How do Sarah's cards 4, 12, 13 and 17 work when she lacks the needed workers?

Question

Accepted Answer

Card 4 uses as many of her craftsmen as possible when she builds or upgrades. Card 12 is always doable because her specialization supplies the workers; the alternative is one step on the bird track. On cards 13 and 17 the movement icon gives only extra movement when she is not a shearer specialist, with no extra card.
