test: cover the approval line and the policy records

Registry cases (none / once / round / grant / YOLO / denial / error / handler
record / closest answer wins), the wire cap keeping the line, the three policy
paths that record their answer, and a pretty detail that ignores the header.
The existing confirm tests now assert the line they gain.
