Priority: ➖ Normal — Schedule this NIP-77 reconciliation change because it broadens the public API with RelayAuth policies, connection-key routing, authentication retries, and related error handling. Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change adds identity-aware relay authentication to NIP-77 reconciliation, but unresolved connection-routing and timeout-accounting behavior could incorrectly end a reconciliation or let it exceed its requested timeout.

Send an AUTH challenge for negentropy-only authentication.
When only requireAuthForNegentropy is true, MockRelay sends no initial AUTH challenge. The NIP-77 retry calls authenticateConnection, which waits for a challenge until authChallengeTimeout and then fails.
Include requireAuthForNegentropy in the initial AUTH-challenge condition.

Register cleanup with addTearDown after each resource is created.
If an expectation or setup step fails, the trailing cleanup calls are skipped. MockRelay.startServer() then leaves its fixed port bound, and Ndk can retain active resources. Register teardown callbacks immediately after creation. The callbacks run after failures, in reverse registration order.

…uture A `require` naming an account that cannot sign was answered by completing the session's completer with an error, synchronously, before `reconcile` had returned the response the caller listens to. Nothing was attached to that future yet, so the error reached the zone as an unhandled one and crashed a caller that only read `response.future` after an await.
A negotiation refused for auth-required retries on a bound connection, and the time that takes was counted against the reconciliation timeout. Signing is the part that hurts: a remote signer waits for a human, so a bunker tap alone could outlast the 30s budget and time out a session the relay never got a chance to answer.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Preserve the reduced timeout budget after a resume.
When an unauthenticated NEG-OPEN is refused, the authentication retry can pause and resume the timeout. A subsequent refusal can pause it again. Because _startTimeout(remaining) does not update _timeoutDuration, the second pause subtracts elapsed time from the original duration and restores consumed budget. Update _timeoutDuration when _startTimeout starts the timer.
Proposed fix
void startTimeout(Duration duration, void Function() onTimeout) {
- _timeoutDuration = duration;
_onTimeout = onTimeout;
_startTimeout(duration);
}
void _startTimeout(Duration duration) {
+ _timeoutDuration = duration;
_timeoutStartedAt = DateTime.now();
_timeoutTimer = Timer(duration, () => _onTimeout?.call());

A remote signer answers a refused request by throwing, and nothing caught that. The exception escaped an unawaited future.
