Feiteng Bafa (飛騰八法) (飛騰八法)

飛騰八法 — the FLYING-SOARING EIGHT METHODS (奇經納干法), the sibling of 靈龜八法 in Xu Feng's 針灸大全 (1439) and the simpler of the pair: no sums, no divisors — the HOUR STEM alone names the open confluent point, whatever the day and hour branch: 壬甲→公孫(乾), 丙→內關(艮), 戊→足臨泣(坎), 庚→外關(震), 辛→後溪(巽), 乙癸→申脈(坤), 己→列缺(離), 丁→照海(兌), taken with its host-guest partner. SERVED AS HERITAGE, NOT MEDICINE — NOT_MEDICAL_ADVICE is the first payload field, enforced by test. TWO WITNESSES on all ten stems (the classic's text via 中医世家 + the Kepu China exposition); THE CLASSIC'S OWN WORKED EXAMPLE as load-time anchors (甲/己日: 戊辰時→足臨泣, 己巳時→列缺, 庚午時→外關), the pairing example (臨泣配外關) proven against the shared 八脈交會 partner table, and the 五子元遁 hour-stem derivation shared with the sibling engine. HONEST SIBLINGHOOD: the two methods open DIFFERENT points on many hours (甲子日子時: 飛騰 公孫, 靈龜 內關) and seat four points on different trigrams — each verse served as its own, never blended; the tradition holds both. Returns the rule, the open point with this method's trigram, the partner, and the day's twelve-hour schedule. Pure compute, no LLM.
