 Recommendations:
 If Main invariant 2 is meant to be adhered as stated in readme, then consider removing the filling withdrawal buffer step during reward distribution, as withdrawal buffer is only for the user withdraw claim.

+### Low-14 Hardcode 200_000 gasLimit when sendPrice might not be suitable for all chains, consider adding gaslimit as a param that can be customized.
+**Instances(1)**
+In contracts/Bridge/L1/xRenzoBridge.sol, sendPrice() will hardcode 200_000 as gasLimit to be passed for ccip tx, this gas amount is intended for destination chain tx. 
+
+However, there is no guarantee that 200_000 will be compatible for all possible L2 chains intended. If insufficient gas limit is passed, ccipReceive + L2updatePrice flow will always revert on destination L2.
