uniswap-v2-reborn: reconstructing Uniswap v2 from deployed bytecode

uniswap-v2-reborn reconstructs Uniswap v2 factory, pair and Router02 behavior from deployed EVM runtime bytecode using REA interface inspection, storage probing and written specifications. It provides a TypeScript model, Solidity 0.8 contracts and a differential harness that compares both with the original bytecode; the author reports 4,800 fuzzed operations without mismatches and exact replay of 426 historical swaps.
