THE MASONIC CALENDARS — the five dating eras of Freemasonry, carved on cornerstones and printed on charters for three centuries: ANNO LUCIS (Craft, CE + 4000 — Ussher's 4004 BC rounded for the Year of Light, the rounding disclosed), ANNO INVENTIONIS (Royal Arch, + 530), ANNO DEPOSITIONIS (Cryptic, + 1000), ANNO ORDINIS (Knights Templar, − 1118, with the founding identity 1118 → year 0 asserted), and the Scottish Rite's ANNO MUNDI — where the engine does what the old handbooks only gesture at ('add 3760, one more after September'): it CROSS-LOCKS the year to the catalogue's verified Hebrew engine, turning at the TRUE Rosh Hashanah, the 2026 boundary (11 vs 12 September) asserted at load. THE ANCHOR LAW: the U.S. Capitol cornerstone George Washington laid on 18 September 1793, inscribed A.L. 5793 — reproduced by the arithmetic. Symbolic chronology of fraternal tradition, labeled exactly that. Western becomes forty-six. Pure compute, no LLM.
