The mechanism

It deploys the token, whose constructor mints the entire fixed supply and splits it there and then between the ratchet and a wallet the launcher names. Neither share ever passes through the launchpad, and both mints appear in the receipt.

Then it opens a Uniswap v4 pool of native ETH against the token, LP fee zero and the pawl in the key, priced at the top of the range, and turns the ratchet's share in as one position.

Liquidity leaves a v4 pool through exactly one door, a modifyLiquidity call with a negative delta. The only such call in that contract passes a positive one. There is no withdraw, no owner, no pause, no rescue and no upgrade, and the position is a row in the pool manager rather than an NFT, so there is nothing to transfer, sell or lend against.

A fee is taken on everything paid into a pool, in either direction, and all of it goes to the payee written into the pawl at deployment. No creator cut, no treasury cut, no setter. The rate is a constant; read it off the contract rather than from this page.

A pool's hook is part of its key, so the rate is decided when the pool opens and cannot be raised or switched off afterwards. Because the pool's own LP fee is zero, the pawl's rate is the entire fee schedule. And there is no fee for clicking: the door is free.
