| # Dataset format |
|
|
| The `cases/castaigne25` split contains one row per object, identified by `case_id` (`R01`–`R25`). Its Parquet table contains native image and list features. [Case definitions](../cases/castaigne25.json) retain each fault's stable `defect_id`, repair requirements and object-specific scope. |
|
|
| | Field | Type | Meaning | |
| | --- | --- | --- | |
| | `original_image`, `broken_image` | Image | PNG previews of the source and damaged asset stages, embedded as image bytes. A null value means no preview is supplied. | |
| | `case_id` | string | Stable object repair task identifier. | |
| | `title`, `asset_id` | string | Object name and NVIDIA source package identifier. | |
| | `source_revision`, `source_url` | string | Immutable source revision and source package page. | |
| | `license` | string | Source asset licence. | |
| | `fault_count` | int64 | Number of specified faults for the object. | |
| | `faults` | list of records | Each item contains `defect_id` and `description`. `fault_count` equals the list's length. | |
| | `failure_story` | string | The export or authoring failure represented by the task. | |
| | `required_outcome`, `scope` | string | Repair requirements and limits of the task. | |
| | `agent_evidence` | string | Description of supporting task evidence. | |
| | `whole_package_path`, `whole_entrypoint` | string | Browsable source package directory under `assets/whole/` and its vendor OpenUSD entrypoint. | |
| | `broken_package_path`, `broken_entrypoint` | string | Browsable damaged package directory under `assets/broken/` and its `asset.usdc` entrypoint. | |
| | `package_path`, `package_sha256` | string | Package path relative to the dataset repository and its SHA-256 digest. | |
| | `episode_paths` | list of strings | Paths to started repair episode manifests for the object. Prepared records and fixtures are excluded. | |
| | `verification_scope` | list of strings | Explicit checks recorded for the supplied package. | |
|
|
| The [preview manifest](../previews/manifest.json) records the asset and PNG hashes, renderer settings and diagnostic overlays. Source and damaged previews are tied to their respective asset bytes. PNGs also remain available under `previews/`. The JSONL companion retains native fault and check arrays and uses relative image paths; `data/cases.parquet` is the viewer's data source. |
|
|
| Browse source and damaged USD files directly through their package directories, or download the damaged archive. Download a package and its dependencies together. Keep source attribution and licence notices with any derived asset. OpenUSD composition checks establish authored structure; dynamic motion, contact and rendering require their corresponding runtime measurements. |
|
|
| Repair episodes are separate records linked by `case_id` and `episode_id`. [The trajectory schema](../schema/trajectory.schema.json) describes observations, tool calls and asset snapshots. Objective measurements and LLM judge assessments belong to the episode's evaluation records; they do not change the identity or contents of the input object. |
|
|
| An `episode_paths` entry can be a [public episode reference](../schema/episode-reference.schema.json). Such a reference identifies the immutable input, Harbor task version and recorded run, together with the hashes and archive paths of the trajectory, final submission, grades and analysis. The submitted USD and its resources belong under `artifacts/submission/` in the trial archive. Compare the input and result hashes when joining an episode to its case. |
