Match assets and native graphics
The package includes no original game assets or mod artwork. Apps may select immutable per-match asset packages through the request. This is a scoped filename overlay for admitted IFF assets, not unrestricted resource injection or safe live hot-swap.
An asset package is a versioned ZIP with the exact manifest/schema defined in OpenAPI. Register/upload it through /v1/asset-packages, or supply {path,sha256} entries in the match request's asset_packages. The server validates bounded archive paths, declared hashes, permitted kinds, conflicts and size/storage limits before freezing the selected files. Never execute a community installer to ingest artwork.
Selected packages are frozen before game creation and held immutable for that run. /v1/platform and snapshot.native_platform report native configuration, resolved arena, asset opens and metadata commitment. A validated package or selected overlay is not proof that every texture/animation rendered correctly. The accepted original/college tests verified both specifically selected IFF opens. Broader asset types, resource lifetime replacement during play and custom presentation GPU drawing remain separate.
The compact single-texture court standard is 8192×4096 artwork with 6016×3200 playing-court pixels, compatible UV-remapped IFF and DXT5/BC3 DDS. College scoring geometry applies globally through hooks; arbitrary art still requires compatible UVs. Existing artwork hosting remains independent of this package. Do not publish original assets with an SDK distribution.
Automatic 21:9/32:9 framing/UI corrections are included in the hook. Recorded GPU checks used 3440×1440 and 5120×1440 render targets on a 16:9 physical display. Physical ultrawide/fullscreen/device-reset certification remains open; retain that boundary when reporting support.
The presentation project currently has a data bridge and software/offscreen renderer studies. This team package does not claim game GPU integration, native scoreboard/watermark/replay-wipe suppression, or a finished ESPN CBB package.
