Morphology
beyond + a + shadow + of + a + doubt
The core sense 'without doubt' can be partly derived from the constituents 'beyond' and 'doubt', so a learner might guess the general direction of meaning. However, 'a shadow of a doubt' is a metaphorical element ('shadow' = a slight trace) that is idiomatic and adds emphatic force; this figurative step may not be fully predictable for a B1 learner. Because part of the meaning is compositional but the metaphorical modifier is non-literal, the expression is best judged semi-transparent.
Etymology
Beyond a shadow of a doubt may come from the picture of a very bright light that leaves no shadow. So if something is beyond a shadow of a doubt, there is no sign of doubt left and you are 'completely certain'.
