Every address the simulation touched, ordered by screening priority rather than by where it appeared in the transaction. The parties to the transaction come first, then the Safe and the contracts a batch pointed at, then the contracts that were merely called. Position means nothing beyond that, so it should not be read as the order in which effects happened.

Show child attributes
Present only when the calldata decoded as a Safe execTransaction and the Safe answered. For every other transaction this field is absent altogether, rather than null or an empty object.
Show child attributes
Show child attributes
One object per MultiSend entry, in payload order. Null whenever safe.batch_state is not decoded, and absent alongside safe. The arrays above carry applied effects only, so on a failed batch they are empty while each entry still reports what it attempted.
