I am leaving some of your questions for the experts who also
read this list.

No, please backtrack to this point in your reasoning.
"assigns \nothing ;" does mean "no side effects".

[kernel] preprocessing with "gcc -C -E -I.  t.h"
t.c:5:[kernel] warning: found contradictory assign clauses. Keeping only one

Either you did not pay attention to this warning, or you typed "frama-c t.c".
You do not have to list header files that are included in at least one .c file
in your project, but you have to be aware that frama-c 1) uses standard
pre-processing, and 2) only looks at files you list (modulo clause 1).
