identity-always columns are all provider behaviour that an in-memory fake would not exercise. Invariants pushed into the database, so they hold even when application code has a bug: - ck_host_relay_target is a security boundary, not tidiness. A host may carry a plaintext hostname and port ONLY when relay is deliberately enabled. Both directions are tested; the important one is that relay-disabled hosts cannot carry an address, since otherwise a bug would silently give the server infrastructure visibility it was never granted. - ck_vault_owner: exactly one of owner_user_id or team_id, or permission resolution would have no defined answer. - ck_vault_key_grant_recipient: member grants name a user; recovery and escrow grants are wrapped to a key and must not. - ck_user_key_wrap_kdf: a password-derived wrap without its parameters is permanently unopenable, so a partial write is rejected outright. Present from the first migration on purpose: - GrantKind (Member/Recovery/Escrow). Recovery cannot be bolted on later — every vault created before it existed would be unrecoverable by design. - team and team_membership, though team features are M3. Adding them later would mean introducing a foreign key on a live vault table. - Host.ContentKeyId, reserved for per-item content keys wrapped to individual users. - user_key as its own table, so key rotation does not require altering the user row. Two things verified rather than assumed: - Npgsql's UseXminAsConcurrencyToken helper no longer exists in EF 10, so xmin is mapped directly in XminConcurrency. The generated migration *looks* like it creates an xmin column; it does not. Confirmed by inspecting pg_attribute (attnum -2, a system column) and by grepping the emitted DDL. A test pins both, because had it created a real column PostgreSQL would have rejected the name. - EF Core is now pinned centrally. The Npgsql provider asks for 10.0.4 while EntityFrameworkCore.Design pulls 10.0.10, and because Design is PrivateAssets=all that higher version does not flow to referencing projects — producing a CS1705 in any test project referencing Infrastructure. Also commits artifacts/schema/v0.1.sql, the idempotent script, as the baseline for future upgrade tests. Verified: 0 warnings, 122 tests pass (27 new against Postgres), format clean. |

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.

Add pristine dotnet new webapi scaffold
Baseline commit of the untouched template so the M0 restructure lands as a reviewable diff rather than appearing as the initial state. Includes .gitignore and .gitattributes only; no source changes. |
