Two earlier attempts asked the model to reason from the age (a voice clause
with no birth date; an age_years field it ignored). The server now decides:
when the native is ELDER_PARENTS_AGE_THRESHOLD (65) or older at the request's
UTC+8 calendar date, the parents, family and general sections carry one plain
sentence right under the label, parents_life_stage, with the age in it. Below
65, or with no birth date, nothing is added. The birth date, time and place
still never reach the model; no prompt rule changes.
The biography backtest reads each figure's real birth date from the golden
instead of 1950-01-01 and passes its request time.
