Well, I took your advice and spent some additional time with the constructor to see what was going on. I was using a hash with default values for cell_format that populated every date during construction. Problem was, I accidentally populated every date with a reference to the default hash (and the same reference at that.) For some reason format_cell2 was changing the value of my default hash which instantly changed all the places where that hash was referenced. Bad Trimbach. Bad.

It's clear that's what happened, although I don't grok why that hash was getting changed at all, but hey, I fixed it and now everything works. Thanks Chromatic (and everyone else) for sparking the idea that led me to the solution... and I promise to play nicer with references in the future.
