When doing a database diff, I noticed that the table for SITEASSOC_CONTEXT_ASSOCIATIO wasn't being created. This was probably because of the pack moving around and the hibernate file for that pack wasn't in there. Looking at the history I haven't seen these files meaningfully touched in years and really don't know what they're for. I say to just remove them all.
Nobody here knows what this is for the first commit was
SAK-15710 Merging changes from branch into trunk
