Chinese calendar for a date: lunar date (with leap month), zodiac, day officer 建除, yellow/black path, six-day cycle — computed on Beijing time
DiscoveredXuan Kong flying star natal chart: nine palaces with mountain/facing/period stars plus classical pattern labels (e.g. 旺山旺向). Period from a construction date, or explicit yun
DiscoveredIndoor form-sha from a floor-plan wireframe: 穿堂煞 (door-window alignment), 缺角 (nine-palace missing corners), 厕占中宫 (toilet at centre) — plus optional fusion with the Eight Mansions house stars and Ming Gua. Grade B verdicts, no aggregate score
DiscoveredFour pillars (BaZi) for a date+hour, returned under BOTH year conventions (Lichun vs Lunar New Year) × BOTH day boundaries (midnight vs 23:00) — differences are shown, not hidden
DiscoveredMing Gua (Kua number) from birth date + gender, with the Lichun year boundary computed astronomically, five-yellow substitution conventions, and eight favourable/unfavourable directions
DiscoveredVerifiability as an API call: recompute a stored request and compare its SHA-256 input digest (JCS-canonicalised) against an expected value — byte-identical reproduction or honest mismatch
DiscoveredList the rule sets the kernel actually implements, with parameters and honest review_state — nothing not implemented is advertised
DiscoveredAll 24 solar terms of a year with exact Beijing instants. Model: VSOP87D apparent solar longitude + nutation + aberration + ΔT; root tolerance 1e-7 day (~8.6 ms); verified against an independent JPL DE441-based reconstruction. ΔT and midnight-margin uncertainty flags included.
DiscoveredSun azimuth/elevation for a location and instant (solar compass numeric base): azimuth 0=north clockwise, geometric vs apparent (Sæmundsson refraction) elevation, declination, hour angle, explicit polar day/night state — measurement link only, no direction is inferred from photos
DiscoveredWhite tiger elevation check (白虎抬头) from a DEM-derived 360-bin skyline: compares the right (white tiger) vs left (azure dragon) sector elevation within ±45° of the sitting direction
DiscoveredSan Yuan period (三元九运, 1–9) for a date; periods switch at Lichun, anchored 1984 = start of Period 7
