 Asset Bridge uses the same owner-authorized BFF, immutable revisions and direct resumable Storage transfers as native packages. Creation and first revision reservation are atomic; an uncertain creation or commit response reuses the saved operation identity, including after selecting the same files again. The selection is checked in full before upload: at most 200 files, 512 MiB per file and 1 GiB total after extraction. ZIP extraction occurs locally in the browser with bounded streaming, verified CRC/size, portable relative paths and matching local/central records. Encrypted, split, ZIP64, symbolic-link and colliding-path ZIP inputs are refused before publication; unpack unsupported archives locally and upload the directory. Only the selected ZIP is expanded; nested archives remain original files. Ordinary file/folder selection can also preserve archive files without extraction.
 
-[`upload-policy.ts`](../src/studio/upload-policy.ts) owns the shared executable/installer extension denylist. Browser intake and the BFF apply it to every incoming revision package, including paths in expanded application bundles and ZIP selections. Scripts, including MATLAB `.m`, and data remain allowed. A regression check covers every current Craft native format through the package validator. Craft-specific native imports and editor saves retain their format validation alongside this policy. Uploaded collections use attachment downloads and a neutral binary media type. Robyn reads them through the existing project-scoped `studio_list_assets` / `studio_open_asset` tools; workstation client 0.10.1 adds zero-byte collection materialization without weakening native/source validation.

Normal Import files sends unrecognized selections to Asset Bridge, which stores the originals with neutral binary types and attachment downloads. Native task exports use known media types when available and preserve unfamiliar formats as binary attachments under the same BFF upload policy. Robyn reads exact collections through the project-scoped `studio_list_assets` / `studio_open_asset` tools.
