-# Welcome to NdotLight SimReady Assets
-
-A collection of OpenUSD assets from **NdotLight**, prepared for robotics simulation, training, and evaluation in **NVIDIA Isaac Sim**.
-
-The initial collection comprises **50 template assets**, including rigid-body, articulated, and deformable objects for industrial and workshop environments.
-
-## What's Included
-
-| Asset type | Examples |
-| --- | --- |
-| Tools | Power drill, screwdriver, hammer, wrench, pliers, and calipers |
-| Material handling | Carts, handtruck, pallet, and roller conveyor |
-| Storage and containers | Storage rack, cabinet, container box, and steel drum |
-| Safety equipment | Safety cones, barriers, machine guard, and protective equipment |
-| Deformable objects | Selected cable and flexible-component assets |
-
-Simulation capabilities vary by asset. Refer to the individual asset's configuration and validation evidence for supported behavior.
-
-## Getting Started
-
-1. Browse [Files and versions](https://huggingface.co/datasets/NdotLight/SimReady_Assets/tree/main) and download the asset package you need.
-2. Keep the USD files and their referenced materials, textures, and other dependencies together.
-3. Open or reference the asset's entry-point USD in NVIDIA Isaac Sim.
-4. Review the asset's physics configuration and test conditions before integrating it into your simulation.
-
-## Validation
-
-NdotLight has completed validation of the initial 50 assets following the [SimReady Central guidance](https://docs.omniverse.nvidia.com/simready/latest/simready-central.html).
-
-For reproducible evaluation, use the validation profile and version, runtime test environment, and results associated with the asset release. Validation covers the documented test conditions; suitability for a specific robotics task should be evaluated in the target environment.

-
-## About NdotLight
-
-NdotLight creates 3D assets and tools for simulation workflows. This collection provides representative assets for developers to explore and evaluate in their own environments.
-
-Visit our [Hugging Face organization](https://huggingface.co/NdotLight) for updates. For questions or issues with this collection, please open a discussion in this dataset repository.

+3. Open or reference the asset's entry-point USD in NVIDIA Isaac Sim.
+4. Review the asset's physics configuration and test conditions before integrating it into your simulation.
+
+## 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/`.
+
+### 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`.
+
+#### 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.
+
+#### Skipped tests
+
+| Test | Assets | Why |
+|---|---|---|
+| `joint_movement` | `crowbar`, `hammer`, `paint_bucket`, `power_strip`, `scraper`, `screwdriver`, `signal_tower`, `storage_rack` | asset has no movable joints, so the test does not apply |
+| `pivot` | `crowbar`, `hammer`, `scraper`, `screwdriver`, `spanner` | advisory check: the pivot/origin score is below the recommended threshold. The benchmark reports this as skipped rather than failed while the specification clarifies whether VG.025 is mandatory |
+
+Physics runtimes other than PhysX are not claimed by these assets.
