Testing

I ran another copy of slskd with the following adjustment to the upload code:

governor: (tx, req, ct) =>
{
    if (Random.Shared.NextDouble() < 0.5)
    {
        Log.Error("Unlucky!!!");
        throw new Exception("unlucky");
    }
    return Governor.GetBytesAsync(tx.Username, req, ct);
},

This gives uploads a 50% chance of failing each time the governor is asked for a block of bytes, which is every iteration of the send loop. With this in place, I downloaded a directory:

Each file failed and was automatically retried, up to 96 times. I found and fixed a bug with progress reporting in Soulseek.NET here, and with that, everything seems to be working perfectly.
