+/// The five constructor arguments reproduce the address immutables the live implementation
+/// (`0x5253D4C91e80b880DdB54B78E74082Abe066F6b9`, deployed for Proposal0019) carries, and the
+/// script reads them back from the live proxy before broadcasting so a drifted `LibL1Addrs`
+/// constant aborts the run instead of baking into the new immutables. The numeric configuration is
+/// hardcoded in `MainnetInbox`, so after deploying, the script compares the new implementation's
+/// `getConfig()` with the live proxy's and aborts unless the basefee sharing percentage is the
+/// only difference.
+///
+/// Diffing the implementation's dependency tree from the commit the live implementation was built
+/// from (`9078278909a43a83fc5bb2664f30b81eb5c967f6`) to `main` leaves `MainnetInbox.sol` and
