The cosmic file
No reliable birth time was established in this review, so the profile uses an astrology exemption and presents no Ascendant or houses.
Birth-data confidence: no reliable time verified in this pass; No claim made beyond calendar-date sun sign already present in the prior pack.; Do not calculate or publish houses, Moon, or ascendant until a rated time source is reviewed.. Astrology is interpretive and is never medical prediction. A rising-sign link requires reviewed AA, A or B-rated birth-time evidence without an uncertainty qualifier.
