There is NO idempotency key for a Solana send — every invocation builds a
distinct transaction against a fresh blockhash — so timeout is genuinely
ambiguous: the transaction may still land. All three states carry the
signature because it is known locally the moment the transaction is signed,
before broadcast, so even a timeout links to the explorer.
The result of one on-chain send.
