I've been looking around trying to find an explanation for how arcane sanctum works.  There's another thread that discussed workplaces but I don't feel that arcane sanctum was sufficiently explained.  The relevant text:

Your home may have, for free, a single library, lab, workshop, or arcane library or sanctum of a quality equal to two steps lower than your Resources. As described in Scholarship (see page 142), the quality of a workplace determines the highest possible difficulty of a “question” or project that you can pursue there.

(YS, p 140)

Provided you are willing to spend time researching (and that the answer can be found), the only questions are how long it will take you and how good a workspace you have access to (usually a library for book things, a laboratory for experimental research, etc.) to discover the answer.

  (YS, p 142)

Academic research requires a library (page 140), while research through experimentation requires a laboratory. The quality of these workspaces determines the hardest possible question you can answer within them (so a question of Good difficulty requires a Good library or better). 

(YS p 142)

This seems to be saying that if you have Good resources, for example, the best you can get is a Fair sanctum, which means that anything you make can't have any strength higher than fair, unless you have connections that let's you cast magic elsewhere.  I don't think that's right as there's no indication of such a limit elsewhere.  Am I completely missing something?
