🎯 Conclusion

All assessment and documentation tasks are complete. The new WETH contracts (WETH10, CCIPWETH9Bridge, CCIPWETH10Bridge) are independent, compile successfully, and are ready for deployment.

The remaining tasks depend on a decision regarding the solution approach for existing contracts that require OpenZeppelin. Once a decision is made, the implementation and verification tasks can proceed.
