The floor.
Every figure below is read from the hook or shown as —. Nothing is converted to dollars, and a value that could not be read is never printed as zero.
The deck covers every free SAGE at the floor
R ≥ F · S
R is the raw NVDAc in the deck. S is the SAGE that could still reach it: the supply, less what the protocol holds, less what is spoken for by pairs with cash drawn. F is the floor. Everything is in raw tokens.
It is asserted at the end of every state-changing call, not only where it looks necessary. The floor rises only on reserve that arrives: the pool's cut and interest on repayment. Both are one-way, which is what a one-way floor can be built on.
The contracts
The pool charges 1% at a tick spacing of 200. The hook's address carries its own permission bits, which is why it is mined rather than simply deployed. NVDAc is pinned by address rather than resolved by symbol.
