Investigate significance of some JSON values sent from `launcher.exe` to `Tl.exe`

novadrop/src/client/Client/LauncherGameInfo.cs

Lines 3 to 28 in e2110a7

	sealed class LauncherGameInfo
	{
	// TODO: account_bits, access_level, chars_per_server, user_permission
	[JsonPropertyName("result-code")]
	public int ResultCode { get; } = 200;
	[JsonPropertyName("game_account_name")]
	public string GameAccountName { get; } = "TERA";
	[JsonPropertyName("master_account_name")]
	public string MasterAccountName { get; }
	[JsonPropertyName("ticket")]
	public string Ticket { get; }
	[JsonPropertyName("last_connected_server_id")]
	public int LastServerId { get; }
	public LauncherGameInfo(string accountName, string ticket, int lastServerId)
	{
	MasterAccountName = accountName;
	Ticket = ticket;
	LastServerId = lastServerId;
	}
	}

I seem to remember that they are not actually used by Tl.exe for anything (except chars_per_server), hence their omission in LauncherGameInfo, but we should confirm that.

user_permission is almost certainly related to the permission_mask in the server list XML response. I'd imagine Tl.exe filters out servers that the account doesn't have access to when sending the server list to TERA.exe.

They don't get filtered out, the flag tells the client if user can access a "restricted" server.
A restricted server is a server with permission mask >= 1
If the server appears as restricted client will not attempt to access it unless user_permission >= permission_mask

Edit : This could be either user_permission or access_rights flag, unsure about that part

Read this https://disk.yandex.ru/i/izEgqMLhyi_qLQ about permissions and launcher.

@KYGAS

If the server appears as restricted client will not attempt to access it unless user_permission >= permission_mask

Can you clarify the exact behavior in this case? E.g. in the server list, does the server appear similarly to being offline, or full, or something?
