Question regarding Cache FS and how it evicts

[usrme]

I have a setup with a really large cache (see snippet from values file below) and I'm not sure based on what criteria exactly the eviction from local disk to S3 is being made. Based on this white paper it’s based on access times:

Since the maximum size can be set, artifacts in this cache will “rotate” based on their last downloaded date or creation/modified date.

But I have a concrete example of a blob that was created today (at the time of writing) that is already stored in S3:

$ stat /var/opt/jfrog/artifactory/data/cache/ff/ff7e66484d8723c7f1a7b1622e018604c2131581
  File: /var/opt/jfrog/artifactory/data/cache/ff/ff7e66484d8723c7f1a7b1622e018604c2131581
  Size: 34946           Blocks: 72         IO Block: 4096   regular file

 Birth: 2024-11-26 08:34:34.971291759 +0000

I'd really love some clarification around this and to learn if I've possibly misconfigured something. I tried to grep the name of the blob across /var/opt/jfrog/artifactory/log and /opt/jfrog/artifactory/var/log, but nothing came up.

Could it be that I'm misunderstanding that significance of the files in that directory and that they end up there after whatever the configured cache settings are for any given remote repository? If so, where do they reside before they end up in that directory then and how does the S3 storage relate to the cache directory?
