| # Dataset format |
|
|
| The `cases` configuration exposes the `castaigne25` split in `data/cases.parquet`. Each row identifies one versioned repair task. The JSONL companion uses relative image paths. Parquet embeds the PNG bytes as native Image values. |
|
|
| | Fields | Contents | |
| | --- | --- | |
| | `original_image`, `broken_image` | The correctly modelled reference and the exact task's supplied broken-input observation | |
| | `case_id`, `dataset_version`, `title`, `asset_id` | Stable object lineage, release version and object identity | |
| | `source_revision`, `source_url`, `license` | Pinned NVIDIA source and its licence | |
| | `faults`, `fault_count` | A native list of `{defect_id, description}` records and its length | |
| | `required_outcome`, `repair_brief` | Repair requirement and the path to the task's submission instructions | |
| | `image_state` | Authored pose or a recorded physical-probe observation | |
| | `whole_package_path`, `whole_entrypoint` | Browsable correctly modelled package and USD entrypoint | |
| | `whole_package_archive`, `whole_package_sha256` | Complete reference archive and SHA-256 | |
| | `broken_package_path`, `broken_entrypoint` | Browsable broken package and USD entrypoint | |
| | `package_path`, `package_sha256` | Complete actor-input archive and SHA-256 | |
| | `broken_asset_sha256`, `whole_asset_sha256` | Exact packaged USD digests | |
| | `task_revision`, `harbor_task_digest`, `harbor_task_url` | Immutable native task identity and its Harbor location | |
| | `episode_paths` | Native list of published model-attempt records, empty when no records are included | |
| | `verification_scope` | Native list of the checks attached to this input and task version | |
|
|
| Paths are relative to the dataset repository. Extract the complete archive before opening `asset.usdc`, so its resources retain their relative paths. The reference keeps the correctly modelled scene in a portable package. Legitimate dents, wear and component poses belong to that object. A reference is not a model's submitted repair. |
|
|
| The broken USD, resources and observation match the native task's actor input. Browsable folders add package metadata and a square gallery thumbnail without changing those input bytes. Reference images stay outside native gallery discovery paths, so the gallery opens the broken objects. |
|
|
| `release.json` pins the collection and its tasks. A task revision changes when its input, instructions or verifier changes. The stable case ID connects that object's versions. [Episode records](episodes.md) link actual attempts to their inputs, responses and submitted repairs. [Scoring](scoring.md) explains partial credit and the per-turn reporting available with the repair-progress integration. |
