I suggest to take another look for the software behaviour.

Please compare details with the following SmPL code example.

@find@
expression action, check, result;
position p;
statement is, es;
@@
 result = action(...);
 if@p (
(     <+... result ...+>
&     check
)     )
     is
 else
     es


Under which circumstances will the Coccinelle software provide duplicate data
for their processing by (Python) script rules?


> The database itself doesn't bring any value.

Another unique constraint violation was noticed by using such technology.
I am curious when you are going to take related functionality better into account.

Markus
