AI bot answer is not relevant to the question.

You say that code/data is in the same DB that is mirrored. 2025 and 2022 are using different version of journaling, but 2025 is capable of de-journaling journals from previous version (but not the vice versa).

1. When you upgraded the failover to 2025 (the one which is the new primary) did you had any issues with journal files? (might be that some files were dropped in the upgrade and not processed).
2. is that "missing rule" mapped to another DB that is not in mirror?

The Quit command is quitting the if statement therefore no value is allowed.

Clean code is not to have multiple places that quit with value, in long code it is difficult to track. Therefore a nice structure could be:
Ser result=1
If [condition] { ... set result=0 }
else { ... set result=1 }
Quit result 

WIJ (write image journal) is used for data before it is saved to the database. This is used to keep the data consistency (block level in database) and avoid database degradation. If IRIS (or the OS) crash, WIJ will have "dirty blocks" (not written to databases) that will be weritten during the next IRIS startup.

Journal files (or mirror journal, in case you have mirroring) are used after data saved to the database. This will help for transactions rollback and also to ensure a good restore point up to the "current time" along with the latest backup restore.

The sequence is:
1. Read a block was changed from the database
2. Write the modified block to WIJ
3. Write the modified block to the database
4. Write the global SETS and KILLS (and also transaction start/stop) to the journal file
