Why no rare-alignment recurrence: its required sign-combination {Pisces / Aquarius / Capricorn / Aries} never coincides in any of the 12505 rare alignments. This is the everyday timescale — the noise floor every word sits on. The years→centuries alignment gap does not apply here because the word's required signs never all coincide at any of the scanned alignments. (Everyday cadence from the 2026 reference scan; planet periods are stable, so it is the same in any year.)
