Epochs and claims

An epoch covers the prints between two closing sweeps, made at 00:00 UTC. At the close the keeper sweeps every pair with fees, sets each wallet's tier from its 30-day volume, and computes for every wallet and pair:

rebate(wallet, pair) = share(tier of wallet) × Σ platform fee the wallet paid on Outcry curve trades in the pair during the epoch

It builds a Merkle tree per pair and posts the root with post_epoch. In the same instruction the program moves the part of the epoch's 75% the root doesn't allocate to the protocol PDA, and refuses a root whose total would pass that 75%, so allocated rebates never exceed what was swept.

Claiming

• Rebates shows today's accruing rebate per pair, each closed epoch with your amount, and its claim state.
• Claim all claims every open epoch and pair in one transaction, with its proofs; a large backlog goes out in as few transactions as fit.
• Each epoch and wallet claims once: the claim writes a receipt that blocks a second claim.
• A rebate is always less than the fee that earned it, so trading against yourself to climb a tier costs money.
