This is occurring on an M1 MacBook Pro 2021, macOS Sequoia 15.1.1.
I've seen some warnings/errors running disk first aid through Disk Utility. I see the same errors running it from the command line. I run this on the data partition:
fsck_apfs -n -l -S /dev/disk3s5
I get the following output:

I've run this, (without '-n -l -S'), several times in repair mode (as suggested in various places), both in normal user mode and in recovery mode. It never seems to change. I've deleted the partition snapshots too, without any change to these messages.
So, first question, is… what's wrong? And is it actually 'repaired' as it suggests? Yet probably not, because I get the same every time I run the disk check?
And next question is, how do I know what doc-id 337, file-id 9124874 refers to? Apple documentation is particularly useless here. (What's the point of an error message if there's nowhere to find out what it means!?).
Then there's the descendants (8586) of dir-stats object (id 294597) is greater than expected (6774) message. Where do I find object 'id 294597' so I can try and check its size?
