Not true. Electrodynamics is basically the study of accelerating particles, since those are all that can be observed. (The fields that Faraday and Maxwell hypothesized can't be directly observed, but they can be used as conceptual elements to predict the behavior of particles.)

Right, although it turned out that the equations that he believed applied only in terms of the inertial coordinates in which the ether is at rest actually apply equally well in terms of every system of inertial coordinates.

As previously mentioned, the observed relationship between velocity and kinetic energy of high speed particles disagrees sharply with Newtonian mechanics and is consistent with relativistic mechanics and electrodynamics.

Be careful. You said I'd been raving about the gravity field being affected, and I answered that the gravitational field isn't affected at all by the speed of the particles, and then I went on to note that different trajectories obviously follow different paths, which is not "exactly what you said" at all.
Remember, the original point at issue in this digression was whether the behavior of charged particles in accelerators could be explained by saying "hey, maybe the electric force drops to zero as the particle approaches the speed of light". I explained why (as is well known) this is not a viable explanation, because the kinetic energy of the particle continues to increase by F*ds as the force continues to be applied. It is true that, in the curved space-time of general relativity, the "acceleration of gravity" has a dependence on coordinate speed, but this does not alter the empirically verified relationship between kinetic energy and velocity in electrodynamics.

To the contrary, that equation has been verified to many significant digits. It is one of the most precisely verified expressions in science. Particles moving at 0.99999c are routinely observed, and they exhibit the behavior predicted by that equation very precisely.

That's a bewildering conjunction of seemingly conflicted statements. Regarding the centuries-old debate between field theories and action-at-a-distance theories, you comment first that we should regard fields as real entities, and second that action-at-a-distance is a real physical process. So, you are supporting both sides of the debate simultaneously. Then you make the surprising complaint that modern physics remains confined to considering just the four dimensions (x,y,z,t), despite that fact that modern theoretical physicists speed much of their time working on theories in 10 or 11 dimensions (e.g., string theory), and despite the fact that there have been "many-time" theories (i.e., theories with extra time dimensions) dating back at least to Dirac.

You mis-read my sentence. I said all the consequences of special relativity follow from the WRFB effect on the kinetic energy of accelerated particles.

Special relativity can be deduced from the pre-existing facts in many different ways, and Einstein chose a way that is puzzling to some people. It can be deduced in ways that are very clear and direct, making no reference to a mechanistic ether at any point, but historically special relativity was first deduced by reconciling the emission (ballistic) and wave (ether) conceptions of physics. Einstein's two postulates basically represent those two conceptions. The relativity principle is consistent with the ballistic theory, and the light-speed principle is consistent with the wave/ether theory.
Remember, just weeks before writing his EMB paper, Einstein had finished his paper on the photo-electric effect, postulating that light behaves, at least in some ways, like Newtonian ballistic corpuscles, rather than like waves in an ether. (For man years everyone, including Planck, thought he was wrong, until experiments ultimately proved him right.) But he also knew the undeniable empirical success of Maxwell's equations. (He did not feel free to discount empirical facts simply because they disagreed with his pet theory.) So the challenge was to reconcile these.
The key to the reconciliation is what you have called the WFRB, which represents the inertia of energy. This is the key fact that was missing from Newton's physics. Einstein stumbled into this indirectly, as a necessary condition in order for the two conceptions (ballistic and ether) to be reconciled. But once the key was recognized, we find that the mechanistic ether concept must actually be discarded, because the WFRB implies that the speed of light is c in terms of not just one particular inertial coordinate system (the "ether" system), but in terms of EVERY inertial coordinate system, which isn't really compatible with a mechanistic ether conception.
And then the deeper understanding emerged, based on recognizing (with Poincare and Minkowski) the invariants implicit in the Lorentz transformation, showing that the absolute interval between two events separated by dt, dx is given by dtau^2 = dt^2 - dx^2/c^2, and it follows that light propagates along null intervals in this (pseudo) metrical spacetime.
So, when you ask "What unifies the speeds of light from two sources in different states of motion?", the answer is that light (indeed, any massless energy) propagates along null intervals, which are invariants in space-time.
