====yes,
Good, you understand. Now stop claiming that K
must be uniform when C is fixed. It might be, but
it might not be.
but what can you conclude.
That if we do not know whether or not M is uniform,
we do not know if whether or not K is uniform when
C is fixed.
Thus
If we consider only the OTP without considering the
prior probability on M, we do not know whether
of not M is uniform. So if we consider only the OTP
and a fixed C we do not know whether or not
K is uniform.

=========you should know what is precondition, in that case i
regardless of M prior
note I say:"
I just regardless one of the conditions such as M prior and K
uniform
to make show there need a compromise . "
but what can you conclude.

we do not know if whether or not K is uniform when
C is fixed.

====== my precondition is not the same as you,do not falsify my
statement
i consider C fixed, k uniform, regardless P prior
i consider C fixed, P Prior , regardless k uniform
under the two Probability are conflicting.
