One Object, Three Readings: The Aethel-Psi Synthesis — A Unified Theory of the Primordial Waveform, Quantum Gravity, Dimensionality, Dark Energy, and Information. Third Revised Edition

The Aethel-Psi Synthesis treats a primordial harmonic waveform, a complex scalar tracking Quantum Fisher Information, and the principal eigenstate of the Fundamental Cosmological Matrix as three readings of one object. This Third Revised Edition folds in the six repairs directed after the Second Revised Edition and reports each with the verdict of validation suite v5. What closes. The coupling xi = -1/6 is now derived, but only under an explicitly stated operator D_Psi in the scalar sector. The ACT DR6 test is closed as a measurement: on real DR6.02 TT data there is no ripple, global p = 0.241, with a 95%-power upper limit A < 0.016. The gravitational-wave stacking forecast is corrected and a four-event stacked profile on real strain is reported. What partially closes. The gamma(M) prediction is accepted as gamma approx 0.009 (logistic form) or 0 (rational form), flat in mass, and Revised Prediction 1, gamma < approx 0.08 at 95% for GW250114-like mergers, sits inside the full parameter-estimation posterior. The neutrino test is narrowed to a single testable form, the failed-supernova black-hole-formation cutoff. The GW231123 35 Hz residual survives precession at profile level. What fails or is dropped. No bundle or Chern-Simons level gives beta_A = 1/14, so beta_A is fitted and the Planck anchor is a stated assumption. The stated potential gives no phantom crossing at a_c = 0.476 or at the DESI value 0.7116, and its dark-energy density is negative today. The Lambda cancellation fails on all three counts and Lambda_eff identically 0 is dropped, not proven. A full precessing parameter estimation for GW231123 was still running when v5 was recorded, so no posterior or Bayes factor for that event is claimed here. Validation suite v5: PASS=25 FAIL=18 OPEN=6. A one-page v6 addendum in this record reports tests run after this edition was built.
