One function record [nameIdx, sigIdx, cgIdx, propBits, fileIdx, line] (sigIdx/cgIdx/fileIdx are -1 when
absent), with an optional trailing topicIdx (the Rd help topic, present only when it differs from the name).
The trailing element is additive: readers that stop at line ignore it, so older bundles stay readable.
