What the provider says
Solana transaction preview BEFORE signing: simulate an unsigned or signed legacy/v0 transaction (address lookup tables resolved) and get SOL and SPL/Token-2022 balance changes for your wallet, programs invoked (known/unknown), fee estimate and red flags (token approvals, authority/owner changes, close-to-other, wallet reassign, >90% SOL loss, simulation failure). JSON body. Optional Pre-Sign Brief (schema 1.0): pass intent (e.g. 'swap 0.002 SOL for USDC', 'send 0.001 SOL to <address>') and/or context {type, ticker, mint}; get verdict clear|caution|avoid with reasons, intent_match, verified xStocks tokenized-equity check, priority-fee market hint (micro-lamports/CU) and a sha256 brief_hash.

A payment rail is where the provider asks to be paid. It is not proof that anything was paid
through it. See evidence levels.
