test(uniswap): validate proposal 100 v4 fees

[blockfulintern]

Summary

• independently reconstructs all 7 executable calls in UNI proposal 100 from named contracts and Solidity interfaces
• verifies Ethereum plus Arbitrum, Base, BNB Chain, Polygon, Optimism, and Robinhood Chain bridge messages
• compares the manual derivation byte-for-byte with the live proposal calldata

Security review

Verdict: APPROVE

All targets, values, selectors, and nested cross-chain payloads match the live proposal. The simulation executes successfully and confirms:

• Ethereum PoolManager changes its protocol fee controller from zero to the deployed V4FeeAdapter
• both Arbitrum-style retryable tickets spend the exact expected ETH
• each remote-chain bridge or messenger emits exactly one delivery event
• Governor and Timelock retain no retryable-ticket ETH

No critical or important findings.
