# Test Status

## Failing Tests

No known failing tests.

## Flaky Tests

No known flaky tests.

### Medium — May fail on very slow systems or under extreme CI load

| Test | File | Root Cause |
|------|------|------------|
| Route/Gateway/LeafNode propagation tests (20+ tests) | `RouteGoParityTests.cs`, `GatewayGoParityTests.cs`, `LeafNodeGoParityTests.cs` etc. | `await Task.Delay(50)` polling loops waiting for subscription/route propagation. Timeout can be exceeded under extreme load. |
