How is that any different from saying it arrives at t' = L/c?

???

D sends the signal at speed c^2/0.1c, so that is the speed that your
"concurrent observer" sees (DUH!)  The lab observer will measure the
speed as infinitely fast.

Any observer at rest in S' measures the signal speed as 0.1c DUH!
It arrives at C at t' = 0.1L/c.  What the heck are you babbling about?

Prok, I have shown that you completely misunderstood my thesis
whereas the reviewer of DOI: 10.13189/ujpa.2023.170101 did not
or he would have rejected it.  Rather than acknowledge your
error and try to understand, you launch another baseless attack
because of your confusion about what v means.  It is the speed
that D must send the signal (Event E1) so it arrives when C and
A are adjacent (E2).  Furthermore, A must send a signal to B
when B is adjacent to D.  Your figures are only half of the full
problem, and they do NOT describe my "proposal."  They are your
imaginings.  If you want to discuss my thesis, then use my
figures (4 and 5, particularly).  Yours are straw men.

And you haven't acknowledged your confusion about what frame
is the "stationary" one in the right and left figures.  Just
proclaiming a frame as stationary doesn't make it so, particularly
when you draw its time axis skewed.
