State root mismatch processing first block

Invalid block error on new payload invalid_hash=0xc0f683b61355455d49af3dbb11fe1f65e9ae8670890d6fb1aadcbf5f8acc960b invalid_number=1 error=mismatched block state root: got 0xf642572d6309b2f2ecad2a6a8b24774beff142d46b525465514feba61f8f601a, expected 0xa59f6ea19d9ee6d7e79bcb286e6d8838b47b48351b37960e24c0a72d41fa1629

When asking Reth to produce the test vectors, Reth rejects its own block

Error while processing payload error=Failed to insert block (hash=0x18b4ca61ed1c11c187bc2d9e8e6de0fb54f9c8372dddbbc65c5d5e5aa3f38c14, number=1, parent_hash=0xa7931c99fd2b7b5e323a2fda8a2dd607cea04f03835c3f29bfe7c057c8b5672e): mismatched block state root: got 0xf642572d6309b2f2ecad2a6a8b24774beff142d46b525465514feba61f8f601a expected 0x9ec3eaf4e6188dfbdd6ade76eaa88289b57c63c9a2cde8d35291d5a29e143d31

But note that there are three roots:

• The state root produced by Netheremind
• The state root produced by Reth
• The state root that Reth claims to get when validating the block

The root mismatch at block production is expected

because block building and block execution are two different things ref: https://github.com/paradigmxyz/reth/blob/9f03f8a269b3f23afd0d3aad4f77fd69c864a68b/crates/ethereum/node/src/node.rs#L216-L216
