"""READ-ONLY reproduction: Onyx BAYC (oBAYC)
New identity/state probe; NOT executed when this map was built.
The map has no archived output for this specific new probe. No result is assumed.
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.
