-# 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
-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 output: `<asset>/.metadata/<asset>_validation.json`.
-### Runtime tests
-`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 |
-|---|---|---|
-| `ground_drop` (PhysX) | the asset is dropped onto a ground plane and must neither penetrate it nor keep moving | `handheld_welding_shield`, `ladder`, `office_chair`, `roller_conveyor`, `wheelbarrow` |
-| `slope_drop` (PhysX) | the asset is placed on a ramp and must slide without penetrating the surface | `a_frame_sign`, `handtruck`, `safety_cone`, `steel_drum`, `storage_rack`, `traffic_cone`, `wheelbarrow` |
-| `culling_xz` (PhysX and Newton) | the asset is rotated under diagnostic shading to catch inverted normals or single-sided geometry | `frame_cart`, `handtruck` |
-#### 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 |
-These assets are authored for PhysX. The Newton results above are reported for information.

+# 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 complete folder for the asset you need.
+2. Keep the package definition, metadata, USD files, materials, textures, and thumbnails together, preserving relative paths.
+3. Open or reference the entry-point USD at `<asset>/simready_usd/<asset>.usd` in NVIDIA Isaac Sim.
+4. Review the per-asset validation and benchmark results before integrating the asset into your simulation. Use a fixed dataset commit for reproducible evaluation.
+## Validation
+Each of the 50 assets includes validation evidence for the **`Robotics-Prop` profile, version `4.0.0`**, under `<asset>/.metadata/`. See the [SimReady Central guidance](https://docs.omniverse.nvidia.com/simready/latest/simready-central.html) for the submission workflow.
+### Schema validation
+The published `simready-validate` reports (version `2026.8.0`) record **no blocking feature failures across all 50 assets**. Individual optional features are not necessarily satisfied; inspect `<asset>/.metadata/<asset>_validation.json` for feature-level results.
+### Runtime tests
+The published benchmark reports contain tests for **PhysX** (`isaac_sim`) and **Newton** (`isaac_sim_newton`). Engine versions are recorded as **Isaac Sim 6.1.0.0** where populated; some interrupted entries have an empty version field.
+| Runtime | Passed tests | Failed tests | Skipped tests | Assets with no failed tests |
+| --- | ---: | ---: | ---: | ---: |
+| PhysX | 547 | 15 | 13 | 37 / 50 |
+| Newton | 398 | 47 | 5 | 43 / 50 |
+| Combined | 945 | 62 | 18 | 33 / 50 |
+Counts summarize the 1,025 test entries in the published per-asset reports. The asset counts above allow skipped tests and do not mean that every test passed. Per-asset results are available at `<asset>/.metadata/<asset>_benchmark.json`.
+#### Engine crashes
+For `fire_extinguisher`, `lancable`, `power_strip`, `respirator`, and `safety_goggles`, all nine Newton tests per asset are recorded as failed because the engine session crashed before completion. These account for 45 of the 62 failed entries. They represent interrupted tests, not completed measurements demonstrating a geometry or physics defect.
+Four of these assets have no failed PhysX tests; `safety_goggles` also has a failed PhysX `ground_drop` entry in the published report.
+#### Other failed test entries
+| Test | Runtime | Assets |
+| --- | --- | --- |
+| `ground_drop` | PhysX | `handheld_welding_shield`, `ladder`, `office_chair`, `roller_conveyor`, `safety_goggles`, `wheelbarrow` |
+| `slope_drop` | PhysX | `a_frame_sign`, `handtruck`, `safety_cone`, `steel_drum`, `storage_rack`, `traffic_cone`, `wheelbarrow` |
+| `culling_xz` | PhysX and Newton | `frame_cart`, `handtruck` |
+Consult each report's message and metrics to distinguish an engine interruption from a completed test that did not meet its criteria.
+#### Skipped tests
+| Test | Runtime | Assets | Reason |
+| --- | --- | --- | --- |
+| `joint_movement` | PhysX | `crowbar`, `hammer`, `paint_bucket`, `power_strip`, `scraper`, `screwdriver`, `signal_tower`, `storage_rack` | No movable joints; the test does not apply. |
+| `pivot` | PhysX and Newton | `crowbar`, `hammer`, `scraper`, `screwdriver`, `spanner` | The benchmark treats sub-threshold pivot/origin scores as advisory and records them as skipped. |
+These assets are authored for PhysX. Newton results are included for evaluation and do not establish full compatibility. Validation and runtime results describe the recorded test conditions, not blanket suitability for every robotics task or NVIDIA acceptance.
+## Repository Layout
+Each asset is published as a separate package at the repository root. The previous top-level `assets/` and `reports/` directories have been replaced by per-asset packages and metadata.
