I don't understand clearly your protocol.
All what I say in step 5 is that a teleportation from x to y without
annihilation of the "original" (thus at x) is equivalent with a
duplication, with annihilation of the original from x to (x and y). In
x, an absence of annihilation can be considered as an annihilation
followed by a reconstitution with a zero delay. This follows from
digitalism which prevents to use a notion of continuity based on the
reals, for example.
This is already in contradiction with Robert Nozick who uses a notion
of closer continuer. From the first person point of view, such
"topology" cannot be recognized.
Second question: in step 6, again assuming the measure is 1/2 in the
preceding steps. Am I correct in my understanding that what you are
describing is the doctor, instead of reconstituting me in Brussels, is
merely taking the digital description of me and giving it as input

That is, after T seconds of simulated time, the program has a new
description of me, one that reflects T seconds of experience in the
Yes, in case the description of you has been made at the correct
substitution level. Somehow you are the program, and the virtual
machine simulates Brussels perfectly (for a non null duration).

for step 5, except that instead of actually being in Brussels either

Yes, except that in all steps, the experiencer knows the protocol in
advance, so he/she knows that he/she is in a virtual environment, like
in a video game or in a lucid dream.
Step 6 recapitulates all the five preceding steps, except that the
reconstitution are done in virtual (digital simulation) of the
Are you OK with the first six steps? Assuming comp! I am only asking
if you see that those propositions follow from the comp hypothesis
(not if you believe them!).
