card gains decider_count (1..64) beside deciders, which may now be empty (ids withheld).
record gains answerer_count beside answers; answerer is nullable for the non-decider view.
Generator derives both counts, adds withheld(entry), the non_decider_page scenario and the
R-card/R-record/R-entry/R-list/R-answer-result negatives. optionsHash and bodyDigests
digests are unchanged: neither count nor deciders emptiness enters the hash.
