## Tools (as reported by the server, not verified)

- `calendar`: 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
- `ganzhi`: Four 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
- `solar\_terms`: All 24 solar terms of a year with exact Beijing instants \(DE441-based\), ΔT, and midnight-margin uncertainty flags
- `kua\_number`: Ming Gua \(Kua number\) from birth date + gender, with the Lichun year boundary computed astronomically, five-yellow substitution conventions, and eight favourable/unfavourable directions
- `flying\_star\_chart`: Xuan 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
- `yun\_period`: San Yuan period \(三元九运, 1–9\) for a date; periods switch at Lichun, anchored 1984 = start of Period 7
- `rulesets`: List the rule sets the kernel actually implements, with parameters and honest review\_state — nothing not implemented is advertised
- `form\_analysis`: Indoor 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
- `terrain\_white\_tiger`: White 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
- `replay`: Verifiability 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
