TOWER-Assets

Versioned simulation assets for the TOWER Benchmark. Immutable Hugging Face tags identify releases; artifact paths remain stable.

Modular layout

manifest.json                         aggregate download index
releases/<version>.json               exact module set for one release
modules/stations/*.json               shared station modules
modules/tasks/*.json                  independently versioned task families
station/*                             shared USD/USDZ station payloads
tasks/*                               task scenes, initial states, and thin USDA layers
metadata/task-catalog.json            discoverable task-family index

Each tower-asset-module-v1 document owns its dependencies, artifacts, checksums, variants, and task metric protocol. A new task family adds one module document and its payloads; release tooling discovers it through a tower-asset-release-v1 descriptor without a code registry change.

Task USDA files compose the shared station and add only task-specific prims or overrides. Checkpoint-bound scene JSON uses portable asset:// and generator:// references. Dataset provenance uses non-executable dataset:// identifiers. Machine-local paths and local validation reports are not release artifacts.

The older tower_transfer, cross_tower_transfer, and aligned_stack USDA files remain staging descriptors. Release 0.0.3 adds complete composed layout layers and checkpoint-bound scenes for selected Task 2, 4, 5, and 6 variants; the module descriptor is authoritative for each variant's contents.
