Every wallet, every ledger: fifteen months of history, verified twice

Two independent engines were reconciled over the pools’ entire lifetime, extending the earlier tip-window check to roughly fifteen months of mainnet history.

• 37,973 wallets replayed over 6,848,288 mainnet ledgers by an engine that shares no code with the production fold.
• Of 885,796 gold rows, 834,525 match exactly; the remainder are benign flush-cadence re-emits. None were unwitnessed.
• All 100 residual divergences are defects in the older engine, including an on-chain eviction the single-engine fold never saw.

Re-reading the same history straight from the public data lake produced byte-identical results.
