Lipseys API and integration
Lipsey's is polled over a dealer API on the usual schedule, so the mechanics of the sync here are ordinary; what is not ordinary is what some of the rows represent. Exclusive Firearms is part of how Lipsey's positions itself — models it describes as produced specifically for its own distribution — and an item like that may simply arrive with no match on this hub to set it beside. When that happens, the absence is a fact about the item rather than a sign that a sync missed something.
What Project Parabellum normalizes from Lipseys
Project Parabellum normalizes every item in the Lipseys feed — manufacturer, model, caliber, and category — into a shared vocabulary, so the same UPC carried by Lipseys can be compared against the same UPC carried by any other distributor we sync, rather than compared only within Lipseys's own naming. Dealers who connect their own Lipseys credentials see account-specific availability on top of that; everyone else sees catalog breadth and stock presence.
