I know the basic accurizing techniques, bedding, free floating & lapping, but what does it mean to "blue print" a rifle?

Generally it includes squaring the bolt lugs to the receiver abutments, and these lugs and abutments 90 degree to the barrel/action centerline, tightening the bolt in the receiver, ensuring that the centerline of the barrel is in alignment with the receiver and much more....

I was taught this means hand building bolt/chamber alignment with perfectly fit components using maximum and minimum recommended clearances. No sloppy "it fits and gauges good enough".

Everything has a specification (a certain size, certain tightness or torque, a certain space or clearance between two things, etc). This list of specs and materials is the "blueprint" of the item. In manufacturing every spec has a window or tolerance where the item's measurement can be and still pass spec (must be between .070" and .090" or something like that). On some items this window may be large and still allow it function relatively well though too tight can be just as bad or worse than too loose.
Blueprinting something means to measure all the specs and either replace parts or modify them so that they will conform to perfect parameters of the "blueprint" or as near as possible. The trick however, is knowing what the perfect parameters are. Sometimes it is in the middle, sometimes it would be on the tight side and sometimes the loose side. You need someone with a lot of experience and expertise to do this so they know, as well as some other tricks to make it even better than what the manufacturer could make even if they did use perfect fitting parts.

it would be the same as blueprinting an engine in a car.
one of the reasons that many upper tier european rifles cost more is that they are already blueprinted at the factory...it's the difference between "correct" and "good enough"
