@ shmeur: hitting the hide target will always kill the vivor regardless of whether the hide target was saved or not. this is a bug that has existed for a while. HOWEVER, if the martyr is directly attacked, the role logic causes the martyr to absolutely kill herself, so whether the target visited or not is irrelevant.
the bread lets the town know there's a martyr alive, and that the person who got the bread was saved. this is basically a bg that always dies in place of the target.
