Add Friar hook on robinhood

[hooklist-generator]

Summary

Volatility-responsive dynamic LP fee hook using the Liquidity Book volatility-accumulator model. Sets per-swap LP fees based on recent price movement — low base fee in calm markets that surges with volatility and decays over configurable windows. No owner, no upgradeability; all parameters are immutable.

Address Flags

Address suffix 0x1080 = 4224 = 0b01_0000_1000_0000:

• Bit 12 → afterInitialize: true ✓
• Bit 7 → beforeSwap: true ✓
• All other 12 bits → false ✓

Matches both the hook file and the source's getHookPermissions().

Chain / Metadata

• chain: "robinhood" → chainId: 4663 matches chains.json ✓
• verifiedSource: true confirmed by source_meta.json ("verified": true) ✓
• name: "Friar" matches contractName in source meta and the NatSpec @title ✓
• description accurately describes the Liquidity Book volatility-accumulator fee model; no promotional/audit/endorsement language ✓

Properties

Property	Claimed	Verdict
dynamicFee	true	✓ — beforeSwap returns fee | LPFeeLibrary.OVERRIDE_FEE_FLAG
upgradeable	false	✓ — no proxy, no admin, all constructor params are immutable
requiresCustomSwapData	false	✓ — bytes calldata hookData in beforeSwap is never read
vanillaSwap	false	✓ — required because dynamicFee is true
swapAccess	"none"	✓ — beforeSwap only has onlyPoolManager; no user-level access control

All values are correct. Approving.
