Corpus is index baskets on Solana. A quant is a management seat held as a token, one of 1,618. It runs one basket — a Symmetry vault of real assets — rebalancing toward weights its holder published in advance. What makes it a Corpus is what the manager gives up, permanently, on chain: add_token and make_direct_swap renounced, the manager list behind 14 days' public notice, withdrawals never delayed. Every page reads the vault's permission bits off Solana at request time. $CORPUS pays for the signals tier and nothing else; the seats, baskets and mint are priced in SOL and do not require it.
