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. |

Add /me and enrollment with the identity-provider key binding (M1)
The last backend piece of M1. A client can now log in, discover it must enroll, publish its identity key, and get a usable personal vault. Enrollment is one indivisible act. One transaction writes the key, its wraps, the device, the key log entry, the vault and the vault key grant, because none of them is useful alone: a key with no vault leaves a user unable to store anything, and a vault with no grant is a container nobody can ever open -- including its owner, since only the client can wrap the key and it has already moved on. Two independent checks run, and neither substitutes for the other. The Ed25519 self-signature proves possession of the private key. The identity-provider binding proves whose key it is: the client hashed its statement, used the hash as an OIDC nonce, and the resulting ID token is the provider's signature over exactly those public keys. This server cannot mint that signature, so it cannot invent a key for a user who never enrolled -- which is the attack that would otherwise let an operator read every vault by publishing its own key as yours. The binding token is stored verbatim, not just summarised. Clients must repeat the check against the provider's JWKS fetched directly, and storing only our conclusion would ask them to trust the server about the one question the design exists to avoid trusting it about. Key log appends take a deployment-wide advisory lock. The falsification matters more than the passing test: with the lock removed, Enroll_ConcurrentEnrollmentsByDifferentUsers_LeaveAnUnbrokenChain fails with entry 11 linked to the wrong predecessor. Different users trip no unique index, so without serialising they all read the same head and the chain forks -- indistinguishable from the key substitution the log exists to make detectable, and permanent, because the log is append-only. Enrollment is idempotent. Vault ids and keys are client-chosen, so a client whose response was lost re-sends the identical body and gets the identical result. Without that, a lost response leaves a user enrolled against a vault they never learned the id of. Contract change, breaking the v0.1 freeze deliberately. EnrollmentRequest had DevicePublicKey but no wrap to go with it, which is unsatisfiable: only the holder of the secret bundle can seal it, so the server could never fill the gap. Added DeviceWrappedPrivateKey, and PersonalVault so enrollment can be atomic rather than leaving an unopenable vault behind two endpoints that do not exist yet. No client exists and no package is published, which is exactly when PublicAPI.Unshipped.txt expects this. Sync now requires the Enrolled policy, which until now was a stub whose name promised a check it never made. The sync denial tests use enrolled intruders instead of unenrolled ones -- an unenrolled caller is stopped before the vault check runs, which would have left those tests passing without exercising the thing they exist to prove. Also fixed: omitting kdfParameters from the JSON body was a 500. A record's non-nullable parameters are a compile-time promise, not a runtime one. 268 tests pass, zero warnings on a clean rebuild, format clean. |

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. |
