Objective: Find all file references from non-deleted records pointing to a missing (non-existing) file.

Assumptions:
- a perfect integrity of the reference index table (always update the reference index table before using this tool!)
- relevant soft reference parsers applied everywhere file references are used inline

Files may be missing for these reasons (except software bugs):
- someone manually deleted the file inside fileadmin/ or another user maintained folder. If the reference was a soft reference (opposite to a TCEmain managed file relation from "group" type fields), technically it is not an error although it might be a mistake that someone did so.
- someone manually deleted the file inside the uploads/ folder (typically containing managed files) which is an error since no user interaction should take place there.

Objective: Find all record references pointing to a missing (non-existing or deleted-flagged) record.
Assumptions:
- a perfect integrity of the reference index table (always update the reference index table before using this tool!)
- all database references to check are integers greater than zero
- does not check if a referenced record is inside an offline branch, another workspace etc. which could make the reference useless in reality or otherwise question integrity
Records may be missing for these reasons (except software bugs):
- someone deleted the record which is technically not an error although it might be a mistake that someone did so.
- after flushing published versions and/or deleted-flagged records a number of new missing references might appear; those were pointing to records just flushed.
