|
|
- **Time**: 10-15 minutes (full suite)
|
|

## Known Issues
|
|
|
|
### Compilation Warnings
|
|
```
|
|
⚠️ nanosecond-scheduler: unused import `tokio::sync::mpsc`

|
|
⚠️ temporal-neural-solver: unused field `max_solving_time_ms`
|
|
⚠️ strange-loop: unused imports (VecDeque, etc.)
|
|
⚠️ strange-loop: unused fields (temporal_comparator, etc.)
|
|
⚠️ meta_bench: unused `mut` in benchmark
|
|
```
|
|
|
|
**Impact**: None - cosmetic warnings only
|
|
**Action**: Can be fixed with `cargo fix --allow-dirty`
|
|
|
|
### No Critical Issues
|
|
- ✅ No compilation errors
|
|
- ✅ No blocking dependencies
|
|
- ✅ All tests should pass
|
|
- ✅ All benchmarks should run successfully
