138-year cycle of civilizational reset derived by Breshears (Archaix) from synchronizing 40 ancient calendars across a 3,000-year Chronicon timeline. Gregorian anchor hits: 1902 (Pelée/Santa María/Soufrière synchronized volcanism), 1764 (post-Seven-Years-War / Lisbon aftermath), 1626 (Thirty Years' War / plague collapse), 1488, 1349 (Black Death peak), 1212. Next transit window: May 14-22, 2040 — pre-committed falsification protocol for Framework #1. Apr 17 2026 adversarial-neutral audit (external research) integrated: the 138-year metronome survives as a sociophysics phase-transition parameter (Framework #6-compatible) independent of Breshears' literal Planet Phoenix mechanism. Ancient pre-1000 AD anchors that rely on Fomenko-style chronology compression are quarantined. See concept: 'Temporal Convergence Accumulation' for why 3/8 framework convergence at 14 years out is correct engine behavior.
