# Async Module Split Review

## Scope

- Issue: #42
- Milestone: 0.2.0
- Changed surface: `bluetape-rs-async` source layout

## 7-Tier Review

| Tier | Result | Evidence |
| --- | --- | --- |
| Module structure | Pass | `lib.rs` is a facade over focused `control` and `task_group` modules. |
| API compatibility | Pass | Public names remain re-exported from `bluetape_rs_async::*`; crate tests and doctests pass. |
| Behavior | Pass | Existing async unit, integration, workspace, and all-feature tests pass. |
| Documentation | Pass | Public Rustdoc remains with crate facade and focused implementation modules; rustdoc warnings are denied. |
| Risk | Low | Refactor-only split with unchanged public API. |

## Findings

- P0: 0
- P1: 0
