I don't think it is worth arguing with you anymore because I think your just looking for an argument which leads to these stretched out discussions. Propellant-less propulsion has everything to do with the nature of space time.
I am not "looking for an argument," this statement from you is just your latest avoiding of responding to any of the content in my posts.
Spacetime is a concept in actual physics. Propellantless propulsion is something that contradicts a fundamental part of all physics theories. They have basically nothing to do with each other especially in this thread which is about a model of the quantum vacuum. The articles you have been posting in particular say nothing even close to related to this topic, and you have been posting them with no meaningful comment on what they say or why it would be relevant. And no, the latest one also does not answer the question I previously asked that you quoted.

I'd like to play the devil's advocate for a moment. We have no framework for separating the wheat from the chaff for physical relevance. If you have an idea what people should seek out in papers that might be of interest, it would be a great help to know what to look for.

This thread is on a specific topic, specifically White's dynamic vacuum model. Papers about that model would be on topic. Papers about the normal quantum vacuum would not be on topic in general, unless someone found something specific of interest and could explain how it relates to the model (or thruster idea) that is the topic for this thread. For example there is probably a paper out there on the casmir effect that would be helpful in explaining why under the normal understanding of the quantum vacuum devices like this simply wouldn't work.
Papers on general relativity, thermodynamics, quantum gravity, etc. simply would not say anything of relevance to this thread, and if someone thought they did, they should be able to explain exactly why. (quantum gravity is a topic that in particular would need to be handled with care, because there simply is no theory of quantum gravity that is generally accepted, in particular it is difficult to find ones that make testable predictions.)
With the idea that relativity - space-time, gravity, can be merged with a thermal quantum vacuum then I think it may be possible to engineer the vacuum, possibly by quantum vacuum friction. I think quantum vacuum friction is possibly related to merging black holes, and generation of gravitational waves. They mention the braking effect. One variable that might change the friction could be magnetic fields. I was suspecting that magnetic fields are induced currents in the vacuum. Maybe this changes local relative velocities with respect to the vacuum.
Quantum Vacuum Friction in highly magnetized neutron stars

In this letter we calculate the energy loss of a highly magnetized neutron star due to Quantum Vacuum Friction (QVF). Taking into account one-loop corrections in the effective Heisenberg-Euler Lagrangian of the light-light interaction, we derive an analytic expression for QVF allowing us to take into account a magnetic field at the surface of the star as high as 10 11 T. In the case of magnetars, with magnetic fields above the QED critical field, we show that the QVF is the dominating energy loss process. This has important consequences, in particular for the inferred value of the magnetic field. This also indicates the need for independent measurements of magnetic field, energy loss rate, and the braking index in order to fully characterize magnetars.
Here they calculate the optimal trajectory to maximize the Unruh effect observation. You'll notice that they suggest to maximize the change in acceleration which is to maximize the jerk. This has a lot of similarities with respect to Mach effect possibly. Also with black holes they increase their drag on space-time with respect to their increasing velocity and acceleration, edit: when merging and emitting gravitational waves, throwing off energy into space time.
If you want unidirectional observation in only one direction, you want to maximize your jerk in one direction, and minimize it in the other direction. I think this is that waveform where it looks like you have minimized acceleration and velocity at one end and maximized velocity and acceleration at the other. is a fourier sum of frequencies increasing in frequency that are properly in or out of phase with each other.
On the Unruh effect, trajectories and information
Aida Ahmadzadegan, Achim Kempf
Classical and Quantum Gravity 35 (18), 184002, 2018
We calculate the trajectories which maximize the Unruh effect, mode by mode, when given a fixed energy budget for acceleration. We find that Unruh processes are most likely to occur, and therefore are potentially best observable, for certain trajectories whose acceleration is not uniform. In practice, the precise form of optimal trajectories depends on experimental bounds on how fast the acceleration can be changed. We also show that the Unruh spectra of arbitrarily accelerated observers contain the complete information to reconstruct the observers' trajectories
