ØSphera
The house that stewards the Player+ Modules: it keeps them in good order, receives corrections, and holds them open to everyone.
Stewardship here means tending conditions rather than owning a thing. ØSphera does not author the lessons — the houses that play the jams do — and does not decide who may use them. It keeps them true, repairs them, receives what players send back, and makes sure they stay freely available under a share-alike licence, so that anyone may use them, improve them, and pass the improvement on.
It is load-bearing because a living deck needs an address. Corrections travel hand to hand — you tell whoever gave you the lesson, and they tell whoever gave it to them — and that chain has to end somewhere that will actually mend the page. Without a named steward, improvements die one house short of everyone.
A Player+ meets the name twice: at the foot of every lesson, in the line that says who stewards them and under what licence, and when a correction they wrote reaches the people who keep the pages. Nothing about the relationship is governance. A house that takes the lessons owes nothing but the same freedom onward.
What a steward owes in return is legibility: say what changed and why, keep the unsettled questions where the next hand can find them, and decline an offer with a reason rather than with silence.
Its office is the office of any keeper: hold the form, repair it, and keep it open. The lessons remain current best understanding and deserve refinement rather than reverence, including from the house that keeps them.
