Add FloorPad Floor Hook hook on base

[hooklist-generator]

Summary

Singleton Uniswap v4 hook serving all FloorPad memecoins (per-pool state keyed by poolId). On each buy, diverts a dynamic cut of the WETH input into a per-pool vault and fees to protocol/creator; on each sell, skims a fee from the WETH output. The vault backs a WETH-per-token redemption floor that ratchets up only on buys; holders can burn coins to redeem at the floor at any time.

All 14 flags match. Confirmed by getHookPermissions() in source.

Properties

• dynamicFee: false ✓ — No lpFeeOverride and no updateDynamicLPFee() call anywhere. The "dynamic cut" is an internal vault accounting mechanism, not an LP fee override.
• upgradeable: false ✓ — No proxy pattern, no delegatecall, no mutable implementation storage, no SELFDESTRUCT.
• requiresCustomSwapData: false ✓ — The bytes calldata hookData parameter is unnamed and unused in both beforeSwap and afterSwap. Swaps work without custom data.
• vanillaSwap: false ✓ — Both beforeSwapReturnsDelta and afterSwapReturnsDelta are true; the hook actively diverts WETH from the swap flow on buys and sells.
• swapAccess: "none" ✓ — beforeSwap only reverts if the pool isn't registered (launchTime == 0); there is no caller allowlist, time gate, or governance flag controlling who can swap.

Metadata

• chainId: 8453 ✓ — Matches chains.json entry for "base".
• verifiedSource: true ✓ — Confirmed by source_meta.json ("verified": true).
• name: "FloorPad Floor Hook" ✓ — Contract is named FloorHook; the NatSpec body explicitly references "FloorPad coins" throughout (@title FloorHook — SINGLETON … serving ALL FloorPad coins). Project-qualified label is substantiated.
• description ✓ — Accurately describes the singleton architecture (per-pool state via mapping(bytes32 poolId => PoolState)), buy-side dynamic cut into vault, sell-side fee skim via afterSwapReturnsDelta, buy-only floor ratchet, and redeem() function. No audit claims, safety guarantees, or marketing language.
