It is not really assumed true before there is sufficient proof. Sufficient means repeatable and sustained by other evidence. Even than all scientific truths are considered tentative truths, not absolute truths. They are considered true in the sense that from them it is possible to build descriptive and predictive models with some precision and reliability. So in science, contrary to what most people think, absolute truth does not really exist.
1. So how IS logic supposed to work??
2. The assuption that something is true is/has been used as a starting point for scientific investigation which has resulted in the assumtion in question either being validated or declared false.
Also logical truth are truths under the asumption of logical foundation. Mathematical truths are truths under the assumption of their foundation, they don't necessarily apply to reality. A good example is Euclid's Geometry, it's valid under its basic assumptions but Einstein showed that it is essentially not valid in our spacetime. Since in our spacetime matter curves spacetime the basic rules of EG are not valid, especially near massive objects. In practice however EG is accurate enough to give good descriptions in most cases.
So essentially you are saying there is no such thing as 'truth'? Only what is observable??
