Tzade

The left head of the above TZADEs appear like a kav peshuta. There are many poskim who invalidate and others who are matir. Each case needs to be independently assessed, and so this is a she'elat Hakham. The question here is if the small Tzavits are considered significant enough for us to correct the letter by adding a clear head, or if it should be outright invalidated. Your insight is appreciated.
