- probe balance delta: 1

## Interpretation

This resilience harness proves that the Devnet operator surface can recover from a dead RPC endpoint and from a transaction assembled with a stale blockhash. The successful path is a rejected stale transaction followed by one recovered transaction on a fresh blockhash, without protocol mutation drift or ambiguous retry behavior.
