# Deterministic Async Tests Review

## Scope

- Issue: #23
- Milestone: 0.2.0
- Changed surface: `bluetape-rs-async` integration tests

## 7-Tier Review

| Tier | Result | Evidence |
| --- | --- | --- |
| Determinism | Pass | Timeout test uses paused Tokio time; stress tests use bounded ranges and explicit concurrency caps. |
| Concurrency stress | Pass | Integration test runs 64 operations with max concurrency 4 and asserts peak concurrency never exceeds the bound. |
| Leak guard | Pass | First-error integration test verifies started sibling futures are dropped after abort/drain. |
| Test support reuse | Pass | Shutdown test uses `bluetape-rs-test::eventually` and `consistently`. |
| Runtime boundary | Pass | Tests stay on Tokio test runtime and do not spawn blocking work. |
| Scope control | Pass | No public API change; dev-only dependency on `bluetape-rs-test`. |
| Risk | Low | Test-only coverage and review artifact. |
