Unreachable code detected

Nullability of reference types in return type of 'Task<(bool?, IDownloadState?)> VerificationCache.Get(IDownloadState archive)' doesn't match implicitly implemented member 'Task<(bool? IsValid, IDownloadState State)> IVerificationCache.Get(IDownloadState archive)'.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.

Avoid inexact read with 'System.IO.Stream.ReadAsync(System.Memory<byte>, System.Threading.CancellationToken)' (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca2022)
