 ## Validation
 
-Every asset was validated against the **`Robotics-Prop` profile, version `4.0.0`**, following the [SimReady Central guidance](https://docs.omniverse.nvidia.com/simready/latest/simready-central.html). Validation evidence is included in this dataset under `reports/`.
+Every asset was validated against the **`Robotics-Prop` profile, version `4.0.0`**, following the [SimReady Central guidance](https://docs.omniverse.nvidia.com/simready/latest/simready-central.html). Each asset carries its own evidence under `<asset>/.metadata/`.
 
 ### Schema validation
 
-`simready-validate` — **50 / 50 assets pass** with no blocking failures. Per-asset reports are in `reports/validation/`.

 ### Runtime tests
 
-`simready-benchmark 2026.8.0.post1` on **NVIDIA Isaac Sim 6.0.1 (PhysX)** — **37 / 50 assets pass**, with 546 of 575 individual tests passing (16 failed, 13 skipped). The complete run directory, including videos, logs and per-test results, is in `reports/runtime/`; start from `reports/runtime/index.html`.
+`simready-benchmark` on **NVIDIA Isaac Sim 6.1.0.0**, run against both the **PhysX** and **Newton** engines — **33 / 50 assets pass every test**. Across 1,025 individual tests: **945 pass, 62 fail, 18 skipped**. Per-asset results: `<asset>/.metadata/<asset>_benchmark.json`.
+
+#### Engine crashes
+
+Five assets fail every Newton test because the engine session terminated before the tests could run (`Engine session ... crashed before the test could complete`): `fire_extinguisher`, `lancable`, `power_strip`, `respirator`, `safety_goggles`. These account for 45 of the 62 failures. The same five assets pass every PhysX test.
 
 #### Known failures
 
 | Test | What it checks | Assets |
 |---|---|---|
-| `culling_xz` | the asset is rotated under diagnostic shading to catch inverted normals or single-sided geometry | `frame_cart`, `handtruck` |
-| `ground_drop` | the asset is dropped onto a ground plane and must neither penetrate it nor keep moving | `handheld_welding_shield`, `ladder`, `office_chair`, `roller_conveyor`, `safety_goggles`, `weelbarrow` |
-| `slope_drop` | the asset is placed on a 45° ramp and must slide without penetrating the surface | `a_frame_sign`, `handtruck`, `roller_conveyor`, `safety_cone`, `steel_drum`, `storage_rack`, `traffic_cone`, `weelbarrow` |
-
-`safety_goggles` is listed under `ground_drop` because the engine session crashed during that test, not because the asset penetrated the ground.
