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 link actual attempts to their inputs, responses and submitted repairs. Scoring explains partial credit and the per-turn reporting available with the repair-progress integration.
