... and today we've discovered that the input field on which I've been relying to link data between two systems is, in fact, not shared between those systems. It _can_ be, but there's no mandate that it must, so our hit rate is low teens. Because everything is a manual process and nobody has a consistent data model and my project relies on interoperability between those systems.
I'm unconscionably angry right now, because I was so hung up on whether or not I'd be able to interface with the old legacy system that I never stopped to ask whether the new system would be feeding me the data I needed to make the old system do stuff. And it _can_, but it presently... isn't.
