THE SHICHIKO NO ZENJITSU (七箇の善日) — the SEVEN LUCKY DAYS of the Japanese almanac's lower section, the auspicious half of the twice-banned row served as rekichuGedan: 天赦日 (the supreme 'heaven forgives all' day, four to six a year), 神吉日 (33 shrine-luck pillars — a uniquely Japanese notation), 大明日 (25 great-brightness pillars, from the Tang Daming calendar), 天恩日 (heaven's grace — three consecutive five-pillar runs), 母倉日, 月徳日 and 鬼宿日. TWO WITNESSES, ONE READ FROM SOURCE CODE: the ja-Wikipedia tables against koyomi8.com — whose pillar lists were extracted from its own JavaScript arrays and agree INDEX FOR INDEX (33/33, 25/25, 15/15). THE THEOREMS AT LOAD: 母倉日 is not a table but WUXING — the lucky branches are exactly those whose element GENERATES the season's element — derived from the generation cycle and proven equal to the witnessed cells for all twelve months; 天恩's three runs, 月徳's three-harmony triads and 天赦's four season-pillars asserted; 鬼宿日's 28-day mansion cycle asserted via the independent lunar-javascript engine — WITH the cross-tradition contradiction carried: the mansion Japan crowns its great lucky day is marked 凶 in the Chinese reading. 神吉's unreconstructed Edo exclusion rules and 大明's 21-pillar variant DISCLOSED, never blended. Japanese becomes twenty systems. Pure compute, no LLM.
