Term	Kind	Topic	What it is
Background Work on Mobile	concept	Push & Background Work	Work scheduled outside the foreground session, which mobile operating systems aggressively restrict to protect battery life.
Best Effort Delivery	concept	Push & Background Work	The guarantee push notification services actually offer — which is none — and the design consequences of building on a channel that may silently drop.
Push Token Decay Stale Registration Token, Push Target Rot	concept	Push & Background Work	The steady accumulation of push targets that no longer reach a device - which inflates fan-out cost and makes delivery metrics describe a list rather than an audience.
