 Real AutoCAD smoke tests are ignored by default. Run them serially because they share one AutoCAD document:
 
 ```powershell
-cargo test --manifest-path src-tauri\Cargo.toml smoke_test_round_trip -- --ignored --nocapture --test-threads=1
+cargo test --manifest-path src-tauri\Cargo.toml isolated_safety_scenes_smoke_test_round_trip -- --ignored --nocapture --test-threads=1
 ```
 
+The isolated safety smoke harness assigns a stable grid origin and expected bounding box to each case, refuses an occupied target region, records newly created handles and object snapshots, and erases only those handles after verification.
+
 The evidence gate has a network-free, AutoCAD-free walkthrough in
 `workflows/evidence_gate_offline_demo.md`.

 真实 AutoCAD smoke 测试默认被标记为 ignored。运行时必须串行，避免多个测试共享同一个 DWG 文档互相污染：
 
 ```powershell
-cargo test --manifest-path src-tauri\Cargo.toml smoke_test_round_trip -- --ignored --nocapture --test-threads=1
