Programs like the SMART program are very special programs designed to rehabilitate a defendant with a substance abuse problem, not only by providing a course of treatment but by giving them the tools to live a more productive lifestyle. It works on a contract system, in which a defendant agrees to be bound by the rules of the program -- all of them -- not just the ones relating to drugs or alcohol.
Adherence to all of the program's policies for a specified period of time -- here apparently 5 months -- allows a defendant essentially to work off his or her conviction, graduate from the program and get a clean start. Any violation of the program can lead to a demotion, on the one hand, and additional time in the program or the jail or prison sentence that the defendant avoided in the first place by agreeing to get help with his or her problem.
All of this is typically spelled out in advance to the defendant by the court and the defendant must agree to be bound by all of these rules and to waive his right to appeal the decision of the court.
So the dilemma is exactly what your daughter has been told. She has had a program set back due to her breaking the rules of the program. Because whatever was going on was not drug or alcohol related and also not a new crime but just a breaking of the program's rules, she's lost her clean time and must make that up. Or, if she'd rather, and I don't see why she would, she can do her time and forget getting help and a clean start.
This is how these specialty court programs work all over the nation. Texas is doing nothing more than enforcing the contract your daughter agreed to.
Once the court finds out that your daughter absconded, they will issue a warrant for her arrest. When that happens, your daughter would be hurting her chances of being able to resolve her program violation with a phase setback and increasing the likelihood that she will be bounced from the program altogether and made to serve her time. If that happens, she does not get jail credit for time in the program, but will be sentenced to what she agreed her punishment would be when she gave up her rights to challenge all this, including her right to appeal, by agreeing to the SMART program.
I would urge you to tell her to return to court or the program as soon as possible to ensure that she can remain in the program.
