Description

In AccessControlDefaultAdminRules.sol, you can't execute on inclusion block + scheduled delay but rather, inclusion block + scheduled delay + 1. This is a rather strange pattern since time limits are usually enforced as block.timestamp >= expectedTimestamp. I presume this is intended to induce a delay when schedule timestamp == block.timestamp but has been left undocumented.

💻 Environment
v5.3.0 OZ
v1 Foundry

📝 Details
I think this should be documented or fixed. I don't strictly view it as a bug but it's a definite pitfall.

🔢 Code to reproduce bug

  • multicall([...], [...])
    • beginDefaultAdminTransfer(...)
    • acceptDefaultAdminTransfer()

Research direction

Start in contracts/access/extensions/AccessControlDefaultAdminRules.sol around _hasSchedulePassed at line 369, then reproduce the boundary case with beginDefaultAdminTransfer(...) and acceptDefaultAdminTransfer() in one multicall. Compare the observed inclusion-block timing with the intended behavior; done means the behavior is corrected or its timing is explicitly documented, as decided in the issue.
