Is this susceptible to any of S3's eventual consistency constraints?

Anything you read from S3 is, so yes.

The best way to prevent eventual consistency issues in s3 is to use immutable files. Then you have consistency-now.

They don't have explicit SLAs on this, unfortunately, but I've heard rumored that internal pagers start firing with consistency behind on the order of hours.

I'm not aware of S3's consistency constraints. What are those?
