A second engine agrees with us, byte for byte

An independent engine that shares no code with the production fold reproduced the served mainnet gold over a recent window, the first cross-engine check on mainnet data.

• A Rust batch engine replayed 119,831 mainnet ledgers from a pinned state snapshot.
• Of 17,865 shared-coordinate rows, all but one agree exactly.
• The single disagreement was settled by the live chain, in the independent engine’s favor, and fixed.
