Add RehypHook hook on base

[hooklist-generator]

Summary

A custom bonding-curve AMM hook that owns all pool liquidity internally, blocking external LP deposits and donations. Swaps exchange WETH/USDC/GHO for REHYP tokens using reserve-based pricing; excess assets are deposited into Aave V3 to earn yield, which can be harvested to increase reserves and burn REHYP supply.

Properties Verification

• dynamicFee: false ✓ — beforeSwap returns a fee override of 0 (static); key.fee != 0 causes revert, so pools are created with fee = 0. No updateDynamicLPFee() call anywhere.

• upgradeable: false ✓ — No proxy pattern, no delegatecall, no mutable implementation pointer, no SELFDESTRUCT. All state is in the contract itself.

• requiresCustomSwapData: false ✓ — The hookData parameter in beforeSwap is completely ignored (bytes calldata with no usage). Swaps function normally with empty hookData.

• vanillaSwap: false ✓ — Correct: beforeSwapReturnsDelta is true and the hook fully overrides swap execution using a custom bonding curve (reserve-based pricing). The hook takes assets from the pool manager and releases REHYP (or vice versa) entirely via BeforeSwapDelta, bypassing standard AMM math entirely.

• swapAccess: "allowlist" ✓ — _checkLaunchGuard() checks launchGuardAllowed[tx.origin] against an explicitly managed allowlist mapping. The guard can be permanently disabled by the launchGuardManager, but when active it is an allowlist gating mechanism.

Metadata Verification

• verifiedSource: true ✓ — Confirmed by source_meta.json: "verified": true.
• chainId: 8453 ✓ — Matches chains.json entry for base.
• name: "RehypHook" ✓ — Matches contractName in source_meta.json and the Solidity contract declaration contract RehypHook.
• description ✓ — All claims are substantiated by the source: bonding-curve AMM with virtual + real reserves; beforeAddLiquidity/beforeRemoveLiquidity revert with NoLP() (no external LP); beforeDonate reverts with NoDonate(); swaps exchange assets for REHYP using reserve-based pricing; _depositExcessRaw deposits excess into Aave V3 (aave.supply()); harvestYield collects Aave yield, increases xReserve, and burns REHYP supply via _burnRehypClaimsOutsideSwap. No audit, safety, or marketing language present.

All flags, properties, and metadata are correct.
