USE when comparing exactly two people by Gregorian date. NOT for one date (moon/season/Rx/weekday/leap year/day_ruler → get_date) or names → get_name. Requires date_a and date_b. RETURNS scored dyad: cosmic_card_a/b (each side is full get_date shape incl. tarot_majors.greer/tarot_school, karma, planetary_spread; Cosmic card = birth = life = sun via also_called; planetary_spread and retrogrades_active planets include planet_type/symbol/emoji + names{} 10 cultures; each planetary_spread slot carries spread_pos 1-14 — sort by spread_pos for canonical Life-spread order), connections, overall_score, Chinese zodiac + true sidereal aspects, element harmony, life paths. temporal_context.date_a/b = {band, payload_scope} (full|extended|out_of_range × full|cosmic_card_only; 1900-2100 focus).

PRIMARY single-date tool. USE for any one Gregorian date when the ask needs moon phase (incl. blue/blood/supermoon/micromoon flags, Earth-Moon distance, phase_gmt, prev/next blue or blood dates), season/equinox anchors, classical retrogrades (retrogrades_active phase=retrograde), calendars, lunar year, Cosmic card (same card as life/sun — cosmic.also_called + planetary_spread.sun), karmic source/spirit, 14 planetary Life-spread cards, weekday or leap year (calendar_meta.weekday / is_leap_year), day_ruler (weekday planetary ruler Roman/Greek/Norse), or full date identity. NOT for two-person scoring → get_compatibility; name text → get_name. RETURNS cosmic block (incl. karma + planetary_spread) + tarot_majors (greer + tarot_school) + day_ruler (full+extended) + temporal blocks (moon_phase, season, retrogrades_active, calendar_meta, …). planetary_spread and retrogrades_active planets include planet_type/symbol/emoji + names{} (greek,norse,celtic,egyptian,sumerian,babylonian,mesopotamian,arabic,sanskrit,chinese). Each planetary_spread slot carries spread_pos (1-14 canonical Life-spread order; midheaven=13, phoenix=14 — sort by spread_pos; jsonb object keys are unordered). temporal_context={band, payload_scope} (band full|extended|out_of_range; payload_scope full|cosmic_card_only). Out-of-range responses set cosmic_card_available.

RETURNS compact cosmic birth card + age_spread {age_civil, age_no (mod 90), age_aliases, age_spread_pos, planet_row, planet_col, is_fixed_card}. Feb-29 follows Postgres age(). Error as_of_before_birth when as_of_date < birth_date.
