• bytes expected_code_hash = 5

  A hash of all contracts who's code a UserOperation touches as computed during validation before the UserOperation enters the mempool. As per ERC-4337 requirements, it is later compared against an equivalent hash computed before being added to a Bundle. Specifically, a bundler should reject a UserOperation if, between the time if it was added to the pool and the time it’s taken out to be added to a bundle, any of the code that it touches during validation changes. Therefore, before any UserOperation is added to the pool, validation is run once, keeping track every contract whose code it touches. This hash is computed based on the code of all those contracts. When the second validation runs later, the hash is computed again to verify the code has not changed. See rule (5) here: https://github.com/ethereum/EIPs/blob/master/EIPS/eip-4337.md#specification-1
