Background Assets can support a maximum of 200G. Will the Apple server perform file comparison? For example, file0 is included in both a.aar file and b.aar file. On the Apple server, does it occupy twice the size of a single file?

On macOS Tahoe26.0, iOS 26.0 (23A5287g), Xcode 26.0 beta 3 (17A5276g) 1、Follow this tutorial Downloading asset packs hosted by Apple When i download a background asset packs hosted by Apple, Xcode callback "Download failed: The helper received an invalid server response with the status code “400”." Before downloading, I uploaded the three aar files to the Apple server using the Transporter app. Three Manifest.json content is： {"assetPackID":"bdassets2","downloadPolicy":{"onDemand":{}},"fileSelectors":[{"file":"1.jpg"},{"file":"2.pag"},{"file":"3.mp4"}],"platforms":["iOS"]} and {"assetPackID":"bdassets1","downloadPolicy":{"prefetch":{"installationEventTypes":["firstInstallation","subsequentUpdate"]}},"fileSelectors":[{"file":"1.jpg"},{"file":"2.pag"},{"file":"3.mp4"},{"directory":"a1"}],"platforms":["iOS"]} and {"assetPackID":"bdassets0","downloadPolicy":{"essential":{"installationEventTypes":["firstInstallation","subsequentUpdate"]}},"fileSelectors":[{"file":"1.jpg"},{"file":"2.pag"},{"file":"3.mp4"},{"directory":"a1"}],"platforms":["iOS"]} The same error was reported when the three aar files were obtained. I obtained it using the following code: do {       let assetPack = try await AssetPackManager.shared.assetPack(withID: "bdassets2")       try await AssetPackManager.shared.ensureLocalAvailability(of: assetPack)     } catch {       print("Download failed:", error)     } 2、Follow this tutorial Testing your asset packs locally I use this command line to start the test server：xcrun ba-serve --host 172.17.9.62 bdassets2.aar, The content displayed on the terminal is： Loading asset packs… Loading the asset pack at “bdassets2.aar”… Choose an identity in the panel to continue. Listening on port 56061… When running the project, Xcode reports an error:Download failed: Could not connect to the server. I use iPhone directly visit this website: https://172.17.9.62:56061, on the page display "Hello, world!" There are too few error messages in both of the above questions. I have no idea what the specific reasons are.I hope someone can offer some guidance. Best Regards.
