Right.
But you cannot have two forces which are reaction forces
to each other.
Remember:
Newtonian mechanic from Newton's three laws of motion
is thoroughly confirmed as long the involved speeds
are small compared to the speed of light.
There are only three ways you can have two equal forces
between two objects. (Or combinations of the three ways.)
Let's see these ways in detail:
Mass of body A: Ma = 800 kg
Mass of body B: Mb = 3000 kg
#1:
An external force F1 is exerted on body A.
Body A exerts a force F2 on body B.
Body B exerts a force F3 on body A.
Body A exerts a force F4 on the object that exerted the force F1 on it.
F4 is reaction force to F1. F4 = F1
F3 is reaction force to F2. F3 = F2
Given: F3 = F2 = 500N
Acceleration of body B: Ab = F2/Mb = (500/3000)m/s² = 0.1667 m/s²
Acceleration of body A: Aa = 0.1667 m/s²
The force F5 accelerating body A: F5 = Aa⋅Ma = 0.1667⋅800N = 133.33N
F1 = F5+F3 = 633.33 N
We can let an external force accelerate body B
and do the same calculations:
#2: An external force F = 2375 N is exerted on body B
and both bodies will accelerate at 0.625 m/s²
(Body A is accelerated by 500 N)
#3: A force Fa = 500 N is exerted on body A.
A force Fb = 500 N is exerted on body B.
Body A exerts a force Fra = 500 N on body B.
Body B exerts a force Frb = 500 N on body A.
Fra is reaction force to Fb, Fra = Fb
Frb is reaction force to Fa, Frb = Fa
Net force on body A = Fa - Frb = 0 N
Net force on body B = Fb - Fra = 0 N
Acceleration of both bodies = 0 m/s²

The three possible perspectives are described above.

The contact is permanent. Not an event.

Nonsense.
If you put two bodies in contact with each other without
external forces, there is obviously no forces between the bodies.
Quote from 3. Co-Moving Bodies and the Contact Boundary
"Applying Newton's Second Law individually to each body in isolation:
Body A: 500 N = 800 kg × a => a = 0.625 m/s²
Body B: 500 N = 3000 kg × a' => a'= 0.1667 m/s²
In standard Newtonian mechanics these two results reflect
the individual free-body analysis of each mass under the
contact force."
This is nonsense. You cannot have what you call a "contact force"
between the bodies without external forces.
(When the bodies are electrically neutral and without magnetism.)
You are claiming that two bodies repel each other.
Free energy!!

Quite.
As explained in the three perspectives above.

Sorry Yanick.
I have not read your whole paper, I stopped at your claims about
Newton's third law in the introduction.
With such a wrong starting point your theory can not be meaningful.
