"""READ-ONLY reproduction: Arbitrum Delayed Inbox
Reconstructed for portability; NOT rerun when this map was built.
The map displays older archived evidence, not output generated by this script.
Default RPC: https://rpc.pulsechain.com (public). Override with --rpc. Python standard library only; no keys/signatures/broadcasts.
Archive-state access is required at the saved block. trace_callMany is client-dependent.
