Dyer nested Lie-bracket structure ↔ quadratic and higher multi-mode sourcings; octonion associator e4, e5, e6=−2e7 (Paper CVIII) ↔ the cubic mode (2, 2, 0, +) 3. Five zero-parameter predictions follow: (CCXXXIII-1) the cubic-to-fundamental amplitude ratio is the non-associative three-body coupling K/J = n·fbulk = 1. 255% already derived in Paper CXCVIII; (CCXXXIII-2) quadratic mode amplitude ratios follow the Fano-line incidence structure constants 2εijk; (CCXXXIII-3) the overtone tower truncates at nmax=5 from the G2 Cartan depth, with an n=6 recurrence corresponding to the free e7 radial breathing mode of Paper CCXIII; (CCXXXIII-4) retrograde-mode amplitude in anti-aligned-spin binaries scales as sin2 (θmisalign/2) from H+/H− ordering reversal (Paper CXLIX) ; (CCXXXIII-5) the framework predicts a late-time power-law tail of amplitude ∝ a0·M·t in Cauchy-characteristic matching simulations, pre-registered before any such catalog publishes such a measurement. The paper closes a triangle between Paper CCIX (BCH Taylor expansion of spacetime), Paper CCXIII (Onsager 6, 3 disk lock-in), and the GW birefringence prediction of Paper CCXXXII into a unified Lie-algebraic description of ringdown.
