THE MOLAD ANNOUNCEMENT — on the Sabbath before each new month, synagogues worldwide announce the calculated instant of the mean new moon in a format unchanged for a millennium: weekday, hours, minutes and CHALAKIM — 1,080 parts to the hour, one chelek = 3⅓ seconds. THE PRECISION LAW is the awe, asserted at load: the traditional lunation (29d 12h 793ch = 29.5305941 days) sits about HALF A SECOND PER MONTH from the true synodic mean — a constant carried from Babylonian astronomy through Ptolemy to Hillel II that modern instruments barely correct. THE WITNESSED CELL: molad Tishrei 5786, published as Monday 12:10 p.m. and 7 chalakim, reproduced EXACTLY (day 2, 18h, 187 parts from the evening). THE CROSS-LOCK: an independent implementation of the millennium-old machinery, with Rosh Hashanah from the catalogue's verified Hebrew engine proven to fall inside the dechiyot window after this engine's molad, four years running. WHY 1,080: it divides evenly by 2,3,4,5,6,8,9,10 — the divisibility roll asserted. The mean-vs-true-moon distinction stated as the system itself states it. Kabbalistic becomes ten. Pure compute, no LLM.
