Code Review

This pull request updates the verification configuration, test assertions, and documentation for the FactoryStaker contract to include its correct ABI-encoded constructor argument (the owner address 0x9775137314fE595c943712B0b336327dfa80aE8A). There are no review comments, and I have no additional feedback to provide.
